Ingredients You’ll Need

Vegetables and aromatics

• 2 tablespoons olive oil
• 1 tablespoon unsalted butter (optional, for extra richness)
• 1 medium yellow onion, diced
• 2 cloves garlic, minced
• 1 ½ to 2 pounds zucchini, sliced into half-moons (about 4 medium zucchini)
• 1 small Yukon gold potato, peeled and diced (adds creaminess without extra dairy)
• ½ teaspoon kosher salt, plus more to taste
• ¼ teaspoon freshly ground black pepper

Liquids and flavor boosters

• 4 cups low-sodium vegetable broth or chicken broth
  • Use a good boxed brand with clean ingredients and low sodium so you control seasoning.
• ½ cup plain Greek yogurt, whole milk or 2%
  • Whole milk yogurt gives the creamiest texture.
• 1 teaspoon lemon zest (from 1 lemon)
• 2 to 3 tablespoons fresh lemon juice, to taste
• 2 to 3 tablespoons fresh dill, finely chopped, plus extra for garnish
• 1 to 2 tablespoons fresh parsley, chopped (optional, for extra green flavor)

Optional toppings

• Extra Greek yogurt or a swirl of plain unsweetened yogurt
• Drizzle of olive oil
• Extra chopped dill or parsley
• Crushed red pepper flakes for a little heat
• Toasted pumpkin seeds or pine nuts for crunch

Pantry shortcuts and substitutions

• Use frozen zucchini if fresh zucchini costs too much or looks tired. Thaw and drain it well before cooking.
• Replace the potato with ¼ cup raw cashews soaked in hot water for 20 minutes if you avoid potatoes.
• Swap Greek yogurt with plain regular yogurt and reduce broth slightly to keep the soup thick.
• Use dried dill if you cannot find fresh. Start with 1 to 1 ½ teaspoons and adjust to taste.

Equipment list

• Large pot or Dutch oven
• Cutting board and sharp knife
• Wooden spoon or spatula
• Blender: 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 blend smoothly.
• Sauté the onion and garlic until they turn soft and fragrant, not dark, to keep the soup flavor gentle and sweet.
• Add salt in layers while you cook instead of all at once so the flavors stay balanced.
• Let the soup cool a bit before blending so the hot liquid does not splatter.
• Blend the soup very smooth for a silky restaurant-style texture, or pulse briefly if you like a little texture.
• Stir the yogurt into warm, not boiling, soup so it stays creamy and does not curdle.
• Add lemon juice at the end and taste as you go so the soup tastes bright but not sour.
• Chop the dill finely so it spreads evenly and does not clump in the bowl.
• Use an immersion blender if you want fewer dishes and easier cleanup.
• Chill the soup for at least 2 hours if you plan to serve it cold so the flavors settle and mellow.

How to Make Zucchini Soup with Yogurt Lemon and Dill

Step 1: Prep the vegetables

Wash the zucchini and trim the ends. Slice them into half-moons about ¼ inch thick so they cook quickly. Dice the onion, mince the garlic, and peel and dice the potato.

Chop the dill and parsley and set them aside. Zest the lemon first, then juice it into a small bowl so you can add it gradually later.

Step 2: Sauté the aromatics

Heat the olive oil and butter in a large pot over medium heat. Add the diced onion with a pinch of salt and cook 4 to 5 minutes, stirring often, until the onion turns soft and translucent. Add the garlic and cook 30 seconds to 1 minute, just until it smells fragrant.

Add the sliced zucchini and diced potato to the pot. Season with another pinch of salt and the black pepper, then stir to coat the vegetables in the oil and aromatics.

Step 3: Soften the zucchini

Cook the zucchini and potato mixture over medium heat for 6 to 8 minutes. Stir occasionally so the vegetables cook evenly and do not stick. The zucchini will release some liquid and start to look glossy and tender.

Taste a piece of zucchini. It should taste soft with a little bite left, not mushy. This step builds flavor before you add the broth.

Step 4: Add broth and simmer

Pour in the broth and stir well, scraping the bottom of the pot to lift any browned bits. Raise the heat to bring the soup to a gentle boil. Once it starts to bubble, lower the heat to a steady simmer.

Cover the pot partially and cook 10 to 15 minutes. The potato should turn very tender and the zucchini should feel soft enough to crush with a spoon.

Step 5: Blend the soup

Turn off the heat and let the soup cool for 5 to 10 minutes. If you use an immersion blender, blend the soup in the pot until it turns very smooth and creamy. Move the blender around the pot so you catch every chunk.

If you use a countertop blender, work in batches. Fill the blender no more than halfway, vent the lid slightly, cover with a kitchen towel, and blend until smooth. Return the blended soup to the pot.

Step 6: Add yogurt, lemon, and dill

In a small bowl, whisk the Greek yogurt with a ladle of warm soup. This step warms the yogurt gently and keeps the texture smooth. Pour the yogurt mixture back into the pot and stir until the soup looks creamy and uniform.

Stir in the lemon zest, 2 tablespoons of lemon juice, chopped dill, and parsley if you use it. Taste and adjust with more salt, pepper, or lemon juice until the flavor tastes bright and balanced.

Step 7: Adjust thickness and reheat gently

Check the thickness of the soup. If it feels too thick, add a splash of broth or water and stir until you like the texture. If it feels too thin, let it simmer on low heat for a few minutes to reduce slightly.

Keep the heat low so the soup stays hot but does not boil. High heat can cause the yogurt to separate and lose its silky texture.

Step 8: Serve and garnish

Ladle the Zucchini Soup with Yogurt Lemon and Dill into bowls. Add a small spoonful or swirl of yogurt on top if you like. Drizzle a little olive oil, then finish with extra dill, parsley, or a pinch of red pepper flakes.

Serve the soup warm with crusty bread, pita, or a simple side salad. If you want a chilled version, cool the soup completely, chill it in the fridge, then garnish right before serving.

What to Serve with Zucchini Soup with Yogurt Lemon and Dill

Serve this soup with warm crusty bread, garlic toast, or pita for dipping into the creamy broth. A simple green salad with cucumber, tomato, and a lemony dressing pairs nicely with the dill and yogurt flavors. You can add grilled chicken, roasted chickpeas, or a quinoa salad on the side if you want more protein.

Offer sliced fresh fruit or a light yogurt parfait for dessert to keep the meal fresh and balanced. A tall glass of sparkling water with lemon or cucumber rounds out the meal and echoes the bright flavors in the soup.

Storage Options

• Store leftover Zucchini Soup with Yogurt Lemon and Dill in an airtight container in the fridge for up to 3 to 4 days.

• Freeze the soup without the yogurt for best texture, up to 2 months, then thaw in the fridge and stir in fresh yogurt and dill after reheating.
• Reheat gently on the stove over low to medium-low heat, stirring often, and avoid boiling so the yogurt stays creamy.
• Add a splash of broth or water while reheating if the soup thickens in the fridge, then taste and adjust lemon and salt before serving.
