Why You’ll Love It

Made from scratch: Flour, milk, and Parmesan combine into a velvety sauce that outshines canned alternatives.
Buttery breadcrumb topping: Crunchy and golden on top, creamy underneath—a classic texture pairing.
Ingredients with Notes and Tips

- Rotini pasta: The spirals catch sauce and tuna well; substitute elbow or penne if needed.
- Canned tuna: Solid white albacore has a firm texture and mild flavor, though regular tuna works too.
- Mushrooms: Baby bella adds a deep, earthy note—sauté first for best flavor.
- Green peas: Frozen peas are convenient and keep their color and texture.
- Butter: Used for sautéing, building the sauce, and coating breadcrumbs for the topping.
- All-purpose flour: Forms the roux; use a gluten-free all-purpose blend if necessary.
- Milk: Whole milk makes a richer sauce; 2% is a lighter but suitable option.
- Parmesan cheese: Freshly grated for the best flavor; cheddar can be used if preferred.
- Breadcrumbs: Regular or gluten-free, tossed with melted butter for a crisp finish.
- Seasonings: Dried thyme, garlic powder, onion powder, salt, and black pepper keep the flavor simple and familiar.
Ingredient Substitutions and Additions
Easy swaps and additions to customize the casserole:
- Pasta: Elbow macaroni or penne substitute nicely for rotini.
- Flour: Gluten-free all-purpose flour works; results vary by brand.
- Mushrooms: Use jarred mushrooms (drained) if fresh aren’t available.
- Vegetables: Replace peas with mixed vegetables for more variety.
- Topping: Crushed crackers or potato chips make a tasty, crunchy alternative to breadcrumbs.
- Protein swap: Canned salmon can be used instead of tuna—drain, remove skin and bones, and flake.
- Add-ins: Fold in cooked bacon or cooked shrimp to make the dish heartier.
How to Make Tuna Noodle Casserole (No Soup)
A straightforward, old-school comfort casserole that’s quick to assemble.

Step 1: Sauté mushrooms with seasonings in butter until tender; transfer to a bowl.

Make Ahead Friendly
This casserole can be prepared 1–2 days in advance (leave the breadcrumb topping off). Store covered in the refrigerator. When ready to bake, add the buttered breadcrumbs and bake; allow an additional 15–20 minutes if baking from chilled.
Make it a Freezer Meal
Assemble the casserole without baking, wrap it tightly, and freeze. Thaw overnight in the refrigerator before baking as directed.
Side Dish Suggestions
The casserole is filling on its own, but these sides pair nicely:
- Tomato soup or a simple green salad for a light contrast.
- Creamy corn salad or a buttered vegetable side for added comfort.
- Roasted Brussels sprouts or roasted vegetables to boost vegetables on the plate.
Cooking and Serving Tips
- Cook pasta al dente to prevent it from becoming mushy after baking.
- Bake in smaller individual dishes for single servings; reduce baking time accordingly.
- Keep the casserole warm in the oven set to low and covered with foil to retain moisture.
- When reheating, add a splash of milk or broth to restore creaminess if it has dried out.
