Can I Use Fresh or Frozen Tortellini?

Yes! Fresh tortellini cooks in about 3-4 minutes, while frozen might need a minute or two more. Just make sure not to overcook, as they’ll continue to soften in the sauce. For best results, use cheese-filled tortellini to enhance the richness of the dish.

Ingredients for the Creamy French Onion Tortellini

Each ingredient in this dish contributes to its luxurious depth of flavor:

• 2 tablespoons unsalted butter: For sautéing and deepening the onions’ sweetness.

• 1 teaspoon fresh thyme leaves (or 1/2 tsp dried): Gives that classic French onion herb note.
• 1 tablespoon all-purpose flour: Slightly thickens the sauce.
• 1/2 cup dry white wine: Deglazes and adds acidity (optional, or use broth).
• 2 cups low-sodium beef or vegetable broth: Forms the savory base.
• 1 cup heavy cream: Makes the sauce creamy and indulgent.
• 1/2 teaspoon black pepper: For a little kick.

How to Make the Creamy French Onion Tortellini

Step 1: Caramelize the Onions

In a large skillet, heat the butter and olive oil over medium-low heat. Add the sliced onions, salt, and sugar. Cook, stirring frequently, for 20-25 minutes until the onions are deeply golden and caramelized.

Step 2: Build the Flavor Base

Stir in the minced garlic and thyme, cooking for 1 minute until fragrant. Sprinkle the flour over the onions and cook for another minute.

Step 3: Deglaze and Simmer

Pour in the white wine to deglaze the pan, scraping up any brown bits. Let it reduce for 2 minutes. Add the broth and bring to a simmer.

Step 4: Make It Creamy

Stir in the heavy cream and black pepper. Simmer for 3-4 minutes to thicken slightly.

Step 5: Add Tortellini and Cheese

Add the tortellini and cook according to package directions (typically 4-5 minutes for refrigerated). Once tender, stir in the shredded Gruyère until melted and smooth.

Step 6: Garnish and Serve

Top with chopped fresh herbs and an extra sprinkle of cheese, if desired. Serve hot.

Frequently Asked Questions

1. Can I make this ahead of time?
Yes, the caramelized onions and sauce can be made 1-2 days in advance. Store separately from the tortellini and combine when reheating.

2. Can I use a different cheese?
Gruyère is classic for its nutty flavor, but Swiss, mozzarella, or fontina work well too.

3. Is there a non-dairy option?
Use full-fat coconut milk and vegan butter. Nutritional yeast or vegan cheese can replace the Gruyère.

4. What if I don’t have wine?
Just replace it with an equal amount of broth and a splash of lemon juice for acidity.

5. How do I prevent the tortellini from getting mushy?
Cook them just until tender and serve immediately. They’ll continue to absorb sauce as they sit.
