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-inch baking dish and generously coat it with non-stick cooking spray to prevent any sticking. This will ensure your Philly Cheesesteak Casserole slides out seamlessly once baked.

Step 2: Sauté the Vegetables
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the diced onion and bell peppers, cooking for about 5-6 minutes until they soften and start to become translucent. Stir in the minced garlic and sauté for an additional 30 seconds, allowing the aroma to fill your kitchen before removing the mixture from heat.

Step 3: Brown the Ground Beef
Using the same skillet, add the ground beef and cook over medium heat for 7-8 minutes, breaking it apart with a spatula. Keep stirring until it’s browned and no longer pink. Once the beef is cooked through, mix in the Worcestershire sauce, seasoning with salt and pepper to taste. This mixture will be the heart of your Philly Cheesesteak Casserole.

Step 4: Combine with Cream Cheese
Reduce the heat to low and add softened cream cheese to the skillet with the beef mixture. Stir until the cream cheese melts and blends smoothly, creating a rich and creamy texture. Ensure there are no lumps for an even flavor throughout your casserole. This step enhances the comforting essence of the Philly Cheesesteak Casserole.

Step 5: Assemble the Casserole
Spread the beef and cream cheese mixture evenly into your prepared baking dish. Layer with slices of provolone cheese across the top, allowing it to melt beautifully during baking. Then, sprinkle a generous amount of shredded mozzarella over everything, creating a deliciously gooey topping that will entice everyone at the table.

Step 6: Bake to Perfection
Place the assembled Philly Cheesesteak Casserole in the preheated oven and bake for 20-25 minutes. Keep an eye on it until the cheese is bubbly and golden brown, signaling that it’s ready. The tantalizing smell wafting through your home will have everyone eager for dinner.

Step 7: Cool and Serve
Once your casserole is beautifully golden, remove it from the oven and let it cool for about 5 minutes. This brief resting period allows the flavors to settle and makes serving easier. Prepare to delight your loved ones with this low-carb twist on a classic, as you dish out portions of your savory Philly Cheesesteak Casserole.

Make Ahead Options

This way, you can enjoy delicious, homemade comfort food without the last-minute rush, making dinner truly effortless!

Philly Cheesesteak Casserole Recipe FAQs

What is the best way to choose the right ingredients?
Absolutely! When selecting your bell peppers, look for ones that are firm and shiny, avoiding any that have dark spots or wrinkles.

You can store leftovers in an airtight container in the refrigerator for up to 4 days. Reheating in the microwave or oven will bring back that delicious cheesy goodness, ensuring each bite is as delightful as the first!
