Quick Answer
Most store bought polenta is gluten-free, but it’s important to check the label. Polenta is made from cornmeal, which does not naturally contain gluten. However, some brands may add wheat or other gluten-containing ingredients. Look for labels that specify the product is gluten-free or made with 100% corn. When in doubt, contact the manufacturer to inquire about potential cross-contamination. Those with celiac disease or gluten sensitivity should exercise caution when selecting store bought polenta.
What is Polenta?
Polenta is a popular Italian dish made from coarsely ground cornmeal. It has a creamy, porridge-like texture and mild, nutty flavor. Polenta can be served soft and mushy, or allowed to cool and solidify into slices that can be fried, grilled, baked, or sautéed.
Traditional polenta is made by mixing cornmeal (usually a coarse grind) with water or broth in a pot. It’s stirred frequently and simmered until thickened and tender, then topped with sauce, cheese, or other ingredients. Pre-made instant or quick polenta mixes are widely available in grocery stores for convenience.
Polenta has been a staple of Northern Italian cuisine for centuries. It was historically made from a variety of locally grown grains before corn was introduced to Europe after 1492. Cornmeal became popular for polenta in the 17th and 18th centuries because it was inexpensive and yielded a substantial dish. Today, polenta remains a rustic comfort food in Italy and beyond.
Is Polenta Typically Gluten-Free?
Polenta made from 100% cornmeal without added ingredients is inherently gluten-free. Corn naturally does not contain gluten.
Gluten is a group of proteins found in grains like wheat, barley, and rye. People with celiac disease or non-celiac gluten sensitivity cannot tolerate gluten and experience digestive issues or other adverse symptoms after eating it. Those with gluten-related disorders must follow a strict lifelong gluten-free diet.
Since corn and cornmeal do not naturally contain gluten, plain polenta is considered a gluten-free food. This makes it a safe, staple carb option for those avoiding gluten. Many traditional recipes for polenta simply call for cornmeal, water or broth, and salt.
However, some pre-made polenta mixes and ready-to-eat polenta products available commercially may include other ingredients that can introduce gluten.
Risk of Cross-Contamination
Even if the ingredients look gluten-free, there is still a risk of cross-contamination during processing and manufacturing.
Cross-contamination occurs when a gluten-free food comes into contact with a food containing gluten during production or preparation. This transfers trace amounts of gluten into the gluten-free food, which is problematic for those highly sensitive.
Some potential sources of cross-contamination include:
- Shared equipment – Polenta produced on equipment also used for wheat-based foods
- Shared facilities – Polenta processed or packaged in a facility that also handles gluten products
- Ingredients – Additives or seasonings that contain gluten
Due to the risk of cross-contamination, some polenta brands may not be suitable for a gluten-free diet even if the cornmeal itself is gluten-free. Checking labels carefully and contacting manufacturers is important.
Reading Labels on Store Bought Polenta
When purchasing pre-made polenta from grocery stores, check the label closely for any mention of gluten or wheat-based ingredients:
- Look for a “gluten-free” label – This indicates the product has been tested to verify gluten levels below 20 ppm, the cutoff for gluten-free certification.
- Check the ingredients – They should just list “cornmeal” without wheat, barley, rye or ambiguous ingredients like “starch.”
- Beware of seasonings – Added flavorings or spice blends may contain gluten.
- Look for possible cross-contamination – An “Processed in a facility…” statement indicates risk.
Call or email the manufacturer if you have any concerns. They should be able to verify whether their polenta is safe for a gluten-free diet.
It’s also advisable to check labels each time you buy, even for a product you’ve purchased before. Manufacturers can occasionally change ingredients or processes without notice.
Polenta Label Examples
Here are examples of what to look for on polenta packaging:
Gluten-Free Claim:
Organic Yellow Corn Polenta – Gluten-Free
Ingredients List:
Ingredients: organic yellow cornmeal.
Contains Statement:
Contains corn. Manufactured in a dedicated gluten-free facility.
Ambiguous Label:
Ingredients: cornmeal, modified food starch, spice.
No gluten-free claim and vague “spice” makes this risky.
Additional Tips for Purchasing Polenta
Here are some other tips when evaluating store bought polenta:
- Opt for plain polenta rather than flavored varieties.
- Look for brands certified gluten-free by an independent agency like GFCO.
- Purchase brands made in dedicated gluten-free facilities when possible.
- Call the company to ask about testing and quality control measures.
- Stick to reputable brands known to cater to gluten-free diets.
- Check polenta that is imported from Europe for gluten-containing additives.
Purchasing plain, organic polenta from brands certified gluten-free generally provides the greatest level of assurance. But always verify by carefully reading the label each time.
Is Restaurant or Homemade Polenta Gluten-Free?
Dining out and homemade polenta require additional precautions compared to packaged brands.
In restaurants, risk of cross-contamination from shared kitchen equipment is high. Servers should be informed of dietary needs so proper precautions can be taken. Ensure restaurants do not add gluten-containing ingredients to polenta.
When making homemade polenta, look for cornmeal that’s certified gluten-free. Be aware that some specialty cornmeal varieties, like blue cornmeal, may be produced by smaller mills and carry higher risk. Only use dedicated gluten-free cooking equipment and preparation areas.
Safe Gluten-Free Polenta Brands
Here are some recommended brands of store bought polenta that are labeled gluten-free:
- Bob’s Red Mill Corn Grits Polenta
- Arrowhead Mills Organic Polenta Corn Grits
- Belvedere Organic Yellow Polenta Corn Meal
- Roland Foods Polenta
- DeLallo Organic Polenta
- Viana Organic Polenta
- Filotea Quick Polenta
- Anson Mills Organic Polenta
Always confirm the product you’re purchasing is certified gluten-free and produced in a gluten-free facility. Ingredients and manufacturing processes can vary across different varieties, even within the same brand. Check each time you buy.
When in doubt, choose another known gluten-free whole grain like quinoa, brown rice, certified gluten-free oats, or millet instead of taking a risk with polenta.
Is Polenta on a Gluten-Free Diet?
Most people following a strict gluten-free diet can eat polenta made with simple cornmeal and prepared properly to prevent cross-contamination. But some extra diligence is required when purchasing store bought varieties.
Those with celiac disease or wheat allergy should be especially cautious, as even small amounts of gluten can cause issues. Individual tolerance levels vary.
Some additional tips for eating polenta gluten-free:
- Closely inspect labels of any pre-made polenta products.
- Call manufacturers with any questions or concerns about ingredients or production.
- Choose certified gluten-free brands manufactured in dedicated facilities when possible.
- Opt for plain cornmeal polenta without flavorings or add-ins.
- Make homemade polenta using certified gluten-free cornmeal.
- Ensure restaurants understand dietary needs to avoid cross-contamination.
With proper precautions, most people avoiding gluten can enjoy polenta as a satisfying gluten-free grain option. But take care to carefully check all labels and potential sources of contamination. When in doubt, leave it out.
Cooking Gluten-Free Polenta
It’s easy to prepare homemade gluten-free polenta using just a few simple ingredients:
Ingredients
- 1 cup gluten-free cornmeal or polenta
- 3-4 cups water, broth, or non-dairy milk
- 1/2 teaspoon salt
- Optional seasonings like garlic, pepper, cheese
Instructions
1. Bring the liquid to a boil in a heavy saucepan. Slowly whisk in the cornmeal.
2. Reduce heat to low and cook, stirring frequently, until thickened, about 15-20 minutes.
3. Stir in any additional seasonings and cook 2-3 more minutes.
4. For firmer polenta, pour into a greased pan and refrigerate until set. Then slice and pan fry or grill.
5. For soft polenta, serve immediately topped with your favorite gluten-free sauce or toppings. Enjoy!
Be sure to use gluten-free certified cornmeal and cookware. Polenta firms up more as it cools. Leftovers can be refrigerated up to 5 days or frozen.

- B Vitamins – Important for converting food into energy and supporting nervous system function.
- Iron – Carries oxygen in the blood to cells and tissues.
