Choose Brussels sprouts that are bright green in color with tightly wrapped leaves.
We like to use garlic salt, but regular salt works just as well. On top of the salt you just need black pepper and olive oil. This creates a good base for any other additions after cooking such as parmesan cheese, cooked bacon, crumbled feta, etc.
If you plan on making a big batch for a holiday gathering, you can trim and slice the sprouts a day ahead of time and store them in an air-tight container in the refrigerator. Toss with olive oil, salt, and pepper right before roasting.
