-
Sauté the diced onion and bell peppers in a large skillet with olive oil over medium heat for about 5-6 minutes, or until they become tender and fragrant. Their lovely colors will brighten your dish!
-
Add the minced garlic to the skillet, cooking for an additional 30 seconds. This will infuse the dish with a wonderful aroma that will make your taste buds tingle!
-
Brown the ground beef in the skillet, breaking it apart as it cooks. Season with salt and pepper, cooking for 7-8 minutes until it’s browned and fully cooked through. Don’t forget to drain any excess fat!

Expert Tips for Low Carb Philly Cheesesteak Casserole
-
Quality Meat: Use high-fat ground beef (80/20) to ensure your casserole is juicy and flavorful. Leaner meat may result in a drier texture.
-
Don’t Skimp on Cheese: Use both provolone and mozzarella for the ultimate gooey experience. Reducing the cheese will diminish the classic cheesesteak flavor.
-
Drain Fat: Always drain excess fat after browning the beef. This prevents a greasy casserole and helps achieve the perfect texture.
-
Let it Rest: Allow the casserole to sit for at least 5 minutes after baking. This resting time helps the layers settle, so each scoop is hearty and holds its shape.
-
Veggie Variations: Feel free to add sautéed mushrooms or jalapeños for an extra flavor punch. These can elevate your low carb Philly cheesesteak casserole to new heights!
Storage Tips for Low Carb Philly Cheesesteak Casserole
Fridge: Store leftovers in an airtight container for up to 4 days, keeping the comforting flavors fresh and ready for quick meal options.

Reheating: When ready to enjoy, reheat in the oven at 325°F (165°C) until warmed through, or microwave covered with a damp paper towel to retain moisture and prevent drying out.

You can prep the entire casserole up to 24 hours in advance by assembling it, covering it tightly with plastic wrap, and refrigerating.

Low Carb Philly Cheesesteak Casserole Recipe FAQs
What type of ground beef should I use for the casserole?
Absolutely! For the best flavor and texture, I recommend using ground beef with an 80/20 fat ratio. This provides just enough fat to keep the casserole juicy without being greasy. If you’re looking for a lighter option, lean ground turkey or chicken can work as substitutes, but they may result in a slightly drier final product.
How should I store leftovers?
Great question! Store any leftovers in an airtight container in the refrigerator for up to 4 days. This keeps the casserole fresh and ready for quick meals! If you find yourself with extra portions, you can freeze them. Just make sure to wrap the individual servings tightly in freezer-safe containers or wrap for up to 3 months.
Can I freeze the casserole?
Yes, you can! To freeze your Low Carb Philly Cheesesteak Casserole, first let it cool completely. Then portion it into freezer-safe containers. Make sure to label them with the date. When you’re ready to enjoy it, thaw it overnight in the refrigerator. Simply reheat in the oven at 325°F (165°C) until heated through.
What should I do if my casserole is too oily?
If you find your casserole is a bit greasy, this usually happens if there’s excess fat from the ground beef. The solution is to drain the meat well after browning it before mixing in the other ingredients. This helps prevent that unwanted oily texture and keeps your casserole delectable!
Is this dish safe for those with cheese allergies?
Unfortunately, this dish contains both provolone and mozzarella cheeses, which would not be suitable for anyone with cheese allergies. As a delicious alternative, consider making a cheese-free version by replacing the cheeses with a plant-based cream cheese to maintain a creamy consistency while adhering to dietary restrictions—just be mindful that it will alter the flavor slightly!
