How to Make Low Carb Philly Cheesesteak Casserole
Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This ensures that your casserole cooks evenly and becomes perfectly bubbly as it bakes.
Step 2: Sauté the Vegetables
In a large skillet over medium heat, add olive oil. Once hot, toss in the diced onions and bell peppers. Sauté them for about 5-6 minutes until they soften. Adding minced garlic at this point gives off an amazing aroma and enhances the flavor base.
Step 3: Brown the Beef
Now it’s time to add the ground beef! Stir it into the skillet with the vegetables. Season with salt and pepper as you cook it down. Break up the meat with a spatula until it’s fully browned—this should take around 7-8 minutes. Browning adds depth and richness to your dish.
Step 4: Mix in Flavor
Once your beef is browned, pour in Worcestershire sauce. This will elevate all those wonderful flavors in your casserole—don’t skip this step!
Step 5: Add Cream Cheese
Lower the heat and stir in softened cream cheese until melted and combined with the meat mixture. This creates that creamy texture we all love in casseroles!
Step 6: Assemble Your Casserole
Transfer this mouthwatering mixture into your prepared baking dish and spread it out evenly.
Step 7: Layer on the Cheese
Next, layer sliced provolone cheese over your beef mixture, followed by sprinkling shredded mozzarella on top. Trust me; this cheesy goodness is what makes this dish so irresistible!
Step 8: Bake Until Bubbly
Pop your baking dish into the oven for about 20-25 minutes until everything is melted, bubbly, and slightly golden on top. The wait will be worth it!
Step 9: Let It Rest
Once baked, allow your casserole to rest for about 5 minutes before serving. This helps everything meld together beautifully so each slice is perfect.
Enjoy your delicious Low Carb Philly Cheesesteak Casserole! Whether it’s a busy weeknight dinner or a gathering with friends, this dish is sure to impress everyone at the table!
