Creamy Pesto Tortellini

There’s something comforting about a bowl of pasta that’s rich, saucy, and bright with fresh herbs. This Creamy Pesto Tortellini delivers that cozy, elevated pasta-night feeling with minimal fuss — tender cheese tortellini bathed in a silky pesto cream sauce made from a simple roux, broth, cream, and prepared pesto. It’s a weeknight winner, a potluck favorite, and perfect for anyone who loves creamy pasta with a pop of herbaceous flavor.

Before we dive in: this recipe uses pantry-friendly ingredients and comes together in one skillet with a few straightforward steps. The sauce is smooth and velvety thanks to a butter-and-flour base that’s gently cooked, then loosened with broth and cream. A modest amount of prepared pesto adds concentrated basil and garlic flavor without extra chopping, and just a touch of grated parmesan brings a savory finish. Fold in cooked tortellini, top with chopped fresh basil, and you have a dish that feels special without a lot of effort.

Why this recipe works

• Quick pasta: Cheese tortellini cooks fast, so dinner can be on the table in under 30 minutes.
• Balanced sauce: The roux gives the sauce body, while chicken or vegetable broth and cream create a smooth, pourable consistency that clings to the pasta.
• Flavor without fuss: Prepared pesto adds a bright, herby punch without extra prep time.
• Flexible: Use frozen or refrigerated tortellini — both work well — and swap broth types as needed.

Ingredients

• 2 tablespoons butter
• 2 tablespoons flour
• 1.5 cup heavy cream
• 1 cup chicken broth, or vegetable broth
• 1/3 cup pesto, prepared
• 1/4 cup grated parmesan cheese
• 38 ounces cheese tortellini, frozen or refrigerated (about 2 bags)
• chopped fresh basil

Equipment you’ll need

• Large pot for boiling tortellini
• Large skillet or sauté pan
• Whisk and wooden spoon or spatula
• Colander
• Measuring cups and spoons

Step-by-step instructions

Follow these steps to make smooth, saucy Creamy Pesto Tortellini. The directions mirror the ingredient order to keep everything consistent and easy to follow.

1. Bring water to a boil and cook the tortellini. Fill a large pot with water, add a pinch of salt, and bring it to a rolling boil. Add the 38 ounces cheese tortellini (frozen or refrigerated), stir gently to separate, and cook according to the package instructions until al dente. Fresh refrigerated tortellini typically takes less time than frozen; check a few pieces early so they don’t overcook. Once done, drain the tortellini in a colander and set aside while you make the sauce.
2. Make a roux with butter and flour. While the pasta cooks, place a large skillet over medium heat and add 2 tablespoons butter. Let the butter melt and foam but not brown. Sprinkle in 2 tablespoons flour and whisk continuously for 1 to 2 minutes until the mixture is smooth and turns slightly golden. This cooks out the raw flour taste and creates the thickening base for your sauce.
3. Slowly whisk in the liquids to form the sauce. Gradually pour in 1 cup chicken broth, or vegetable broth if you prefer, while whisking to prevent lumps. Once the broth is incorporated and slightly thickened, slowly add 1.5 cup heavy cream, whisking until the sauce is smooth. Continue cooking over medium-low heat until the sauce begins to thicken and coats the back of a spoon, about 3 to 5 minutes. Stir frequently to avoid scorching.
4. Stir in pesto for bright herb flavor. Remove the skillet from direct heat for a moment and add 1/3 cup prepared pesto. Stir until the pesto is fully blended into the cream sauce and you have an even green color throughout. Taste and adjust seasoning with a pinch of salt and pepper if needed.
5. Add parmesan for savory depth. Sprinkle in 1/4 cup grated parmesan cheese and stir until it melts into the sauce. Parmesan helps thicken the sauce slightly and adds a salty, savory note that complements the pesto and cream.
6. Toss the cooked tortellini in the sauce. Return the drained tortellini to the skillet and gently fold them into the pesto cream sauce. Use a wooden spoon or spatula to coat each piece evenly, taking care not to break the pasta. Warm everything together for 1 to 2 minutes so the tortellini absorb a bit of the sauce and the temperature is even throughout.
7. Finish with fresh basil and serve. Remove the pan from the heat and sprinkle chopped fresh basil over the top. Give the pasta a final gentle toss, then serve immediately while hot. A final grating of parmesan at the table is optional for extra cheesiness.

Taste and texture notes

This Creamy Pesto Tortellini should be luscious and slightly thick — the sauce clings to the pasta without being heavy or gummy. If the sauce becomes too thick after standing for a few minutes, stir in a splash of broth or cream to loosen it. If you want a brighter, herb-forward profile, stir in an extra tablespoon of pesto before serving. Conversely, if your pesto is particularly salty, hold back a little parmesan and adjust seasoning at the end.

Serving suggestions

• Serve with a crisp green salad dressed in lemon vinaigrette to cut through the richness.
• Pair with roasted vegetables, such as asparagus or cherry tomatoes, for color and texture contrast.
• Offer warm crusty bread for mopping up any leftover sauce.
• For a protein boost, serve alongside simply grilled chicken breasts or pan-seared fish.

Make-ahead and storage

You can prepare the sauce ahead of time and reheat gently before tossing with freshly cooked tortellini. Store leftover creamy pesto tortellini in an airtight container in the refrigerator for up to 3 days. Reheat on the stovetop over low heat, adding a splash of broth or cream to loosen the sauce as needed. Avoid microwaving for long stretches, as the cream sauce can separate; gentle stove reheating keeps the texture silky.

Ingredient swaps and tips

• If you prefer a lighter sauce, substitute half-and-half for the heavy cream, but the sauce will be slightly less rich and may require careful thickening.
• Use vegetable broth instead of chicken broth to keep the flavor vegetarian-friendly while still maintaining depth.
• Prepared pesto saves time; if you make your own, use a blend of fresh basil, olive oil, garlic, pine nuts or walnuts, and grated parmesan for best flavor.
• For a nuttier flavor note, stir in a tablespoon of toasted pine nuts or chopped walnuts just before serving.
• To keep the tortellini intact, be gentle when folding them into the sauce and avoid overcooking in the initial boiling step.

Common troubleshooting

• Too thin: Let the sauce simmer a little longer over low heat to reduce and thicken, or whisk in a small amount of additional flour mixed with butter (a mini roux) to thicken quickly.
• Too thick: Stir in extra broth or cream, a tablespoon at a time, until the desired consistency is reached.
• Grainy or separated sauce: This can happen if the sauce cooks at too high a heat after adding dairy. Remove from heat and whisk in a splash of broth to bring it back together. Reheat gently.
• Over-salted: If the sauce tastes too salty, add a splash of cream or a few tablespoons of unsalted broth to balance it, and consider adding more tortellini to dilute the intensity.

Why I love this recipe

Final thoughts

Make the dish your own by adjusting the pesto level, adding roasted veggies, or finishing with extra fresh basil.
