How to Make Philly Cheesesteak Grilled Cheese Casserole
Follow these simple steps to prepare this delicious dish:
Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). While it’s heating up, grab a trusty baking dish and spray it generously with nonstick cooking spray.
Step 2: Sauté Your Veggies
In a large skillet over medium heat, melt two tablespoons of butter. Toss in your sliced onions, mushrooms, and green bell peppers. Sauté until they’re soft and aromatic—about five minutes should do the trick.
Step 3: Add the Beef
Once your veggies are nice and tender, add in your thinly sliced beef. Cook until it’s no longer pink—this usually takes about three to four minutes. Don’t forget to sprinkle some salt, pepper, and Worcestershire sauce while it cooks for extra flavor.
Step 4: Layer It Up
Now comes the fun part! Start layering half of your bread slices at the bottom of your prepared baking dish. Spread half of your meat mixture over these slices followed by half of your shredded cheese. Repeat this process with the remaining bread slices, meat mixture, and top it off with more cheese.
Step 5: Make It Saucy
Melt another couple tablespoons of butter in a small bowl along with some garlic powder (and more Worcestershire sauce if you’re feeling adventurous). Drizzle this glorious concoction over your layered casserole.
Step 6: Bake Until Golden
Place your casserole in the oven and bake for about thirty minutes or until it’s golden brown and bubbly on top. Your kitchen will smell so good; you might just lose track of time!
Transfer to plates and drizzle any remaining sauce over each serving for the perfect finishing touch.
And there you have it—a delectable Philly Cheesesteak Grilled Cheese Casserole that’s not just filling but also brimming with flavors that’ll make everyone come back for seconds! Serve it at parties or as an indulgent family dinner; either way, get ready for compliments galore!
