Trim Brussels Sprouts by removing the outer yellow or brown leaves. Cut off the woody stem on the bottom. Then slice them into four wedges.
Melt 1 Tablespoon of Butter in the pan. Make sure there is enough butter to coat the bottom of the pan. Once the butter starts to bubble, add the brussels sprouts. The pan should be hot enough for you to hear sizzling when you add the sprouts.
Do not flip or stir the Brussels sprouts for 1-3 minutes. This will allow them to char. Flip and repeat. When the pan starts to get dry add lemon juice. Continue to saute until the sprouts are soft on the inside and have browned on the outside (10 minutes).
