How to make brussels sprouts gratin

First, start off with a pound of brussels sprouts.

Cut off the ends, and remove a few outer leaves from each brussel. 

Cutting the brussels sprouts into pieces

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!

Place the brussels in a small baking dish and spray with olive oil.

Roast for around 20 minutes, until softened. 

Making the cheese sauce for the brussels sprouts gratin

While your brussels are roasting, it’s time to make that yummy cheese sauce!

Start with fresh garlic and onion for flavor, then stir in some heavy cream, 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!

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