Step 1

Heat a large stockpot or Dutch oven over medium heat. Add bacon and cook until brown and crispy, about 6-8 minutes. Transfer to a paper towel-lined plate, reserving 1 tablespoon excess fat in the stockpot.

Step 2

Melt butter in the stockpot. Add garlic, onion and celery. Cook, stirring occasionally, until tender, about 3-4 minutes.

Step 3

Stir in cauliflower and bay leaf. Cook, stirring occasionally, until barely crisp-tender, about 4-5 minutes.

Step 4

Whisk in flour until lightly browned, about 1 minute.

Step 5

Stir in chicken broth and milk, and cook, stirring frequently, until slightly thickened, about 3-4 minutes.

Step 6

Bring to a boil; reduce heat and simmer until cauliflower are tender, about 12-15 minutes; season with salt and pepper, to taste.

Step 7

Puree with an immersion blender until desired consistency is reached.

Step 8

Serve immediately, garnished with bacon and parsley, if desired.
