Ingredients

1 lb ground beef

8 oz mushrooms, sliced

1 small onion, diced

1 cup shredded cheddar cheese

2 cloves garlic, minced

1 cup shredded mozzarella cheese

1 can (10.5 oz) cream of mushroom soup

1/2 cup sour cream

Salt and pepper to taste

2 tablespoons olive oil

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

Preheat the oven to 350°F (175°C).

In a large skillet, heat the olive oil over medium heat. Add the onions and garlic and sauté for about 3 minutes until softened.

Add the ground beef, breaking it up with a spoon, and cook until browned. Drain any excess fat.

Stir in the sliced mushrooms and cook for about 5 minutes, until tender. Add the Worcestershire sauce, dried thyme, salt, and pepper. Stir to combine.

In a separate bowl, mix the cream of mushroom soup, sour cream, and milk until smooth.

In a large mixing bowl, combine the cooked pasta, the beef and mushroom mixture, and the soup mixture. Stir everything together until well combined.

Transfer the mixture to a greased 9×13-inch baking dish. Sprinkle the shredded cheddar and mozzarella cheeses evenly on top.

Bake for 25-30 minutes, or until bubbly and the cheese is melted and golden brown.

Let the casserole rest for 5 minutes before serving.

Variations

Gluten-Free: If you prefer a gluten-free option, simply swap out the pasta for a gluten-free variety, and be sure to use a gluten-free cream of mushroom soup.

Add Veggies: I like to throw in some spinach or bell peppers for an extra burst of color and nutrition.

Meat Alternatives: If you’re looking to make this dish lighter, ground turkey or chicken can be substituted for the beef.

Cheese Options: Feel free to mix and match different cheeses—Swiss or Gouda would also work well in this casserole.

Storage/Reheating

Storage: Leftovers can be stored in an airtight container in the fridge for up to 3 days.

Reheating: To reheat, I recommend warming the casserole in the oven at 350°F (175°C) for 15-20 minutes, until heated through. You can also microwave individual servings for 1-2 minutes, but the oven method will keep the cheese from getting too rubbery.

FAQs

How can I make this Mushroom Cheeseburger Casserole spicier?

If you want to add some heat, try mixing in a bit of hot sauce or diced jalapeños into the beef mixture. You could also sprinkle some crushed red pepper flakes on top before baking.

Can I use fresh mushrooms instead of canned?

Absolutely! I prefer fresh mushrooms, and I find they add a great texture and flavor to the casserole. Just be sure to slice them up before adding them to the skillet.

Yes! This casserole can be assembled ahead of time and stored in the fridge for up to 24 hours. When ready to bake, just pop it in the oven and cook as directed.

To make this casserole dairy-free, use dairy-free cheese alternatives and a dairy-free cream of mushroom soup. You could also swap the sour cream for a dairy-free yogurt or cream substitute.
