Preheat the oven to 400°F and line a large baking sheet with foil. Spray the foil with non-stick cooking spray.

Boil a pot of salted water according to package directions for the tortellini, but remove the pasta from the water 2-3 minutes before the suggested time (when the tortellini just begins to float).

Melt the butter in a small saucepan over low heat. Stir in the minced garlic and cook for 1-2 minutes, stirring often. The garlic should become aromatic but not brown.

Toss the tortellini with the garlic butter and half of the grated parmesan in a large bowl. Spread the mixture on the prepared baking sheet in a single layer.

Sprinkle the remaining grated parmesan over the tortellini.

Bake in the oven for 15-20 minutes or until the tortellini is lightly browned at the edges and the parmesan cheese is melted and browned.

Allow the baked tortellini to sit on the baking sheet for 3-5 minutes before serving.
