I make a big pot of soup every weekend during the cooler months, it’s my version of “meal prep”. It doesn’t take much time, and it means that we always have something delicious and easy in the fridge–bonus, it’s always packed with veggies!

Why this recipe works

This recipe takes the classic combination of broccoli and cauliflower to the next level, resulting in a soup that’s both bright and savory. Grated sharp cheddar is melted in giving this a classic broccoli-cheddar flavor that is so well loved.

To enhance the color and add another vegetable, fresh spinach is blended in, adding a pop of brightness.

Ingredients you’ll need:

• For the vegetables this recipe uses cauliflower, broccoli and spinach. The spinach is blended in seamlessly and doesn’t overpower the cauliflower broccoli flavor in the soup.
• The soup’s base is built by sautéing onions and garlic in olive oil. This adds a richness to the broth.
• A pinch of red pepper flakes is added for a spicy kick that balances the overall taste, if you like something spicier, you can always add more.
• I always add a bay leaf to a soup because it adds a layer of depth and complexity.
• For the liquid, I like to use water in vegetable-based soups so that the broth doesn’t overpower the flavor, but you could also use vegetable or chicken broth.
• To finish, a touch of lemon juice adds brightness while grated sharp cheddar infuses the soup with rich and savory notes. If you don’t have lemon juice, lime juice would also work.

Expert tips

1. For a richer, greener soup, I use broccoli crowns or florets rather than the broccoli stem. They hold more flavor and keep the color vibrant.
2. To give the soup a spicy kick, you can add more chili flakes or sauté some chopped jalapeño with the onions and garlic.
3. The cauliflower and cheese lend a creamy texture to the soup. However, for an even creamier version, you can add a splash of heavy cream.

Step by step instructions

1. Heat olive oil over medium heat in a large Dutch oven or heavy-bottomed pot. Add onion and saute for 5 minutes until golden brown. Add garlic and chili flakes, cook for another minute until very fragrant.
2. Add broccoli and cauliflower, followed by salt. Stir to combine. Cover with water, add bay leaf. Bring to a boil. Cover and reduce heat to low, simmer for 15 minutes until vegetables are fork tender.

1. Remove bay leaf and add spinach, cook for a minute until spinach is just wilted.
2. Puree in a blender or with an immersion blender. Stir in cheese and lemon juice.
