• Salt and pepper to taste
• ½ cup grated parmesan cheese (omit for vegan)

Equipment Needed

• Medium pot
• Food processor
• Shallow bowls for serving

Instructions

1. Begin by gently heating the milk in a medium pot over medium heat. It’s crucial not to let it scorch, so keep a close eye on it. You want it to be warm and steamy, but not boiling.

2. While the milk is heating, prepare the tomato base. In a food processor, combine the drained diced tomatoes, tomato paste, chopped onion, salt, pepper, sugar, flour, butter (cut into pieces for easier blending), and coarsely chopped celery. Process this mixture until it’s completely smooth. This step is essential for achieving a velvety texture in the final soup.

3. Once the tomato mixture is smooth, carefully pour it into the pot with the warmed milk. Increase the heat to bring the soup to a boil, stirring constantly to prevent sticking or scorching.

4. Once the soup has reached a boil, immediately reduce the heat to a low simmer. Simmer for 15 minutes, stirring occasionally to ensure everything is cooking evenly and the flavors are melding together beautifully.

5. While the soup is simmering, it’s time to make the pesto. If you’re using store-bought pesto, you can skip this step.

6. For the Watercress and Hazelnut Pesto: In the food processor, add half of the basil or cilantro. Then add hazelnuts, 1/2 of the olive oil and garlic cloves. Add nutmeg, salt and pepper to the processor bowl, set lid in place and pulse grind the mixture into a thick paste.

7. Now, add any remaining basil or cilantro to the processor and grind into the paste by pulsing the processor again.

8. Transfer the pesto paste to a bowl and stir in the remaining olive oil and the grated parmesan cheese. This is where you can really customize the pesto to your liking.

9. Taste the pesto and adjust the seasonings (salt, pepper, nutmeg) as needed. Remember that pesto is meant to be bold and flavorful, so don’t be afraid to experiment.

10. Once the soup is ready, pour it into shallow bowls. Add a couple of rounded spoonfuls of pesto to each bowl and gently stir it into the soup. The pesto will create beautiful swirls of green and add a burst of fresh, herbaceous flavor to every spoonful.

Expert Tips & Tricks

• Roasting the tomatoes beforehand can intensify their flavor, adding a deeper, richer dimension to the soup. Roast them at 400°F (200°C) for about 20-25 minutes before blending.
• For a smoother texture, use an immersion blender directly in the pot after simmering. Be careful to avoid splattering.
• If you want to make the soup ahead of time, prepare it up to the simmering stage. Store it in the refrigerator for up to 2 days, and then reheat it gently before serving. Add the pesto just before serving.
• If the soup becomes too thick, add a little more milk or vegetable broth to thin it out to your desired consistency.
• Substitute heavy cream for part of the milk for an even richer, more decadent soup.
• Adjust the pesto to your liking. If you prefer a more garlicky pesto, add an extra clove of garlic. If you want a nuttier flavor, use toasted nuts.

Serving & Storage Suggestions

This Creamy Tomato Soup with Pesto is best served hot, immediately after preparation. Garnish with a sprig of fresh basil or a drizzle of olive oil for an elegant presentation. It pairs perfectly with grilled cheese sandwiches, crusty bread for dipping, or a simple green salad.

• Storage: Leftover soup can be stored in an airtight container in the refrigerator for up to 3 days.
• Freezing: For longer storage, freeze the soup in individual portions for up to 2 months. Do not add the pesto before freezing, as it will lose its vibrant color and flavor. Add the pesto when you reheat the soup.
• Reheating: Reheat the soup gently in a saucepan over medium heat, stirring occasionally, until heated through. Avoid boiling.
