Ingredients (Serves 6)
Main Ingredients
1 1/2 pounds thinly sliced beef steak (ribeye or sirloin)
4 cups gold potatoes, diced (skin-on or peeled)
1 red bell pepper, sliced
1 green bell pepper, sliced
1 small red onion, sliced
3 cloves garlic, minced
1 cup shredded mozzarella or provolone cheese
1/2 cup crumbled feta cheese
1 teaspoon dried oregano
1/2 teaspoon smoked paprika (optional)
Salt and pepper to taste
2 tablespoons olive oil
1/4 cup beef broth
Instructions
Prepare the beef and vegetables
Thinly slice the steak into bite-sized strips. Wash and dice the potatoes. Slice peppers and onion.
Layer in the crockpot
Drizzle olive oil on the bottom of the crockpot. Add half the potatoes, beef, peppers, onions, and garlic. Season with oregano, paprika, salt, and pepper. Repeat the layers.
Add broth and cover
Pour the beef broth evenly over the mixture. Cover and cook on low for 7–8 hours or high for 4–5 hours, until potatoes are tender and beef is cooked through.
Add the cheeses
About 15–20 minutes before serving, sprinkle shredded mozzarella/provolone and crumbled feta evenly over the top. Cover again and let the cheese melt.
Serve
Scoop into bowls and garnish with fresh parsley or olives if desired. Serve hot with a side salad or crusty bread.
Tips
Use thinly sliced steak – Ribeye or sirloin sliced thinly against the grain ensures tender, melt-in-your-mouth beef.
No soggy potatoes – Use waxy potatoes like Yukon Golds which hold up better in slow cooking than russets.
Layer smart – Keeping cheese for the end prevents it from overcooking or turning rubbery.
Season generously – The slow cooker dulls some flavors, so don’t be afraid to salt and season each layer lightly.
Pre-sear (optional) – For extra flavor, you can briefly sear the steak and sauté onions/peppers before adding to the crockpot.
Variations
Low-Carb Version: Replace potatoes with cauliflower florets or turnips for a keto-friendly alternative.
Cheese Swap: Use shredded Swiss, provolone, or goat cheese in place of mozzarella/feta for different flavor profiles.
Add Greens: Stir in spinach or kale during the last 30 minutes of cooking for added nutrition.
Spicy Kick: Add crushed red pepper flakes or chopped jalapeños for heat.
Make it a Meal Prep: Portion into containers and refrigerate for up to 4 days. Reheats well for easy lunche.
Q&A
Can I use ground beef instead of sliced steak?
Yes, browned ground beef works well and speeds up prep. Just cook it first before adding to the crockpot.
Can I prep this the night before?
Absolutely. Layer everything (except cheese) in the crockpot insert, cover, and refrigerate overnight. In the morning, place it in the base and cook as directed.
How do I make this dairy-free?
Skip the cheeses or use dairy-free alternatives. The casserole will still be hearty and flavorful from the beef and veggies.
Can I freeze leftovers?
Yes. Let the casserole cool completely, then portion into airtight containers and freeze for up to 2 months. Reheat in the microwave or oven.
What can I serve with this dish?
A light cucumber tomato salad or lemony arugula salad complements the richness perfectly. You could also add warm pita or low-carb flatbread.
