Description

A rich and comforting pasta dish featuring tender cheese tortellini tossed in a creamy Parmesan sauce with caramelized onions, earthy mushrooms, and fresh spinach. This elegant yet easy vegetarian meal is perfect for busy weeknights.


Ingredients

  • 20 ounces cheese tortellini (fresh or refrigerated)
  • 2 tablespoons olive oil
  • 1 large yellow onion, thinly sliced
  • 8 ounces cremini or white mushrooms, sliced
  • 3 cloves garlic, minced
  • 3 cups fresh spinach
  • 1 cup heavy cream
  • 1/2 cup grated Parmesan cheese
  • 1/2 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon dried thyme
  • 1/4 teaspoon red pepper flakes (optional)

Instructions

  1. Bring a large pot of salted water to a boil and cook the tortellini according to package instructions. Drain and set aside.
  2. Heat olive oil in a large skillet over medium heat. Add the sliced onions and cook for 15–20 minutes, stirring often, until soft and caramelized.
  3. Add the sliced mushrooms and cook for 5–7 minutes until tender and moisture has evaporated.
  4. Stir in the minced garlic and cook for 1 minute until fragrant.
  5. Reduce heat slightly and pour in the heavy cream. Simmer gently for 3–4 minutes.
  6. Stir in Parmesan cheese, salt, black pepper, thyme, and red pepper flakes if using.
  7. Add fresh spinach and cook until wilted.
  8. Fold in the cooked tortellini and toss to coat evenly in the sauce. Simmer for 2–3 minutes, then serve warm.

Notes

  • Substitute half-and-half for a lighter version.
  • Add grilled chicken or shrimp for extra protein if desired.
  • A splash of white wine before adding cream enhances flavor depth.
  • Store leftovers in an airtight container for up to 3 days.
  • Reheat gently with a splash of milk or cream to loosen the sauce.
