Ingredients

Scale

Main Ingredients

1 (12 ounce) package egg noodles
2 (10.5 ounce) cans condensed cream of mushroom soup
2 cups shredded Cheddar cheese, divided
2 (5 ounce) cans tuna, drained
1 cup frozen green peas
½ (4.5 ounce) can sliced mushrooms
¼ cup chopped onion
1 cup crushed potato chips

Instructions

Cook the noodles: Fill a large pot with lightly salted water and bring to a boil. Add the egg noodles and cook until tender yet firm to the bite, approximately 7 to 9 minutes. Drain the noodles thoroughly.
Preheat the oven: While the noodles cook, preheat your oven to 425 degrees F (220 degrees C) to ensure it’s ready for baking.
Mix the casserole ingredients: In a large bowl, combine the cooked noodles, both cans of condensed cream of mushroom soup, 1 cup of shredded Cheddar cheese, drained tuna, frozen peas, sliced mushrooms, and chopped onion. Stir gently until all ingredients are evenly coated and mixed well.
Transfer to baking dish: Pour and spread the mixture evenly into a 9×13-inch baking dish.
Add toppings: Sprinkle the crushed potato chips evenly over the casserole, then top with the remaining 1 cup of shredded Cheddar cheese for a crunchy and cheesy crust.
Bake: Place the casserole in the preheated oven and bake for about 15 to 20 minutes, or until the cheese is melted, bubbly, and the edges turn lightly golden brown.
Serve: Remove from oven and serve hot. Enjoy this comforting and hearty tuna casserole!

Notes

For an alternative crunchy topping, try crushed butter crackers, cornflakes, or French-fried onions instead of potato chips.
This casserole pairs wonderfully with roasted Brussels sprouts, steamed broccoli, or green beans for a complete meal.
You can assemble the casserole the day before, cover, and store it in the refrigerator overnight—just bake it fresh before serving.
Store leftovers in an airtight container in the refrigerator for up to four days and reheat in the oven or microwave.
To freeze, prepare in a foil pan, cool completely, wrap tightly with plastic wrap and foil, and freeze for up to three months. Thaw overnight in the fridge before reheating.
