Ingredients
- Ribeye steak or thinly sliced beef: Brings rich flavor and stays juicy Look for nicely marbled cuts or pre-sliced for convenience
- Large onion: Adds sweetness and depth Choose onions with tight skin and firm feel
- Green and red bell peppers: Provide color and a crisp, fresh bite Pick peppers that are glossy and heavy for size
- Garlic: Gives aroma and punch Use fresh cloves for maximum flavor
- Mushrooms: Brings earthiness and meaty texture Optional but highly recommended for an extra layer
- Shredded provolone cheese or mozzarella: Melts perfectly and adds gooeyness Buy in blocks for the best melt
- Cream cheese: Lends creaminess and subtle tang Let it fully soften for smooth blending
- Mayonnaise: Helps bind the sauce and adds richness Go for real mayo rather than low fat
- Beef broth: Deepens the beefy undertone Low sodium broth gives control over salt
- Worcestershire sauce: Adds savory umami and complexity Use a splash more if you like
- Salt and black pepper: Brightens and seasons every layer Always taste for balance
- Garlic powder and onion powder: Backs up the fresh aromatics Pick quality blends for more flavor
- Cooked pasta (optional): Optional for a filling meal Use any short pasta that holds sauce
- Crushed crackers or breadcrumbs: Supplies irresistible crunch Choose panko for extra crispy or buttery crackers for richness
- Butter: Helps brown the topping and ties it together Melt before mixing so crumbs stay light
Instructions
- Preheat the Oven:
- Set your oven to 350°F or 175°C and grease a 9x13 inch baking dish This ensures nothing sticks and promotes even cooking
- Cook the Steak:
- Lay slices of ribeye into a hot skillet over medium heat Cook just until brown and cooked through Remove them so they stay tender not chewy
- Sauté the Vegetables:
- In the same pan add onions bell peppers mushrooms if using and garlic Let these slowly soften for 5 to 7 minutes Season generously with salt black pepper garlic powder and onion powder They should turn sweet and fragrant
- Prepare the Cheese Mixture:
- Mix softened cream cheese mayonnaise beef broth and Worcestershire sauce in a bowl Stir until silky and completely smooth This makes the luscious sauce that brings everything together
- Assemble the Casserole:
- Layer the cooked steak and sautéed veggies into your prepped baking dish If you are using pasta fold it in now Pour the cheese sauce over top and spread to fill every nook Scatter on a thick blanket of shredded provolone or mozzarella
- Add the Topping:
- Combine crushed crackers or breadcrumbs with melted butter in a small bowl Mix so everything gets a bit glossy Sprinkle this evenly over the cheese layer for the classic casserole crunch
- Bake:
- Slide the casserole onto the center rack in your oven Bake for 25 to 30 minutes Watch for the cheese to bubble up and the topping to turn golden Let it rest a few minutes before slicing this helps it settle and makes serving easier

Storage Tips
This casserole is just as delicious the next day Cover the dish with foil or transfer to airtight containers and refrigerate for up to four days To reheat try using the oven at 325°F for about 10 to 15 minutes so the topping stays crunchy A quick zap in the microwave works too but cover to prevent drying
