Ingredients & Easy Substitutions
- Ground Beef – The base of the casserole; you can also use sliced steak if you prefer a more authentic cheesesteak texture.
- Bell Peppers – Adds flavor and color. Use a mix of green, red, or yellow.
- Onion – For that classic cheesesteak taste; you can omit if you’re sensitive to carbs.
- Cream Cheese – Adds creaminess to the casserole. Can substitute with heavy cream for a lighter version.
- Shredded Cheese – Use provolone or mozzarella for melty goodness; cheddar also works.
- Garlic – For added depth of flavor.
- Olive Oil – To sauté the vegetables; feel free to use avocado oil or butter instead.
- Salt & Pepper – Simple seasoning to bring out the flavors.
How to Make Keto Philly Cheesesteak Casserole
- Cook the Beef: Preheat oven to 350°F. In a large skillet, cook the ground beef over medium-high heat until browned. Season with salt and pepper, then drain any excess grease. Set the beef aside.
- Sauté the Vegetables: In the same skillet, heat olive oil and sauté the sliced bell peppers, onion, and garlic until softened and fragrant, about 5-7 minutes.
- Combine Ingredients: Add the cooked beef back into the skillet with the vegetables. Stir in the cream cheese until melted and combined.
- Transfer to Baking Dish: Pour the mixture into a greased 9×13-inch baking dish. Top with shredded cheese.
- Bake: Bake in the preheated oven for 15-20 minutes, or until the cheese is melted and bubbly.
- Serve: Let the casserole cool for a few minutes, then dig in and enjoy your cheesy, keto-friendly dinner!
Pro Tips for Perfect Results
- Use Quality Cheese: For the best flavor, grate your own cheese instead of using pre-shredded cheese, which can contain anti-caking agents that affect melting.
- Adjust Ingredients: Feel free to add mushrooms or swap beef for chicken for a variation.
- Keep It Creamy: If you like extra creaminess, add a splash of heavy cream to the mixture before baking.
Storing & Serving Suggestions
- Storage: Store any leftovers in an airtight container in the refrigerator for up to 3 days.
- Reheating: Reheat in the oven at 300°F until warm, or microwave in 30-second intervals.
- Serving Ideas: Enjoy it with a simple side salad or a keto-friendly bread alternative to soak up all the delicious flavors.
