Ingredients You’ll Need
This casserole uses simple, wholesome ingredients you likely already have in your kitchen.

- Vegetables: Red and green bell peppers, yellow onion, and garlic bring classic Philly cheesesteak flavors to life.
- Seasonings: Salt, black pepper, paprika, and dried Italian seasoning enhance the dish without overpowering it.
- Cheese: Cream cheese adds a creamy texture while provolone melts perfectly on top. Mozzarella or white cheddar can be used as alternatives.
- Cauliflower Rice: The perfect low-carb substitute for bread, keeping the casserole filling and nutritious.
Why Cauliflower Works So Well
Cauliflower rice is more than just a low-carb alternative. It’s loaded with nutrients and adds volume without extra calories. Benefits include:
- High in fiber, which supports digestion
- Rich in vitamins C, K, and B6
- Contains potassium, manganese, and folate
It’s versatile and absorbs the flavors of the casserole, giving you a soft, satisfying base that mimics traditional sandwich bread without the carbs.
How to Make Low-Carb Philly Cheesesteak Casserole
Follow these steps for a quick, flavorful dinner:
- Cook the Beef and Vegetables: Preheat a large oven-safe skillet over medium heat. Add the ground beef, bell peppers, onions, and garlic. Break the beef into small pieces as it cooks, about 8–10 minutes. Drain excess grease if needed.
- Add Seasonings and Cream Cheese: Reduce heat to low. Stir in salt, pepper, paprika, and Italian seasoning. Add cauliflower rice and cream cheese, mixing until the cream cheese melts and combines smoothly with the beef mixture.
- Top with Cheese: Layer slices of provolone cheese evenly over the casserole.
- Bake Until Golden: Bake in a preheated 350°F oven for 10–12 minutes, or until the cheese is melted and lightly golden.
- Garnish and Serve: Remove from oven and let sit for 5 minutes. Garnish with fresh parsley if desired. Serve warm.
This method ensures a creamy, cheesy casserole with tender vegetables and a rich flavor that rivals any traditional Philly cheesesteak.
Tips for the Perfect Casserole
- For extra flavor, add 2–3 tablespoons of Worcestershire sauce or coconut aminos to the beef mixture.
- Garlic powder can enhance the aroma and depth; add ½ to 1 teaspoon to taste.
- If you don’t have an oven-safe skillet, transfer the mixture to a casserole dish before adding cheese and baking.
- Leftovers store well in an airtight container in the fridge for 3–4 days. Reheat in the oven or microwave with a splash of water to maintain moisture.
Serving Suggestions
This casserole is hearty enough to serve on its own but pairs beautifully with:
- A simple side salad with a light vinaigrette
- Steamed or roasted asparagus
- Low-carb cornbread muffins for a comforting touch
It’s a complete, satisfying meal that’s family-friendly and perfect for anyone following a low-carb or keto diet.
