Preheat your oven to 400°F (200°C). Gather all your ingredients while the oven heats up.

Arrange the refrigerated cheese tortellini, broccoli florets, and pre-cooked chicken breast on a large rimmed baking sheet.

Drizzle the olive oil over the ingredients and season with minced garlic, kosher salt, black pepper, and red pepper flakes. Toss to coat.

Spread the mixture into a single layer on the baking sheet to ensure optimal roasting.

Roast in the preheated oven for 18-20 minutes, checking until the tortellini is golden and the broccoli is tender.

Remove from the oven and sprinkle grated Parmesan cheese over the hot mixture.

Let the dish rest briefly before serving warm to savor all the flavors.
