Ingredients

• 12 oz egg noodles
• 4 tbsp unsalted butter
• 1 medium yellow onion
• 2 cloves garlic cloves
• 8 oz mushrooms
• 3 tbsp all-purpose flour
• 2 cups chicken or turkey broth
• 1 cup whole milk
• 1 cup sour cream
• 3 cups leftover cooked turkey
• 1 cup frozen peas
• 2 cups shredded cheddar cheese
• 1 cup panko breadcrumbs
• 1 tbsp olive oil
• 1 tsp salt
• 1 tsp black pepper
• 1 tsp dried thyme

Directions

Step 1

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

Step 2

Cook the egg noodles according to the package instructions until al dente. Drain and set aside.

Step 3

In a large skillet, melt 2 tablespoons of butter over medium heat. Add the diced onion and cook for 3-4 minutes until softened. Add the minced garlic and sliced mushrooms, and cook for an additional 5-6 minutes until the mushrooms are tender and their liquid has evaporated.

Step 4

Stir in the flour, cooking for 1-2 minutes until it forms a paste. Gradually whisk in the chicken or turkey broth and milk, stirring constantly to avoid lumps. Bring the mixture to a simmer and cook for 3-4 minutes until thickened.

Step 5

Remove the skillet from heat and stir in the sour cream, salt, pepper, and dried thyme. Add the cooked turkey, frozen peas, and 1 cup of shredded cheddar cheese. Mix until everything is combined.

Step 6

In a large mixing bowl, combine the cooked egg noodles with the turkey and mushroom mixture. Toss gently to coat, then transfer the mixture to the prepared baking dish.

Step 7

In a small bowl, mix the panko breadcrumbs with 1 tablespoon of olive oil and 2 tablespoons of melted butter. Sprinkle the breadcrumb mixture evenly over the casserole. Top with the remaining 1 cup of shredded cheddar cheese.

Step 8

Bake in the preheated oven for 25-30 minutes, or until the casserole is bubbly and golden on top.

Step 9

Remove from the oven and let cool for 5 minutes before serving. Enjoy your hearty and delicious Leftover Turkey Mushroom Noodle Casserole!
