Essential Ingredients
Casserole Base:
- ½ cup butter, divided

- ½ medium onion, finely chopped
- 1 stalk celery, finely chopped
- 1 clove garlic, minced
- 8 ounces button mushrooms, sliced
- ¼ cup all-purpose flour
- 2 cups milk
- Salt and pepper to taste
- 2 (5-ounce) cans tuna, drained and flaked
- 1 cup frozen peas, thawed
Topping:
- 3 tablespoons bread crumbs
- 1 cup shredded Cheddar cheese
Preparation Steps
- Preheat & Prepare: Preheat the oven to 375°F (190°C). Butter a medium baking dish with 1 tablespoon of butter.
- Cook the Noodles: Boil a large pot of salted water and cook egg noodles until tender yet firm to the bite (7-9 minutes). Drain and set aside.
- Sauté the Vegetables: Melt 1 tablespoon of butter in a skillet over medium-low heat. Add onion, celery, and garlic, cooking until tender (about 5 minutes). Increase heat to medium-high, add mushrooms, and cook until most of the liquid evaporates (about 5 more minutes). Set aside.
- Make the Sauce: In a medium saucepan, melt 4 tablespoons of butter. Whisk in flour until smooth. Gradually add milk, whisking constantly, and cook until the sauce thickens (about 5 minutes). Season with salt and pepper.
- Combine the Ingredients: Stir in tuna, peas, mushroom mixture, and cooked noodles into the sauce. Mix well and transfer to the prepared baking dish.
- Prepare the Topping: Melt the remaining 2 tablespoons of butter and mix with bread crumbs. Sprinkle over the casserole, then top with shredded Cheddar cheese.
- Bake & Serve: Bake for 25 minutes, or until bubbly and lightly browned on top. Serve hot and enjoy!
