Flavorful Brussels Sprouts

Do you remember the way your mom used to make baked brussel sprouts when you were a kid? They often turn out bland. Even creamed brussel sprouts can be bland, but this recipe kicks up the flavor with loads and loads of cheddar and parmesan cheese!

Brussel sprouts have come into their own as a healthy, low carb alternative to other starchy vegetables like potatoes and corn. Not only are brussel sprouts packed with fiber, but this cheesy brussel sprouts recipe is low carb and keto friendly!

Feel free to add bits of bacon, sliced water chestnuts or even chicken for a full entrée! Everyone will be asking for seconds!

How to Cut Brussel Sprouts

Brussel sprouts are usually sold by the pound and pre-washed in bags at the supermarket. If you happen to find them at a farmer’s market or in the organic section, they might still be on their stalk, which can be anywhere from twelve inches to twenty four inches long!

Remove any torn or discolored leaves and rinse the brussel sprouts carefully. Pat them dry before cutting so they are easier to hold onto before cutting.

The best way to cut brussel sprouts is to slice them from the base off the stalk and then slice them vertically from the base all the way through, cleanly separating the halves.

How to Bake Brussel Sprouts Gratin

Rather than a thick cheesy sauce (like a Homemade Mac and Cheese has) these Brussels are sauteed and then baked with a simple light sauce so the flavor of the brussels really stands out.

  1. Season the cut brussel sprouts with salt and pepper.
  2. Saute in olive oil until just tender and slightly browned.
  3. Bring cream to a boil and whisk in cheese.
  4. Toss with brussels sprouts and bake!

A good brussel sprouts au gratin recipe calls for the perfect blend of cheese, in this case I use cheddar and parmesan cheese. Be sure the cheese is fully melted before pouring over the brussel sprouts.

This cheesy creamy brussel sprout gratin is easy to freeze and reheat, too! Chill overnight in the refrigerator before portioning into freezer bags. Label each back with the name and date and pop it in the freezer for an easy weeknight side dish everyone will love!
