Courgette Pea and Pesto Soup

The first time I made this soup was during one of those chaotic Tuesday evenings when I had a mountain of courgettes from my garden box delivery and absolutely no energy for anything complicated. My kitchen smelled incredible within minutes of everything hitting the pan that bright green aroma of spring vegetables cooking together. Now its become my secret weapon for those moments when I want something that feels special but requires almost zero effort. The vibrant color alone makes people think I spent hours on it.

I served this to my skeptical dad who claims to hate soup as a meal and he went back for seconds. The way the pesto swirls through each bowl turns something simple into something that looks restaurant worthy. My friend Sarah now texts me every spring asking when Im going to make it again because her family keeps requesting it.

Ingredients

• 2 tbsp olive oil: Creates the foundation for sautéing your aromatics and adds a lovely richness to the base
• 1 medium onion finely chopped: Provides that essential sweet savory backbone that makes everything else taste better
• 2 garlic cloves minced: Fresh garlic is non negotiable here it bloomed briefly in the hot oil makes the whole kitchen smell amazing
• 3 medium courgettes diced: The real star of the show choose firm ones with vibrant green skin for the best flavor and color
• 250 g frozen or fresh peas: I always keep frozen peas in my freezer specifically for this recipe they add natural sweetness and that gorgeous bright green hue
• 1 medium potato peeled and diced: This might seem optional but its the secret to getting that silky restaurant texture without adding any cream
• 1 liter vegetable stock: Good quality stock makes such a difference here I make mine in big batches and freeze it in portions
• 1/2 tsp salt and 1/4 tsp black pepper: Season as you go and taste at the end courgettes need a bit more salt than you might expect
• 4 tbsp basil pesto: The finishing touch that transforms this from simple soup to something extraordinary homemade is worth the extra five minutes

Instructions

Sauté your aromatics:

Heat that olive oil in your largest saucepan over medium heat and toss in the chopped onion. Let it soften for about 4 minutes until it turns translucent and smells amazing.

Add the garlic:

Stir in your minced garlic and cook for just one minute until it becomes fragrant. Do not let it brown or it will turn bitter.

Soften the vegetables:

Add the diced courgettes and potato to the pan. Cook for 5 minutes stirring occasionally until they start to soften around the edges.

Simmer the base:

Pour in the vegetable stock and bring everything to a gentle boil. Reduce the heat and let it simmer for 10 minutes until the potato is almost tender.

Add the sweetness:

Stir in those peas and continue simmering for another 5 minutes. All your vegetables should be completely tender now.

Blend to perfection:

Remove the pan from heat and use your immersion blender right in the pot or transfer to a regular blender. Purée until completely smooth and silky.

Season and serve:

Taste and add more salt or pepper if needed. Reheat gently then ladle into bowls and swirl a tablespoon of pesto into each serving.

Save

This soup has become my go to for new neighbors friends who just had babies or anyone who needs a little comfort. Something about that bright green color and the familiar warmth of soup just makes people feel taken care of. Last spring I made vats of it for my daughters birthday lunch and even the kids went back for thirds.

Making It Your Own

The beauty of this recipe is how adaptable it is while still being delicious every time. I have made it with whatever greens are in my garden from spinach to asparagus and it always works. The basic method stays the same but you can play with the vegetables based on what looks good at the market.

Texture Secrets

Getting that perfectly smooth silky consistency is easier than you might think. The trick is letting the potato cook completely through before you blend everything together. I also find that letting the soup cool for just a few minutes before blending makes it smoother and less likely to separate.

Serving Suggestions

While this soup is beautiful enough to stand alone I love serving it with something crunchy on the side. A slice of really good crusty bread or some simple garlic toastlets people dip and soak up every last drop. For a lighter meal a crisp green salad with a sharp vinaigrette cuts through the richness perfectly.

• Make a double batch and freeze half for those nights when cooking feels impossible
• Top with a drizzle of good olive oil and some extra fresh basil if serving guests
• The soup thickens as it stands so thin with a splash of water or stock when reheating

Save

There is something so satisfying about putting a bowl of this vibrant green soup on the table. It manages to feel both comforting and light at the same time which is pretty much the perfect combination for any meal.

Recipe Q&A Section

Yes, frozen peas work perfectly in this soup. Add them directly to the simmering broth and cook for 5 minutes until tender. No need to thaw beforehand.

The soup stores well for 3-4 days in an airtight container. Reheat gently on the stove, adding a splash of water if needed. Add the pesto swirl just before serving.

→ Can I make this vegan?

Absolutely. Use dairy-free pesto (skip the Parmesan) and omit the crème fraîche or yogurt garnish. The soup remains creamy and satisfying without dairy.

→ What can I serve with this soup?

Crusty bread, garlic toast, or a simple green salad make excellent accompaniments. Grilled cheese sandwiches also pair wonderfully with the fresh, herbal flavors.

The potato adds natural creaminess and body without the need for heavy cream. It helps create a smooth, velvety texture while letting the vegetable flavors shine.
