Ingredients You’ll Need

Fresh produce

2 tablespoons olive oil
1 medium yellow onion, chopped
2 cloves garlic, minced
1 ½ pounds zucchini, chopped into half moons (about 3 medium zucchini)
1 small Yukon gold potato, peeled and diced (adds creaminess without extra dairy)
Zest of 1 lemon (use organic if possible)
Juice of 1 lemon, plus more to taste
3 tablespoons fresh dill, finely chopped, plus extra for garnish
Optional: 1 small celery stalk, chopped, for extra flavor
Optional: 1 small carrot, chopped, for a touch of sweetness and color

Dairy and pantry items

1 cup plain Greek yogurt (whole milk for extra creaminess, or 2% for lighter texture)
3 to 4 cups low sodium vegetable broth or chicken broth
- Use a good quality boxed broth; I like brands with short ingredient lists and no added sugar.
2 tablespoons butter (or extra olive oil for a fully olive oil base)
½ teaspoon ground cumin (adds subtle warmth)
¼ teaspoon crushed red pepper flakes (optional, for gentle heat)
Salt and black pepper to taste

Substitutions and variations

Use sour cream instead of Greek yogurt if you prefer a richer, tangier finish.
Swap dill with fresh mint or parsley if you run out of dill, or use a mix of herbs.
Use lactose free yogurt if you need a low lactose option.
Use water plus 1 teaspoon better-than-bouillon style base if you keep that in your pantry and do not have boxed broth.

Equipment

Large pot or Dutch oven
Cutting board and sharp knife
Wooden spoon or spatula
Blender: immersion blender works best, or use a regular blender in batches
Microplane or fine grater for lemon zest
Ladle and serving bowls

Tips & Tricks

Salt in layers: season the onions, then the zucchini, then adjust again after blending.
Brown the onions lightly to build flavor, but stop before they turn dark, or the soup can taste bitter.
Cut zucchini into similar size pieces so they cook evenly and soften at the same time.
Add yogurt off the heat so it stays smooth and does not curdle.
Temper the yogurt by whisking in a ladle of warm soup before you stir it into the pot.
Blend the soup until very smooth for a restaurant style texture, or pulse briefly for a chunkier rustic version.
Adjust thickness by adding more broth if the soup feels too thick after blending.
Taste the soup after adding lemon juice and dill, then adjust salt and acid so the flavors pop.
Chill the soup completely before serving it cold, since flavors sharpen as it cools.
Garnish each bowl with a swirl of yogurt, a drizzle of olive oil, and extra dill for a pretty finish.

How to Make Zucchini Soup with Yogurt Lemon and Dill

Step 1: Sauté the aromatics

Heat the olive oil and butter in a large pot over medium heat. Add the chopped onion, celery, and carrot if you use them, along with a pinch of salt. Stir and cook until the onion turns soft and translucent and the vegetables smell sweet, about 5 to 7 minutes.

Add the minced garlic, cumin, and red pepper flakes. Stir and cook 30 to 60 seconds, just until the garlic smells fragrant.

Step 2: Add zucchini and potato

Add the chopped zucchini and diced potato to the pot. Sprinkle with another pinch of salt and some black pepper. Stir so the vegetables coat in the oil and aromatics.

Cook 3 to 4 minutes, stirring occasionally, so the zucchini starts to soften around the edges. This step builds flavor before you add the broth.

Step 3: Add broth and simmer

Pour in 3 cups of broth, starting with the lower amount so you can control thickness later. Stir everything, then bring the mixture to a gentle boil. Lower the heat to maintain a steady simmer.

Cover the pot partially and cook 12 to 15 minutes, until the potato and zucchini feel very tender when you pierce them with a fork. Taste the broth and adjust salt and pepper.

Step 4: Blend the soup

Turn off the heat. Use an immersion blender directly in the pot and blend until the soup turns smooth and velvety. Move the blender around the pot so you catch all the pieces.

If you use a regular blender, ladle the soup into the blender in batches, cover loosely, and blend until smooth. Return the blended soup to the pot and check the consistency, adding extra broth if you want a thinner soup.

Step 5: Add lemon, dill, and yogurt

Stir in the lemon zest, lemon juice, and chopped dill. Taste and adjust with more lemon juice or salt if the flavor needs more brightness. Let the soup cool for 5 minutes so it does not sit at a boil.

Scoop the Greek yogurt into a medium bowl. Whisk in a ladle of warm soup to loosen the yogurt, then pour that mixture back into the pot while you stir. Mix until the soup looks creamy and smooth.

Step 6: Adjust and serve

Taste again and tweak the seasoning with more salt, pepper, or lemon juice until the Zucchini Soup with Yogurt Lemon and Dill tastes balanced and bright. If you want it hotter, warm it gently over low heat, but do not let it boil so the yogurt stays silky. Ladle into bowls and garnish with extra yogurt, chopped dill, a drizzle of olive oil, and a grind of black pepper.

Serve warm, or chill it in the fridge for at least 2 hours if you want a cold zucchini yogurt soup. Stir before serving chilled, since it can thicken slightly as it rests.

What to Serve with Zucchini Soup with Yogurt Lemon and Dill

This Zucchini Soup with Yogurt Lemon and Dill pairs nicely with warm crusty bread, garlic toast, or simple pita wedges for dipping. You can add a crisp green salad with cucumbers, tomatoes, and feta to echo the fresh flavors in the soup. Grilled chicken, baked salmon, or roasted chickpeas work well on the side if you want extra protein. Serve it with iced tea, sparkling water with lemon, or a light herbal drink to keep the meal refreshing.

Storage Options

Store leftover Zucchini Soup with Yogurt Lemon and Dill in an airtight container in the fridge for up to 3 days.
Reheat gently on the stove over low heat, stirring often, and stop before it boils so the yogurt stays smooth.
You can freeze the soup before you add the yogurt for up to 2 months, then thaw, reheat, and stir in fresh yogurt, lemon, and dill.
If you freeze the soup with yogurt already mixed in, expect a slightly grainy texture after thawing, and blend it again to improve the texture.
