Cheesy Mashed Cauliflower Gratin

Faith Gorsky

Which side dishes come to mind when you think of Thanksgiving dinner at your house? At my house, it’s fresh bread or rolls, candied sweet potatoes with brown sugar, the ubiquitous green bean casserole (or a fresh new twist on this classic casserole), squash of some kind (usually pureed at my house), vegetable gratin (mmm, like this delicious kale gratin), and some version of mashed potatoes.

While these side dishes are delicious, a lot of times, they sneak in wheat or another grain – like a creamy casserole with a white sauce thickened with flour, or veggie gratin with a breadcrumb topping. Since many people these days are finding out that they are gluten-intolerant (and many people are choosing to eat grain-free), I like to have a few grain-free/gluten-free options available.

This lovely dish is grain and gluten-free, but definitely not lacking in flavor. Onion, garlic, thyme, and cheese take care of that. It’s super smooth and velvety, like the smoothest mashed potatoes you’ll ever eat, times ten. If you prefer your mashed veggies with a bit of texture, just skip the pureeing step and mash the cauliflower by hand with a potato masher, which makes this dish come together even faster and saves you the work of cleaning the blender or food processor. Either way, this dish is sure to be a hit.

Cheesy Mashed Cauliflower Gratin is the perfect gluten free and grain free side dish.

This dish is very rich and with all the other sides present at Thanksgiving dinner, this recipe should serve four to six people. However, if you want to serve it as part of a regular meal where there aren’t ten other side dishes to sample, it will serve about four.

It’s a lovely new item to add to your holiday meal repertoire.

Ingredients

  • 1 lb cauliflower florets
  • 2 tablespoons butter plus more to grease the dish
  • 1 medium onion diced
  • 2 large cloves garlic minced
  • 1/2 teaspoon dried thyme
  • 4 oz reduced-fat cream cheese at room temperature
  • 2 tablespoons heavy cream if necessary
  • 1/2 teaspoon salt
  • 1/8 teaspoon black pepper
  • 80 g Emmental cheese or any Swiss cheese you like, shredded (about 2/3 cup)
  • 2 teaspoons minced fresh parsley

Instructions

  1. Preheat the oven to 400F; grease a 1.5-liter gratin dish with butter (or you can use smaller ramekins for individual servings).
  2. Boil or steam the cauliflower until very tender (about 20 minutes boiling or 15 minutes steaming). Drain very well.
  3. Add the butter to a medium skillet over medium heat; add the onion and cook until softened, but not browned, about 5 to 7 minutes, stirring occasionally. Add the garlic and thyme and cook 2 minutes more, stirring constantly. Turn off heat.
  4. Transfer the drained cauliflower and cream cheese to a food processor or blender and process until smooth. (I used a blender and found that I needed to add 2 tablespoons of liquid for the blades to run properly; I chose cream so it wouldn’t thin out the cauliflower too much.) Add the cream as needed.
  5. Transfer the pureed cauliflower, onion, salt, black pepper, and half the shredded cheese to a large bowl and stir to combine.
  6. Spread the cauliflower mixture in the prepared dish, and sprinkle the remaining cheese and the parsley on top. Bake until warm throughout and the cheese is melted, about 15 to 20 minutes. (If you want, you can run the gratin under the broiler for a couple minutes to brown, but stay with it!)
  7. Serve hot.

Recipe Notes

If you prefer your mashed veggies with a bit of texture, just skip the pureeing step and mash the cauliflower by hand with a potato masher, which makes this dish come together even faster and saves you the work of cleaning the blender or food processor. Either way, this dish is sure to be a hit.
