Step 1

Preheat oven to 425 degrees F.

Step 2

Wash and then cut off any brown ends of the Brussels sprouts. Next, cut them in half or into quarters lengthwise. Slice onion if using.

Step 3

Mix them (and sliced onion if using) in a bowl with olive oil, salt, and pepper. Place them cut side down on a sheet pan lined with foil and roast for 20 to 25 minutes, until crisp on the outside but tender on the inside.PRO TIP: For extra crispy Brussels, add a little extra olive oil to the pan before placing your veggies in it.

Step 4

Flip the Brussels sprouts halfway through the cooking time to brown them evenly. Sprinkle with a tiny bit more sea salt and serve immediately.
