Ingredients
- 12 oz wide egg noodles
- 2 cans (5 oz each) tuna in water, drained
- 1 cup frozen peas
- 1 medium onion, finely chopped
- 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
- 1/4 cup grated Parmesan cheese
- 1 teaspoon dried thyme
- Salt and black 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 chopped 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 minute to create a roux. Gradually pour in milk and broth while whisking constantly to prevent lumps.
Step 4: Bring the sauce to a simmer and cook until thickened, about 3-4 minutes. Stir in shredded cheddar cheese until melted and smooth. Season with dried thyme, salt, and pepper.
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. In a small bowl, mix breadcrumbs with Parmesan cheese and sprinkle evenly over the top.
Step 7: Bake for 25-30 minutes until the casserole is bubbly and the topping is golden brown. Let it rest for 5 minutes before serving.
Expert Tips for Perfect Tuna Casserole
Choose Quality Tuna: Opt for solid white tuna packed in water for the best texture and flavor. The quality of your tuna makes a significant difference in the final dish.
Don’t Overcook Noodles: Cook the egg noodles just until al dente since they’ll continue cooking in the oven. This prevents them from becoming mushy.
Customize Your Topping: For extra crunch, mix crushed potato chips or fried onions with the breadcrumbs. You can also add a sprinkle of paprika for color.
Make Ahead Friendly: Assemble the casserole up to a day in advance, cover, and refrigerate. Add 10-15 minutes to the baking time when cooking from cold.
