• 1 medium green bell pepper, diced
• 1 medium red bell pepper, diced
• 1 medium yellow onion, thinly sliced
• 2 cloves garlic, minced

Instructions

Step 1

Preheat oven to 375°F (190°C).

Step 2

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.

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.

Step 4

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

Step 5

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

Step 6

Return the beef to the skillet and mix everything together.

Step 7

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

Step 8

Sprinkle the provolone and mozzarella cheeses evenly over the top.

Step 9

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

Let rest for 5 minutes before serving.

Recipe FAQ

→ Can I freeze this casserole?

Yes, this freezes beautifully. Assemble the dish, wrap tightly, and freeze for up to 3 months. Thaw overnight in the refrigerator before baking.

→ What cut of beef works best?

Ribeye or sirloin steak sliced thin delivers the best flavor and tenderness. Flank steak also works well if thinly sliced against the grain.

→ Can I make this dairy-free?

Substitute dairy cheese with vegan alternatives and use coconut cream or dairy-free cream cheese for the creamy base element.

→ How do I prevent soggy cauliflower rice?

Squeeze excess moisture from frozen cauliflower rice after thawing. For fresh rice, avoid overcooking—it should remain slightly firm.

→ What vegetables can I add?

Sliced mushrooms, spinach, or zucchini blend well with the peppers and onions. Just adjust cooking time to ensure vegetables reach desired tenderness.
