Slow Cooker Philly Cheesesteak Casserole

Slow Cooker Philly Cheesesteak Casserole gives you all of the flavors of the sandwich, but without a hoagie roll, in a hearty dish made in a slow cooker! With tender ground beef, vibrant bell peppers, and savory onions mixed in a creamy blend of cheddar cheese soup and sour cream, this dish promises to satisfy your cravings for the classic Philly cheesesteak in a whole new way.

Ingredients & Substitutions

Ground Beef: The meaty base of the casserole is ground beef. It is cooked before it is added to the slow cooker. You could also try this dish with ground chicken or ground turkey.

Vegetables: Sticking with the classic flavors of the Philly cheesesteak, I added green bell peppers, red bell peppers, and onions.

Hash Browns: To add some substance to the casserole, look for a bag of frozen hash browns to add to the slow cooker. This is meant to replace the lack of bread (like in the sandwich).

Cheddar Cheese Soup: Cheddar cheese soup forms the creamy, cheesy base of the casserole. It combines with sour cream to create a sauce that coats the other ingredients.

Cheese: We prefer this casserole topped with shredded mozzarella cheese. We tested it with provolone, and if you prefer that flavor (which does stand out), you could use that. Or, try it with Monterey Jack, pepper jack, or your favorite kind of cheese.

Can I Make The Casserole Without A Slow Cooker?

Sure! To make the casserole without a slow cooker, follow these steps:

1. Preheat oven to 350°F.
2. Cook the ground beef in a large skillet as instructed. Add garlic.
3. To the skillet with the beef, add the bell peppers and onions. Cook for 5-7 minutes, or until softened.
4. In a separate bowl, mix the cheddar cheese soup, sour cream, and Worcestershire sauce.
5. In a large mixing bowl, combine the soup mixture, frozen hash browns, and beef and vegetables. Stir until everything is evenly coated.
6. Spread the mixture into a greased 9×13-inch baking dish.
7. Sprinkle the mozzarella cheese on top.
8. Cover with aluminum foil and bake for 30-35 minutes, or until the casserole is bubbly and the cheese is melted and golden brown.
9. If desired, remove the foil and let the casserole cook an additional 5-10 minutes. This will brown the cheese even more.
10. Let the casserole cool for a few minutes before serving.
