Is béarnaise sauce gluten-free?
Classic béarnaise is gluten-free: butter, egg yolk, vinegar, tarragon. The packet mixes are thickened with wheat flour.

Why
Béarnaise is a daughter sauce of hollandaise, and both belong to the one family of French mother sauces that is not built on a roux. Béchamel and velouté start with flour cooked in butter. Hollandaise and béarnaise do not. They get their body from emulsified egg yolk and butterfat. The thickening mechanism is physics, not starch, which is why the classic recipe is naturally gluten-free without anyone having to adapt it.
Scratch béarnaise, in full: white wine vinegar reduced with shallots, tarragon stems and cracked peppercorns; strained; whisked into egg yolks over gentle heat; clarified butter emulsified in; finished with chopped tarragon and chervil. Every one of those is gluten-free. Nothing needs substituting.
The packet mix rebuilds that from powder, and flour is how it does it. The US Knorr Béarnaise Sauce Mix lists maltodextrin, corn starch, enriched wheat flour, salt, sugar, citric acid, yeast extract, sunflower oil, whey protein concentrate, guar gum, spices, turmeric and paprika. Allergen statement: Contains milk and wheat. An older version of the same formula also lists wheat flour. Either way, this is a flour-thickened sauce pretending to be an emulsion, because a dry powder cannot carry enough butterfat and yolk to do the job the real way.
Knorr will not publish a gluten-free flavour list. The company's stated position is that gluten, when present, is named in plain language on the label (wheat flour, rye, barley, oats, malt), and that because formulations change, it does not maintain a list of which flavours are safe. That puts the burden on the panel in front of you, every time.
Jarred béarnaise is the ambiguous middle. These are real emulsions, so they should be clean, but most add a stabilising starch of unstated source:
- Delouis Béarnaise lists water, butter, a tarragon-shallot-vinegar reduction, egg yolk, white wine vinegar, mustard, cream powder, salt, starch, vinegar and xanthan gum. That bare "starch" is the whole question, probably corn or potato, but the label does not say and the product carries no gluten-free claim.
- Maille Béarnaise screens as uncertain for the same reason: ingredients whose gluten status depends on sourcing, with no manufacturer claim to resolve them.
On a French or EU label, an unqualified "starch" is genuinely ambiguous, the US rule that forces "wheat" to be declared behind a modified starch does not apply the same way, though EU allergen law does require cereals containing gluten to be emphasised in the ingredient list. If it is emphasised, it is wheat. If nothing is emphasised, it probably is not, but "probably" is not a gluten-free claim.
How much risk is this?
Celiac disease: avoid packet mixes unless the packet says gluten-free. Scratch béarnaise and a jarred sauce carrying an actual gluten-free claim are both fine. Restaurant béarnaise is usually made properly and is one of the safer sauces on a steakhouse menu, but ask, because some kitchens stabilise a service-volume béarnaise with a starch or a base product.
Non-celiac gluten sensitivity: same guidance, lower stakes.
Wheat allergy: the Knorr mix declares wheat. The jarred sauces declare egg and milk, which matter more to most people in this category.
The steak is the bigger risk than the sauce. Béarnaise arrives on steak frites, and the frites are the problem, shared fryers with breaded items are the most common way people get glutened at a steakhouse, not the sauce.
What to have instead
- Make itTwelve minutes, one pan, one bowl. Reduce 60 ml white wine vinegar with a chopped shallot, tarragon stems and peppercorns to about two tablespoons. Strain, whisk into three egg yolks over a bain-marie, stream in 150 g melted clarified butter, finish with chopped tarragon. This is the answer, and it beats every commercial version on taste anyway.
- Maison Potier BéarnaiseA jarred French sauce that carries a gluten-free claim, the clearest ready-made option we found.
- Mayacamas Béarnaise Sauce MixA dry mix labelled gluten-free, thickened with rice flour instead of wheat. The obvious swap if you specifically want the convenience of a sachet.
- Hollandaise insteadSame emulsion, same gluten profile, naturally gluten-free from scratch, and several ready-made hollandaises carry gluten-free labels. Add tarragon and you are most of the way to béarnaise.
- Compound herb butterTarragon, shallot, lemon and butter mashed together and sliced onto hot steak. No emulsion to break, nothing to check.
Avoid by default: any dry sauce sachet: béarnaise, hollandaise, peppercorn, diane, stroganoff. Flour is the standard thickener across that whole shelf.
Related questions
Is hollandaise gluten-free? From scratch, yes: egg yolk, butter, lemon, and no flour. Packet hollandaise mixes have the same wheat-flour problem as the béarnaise mixes, so check the sachet.
Is Knorr béarnaise gluten-free? No. The US mix lists enriched wheat flour and declares wheat on the label.
Is peppercorn sauce gluten-free? Often not. It is usually finished with beef stock or a demi-glace base, and both frequently contain wheat. It is the riskier of the two classic steak sauces.
Can béarnaise ever contain gluten if it's homemade? Only through the vinegar or an add-in. Use white wine vinegar or plain distilled vinegar, not malt vinegar, and you are clear.
What's the difference between béarnaise and hollandaise? The acid and the herb. Hollandaise uses lemon; béarnaise uses a reduced vinegar-shallot-tarragon infusion. Structurally they are the same sauce, which is why they share a gluten answer.
Is béarnaise safe at a steakhouse? Usually. It is nearly always made in-house from butter and yolks. Confirm that the kitchen does not use a powdered base, and pay more attention to the fryer and the bread service.

Overall source tier: C. The "packet mixes contain wheat" half comes from Knorr's own product page, but what that page gives us is an ingredient list and an allergen line, not a manufacturer statement about gluten, and Knorr expressly declines to publish one. A single brand's panel also cannot carry a category verdict on béarnaise; no celiac organisation has ruled on the sauce. The classic-recipe half is a compositional fact about an emulsified sauce. Neither Maille nor Delouis has been confirmed either way. Those remain genuinely unverified and we have not guessed on them.
