How to Make Best Tuna Casserole
Step 1: Preheat the Oven
Preheat your oven to 375°F while preparing the casserole ingredients.
Step 2: Cook the Egg Noodles
Bring a large pot of salted water to a boil. Add the wide egg noodles and cook according to package directions until al dente. Drain well and set aside.
Step 3: Prepare the Sauce Base
In the same large pot, melt 2 tablespoons of unsalted butter over medium heat. Add the chopped yellow onion and cook until softened (about 5 minutes). Stir in the all-purpose flour for about one minute to create a roux.
Step 4: Create Creamy Sauce
Gradually whisk in 2 cups of whole milk until smooth. Bring this mixture to a simmer while stirring constantly until it thickens (about 3-5 minutes). Mix in one can of cream of mushroom soup along with black pepper and garlic powder until fully combined.
Step 5: Combine Ingredients
Remove from heat. Gently fold in cooked egg noodles, drained tuna, and thawed green peas until everything is evenly coated with sauce.
Step 6: Assemble Casserole
Pour this mixture into your prepared baking dish, spreading it evenly across the bottom.
Step 7: Prepare Breadcrumb Topping
In a small bowl, combine panko breadcrumbs with melted unsalted butter. Sprinkle this mixture evenly over your casserole top.
Step 8: Bake
Bake in the preheated oven for 20-25 minutes or until bubbling around edges with a golden brown breadcrumb topping.
Step 9: Serve
Remove from oven and let stand for at least 5 minutes before serving directly from the baking dish. Enjoy your comforting meal!
