Italian Zucchini Herb Pasta with Creamy Romano Sauce Recipe
Introduction
This Italian Zucchini Sauce is a fresh, creamy, and herb-packed alternative to traditional pasta sauces. Using shredded zucchini and a blend of fresh herbs, it delivers vibrant flavors with a smooth, comforting texture. Perfect for a light yet satisfying meal any time of year.

Ingredients
- 12 oz dry pasta of your choice
- 2 1/2 lb zucchini
- 3/4 cup extra-virgin olive oil
- 1 cup diced sweet onion (such as Vidalia)
- Pinch crushed red pepper flakes
- 1 1/2 tbsp minced fresh garlic
- 1 tsp kosher salt
- 1 tsp ground black pepper
- 2 tbsp chopped fresh basil
- 2 tbsp chopped fresh oregano
- 2 tbsp chopped fresh mint
- 1 cup heavy cream
- 3/4 cup finely grated Romano cheese
- 2 tbsp chopped fresh basil (to finish)
- 2 tbsp chopped fresh oregano (to finish)
- 2 tbsp chopped fresh mint (to finish)
Instructions
- Step 1: Bring a large pot of salted water to a boil. Add the dry pasta and cook according to package directions until al dente. Before draining, reserve one cup of pasta water for later. Drain the pasta and set aside. Toss the cooked pasta with a drizzle of olive oil to prevent sticking.
- Step 2: While the pasta cooks, trim the ends and halve the zucchinis lengthwise. Remove the seeds, then shred the zucchini using the large holes of a box grater or the shredder blade of a food processor. Set aside.
- Step 3: Heat the extra-virgin olive oil in a large skillet over medium-high heat. Add the diced sweet onion and sauté for about 3 minutes until softened. Add a pinch of crushed red pepper flakes and the minced garlic, cooking for one more minute until fragrant.
- Step 4: Add the shredded zucchini, kosher salt, black pepper, half of the fresh basil, oregano, and mint to the skillet. Increase heat to bring to a gentle bubble, then cover and reduce to medium-low. Cook for about 15 minutes, stirring occasionally.
- Step 5: Remove the cover and stir in the heavy cream along with the remaining fresh basil, oregano, and mint. Warm through and allow the sauce to thicken slightly.
- Step 6: Stir the finely grated Romano cheese into the hot sauce. If too thick, add reserved pasta water gradually until desired consistency is reached.
- Step 7: Toss the cooked pasta with the zucchini sauce or serve the sauce spooned over the pasta. Finish by scattering extra fresh basil, oregano, and mint on top before serving.
Tips & Variations
- For a spicier sauce, increase the crushed red pepper flakes to taste.
- Use fresh herbs for the best flavor, but dried can be substituted in smaller amounts if necessary.
- Try adding a squeeze of lemon juice at the end for extra brightness.
- Substitute Romano cheese with Parmesan if desired.
- To make it lighter, replace heavy cream with half-and-half or use a dairy-free alternative.
Storage
Store leftover zucchini sauce and pasta separately in airtight containers in the refrigerator for up to 3 days. Reheat gently on the stove over low heat, adding a splash of reserved pasta water or cream to loosen the sauce if it has thickened.
