Step 1: Sear the Steak
- Heat olive oil in a skillet over medium-high heat.
- Add the sliced steak and season with salt and pepper. Sear for 2–3 minutes on each side until browned. Remove from the skillet and set aside.
Step 2: Sauté the Vegetables
- In the same skillet, add the onions and bell peppers. Sauté for 5–7 minutes until softened and slightly caramelized.
- Stir in the minced garlic and cook for an additional minute. Remove from heat.
Step 3: Prepare the Crockpot
- Lightly grease the inside of your crockpot.
- Add the seared steak and sautéed vegetables to the bottom of the crockpot.
- Sprinkle the garlic powder, smoked paprika, and Worcestershire sauce over the mixture.
Step 4: Add the Liquid and Pasta
- Pour the beef broth and heavy cream over the steak and vegetables.
- Stir in the uncooked pasta, ensuring it is submerged in the liquid for even cooking.
Step 5: Slow Cook
- Cover and cook on low for 2–3 hours or high for 1–2 hours. Stir occasionally to prevent sticking and ensure even cooking.
Step 6: Add the Cheese
- Once the pasta is tender, stir in the provolone, mozzarella, and Parmesan cheeses.
- Mix until the cheese is fully melted and creates a creamy sauce.
Step 7: Serve
- Taste and adjust seasoning with salt and pepper if needed.
- Serve hot, garnished with fresh parsley and a sprinkle of crushed red pepper flakes for a spicy kick.
Storage and Reheating
- Refrigerate: Store in an airtight container for up to 3 days.
- Reheat: Warm in the microwave or a skillet with a splash of milk to refresh the sauce’s creaminess.
Tips for Success
