Zucchini Carbonara (Ready in 25 Minutes)
This zucchini carbonara is my favorite way to make a creamy, no-cream pasta when summer squash is piling up on the counter.
It tastes like the real deal—silky egg yolk and pecorino coat each strand of spaghetti, with salty pancetta and tender ribbons of zucchini in every forkful.
Why This Zucchini Carbonara Works
The zucchini slicks itself into the sauce, adding a little vegetable sweetness without watering things down.
I keep coming back to this because it’s just as quick as a regular carbonara but feels a little more like a complete dinner.
Ingredients
- 8 oz spaghetti: use bucatini or linguine if you prefer
- 2 medium zucchini: (about 6–7 oz each): shaved into thin ribbons with a vegetable peeler
- 4 oz pancetta, diced: or thick-cut bacon
- 3 large egg yolks: room temperature
- 1/2 cup finely grated Pecorino Romano cheese: plus more for serving
- 1/4 cup finely grated Parmesan cheese
- 1 tablespoon olive oil
- Freshly ground black pepper: be generous
- Salt: for cooking the pasta
Variations / Substitutions
- Pancetta swap: thick-cut bacon works well; the flavor will be a little smokier, so you might use a little less.
- Zucchini swap: yellow summer squash shaves into ribbons the same way and tastes just as mild.
- Cheese swap: use all Pecorino or all Parmesan if that’s what you have on hand—the sauce will still turn out rich and savory.
- Heat: add a pinch of red pepper flakes when you crisp the pancetta if you want a gentle kick.
- Vegetarian version: skip the pancetta and sauté 4 oz finely chopped cremini mushrooms in the olive oil until deeply browned; they bring a similar meaty note.

How to Make Zucchini Carbonara
Step 1: Shave the Zucchini
Run a vegetable peeler down the length of each zucchini to create long, thin ribbons. Stop when you reach the seedy, spongy center, which you can discard. You’ll get a neat pile of tender strips in about 2 minutes.
The ribbons should look like wide pappardelle—pliable but not paper-thin. If they’re too thin, they might fall apart in the pasta water.
Step 2: Crisp the Pancetta
Set a large skillet over medium heat, add the 1 tablespoon olive oil, and scatter in the 4 oz diced pancetta. Cook, stirring occasionally, for 5 to 7 minutes, until the bits are deeply golden and crunchy at the edges.
You’ll hear a steady sizzle as the fat renders out. Once the pancetta is crisp, scoop it out with a slotted spoon and leave the skillet on the stove, keeping a little of the rendered fat in the pan for flavor.
Step 3: Whisk the Egg Mixture
In a medium bowl, combine the 3 large egg yolks, the 1/2 cup Pecorino, the 1/4 cup Parmesan, and a heavy dose of freshly ground black pepper. Whisk for about 30 seconds until you have a thick, pale paste.
The mixture will look almost like a stiff lemon curd right now. That’s the base that will melt into a glossy sauce when you toss it with hot pasta.
Step 4: Boil the Spaghetti and Add the Zucchini
Bring a large pot of generously salted water to a rolling boil. Cook the 8 oz spaghetti according to the package for al dente—usually 8 to 10 minutes. During the last 30 seconds of cooking, drop in all the zucchini ribbons. They should turn bright green and soften just enough to wrap around a fork.
Before draining, scoop out 1 cup of the starchy pasta water and set it aside. Drain the spaghetti and zucchini together quickly, giving them a shake but leaving them a little wet.
Step 5: Toss and Serve
Return the drained pasta and zucchini to the dry pot, off the heat. Add the reserved pancetta, then pour the egg mixture over everything. Using tongs, toss vigorously, drizzling in the pasta water a little at a time. You’ll need about 1/2 cup total, added in splashes, until the sauce goes from thick paste to a velvety coat that clings to every strand.
The residual heat cooks the eggs softly—no scrambling, just a lush sheen. Plate the carbonara right away, shower each serving with extra Pecorino and a few more cracks of black pepper, and eat while the noodles are piping hot.
Tips for Silky Zucchini Carbonara
- Warm the eggs before you start.: Let the yolks sit on the counter for 10 minutes while you prep. Cold eggs can seize up when they hit hot pasta.
- Take the pan completely off the heat.: Once the spaghetti is drained, don’t put the pot back over the burner—even low residual heat from a warm hob can scramble the sauce.
- Season the pasta water like the sea.: It’s your only shot to season the noodles from the inside, and it brightens the whole dish.
- Keep some pancetta fat in the pan.: After you remove the cooked pancetta, tip out all but a thin slick of the rendered fat. That little bit adds a savory depth to the final toss.
Storing Leftover Zucchini Carbonara
- Refrigerate: Pack leftovers into an airtight container and store in the fridge for up to 2 days. The sauce will tighten up and the pasta will drink in moisture overnight, so the texture changes.
- Reheating: Warm it gently in a skillet over low heat with a splash of water or a little milk, stirring often. Go slowly—the eggs can scramble if the pan gets too hot.
- Serve cold: Straight from the fridge, it’s actually a nifty pasta salad. Let it come to cool room temperature and eat it as is.
What to Serve With Zucchini Carbonara
A crisp green salad with a sharp lemon vinaigrette cuts through the richness of the egg and cheese. For something more substantial, a hunk of garlic-rubbed toast or a glass of dry white wine like Verdicchio matches the salt and fat without overwhelming it.
Frequently Asked Questions
Can I use only zucchini noodles instead of spaghetti?
You can, but the sauce will likely turn watery because zucchini releases more liquid than pasta does. For the best texture, I stick with mostly spaghetti and just a handful of ribbons.
Is this recipe gluten-free?
The spaghetti is not, but you can swap in a gluten-free long pasta without changing the method. All the other ingredients are naturally gluten-free.
Can I make it vegetarian?
Yes, skip the pancetta and sauté 4 oz finely chopped cremini mushrooms in the olive oil until they’re deeply browned and almost crisp. They bring a similar savory punch.
My sauce clumped up—what went wrong?
The pot or pan was too hot when you added the egg mixture, or you didn’t toss quickly enough. Next time, pull the pot completely off the heat, add the egg off the stove, and drizzle the pasta water in slowly while stir-frying with tongs the whole time.
