Creamy Spinach Mushroom Tortellini with Caramelized Onions is a rich Italian pasta dish featuring tender tortellini in a luxurious sauce made with caramelized onions, sautéed mushrooms, fresh spinach, and heavy cream.
Caramelized onions can be prepared 1-2 days in advance and stored in the fridge for easier meal prep. Use refrigerated tortellini for best texture; frozen works but may require extra cooking time. For a spicier version, add a pinch of red pepper flakes with the mushrooms.
