Step 1

Preheat your oven to 400 degrees. Line a baking sheet with parchment paper.

Step 2

Place the whole brussels sprouts on the baking sheet and toss with the oil, salt, pepper, and cayenne. Add the lemon halves (cut side up) and the garlic to the baking sheet and drizzle with a little oil.

Step 3

Roast in the oven for 40 minutes, tossing the brussels halfway through.

Step 4

Let the garlic cool for a couple minutes then squeeze the cloves from the skin. Transfer the brussels to a serving dish, sprinkle with the roasted garlic, and squeeze the lemon over the top.
