How to Make Green Pesto Minestrone Soup

Sauté the Aromatics

Heat the olive oil in a large pot or Dutch oven over medium-high heat.

Add the diced onion and celery. Sauté for about 3 minutes, stirring occasionally, until the vegetables soften and begin to brown slightly.

Add the minced garlic and cook for another minute, just until fragrant.

Add the Vegetables and Beans

Add the diced zucchini, shredded kale, green beans, drained chickpeas, and cannellini beans.

Stir everything together, then pour in the chicken stock or vegetable broth.

For a vegetarian version, use vegetable broth. If you want the soup to be vegan, also make sure your pesto is vegan.

Cook the Pasta

Bring the soup to a boil.

Stir in the small pasta, then cover the pot and reduce the heat to low.

Simmer for approximately 10 minutes, or until the pasta is tender.

Keep an eye on the pasta because cooking time can vary depending on the type and size you use.

Add the Pesto

Once the pasta is cooked, turn off the heat.

Stir in the pesto and season the soup with kosher salt and freshly ground black pepper.

Taste before adding too much salt because the broth and pesto can already contain a fair amount of salt.

Make It Creamier

For a thicker, more substantial texture, use an immersion blender to pulse the soup several times.

You don’t need to puree the entire soup. A few quick pulses will break down some of the beans and vegetables and naturally add body to the broth while leaving plenty of texture.

Serve

Ladle the soup into bowls and finish each serving with a drizzle of olive oil, freshly grated Parmesan or Romano cheese, and freshly ground black pepper.

For an extra-bright finish, serve with lemon wedges and squeeze a little fresh lemon juice into each bowl.

Tips for Success

• Add pesto at the end: Turning off the heat before stirring in the pesto helps preserve its fresh flavor and vibrant color.
• Choose small pasta: Tiny shapes such as fregola or acini de pepe work especially well in soup.
• Watch the salt: Pesto, broth, and cheese can all be salty, so taste before adding additional seasoning.
• Don’t overcook the vegetables: Simmer just until the pasta is tender so the vegetables retain some texture.
• Use frozen green beans: They work perfectly well when fresh green beans aren’t available.
• Pulse for extra body: A few quick pulses with an immersion blender can make the broth thicker without turning the soup completely smooth.
• Add lemon: A squeeze of lemon is particularly helpful when your pesto doesn’t already contain lemon.

Equipment Needed

• Large pot or Dutch oven
• Wooden spoon or silicone spatula
• Sharp knife
• Cutting board
• Measuring cups and spoons
• Immersion blender, optional
• Ladle

Recipe Variations

Vegetarian Green Minestrone

Use vegetable broth instead of chicken broth. This simple swap makes the soup vegetarian while keeping all of its fresh, hearty flavor.

Vegan Pesto Minestrone

Use vegetable broth and vegan pesto. Skip the Parmesan or replace it with your favorite dairy-free Parmesan alternative.

Gluten-Free Green Minestrone

Replace the pasta with quinoa, rice, or another gluten-free grain. Check your broth and pesto labels as well to make sure they are gluten-free.

Green Minestrone With Parmesan

Add a Parmesan rind to the pot while the soup simmers. It adds a delicious salty, savory, umami flavor. Remove the rind before serving.

Extra-Protein Minestrone

Add additional chickpeas or cannellini beans for an even heartier bowl. You can also add white beans or cooked shredded chicken if you’re not keeping the recipe vegetarian.

Serving Suggestions

This green pesto soup is satisfying on its own, but a few simple sides can turn it into an even more complete meal.

Serve it with:

• Crusty sourdough bread
• Garlic bread
• Toasted baguette
• Italian bread
• A simple green salad
• Roasted vegetables
• Bruschetta
• Freshly grated Parmesan or Romano cheese

For a cozy dinner, serve a steaming bowl of soup with crusty bread for dipping into the flavorful pesto-infused broth.
