Here’s how we roast Brussels sprouts to be crispy on the outside and tender inside. Our easy two-part method guarantees the best roasted Brussels sprouts. The ham is optional and can be left out or substituted for turkey, bacon, turkey bacon, or tofu. If you use bacon, we suggest rendering some of the fat first instead of adding raw bacon to the tops of the sprouts. This way, you can use some of the rendered bacon fat instead of the olive oil called for in the recipe.
