Making Garlic Butter Steak Tips with Cheesy Rigatoni is a straightforward process. Follow these steps for delicious results:

1. Cook the Pasta: Bring a large pot of salted water to a boil. Add rigatoni and cook according to package instructions until al dente. Drain and set aside.
2. Season the Steak: Pat the steak tips dry with paper towels. Season generously with salt and pepper.
3. Sear the Steak: In a large skillet over medium-high heat, heat olive oil. Add the seasoned steak tips in a single layer and sear for about 2-3 minutes on each side until brown. Remove from the skillet and set aside.
4. Prepare the Garlic Butter: In the same skillet, add the butter. Once melted, stir in the minced garlic and thyme. Sauté for about 1 minute until fragrant.
5. Deglaze the Pan: Pour in the beef broth, scraping any browned bits from the bottom of the pan. Let it simmer for a couple of minutes until reduced slightly.
6. Combine Ingredients: Return the steak tips to the skillet and toss to coat them in the garlic butter sauce. Remove from heat.
7. Make the Cheese Sauce: In a medium pot over low heat, combine the heavy cream, mozzarella, and Parmesan. Stir continuously until the cheese is melted and the sauce is creamy.
8. Combine Pasta and Sauce: Add the drained rigatoni to the cheese sauce, mixing well to ensure it is fully coated.
9. Serve: Place a generous portion of cheesy rigatoni onto a plate. Top with garlic butter steak tips and garnish with chopped parsley.
