Ingredients

• 2 tablespoons olive oil
• 1.5 pounds chuck beef, cubed
• 1 teaspoon salt
• 0.5 teaspoon ground black pepper
• 1 large yellow onion, finely chopped
• 3 cloves garlic cloves, minced
• 10 ounces button mushrooms, sliced
• 3 tablespoons all-purpose flour
• 2 cups beef broth
• 1 cup heavy cream
• 1 teaspoon dried thyme
• 0.5 teaspoon dried rosemary, crushed
• 8 ounces uncooked egg noodles
• 1 cup cheddar cheese, shredded
• 2 tablespoons parsley, chopped (optional, for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Season the beef cubes with salt and pepper, then sear them in the skillet until browned on all sides. Remove the beef and set aside.

Step 3

In the same skillet, add the remaining tablespoon of olive oil. Sauté the chopped onion until translucent, about 3-4 minutes. Add the minced garlic and cook for another minute.

Step 4

Stir in the sliced mushrooms and cook until they've released their juices and are slightly golden, about 5-7 minutes.

Step 5

Sprinkle the flour over the mushrooms and stir well, cooking for 1-2 minutes to remove the raw flour taste.

Step 6

Slowly pour in the beef broth while stirring to create a smooth sauce. Add the heavy cream, thyme, and rosemary, and stir until the mixture thickens slightly, about 3-5 minutes.

Step 7

Return the seared beef to the skillet and stir to coat in the sauce. Reduce the heat to low and let it simmer while you prepare the noodles.

Step 8

Cook the egg noodles according to package instructions, but slightly undercook them by 1-2 minutes as they will finish cooking in the oven. Drain the noodles.

Step 9

Mix the partially cooked noodles into the beef and mushroom mixture, ensuring everything is evenly combined.

Step 10

Transfer the mixture to a greased 9x13-inch baking dish. Sprinkle the shredded cheddar cheese evenly over the top.

Step 11

Bake the casserole in the preheated oven for 25 minutes, or until the cheese is melted and bubbly.

Step 12

Remove the casserole from the oven and let it cool slightly for 5 minutes. Garnish with chopped parsley, if desired, and serve warm.
