Creamy Cauliflower Gratin

This gratin really is over-the-top good. We recommend fresh cauliflower. You'll need either 2 large heads or 3 small/medium heads, about 12 cups after you cut them into medium-sized florets. If using frozen, you'll need 2 lbs, thawed. The recipe can easily be halved. Perfect for a holiday feast side dish!

Instructions

  1. Preheat the oven to 375°F and bring a large pot of water to a boil.
  2. Butter a 9x13 baking dish.
  3. Carefully add the cut cauliflower to the boiling water. Stir it around with a wooden spoon. Simmer for just 5 minutes then immediately drain. Set aside.
  4. Melt 2 tablespoon of the butter in a large saucepan, then add the onion and cook slowly over low heat until soft, 4 to 5 minutes.
  5. Add the thyme and then stir in the flour. Cook, stirring often, for 2 minutes.
  6. Slowly add the milk and cream, and whisk until all lumps are gone. Stir with a wooden spoon until thickened, about 5 to 15 minutes (heat the milk and cream before adding to expedite this process). The bechamel sauce should be slightly thicker than the consistency of gravy.
  7. Stir in the salt, pepper, and lemon juice. Next, add 1 cup of the cheese and stir until melted.
  8. Transfer the cauliflower to the prepared dish and pour the sauce over the top.
  9. Melt the remaining 2 tablespoon butter and combine with the bread crumbs and remaining cup of cheese in a medium bowl.
  10. Top the cauliflower mixture with the breadcrumb mixture.
  11. Bake, uncovered, for 30 to 45 minutes, until bubbly and golden on top.
  12. Let rest for at least 10 minutes before serving.

Notes

  • NOTE: Watch the video near the top of the recipe for visual guidance.
  • NOTE:
  • We recommend using fresh cauliflower but take care when cutting away the core and then cutting it into bite-sized florets. Always cut AWAY from the hand that is holding the cauliflower. Take your time.  If using frozen, you'll need 2 lbs, thawed, or steamed. 
  • Be sure to not allow the cauliflower to simmer for too long. 5 minutes is plenty of time, otherwise, it will get too soft and will be mushy and retain liquid that will release during the baking. For al denté cauliflower, skip simmering completely. 
  • The recipe can easily be halved if not serving a small gathering. 
  • Leftovers will keep in the fridge for up to 5 days and can be frozen (baked, or unbaked) for up to 2 months. Let thaw and then heat in a 375°F until bubbly and heated through. You may need to cover the dish with foil.
