I know that Brussels Sprouts Casserole doesn’t sound that exciting or like a dish your kids will eat, but hear me out! We’ve added in bacon, cheese, and a crispy panko topping that makes this casserole absolutely delicious. This is one hundred percent Thanksgiving comfort food that we love so much we’ll be making it year round. Start your grocery list now! I promise this is a recipe you’ll want to make ASAP. It’s hearty, savory, and filled with the best comfort food ingredients. And if casseroles aren’t your thing, call it Brussels Sprouts Gratin, it sounds fancier but it is the same thing, ha!
How to Make Brussels Sprouts Casserole
First, make the Parmesan panko topping. Use good Parmesan cheese, not the stuff in the can. Don’t skip the lemon zest, it really brighten things up. This casserole is made in a cast iron skillet. Everything is done in one skillet for minimal dishes and maximum taste! The bacon is cooked first and removed from the pan, but don’t get rid of the bacon fat. You want to cook the sprouts, onion, and garlic in the fat for extra flavor.Cook the Brussels sprouts until they are slightly charred and still a little crisp. They will finish cooking in the oven and we don’t want to end up with mushy Brussels sprouts. Use a mixture of Gruyere cheese and mozzarella cheese. Look for Gruyere at the cheese counter at your grocery store. If you can’t find it, white cheddar will work too. Everything gets cooked in heavy cream, sprinkled with cheese, and finished off with the Panko topping. Finish it off in the oven until it’s bubbly, browned, and absolutely delicious looking.
How to Store
Store leftovers in a sealed container for three to five days in the refrigerator. You can reheat in the oven or in the microwave. Everyone always fights for these leftovers after Thanksgiving! You can technically freeze the casserole for up to two months, but the sprouts will get a little mushy. I recommend polishing it off the first time around, which shouldn’t be a problem.
