Recipe Details


We’re leaning further into cozy fall flavors with this spin on a past hit cauliflower dish. Here, Chef Andrea highlights multicolor heirloom cauliflower, roasting it until beginning to crisp, then combining it with fresh spinach, pine nuts, and almonds. It’s all tossed in a bright, tangy vinaigrette blending sherry, capers, and a touch of honey. On the side, mashed butternut squash laced with Gruyère and brown butter provides an extra dose of comfort that gives mashed potatoes a run for their money.

Cooking Steps

  1. Prepare Ingredients

    Prepare Ingredients

    Preheat oven to 450°F. Rinse spinach and pat dry with paper towel. Rinse cauliflower and cut to ½-inch wide florets, if needed. Cut butternut squash cubes to 1-inch pieces, if needed. Roughly chop capers

  2. Season Vegetables

    Season Vegetables

    On a baking sheet, toss squash with 1 tablespoon olive oil, ¼ teaspoon salt, and pepper as desired. Arrange in a single layer on 1 half of baking sheet. On other half of baking sheet, toss cauliflower with 1 tablespoon olive oil, ¼ teaspoon salt, and pepper as desired and arrange in a single layer.

  3. Roast Vegetables

    Roast Vegetables

    Roast cauliflower and butternut squash until browned, 10-12 minutes. Then, remove baking sheet from oven and scatter pine nuts and almonds over cauliflower (not squash). Return to oven and roast until pine nuts are toasted, 2 minutes more. Remove from oven and set aside to cool.

  4. Make Caper Vinaigrette

    Make Caper Vinaigrette

    While vegetables roast, in a large bowl, combine sherry vinegar, ½ packet honey (use remainder to sweeten a cup of tea), and capers. Slowly whisk in 2 tablespoons olive oil and season with ⅛ teaspoon salt and pepper as desired. Set aside.

  5. Finish Squash

    Finish Squash

    Once vegetables have finished roasting, in a small pot, heat butter over medium heat, stirring occasionally, until golden and fragrant, 4-6 minutes. Remove from heat. Add roasted squash to pot with butter and, using a fork, mash until smooth and combined. Stir in Fontina, Gruyère, and heavy cream to combine. Taste and add salt and pepper as desired.
