Ingredients

• 12 oz egg noodles
• 2 tbsp butter
• 1 medium yellow onion, diced
• 2 cloves garlic, minced
• 8 oz white or cremini mushrooms, sliced
• 3 tbsp all-purpose flour
• 2 cups whole milk
• 1 cup chicken or vegetable broth
• 1 cup grated Parmesan cheese
• 2 5-oz cans canned tuna (in water), drained
• 1 cup frozen peas
• 1 tsp salt
• 0.5 tsp black pepper
• 1.5 cups shredded cheddar cheese
• 0.5 cup panko breadcrumbs
• 1 tbsp olive oil

Directions

Step 1

Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch casserole dish and set aside.

Step 2

Cook the egg noodles according to package instructions until al dente. Drain, rinse with cold water, and set aside.

Step 3

In a large skillet, melt the butter over medium heat. Add the diced onion and cook for about 3 minutes until softened. Stir in the minced garlic and cook for an additional 30 seconds.

Step 4

Add the sliced mushrooms to the skillet and sauté for 5-7 minutes, until the mushrooms are tender and their liquid has evaporated.

Step 5

Sprinkle the flour over the mushroom mixture and stir well to coat. Cook for 1 minute to eliminate the raw flour taste.

Step 6

Gradually whisk in the milk and chicken or vegetable broth, stirring constantly to create a smooth sauce. Bring to a gentle simmer and cook until the sauce has thickened, about 3-5 minutes.

Step 7

Stir in the grated Parmesan cheese and season with salt and black pepper. Remove the skillet from heat.

Step 8

In a large mixing bowl, combine the cooked noodles, creamy sauce, drained tuna, frozen peas, and 1 cup of shredded cheddar cheese. Mix well to evenly distribute the ingredients.

Step 9

Transfer the mixture to the prepared casserole dish, spreading it out evenly. Sprinkle the remaining 0.5 cup of cheddar cheese over the top.

Step 10

In a small bowl, combine the panko breadcrumbs with olive oil. Sprinkle the breadcrumb mixture evenly over the casserole.

Step 11

Bake the casserole for 25-30 minutes, or until the top is golden brown and the edges are bubbling.

Step 12

Allow the casserole to cool slightly for 5 minutes before serving. Enjoy!
