- This casserole is sure to be savory, creamy, and crispy in every bite.
Ingredients
Brussels Sprouts: Choose deep green, firm sprouts and remove any outer leaves that are wilted. Halve or quarter them so they cook evenly.
Bacon: Any flavor of bacon will work in this recipe as will diced ham or slices of summer sausage. For a vegetarian casserole, omit the bacon and fry brussels sprouts in oil, butter, or ghee.
Cheese Sauce: Heavy cream and cheddar melt together perfectly in this recipe. Half-and-half will produce a thinner sauce but can be used if desired. Besides garlic and mustard powder, try a simple herb blend, or a spicy southwest blend to match the menu.
Variations: Feel free to add keto-friendly veggies like sliced mushrooms, sundried tomatoes, or bell peppers. Make a ‘gratin’ topping by mixing keto breadcrumbs with the remaining cheddar cheese in Step 7. Sliced almonds can also be added to the top for a little crunch and color.
How To Make Brussel Sprout Casserole
- Prepare Brussels sprouts (recipe below).
- Cook bacon until crisp and then crumble.
- Fry Brussels and transfer to a casserole dish.
- Add cream and seasonings and cook. Stir in cheese and seasonings.
- Pour cheese sauce over Brussels sprouts and top with bacon bits. Bake.
Tips For Success
- Save extra bacon grease in a jar in the refrigerator and use it in place of oil when sauteing meat or vegetables for a smoky depth of flavor.
- Fry Brussels sprouts until just tender and browned as they will continue to cook in the oven.
- Most pre-shredded cheeses are packaged with anti-caking additives that prevent the best melt, so if you can, grate the cheddar from a block for a smoother sauce.
- Pop the finished casserole under the broiler for a minute or two to get a crispier topping if you like.
Leftover Suggestions
Keep leftover Brussels sprouts casserole in a covered container in the refrigerator for up to 5 days and freeze leftovers in a freezer-safe container for up to 4 weeks. It may separate when thawed due to the dairy, simply whisk in a little more cream before reheating! Reheat on the stovetop or microwave.
