This wonderful tuna noodle casserole is made with a rich and creamy homemade sauce, noodles, and just 1 can of tuna. It's the ultimate single serving comfort food!

When I was growing up, tuna casserole was a meal my mom made often. It was simple, inexpensive, and it was a meal my mom could make quickly.

Why I Love This Recipe
My mother's version of tuna casserole was made with canned tuna, canned cream of mushroom soup and noodles.
My version of tuna casserole is just as easy but I don't use canned soup. Instead I make a creamy sauce which is a buttery blend of onions, cream, milk, nutmeg, garlic powder and thyme.
The sauce takes just minutes to make and tastes incredible. So worth the extra few minutes of stirring on the stove. It's creamy, savory, and cheesy.
This mini tuna casserole has all the flavors I've always loved in a tuna casserole, including a crisp buttery topping.

Ingredient Notes
See recipe box below for ingredient amounts and full recipe instructions.
- Pasta: I use 1/2 cup of dried elbow macaroni in this tuna casserole recipe. When cooked, this amount yields 1 cup of cooked pasta.
- Butter: Salted butter is used to cook the onions in and to help to make the roux for the sauce. You will also use a little melted butter for the tuna casserole topping.
- Onions: Use 1/4 cup of chopped onions.
- Flour: Use all-purpose flour to thicken the sauce.
- Seasonings: Dried thyme, garlic powder, nutmeg, salt and black pepper.
- Milk: Use any percentage of cow's milk.
- Heavy cream: This ingredient helps to thicken the sauce and makes it extra rich.
- Lemon juice: You can use either freshly squeezed or bottled lemon juice.
- Cheese: For best results, use freshly shredded cheddar cheese and freshly grated Parmesan cheese.
- Canned tuna: Be sure to drain the water or oil from the can of tuna.
- Breadcrumbs: Use store-bought or homemade breadcrumbs for the topping.
