How to Make Cauliflower Gratin
-
Prep Cauliflower: Begin by trimming the cauliflower into bite-sized florets. Cook the florets in simmering water for about 2-3 minutes until they are just al dente, then drain well and reserve the cooking water.
-
Make Cheese Sauce: In a saucepan, melt the butter over medium heat. Whisk in the flour until it’s smooth and absorbed. Gradually add 1 ½ cups of the reserved cooking water, whisking continuously until thickened. Then, stir in the heavy cream, seasonings, nutmeg, and one-third of the Gruyere until melted and creamy.
-
Combine: Gently fold the cauliflower into the cheese sauce until fully coated. Transfer this mixture into a greased casserole dish, and evenly sprinkle the remaining Gruyere cheese on top.
-
Prepare Topping: In a small skillet, sauté the garlic in a bit of butter until fragrant. Add the Panko breadcrumbs and fresh thyme, stirring until the breadcrumbs are golden and crispy. Sprinkle this mixture generously over the cauliflower.
-
Bake: Place the dish in a preheated oven set to 400°F and bake for 20 minutes, or until the top is golden brown and the gratin is bubbling at the edges. Allow to cool slightly before serving.
Optional: Garnish with extra fresh thyme for a burst of color and flavor.

Easy Baked Cauliflower Gratin Recipe FAQs
What should I look for when selecting cauliflower?
Absolutely! When selecting cauliflower, choose heads that are firm and compact, with tightly closed florets. Look for a creamy, even color; avoid any with dark spots or blemishes. If you notice any brown patches, it’s best to skip it, as it indicates aging.
How can I properly store leftover cauliflower gratin?
Very good question! Store any leftover cauliflower gratin in an airtight container in the refrigerator for up to 3 days. Ensure it has cooled to room temperature before storing to maintain quality. When you’re ready to enjoy it again, reheat it at 350°F for about 15-20 minutes until warmed through. Cover with foil to keep it moist, then uncover for the last few minutes to crisp the top.
Can I freeze cauliflower gratin, and if so, how?
Definitely! Freezing is a great option for make-ahead meals. To do this, prepare the gratin without baking it, then wrap it tightly in plastic wrap and aluminum foil to prevent freezer burn. It lasts up to 2 months in the freezer. When ready to bake, simply remove the wrap but keep the foil on top, bake directly from frozen at 400°F, and add an extra 10-15 minutes to your cooking time. This way, you’ll have a delicious, cheesy treat ready to go!
What if my gratin turns out watery?
A common issue, no worries! If you find your gratin is watery, it’s likely that the cauliflower wasn’t drained well enough after cooking. Ensure you thoroughly drain the florets to prevent excess moisture from ruining the texture. Next time, consider roasting the cauliflower beforehand for even less moisture—it enhances the flavor, too!
Are there any dietary considerations I should be aware of?
Great question! This recipe is vegetarian, but if you have any lactose intolerance or dairy allergies, you can substitute the Gruyere cheese with a high-quality vegan cheese and use plant-based cream. Always check ingredient labels when selecting substitutes to ensure they meet your dietary needs. Also, keep garlic in mind if anyone has allergies, as it’s a key ingredient!
How long can I keep the assembled unbaked cauliflower gratin in the fridge?
You can prepare the cauliflower gratin up to 48 hours in advance! Simply cover the assembled gratin tightly and refrigerate. When ready to bake, just pop it in the oven without the need for any extra prep. This makes meal planning a breeze, especially during busy holiday times!
