Description

This cauliflower gratin with caramelized leeks and pecans is a creamy, savory side dish made with Gruyère, Parmesan, heavy cream, and a touch of nutmeg. The tender cauliflower is baked until golden, then topped with sweet, balsamic-glazed leeks, while ground pecans add richness and subtle texture. Naturally gluten-free and low-carb, it’s an elegant yet comforting side dish for the holidays or any special meal.

Ingredients

  • 1 large head cauliflower, washed, patted dry, and cut into large florets
  • 2/3 to 1 cup (160–240 milliliters) organic heavy cream
  • 3 ounces (85 grams) Gruyère cheese, grated
  • 1/2 cup (approx 55 grams) ground pecans, preferably dry-roasted
  • A pinch of ground nutmeg
  • Salt and freshly ground black pepper, to taste
  • A handful of grated Parmigiano Reggiano, for topping
  • 2 large leeks
  • Avocado oil or extra virgin olive oil
  • 2 teaspoons good-quality balsamic vinegar

Instructions

  1. Preheat the oven to 375°F (190°C).
  2. Bring a pot of water to a boil. Add the cauliflower and cook for 5 to 7 minutes, depending on the size of the florets. The cauliflower should remain firm, as it will continue cooking in the oven.
  3. Drain the cauliflower thoroughly and arrange it in a 9-by-9-inch (23-by-23-centimeter) baking dish or another baking dish of a similar capacity.
  4. Combine the heavy cream, Gruyère, ground pecans, nutmeg, salt, and pepper. Pour the mixture evenly over the cauliflower, then sprinkle the Parmigiano Reggiano on top.
  5. Bake for 25 to 30 minutes, or until the cauliflower is tender and the top begins to turn golden.
  6. While the gratin is baking, prepare the leeks. Cut them in half lengthwise and clean them thoroughly, making sure there is no soil trapped between the layers. Pat dry and thinly slice the white and light green portions.
  7. Heat a small amount of avocado or olive oil in a large sauté pan over low to medium heat. Add the leeks and cook slowly, stirring whenever they begin to stick.
  8. When browned spots form on the bottom of the pan, add about 1 teaspoon of water and stir to release them. Continue cooking, stirring frequently and adding water 1 teaspoon at a time as needed, until the leeks are soft and caramelized, about 25 minutes.
  9. Add the balsamic vinegar, stir well, and remove the pan from the heat.
  10. Spoon the caramelized leeks over the cauliflower gratin. Return the dish to the oven and bake for 5 more minutes. Serve warm.

Notes

For the best flavor, lightly dry-roast the pecans before grinding them.

The flourless sauce will be creamy but relatively loose. For a thicker sauce, dissolve 2 teaspoons of arrowroot or tapioca starch in a small amount of cold water and mix it into the cream mixture.

Use only the white and tender light green portions of the leeks. The dark green leaves can be reserved for making stock.

An aged, slightly thick balsamic vinegar works especially well with the caramelized leeks.
