How Do You Make Classic Tuna Casserole Recipe?
Step 1: Cook the Noodles
Bring a large pot of salted water to a boil. Cook egg noodles according to package instructions until just al dente. Drain and set aside.
Step 2: Sauté the Onion
In a skillet over medium heat, melt the butter. Add diced onion and cook for 3–4 minutes until soft and fragrant.
Step 3: Make the Creamy Base
In a large bowl, combine cream of mushroom soup, milk, garlic powder, salt, and black pepper. Stir until smooth.
Step 4: Combine the Filling
Add cooked noodles, tuna, sautéed onion, peas, and shredded cheese to the sauce. Gently fold until evenly coated.
Step 5: Assemble the Casserole
Preheat oven to 375°F (190°C). Transfer mixture to a greased baking dish and spread evenly.
Step 6: Add the Topping
Mix breadcrumbs with olive oil or melted butter. Sprinkle evenly over the casserole.
Step 7: Bake Until Golden
Bake uncovered for 25–30 minutes, until bubbly and lightly golden on top. Let rest 5 minutes before serving.
Common Mistakes to Avoid
- Overcooking the noodles – They will soften more in the oven.
- Skipping seasoning – Tuna and pasta need proper seasoning.
- Using dry tuna – Always drain well, but don’t squeeze dry.
- Too little sauce – The casserole should look creamy before baking.
- Overbaking – This can dry out the dish quickly.
Serving Suggestions
- Simple green salad with vinaigrette
- Steamed broccoli or green beans
- Garlic bread or dinner rolls
