1 pound pasta (spaghetti, linguine, or fettuccine work best)
2 large zucchini (about 1.5 pounds), sliced into 1/4-inch thick rounds
1 large yellow onion, thinly sliced
4 cloves garlic, minced
1/4 cup olive oil, extra virgin
2 tablespoons unsalted butter
1/2 cup vegetable broth or reserved pasta water
1/4 cup grated Parmesan cheese, plus more for serving
2 tablespoons chopped fresh basil, plus more for garnish
1 teaspoon red pepper flakes (optional)
Salt and freshly ground black pepper, to taste
1/4 cup toasted pine nuts (optional, for garnish)

directions

1. Prep the vegetables: Wash zucchini and slice into 1/4-inch rounds. Thinly slice onion and mince garlic.

2. Caramelize zucchini and onions: In a large skillet, heat olive oil and butter over medium heat. Add sliced onions and a pinch of salt. Cook 8–10 minutes until soft and translucent.

3. Add zucchini: Stir in zucchini, season with salt and pepper. Cook for 20–25 minutes, stirring occasionally, until deep golden and caramelized. Add broth or water if it starts to stick.

4. Add garlic and spices: Add garlic and red pepper flakes, if using. Cook 1–2 minutes until fragrant. Deglaze pan with white wine, if using, scraping up browned bits. Let wine reduce for 1–2 minutes.

5. Cook the pasta: Meanwhile, bring a large pot of salted water to a boil. Cook pasta until al dente. Reserve 1/2 cup pasta water and drain.

6. Combine pasta and sauce: Add pasta to skillet with caramelized vegetables. Pour in vegetable broth or reserved pasta water. Toss to coat well.

7. Finish with cheese and herbs: Add Parmesan cheese and stir until melted and creamy. Adjust consistency with more liquid if needed. Stir in chopped fresh basil.

8. Serve: Taste and adjust seasoning. Serve hot, garnished with extra Parmesan, basil, and toasted pine nuts if desired.

FAQs

Can I use other types of pasta?

Yes, spaghetti, linguine, fettuccine, or even penne or rigatoni work well with this dish.

How do I get the zucchini caramelized properly?

Be patient and don’t overcrowd the skillet. Stir occasionally and let the zucchini develop deep color and sweetness over medium heat.

Can I make this dish vegan?

Yes, use plant-based butter and vegan Parmesan, and ensure the pasta is egg-free.

What can I substitute for pine nuts?

You can use chopped walnuts, almonds, or sunflower seeds—or leave them out entirely.

Can I add more vegetables?

Absolutely. Bell peppers, mushrooms, eggplant, or spinach all pair well with the flavors in this dish.

How do I prevent the pasta from drying out?

Reserve pasta water and add as needed while tossing the pasta to keep everything creamy and well coated.

Can I make this ahead of time?

It’s best enjoyed fresh, but you can prepare the caramelized zucchini and onions in advance and store them refrigerated for up to 2 days.

What if I don’t have fresh basil?

Use dried basil or substitute with other fresh herbs like parsley or thyme.

Can I use zucchini noodles instead of pasta?

Yes, but reduce the broth or pasta water and cook just long enough to heat through, as zucchini noodles release moisture.
