My free tip for this dish- warm the bowls with very hot (microwaved) water 5 minutes before serving, of course emptying the bowls before filling with soup. That will keep the soup toasty warm until the last spoonful.

Roasted Cauliflower Soup
4-5 servings as side dish
1 head cauliflower
6 slices bacon, diced
1 yellow onion, diced (about 1 C)
3 C chicken broth (homemade always preferred)
1 TB fresh thyme plus 1 ts
1 ts kosher salt
1/2 ts freshly cracked black pepper
1/4 ts freshly grated nutmeg
1/2 C heavy cream
2.5 C milk
1 C parmigiano reggiano plus 1/4 C
Fire up the oven to 400F. Roughly chop the cauliflower into pieces about 1-2" in size. Spread out on a sheet pan lined with foil and drizzle with a bit of EVOO, toss well, then season lightly with S&P. Roast for about 35-40 minutes, until lightly browned. Remove from the oven and set aside.
Put a large cast iron dutch oven on the stovetop over medium heat. Add a bit of EVOO, then get that bacon sizzling. Cook until crisp, stirring often, then remove with a slotted spoon. Cook the onion in the bacon fat until translucent, about 5-6 minutes. Add the cauliflower, broth, 1 TB thyme, nutmeg, and salt and pepper. Turn up the heat to medium high and bring just to a boil, then reduce heat and simmer for about 12 minutes, stirring occasionally.
Introduce your stick blender to the situation, or puree in batches in a blender. Next to the pot is the cream, milk, and 1 C of the cheese. Stir and adjust seasoning if needed with S&P. Return to low heat until warmed through, then serve in bowls with the reserved bacon, thyme, and cheese.
