Is Cream of Mushroom Soup Gluten Free? (Brand by Brand, 2026)

Add as Google Trusted Source

Cream of mushroom soup is in half the casseroles I grew up on, so this is one of the first things people ask when they go gluten free. The classic red and white can is not gluten free. But there are good gluten free versions now, and I went through each brand's own label so you know exactly which can to grab.

🍽️ The quick answer

Regular cream of mushroom soup is usually not gluten free. Campbell's classic condensed version is thickened with wheat flour. But Campbell's now makes a Gluten Free Cream of Mushroom that uses rice flour instead, and Pacific Foods Organic Cream of Mushroom is also labeled gluten free. Checked against each brand's own product pages on 26 September 2026. Here's the full breakdown.

🥫 Why most cream of mushroom soup has gluten

Condensed cream soups need to be thick, and the cheapest, most traditional way to thicken them is wheat flour. It's the same idea as making a roux for gravy. So the classic can lists wheat flour right there in the ingredients, a few spots after the mushrooms.

The gluten free versions swap that wheat flour for rice flour, cornstarch, or modified food starch. The soup still thickens, it still works in a casserole, and there's no wheat in it.

Brand by brand

Campbell's Condensed Cream of Mushroom (classic red and white can)

Not gluten free. The ingredients are water, mushrooms, vegetable oil, modified cornstarch, wheat flour, salt, cream, whey, soy protein concentrate, MSG, yeast extract, dried garlic, and natural flavoring. It says "Contains: Wheat, Milk, Soy."

Campbell's 98% Fat Free Cream of Mushroom

Not gluten free. It's also made with wheat flour and says "Contains: Wheat, Milk, Soy."

Campbell's 25% Less Sodium Cream of Mushroom

Not gluten free. Wheat flour again, and "Contains: Wheat, Milk, Soy."

Campbell's Condensed Gluten Free Cream of Mushroom

Gluten free. This is the one you want if you're following a recipe that calls for a can of Campbell's. It's the same 10.5 oz condensed size, so it's a perfect swap. The ingredients are water, mushrooms, vegetable oil, modified cornstarch and rice flour, plus less than 2% of cream, salt, whey, yeast extract, soy protein concentrate, natural flavoring, dried garlic, and spice. It says "Contains: Milk, Soy."

Campbell's says it checks every ingredient first and then tests the finished soup to make sure it meets the FDA's gluten free standard, and keeps testing it over time. There's a Gluten Free Cream of Chicken in the same line too.

Pacific Foods Organic Cream of Mushroom Condensed Soup

Gluten free. Pacific labels it gluten free, and the ingredient list is short: water, mushrooms, cream, cornstarch, rice flour, sea salt, garlic powder, and onion powder. It's organic and "Contains: Milk." This is my pick if you want the simplest label on the shelf. I often use their products.

Progresso Vegetable Classics Creamy Mushroom

Gluten free, but it isn't condensed. Progresso describes it as vegetarian and gluten free. It's made with portobello mushrooms and thickened with modified food starch, and it contains milk and soy. It's a ready-to-eat soup, so it's great in a bowl, but it's thinner than condensed soup and won't behave the same way in a casserole.

Progresso Traditional Creamy Chicken Mushroom with Barley

Not gluten free. Barley contains gluten, and it's right there in the name.

Store brands (Great Value, Kroger, Good and Gather and the rest)

Check the can every time. Most store-brand condensed cream of mushroom soups are made the traditional way with wheat flour. A few stores carry a gluten free version, but I haven't checked them here, so read the label.

Tips

"Cream of mushroom" and "creamy mushroom" aren't the same product. Condensed cream of mushroom is the thick stuff you add to casseroles. Creamy mushroom soup, like the Progresso one, is ready to eat and much thinner. If your recipe says "one can of condensed cream of mushroom soup," a ready-to-eat soup will make it runny.

And watch out for green bean casserole kits and frozen casseroles. Even if the soup inside is fine, the crispy fried onions on top almost always contain wheat.

How to Check Any Can in 10 Seconds

If you're standing in the soup aisle with a brand that isn't on this list, here's what I look for:

1. Look for the words "gluten free" on the front or back. In the US, that means the soup has to meet the FDA's limit of under 20 parts per million of gluten.
2. Read the "Contains" line. If it says wheat, put it back.
3. Scan the ingredients for wheat flour, barley, malt, or rye. Barley and malt don't have to show up in the "Contains" line, so this step matters.
4. If there's no gluten free claim and nothing obvious in the ingredients, I'd still be careful. Without the label, the brand isn't promising anything about cross-contact in the factory.

Brands change recipes without much fanfare, so check again even on a can you've bought before.

Make Your Own Gluten Free Cream of Mushroom

If you can't find a gluten free can, homemade is easy and takes about 10 minutes. This makes about the same amount as one 10.5 oz can.

1. Melt 2 tablespoons butter in a small pan and cook 1 cup finely chopped mushrooms until soft.
2. Stir in 2 tablespoons of sweet rice flour or your favorite gluten free flour blend and cook for a minute.
3. Slowly whisk in ½ cup of gluten free chicken or vegetable broth and ½ cup of milk.
4. Keep stirring until it's thick, then season with salt, pepper, and a pinch of garlic powder.

Use it anywhere a recipe calls for one can of condensed soup.

Where to use it

Casserole season is coming, and this one can is the backbone of so many of them. My gluten free Thanksgiving roundup has plenty of ideas, and my gluten free sweet potato casserole and gluten free corn casserole are on our table every year. If you're after the chicken version too, I've got a whole list of Campbell's cream of chicken soup recipes. Just swap in the gluten free can.
