This creamy zucchini sauce is still my go-to comfort in a bowl—simple, velvety, and full of fresh garden flavor.

Ingredients You’ll Need

You won’t need anything fancy—just fresh ingredients and pantry staples:

• Zucchini – Use about 2½ pounds, halved and grated (keep the skin for color and nutrients)
• Olive oil – Go with a good extra virgin one for a bold base
• Sweet onion – Vidalia works great, adds mellow sweetness
• Garlic – Don’t skimp here—fresh and minced for full flavor
• Red pepper flakes – Just a pinch adds a subtle kick
• Fresh herbs – Basil, oregano, and mint bring a bright, layered taste
• Heavy cream – Or swap with coconut cream for dairy-free
• Romano cheese – Freshly grated makes a difference; try nutritional yeast for vegan twist
• Salt & black pepper – Essential for balance
• Reserved pasta water – Helps thin the sauce to silky perfection if needed

Optional but recommended: A sprinkle of love and a hungry appetite.

How to Make Creamy Zucchini Sauce

Step 1 – Prep the Zucchini

Start by halving the zucchini lengthwise and scooping out any large seeds. Grate it with the skin on (it softens beautifully while cooking). Lightly salt and let it sit for a few minutes, then squeeze out as much moisture as you can—it’s the secret to avoiding a watery sauce.

Step 2 – Sauté the Aromatics

Heat the olive oil in a wide skillet over medium heat. Add the diced onion and cook for about 3 minutes until it softens and turns golden. Stir in garlic and red pepper flakes, cooking for just a minute until fragrant.

Step 3 – Cook Down the Zucchini

Add the grated zucchini, salt, pepper, and half of the chopped herbs. Cover and simmer on low for about 15 minutes, stirring occasionally. It should look soft and almost melt into itself. This is where the magic begins.

Step 4 – Blend and Finish

Stir in the cream and remaining herbs. Add the cheese and keep the heat low. If you like a smoother sauce, use an immersion blender (just a few pulses). Add a splash of reserved pasta water to loosen it to your preferred consistency. Toss with cooked pasta or spoon over your favorite vegetables.

Tips for Best Results

• Squeeze that zucchini – Excess moisture is the enemy of creamy sauces
• Use freshly grated cheese – It melts better and adds a richer taste
• Blend if needed – For an ultra-silky texture, blending is your best friend
• Season at the end – Once everything’s combined, taste and tweak the salt and herbs

Serving Suggestions

This sauce doesn’t just belong on pasta (though it’s dreamy there):

• Toss with linguine or gnocchi for a quick dinner
• Spoon over grilled chicken or flaky white fish
• Use as a warm dip with crusty bread or veggie sticks
• Spread on sandwiches or use as a veggie-packed base for pizza
