Creamy French Onion Tortellini Recipe

Next time you’re craving some true comfort food that warms both your body and soul, this is the easy pasta recipe to turn to! Onions are caramelized in butter with garlic and brown sugar before a bouquet of herbs and seasonings are mixed in to create even more flavor, and that’s just the start of this recipe! What really seals the deal for me is the perfect amount of gruyere cheese that gets stirred into the final product to make everything supremely cheesy. This one-pan recipe couldn’t be easier, cheesier, or more comforting!

Tortellini is one of my favorite ingredients to use in my kitchen. When you’re dreaming of a comforting pasta dinner, check out my recipes for Creamy Tomato Tortellini or Creamy Spinach Mushroom Tortellini!

 

What Else Can I Add to French Onion Tortellini?

This recipe is so versatile! You can add chicken, shrimp, or steak to the dish. You could caramelize the onions with portobello mushrooms for a rich, decadent pasta dish. You could also add broccoli or asparagus for a pop of fresh flavor. If you’re looking for a Cajun-style pasta, you can add Cajun seasonings and as much heat as you’d like!

How to Make Creamy French Onion Tortellini

1. Caramelize the onions. You’ll cook these for about 25 minutes total.  Don’t be worried about the amount of time, it’s pretty hands off, you just need to stir every once in a while.  The addition of brown sugar helps the onions caramelize faster.
2. Warm the broth. Add the broth, herbs, and seasonings to the skillet. Stir for 2-3 and bring to a simmer.
3. Cook the tortellini. Add the tortellini and heavy cream to the skillet. Cook for 3-4 minutes or until the pasta is cooked through. Stir often.
4. Make it cheesy. Remove the bay leaf, then add 1 cup of gruyère cheese. Stir until fully mixed in and the sauce is thick and cheesy!
5. Serve and enjoy! Top the pasta with 1 cup of gruyère cheese, then reduce the heat to low. Cover with a lid and let the cheese melt before serving.

Storing Creamy French Onion Tortellini

Once the dish cools to room temperature, you can store your leftovers in an airtight container in the fridge for up to 3 days. I do not recommend freezing French onion tortellini.

How to Make It Ahead of Time

While you can always reheat your leftovers in the fridge, they’re never as good as when the pasta has been freshly made. If you want to save yourself a little time, though, there is an easy way to prepare part of this pasta ahead of time and still have great results!

You can prepare the onions ahead of time. Caramelize them according to the instructions, then let them fully cool before storing in an airtight container in the fridge for up to 3 days.

Ingredient Notes for Creamy French Onion Tortellini

Onions – Yellow onions are the only ones I recommend using for this recipe because of their natural sweetness. I don’t recommend using white or red onions.
Garlic – Fresh garlic will create the best aroma and flavor. Avoid the pre-minced stuff if you can!
Beef Broth – Keep things less salty by using low-sodium broth.
Red Pepper Flakes – With the small amount listed in this recipe, this spice is present to add flavor, not a ton of heat. However, you can always sprinkle in more or less to fit your needs!
Heavy Cream – You can swap this with half and half, but you should note that your sauce won’t be as thick or creamy as it would be with heavy cream.
Gruyere Cheese – If you’re not a fan of gruyère cheese, you can replace it with American Swiss cheese, goat cheese or blue cheese.

  • Turn the heat to low. Add a lid and allow the pasta to remain warm for 3-5 minutes or until the cheese is melted.
