Bring a large pot of salted water to a boil. Cook the tortellini according to package instructions until al dente. Drain and set aside.
In a large skillet, heat the olive oil over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant.
Pour in the heavy cream and stir well. Let it simmer for 2-3 minutes, allowing it to thicken slightly.
Reduce the heat to low, then add in the shredded mozzarella and grated Parmesan cheese. Stir continuously until the cheeses melt and the sauce is smooth.
Add the shredded chicken, steamed broccoli, onion powder, black pepper, and salt to the skillet, mixing everything together until well combined.
Gently fold in the cooked tortellini, ensuring they are coated in the cheesy sauce.
Cook for an additional 2-3 minutes, stirring occasionally, until everything is heated through.
Remove from heat, garnish with fresh parsley, and serve immediately.
Notes
Serve in a shallow bowl with extra Parmesan cheese and parsley.
