Idahoan Butter & Herb Class Action Lawsuit On False-Advertising, What Consumers Need to Know

A class action lawsuit filed in 2025 alleges that Idahoan Foods LLC falsely advertises its instant mashed potato products as containing a meaningful amount of butter, when the actual butter content is negligible. Plaintiff Richard Alonzo filed the lawsuit against Idahoan in New York state court, claiming the “Butter & Herb” branding deceives consumers into paying a price premium. No settlement has been reached.

What Is the Idahoan Lawsuit About? Alonzo v. Idahoan Foods LLC, No. 166090/2025

Plaintiff Richard Alonzo claims Idahoan sells instant mashed potatoes in four-ounce bags described as “Butter & Herb” and “Russet Potatoes with Butter & Parsley” when the amount of butter in the product is “de minimis” — meaning so small as to be practically insignificant.

The core legal theory is false advertising and deceptive business practices under New York General Business Law §§ 349 and 350, which prohibit deceptive acts and false advertising directed at New York consumers. Alonzo argues that Idahoan’s packaging causes purchasers to expect that butter is the exclusive and/or predominant fat or oil in the product, or at least present in a significant amount. The ingredient list, however, places butter after other additives — including Mono- and Diglycerides and Calcium Stearoyl Lactylate — with butter appearing only above “Spice” on the list.

The publicly available ingredient list for Idahoan Butter & Herb Mashed Potatoes confirms this ordering: Potatoes, Vegetable Oil (Coconut, Sunflower, Soybean), Whey, Salt, Dried Corn Syrup, Sugar, Nonfat Dry Milk, Mono- and Diglycerides, Calcium Stearoyl Lactylate, Dried Onion, Natural Flavors, Parsley, Butter (Cream, Salt), Spice. Under FDA regulations, ingredients are listed in descending order by weight — meaning vegetable oils far outweigh butter in the formulation. Alonzo argues that a reasonable consumer who sees “Butter & Herb” on the front of the package does not anticipate that coconut, sunflower, and soybean oils are the dominant fats — not butter.

Alonzo also claims Idahoan’s instant mashed potatoes sell at a premium price of approximately $1.49, and that this price is higher than the product would command if it were represented in a non-misleading way. The case is one of several false advertising lawsuits filed in recent years targeting food brands that prominently feature “butter” in product names while using vegetable oils as primary fat ingredients. Consumers interested in broader false advertising trends in packaged foods can review our Guide to Consumer Class Action Lawsuits.

The lawsuit was filed by Spencer Sheehan of Sheehan & Associates P.C., a firm that has filed numerous similar cases targeting food labels involving butter, margarine, and ingredient misrepresentation. The case is pending before the Supreme Court of the State of New York, County of New York, which handles complex civil litigation for New York County.

Who Is Eligible for the Idahoan Class Action?

No class has been formally certified yet. Based on the complaint, you may be part of the potential plaintiff class if:

• You may qualify if you purchased Idahoan “Butter & Herb” instant mashed potatoes at any time within the applicable statute of limitations period (typically three years under New York GBL § 349).
• You may qualify if you purchased Idahoan “Russet Potatoes with Butter & Parsley” instant mashed potato products.
• You may qualify if you purchased the product in the United States, with particular attention to New York consumers as the primary class definition.
• You may qualify if you purchased the product relying on the “Butter & Herb” or “with Butter” labeling as a signal that butter was a primary or prominent ingredient.
• You may not qualify if you purchased the product knowing the butter content was minimal, or solely for reasons unrelated to the butter labeling.

No action is required from consumers at this stage. If a class is certified and a settlement reached, class members will receive formal notice by mail or email. You can also monitor this case at AllAboutLawyer.com for updates.

Potential Recovery & Legal Theory

Alonzo’s complaint does not name a specific dollar settlement figure — no settlement exists. Under New York General Business Law § 349, successful plaintiffs can recover their actual damages (the price premium paid for the product) or $50 per transaction in statutory damages, whichever is greater. Under GBL § 350, false advertising claims carry statutory damages of $500 per transaction. Plaintiffs are also seeking injunctive relief — a court order that would require Idahoan to change its labeling.

The lawsuit argues that the $1.49 retail price for the four-ounce bags includes a price premium paid because of the false butter representations, and that consumers would have paid less — or not purchased the product at all — had the labeling accurately described the product’s fat composition.

Consumers should understand that courts have divided on similar claims. Several comparable lawsuits against other brands have been dismissed at the motion-to-dismiss stage. A federal court dismissed a nearly identical claim against Bob Evans mashed potatoes, finding that a reasonable consumer would not expect butter to be the exclusive fat in a processed food product. A Wisconsin federal court similarly dismissed a case over Mrs. Smith’s Apple Pie, holding that the label’s “Made with Real Butter” disclosure did not imply a certain amount of butter in the product. Idahoan Foods has not yet filed a response to the complaint. For context on how New York false advertising law applies to similar cases, see our article on food labeling class action lawsuits.

Frequently Asked Questions

Do I need a lawyer to join the Idahoan class action lawsuit? 

No. If the court certifies a class, you will automatically be included as a class member without hiring an attorney. The plaintiff’s law firm — Sheehan & Associates P.C. — represents the class. You would only need your own lawyer if you choose to opt out and pursue a separate individual claim.

Is this lawsuit legitimate? 

Yes. The Idahoan class action is a real lawsuit filed in the Supreme Court of the State of New York, County of New York, under Case No. 166090/2025. It was filed by a licensed attorney, Spencer Sheehan of Sheehan & Associates P.C., under New York General Business Law §§ 349 and 350.

When will a settlement be reached? 

There is no timeline available. The case is in its earliest stage. Class action lawsuits of this type typically take two to four years to reach a settlement — and many are dismissed before that point. Check back at AllAboutLawyer.com for updates.

What if I no longer have my receipt?

 Save what documentation you can now — bank statements, store loyalty card records, or Amazon order history. Whether proof of purchase will be required depends entirely on the terms of any future settlement, which have not yet been negotiated or announced.

Will a settlement payment affect my taxes?

 Possibly. Settlement payments that compensate you for an economic loss (overpaying for a product) are generally not taxable. However, tax treatment depends on how any settlement is structured. Consult a tax professional for advice specific to your situation.

Why does the ingredients list matter in this case? 

Under FDA regulations, all food ingredients must be listed in descending order by weight. Because butter appears near the bottom of Idahoan’s ingredient list — after vegetable oils, whey, salt, corn syrup, and multiple additives — the plaintiff argues that butter constitutes only a trace portion of the product despite the “Butter & Herb” branding.

Have similar lawsuits against other food companies succeeded?

 Results have been mixed. Some courts have dismissed comparable cases, finding that “made with butter” does not guarantee butter is a dominant ingredient. Others have allowed cases to proceed to discovery. The outcome in this case will depend heavily on how the New York court interprets the “reasonable consumer” standard under GBL § 349.

What products are specifically named in this lawsuit? 

The complaint specifically names Idahoan instant mashed potatoes sold in four-ounce bags labeled “Butter & Herb” and “Russet Potatoes with Butter & Parsley.” Other Idahoan varieties are not named in the current complaint.
