How to Make Philly Cheesesteak Grilled Cheese Casserole
Start with Preparing Ingredients
Begin by thinly slicing the ribeye steak against the grain—this ensures tenderness in every bite. Dice your onion, bell pepper, and mushrooms while preheating your skillet over medium heat.
Sauté Vegetables
Add a drizzle of olive oil to your hot skillet before tossing in those onions. Cook until they turn translucent and aromatic—around five minutes should do! Add green peppers and mushrooms next, stirring until they soften.
Cook Steak
Push those veggies aside in the skillet (they’re not getting off that easy) and add your sliced ribeye. Cook until browned—the sizzling sound will drive you wild! Season with salt, pepper, and minced garlic during the last couple of minutes.
Assemble Casserole
Grab your greased baking dish (don’t forget that butter!), then layer half of your sourdough cubes on the bottom. Next comes half of the cooked steak mixture followed by layers of cheddar and provolone. Repeat these layers until ingredients are used up.
Pour Egg Mixture
In a mixing bowl, whisk together eggs with milk—this binds everything together beautifully! Pour this mixture evenly over all layers in your casserole dish. Press down slightly so every piece gets soaked in eggy goodness.
Bake
Preheat your oven to 350°F (175°C), then cover your casserole with aluminum foil—this traps steam while baking. Bake for about thirty minutes before removing foil; bake an additional ten minutes until golden brown on top.
Cool & Serve
Once baked to perfection, let it cool slightly—this part is crucial unless you enjoy burnt tongues! Slice into squares or rectangles before serving. Enjoy every cheesy bite while reminiscing about that first cheesesteak encounter!
Now you’re ready to entice family or friends into devouring this Philly Cheesesteak Grilled Cheese Casserole like there’s no tomorrow! Happy cooking!
