Ingredients

1/4 cup (56g) unsalted butter

1 1/2 cups (195g) diced yellow onion (about 1 medium)

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 (1.4L) chicken or vegetable broth

1 tablespoon fresh lemon juice

1 bay leaf

4 cups (700g) peeled and chopped potatoes (about 1-inch pieces)

4 cups (480g) cauliflower florets

Optional: 1/2 cup (120ml) heavy cream

Optional for serving: chopped chives, scallions, or parsley; croutons; crumbled bacon

Instructions

  1. Melt butter in a large pot over medium heat. Add diced onions and cook until translucent, about 5 minutes.
  2. Stir in minced garlic, salt, pepper, thyme, and parsley. Cook for 1 minute.
  3. Add broth, lemon juice, bay leaf, potatoes, and cauliflower. Bring to a boil, then reduce heat and simmer for 35 minutes until vegetables are tender.
  4. Remove from heat and discard bay leaf. Use an immersion blender to puree until smooth, or blend in batches using a regular blender. Stir in heavy cream if using.
  5. Serve warm, topped with chives, croutons, and/or crumbled bacon as desired.

Notes

  • Soup can be frozen for up to 3 months. Thaw and reheat before serving.
  • Lemon juice adds brightness and enhances flavor—don’t skip it!
  • Frozen cauliflower can be substituted for fresh.
  • Yukon gold potatoes are ideal, but other white or russet potatoes also work.
  • For a dairy-free version, substitute butter with olive oil and skip cream.
