Ingredients

Brussels Sprouts: Choose deep green, firm sprouts and remove any wilted outer leaves. Cut larger brussels into halves, or quarters, so everything cooks evenly.

Bacon: Cook your favorite brand of savory bacon to a crisp finish for best results.

Cheese Sauce: Using heavy cream, cheddar cheese, garlic and mustard powder, then season to taste with salt and pepper, create a sauce that everyone will rave over.

Variations

Bacon not available? Try diced ham or slices of summer sausage. Or keep it vegetarian by omitting the bacon and fry brussels sprouts in oil, butter, or ghee.

While heavy cream is recommended, half-and-half can be used but will produce a thinner sauce. Experiment with ingredients that suit your menu or tastes. Try different types of cheese like Swiss, mozzarella, parmesan or gruyere cheese. A herb or a spicy southwest seasoning could work depending on the cheese pairing.

You can add keto-friendly veggies like sliced mushrooms, sundried tomatoes, or bell peppers for a bit more color or to stretch the casserole a bit further.

There are so many variations for the topping. You can make ‘au gratin’ topping by mixing keto breadcrumbs with the remaining cheddar cheese in Step 7. Add some sliced almonds to the top for a little crunch, and dust sprinkle with some shredded parmesan cheese.

How To Make Brussel Sprout Casserole

  1. Prepare Brussels sprouts (recipe below).
  2. Cook bacon until crisp and then crumble.
  3. Fry Brussels and transfer to a casserole dish.
  4. Add cream and seasonings and cook. Stir in cheese and seasonings.
  5. Pour cheese sauce over Brussels sprouts and top with bacon bits. Bake.

Tips For Srout-cess!

  • Fry Brussels sprouts until just tender and browned because they will continue to cook in the oven.
  • Most pre-shredded cheeses are packaged with anti-caking additives that prevent the best melt, so choose cheese by the block and grate it for a smoother sauce.
  • Pop the finished casserole under the broiler for a minute or two to get a crispier topping if you like.
  • Save and refrigerate that extra bacon grease to use in place of oil for other recipes. It’s great to use for sauteing meat or vegetables to add a smoky depth of flavor.

Serving and Storing Sprouts

This casserole really is a decadent choice for your holiday table along with either ham or turkey. But it’s so delicious, you will want to make it on repeat all year long.

Keep leftover Brussel sprouts casserole in a covered container in the refrigerator for up to 5 days. Reheat on the stovetop or pop it in the microwave.

You can freeze leftovers but it may separate when thawed due to the dairy. Whisk in a little more cream before reheating to help the sauce come together again. Freeze for up to 4 weeks in a freezer safe bag or sealed container.
