This Zucchini Pasta Sauce can be tossed over any shape pasta! You can also use it to serve with ravioli or layer in a lasagna recipe. A comforting pasta sauce recipe that’s good for you, too!



  • 2 tablespoons olive oil and 2 tablespoons butter
  • 2 pounds zucchini, cut into a large dice
  • 1 large onion, cut into a large dice
  • 1 teaspoon kosher salt
  • Fresh black pepper to taste (start with at least 1 teaspoon)
  • 12 tablespoons chopped garlic (we like closer to 2)
  • 2 cups chicken broth
  • 1/2 cup heavy cream
  • 1 tablespoon chopped thyme (you can also add the thyme stems right into the sauce for a lighter flavor and then remove the stems before blending)
  • 1 bay leaf
  • 1/4 cup grated parmesan cheese
  • 2 tablespoon chopped fresh parsley
  • Garnish more parmesan cheese and fresh black pepper if desired.


  1. Add the olive oil and butter to a large sauce pan. Once the butter has melted, add the diced zucchini, onion and garlic and season with salt and pepper. Cook the vegetables, stirring occasionally, for 10 minutes until softened.
  2. Pour in the chicken broth, cream and then add the bay leaf and thyme. Stir and simmer the sauce over low heat, uncovered for 20 minutes.
  3. Remove the bay leaf and thyme stems from the sauce and then puree with a stick blender until smooth. Tilt the skillet so that the sauce doesn’t splatter, or alternately, you can let the sauce cool and then transfer to a blender.
  4. Stir in the fresh parmesan cheese and fresh parsley. Taste the sauce and adjust the seasonings if needed.

Recipe Notes

This pasta sauce will make more than enough for a whole pound of pasta. Add the sauce to your cooked pasta a little at a time and toss for desired consistency. Store extra sauce in a covered container for up to a week.

Frozen sauce can be defrosted and reheated on the stove top, whisking to bring the sauce back together and also adding a splash more cream if needed.
