Ingredients

• 1 lb (450 g) thinly sliced beef steak (such as sirloin or ribeye)
• 4 cups (400 g) cauliflower rice (fresh or frozen)
• 1 medium green bell pepper, diced
• 1 medium red bell pepper, diced
• 1 medium yellow onion, thinly sliced
• 2 cloves garlic, minced
• 1 cup (120 g) shredded provolone cheese
• 1 cup (120 g) shredded mozzarella cheese
• 2 oz (60 g) cream cheese, softened
• 2 tbsp olive oil
• 1 tsp salt
• ½ tsp black pepper
• ½ tsp smoked paprika
• ½ tsp dried oregano

Instructions

Preheat and prep

Preheat oven to 375°F (190°C).

Cook the beef

Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add the thinly sliced beef and cook until browned, about 3–4 minutes. Remove from skillet and set aside.

Sauté the vegetables

In the same skillet, add the remaining tablespoon of olive oil. Sauté the onions and bell peppers until softened, about 5–6 minutes. Add the minced garlic and cook for 1 more minute.

Add cauliflower rice

Stir in the cauliflower rice and cook until just tender, about 4 minutes. Season with salt, pepper, smoked paprika, and oregano.

Mix in cream cheese

Reduce heat to low. Add the cream cheese and stir until melted and well combined with the vegetables.

Combine everything

Return the beef to the skillet and mix everything together.

Assemble the casserole

Transfer the mixture to a greased 9x13-inch (23x33 cm) baking dish.

Add cheese topping

Sprinkle the provolone and mozzarella cheeses evenly over the top.

Bake

Bake for 15–18 minutes, or until the cheese is melted and bubbly.

Rest and serve

Let rest for 5 minutes before serving.

Zusatztipps für die Zubereitung

For the most authentic Philly cheesesteak flavor, slice your beef as thinly as possible. Placing the meat in the freezer for about 20 minutes before slicing can make this easier. When cooking the cauliflower rice, be careful not to overcook it - you want it to maintain some texture in the final dish. The cream cheese adds richness and helps bind everything together, so make sure it's fully incorporated for the best consistency.

Varianten und Anpassungen

This recipe is easily adaptable to suit different tastes while keeping it keto-friendly. Try using Monterey Jack or cheddar cheese instead of provolone for a different flavor profile. For mushroom lovers, add 8 ounces of sliced mushrooms to the vegetable sauté for an extra umami boost. If you enjoy some heat, incorporate a diced jalapeño or a sprinkle of red pepper flakes. For a richer version, mix in 2-3 tablespoons of heavy cream along with the cream cheese.

Serviervorschläge

This hearty casserole stands perfectly well on its own, but pairs beautifully with a simple side salad dressed with olive oil and vinegar to cut through the richness. For a complete keto meal, serve alongside steamed broccoli or asparagus. If you're serving guests who aren't following a keto diet, you can offer warmed hoagie rolls on the side for them to make mini sandwiches with the casserole filling.
