Cook the Tortellini:
Boil the tortellini according to the package directions. Drain and set aside.
Brown the Beef:
In a large skillet over medium heat, cook the ground beef until browned and fully cooked, breaking it up as it cooks. Drain any excess grease.
Add Aromatics:
Stir in chopped onion and minced garlic. Sauté for 2–3 minutes until soft and fragrant.
Spice It Up:
Add chili powder, cumin, paprika, salt, and black pepper. Cook for another minute to toast the spices.
Add Sauce and Pasta:
Pour in the enchilada sauce and simmer for 5 minutes. Add the cooked tortellini and stir until well coated in the sauce.
Melt the Cheese:
Top the skillet with mozzarella and cheddar. Cover and let sit over low heat for 2–3 minutes, until the cheese is melted and gooey.
Creamy Finish:
Remove from heat, stir in the sour cream for added creaminess, and sprinkle with chopped cilantro if desired.
