Ingredients
- 8 ounces egg noodles
- 2 cans (5 ounces each) tuna in water, drained
- 1 cup frozen peas
- 1 small onion, diced
- 2 cloves garlic, minced
- 3 tablespoons butter
- 3 tablespoons all-purpose flour
- 2 cups milk
- 1 cup chicken or vegetable broth
- 1 cup shredded cheddar cheese
- 1/2 cup breadcrumbs
- 1 teaspoon dried parsley
- 1/2 teaspoon paprika
- Salt and pepper to taste
Step-by-Step Instructions
Step 1: Preheat your oven to 375°F (190°C). Cook the egg noodles according to package directions until al dente, then drain and set aside.
Step 2: In a large skillet, melt butter over medium heat. Add diced onion and cook until softened, about 5 minutes. Add minced garlic and cook for another minute until fragrant.
Step 3: Sprinkle flour over the onion mixture and whisk continuously for 1-2 minutes to create a roux. Gradually pour in milk and broth while whisking to prevent lumps.
Step 4: Bring the sauce to a simmer and cook until thickened, about 3-5 minutes. Stir in shredded cheese until melted and smooth. Season with salt, pepper, and parsley.
Step 5: Combine the cooked noodles, tuna, frozen peas, and cheese sauce in a large bowl. Mix gently until everything is evenly coated.
Step 6: Transfer the mixture to a greased 9×13 inch baking dish. Top with breadcrumbs and sprinkle with paprika for color.
Step 7: Bake for 25-30 minutes until bubbly and golden brown on top. Let it rest for 5 minutes before serving.
Expert Tips
Perfect Noodle Texture: Cook noodles just until al dente since they’ll continue cooking in the oven. Overcooked noodles can become mushy in the casserole.
Creamy Sauce Secret: Make sure your roux is cooked for at least a minute before adding liquids – this eliminates the raw flour taste and ensures a smooth sauce.
Customization Ideas: Add sliced mushrooms, diced celery, or corn for extra vegetables. For a different flavor profile, try using different cheeses like Monterey Jack or Swiss.
