Brussels Sprouts gratin is a holiday dish that you never knew you needed, but can’t live without.
Brussel sprouts are one vegetable that you know you should eat more of, but quite frankly may not want to.
Enter this incredible recipe. When you taste one bite of these cheesy brussels sprouts you will understand why they are now a family favorite recipe.
Ingredients to make brussels sprouts gratin
- fresh brussels sprouts: frozen brussels will not work in this recipe
- yellow onion and fresh garlic: a must have for flavor
- heavy cream: to make the rich creamy sauce for the brussel sprouts
- fresh grated sharp white cheddar cheese
- salt & pepper: to taste
How to make brussels sprouts gratin
Step 1: Prepare a pound of brussels sprouts. Cut off the ends, and remove any shriveled outer leaves from each brussel.
Cutting the brussels sprouts into pieces
Step 2: Cut each brussel sprout into thirds, as pictured below. You could cut them in half, but I love that they get an even yummier texture when super thin like this!
Step 3: Place the brussel sprouts in a small baking dish and spray with olive oil. Roast at 400 degrees for around 20 minutes, until softened.
Making the cheese sauce
Step 4: While your brussels are roasting, it’s time to make that yummy cheese sauce!
Cook the garlic and onion until softened, then stir in some heavy cream, half of the fresh grated sharp white cheddar cheese, and salt and pepper.
If you prefer another cheese, fresh grated parmesan would also be delightful in this dish.
I recommend that whichever cheese you pick, just be sure to grate it yourself from a block. The flavor difference is well worth it!
Step 5: When the brussels have finished cooking, pour the white cheddar cream sauce over the top and sprinkle on the remaining sharp white cheddar cheese.
Baking the brussels sprouts gratin in the oven
Bake the cheesy brussels sprouts again for around 15 minutes, or until the top is a delicious crust of bubbly browning cheese!
This is a great side for dinner and I promise even if you have never liked brussels sprouts, you will go crazy after tasting one bite.
This just may be your new favorite Thanksgiving recipe!
