How to Make the Recipe

Step 1

Cook the pasta according to package instructions until al dente. Reserve 1 cup of pasta water and set aside. Drain the rest and keep the pasta warm.

Step 2

Trim and roughly chop the zucchini. In a large pan, heat the olive oil over medium heat. Add the onion and cook until soft and translucent, about 5 minutes.

Step 3

Add the garlic and red pepper flakes, cooking for another minute until fragrant. Then stir in the chopped zucchini.

Step 4

Season with salt and pepper, and cook uncovered over medium heat until the zucchini is very soft, about 15–20 minutes, stirring occasionally.

Step 5

Stir in half of the basil, mint, and oregano. Use an immersion blender or transfer the mixture to a blender and blend until smooth.

Step 6

Return the sauce to the pan and add the heavy cream. Stir well and bring to a gentle simmer.

Step 7

Add the cooked pasta and toss to coat, using reserved pasta water to loosen the sauce if needed.

Step 8

Finish with the remaining herbs and grated Romano cheese. Toss again and serve warm.

Tips for Making the Recipe

Use fresh herbs for maximum flavor—dried won’t have the same impact.
Cook the zucchini until fully soft before blending for the creamiest texture.
Use a good quality olive oil since it’s a key ingredient in the sauce’s base.
Blend the sauce in batches if using a traditional blender to avoid overflow.
Taste and adjust seasoning after blending—zucchini can absorb a lot of salt.

How to Serve

Serve the creamy zucchini sauce over your favorite pasta—rigatoni, penne, or spaghetti work well. It also makes a fantastic base for a white pizza, a side for grilled meats, or even as a creamy vegetable dip when chilled. Top with extra cheese and fresh herbs for a restaurant-quality presentation.
