Step 1

Heat the oven to 450°F.

Step 2

Add the bacon to a sheet pan and roast for 5 minutes.

Step 3

While the bacon is roasting, add the Brussels sprouts, onion, garlic, olive oil, salt, and pepper to a mixing bowl. Toss to combine.

Step 4

After the bacon has been in the oven for 5 minutes, remove the sheet tray and add the Brussels sprout mixture. Use a spatula to carefully toss, then arrange the Brussels sprouts so they’re evenly spread out and facing flat side-down.

Step 5

Roast the Brussels sprouts for 20 to 30 minutes—shuffling the sprouts with a spatula and rotating the sheet pan halfway through—until the bacon is crisp and the Brussels sprouts are tender and beginning to char. Drizzle with maple syrup, carefully toss again, then return to the oven for another few minutes, or until the Brussels sprouts are as crispy as you like them.

Step 6

As soon as you pull the sheet pan from the oven, drizzle the Brussels sprouts with apple cider vinegar and sprinkle with red pepper flakes. Toss, taste (watch out, it’s hot!), and adjust the salt, spice, and vinegar as needed.

Step 7

This is great served hot, warm, or at room temperature.
