Ingredients
- •2 tablespoons olive oil
- •1 medium onion, finely chopped
- •2 garlic cloves, minced
- •4 cups fresh spinach leaves, washed
- •2 cups broccoli florets
- •4 cups vegetable stock
- •1 medium potato, peeled and diced
- •1/2 cup heavy cream
- •Salt to taste
- •Black pepper to taste
- •4 slices of day-old bread, cut into cubes
- •1 tablespoon lemon zest
- •1 teaspoon fresh thyme leaves
- •1 tablespoon melted butter
Instructions
- 1
Heat the olive oil in a large pot over medium heat. Add the chopped onion and sauté for 3-4 minutes, until softened and translucent.
- 2
Add the minced garlic and cook for an additional minute, stirring frequently to prevent burning.
- 3
Stir in the fresh spinach leaves, broccoli florets, and diced potato. Cook for 2-3 minutes until the vegetables begin to soften slightly.
- 4
Pour in the vegetable stock and bring the mixture to a boil. Reduce the heat to low, cover the pot, and let it simmer for 15-20 minutes, or until the broccoli and potato are tender.
- 5
While the soup is simmering, prepare the croutons. Preheat your oven to 375°F (190°C). In a mixing bowl, toss the bread cubes with melted butter, lemon zest, and fresh thyme leaves. Spread the cubes evenly on a baking sheet and bake for 8-10 minutes, or until golden brown and crispy.
- 6
Once the vegetables in the soup are fully cooked, use an immersion blender to puree the mixture until smooth. For an extra-velvety texture, strain the soup through a fine-mesh sieve if desired.
- 7
Stir in the heavy cream and season with salt and black pepper to taste. Heat gently for 2-3 minutes to combine the flavors.
- 8
Serve the soup hot, topped with the lemon thyme croutons, and enjoy.

Frequently Asked Questions
Q: Can I use frozen spinach and broccoli instead of fresh?
A: Yes, you can use frozen spinach and broccoli if fresh is not available. Thaw and drain the spinach before adding it to the pot to avoid excess water in the soup. For frozen broccoli, you can add it directly to the pot without thawing, but adjust the cooking time as it may cook faster than fresh.
Q: Can I substitute the heavy cream with a non-dairy alternative?
A: Absolutely! You can replace heavy cream with non-dairy options like coconut cream, cashew cream, or unsweetened almond milk. Keep in mind that coconut cream may slightly alter the flavor, adding a hint of coconut to the soup.
Q: What can I use instead of potato to thicken the soup?
A: If you prefer not to use potato, you can substitute it with an equal amount of cauliflower florets or a medium-sized peeled parsnip. Both will add creaminess without affecting the flavor significantly.
Q: How do I store leftover soup, and how long will it keep?
A: Store leftover soup in an airtight container in the refrigerator for up to 3 days. To reheat, warm it gently on the stovetop over low heat, stirring occasionally. Avoid boiling the soup again, especially if it contains cream, to prevent curdling.
Q: Why is my soup not as smooth as I expected?
A: If your soup isn’t smooth, it may be due to inadequate blending. Use an immersion blender and blend thoroughly, or transfer the soup to a countertop blender in batches. For an ultra-smooth texture, strain the soup through a fine-mesh sieve after blending.
Q: Can I make the croutons in advance?
A: Yes, the croutons can be prepared up to 2 days in advance. Once baked and cooled, store them in an airtight container at room temperature. If they lose their crispness, reheat them in the oven at 350°F (175°C) for a few minutes before serving.
Q: What are some variations or additional toppings for this soup?
A: You can add toppings like a drizzle of olive oil, a dollop of sour cream, or freshly grated Parmesan cheese for extra flavor. For a heartier version, stir in cooked rice, quinoa, or shredded chicken before serving. Fresh herbs like parsley or chives also make great garnishes.
