Simple Yet Tasty Zucchini Mushroom Pasta

Not every pasta needs a cream sauce or a long-simmered tomato base to be worth eating. This zucchini mushroom pasta is proof of that.

A bowl of zucchini and mushroom pasta with green napkin and a fork in the background. — Vegetarian zucchini mushroom pasta with olive oil, garlic, and fresh herbs. No extras, just well-cooked vegetables and good pasta.

This pasta dish is made with the simplest possible basic ingredients — good olive oil, garlic, chili flakes, and two vegetables that work exceptionally well together in a hot pan. While zucchini adds a slightly crunchy texture to the dish, chestnut mushrooms bring an earthy, slightly meaty quality that makes it feel substantial despite the lack of meat.

I make this vegetarian dish when I want something satisfying without having to think too hard. It comes together in twenty minutes and leaves the kitchen smelling far better than the effort involved would suggest. It makes a weeknight vegetarian dinner that doesn’t feel like a compromise.

Why You’ll Love This Recipe

No cream, no tomatoes — just good olive oil doing its job. This is a garlic-and-oil-based pasta, which means the quality of the olive oil matters, and the flavor is clean and direct. It’s a different kind of richness from cream — lighter, more aromatic, and far less heavy on the stomach.
Twenty minutes from start to finish. Boil the pasta, fry the garlic, cook the mushrooms and zucchini, and toss everything together. There’s no simmering, no reducing, no waiting. This is genuinely fast weeknight food.
Completely vegetarian with no substitutions needed. No meat, no fish sauce, no hidden animal products beyond eggs in the pasta. As for the cheese, I use a vegetarian hard cheese that contains no rennet. But you can always choose Parmesan if you like.
A useful base recipe that works with almost any vegetable. The garlic-chili olive oil base suits courgette, aubergine, spinach, asparagus, broccoli, and sun-dried tomatoes — whatever needs using. Once you know the method, you can apply it to almost anything in the fridge.

Ingredients You Need

6 oz / 180g dried tagliatelle, cooked according to package instructions
7 oz / 200g chestnut mushrooms, sliced
1 medium zucchini, sliced
2 tablespoons olive oil
3 cloves garlic, crushed (approximately 1 tablespoon garlic paste)
1 teaspoon dried chili pepper flakes
1 teaspoon salt, or to taste
Grated vegetarian hard cheese, to finish generously
A generous handful of flat parsley, chopped

How to Make Zucchini Mushroom Pasta

Cook the pasta according to the package instructions. Drain and set aside. Reserve a small cup of pasta water before draining — useful for loosening the pasta if it dries out in the pan.
Build the garlic base by heating the olive oil in a skillet over medium heat. Add the garlic paste and fry until fragrant, about 30 seconds, stirring constantly to prevent burning.
Cook the mushrooms by adding the sliced chestnut mushrooms to the pan and stir-frying until they soften and begin to color slightly at the edges.
Add the zucchini and continue cooking for a few minutes until softened but still holding some shape.
Add the chili flakes and stir through the vegetables.
Toss in the pasta and stir continuously until all the tagliatelle is coated in the garlic chili oil and combined with the vegetables. If the pasta looks dry, add a splash of the reserved pasta water or a little extra olive oil.
Season with salt to taste and stir through.
Add the parsley and mix through the pasta.
Finish with cheese by grating a generous amount of hard cheese over the top. Mix well so the cheese melts into the hot pasta before serving.

Top Tips

Cook the zucchini separately from the mushrooms in the same pan. Add the zucchini after the mushrooms have taken on some color rather than at the same time. Different vegetables cook at different rates — mushrooms need longer and benefit from browning before the softer zucchini goes in.
Reserve pasta water every time, without exception. For oil-based pasta especially, a splash of starchy pasta water turns a dry, clumpy tangle of noodles into a glossy, evenly coated dish. Keep a cup back before you drain — you may not need it, but you’ll be glad it’s there.
Use the best olive oil you have. This recipe has no cream, no tomato sauce, no stock — the olive oil is the sauce. Its flavor comes through directly and makes a noticeable difference to the finished dish. A good extra-virgin olive oil, used generously, is worth it here.
Add the cheese while the pasta is still hot. Hard cheese melts on contact with hot pasta and integrates into the oil, coating the noodles. If the pasta has cooled, the cheese sits on top rather than melting through — less effective and less satisfying.

Substitutes and Variations

Mushroom alternatives: Portobello for a meatier texture, shiitake for a deeper umami flavor, oyster mushrooms for something more delicate. A mixed mushroom selection gives the most complex result and works particularly well in this simple oil-based sauce.
Zucchini alternatives: Aubergine, cut into small cubes and cooked slightly longer, gives a richer, denser result. Asparagus tips work well in spring. Tenderstem broccoli florets add a slightly bitter note that suits the garlic and chili well.
Add tomatoes: A handful of cherry tomatoes, added with the zucchini, burst slightly as they cook, adding acidity and juiciness that cut through the olive oil and make the sauce feel brighter.
Add sun-dried tomatoes: Roughly chopped sun-dried tomatoes stirred through with the parsley add a concentrated, slightly sweet intensity that works very well with mushrooms.
Make it creamier: Stir two tablespoons of crème fraîche, cream cheese, or a splash of double cream through the pasta just before serving. This will make creamy pasta like this sundried tomato pasta recipe.
Boost the umami: A teaspoon of soy sauce or a small amount of miso paste stirred into the pan with the mushrooms adds depth and an almost meaty savouriness without changing the overall character of the dish.

Storage

Refrigerator: Store in an airtight container for up to 2 days. The pasta will absorb the olive oil as it sits, so it may look dry when reheated. Reheat in a pan over medium heat with a splash of water and a drizzle of fresh olive oil, tossing until the pasta loosens and heats through evenly. Avoid the microwave — it makes tagliatelle sticky and uneven.

Freezer: Not recommended. Cooked pasta in an oil-based sauce loses its texture significantly on freezing. The zucchini becomes mushy, and the mushrooms deteriorate. Make this fresh — the twenty-minute cooking time makes it a practical weeknight option without needing to prep in advance.

Make-ahead: Cook the mushrooms and zucchini up to a day ahead, then refrigerate. Cook the pasta fresh when ready to eat, reheat the vegetables in the pan, and toss everything together. The whole assembly takes under ten minutes once the pasta is boiled.

What to Serve With

Crusty bread or garlic bread — for mopping up the garlic chili olive oil that settles at the bottom of the bowl. A non-negotiable alongside any oil-based pasta.
Simple rocket salad with lemon — dressed with lemon juice and extra-virgin olive oil —is ready in two minutes and adds a peppery bitterness that balances the earthiness of the mushrooms.
Extra chili flakes at the table — this pasta is mild to medium as written. A small dish of chili flakes alongside lets everyone adjust the heat without changing the dish for the table.
Soft-boiled egg — halved and placed on top, it adds protein and a rich yolk that runs into the garlic oil when broken, making the sauce even more coating and satisfying.

Common Questions Answered

What type of mushrooms work best in this pasta?

Chestnut mushrooms are used here because they have more flavor, a firmer texture, hold up better in a hot pan, and don’t release as much water. Portobello mushrooms give an even meatier result and work well sliced thickly. Shiitake mushrooms add a deeper, more umami-forward flavor. A mix of varieties is also excellent if you have them.

Can I use a different pasta shape?

Yes. Fettuccine is the closest alternative to tagliatelle and works in the same way. Spaghetti works well with olive oil-based sauces. Penne or rigatoni suit this style of sauce too — the ridges and tubes hold the garlic oil and catch the mushroom juices well. Avoid very small pasta shapes like orzo — they don’t suit a chunky vegetable stir-fry.

Can I add protein to this zucchini mushroom pasta?

Yes. Pan-fried chicken strips, sautéed prawns, and flaked tinned tuna can be stirred through at the end. For a vegetarian protein boost, white beans or chickpeas can be good options.

Can I make this pasta ahead of time?

The dish is best eaten immediately because the pasta absorbs the oil quickly as it sits and can become dry and clumped. The vegetables can be cooked ahead and refrigerated. Cook the pasta fresh when ready to eat, then toss it with the reheated vegetables in the pan, along with a splash of pasta water and extra olive oil.
