Brussel Sprouts Gratin

Brussel Sprouts Gratin is a delicious and easy vegetable side dish, made with Brussels sprouts, cream, shallots, garlic and gruyere. Vegetables never tasted so good. 

When it comes to vegetables that get a rap Brussel Sprouts are certainly at the top of the list for most people. That changes today because I am here to change even the big the biggest Brussels Sprouts hater into a Brussels Sprouts lover with this Brussel Sprouts au Gratin recipe.

This easy, decadent side dish is a great way to prepare Brussels Sprouts. It’ll be a vegetable that the whole family will love.

What is a gratin?

Basically a gratin is a dish, usually a vegetable of some kind, that is topped with a browned crust. The crust is usually made of bread crumbs and/or cheese. You’ve probably heard for potatoes au gratin. This is a twist, made with brussels. And it is absolutely divine.

What ingredients do you need to make Brussel Sprouts Gratin:

BRUSSELS SPROUTS: Cut in half. If the brussles sprouts are on the larger side, you can cut them in quarters. No need to do any other trimming!

OIL

SALT/PEPPER

BUTTER: salted or unsalted is fine.

SHALLOTS: Shallots will give a delicate onion flavor. You could use red onion in a pinch.

GARLIC

HEAVY CREAM: This is a decadent dish so don’t skimp out and use milk. Use the heavy cream!

GRUYERE CHEESE: The most common cheese used when making a gratin. It is a smooth melting Swiss cheese. It has a nutty, mild sweet flavor.

PANKO BREAD CRUMBS: I adore the crunch that panko bread crumbs add to dishes. It’s light and crunchy, perfect for the topping.

This recipe can easily be doubled if you’re feeding a crowd!

Store leftovers in the refrigerator and eat within a couple of days. Can be reheated in the oven. A minute or two under the broiler will crisp it back up again.
