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 the brussels 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 to form the cheese sauce.

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.

Step 6: Bake the cheesy brussels sprouts again for around 15 minutes, or until the top is a delicious crust of bubbly browning cheese!
