Keto Philly Cheesesteak Casserole

Ingredients:

• 1 lb (450g) beef steak (like ribeye or sirloin), thinly sliced
• 2 tbsp olive oil or avocado oil
• 1 medium onion, thinly sliced
• 1 green bell pepper, thinly sliced
• 1 red bell pepper, thinly sliced
• 4 oz (115g) mushrooms, sliced
• 4 cloves garlic, minced
• 1 cup heavy cream
• 1 cup shredded provolone cheese
• 1 cup shredded mozzarella cheese
• 1 tsp dried oregano
• 1 tsp dried basil
• Salt and pepper to taste
• Fresh parsley for garnish (optional)

Instructions:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Cook the Beef: In a large skillet over medium-high heat, add 1 tablespoon of oil. Add the sliced beef and cook until browned. Remove the beef from the skillet and set aside.
3. Sauté Vegetables: In the same skillet, add the remaining 1 tablespoon of oil. Add the sliced onion, bell peppers, and mushrooms. Cook until the vegetables are tender, about 5-7 minutes. Add the minced garlic and cook for an additional 1-2 minutes.
4. Combine Ingredients: Return the beef to the skillet with the vegetables. Stir in the dried oregano and basil, and season with salt and pepper. Mix well.
5. Add Cream: Reduce the heat to low and pour in the heavy cream. Stir until everything is well combined and heated through.
6. Transfer to Baking Dish: Transfer the beef and vegetable mixture to a baking dish.
7. Add Cheese: Sprinkle the shredded provolone and mozzarella cheese evenly over the top.
8. Bake: Place the baking dish in the preheated oven and bake for 15-20 minutes, or until the cheese is melted and bubbly.
9. Garnish and Serve: Garnish with fresh parsley if desired. Let the casserole cool for a few minutes before serving.
