In a large pot, cook the cheese tortellini according to the package instructions. Drain and set aside.
In a mixing bowl, combine the basil pesto, heavy cream, minced garlic, and half of the mozzarella cheese. Stir until well blended.
In a large baking dish, combine the cooked tortellini with the basil pesto mixture, halved cherry tomatoes, and baby spinach. Toss gently to combine everything evenly.
Season with salt and pepper to taste.
Sprinkle the remaining mozzarella cheese and grated Parmesan cheese over the top of the tortellini mixture.
Cover the baking dish with aluminum foil and bake in the preheated oven for 20 minutes.
Remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden brown.
Once done, remove from the oven and let it cool for a few minutes before serving.
Garnish with fresh basil leaves for added flavor and presentation.
Notes
