Description

Keto cauliflower au gratin elevates humble cauliflower into a luxurious side dish with rich cheese and creamy textures. Elegant French-inspired comfort beckons dieters to savor low-carb indulgence without sacrificing flavor or satisfaction.


Ingredients

Scale

Main Ingredients:

  • 1 head cauliflower (or 4 cups), cut into slices
  • 2 cups gruyere cheese, shredded (or Swiss cheese)
  • 1 ½ cups heavy cream

Seasoning and Garnish:

  • 4 green onions, sliced
  • Salt, to taste
  • Black pepper, to taste

Instructions

  1. Preheat the oven to a moderate temperature and prepare a baking dish with a light spray of cooking oil to prevent sticking.
  2. Create the first layer of cauliflower slices across the bottom of the dish, ensuring even coverage and maintaining a uniform thickness.
  3. Generously distribute half of the Gruyere cheese over the initial cauliflower layer, spreading it evenly to guarantee consistent flavor in each bite.
  4. Sprinkle finely chopped green onions across the cheese layer to introduce a subtle, sharp note to the casserole.
  5. Season the layer with salt and freshly ground black pepper, carefully distributing the seasoning to enhance the overall taste profile.
  6. Construct a second layer of cauliflower slices directly atop the first, creating a substantial and hearty base for the dish.
  7. Slowly drizzle heavy cream over the entire casserole, ensuring complete and uniform coverage of the vegetable layers.
  8. Complete the dish by topping with the remaining Gruyere cheese, creating a rich and golden surface that will develop a crisp, appetizing crust during baking.
  9. Shield the casserole with aluminum foil and place in the preheated oven for the initial cooking phase, which helps to tenderize the cauliflower.
  10. Remove the foil during the final stage of baking to allow the cheese to transform into a beautifully golden and bubbling crust.
  11. Once fully cooked, remove from the oven and allow the casserole to rest briefly, enabling the ingredients to set and the flavors to meld together before serving.

Notes

  • Achieve creamy, golden perfection by allowing the casserole to rest for 5 minutes after baking, helping the sauce thicken and flavors meld together.
  • Choose fresh, crisp cauliflower for the best texture and ensure slices are uniform to guarantee even cooking throughout the dish.
  • Gruyere cheese provides a rich, nutty flavor that elevates this low-carb side dish from ordinary to extraordinary, making it a crowd-pleasing keto option.
  • Covering with foil for the first 30 minutes prevents excessive browning while ensuring the cauliflower cooks thoroughly and becomes tender.
  • Use a mandoline or sharp knife to create thin, consistent cauliflower slices that will cook evenly and absorb the creamy sauce beautifully.
  • Opt for full-fat heavy cream to maintain the keto-friendly profile and create a luxuriously smooth, indulgent texture in this comforting casserole.
