1 cup diced celery

How to Make Summer Soup Slow Cooker

Prep the veggies: Dice all the vegetables into bite‑sized pieces. The uniform size ensures even cooking.
Layer in the slow cooker: Start with the onion, garlic, and carrot at the bottom. Add the celery, zucchini, bell peppers, cucumber, and tomato on top. Sprinkle the cumin, smoked paprika, salt, and pepper over the vegetables.
Add liquids: Pour in the vegetable broth and coconut milk. Stir gently to combine.
Cook: Cover and cook on low for 6–7 hours or on high for 3–4 hours. The slow cooker will gently soften the veggies while infusing the spices.
Finish the soup: Once the vegetables are tender, stir in the lemon juice, dill, mint, and coconut cream swirl if using. Taste and adjust seasoning if needed.
Serve: Ladle the soup into bowls. Garnish with extra dill, cilantro, or a drizzle of coconut cream for a touch of elegance.

Tips for Best Results

Use fresh herbs: Fresh dill and mint bring a bright, clean flavor that’s essential for a summer soup.
Don’t overcook: The vegetables should retain a slight bite; this keeps the soup light and refreshing.
Adjust thickness: If you prefer a thicker soup, blend half the mixture with an immersion blender before adding the remaining half.
Cool it down: For an even cooler experience, chill the soup for an hour before serving.
Serve with crusty bread: A slice of warm baguette or a grilled pita makes a perfect accompaniment.

Variations

Protein boost: Add shredded rotisserie chicken or chickpeas for a more filling meal.
Spicy kick: Stir in a pinch of cayenne pepper or a diced jalapeño.
Herb swap: Replace dill with basil or parsley for a different aromatic profile.
Seasonal twist: Swap zucchini for summer squash or add corn kernels for a sweet crunch.

Storage

Cool the soup to room temperature, then transfer to airtight containers. Store in the refrigerator for up to 4 days. For longer storage, freeze in freezer‑safe bags or containers for up to 3 months. Reheat gently on the stovetop or in the microwave, adding a splash of water if it’s too thick.
