Make this rich, velvety pesto pasta in a single pot for a quick, comforting weeknight dinner. This easy recipe delivers maximum flavor with minimal cleanup.

Ingredients

Scale
  • 1 pound pasta (penne or farfalle work well)
  • 4 cups water or vegetable broth
  • 1 cup heavy cream or half-and-half
  • 1/2 cup prepared basil pesto
  • 1/2 cup grated Parmesan cheese, plus more for serving
  • 1 clove garlic, minced
  • 1/4 teaspoon salt
  • 1/8 teaspoon black pepper

Instructions

  1. Place the pasta and water or broth into a large pot or Dutch oven. Bring the liquid to a boil over high heat.
  2. Once boiling, reduce the heat to medium-low, cover the pot, and cook for 10 to 12 minutes, or until the pasta is nearly tender. Stir occasionally to prevent sticking.
  3. Remove the pot from the heat. Stir in the heavy cream, basil pesto, Parmesan cheese, minced garlic, salt, and pepper.
  4. Stir continuously until the cheese melts and the sauce becomes smooth and creamy. If the sauce seems too thick, add a splash of hot water or reserved pasta cooking liquid until you reach your desired consistency.
  5. Serve immediately. Top each serving with extra Parmesan cheese for a satisfying finish.

Notes

  • For a heartier meal, you can add 1 cup of cooked, shredded chicken or sautéed shrimp during the final mixing step.
  • If you prefer a brighter flavor, add 1 teaspoon of fresh lemon zest when you add the salt and pepper.
  • This recipe is naturally vegetarian. Use gluten-free pasta to make it a gluten free option.
