Plain feta cheese is naturally gluten-free — milk, salt, and enzymes, with no wheat, barley, rye, or oats.
Yes. Athenos, President, and most US-distributed feta brands are labeled gluten-free, and the underlying recipe is naturally gluten-free across all real feta. The risks are at the deli counter (shared slicers, cross-contact with bread), in flavored or marinated variants (added breadcrumbs, croutons, wheat-based seasonings), and in restaurants that serve feta alongside pita.
Feta is one of the easiest cheeses on a gluten-free diet — when you buy it pre-packaged from a sealed brick or crumble. The real-world risks aren’t with the cheese itself; they’re with the salad bar, the deli slicer, and the “Mediterranean blend” tub that’s mostly feta but with mystery seasonings added. This article covers what to look for and where to skip.
Why Plain Feta Is Gluten-Free
Real feta is made from sheep’s milk or a sheep-and-goat-milk blend, cultured with bacteria and coagulated with enzymes (microbial rennet or animal rennet), then salt-brined. US-made “feta” is often made from cow’s milk and follows the same simple recipe. Either way: milk, salt, enzymes. None of those is on the FDA’s gluten-containing grain list (21 CFR 101.91).
Athenos — the most common US feta brand, owned by Kraft Heinz — publishes its full ingredient list and is labeled gluten-free across the Traditional, Reduced Fat, and Crumbled product lines. The crumbled variants add two ingredients: powdered cellulose (an anti-caking agent derived from wood pulp, not wheat) and natamycin (a natural antifungal preservative). Both are gluten-free.
Where the Real Risk Is
Feta itself is fine. Three places things go wrong:
1. Deli Counter Slicers and Crumblers
If you buy feta from a deli case where the staff cuts a brick to order, the slicing equipment may have been used on bread, wheat-coated meats, or other gluten-containing products earlier in the day. For severely sensitive celiacs, ask for a sealed pre-packaged feta brick instead of a deli-counter cut, or ask the deli staff to clean the slicer and use a fresh cutting board.
2. Flavored and Marinated Variants
“Mediterranean feta in olive oil” tubs frequently include sun-dried tomatoes, capers, olives, and herbs — none of which are inherently a gluten problem. But some brands include croutons (definitely not GF), breadcrumb-coated seasonings, or “Mediterranean spice blends” that aren’t broken out on the front label. Always read the full ingredient list on flavored, marinated, or “blend” feta products.
3. Restaurants — Especially Greek
Feta in a Greek restaurant comes with risks the cheese itself doesn’t create: pita bread served alongside, shared utensils between the feta and gluten-containing dishes, and salad dressings (some Greek dressings use wheat-based thickeners or soy sauce). Order the feta plain, ask about the dressing, and skip the pita basket or have it removed entirely so crumbs don’t migrate.
Cross-Contamination Risk
Manufacturing
Low
- Plain feta is a simple cheese — milk, salt, enzymes; no gluten ingredients.
- Athenos and several other major US brands are labeled gluten-free at the FDA <20 ppm threshold.
- Anti-caking agents in pre-crumbled feta (typically powdered cellulose) are wood-pulp-derived and gluten-free.
Restaurant / Deli
Medium
- Deli slicers and shared utensils can transfer gluten from bread and wheat-coated meats.
- Greek restaurants serve feta with pita; ask the kitchen to omit the bread and use clean prep surfaces.
- Salad bars with feta in an open container near croutons or pasta salad carry cross-contact risk.
Home
Low
- Sealed package; standard refrigerator storage.
- Use a clean spoon or tongs; avoid cross-contact with bread, crackers, or wheat-pasta dishes.
What to Look For on the Package
- “Gluten Free” label on the package (Athenos, President, and most US-distributed feta brands)
- Simple ingredient list — milk, salt, enzymes, and (for crumbled) powdered cellulose + natamycin
- “Contains: Milk” allergen statement — expected, since milk is the primary ingredient
- PDO (Protected Designation of Origin) Greek feta — same recipe, sometimes more expensive, equally gluten-free
- “Mediterranean blend,” “Greek salad mix,” or “feta with herbs” — read every ingredient; added components may not be GF
- “Feta-style crumbles” or “feta blend” — may be a mix of cheeses with different ingredient profiles
- Deli-counter feta cut on a shared slicer — cross-contact risk from previous cuts
Frequently Asked Questions
Is feta cheese gluten-free?
Yes. Plain feta cheese is naturally gluten-free — the recipe is milk, salt, and enzymes, with no wheat, barley, rye, or oats. Athenos, President, and most US-distributed feta brands are labeled gluten-free. Risks are at deli counters (shared slicers), in flavored or marinated variants (added breadcrumbs, croutons, or wheat-based seasonings), and at Greek restaurants (pita bread cross-contact).
Is Athenos feta gluten-free?
Yes. Athenos Traditional Feta and Athenos Crumbled Feta are labeled gluten-free. Ingredients are cultured pasteurized milk, salt, and enzymes, with powdered cellulose anti-caking agent and natamycin natural mold inhibitor on the crumbled variants. Athenos Traditional Feta is documented as free from all 14 top international allergens including wheat, barley, rye, and oats.
Is crumbled feta gluten-free?
Yes. Crumbled feta adds two ingredients to plain feta: powdered cellulose (a wood-pulp anti-caking agent) and natamycin (a natural antifungal preservative). Both are gluten-free. The “powdered cellulose” wording sometimes worries celiac readers but it has no wheat or gluten connection.
Is feta in a Greek salad gluten-free?
The feta itself is gluten-free. The salad as a whole depends on the dressing and any add-ins. Standard Greek dressing (olive oil, red wine vinegar, oregano, salt) is gluten-free; bottled Greek dressings sometimes use wheat-based thickeners or modified food starch — read the label. Croutons obviously are not GF and should be omitted. At Greek restaurants, ask about the dressing and skip the pita basket.
Is flavored or marinated feta gluten-free?
It depends on the flavoring. Pure olive oil, sun-dried tomatoes, olives, and herbs are gluten-free. But some “Mediterranean feta” tubs include croutons, breadcrumb-coated seasoning blends, or proprietary spice mixes with hidden gluten. Always read the full ingredient list on any flavored or marinated feta — the cheese is fine, but what’s been added to it may not be.
Can celiacs eat deli-counter feta?
The cheese itself is gluten-free, but deli slicers and prep surfaces often have been used on bread, wheat-coated meats, or gluten-containing cheese spreads earlier in the day. For severely sensitive celiacs, ask for a sealed pre-packaged feta brick from the dairy aisle instead of a deli-counter cut. If you must use the deli counter, ask the staff to clean the slicer and use fresh cutting paper.
