Ingredients You’ll Need

Vegetables

2 tablespoons olive oil (extra virgin for best flavor, but any neutral olive oil works)
1 medium yellow onion, diced
3 cloves garlic, minced (use jarred minced garlic if you want a shortcut)
3 medium zucchini, chopped into half moons
4 packed cups fresh baby spinach
1 small Yukon gold potato, peeled and diced (adds creaminess without heavy cream)

Liquids & Seasoning

4 cups low sodium vegetable broth
- Use chicken broth if you do not need the soup vegetarian.
- I like Better Than Bouillon vegetable base for strong flavor.
1 cup water, as needed to thin the soup
1 teaspoon kosher salt, more to taste
½ teaspoon freshly ground black pepper
½ teaspoon dried thyme or Italian seasoning
¼ teaspoon crushed red pepper flakes (optional, for a little heat)
Juice of ½ to 1 lemon, to taste
2 tablespoons fresh basil or parsley, chopped (optional but highly recommended)

Creamy Finish Options

Pick one of these to finish the soup:

¼ to ½ cup half and half
¼ cup heavy cream
½ cup canned coconut milk for a dairy free version
½ cup plain Greek yogurt or sour cream (stir in off heat so it does not curdle)

Garnishes

Extra chopped herbs (basil, parsley, or chives)
A drizzle of olive oil
Crushed red pepper flakes
Toasted pumpkin seeds or sunflower seeds
A spoonful of Greek yogurt or sour cream

Equipment List

Large soup pot or Dutch oven
Cutting board and sharp knife
Wooden spoon or spatula
Measuring cups and spoons
Blender
- Use an immersion blender for easy cleanup.
- A regular blender works too; blend in batches and vent the lid slightly.

Tips & Tricks

Slice zucchini into even pieces so they cook at the same rate.
Sauté onion and garlic until they smell sweet and turn translucent; that step builds flavor.
Add spinach at the end of cooking so it keeps a bright green color.
Use a small potato instead of extra cream if you want a lighter but still velvety texture.
Blend the soup very smooth for a silky feel or pulse it lightly if you like a bit of texture.
Taste and adjust salt and lemon juice at the end; that tweak often takes the soup from good to great.
Cool the soup slightly before blending so it does not splatter.
Stir yogurt or sour cream into warm, not boiling, soup so it stays smooth.
Keep leftovers a little thicker, then thin with broth or water when you reheat.
Double the batch and freeze in single portions for easy lunches.

How to Make Summer Spinach And Zucchini Soup Recipe

Step 1: Prep the Vegetables

Wash the zucchini and trim the ends, then slice them into half moons about ¼ inch thick. Dice the onion and peel and dice the potato into small cubes so it cooks quickly. Mince the garlic or use pre-minced garlic if you want to save a few minutes.

Step 2: Sauté the Aromatics

Heat the olive oil in a large pot over medium heat. Add the diced onion and a pinch of salt and cook 4 to 5 minutes until the onion turns soft and lightly golden around the edges. Stir in the garlic and cook about 30 seconds until it smells fragrant.

Step 3: Add Zucchini and Potato

Add the chopped zucchini and diced potato to the pot. Stir so the vegetables coat in the oil, onion, and garlic mixture. Cook 4 to 5 minutes, stirring occasionally, until the zucchini starts to soften and pick up a little color.

Step 4: Season and Add Broth

Sprinkle in the salt, pepper, dried thyme or Italian seasoning, and crushed red pepper flakes if you use them. Stir to coat the vegetables in the spices. Pour in the vegetable broth and enough water to just cover the vegetables, then bring the pot to a gentle boil.

Step 5: Simmer Until Tender

Lower the heat to a steady simmer. Cook 12 to 15 minutes until the potato cubes feel very tender when you poke them with a fork. Stir occasionally so nothing sticks to the bottom of the pot.

Step 6: Add Spinach and Fresh Herbs

Add the baby spinach to the hot soup. Stir until the leaves wilt completely, which takes 1 to 2 minutes. Toss in the fresh basil or parsley and stir again.

Step 7: Blend the Soup

Turn off the heat. Use an immersion blender directly in the pot and blend until the soup turns smooth and creamy. If you use a regular blender, work in batches, fill the jar no more than halfway, vent the lid slightly, and blend until smooth, then return the soup to the pot.

Step 8: Adjust Thickness and Add Creaminess

Check the thickness of the soup. Add a splash of water or broth if it feels too thick, or simmer a few minutes if it feels too thin. Stir in your choice of half and half, cream, coconut milk, or whisked yogurt or sour cream, then warm the soup gently over low heat.

Step 9: Brighten with Lemon and Final Seasoning

Squeeze in the lemon juice and stir. Taste and add more salt, pepper, or lemon if you want a brighter flavor. The soup should taste fresh, slightly tangy, and nicely seasoned.

Step 10: Serve

Ladle the Summer Spinach And Zucchini Soup into bowls. Swirl in a spoonful of yogurt or cream if you like and sprinkle on extra herbs or seeds. Add a tiny drizzle of olive oil on top for a pretty finish and extra richness.

What to Serve with it?

This Summer Spinach And Zucchini Soup Recipe pairs nicely with crusty bread, garlic toast, or a warm baguette for dipping. You can add a simple side salad with tomatoes, cucumbers, and a light vinaigrette to keep the meal fresh and crunchy. Grilled chicken, roasted chickpeas, or a slice of whole grain toast with avocado turns it into a more filling dinner. A cold glass of sparkling water with lemon or iced herbal tea keeps the meal light and refreshing.

Storage Options

Store leftover soup in an airtight container in the fridge for up to 4 days.
Let the soup cool to room temperature before you refrigerate or freeze it.
Freeze in freezer safe containers or silicone soup cubes for up to 3 months.
Reheat on the stove over low to medium heat and stir often until hot, then adjust thickness with a splash of water or broth.
Reheat in the microwave in short bursts, stirring between each, so the soup heats evenly and stays smooth.
