Step‑by‑Step Instructions for Creamy Zucchini Sauce
Step 1: Cook Pasta
Begin by bringing a large pot of salted water to a rolling boil over high heat. Once boiling, add your pasta and cook until al dente, following the package’s instructions, usually around 8-10 minutes. Just before draining, reserve one cup of the pasta water to help adjust your creamy zucchini sauce later for the perfect consistency.
Step 2: Prepare Zucchini
While the pasta cooks, prepare your zucchini by trimming off both ends and cutting it in half lengthwise. Use a box grater or food processor to shred the zucchini until you have about four cups of grated zucchini. Set aside the shredded zucchini, ensuring it’s ready to be added to the sauce in a moment.
Step 3: Sauté Aromatics
In a large skillet, heat about two tablespoons of extra-virgin olive oil over medium-high heat. Add the diced sweet onion and sauté for approximately three minutes, or until it appears softened and translucent. Next, incorporate the crushed red pepper flakes and minced garlic, stirring for an additional minute until fragrant and lightly golden.
Step 4: Cook Zucchini
Add the prepared shredded zucchini to the skillet, seasoning with kosher salt and freshly cracked black pepper to taste. Stir in half of your chopped fresh basil, oregano, and mint. Lower the heat to medium-low, cover the skillet with a lid, and let the zucchini simmer for about 15 minutes, stirring occasionally, until it’s tender and has released some moisture.
Step 5: Finish Sauce
Remove the lid from the skillet and gently stir in the heavy cream along with the remaining fresh herbs. Allow the mixture to heat through over medium heat. As the sauce warms, add finely grated Romano cheese, mixing until it melts and combines smoothly. If your sauce seems too thick, gradually stir in some reserved pasta water until it reaches your desired consistency.
Step 6: Combine and Serve
Once your creamy zucchini sauce is ready, toss it with the drained pasta in the skillet, making sure every strand is well-coated. Alternatively, you can spoon the sauce over the pasta when serving. Feel free to garnish with extra herbs for a fresh finish, and prepare to delight your family with this wholesome zucchini sauce!
