Potato gnocchi with basil pesto is one of those combinations that feels generous without much effort. The gnocchi are cloud-soft, the pesto is sharp and grassy, and the whole thing comes together faster than most pasta dishes.
The only swap from a classic Ligurian plate is nutritional yeast in place of Parmigiano. It gives the same savoury depth without the dairy, and most people won’t notice the difference once it’s blended into the sauce.
I use store-bought gnocchi on weeknights and homemade when I have an hour. Both work. The pesto is where I’d put the effort – fresh basil, good olive oil, and a patient blitz in the food processor rather than a blender.
This is a weeknight plate that looks like you tried harder than you did, sitting comfortably alongside other satisfying vegan pasta recipes that punch above their effort.

Ingredient Notes
- Fresh basil: Use leaves only, no thick stems – stems make the pesto bitter. If fresh basil is unavailable, a 50/50 mix of fresh spinach and basil works without losing the colour.
- Pine nuts: Toast them dry in a skillet for 2 minutes until pale gold before blending – raw pine nuts taste flat. Walnuts or blanched almonds are cheaper substitutes that hold up well.
- Nutritional yeast: This replaces Parmigiano and adds the savoury, slightly nutty note the pesto needs. Start with 3 tablespoons and add more to taste.
- Extra-virgin olive oil: Use a mild, fruity oil here – a peppery Sicilian variety can overpower the basil. Add it slowly while the processor runs for a smoother emulsion.
- Potato gnocchi: Store-bought vacuum-packed gnocchi is fine and cooks in 2 minutes. If making homemade, use floury potatoes (Russet or Maris Piper) and keep the dough as dry as possible.
- Garlic: One small raw clove goes into the pesto. If raw garlic is sharp for your palate, blanch the clove in boiling water for 30 seconds first to mellow it.
Vegan Pesto Gnocchi Italian Style
Ingredients
Method
- Toast the pine nuts in a dry small skillet over medium heat for 2 minutes, stirring constantly, until pale gold. Tip onto a plate and leave to cool for 5 minutes.
- Add the basil leaves, cooled pine nuts, garlic, nutritional yeast, lemon juice, salt, and pepper to a food processor. Pulse 6 to 8 times until roughly chopped.
- With the processor running, pour in the olive oil in a slow, steady stream. Process until the pesto is smooth but still has visible flecks of basil. Taste and adjust salt or nutritional yeast. Set aside.
- Bring a large pot of water to a rolling boil. Add 1 tbsp fine sea salt - the water should taste lightly salty.
- Add the gnocchi and cook until they float to the surface, about 2 to 3 minutes for vacuum-packed. Do not stir more than once.
- Before draining, scoop out 60 ml of the starchy cooking water and reserve it in a small cup.
- Drain the gnocchi through a colander. Do not rinse.
- Transfer the drained gnocchi to a large bowl or back into the dry pot off the heat. Add the pesto immediately.
- Add the reserved cooking water 1 tbsp at a time, tossing gently until the pesto coats every gnocchi and the sauce looks glossy rather than thick. You may not need all the water.
- Divide between four warm bowls. Scatter over the extra toasted pine nuts and a few fresh basil leaves. Add a drizzle of olive oil if you like. Serve immediately.
Notes
Tips for Success
- Salt the gnocchi water as generously as you would for pasta – under-seasoned water makes the gnocchi taste bland no matter how good the pesto is.
- Scoop out 60 ml of gnocchi cooking water before draining and stir it into the pesto when tossing – it loosens the sauce and helps it coat evenly.
- Toss gnocchi with pesto off the heat to keep the basil vivid green – heat oxidises basil quickly and turns the sauce a dull khaki.
- Toast pine nuts in a dry skillet over medium heat, stirring constantly, and pull them the moment they turn pale gold – they go from done to burnt in under 30 seconds.
- Blend the pesto with a couple of ice cubes if it starts to warm up in the processor – cold pesto stays brighter and holds its colour longer.
Variations
- Swap basil for 100 g of fresh rocket and add a squeeze of lemon for a peppery, lighter sauce.
- Add 150 g of halved cherry tomatoes and a handful of baby spinach for a more substantial, colourful plate.
- Use sun-dried tomato pesto in place of basil pesto for a deeper, more intense Sicilian-style flavour.
Storage and Reheating
Store leftover gnocchi and pesto separately if possible. Dressed gnocchi keeps in an airtight container in the fridge for up to 2 days – the texture softens slightly but is still good.
The pesto alone keeps in a sealed jar in the fridge for up to 5 days. Press a thin layer of olive oil on top before sealing to stop the surface browning.
To reheat, add the gnocchi to a non-stick skillet over medium-low heat with a splash of water and stir gently for 2 to 3 minutes. Avoid the microwave if you can – it makes gnocchi rubbery.
Serving Suggestions
A simple rocket and tomato salad with a lemon and olive oil dressing is all this needs alongside. The bitterness of the rocket balances the richness of the pesto well.
For a more structured meal, serve with a slice of grilled sourdough to catch the extra sauce. A glass of chilled Vermentino or a light Pinot Grigio pairs cleanly with the herby, olive-oil-forward pesto.
If you’re serving this as a starter in an Italian-style multi-course meal, halve the portions and finish each plate with a few extra pine nuts and a grind of black pepper, then follow with a hearty naturally vegan Umbrian lentil stew as a second course.
FAQ
Why does my vegan pesto gnocchi turn out gluey?
Gluey gnocchi usually means they were overcooked or stirred too vigorously after draining. Pull them from the water as soon as they float to the surface and toss gently with the pesto, not in the pot.
Can I use frozen gnocchi instead of fresh or vacuum-packed for this recipe?
Yes – cook frozen gnocchi straight from the freezer in the boiling salted water. They take about 1 minute longer than fresh and tend to hold their shape well.
How do I know when the basil pesto is blended enough?
Stop blending when the texture is smooth but still has a little body – you should see flecks of basil rather than a perfectly uniform paste. Over-blending heats the basil and dulls the colour.
Can I use cashews instead of pine nuts in the dairy-free pesto?
Cashews work well and make the pesto slightly creamier. Soak them in cold water for 20 minutes first to help them blend smoothly and avoid a grainy texture.
Is this vegan gnocchi dish gluten-free?
Standard potato gnocchi contains wheat flour, so it’s not gluten-free by default. Look for gnocchi made with rice flour or potato starch only, which are widely available in most supermarkets.
What is the difference between Ligurian pesto gnocchi and this vegan version?
Traditional Ligurian pesto alla Genovese uses Parmigiano Reggiano and Pecorino, both of which are dairy, much like the cheese-forward approach you see in dishes such as spring asparagus pasta with Parmesan. This version replaces them with nutritional yeast, which gives a similar savoury depth without animal products.
