Step‑by‑Step Instructions for Philly Cheesesteak Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it warms up, grab a 9×13 baking dish and lightly spray it with non-stick cooking spray to ensure your Philly Cheesesteak Casserole doesn’t stick during baking. This sets a great foundation for your dish, allowing for easy serving later on.

Step 2: Sauté Vegetables
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Once the oil shimmers, add in 1 diced onion and 1-2 chopped bell peppers. Sauté the mixture for about 5-6 minutes, stirring occasionally until the vegetables soften and become fragrant. Add 2 cloves of minced garlic for the last 30 seconds to enhance those savory flavors before removing from heat.

Step 3: Brown the Beef
Next, increase the heat slightly and add in 1 pound of ground beef to the skillet. Season with salt and pepper, then cook for about 7-8 minutes, breaking the meat apart with a spatula until it’s nicely browned and no longer pink. The aroma will fill your kitchen, making everyone eager for that Philly Cheesesteak Casserole!

Step 4: Add Flavorings
Once the beef is browned, stir in 2 tablespoons of Worcestershire sauce, mixing well to ensure the meat is coated evenly. This adds a delightful umami richness that complements the other ingredients perfectly. Continue to cook for an additional minute to let those flavors meld.

Step 5: Incorporate Cream Cheese
Reduce the skillet’s heat to low and add in 8 ounces of softened cream cheese. Stir gently until the cream cheese melts completely and blends into the meat mixture, resulting in a creamy, cohesive blend. You’ll know it’s ready when the mixture looks smooth and velvety, perfect for your casserole.

Step 6: Transfer Mixture
Carefully spread the beef and veggie mixture evenly into your prepared baking dish. Make sure it’s distributed evenly for consistent cooking. This base will hold all the delicious flavors of your Low Carb Philly Cheesesteak Casserole, making it the star of the meal.

Step 7: Add Cheese Toppings
Now for the cheesy goodness! Layer 8 ounces of sliced provolone cheese and a generous 1 cup of shredded mozzarella cheese evenly over the top of the beef mixture. This important step not only adds flavor but also creates a beautifully gooey topping that everyone will love.

Step 8: Bake
Place the baking dish in your preheated oven and bake for 20-25 minutes. Keep an eye on it, and look for the cheese to melt, bubble, and turn a lovely golden color. This visual cue means your Philly Cheesesteak Casserole is almost ready to delight your family!

Step 9: Rest
Once baked, remove the dish from the oven and let it cool for approximately 5 minutes. This resting period allows the casserole to set, making it easier to scoop out servings. The anticipation will be worth it as you get ready to dig into this hearty and satisfying dish!

Philly Cheesesteak Casserole Variations

  • Spicy Kick: Add diced jalapeños or a sprinkle of crushed red pepper flakes for that extra heat that will wake up your taste buds. A little spice can elevate the entire dish!

  • Mushroom Swap: For a vegetarian twist, replace the ground beef with sautéed mushrooms. They’ll absorb all the fantastic flavors, making this a hearty and satisfying option.

  • Cheese Variety: Experiment with different cheeses like Gouda or cheddar to create unique flavor combinations. A blend of cheeses is always a fun way to surprise your palate!

  • Extra Veggies: Include zucchini or spinach to boost the nutritional value and add vibrant color. More veggies mean more flavor and a healthier dish overall.

  • Low Carb Noodles: For an even heartier base, add a layer of spiralized zucchini or shirataki noodles before the meat mixture for a delightful texture without the carbs.

Low Carb Philly Cheesesteak Casserole Recipe FAQs

How do I select the best ground beef for this casserole?
