Bring a large pot of salted water to a boil. Add the tortellini and cook according to the package instructions. Once cooked, drain and set aside.

In a large skillet, heat olive oil over medium heat. Add the ground beef and cook until browned, breaking it apart with a spoon, about 5-7 minutes. Drain excess fat if necessary.

To the skillet, add minced garlic, onion powder, salt, and pepper. Stir for about 1 minute until fragrant.

Lower the heat and pour in the heavy cream, stirring well. Gradually add the grated Parmesan cheese, letting it melt into the creamy mixture.

Add the cooked tortellini to the skillet, gently tossing to coat the pasta in the creamy sauce. Cook for an additional 2-3 minutes until everything is well combined and heated through.

Garnish with fresh parsley if desired and serve immediately.
