Making this casserole is as easy as mixing, layering, and baking. You don’t need advanced cooking skills—as long as you can stir and season, you’re good to go.
Step 1: Cook the Noodles
Prepare your noodles according to package instructions. Drain them slightly undercooked since they will finish cooking in the oven.

Warm your oil or butter in a pan, then add the onions and garlic. Sprinkle in the flour, stirring until it becomes a light paste. Add the broth and milk slowly to create a creamy, light sauce without the need for canned soup.

Mix your cooked noodles, tuna, vegetables, and sauce together until everything is evenly coated. Add salt, pepper, and optional cheese.
Step 4: Transfer to a Baking Dish
Spread the mixture into your casserole dish. If you want an extra crunchy top, sprinkle a bit of whole-wheat breadcrumb and cheese on top.
