In a large skillet (I prefer cast iron), heat the olive oil over medium high heat.
Add the Brussels sprouts and sauté for about 10 to 15 minutes, stirring occasionally, until sprouts are mostly dark golden brown and tender. I like the sprouts to get charred and crispy.
Once caramelized, add the garlic and cook for 1 more minute.
Remove the skillet from the heat and stir in the lemon zest and lemon juice. Place the Brussels sprouts on a platter or in a serving bowl and garnish with Parmesan cheese and chopped nuts. Season with salt and pepper, to taste. Serve immediately.
Notes
Reheat in a hot skillet, air fryer, or oven so they crisp back up.
