Parmesan Cheese: Freshly grated parmesan adds a nutty depth; don’t skimp on this one!
Bacon Bits: Cook up some crispy bacon beforehand; its smoky flavor complements the sprouts beautifully.

How to Make Rich Keto Brussels Sprouts Au Gratin
Preheat Your Oven: Start by preheating your oven to 375°F (190°C). Grease a baking dish generously with butter to set the stage for cheesy perfection.
Prepare The Brussels Sprouts: Rinse your Brussels sprouts under cold water. Trim off any tough ends and slice them in half lengthwise so they cook evenly and absorb all that cheesy goodness.
Cook The Bacon: In a skillet over medium heat, cook your bacon bits until crispy. The aroma will fill your kitchen with pure bliss—trust me, you’ll want to save some for later!
Mix The Creamy Base: In a mixing bowl, combine heavy cream with garlic powder, salt, and pepper. Stir until well blended—this creamy concoction will be the glue that holds everything together.
Combine Ingredients: In your greased baking dish, layer half of the Brussels sprouts followed by half of the cooked bacon bits. Pour half of the creamy mixture over them and then repeat layers until everything is used up.
Top With Cheese: Finally, sprinkle generous amounts of sharp cheddar cheese and grated parmesan on top. This cheesy blanket will create a beautiful golden crust while baking—it’s what we live for!
Bake To Perfection: Place in your preheated oven and bake for about 30-35 minutes or until bubbly and golden brown on top. Let it cool slightly before serving—you don’t want anyone burning their tongue on that molten cheese!
