500 ml vegetable stock: The flavorful liquid that ties everything together while keeping it plant-based.

How to Make Super Healthy Watercress and Spinach Soup Recipe

Step 1: Sauté the Base Vegetables

Start by heating the olive oil in a pan over medium heat. Add the diced onion and finely chopped celery, and let them soften gently for about 3 minutes. Then toss in your chopped sweet potato, allowing it to cook alongside for another 3 minutes. Finally, stir in the crushed garlic and let its fragrance bloom for 2 minutes more. This slow build creates a layered base that’s aromatic and inviting.

Step 2: Simmer with Vegetable Stock

Pour in the vegetable stock and bring everything to a boil. Once boiling, reduce the heat, cover the pan, and let the mixture simmer for 20 minutes. This slow simmer lets the sweet potato tenderize fully and the flavors meld, forming a tender, flavorful foundation.

Step 3: Add the Greens

Now for the star ingredients: toss in the fresh watercress and spinach leaves. Let them cook just for 4 minutes so they wilt nicely but keep their vibrant color and vitality. This step ensures the soup retains its bright, fresh vegetable flavor without becoming dull.

Step 4: Blitz to Creamy Perfection

Remove the pan from heat and grab your handheld blender. Blend the soup until it reaches a smooth, luscious consistency. This transforms the soup into a velvety green dream that’s easy to enjoy and perfect for warming you up.

Step 5: Toast the Seeds

While the soup cools just a little, toast your mixed sunflower and pumpkin seeds in a dry pan for about 1 minute. As they start to pop and release a rich, nutty aroma, you’ll know they’re ready. This simple toasting step brings out the best crunch and flavor in your toppings.

Step 6: Finish and Serve

Ladle the soup into beautiful bowls, add a swirl of extra virgin olive oil for richness, and sprinkle over the toasted seeds. This final flourish adds texture and makes each serving feel truly special.

Garnishes

To elevate your soup, try adorning it with a handful of freshly cracked black pepper or a few delicate microgreens alongside the toasted seeds. A light sprinkle of grated Parmesan or a dollop of Greek yogurt can soften the edges beautifully and add a creamy tang.

Side Dishes

This soup pairs wonderfully with crusty wholegrain bread or a slice of garlic toast for dunking. Serve it alongside a fresh, vibrant salad or roasted vegetables to make it a more substantial meal without overwhelming its delicate flavors.

Creative Ways to Present

For a stunning presentation, serve the soup in clear glass bowls to showcase its vibrant green color. Swirling a drizzle of herb-infused oil or a touch of crème fraîche in spirals on top can also add visual appeal. If you want to impress guests, try serving it in petite cups as a sophisticated starter.

Make Ahead and Storage

Storing Leftovers

This soup stores beautifully in an airtight container in the fridge for up to 3 days. The flavors tend to deepen overnight, making leftovers even tastier. Just give it a gentle stir before reheating to reincorporate any settled solids.

Freezing

You can freeze this soup with ease. Portion it into freezer-safe containers, leaving a little space at the top for expansion. It stays fresh for up to 3 months, so you’ll always have a wholesome, ready-made meal on hand for busy days.

Reheating

Reheat the soup gently on the stove over low to medium heat, stirring frequently. Avoid boiling vigorously to keep the vibrant color and fresh taste intact. Add a splash of water or vegetable stock if it becomes too thick during reheating.

FAQs

Can I use frozen spinach and watercress for this soup?

Absolutely! Frozen spinach works well and can be added directly into the simmering soup. Watercress’s delicate texture means fresh is preferable, but you can substitute baby spinach or kale for a similar effect when fresh watercress isn’t available.

Is this soup suitable for a vegan diet?

Yes, this Super Healthy Watercress and Spinach Soup Recipe is completely vegan as long as you use vegetable stock and avoid any animal-derived garnishes. It’s a plant-powered delight through and through!

What can I substitute for sweet potato?

If you don’t have sweet potato on hand, butternut squash or pumpkin make great alternatives. They offer similar sweetness and creaminess that complement the greens perfectly.

How spicy is this soup?

This soup isn’t spicy by nature. The gentle garlic and peppery watercress add complexity without heat. You can always add a pinch of chili flakes or a dash of hot sauce to spice it up if desired.

Can I add protein to this soup?

Definitely! For a protein boost, stir in cooked lentils, chickpeas, or shredded chicken after blending. Topping with toasted nuts or seeds also adds healthy fats and protein for extra nourishment.
