Old Fashioned Tuna Casserole (2024)

Old Fashioned Tuna Casserole: A delicious dish of a tuna mixture with cream of mushroom soup, cheese, and a few other simple ingredients baked in a baking dish. Casserole recipes are perfect for an easy dinner, for a potluck or to take in a meal care package for someone.

Tuna is so versatile and can be used in so many dishes, warm or cold. We’ve used it in a tuna pasta salad, and in this tuna salad recipe, and they’ve both been extremely popular recipes, so I knew you’d love this old fashioned tuna noodle casserole too.

🧾 Ingredients for Tuna Casserole

You’ll need the following for this old-fashioned tuna casserole:

• 4 Tablespoons Butter, Melted
• 2 Tablespoons Pimento Peppers (optional)
• 1 Teaspoon Onion Powder
• ½ Teaspoon Salt
• ½ Teaspoon Pepper
• 2 – 15.5oz Cans Cream of Mushroom

👩🏻‍🍳 How to Make Tuna Casserole

*Be sure to see the recipe card below for the full ingredients list & instructions!*

1. Preheat the oven to 425 degrees and spray a 9 x 13 casserole dish with cooking spray.

2. In a large mixing bowl stir together tuna, melted butter, pimento peppers, onion powder, salt, and pepper.

3. Then add the cans of soup, sour cream, peas and carrots, cheese, and milk to the bowl. Mix well.

4. Finally add the cooked noodles to the bowl and fold into the mixture.

Tip: Make sure the cooked noodles are cooked until al dente. If cooked too much, they’ll be mushy after baking in the oven.

5. Spread the mixture evenly in the casserole dish.
6. Sprinkle fried onions over the top.
7. Bake in the preheated oven for 15-20 minutes until warm all the way through and golden brown.
