Ingredients
  

Ingredients
  • 8 oz egg noodles
  • 2 tablespoons butter
  • 1 medium onion, diced
  • 2 cloves garlic, minced
  • 8 oz mushrooms, sliced
  • 1/4 cup all-purpose flour
  • 2 cups milk
  • 1 cup chicken or vegetable broth
  • 2 cans (5 oz each) tuna in water, drained
  • 1 cup frozen peas, thawed
  • 1 cup shredded cheddar cheese
  • 1/2 cup breadcrumbs
  • 1 teaspoon paprika
  • Salt and pepper to taste
  • Fresh parsley for garnish

Method
 

Instructions
  1. Preheat your oven to 375°F (190°C). Cook the egg noodles according to package directions until al dente. Drain and set aside.
  2. In a large skillet, melt butter over medium heat. Add diced onion and sauté until translucent, about 3-4 minutes. Add garlic and mushrooms, cooking until mushrooms are tender.
  3. Sprinkle flour over the vegetable mixture and cook for 1 minute, stirring constantly. Gradually whisk in milk and broth until smooth. Bring to a simmer and cook until thickened, about 3-5 minutes.
  4. Remove from heat and stir in the drained tuna, peas, and half of the shredded cheese. Season with salt and pepper to taste.
  5. Combine the sauce with the cooked noodles and transfer to a greased 9x13-inch baking dish.
  6. Mix the remaining cheese with breadcrumbs and paprika. Sprinkle evenly over the casserole.
  7. Bake for 20-25 minutes until bubbly and golden brown on top. Let rest for 5 minutes before serving.

Notes

Choose quality solid white albacore tuna packed in water for best flavor. Don't overcook noodles - cook just until al dente since they continue cooking in the oven. For extra crunch, mix crushed potato chips or crispy fried onions with the breadcrumb topping. Assemble casserole up to a day in advance and refrigerate, adding extra baking time if starting from cold.
