What You Need for a Tuna Casserole with Few Ingredients

You only need four ingredients to make this comforting 4-ingredient tuna casserole, but you can easily customize it with what you have on hand. Here’s what you’ll need to get started:

Ingredient	Notes
Canned tuna	Drained – water or oil-packed both work
Condensed cream of mushroom soup	Adds creamy texture and umami flavor
Cooked pasta	Elbow macaroni or rotini are great choices
Shredded cheese	Cheddar is classic, but mozzarella or Monterey Jack work too

Optional Add-Ons for Extra Flavor:

These additions are entirely optional but can elevate your tuna casserole to new heights:

Topping ideas: crushed Ritz crackers, French fried onions, panko breadcrumbs with melted butter

½ cup frozen peas or corn

¼ teaspoon garlic powder or onion powder

1 tablespoon mayonnaise or sour cream for added creaminess

How to Make This Fast Tuna Casserole Step by Step

Making this 4-ingredient tuna casserole couldn’t be easier. With just a few steps, you’ll have a hot, bubbly dish ready for the dinner table.

1. Preheat your oven to 375°F (190°C). Lightly grease an 8×8 or 9×13-inch baking dish, depending on how thick you prefer your casserole.
2. In a large mixing bowl, combine the cooked pasta, drained tuna, cream of mushroom soup, and shredded cheese. Stir until everything is well mixed.
3. Pour the mixture into the prepared baking dish and spread evenly with a spatula.
4. If you’re adding a topping (like breadcrumbs, crushed crackers, or fried onions), sprinkle it over the top now.
5. Bake for 25–30 minutes, or until the casserole is hot and bubbly and any topping is golden brown.
6. Let it cool for about 5 minutes before serving. This helps it firm up and makes scooping easier.

Additional Cooking Tips:

If your casserole looks dry after baking, add a splash of milk or a spoonful of sour cream before reheating.

For a crispier top, broil for the last 2–3 minutes—but keep a close eye to avoid burning.
