Cauliflower Gratin

Cauliflower Gratin features tender cauliflower florets simmered briefly and combined with a creamy cheese sauce made from onion, garlic, almond milk, and melted Gruyere and Parmesan. Topped with grated cheese and breadcrumbs, then baked until bubbly and golden, it offers a satisfying creamy and slightly crispy texture with mild garlic and nutmeg notes. This dish serves well as a hearty vegetable side.

Description

This Cauliflower Gratin begins by boiling medium cauliflower florets until tender yet firm. A creamy sauce is prepared by sautéing onion and garlic in butter, then adding flour and spices including salt, pepper, and optional nutmeg to create a roux base. Unsweetened almond milk is gradually stirred in and brought to a boil, then cheese—primarily Gruyere with some Parmesan—is melted into the sauce to develop a smooth, rich texture.

The cooked cauliflower is placed in a casserole dish and covered evenly with the cheese sauce. Additional shredded Gruyere, Parmesan, and panko breadcrumbs or almond meal are sprinkled on top to create a gratin crust. Baking at 375°F produces a bubbly filling with a golden, slightly crisp topping that contrasts with the tender cauliflower beneath.

This gratin pairs well with roasted or grilled meats or can be served as a comforting vegetarian main. Leftovers should be kept in an airtight container in the refrigerator and can be reheated on the stovetop, oven, or microwave to preserve texture and flavor.

  6. Add cauliflower to prepared baking dish then pour sauce evenly over cauliflower.
  7. Top with remaining cheese and breadcrumbs or almond meal.
  8. Bake for 25-30 minutes until bubbly and top begins to brown. Broil for 2-3 min to brown the top more.
  9. Let cool for a few minutes then serve warm topped with fresh parsley.

Notes

  • Store leftovers in an airtight container in the refrigerator for up to 5 days.
