Ingredients

Instructions

  1. Preheat oven to 375 degrees Fahrenheit. Bring the vegetable broth or water to boil in a heavy-bottomed pot. Add the quinoa, cover, reduce heat to low and simmer for 17 to 20 minutes, or until all of the liquid is absorbed. Cover and set aside.
  2. Toss the prepared Brussels sprouts with enough olive oil to lightly coat the sprouts on all sides. Arrange in a single layer on a rimmed baking sheet and bake for about 12 to 18 minutes, until they’re starting to caramelize on the edges.
  3. Reduce the oven heat to 350 degrees. Stir the dried oregano, thyme, salt, pepper, nutmeg and red pepper flakes into the quinoa. Then stir in the cheese until it’s all melted. Stir in the milk until the cheese and milk are evenly incorporated into the quinoa. Discard any burnt single Brussels sprout leaves on the pan, then stir the roasted sprouts into the quinoa. Transfer the mixture to an 8 by 8-inch square baking dish and sprinkle evenly with grated Parmesan.
  4. Melt the butter in a medium-sized pan over medium heat. Add the garlic and cook just until fragrant, stirring often. Add the bread crumbs and cook for 2 to 3 minutes, until slightly browned and crisp. Sprinkle the bread crumbs over the gratin.
  5. Bake uncovered for 25 minutes, until the top is golden. Allow to cool for 10 minutes before serving.

Notes

Recipe adapted from The High-Protein Vegetarian Cookbook by Katie Parker.
Serving suggestions: I think this creamy dish would go great with a green salad, like my favorite green salad with apple or a little green arugula salad.
Storage suggestions: This dish keeps well in the refrigerator, covered, for several days.
Change it up: I think this gratin would be great with roasted cauliflower! Feel free to play with the vegetables and spices.
Prepare in advance: I’m pretty sure you could assemble this gratin in advance. Just cover it and refrigerate it until you’re ready to bake. You’ll need to add about 10 to 15 minutes baking time since the gratin will be chilled when you put it in the oven.
