- Budget-friendly: Uses everyday ingredients you probably already have in your cupboards.
Ingredients You’ll Need
- 400g dried spaghetti or linguine
- 3 medium courgettes (zucchini), spiralised or julienned
- 4 cloves garlic, finely minced
- 2 tablespoons olive oil
- 1 tablespoon unsalted butter
- Juice and zest of 1 large lemon
- 100ml chicken or vegetable stock
- 50g grated Parmesan cheese (or vegetarian alternative)
- Salt and freshly ground black pepper, to taste
- Handful of fresh basil leaves, torn
- Optional: pinch of red pepper flakes
Tip: Use a good-quality Parmesan here—it melts into the sauce and gives it that silky, luxurious texture. Pre-grated cheese often contains anti-caking agents that stop it from emulsifying properly.
How to Make Zucchini Pasta Lemon Garlic Sauce
- Bring a large pot of salted water to a rolling boil. Add your pasta and cook according to package directions until al dente. Reserve about 200ml of the starchy pasta water before draining—it’s liquid gold for the sauce.
- While the pasta cooks, heat the olive oil and butter in a large frying pan over medium heat. When the butter starts to foam and you hear a gentle sizzle, add the minced garlic. Cook for 30 seconds until fragrant—you’ll smell that sweet, nutty aroma immediately.
- Add the spiralised courgettes to the pan. Toss them with tongs for 2-3 minutes. They should soften slightly but still hold their shape—look for a bright green colour and a slight sheen from the oil. Don’t let them go mushy.
- Pour in the lemon juice and zest, then add the stock. Stir everything together and let it bubble for 1 minute. You’ll see the liquid reduce slightly and thicken—the smell of lemon and garlic will fill your kitchen.
- Add the drained pasta directly into the frying pan with the courgette mixture. Sprinkle over the Parmesan cheese and toss everything vigorously with tongs. If the sauce seems too thick, add a splash of the reserved pasta water—it should coat each strand of pasta in a glossy, creamy layer.
- Taste and adjust seasoning with salt and pepper. Tear the fresh basil leaves over the top and toss once more. Serve immediately while the pasta is still steaming.
Tips From My Kitchen
- Don’t overcook the courgettes: They only need 2-3 minutes in the pan. Overcooking releases too much water, making your sauce watery and the courgettes mushy. Keep them bright green and slightly firm to the bite.
- Reserve more pasta water than you think you need: I always save about 200ml, even if I only use half. The starch in the water helps emulsify the cheese and butter into a silky sauce that clings to every strand of pasta.
- Make the sauce ahead of time: Cook the courgettes, garlic, lemon, and stock together, then cool and refrigerate for up to 3 days. When you’re ready to serve, reheat the sauce gently, cook fresh pasta, and toss together—dinner in 10 minutes.
- Use a microplane for the garlic and lemon zest: Finely grated garlic melts into the sauce rather than leaving chunky bits, and lemon zest releases more aromatic oils when it’s fine. It makes a noticeable difference.
- Double the recipe for leftovers: This pasta is just as good cold the next day. Toss it with a little extra olive oil and lemon juice, and you’ve got a fantastic lunch straight from the fridge.
Equipment You’ll Need
- Large pot for boiling
- Colander
- Large frying pan
- Tongs or pasta fork
- Spiraliser or julienne peeler
- Microplane or fine grater
Common Mistakes to Avoid
- Overcrowding the pan: If you add too many courgettes at once, they’ll steam instead of sauté, turning watery and bland. Cook them in a single layer, working in batches if needed.
- Wrong temperature: Keep the heat at medium, not high. High heat burns the garlic before the courgettes have a chance to soften, leaving a bitter taste. Medium heat lets everything cook gently and evenly.
- Skipping the rest time: After tossing the pasta with the sauce, let it sit in the pan for 30 seconds off the heat. This allows the starch and cheese to bind together, creating that glossy, restaurant-quality finish.
Delicious Variations to Try
- Spicy Version: Add a pinch of red pepper flakes along with the garlic, or stir in a finely chopped fresh chilli for a kick of heat that cuts through the lemon.
- Vegetarian/Vegan Option: Swap the Parmesan for a vegan hard cheese or nutritional yeast, and use vegetable stock instead of chicken. The lemon and garlic are strong enough to carry the flavour beautifully.
- Different Protein: Toss in some shredded cooked chicken or pan-fried prawns right at the end. For a meatier option, try thinly sliced beef strips cooked quickly in the same pan before adding the courgettes.
What to Serve With Zucchini Pasta Lemon Garlic Sauce

Frequently Asked Questions
Can I use regular pasta instead of spiralised zucchini?
Absolutely. This recipe works beautifully with any pasta shape. Just follow the same steps, adding the cooked pasta directly to the courgette mixture. The courgettes will still add great texture and nutrition without needing a spiraliser.
How do I store leftovers?
Store in an airtight container in the fridge for up to 3 days. The pasta will absorb some of the sauce overnight, so when reheating, add a splash of water or stock and toss over medium heat until it’s glossy again.
Can I freeze this dish?
I don’t recommend freezing the assembled dish, as the courgettes become watery when thawed. However, you can freeze the lemon garlic sauce (without the pasta) for up to 2 months. Thaw overnight, then cook fresh pasta and toss together.
What if I don’t have a spiraliser?
Use a julienne peeler to cut the courgettes into thin strips, or simply slice them into thin rounds with a sharp knife. The texture will be slightly different, but the flavour will be just as good.
Can I make this gluten-free?
Yes, simply swap the regular pasta for your favourite gluten-free variety. Rice or corn-based pasta works well here. Just be careful not to overcook it, as gluten-free pasta can turn mushy quickly. Reserve extra pasta water to adjust the sauce consistency.
