If using fresh chestnuts, score them with an X, then cook them in boiling water until soft, about 20 minutes. Drain and peel the chestnuts.



Ingredient Checklist


Instructions Checklist
  • Bring a large pot of water to a boil; add salt. Add florets, and cook until just tender, about 6 minutes. Drain in a colander, and rinse under cold running water until cool. Let dry on paper towels.

  • Preheat oven to 400 degrees. Finely chop stems to make 1 1/2 cups. Melt butter in a large skillet over medium heat; add stems, shallots, and garlic. Season with salt and pepper. Cook, stirring occasionally, until pale golden brown, about 4 minutes. Add wine, stock, and cream. Simmer, stirring occasionally, until liquid has reduced by about half, 10 to 12 minutes. Let cool slightly. Stir in horseradish, and season with salt, pepper, and nutmeg. Puree mixture in a blender until smooth. Stir in thyme.

  • Spread florets and chestnuts in a 9-by-12-inch oval gratin dish. Season with salt and pepper. Pour puree on top, and gently stir to combine slightly. Sprinkle with cheese. Bake until bubbling and just golden brown, 30 to 35 minutes.

Loved this. I eliminated a few steps that made it quicker. I did not pre-boil the cauliflower, nor did I separately cook the stems. I cut the cauliflower into florets with stems attached. Sautéed the other ingredients (shallots, wine, etc), and did not puree anything. I simply poured the other ingredients over the cut cauliflower and baked. I did not use garlic- just not a flavor I thought would work well with cauliflower and shallots are a tiny bit garlicky anyway. I used a bit less horseradish

This is a show-stopper sidedish. There are quite a few steps for a vegetable dish, but if you want a vegetable to take along to a covered-dish party this is a great one.

This was tasty, but a lot of steps for a side dish.

Unfortunately, more liquid cooked out of the cauliflower, which was a surprise. We did not enjoy this as much as other veggie recipes. It sounded good...
