Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

• Ground beef
• Mushrooms, sliced
• Onion, diced
• Garlic, minced
• Swiss cheese, shredded or sliced
• Cream cheese
• Sour cream
• Beef broth
• Worcestershire sauce
• Olive oil or butter
• Pasta, egg noodles, or potatoes
• Salt
• Black pepper
• Garlic powder
• Fresh parsley

Directions

I start by cooking the pasta or potatoes until just tender, then I set them aside.

In a large skillet, I heat olive oil or butter and cook the onions and mushrooms until soft and golden. I add the garlic and cook for another minute until fragrant.

I add the ground beef and cook it until browned, breaking it apart as it cooks. Then I stir in Worcestershire sauce, salt, pepper, and garlic powder.

I mix in the cream cheese, sour cream, and beef broth until the sauce becomes creamy and smooth.

I combine the cooked pasta or potatoes with the beef mixture and transfer everything to a greased casserole dish. Then I top it with plenty of Swiss cheese.

I bake the casserole until hot and bubbly with melted golden cheese on top. Before serving, I sprinkle fresh parsley over everything for extra flavor and color.

Variations

For a lower-carb version, I replace the pasta with cauliflower or extra mushrooms. I can also swap Swiss cheese for mozzarella or provolone if I want a milder flavor.

storage/reheating

I reheat portions in the microwave or oven until warmed through. If the casserole becomes a little thick after refrigeration, I add a splash of broth before reheating to keep it creamy.

I can also freeze the casserole for up to 2 months. I thaw it overnight in the refrigerator before reheating.
