Ingredients
Here’s what you’ll need to whip up this wonderful Brussels Sprouts Gratin:
- 1 pound Brussels sprouts, trimmed and halved
- 2 tablespoons olive oil
- Salt and pepper, to taste
- 2 cups heavy cream
- 2 cloves garlic, minced (fresh garlic adds more punch than powdered!)
- 1 teaspoon Dijon mustard (for a lovely tang)
- 1 cup grated Gruyère cheese (or any cheese you love—Cheddar works beautifully too)
- 1/2 cup breadcrumbs (panko gives a lovely crunch)
- Fresh thyme, for garnish (optional, but lovely for presentation)
Step-by-Step Instructions
Ready? Let’s get cooking! Here’s how to prepare your Brussels Sprouts Gratin:
- Preheat your oven: Begin by preheating your oven to 375°F (190°C). A warm oven is essential for getting that beautiful, bubbly crust!
- Prepare the Brussels Sprouts: Trim the ends of the Brussels sprouts and cut them in half. Rinse them under cold water to clean. Pat them dry with a towel.
- Roast the Brussels sprouts: Toss the halved Brussels sprouts in a mixing bowl with olive oil, salt, and pepper to taste. Spread them out on a baking sheet in a single layer and roast for 15-20 minutes, until they start to caramelize and turn golden. This roasting step brings out their natural sweetness—don’t skip it!
- Make the creamy sauce: While the Brussels sprouts are roasting, combine heavy cream, minced garlic, and Dijon mustard in a saucepan over medium heat. Stir continuously until warm, making sure it doesn’t boil. Once combined, remove from heat and stir in 3/4 cup of the cheese until melted and creamy.
- Combine: When the Brussels sprouts are roasted, remove them from the oven and bring them to a baking dish. Pour the creamy cheese sauce over them, ensuring every sprout is covered.
- Add the topping: In a small bowl, mix the breadcrumbs with the remaining 1/4 cup of cheese. Sprinkle this crunchy mixture evenly over the gratin to create that irresistible crust that we all adore!
- Bake: Place the dish in your preheated oven and bake for 25-30 minutes, or until the top is golden brown and bubbly. Your kitchen will smell heavenly!
- Garnish and serve: Once it comes out of the oven, let it sit for a few minutes (if you can resist!). Garnish with fresh thyme before serving. Enjoy the delightful creation!

Pro Tips & Variations
Here are some tips to ensure your gratin is a success, along with some fun variations:
- Cheese Options: While Gruyère is traditional, feel free to experiment! Fontina, Asiago, or even a sprinkle of blue cheese can add a unique flair.
- Herbs: Fresh herbs like rosemary or sage can add an aromatic twist. Consider adding a pinch of nutmeg for depth in the cream sauce.
- Make it Vegan: Substitute the cream with coconut milk or cashew cream, and use nutritional yeast for a cheesy flavor. Dairy-free cheese options could also work nicely!
- Additional Veggies: Add in some cooked bacon or pancetta for a meaty kick, or mix in other vegetables like cauliflower or broccoli for more variety.
Serving Suggestions
This Brussels Sprouts Gratin is a star on its own, but I love to serve it alongside a crispy green salad and some crusty sourdough bread to soak up all that delicious cheese sauce. If you’re feeling a bit festive, why not pair it with roasted chicken or baked salmon? And for a cozy touch, a warm cup of herbal tea or a glass of white wine goes beautifully with it. You’ll have a complete, enchanting meal that feels so good!

Storage Tips
Have leftovers? Lucky you! Here’s how to keep your Brussels Sprouts Gratin fresh:
- Refrigerating: Store the gratin in an airtight container in the fridge for up to 3 days. Reheat it in the oven at 350°F (175°C) until warmed through, about 15-20 minutes.
- Freezing: You can freeze the unbaked gratin. Simply wrap it tightly in plastic wrap and then in aluminum foil. It will keep well for up to 2 months. To bake, thaw overnight in the fridge and then follow the baking instructions as above.
- Reheating: If reheating leftovers, I recommend doing so in the oven rather than the microwave to maintain the crispy topping. Just cover with foil initially to prevent over-browning!
FAQs
Can I use frozen Brussels sprouts instead of fresh?
Yes, you can use frozen Brussels sprouts! Just make sure to thaw them completely and drain any excess moisture before roasting. They might not have the same crunch as fresh, but they’ll still be delicious!
How can I make this dish gluten-free?
Substitute the breadcrumbs with gluten-free panko or crushed gluten-free crackers. You might also try almond flour or ground nuts for a different texture.
What can I do if I don’t like Brussels sprouts?
No worries at all! This creamy gratin method works beautifully with other vegetables too. Try cauliflower, broccoli, or even sliced zucchini for a delightful twist.
Can I prepare the gratin in advance?
Absolutely! You can prepare the dish ahead of time and keep it covered in the fridge. Just pop it in the oven when you’re ready to bake. Perfect for dinner parties or holiday gatherings!

There you have it, my dear food friends—a cozy, delicious Brussels Sprouts Gratin that’s sure to win over even the pickiest of eaters.
