This Timeless Tuna Casserole is the epitome of comfort food, perfect for a cozy family dinner. It's straightforward to make, packed with flavor, and has a crunchy, cheesy topping that's hard to resist.
This dish begins with egg noodles, which provide a sturdy base and soak up all the delicious flavors. Butter is used for sautéing the vegetables, giving them a rich flavor. When it comes to veggies, we've got onion, garlic, and celery, which together create a savory base. Frozen peas add a pop of color and sweetness, making the dish more vibrant.
The creamy component comes from cream of mushroom soup and whole milk, which blend together to create a luscious sauce. Tuna provides the protein, and it's essential to drain it well to avoid excess liquid. Cheddar cheese and parmesan cheese give that classic cheesy pull and a bit of sharpness, while breadcrumbs add crunch. Finally, season with salt and pepper to bring all the flavors together.
This tuna casserole pairs wonderfully with a crisp green salad drizzled with a simple vinaigrette. You might also like to serve it alongside some crusty bread to soak up any extra creamy sauce, making it a complete meal.
Start by preheating your oven to 350°F (175°C). This ensures it'll be ready to bake the casserole once everything is assembled. As the oven heats, cook the egg noodles according to the package instructions. You want them al dente, as they'll continue to cook a bit in the oven. Once done, drain and set them aside.
Next, grab a large skillet and melt the butter over medium heat. Add the chopped onion, minced garlic, and diced celery. Sauté them for about 5 minutes until they're nice and soft. This step boosts the flavor, making the dish truly savory.
Stir in the frozen peas, cream of mushroom soup, and whole milk. Mix everything until well combined. The peas will thaw quickly in the hot mixture. Now, gently fold in the drained tuna and cooked noodles, ensuring everything is well mixed.
Transfer this mixture to a greased 9x13-inch baking dish. In a small bowl, combine the cheddar cheese, breadcrumbs, and parmesan cheese. Sprinkle this mixture evenly over the casserole. It will melt and form an irresistible golden crust.
Place the dish in the preheated oven and bake for 25-30 minutes. You're looking for a top that's golden brown and bubbly. Once done, let it cool slightly before serving. This resting time helps the casserole set, making it easier to serve.
