Creamy Summer Squash Soup is my favorite answer to a sun-soaked day when you crave something comforting but not too heavy. Brimming with fresh flavors from seasonal squash and a touch of brightness from lemon, this soup is as easy on the eyes as it is on the palate. Each spoonful reminds me of relaxed evenings sitting on the porch, often wishing I had made a double batch because everyone always asks for seconds.
I first whipped up this soup in an effort to use up garden squash and never looked back. Now, it is my go-to for bringing a bit of sunshine to the table anytime.
Ingredients
- Summer squash: Choose squash that feels firm with smooth unblemished skins for the sweetest flavor. Cutting into half-moons helps them cook evenly.
- Onion: Fresh yellow or white onions are best. They add sweetness and flavor as the base of the soup.
- Potato: This gives body and creamy texture without needing cream. Look for waxy potatoes if you like a silkier finish.
- Garlic: Fresh cloves add an aromatic depth. Choose plump cloves free of blemishes.
- Fresh thyme: The little leaves add earthy brightness. Look for perky stems and strip leaves just before using.
- Coconut oil or Olive oil: Either gives a lovely depth to the sauté. Use extra virgin olive oil for added richness or coconut oil for a hint of sweetness.
- Vegetable stock: Go for low sodium and quality stock to let the squash’s flavor shine.
- Coconut milk: Full fat canned coconut milk is best for extra creaminess.
- Lemon juice: Freshly squeezed gives the soup a lift and keeps flavors balanced.
- Kosher salt and pepper: Season to taste and bring all flavors together smoothly.
Instructions
- Prepare the Vegetables:
- Dice onion and potato for even cooking. Cut summer squash into half-moons. Mince garlic and remove thyme leaves from stems.
- Sauté the Aromatics:
- Add coconut or olive oil to a large pot over medium heat. Add onions, squash, potato, garlic, and thyme leaves. Stir and cook for about five minutes until onions begin to soften but do not brown. This coaxes out their flavor gently.
- Simmer:
- Pour in the vegetable stock. Raise the heat to bring to a gentle boil. Once it bubbles, lower the heat and let it simmer uncovered. Stir occasionally and cook for fifteen to twenty minutes until all vegetables are fork-tender. This step melds the flavors and softens the squash and potato perfectly.
- Purée until Smooth:
- Let the pot cool for several minutes for safety. Working in batches if needed, carefully pour the soup into a blender. Puree until you achieve a silky smooth texture. Always hold the blender lid down with a kitchen towel when working with hot liquids to prevent accidents.
- Finish with Creaminess:
- Return the soup to the pot over medium low heat. Pour in coconut milk and lemon juice. Stir gently until fully blended. Taste and add salt and pepper as needed. This is when the soup transforms from simple to luxurious.
- Top and Serve:
- Ladle the soup into bowls. Garnish with a swirl of coconut milk and a scattering of fresh thyme leaves for fresh flavor and beauty. Serve warm and savor.

Lately I am never without a can of coconut milk in my pantry because it makes this soup irresistibly rich. My grandmother loved anything lemony and would always sneak an extra squeeze into her bowl. That fresh citrus finish makes every bite sing.
Storage Tips
Store cooled soup in a sealed container in the fridge up to four days. For longer storage, freeze in individual portions so you can reheat without defrosting the entire batch. Gently reheat on the stove with a splash of extra stock if needed to restore creamy texture.
Ingredient Substitutions
If you are out of coconut milk, try oat milk or even a splash of cashew cream for a different twist. Yukon Gold potatoes add silkiness, but you can swap in sweet potato if you want a slightly sweeter soup. Fresh dill or basil work in place of thyme for a different herbal note.
Serving Suggestions
I love pouring this soup into a shallow bowl and topping with microgreens or toasted pumpkin seeds for crunch. Crusty sourdough bread makes for a satisfying accompaniment, or serve alongside a bright salad of summer greens for an elegant lunch.
Cultural and Seasonal Context
This recipe is a celebration of summer’s bounty. Squash has a long heritage as a star vegetable in global kitchens from Italy to the American South. Making squash soup in early summer is a tradition in my family that signals the start of warm weather meals.
Seasonal Adaptations
Swap in zucchini if yellow squash is not available locally. Add a handful of fresh peas for a vibrant pop of green and sweetness. Garnish with torn basil if thyme is not in season.
Success Stories
Once I made a triple batch for a family reunion lunch and every bowl came back completely empty. This is the soup friends most often request when summer squash arrives at farmers’ markets. It has also converted a few folks who claimed not to like squash at all.

With a basket of ripe summer squash and a handful of pantry basics you can treat yourself to a creamy comforting soup that truly feels like summer in a bowl. This recipe never fails to bring compliments and happy silence at the table especially when I serve it with an extra drizzle of coconut milk.
