How to Make Keto Philly Cheesesteak Casserole
-
Preheat Oven: Start by preheating your oven to 350°F and greasing a 9×13 baking dish. This ensures your casserole won’t stick and will bake evenly.
-
Chop Vegetables: Gather your veggies and chop them up. Dice the onion, mince the garlic, slice the mushrooms, and cut the bell peppers into bite-sized pieces for hearty bites.
-
Brown Beef: In a skillet over medium heat, add the ground beef. Cook until well browned, which should take about 5-7 minutes. Drain any excess fat and set the beef aside.
-
Sauté Veggies: In the same skillet, pour in some olive oil, then add the bell peppers, onion, and garlic. Sauté for several minutes until the onion is translucent and the peppers soften.
-
Add Mushrooms: Toss in the sliced mushrooms and continue cooking for an additional 5-7 minutes, until they become tender and release their juices.
-
Combine Mixtures: Return the browned beef to the skillet with the sautéed veggies. Season with salt and pepper, stirring to combine for a delicious meld of flavors.
-
Prepare Cheese Sauce: In a separate saucepan, melt the cream cheese and heavy cream over medium heat. Stir in half of the mozzarella cheese until smooth and creamy.
-
Mix it Up: Pour the cheese mixture into the beef and vegetable combination, stirring well to ensure everything is coated in that creamy goodness.
-
Transfer to Baking Dish: Spoon the mixture into the greased baking dish, spreading it out evenly. Top it off with the remaining mozzarella and sprinkle with parmesan cheese for added flavor.
-
Bake Casserole: Place the baking dish in the oven and bake for 15-20 minutes. You’ll know it’s ready when the cheese is melted and bubbly! For an extra touch, broil it for a few minutes for a crispy top.
-
Let it Rest: Allow the casserole to sit for 5 minutes before serving. This resting time helps set the layers and makes serving easier!
Optional: Garnish each serving with fresh chopped herbs for an added pop of color and flavor.

Keto Philly Cheesesteak Casserole Recipe FAQs
How do I choose ripe bell peppers for my casserole?
Absolutely! Look for bell peppers that are firm and heavy for their size. The skin should be shiny and free of blemishes. Dark spots can indicate overripeness. Green peppers are less sweet and slightly bitter, while red, yellow, and orange peppers are sweeter; choose based on your flavor preference!

Store any leftovers in an airtight container in the fridge for up to 5 days. Make sure they are cooled completely before sealing to maintain texture. When ready to enjoy, just reheat in the microwave or oven until warmed through. This casserole keeps its creamy goodness beautifully!
Can I freeze my Keto Philly Cheesesteak Casserole?
Yes! For long-term storage, freeze the casserole in an oven-safe container for up to 3 months. To freeze, allow it to cool completely, then wrap it tightly with plastic wrap and aluminum foil to prevent freezer burn. Before reheating, thaw it overnight in the refrigerator, and adjust the cooking time accordingly when warming up.
What should I do if my casserole is too runny?
If your Keto Philly Cheesesteak Casserole ends up too runny, it might be because the cream cheese mixture wasn’t thickened enough. To thicken it, you can return it to the heat and let it simmer for a few minutes until the sauce reduces. Alternatively, you can add a tablespoon of almond flour to absorb some of that excess moisture, mixing it in thoroughly.
Are there any dietary considerations for this recipe?
Yes, this dish is gluten-free and low-carb, great for those following a keto diet! However, be mindful of potential allergies. Always use gluten-free cheese and double-check labels if you’re serving guests with dairy allergies. You can also substitute with plant-based cheeses for a dairy-free version.
How do I make this dish more flavorful without adding carbs?
Very good question! You can enhance the flavor by incorporating spices such as paprika, smoked paprika, or Italian seasoning. Fresh herbs like basil or parsley mixed in before serving will add a pop of flavor without the added carbs. You could also consider adding a hint of Worcestershire sauce for an even deeper flavor profile!
