Ingredients You’ll Need

Vegetables & Fresh Ingredients

2 tablespoons olive oil (extra virgin gives the best flavor)
1 tablespoon unsalted butter (adds richness; skip or use more oil for dairy free)
1 medium yellow onion, chopped
2 cloves garlic, minced
2 pounds zucchini, chopped into half moons (about 4 medium zucchini)
1 small Yukon gold potato, peeled and diced (adds body and creaminess)
1 cup plain Greek yogurt, whole milk or 2%
Zest of 1 lemon (use organic if possible)
Juice of 1 lemon, about 3 tablespoons
3 tablespoons fresh dill, finely chopped, plus extra for garnish
2 tablespoons fresh parsley, chopped (optional but brightens the color)
1 teaspoon lemon zest for garnish (optional)

Pantry Staples & Seasoning

4 cups low sodium vegetable broth or chicken broth
- Use a good boxed brand like Pacific or Kettle & Fire for clean flavor.
½ to 1 teaspoon kosher salt, plus more to taste
½ teaspoon freshly ground black pepper
¼ teaspoon red pepper flakes (optional, for a gentle kick)
1 to 2 teaspoons honey or sugar (optional, balances acidity if needed)

Toppings & Garnishes

Extra Greek yogurt or a swirl of plain yogurt on top
Extra chopped dill and parsley
Drizzle of olive oil
Toasted pumpkin seeds or sunflower seeds for crunch
Croutons or small cubes of toasted bread

Substitutions & Variations

No Greek yogurt: Use plain regular yogurt and strain it in a fine mesh sieve for 15 minutes, or use sour cream for a richer taste.
Dairy free option: Skip butter and yogurt, use only olive oil, then finish with a splash of canned coconut milk and extra lemon.
No fresh dill: Use 1 to 1½ teaspoons dried dill; add it with the broth so it softens.
Low carb option: Skip the potato and simmer 5 minutes less; the soup will still taste creamy after blending.

Equipment List

Large pot or Dutch oven (at least 4 quart capacity)
Cutting board and sharp knife
Wooden spoon or heat safe spatula
Immersion blender or countertop blender
Microplane or fine grater for lemon zest
Ladle for serving

Tips & Tricks

Slice the zucchini into similar size pieces so they cook evenly and soften at the same time.
Sauté the onion until it turns translucent and sweet before you add zucchini, since that builds deep flavor.
Add garlic near the end of sautéing so it softens without burning and turning bitter.
Use low sodium broth so you control the salt level and avoid an overly salty soup.
Blend the soup very smooth for a silky texture, or pulse it a few times if you like a little texture.
Let the soup cool a few minutes before you stir in yogurt so it does not curdle.
Temper the yogurt by whisking in a ladle of warm soup, then pour that mixture back into the pot.
Taste after adding lemon and dill, then adjust salt and acidity so the flavors pop.
Chill a portion in the fridge and serve it cool on hot days with extra lemon zest on top.
Garnish right before serving so the herbs stay bright and the yogurt swirl looks pretty.

How to Make Zucchini Soup with Yogurt Lemon and Dill

Step 1: Prep the Vegetables

Chop the onion, mince the garlic, and slice the zucchini into half moons about ¼ inch thick. Peel and dice the potato into small cubes so it softens quickly. Zest the lemon first, then juice it, and chop the dill and parsley.

Step 2: Sauté the Aromatics

Heat the olive oil and butter in a large pot over medium heat. Add the onion and a pinch of salt, then cook 5 to 7 minutes until the onion turns soft and lightly golden at the edges. Stir in the garlic and cook 30 seconds until it smells fragrant.

Step 3: Cook the Zucchini and Potato

Add the chopped zucchini and potato to the pot. Stir to coat the vegetables in the oil, butter, and onion mixture. Cook 5 minutes, stirring occasionally, until the zucchini starts to soften and look glossy.

Step 4: Add Broth and Simmer

Pour in the broth and stir in ½ teaspoon salt, black pepper, and red pepper flakes if you use them. Bring the soup to a gentle boil, then lower the heat to maintain a steady simmer. Cook 12 to 15 minutes until the zucchini and potato feel very tender when you poke them with a fork.

Step 5: Blend the Soup

Turn off the heat and let the soup cool 5 minutes. Use an immersion blender to blend the soup directly in the pot until it turns very smooth and creamy. If you use a countertop blender, work in batches, fill it only halfway, vent the lid slightly, and hold a towel over the top so steam escapes safely.

Step 6: Add Yogurt, Lemon, and Dill

Scoop the Greek yogurt into a bowl and whisk in a ladle of warm soup to loosen it. Pour that mixture back into the pot and stir until the soup looks creamy and uniform. Add lemon zest, lemon juice, dill, and parsley, then taste and adjust salt, pepper, and lemon to your liking.

Step 7: Adjust Texture and Seasoning

Check the thickness of the soup. If it feels too thick, stir in a splash of broth or water until it reaches your preferred consistency. If it tastes too sharp from the lemon, stir in a teaspoon of honey or sugar to round it out.

Step 8: Serve and Garnish

Ladle the hot soup into bowls. Add a spoonful or swirl of yogurt on top, then sprinkle with extra dill, parsley, and lemon zest. Finish with a small drizzle of olive oil and a handful of toasted seeds or croutons for crunch.

What to Serve with Zucchini Soup with Yogurt Lemon and Dill

Serve this Zucchini Soup with Yogurt Lemon and Dill with warm crusty bread, garlic toast, or pita for dipping. A simple green salad with cucumbers, tomatoes, and a light vinaigrette pairs nicely with the lemon and dill flavors. You can also serve it with grilled chicken, baked salmon, or roasted chickpeas for extra protein. For kids, add a side of grilled cheese or quesadillas and call it a cozy dinner.

Storage Options

Cool the soup to room temperature, then store it in airtight containers in the fridge for up to 4 days.
Stir well before reheating, since the yogurt can thicken the soup as it chills.
Reheat gently on the stove over low to medium heat and avoid boiling so the yogurt stays smooth.
Freeze the soup without the yogurt for up to 3 months, then thaw, reheat, and stir in fresh yogurt, lemon, and dill right before serving.
If you freeze it with yogurt, expect a slightly grainy texture after thawing; blend it again to smooth it out as much as possible.
