Pesto alla Genovese is the classic Italian basil pesto from Genoa, a fresh and aromatic sauce that can turn the simplest meal into something memorable. Made with basil, garlic, pine nuts, Parmigiano-Reggiano, and extra virgin olive oil, this traditional green sauce is bold, savory, and wonderfully versatile. Use it with pasta, spoon it over chicken or fish, swirl it into soup, or freeze it in small portions so you can enjoy the taste of summer basil long after the season ends.
Authentic pesto Genovese is traditionally prepared with a mortar and pestle. The word pesto comes from the Italian verb meaning “to pound,” which describes the original method of crushing basil, garlic, nuts, cheese, and oil into a fragrant paste. While that technique is beautiful and time-honored, it can be slow and is best suited to small batches. For everyday cooking, a food processor makes homemade basil pesto quick, easy, and consistent while still delivering fresh flavor and a vibrant green color.

Ingredients You’ll Need
- Fresh basil – The main ingredient in pesto alla Genovese. Use fresh leaves only and remove the stems for the best texture and flavor.
- Olive oil – Good-quality extra virgin olive oil gives the pesto richness and a smooth, silky consistency.
- Pine nuts – The traditional nut for classic basil pesto. They add a buttery texture and mild, nutty flavor.
- Cheese – Parmigiano-Reggiano is the classic choice. Grating it from a block gives the best flavor, though pre-grated cheese can work when time is short.
- Garlic – Use fresh garlic cloves. A little goes a long way, so keep it balanced rather than overpowering.
- Lemon juice (optional) – A small squeeze adds brightness and helps balance the richness of the cheese, nuts, and oil.
- Spinach (optional) – A small amount can help support the green color without changing the pesto too much.
Salt and pepper are added to taste. Exact measurements are included in the recipe card below.
Substitutions and Variations
- Cheese options – Parmigiano-Reggiano is classic, but Pecorino Fiore Sardo is also traditional in pesto alla Genovese. Grana Padano offers a similar nutty flavor, while Pecorino Romano is sharper and saltier.
- Herb additions – A little fresh Italian parsley or oregano can be added for a slightly different herbal note, while keeping basil as the main flavor.
- Nut substitutions – Pine nuts are traditional, but walnuts, almonds, or cashews can also be used. For a nut-free version, raw sunflower seeds are a practical alternative. The flavor will change slightly, but the sauce will still be delicious.
Chef’s Tip – The Trick to Bright Green Pesto is Blanching
For a vivid green pesto that keeps its color longer, blanch the basil leaves in boiling water for 5-10 seconds, then immediately transfer them to an ice bath. Drain well and pat completely dry before using. This brief blanching helps preserve the basil’s chlorophyll, keeping the pesto brighter in the refrigerator. It is an extra step, but it is worth it when presentation matters.
How to Make Pesto alla Genovese
Homemade pesto is quick to make. A food processor is the easiest tool for creating a smooth, vibrant basil sauce. A blender can also work, but use short pulses. Over-blending can warm the basil, dull the flavor, and make the pesto more likely to darken.
- With the food processor running, drop the garlic through the feed tube to mince it. Add the basil, pine nuts, cheese, olive oil, lemon juice if using, salt, and pepper. Pulse until the pesto reaches your preferred texture, either slightly rustic or smooth and creamy. Taste and adjust the seasoning as needed.
Chef’s Tip: If the pesto is too thin, add a little more basil, cheese, or nuts. If it is too thick, loosen it with a drizzle of olive oil, a squeeze of lemon juice, or a small splash of water.
Serving Suggestions
Pesto alla Genovese is best known as a pasta sauce, but it can do much more. Serve it close to room temperature so the basil, garlic, cheese, and olive oil flavors are at their best.
- Appetizers – Spoon a small amount onto deviled eggs, roasted portobello mushrooms, or mix it with Greek yogurt for a quick vegetable dip.
- Vegetables – Toss with roasted potatoes, green beans, grilled zucchini, or spoon over sliced tomatoes and mozzarella.
- Proteins – Serve over grilled chicken, seared salmon, shrimp, white fish, or simple roasted meat.
- Soups – Swirl into tomato soup, minestrone, or vegetable soup just before serving.
- Sandwiches – Spread on turkey sandwiches or panini, or mix with mayonnaise for a quick pesto aioli.
- Sides – Stir into mashed potatoes, warm rice, risotto, or grain bowls.
- Sauces – Warm gently with a splash of cream for an easy pesto cream sauce, especially good with salmon or pasta.
Storing & Freezing Basil Pesto
Homemade pesto is at its brightest and most aromatic on the day it is made. Store leftovers in a small airtight container that fits the pesto closely. For added protection, pour a thin layer of olive oil over the surface before sealing the container. This helps slow oxidation and keeps the pesto from turning brown too quickly. Refrigerate for up to 3 days.
To freeze basil pesto, portion it into ice cube trays or small freezer-safe containers in 2-tablespoon amounts. Once frozen solid, transfer the cubes to a freezer bag or airtight container. Frozen pesto keeps well for 2-3 months.
Keeping pesto cubes in the freezer is an easy way to add quick flavor to weeknight meals. Thaw a cube for pasta, stir one into risotto, or add it directly to soup for a fresh basil finish.
Chef’s Tip – Thawing Frozen Pesto
Do not microwave pesto, as high heat can dull the color and weaken the fresh basil flavor. Thaw frozen cubes at room temperature for 15-20 minutes or in the refrigerator for a few hours. For soup or simmering dishes, a frozen cube can be stirred directly into the pot. For pasta or risotto, thaw first so it blends smoothly.
