1. Cut the steak into small bite-sized cubes and season with salt and pepper.

2. In a hot skillet, melt 2 tablespoons of butter and sear the steak in batches until browned on all sides. Remove and set aside.

3. Lower the heat, add 2 more tablespoons of butter, and sauté the minced garlic until fragrant. Pour garlic butter over the steak bites.

4. Boil shell pasta until al dente. Reserve 1/4 cup of pasta water and drain the rest.

5. In a saucepan over medium-low heat, combine heavy cream, cheddar cheese, and parmesan. Stir until melted and smooth.

6. Stir the pasta into the sauce until fully coated. Add crispy bacon and black pepper. If needed, use reserved pasta water to loosen the sauce.

7. Serve a generous helping of cheddar Alfredo shells, topped with the garlic butter steak bites. Garnish with extra parmesan or parsley if desired.
