Ingredients

• 1/4 cup unsalted butter (or olive oil for dairy-free)

• 1 1/2 cups diced yellow onion (about 1 medium onion)

• 4 teaspoons minced fresh garlic (about 4 cloves)

• 1 teaspoon salt

• 1/4 teaspoon freshly ground black pepper

• 1 teaspoon dried thyme

• 1 teaspoon dried parsley

• 6 cups chicken or vegetable broth

• 1 tablespoon fresh lemon juice

• 1 bay leaf

• 4 cups peeled and chopped potatoes (about 700g)

• 4 cups cauliflower florets (about 480g)

• optional: 1/2 cup heavy cream

• optional toppings: chopped chives, parsley, scallions, croutons, crumbled bacon

Directions

1. In a large stockpot or Dutch oven, melt butter over medium heat. Add the diced onions and sauté until translucent, about 5 minutes.

2. Stir in the garlic, salt, pepper, thyme, and parsley. Cook for 1 minute until fragrant.

3. Add the broth, lemon juice, bay leaf, potatoes, and cauliflower. Bring to a boil, then reduce to a simmer and cook for 35 minutes until the vegetables are tender.

4. Remove the bay leaf. Use an immersion blender to puree the soup until smooth and creamy. Alternatively, let the soup cool slightly and blend in batches using a regular blender.

5. If using, stir in the heavy cream for added richness.

6. Serve warm with your choice of toppings such as croutons, chopped herbs, or crispy bacon.
