Wholesome Ingredients for This Watercress Soup with Peas

We’ve deliberately chosen ingredients that not only deliver maximum flavor but also pack a major nutritional punch. Let’s take a closer look at a few:

• Watercress: A nutrient-dense leafy green loaded with antioxidants, vitamin K, and calcium. When shopping, look for vibrant, firm leaves without yellowing.
• Frozen peas: Sweet and slightly starchy, they add both flavor and a creamy texture when blended. Bonus: frozen peas are just as nutrient-packed as fresh ones.
• Fresh mint: Adds a fragrant, refreshing finish and pairs beautifully with the sweetness of the peas. Fresh is best, but you can substitute parsley for a milder herb.
• Greek yogurt: A protein-rich alternative to cream. Choose plain, unsweetened yogurt for the best results—or swap it for coconut yogurt to keep it dairy-free.

How to Make Watercress Soup with Peas

1. Prepare the croutons: Preheat your oven to 375°F. Tear the bread into bite-sized pieces, toss with olive oil, salt, and pepper, and spread on a baking sheet. Bake for 10 minutes until golden brown and crispy. Set aside to cool.
2. Prep the watercress: Remove thick stems, soak the leaves in cold water for 5 minutes, then rinse and spin dry. Roughly chop the leaves.
3. Sauté the leeks: Heat olive oil in a large pot over medium heat. Cook leeks with a pinch of salt and pepper for about 10 minutes, stirring occasionally, until softened and aromatic.
4. Add the stock and greens: Pour in the chicken stock and water, then bring to a boil. Reduce heat, stir in watercress and peas, and simmer for 5 minutes until peas are tender.
5. Prepare the yogurt sauce: Mix Greek yogurt with lemon juice and season with salt and pepper. Adjust the consistency with a splash of water if needed.
6. Blend the soup: Stir in the mint leaves and purée the soup in a blender until smooth. Adjust thickness with water if necessary. Reheat if serving warm or chill for a refreshing cold soup.
7. Serve: Ladle soup into bowls and garnish with croutons, a dollop of yogurt sauce, and fresh mint leaves.

How to Customize This Watercress Soup with Peas for Your Diet

• Gluten-free: Use gluten-free bread for the croutons or skip them altogether, replacing them with toasted nuts like almonds for crunch.

• Keto-friendly: Reduce the peas to half and increase the watercress proportion to keep it low-carb.
• Higher protein: Add a scoop of unflavored protein powder to the soup before blending or mix in shredded chicken.
