What is a Gratin?
A gratin is usually a veggie, but can be different ingredients too, topped with a browned crust usually consisting of melted cheese and sometimes breadcrumbs. It can be browned under the broiler or baked.
How to Make Roasted Brussels Sprouts Gratin
Step 1: Roast the Sprouts
Clean and trim the sprouts, if needed. Toss in olive oil, salt, and pepper. Roast at 450°F for 8-10 minutes.
Step 2: Make the Gratin Topping
In a small bowl, combine the panko crumbs, melted butter, parsley, garlic, salt and pepper. Then, set aside. Next, in a liquid measuring cup, add the cream and stir in a pinch of ground nutmeg. Set that aside as well until the sprouts are done roasting.
Step 3: Combine in Baking Dish
Once the brussels sprouts are done, add them to a 8x8 baking dish or 2 quart casserole dish. Cover the sprouts with the cream, then sprinkle the bread crumb mix over the sprouts and finish off with a layer of grated Parmesan cheese.
Step 4: Brown it
Bake the brussels sprouts gratin at 400°F for 15-20 minutes until the top is golden brown.
How to Clean and Trim Brussels Sprouts
I like to keep dishes as simple as possible and will often times buy already cleaned and trimmed brussels sprouts. However, sometimes they aren't available or I find a better deal on others. With that, it may be needed to clean and trim your sprouts.
To clean them rinse in cold water to get off any dirt, dust or residue. Then trim any discoloring part of the stem with a knife and remove any discolored outer leaves. Once cleaned and trimmed, proceed with the recipe as written. If you clean your brussels sprouts ahead of time, pat them dry before storing them in a container or zip top bag in the fridge.
