Cauliflower and Broccoli Gratin with Spinach Sauce - Lower Carb, Gluten Free
Serves: 6 with no leftovers
  • 2 1/2 cups cauliflower florets, 1 small head of cauliflower 1-1 1/4 pounds
  • 2 1/2 cups broccoli florets, 1-1 1/4 pounds
  • 12 ounces baby spinach or 1 10 oz. package frozen spinach thawed
  • 6 tablespoons (3/4 stick) butter
  • 1/4 cup gluten free flour
  • 2/3 cup whole milk
  • 2/3-1 cup chicken broth
  • scant 1/4 teaspoon grated nutmeg
  • 1 cup freshly grated Parmesan cheese, divided (see instructions for how to divide)
  1. Steam cauliflower and broccoli until crisp-tender. Remove from steamer basket and set aside. Add fresh spinach to steamer basket and steam until just wilted. If using thawed frozen spinach, steam until heated. Remove basket with spinach in it and let drain and cool. Squeeze liquid out of spinach in batches with your hands and chop.
  2. Pour water out of steamer pot and dry. In the same pot, melt butter over medium heat. Add flour and whisk in. Cook, whisking often, for 3 minutes. Gradually whisk in milk and 2/3 cup of chicken broth and nutmeg. Add more chicken broth as necessary to create a sauce that is the consistency of turkey gravy. Pour liquid in slowly and whisk constantly and the sauce will be smooth and clump-free. Whisk over medium heat until sauce thickens, about 3 minutes. Remove from heat and stir in spinach and 2/3 cup cheese.
  3. Coarsely crumble cauliflower and broccoli with your fingers (into small bite-size pieces) and mix into sauce in pot. Season with salt and pepper to taste.
  4. Butter a 1 1/2 quart (about 8 "x 10" x 2" deep) baking dish. Spread mixture into prepared dish. (May be made 8 hours ahead of time up to this point and kept covered and refrigerated.)
  5. Preheat oven to 350°. Sprinkle remaining 1/3 cup Parmesan over the gratin. Bake until heated through, about 25 minutes. Add 10 minutes cooking time if just removing from the refrigerator. Turn oven to broil and cook until top is lightly brown, about a minute or two. Serve hot.
