Step‑by‑Step Instructions for Low Carb Philly Cheesesteak Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven is warming up, take a 9×13 baking dish and spray it generously with non-stick cooking spray to prevent sticking. This will ensure that your Low Carb Philly Cheesesteak Casserole comes out smoothly after baking, making serving a breeze.
Step 2: Sauté the Vegetables
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Once shimmering, add the diced onions and bell peppers, sautéing for about 5-6 minutes. Watch for them to soften and become fragrant, creating a delicious base for your casserole, and stirring occasionally to ensure even cooking.
Step 3: Add Garlic
Next, stir in the minced garlic and continue to cook for an additional 30 seconds, stirring constantly to prevent the garlic from burning. You’ll notice a wonderful aroma filling your kitchen—this step adds an essential depth of flavor to your Low Carb Philly Cheesesteak Casserole.
Step 4: Cook the Ground Beef
Add 2 pounds of ground beef to the skillet with the sautéed vegetables, breaking it apart with a spatula. Season generously with salt and pepper, cooking for about 7-8 minutes, or until the beef is fully browned. Look for no pink bits; drain any excess fat if necessary to keep the casserole from becoming greasy.
Step 5: Combine with Cream Cheese
Once the beef is brown, mix in 2 tablespoons of Worcestershire sauce for an umami kick. Reduce the heat and add 8 ounces of softened cream cheese, stirring until melted and fully incorporated. This will create a rich, creamy mixture that will bind the flavors of your Low Carb Philly Cheesesteak Casserole beautifully.
Step 6: Transfer to Baking Dish
Carefully transfer the meat and vegetable mixture into your prepared baking dish, spreading it out evenly with a spatula. This ensures every bite of your Low Carb Philly Cheesesteak Casserole has that delicious filling. Layer 8 ounces of torn provolone cheese evenly over the meat, then add 1.5 cups of shredded mozzarella cheese on top for that perfect melty finish.
Step 7: Bake to Perfection
Place the baking dish in your preheated oven and bake for 22-25 minutes. Keep an eye on the casserole; it’s ready when the cheese is melted, bubbly, and slightly golden. The delightful smell wafting through your kitchen will have everyone eagerly anticipating dinner.
Step 8: Rest Before Serving
Once baked, remove the dish from the oven and allow it to rest for about 5 minutes. This resting time helps the casserole set and makes it easier to serve. You’ll be left with a bubbling, golden Low Carb Philly Cheesesteak Casserole that’s sure to impress everyone at your table!

Low Carb Philly Cheesesteak Casserole Recipe FAQs
How do I choose ripe vegetables for this casserole?
Absolutely! For the bell peppers, choose ones that are firm and glossy—avoid any that have dark spots or wrinkling. The onions should be dry and have a smooth skin.

What’s the best way to store leftovers?
Very! Store your Low Carb Philly Cheesesteak Casserole in an airtight container in the refrigerator for up to 4 days.

What should I do if the casserole is too watery?
If you find your casserole is too watery post-baking, there are a couple of things you can do! Start by making sure you properly drain any grease from the cooked beef and sweat the vegetables out well to remove excess moisture. For a quick fix, you can thicken the dish with a little cornstarch mixed in water and simmer it gently on the stovetop until it thickens before serving. Next time, ensure to sauté the onion and peppers until they’re nicely softened to eliminate excess water!
Are there any dietary restrictions to consider with this recipe?
Most definitely! If you’re cooking for someone with dairy allergies, the cream cheese and cheeses can be substituted with dairy-free alternatives.
