Transform ordinary Brussels sprouts into a fancy side with this cheesy, dreamy au gratin. Every bite features tender sprouts swimming in a smooth, rich sauce packed with three different cheeses and gentle warming spices. This cozy dish turns an often-ignored veggie into the highlight of your holiday spread or fancy dinner night.
The first time this showed up at my Thanksgiving table, even folks who usually push Brussels sprouts aside went back for more. The mix of that silky sauce with perfectly done sprouts makes something that's both fancy and totally satisfying.
Key Ingredients
- Fresh Brussels Sprouts: They'll give you that perfect mix of tender inside with a bit of bite.
- Unsalted Butter: Creates a tasty foundation for your sauce.
- Fresh Garlic: Adds deep, aromatic flavor throughout.
- Heavy Cream: Brings that indulgent richness and smooth texture.
- Sharp Cheddar: Gives a bold, tangy kick that makes the sauce pop.
- Aged Parmesan: Adds a nutty, savory background flavor.
- Fontina: Melts like a dream for extra creaminess.
- Fresh Nutmeg: Offers warmth and subtle spice that balances everything.
- Garlic Powder: Boosts the savory notes for more flavor depth.
- Kosher Salt: Makes sure flavor spreads evenly through the dish.
- Black Pepper: Brings a mild heat that keeps things balanced.
- Cast Iron Skillet: Gives you the nicest browning and texture.
- Fresh Parsley: Adds a fresh, green finish.
- Quality Olive Oil: Provides a tasty final touch.
Making Your Dish
- Getting Sprouts Ready:
- Cut off the bottom ends and pull away any yucky outer leaves. Slice bigger sprouts in half through the stem so they'll cook evenly and soak up more sauce.
- Starting Your Sauce:
- Let the butter get foamy, then toss in your chopped garlic. Watch it closely so it doesn't burn. You want it smelling good but not turning brown.
- Whipping Up The Sauce:
- Pour in your cream bit by bit, stirring all the time for a smooth mixture. Add your spices and let them warm up in the cream to get their flavors going.
- Adding Your Cheese:
- Put your cheese in a little at a time, making sure each batch melts completely before adding more. This trick gives you the creamiest sauce possible.

When I was growing up, my grandma always said the trick to great au gratin was using freshly grated cheese. She'd never touch the pre-shredded stuff, saying it doesn't melt right. After making this dish for years, I totally get what she meant.
What To Serve With It
Make this side dish really shine by serving it with herb-covered chicken or a nice grilled steak. During the holidays, it goes great with turkey or glazed ham. Grab some crusty bread to mop up that extra sauce, or add roasted potatoes if you're feeling extra fancy.
Fun Twists
Switch this dish up to fit different tastes or occasions. Throw in some crispy bacon bits for smokiness. Mix up breadcrumbs with herbs and cheese for a crunchy topping. Make it super rich by adding some wild mushrooms, or spice things up with a sprinkle of red pepper flakes.
Storing Leftovers
Put any extras in a sealed container and they'll last about three days. Warm them up slowly in the oven to keep that creamy texture and stop the sauce from separating. If you want to make it ahead, put everything together except the cheese on top and keep it in the fridge for up to a day.
Tips For Success
Getting perfect Brussels sprouts au gratin comes down to good prep work. Take your time with the sauce and let the dish stay in the oven long enough to get that beautiful golden-brown top.
Getting The Right Bite
For the best texture, don't cook your Brussels sprouts too long. They should be tender but still hold their shape so they can soak up all that creamy sauce while keeping their structure.

Frequently Asked Questions
- → Can I make this dish before my guests arrive?
- You can get the sprouts ready and grate your cheese earlier, but for the best results, put it all together and bake it right before you plan to eat.
- → What if I'm missing some of the cheeses?
- The mix of three cheeses tastes amazing, but don't worry if you don't have them all. Any good melting cheeses you've got will work fine.
- → Will frozen Brussels sprouts work in this recipe?
- Stick with fresh sprouts if you can. Frozen ones tend to get mushy and release too much water when baked.
- → What's the best cooking dish to use?
- A cast iron pan or oven-safe pot works great because you can go from stove to oven, but you can always switch to a baking dish too.
- → Is the nutmeg really needed?
- Just a tiny bit of nutmeg makes cream sauces taste better and adds a subtle warmth to the dish that you won't even notice as nutmeg.
