The recipe marries the earthy bitterness of brussels sprouts with the silky richness of coconut milk, elevated by warm nutmeg and bright lemon zest. Perfect as a showstopping side or a satisfying plant-based main, this gratin delivers comfort without compromise. To begin, preheat your oven to 180°C. Lightly grease a heatproof baking dish with a high-quality oil sprayer for even, minimal coverage.
About This Dish
Gratins have long been a cornerstone of French cuisine, traditionally heavy with cream and cheese. This vegan interpretation swaps dairy for coconut milk, creating a luscious sauce that clings to every sprout half. The technique of blanching the sprouts—briefly boiling then shocking in cold water—ensures they remain vibrant green and tender-crisp, not mushy. A final breadcrumb topping adds a satisfying crunch that contrasts the velvety coconut base. For an even more robust outcome, consider roasting the sprouts first in a commercial countertop convection oven to intensify their natural sweetness before assembling the gratin.
Ingredients
- 500 g Brussels sprouts
- 400 ml coconut milk (full-fat for best creaminess)
- 2 tbsp vegetable oil (plus extra for the dish)
- 1 lemon (zest only)
- 1 tsp freshly grated nutmeg
- Salt to taste
- Freshly ground black pepper to taste
- Breadcrumbs (for topping—optional but recommended)
Using high-quality coconut milk is key; if you prefer to make your own, an immersion blender will help you achieve a silky consistency. For the breadcrumbs, you can pulse stale bread in a food processor for a coarse, fresh texture.
Step-by-Step Instructions
- Preheat and prepare: Preheat oven to 180°C. Grease a baking dish with a little vegetable oil using an oil sprayer for even coverage.
- Blanch the sprouts: Halve the Brussels sprouts. Bring 2 liters of salted water to a boil. Add the sprouts and cook uncovered over medium heat for 4 minutes. Drain in a colander and immediately rinse under cold water to stop cooking. Let the liquid drain completely, then pat dry on a clean kitchen towel. For a quicker blanch, consider using a microwave pressure cooker to steam them in minutes.
- Prepare the coconut sauce: Wash the lemon in hot water with a brush, then finely grate the zest. Whisk together the coconut milk, lemon zest, nutmeg, 1 tablespoon vegetable oil, salt, and pepper until well combined. For extra smoothness, you can briefly blend the sauce with an immersion blender.
- Assemble and bake: Arrange the blanched sprouts cut-side up in the prepared dish. Pour the coconut sauce evenly over them. Sprinkle breadcrumbs on top. Bake in the center of the oven for 30–35 minutes, until the top is golden and the sauce bubbles around the edges. If you prefer a deeper browning, finish under the broiler or use an air fryer for the final few minutes.
Tips for Success
- Don’t skip the blanch: It removes raw bitterness and sets the sprouts’ vibrant color.
- Use full-fat coconut milk for the richest sauce. Light versions may curdle.
- Toast the breadcrumbs in a dry pan before sprinkling for extra crunch.
- Adjust seasoning generously—coconut milk can mute flavors; a pinch more nutmeg or salt brightens the dish.
- If preparing ahead, assemble the gratin (without breadcrumbs) and refrigerate. Add crumbs just before baking. Store leftovers in an airtight container in a refrigerator for up to 3 days.
Variations
Spice it up: Add a pinch of chili flakes or curry powder to the coconut sauce for a warming kick.
Add protein: Toss in toasted chickpeas or crispy tofu cubes before baking.
Swap the vegetable: Try cauliflower florets or broccoli for a similar gratin.

FAQ
Can I make this gratin nut-free?
Yes, coconut is a fruit, not a tree nut, but if you have specific allergies, substitute with oat cream or sunflower seed milk. For a silky alternative, use an immersion blender to blend soaked cashews instead of coconut milk.
What can I serve with this gratin?
It pairs wonderfully with roasted tofu, quinoa, or a simple green salad. For a celebratory meal, serve alongside a glass of sweet wine with high alcohol content to cut the richness.
How do I prevent the coconut sauce from separating?
Ensure the coconut milk is well shaken before measuring, and avoid over-boiling the sauce. If it separates, a quick blitz with an immersion blender will re-emulsify it.
Can I freeze this gratin?
Freezing is not recommended as the coconut sauce may become grainy upon thawing. It’s best enjoyed fresh or refrigerated for up to 3 days. Reheat in an air fryer for a crisp topping.
What equipment do I need?
A sharp chef’s knife, a large pot, a baking dish, and a zester or fine grater. For effortless preparation, a food processor can quickly make breadcrumbs. If you’re serving a crowd, consider a commercial countertop convection oven for even baking.
This vegan coconut gratin with Brussels sprouts proves that plant-based comfort food can be both elegant and deeply satisfying. The contrast of tender sprouts, creamy coconut, and crunchy breadcrumbs will win over even the most skeptical diners. For a festive touch, finish with a drizzle of chocolate-covered raisins scattered atop—an unexpected but delightful garnish. Or serve with a side of George Howell coffee for a sophisticated ending.
