CONSULTING SERVICES AGREEMENT

Exhibit 10.1

CONSULTING SERVICES AGREEMENT

THIS CONSULTING SERVICES AGREEMENT (hereinafter “Agreement”), is effective as of the 1st day of August, 2015 (“Effective Date”), by and between TreeHouse Foods, Inc., with its principal place of business at 2021 Spring Road, Suite 600, Oak Brook, IL 60523 (“Company”) and Harry J. Walsh (“Consultant”).

WHEREAS, effective July 31, 2015 (“Retirement Date”), Consultant retired from his employment with the Company and from any and all officer and/or executive positions held with the Company and any of its subsidiaries or affiliates;

WHEREAS, prior to the Retirement Date, Consultant’s employment with the Company was subject to an employment agreement dated January 27, 2005, as amended on November 7, 2008, and February 24, 2014, (the “Prior Employment Agreement”); and

WHEREAS, Company desires to avail itself of Consultant’s temporary and part-time services after such retirement from the Company, and Consultant is willing to provide such services upon the terms and conditions set forth in this Agreement.

NOW THEREFORE, in consideration of the following mutual covenants, it is herein agreed by and between the parties as follows:

1. TERM. The term of Consultant’s services under this Agreement shall, except as it may otherwise be subject to termination hereunder, commence as of the Effective Date and shall continue for twelve (12) months thereafter (“Term”). Notwithstanding the foregoing, this Agreement may be terminated as provided in Section 6 below.

2. DUTIES. During the Term, Consultant will provide services as reasonably requested by the President and Chief Executive Officer of the Company, provided that the time that Consultant devotes to the performance of such services, exclusive of any travel time to or from any location at which Consultant provides such services, shall approximate a 25% time commitment (which in the aggregate constitutes five hundred and twenty (520) hours, calculated as ten hours for each of fifty-two weeks), with the further understanding that each calendar week may require more or less than ten (10) hours to perform the services. In the event Consultant anticipates that the requested services will require him to spend more than five hundred and twenty (520) hours (exclusive of travel time) in the aggregate during the Term, Consultant shall inform the President and Chief Executive Officer of the Company.

3. CONSULTING FEES. Subject to the last sentence of this Section 3, the Company shall pay to Consultant an annual consulting fee (“Consulting Fee”) in the amount of Two Hundred Thousand and 00/100 Dollars ($200,000.00), less applicable taxes as set forth below and any authorized deductions, pro-rated during the Term of this Agreement and payable in equal bimonthly installments; provided, however, that in the event this Agreement is terminated before twelve (12) months from the Effective Date due to Death, Disability, Termination for Cause or Termination by Consultant (as defined in Section 6 below), the Company will have no obligation either to continue making installment payments to Consultant or to pay Consultant any remaining balance on the Consulting Fee. Consultant agrees and acknowledges that the Company will (a) treat the Consulting Fee, and each installment payment thereof, as wage income as if Consultant remained an employee of the Company, within the meaning of federal and state tax laws, during the Term of this Agreement; (b) deduct from each installment payment all applicable federal and state tax withholdings, including without limitation

federal and state income tax, Social Security tax and Medicare tax; and (c) will report the Consulting Fee and payments thereof to the Internal Revenue Service and other appropriate taxing authorities as employment income. Consultant shall not be entitled to any payments or benefits other than those contemplated by this Agreement.

4. BUSINESS EXPENSES. Consultant will be reimbursed for all authorized reasonable expenses incurred in the discharge of his duties under this Agreement, pursuant to the standard reimbursement policies of the Company.

5. OBLIGATIONS ARISING FROM CONTRACTOR’S PRIOR EMPLOYMENT. Consultant agrees and acknowledges that the Employment Period under the Prior Employment Agreement ended on the Retirement Date when Consultant voluntarily retired from his employment with the Company, and that such constitutes a Termination Due To Retirement pursuant to subsection 8(d) of the Prior Employment Agreement. The parties agree that the following sets forth all of their respective obligations arising from the Prior Employment Agreement and/or Consultant’s employment relationship with the Company through the Retirement Date:

A. Health Benefits Continuation Coverage. Consultant agrees and acknowledges that the health benefits insurance coverage to which he was entitled and which he received as an employee of the Company will end on the Retirement Date. Consultant may elect to continue receiving group health insurance after the Retirement Date pursuant to the federal law known as COBRA (29 U.S.C. § 1161 et seq.) for the time period during which he is eligible under COBRA via the COBRA materials that will be provided to Consultant under separate cover. If Consultant elects to receive COBRA coverage and for as long as he remains eligible, Consultant will be responsible for, and his continued receipt of such continuation coverage is contingent upon his, paying the full coverage premium set forth in the Employee’s COBRA billing statements.

B. Incentive Bonus for Calendar Year 2015. The Company acknowledges and agrees that Consultant, as a former employee of the Company who retired from such employment within the meaning of the applicable incentive bonus plan, is entitled to a prorated incentive bonus for 2015. The Company agrees to pay Consultant the incentive bonus for 2015 that Consultant would have become entitled to had Consultant’s employment continued until the date upon which eligibility for such bonus is triggered under the applicable plan, reduced by proration to reflect that portion of the calendar year 2015 during which Consultant was actually employed by the Company (i.e., January 1, 2015, to the Retirement Date). Consultant will receive such prorated bonus at the same time as eligible employees receive the bonus, currently anticipated in or about February 2016. Notwithstanding the foregoing, Consultant’s entitlement to any such bonus for calendar year 2015 is contingent upon Consultant earning such bonus under the applicable plan pursuant to the formula, performance targets and any other criteria set forth in the plan and as established specifically for Consultant and/or Consultant’s organization for 2015. Accordingly, this provision does not guarantee such bonus if no such bonus would have been earned under the applicable formula, performance targets and any other criteria.

C. Final Regular Paycheck as an Employee and Vacation Pay. Consultant acknowledges that Consultant’s final paycheck as an employee of the Company, less applicable taxes required to be withheld and any authorized deductions, has been or will be paid in a final payroll check representing Consultant’s compensation for his base salary through the Retirement Date and for any accrued but unused vacation time.

D. Retirement/401(k) Plan/Stock Equity. Consultant understands and acknowledges that Consultant’s right to continue participation, if any, in any Company sponsored retirement or 401(k) Plan shall be governed by the terms of such plan and not this Agreement, and Company will continue to deduct Consultant contributions and make Company matching contributions, each to the limits allowed under the 401(k) Plan, pursuant to Consultant’s current election unless Consultant modifies such election through proper documentation. Any grants of equity in the Company that Consultant has received, regardless of form or status, shall be governed by the applicable grant and governing plan documents. Nothing in this Agreement shall expand, diminish or otherwise modify Consultant’s or the Company’s rights and obligations contained in any of the aforementioned documents, and the Company strongly recommends that Consultant review the documents. For the avoidance of doubt, Consultant agrees and acknowledges that Consultant’s cessation of employment on July 31, 2015, constitutes a Retirement for all purposes, including without limitation vesting, exercisability, distribution, expiration, forfeiture or cancellation, within the meaning of the TreeHouse Foods, Inc. Equity and Incentive Plan (“EIP”) and any agreements to which Consultant was a party in the context of any equity grants under the EIP.

E. Pre-Retirement Business Expenses. Consultant will be reimbursed for all as-yet-unreimbursed reasonable expenses incurred in the discharge of his employment duties prior to the Retirement Date and authorized by the Company, pursuant to the standard reimbursement policies of the Company.

F. Indemnification. The Company reaffirms and agrees to comply with any continuing obligations it has to Consultant pursuant to the Indemnification provision set forth in subsection 7(d) of the Prior Employment Agreement.

G. Company’s Satisfaction of All Pre-Retirement Obligations to Consultant. Consultant agrees and acknowledges that, other than as set forth in this Section 5, (i) Consultant is entitled to no other benefits or forms of compensation arising from his employment with the Company up through the Retirement Date, including without limitation incentive bonus payments other than as set forth in subsection 5.B above or entitlement to any equity grants other than what he received prior to the Retirement Date; and (ii) all other benefits and forms of compensation shall cease upon the Retirement Date.

H. Termination of Prior Employment Agreement. The Company and Consultant agree that the Prior Employment Agreement is terminated in all respects as of July 31, 2015.

6. TERMINATION OF SERVICES. Notwithstanding Section 1 above, Consultant’s services hereunder may be terminated upon the occurrence of any of the following events:

A. Death. Consultant’s services shall terminate in the event of Consultant’s death.

B. Disability. Consultant’s services shall terminate, at the option of the Company, in the event of the disability of Consultant. For purposes of this Agreement, the term “disability” shall be defined in a manner consistent with the primary long-term disability insurance policy that covers Company employees, or if no long-term disability insurance policy is in effect, the term “disability” shall mean the inability of Consultant to perform his duties for Consultant under this Agreement, as a result of his mental or physical illness or other incapacity, for a period in excess of one hundred fifty (150) consecutive days or any period aggregating one hundred eighty (180) days in any one- year period.

C. Termination for Cause. The Company may terminate Consultant’s services for Cause upon written notice to Consultant. For purposes hereof, “Cause” shall be deemed to exist if any of the following items apply:

(i) The continued failure of Consultant to perform his duties for the Company during the Term (other than by reason of Consultant’s illness or other incapacity) after the Company delivers a written notice to Consultant identifying the manner in which the Company believes that Consultant has failed to perform his duties, and Consultant fails to commence substantial performance of his duties to the reasonable satisfaction of the Company on a continuous basis within two (2) weeks of the date of the notice;

(ii) The commission of any act of fraud, embezzlement, misappropriation, willful misconduct or gross negligence by Consultant with respect to the Company;

(iii) Conviction of Consultant of a criminal offence which substantially relates to Consultant’s performance of services for the Company on behalf of Consultant;

(iv) Breach by Consultant of any of his obligations under the Prior Employment Agreement that continue after the Retirement Date, as reaffirmed by Consultant in subsection 5.H of this Agreement;

(v) Breach by Consultant of any of the terms or conditions set forth in this Agreement, which breach is not cured within two (2) weeks after the Company delivers to Consultant a written notice of such breach, which notice describes in reasonable detail the Company’s belief that Consultant is in breach; or

(vi) Any material violation by Consultant of the TreeHouse Code of Ethics as set forth on the TreeHouse website.

D. Termination by Consultant. Consultant may terminate Consultant’s services for any or no reason upon sixty (60) days’ written notice to the Company.

7. COOPERATION. Consultant agrees to cooperate and assist the Company with any investigation, regulatory matter, lawsuit or other such matter in which the Company is a subject, target or party and as to which Consultant may have pertinent information. Consultant agrees to make Consultant reasonably available for preparation for hearings, proceedings or litigation and for attendance at any pre-trial discovery and trial sessions, if applicable. The Company agrees to make every reasonable effort to provide Consultant with reasonable notice in the event Consultant’s participation is required. The Company agrees to reimburse Consultant reasonable out-of-pocket costs incurred by the Consultant as the direct result of Consultant’s participation,

provided that such out-of-pocket expenses are supported by appropriate documentation and have prior authorization of the Company. Consultant agrees to perform all acts and execute any and all documents that may be reasonably necessary to carry out the provisions of this paragraph. Any time that Consultant spends engaging in any activities pursuant to this Section 7 shall not constitute any of, or contribute to the allotment of, the ten (10) hours per week, on average, to which Consultant has committed to provide services under Section 2 of this Agreement.

8. GENERAL RELEASE.

A. Release and Waiver of All Claims. Consultant, and for Consultant’s heirs, executors, and assigns, does hereby discharge and release the Company, its predecessors and affiliates, including but not limited to the Company, its present and former principals, owners, shareholders, representatives, associates, servants, employees, attorneys, officers, directors, trustees, successors and assigns, and agents of any of the foregoing, from any and all liability or responsibility for all grievances, disputes, actions, causes of action and claims at law or equity, sounding in contract or tort, whether under any state or federal statutory or common law and whether known or unknown, arising out of or related in any way to Consultant’s employment with and cessation of employment with the Company, including but not limited to claims for wrongful discharge, unlawful discrimination, retaliation, breach of contract (express or implied), intentional or negligent infliction of emotional distress, negligence, defamation, duress, fraud, or misrepresentation, any violation of the Age Discrimination in Employment Act of 1967, the Americans with Disabilities Act of 1990, Title VII of the Civil Rights Act of 1964, the Employee Retirement Income Security Act of 1974, the Equal Pay Act of 1963, the Family and Medical Leave Act of 1993, the Fair Labor Standards Act, the Sarbanes-Oxley Act of 2002, the Worker Adjustment Retraining and Notification Act, the National Labor Relations Act, any claim based upon the Company’s 401(k) Plan or deferred compensation plan maintained on behalf of the Company’s employees, the laws of any state, and all claims under related common law, statutes, and executive orders at the federal, state and local levels of government, and any claims to any benefits from employment with the Company, other than those benefits enumerated herein or those benefits to which Consultant is entitled by law.
