Step 1: Bring a large pot of salted water to a boil. Add the rotini pasta and cook according to package directions until al dente. Drain and set aside.

Step 2: While the pasta cooks, heat olive oil in a large skillet over medium heat. Add the ground beef, breaking it apart as it cooks, and brown it fully. Drain any excess grease.

Step 3: Season the beef with garlic powder, onion powder, Italian seasoning, crushed red pepper flakes (if using), salt, and pepper. Stir to combine well.

Step 4: Pour the marinara sauce into the skillet with the beef. Stir everything together and let it simmer on low heat for 5–7 minutes, allowing the flavors to meld beautifully.

Step 5: Add the cubed Velveeta cheese and stir until it’s completely melted and the sauce is thick, creamy, and cheesy.

Step 6: Add the cooked rotini pasta to the skillet and toss gently to coat every piece in that delicious cheesy beef marinara sauce.

Step 7: Sprinkle the shredded mozzarella evenly over the top. Cover and let sit for 2–3 minutes until the cheese melts. For a bubbly golden crust, pop the skillet under the broiler for 2–3 minutes (watch closely!).

Step 8: Garnish with chopped parsley or basil, serve warm, and enjoy that rich, comforting pasta goodness.
