How to Make Cauliflower Gratin with Leeks and White Cheddar
-
Preheat Oven: Begin by preheating your oven to 425°F (220°C). This step ensures that the gratin bakes evenly and achieves that golden brown crust we’re all craving.
-
Slice Cauliflower: Take your cauliflower head and slice it into ½-inch thick pieces, including the core. Keeping the core adds delicious texture and ensures even cooking in your gratin.
-
Layer Ingredients: In a 2-quart baking dish, drizzle a bit of olive oil. Start layering by placing a third of the sliced cauliflower and leeks in the dish. Season with kosher salt and black pepper for that flavor boost.
-
Repeat Layers: Continue layering the remaining cauliflower and leeks, seasoning lightly as you go. This helps to ensure every bite is full of flavor, so don’t rush this process!
-
Add Cream and Cheese: Pour heavy cream over the layered vegetables, ensuring it seeps down. Scatter the sharp white cheddar on top, and sprinkle a pinch more salt and pepper for good measure.
-
Cover and Bake: Cover your dish with foil and bake for 10-15 minutes. The goal is to get the cauliflower nearly tender, so keep an eye on it as it cooks.
-
Uncover and Finish Baking: Remove the foil and let it bake for an additional 35-40 minutes. You’re looking for a bubbly, golden brown top and thickened cream—just the way comfort food should be!
-
Cool Before Serving: Once done, let the gratin cool slightly before you serve it. This brief resting period allows the cream to thicken even more, ensuring each bite is rich and satisfying.
Optional: For an extra crunch, sprinkle seasoned breadcrumbs on top before your final bake.

Cauliflower Gratin with Leeks and White Cheddar Recipe FAQs
What type of cauliflower should I use for the gratin?
You’ll want to look for fresh, firm cauliflower without dark spots or blemishes. For the best flavor, choose a head that feels heavy for its size. If you can’t find cauliflower, broccoli is a delightful alternative that works wonderfully in this recipe!
How should I store leftover Cauliflower Gratin?
Store your gratin in the refrigerator in an airtight container for up to 3 days. Make sure it’s cooled completely before sealing to keep the moisture in and maintain that delicious creamy flavor.
Can I freeze my Cauliflower Gratin with Leeks and White Cheddar?
Absolutely! Allow the gratin to cool completely afterward and transfer it to an airtight container. It can be frozen for up to 2 months. I recommend portioning it out before freezing for quick meals later. Thaw in the fridge overnight before reheating.
What if my gratin seems too watery after baking?
If you find your gratin on the watery side, it might be due to excess moisture in the vegetables or heavy cream. To solve this, you can bake it a bit longer uncovered to allow steam to escape. Aim for a bubbly, thickened cream baked to a lovely golden crust—don’t be afraid to keep checking!
Are there any dietary restrictions I should be aware of with this recipe?
This delicious gratin is vegetarian and can be made gluten-free by using gluten-free breadcrumbs. For dairy-free options, swap out the heavy cream for cashew cream and use a non-dairy cheese. As always, double-check the ingredients of your specific products to ensure they meet your dietary needs.
Can I prepare the gratin in advance?
Yes, you can prepare the Cauliflower Gratin a day ahead! Simply layer everything in the baking dish, cover tightly, and refrigerate. On the day you plan to serve, just pop it in the oven when ready, adjusting the baking time as needed since it will be starting chilled. Enjoy the warm, homely goodness of this gratin with minimal fuss!
