Ingredients
Method
- Preheat the oven to 350 degrees then spray an 8×8” baking dish with nonstick spray and set aside.
- Heat the extra virgin olive oil in a medium-sized saucepan or skillet over medium-high heat then add the mushrooms and shallots. Saute until the mushrooms release their liquid, the liquid cooks off, and the mushrooms become tender, 5-7 minutes. Scrape the mushroom and shallot mixture into a bowl then set aside.
- Lower the heat to medium then melt the butter inside the pan. Sprinkle in the flour then cook while whisking for 1 minute. Slowly add the chicken broth while whisking to create a smooth sauce then add the milk and seasonings. Turn the heat up to medium-high then cook while stirring until the soup is fairly thick, 3-4 minutes, turning the heat down if needed to prevent splattering. Turn off the heat then add the cooked mushrooms to the pan and stir to combine.
- Remove a heaping 1/2 cup prepared cream of mushroom soup for another use (or eat — it’s delicious as-is!) then scrape the remaining soup into a large mixing bowl and set it aside to cool slightly. The soup can be made up to 3 days ahead of time.
- Bring a large pot of generously salted water to a boil then add the pasta and cook until it’s just a touch under al dente — don’t overcook as the pasta will continue to soften in the oven. Drain then add the pasta to the mixing bowl with the slightly cooled cream of mushroom soup.
- Add the flaked tuna, frozen peas, and pepper to the mixing bowl then stir to combine. Scoop the mixture into the prepared baking dish then top with the shredded cheese and crushed potato chips. Bake for 15-20 minutes or until the sauce is bubbly, cheese has melted, and potato chips are golden brown. Let the casserole cool for 5-10 minutes before scooping into bowls and serving.
Notes
– When cooking the gluten-free pasta, aim for just under al dente. It will continue to cook and soften in the oven, preventing it from becoming mushy.
– Make-ahead magic: The mushroom soup base can be prepared up to 3 days in advance and stored in the refrigerator, making dinner prep even faster. Nutrition information is an estimate, calculated automatically. Values vary with brands, substitutions and portion sizes.
The technique that makes it
The success of this gluten-free tuna noodle casserole hinges on creating a rich, creamy, and cohesive sauce that coats the pasta without becoming watery or greasy. This is primarily achieved through careful management of the roux and the incorporation of cheese. The initial sauté of shallots and mushrooms builds a flavor base and adds moisture. The key step is the roux: melting butter and then whisking in the gluten-free pasta water (or a bit of milk if you prefer a richer sauce) to create a thickened liquid. This is not a traditional flour roux, but rather a starch-thickened sauce. The gluten-free pasta, when cooked al dente, will absorb some of this liquid. Crucially, the cheese must be incorporated off the heat or at very low heat. Adding shredded cheese directly to a boiling sauce can cause the proteins to seize, resulting in a greasy, separated, and grainy texture. Stirring gently until the cheese is melted creates a smooth, emulsified sauce. The final addition of flaked tuna and peas should be done gently to avoid breaking up the tuna too much. The potato chip topping provides a textural contrast and a salty, savory crunch, which is essential to elevate this simple casserole.
Troubleshooting
- Problem: Casserole is watery. Fix: Ensure pasta is cooked al dente and not overcooked, as it will absorb more liquid. Also, make sure mushrooms are sautéed until their liquid has evaporated. Avoid adding too much extra liquid to the sauce.
- Problem: Sauce is greasy or separated. Fix: This usually happens when cheese is added to a sauce that is too hot. Remove the sauce from the heat before stirring in the shredded cheddar cheese. Stir gently until just melted.
- Problem: Casserole is bland. Fix: Ensure you are using good quality tuna. Sautéing the shallots and mushrooms properly builds flavor. Don’t skimp on the black pepper, and consider adding a pinch of garlic powder or a dash of Worcestershire sauce (if not strictly gluten-free) to the sauce for more depth.
- Problem: Gluten-free pasta is mushy. Fix: Cook the gluten-free pasta strictly according to package directions, aiming for al dente. Gluten-free pastas can break down easily if overcooked. Reserve pasta water before draining.
Substitutions
- Pasta: Any short gluten-free pasta shape like penne or elbows can be used. The texture might vary slightly, but the casserole will still be delicious.
- Tuna: Canned salmon or shredded cooked chicken can be substituted for tuna. Ensure they are well-drained and flaked. The flavor profile will change but remain complementary.
- Cheese: Monterey Jack, Gruyere, or a dairy-free shredded cheese blend can replace cheddar. Each will impart a slightly different flavor and meltability.
- Potato Chips: Crushed gluten-free crackers (like rice crackers) or toasted breadcrumbs can be used for the topping. This will offer a different crunch and flavor.
Pro tips
- For the creamiest sauce, ensure your roux cooks for at least 1 minute after adding flour to eliminate any raw flour taste.
- When cooking the gluten-free pasta, aim for just under al dente. It will continue to cook and soften in the oven, preventing it from becoming mushy.
- Make-ahead magic: The mushroom soup base can be prepared up to 3 days in advance and stored in the refrigerator, making dinner prep even faster.

Frequently asked questions
Can I make this tuna noodle casserole ahead of time?
Yes, you can assemble the casserole up to the point of adding the potato chip topping and refrigerate it for up to 24 hours. Bake as directed, adding the chips during the last 10-15 minutes of baking to ensure they stay crisp.
What kind of gluten-free pasta works best?
Gluten-free rotini or fusilli, especially those made from brown rice, are recommended because their shape holds the creamy sauce well. Cook them strictly al dente, as they can become mushy if overcooked.
How do I prevent the sauce from being greasy?
The key is to remove the casserole from direct heat before stirring in the shredded cheddar cheese. Stirring gently until the cheese is just melted will create a smooth, emulsified sauce without separation.
Can I add other vegetables to this casserole?
Certainly. Sautéed onions, carrots, or celery can be added with the mushrooms. Frozen corn or green beans can also be stirred in with the peas for added flavor and nutrition.
