The Good Stuff You’ll Need
For the Filling:
1 lb ground beef (or thinly sliced ribeye if you’re going all out)
1 tbsp olive oil
1 green bell pepper, diced
1 red bell pepper, diced
1 medium yellow onion, sliced
2 cloves garlic, minced
1 tsp Worcestershire sauce
1/2 tsp paprika
Salt + pepper to taste
For the Creamy Layer:
4 oz cream cheese, softened
1/4 cup mayonnaise
1/4 cup sour cream
2 eggs
1/2 tsp garlic powder
1/2 tsp onion powder
Pinch of cayenne (optional but fun)
Topping:
2 cups shredded provolone cheese (or mozzarella if you prefer meltier vibes)
Optional: sliced banana peppers or jalapeños on top
Let’s Do This
Step 1: Cook the Filling
In a large skillet, heat the olive oil over medium heat. Sauté the onion and peppers until softened, about 6–8 minutes. Add the garlic and cook for 1 minute more. Scoot the veggies to the side and add the ground beef. Cook until browned and crumbled, seasoning with salt, pepper, Worcestershire, and paprika. Stir everything together and remove from heat.
Step 2: Make It Creamy
In a mixing bowl, whisk together the cream cheese, mayo, sour cream, eggs, garlic powder, onion powder, and cayenne until smooth and well combined. This is your secret weapon layer—it makes everything rich and luscious.
Step 3: Assemble the Casserole
Preheat your oven to 375°F (190°C). In a greased 9×13-inch baking dish, spread the beef and veggie mixture evenly across the bottom. Pour the creamy mixture over the top and spread it out with a spatula. Sprinkle the shredded cheese all over like it’s your job. Add any optional toppings like banana peppers or jalapeños.
Step 4: Bake Until Bubbling
Pop that beauty in the oven and bake for 25–30 minutes, until the cheese is melted and slightly golden and the edges are bubbling. Let it sit for 5 minutes before slicing.
Step 5: Dig In
Serve warm, straight out of the dish, maybe with a little side salad if you’re feeling balanced. Or toast up some hoagie rolls and spoon this right in for a deconstructed cheesesteak sandwich moment.
Serving Suggestions
Serve with a crunchy side salad or roasted broccoli for contrast.
Stuff it into toasted buns for a next-level sandwich.
Add a drizzle of hot sauce or spicy mayo if you like it with a kick.
Switch It Up
Go low-carb: skip the bun and serve with cauliflower rice.
Add mushrooms: toss in sliced mushrooms with the peppers for extra umami.
Use different cheeses: try a mix of provolone, cheddar, or pepper jack.
Make-Ahead Tips
Assemble the casserole ahead and refrigerate up to 24 hours before baking.
Leftovers reheat beautifully — just cover with foil and warm at 350°F.
Freezes well too! Cool completely, cover tightly, and freeze up to 2 months.
