Start to Finish: 1 hour, 10 minutes

Servings: 8


  • 4 large shallots (about 3 oz. each), finely chopped (about 1 3/4 cups)

  • 4 cloves garlic, finely chopped

  • 8 tbsp. butter, melted

  • 2 1/2 cups heavy cream

  • 6 sprigs fresh rosemary (each 3 inches long)

  • 4 tbsp. canola oil

  • 2 1/2 lb. medium Brussels sprouts, trimmed and halved (about 9 cups)

  • 1 1/2 cups of rustic white bread cut into 1/2-inch cubes (about 6 oz.)

  • 1 1/2 tsp. dried sage

  • 1 1/2 tsp. dried poultry seasoning

  • 1 1/4 tsp. celery salt (optional)


1. In a medium saucepan, cook the shallots and garlic in 4 tbsp. butter over medium heat, stirring often, until tender, about 5 minutes. Add the cream and rosemary. Bring to a boil over high heat. Cook over medium until the liquid is reduced to 21/4 cups, about 15 minutes. Discard the rosemary sprigs. Season with salt and pepper.

2. In a large cast-iron skillet, heat 2 tbsp. oil over medium-high. Add half the Brussels sprouts, cut-side down; season. Cook until browned, about 3 minutes. Transfer to a large bowl. Repeat with the remaining 2 tbsp. oil and the remaining Brussels sprouts. Return all the Brussels sprouts to the skillet. Add about 1/4 cup water. Cover and cook over medium-high heat until almost tender, 3 to 4 minutes. Stir in the shallot mixture; season. Transfer to a 9-by-13-inch glass baking dish and arrange the Brussels sprouts in an even layer, cut-side up.

3. For the stuffing croutons, in a food processor, pulse the bread cubes until coarse crumbs form. In a medium bowl, toss the breadcrumbs with the remaining 4 tbsp. melted butter, the sage, poultry seasoning, and celery salt (if using); season generously.

4. Preheat the broiler. Sprinkle the stuffing croutons on top of the Brussels sprouts. Broil the Brussels sprouts until the croutons are golden brown and toasted, about 5 minutes.
