Preheat oven to 450F. Place an empty baking sheet in the oven to preheat.
Cut Brussels Sprouts lengthwise into halves and transfer to a bowl. Season with 1/4 cup of the olive oil along with kosher salt, black pepper, garlic powder, and honey. Mix until all the brussels sprouts are evenly coated.
Once the baking sheet is hot, carefully set it on a heatproof surface and drizzle about 1/4 cup of olive oil evenly across the baking sheet.
Carefully add the mixed brussels sprouts and place them flat side down on the tray.
Roast the brussels sprouts in the oven for 25-30 minutes until crispy, flipping occasionally over once about halfway through cooking.
Notes
Try and buy evenly sized brussels sprouts at the store if you can. You'll want evenly sized sprouts so that they cook as evenly as possible and crisp up at the same rate. Otherwise, you may have some brussels sprouts that are burnt by the time the larger ones are crispy.Extra virgin olive oil - I recommend using a high quality extra virgin olive oil for this recipe. Aside from the seasonings, your oil is the key ingredient that will turn your brussels sprouts into a showstopper of a side, so you want to use a good quality oil.These brussels sprouts will absorb the oil in order to get crispy, so don't be afraid to add a little extra olive oil on them as needed.Depending on your oven and the size of your brussels sprouts, cooking times may vary. If possible use similar size brussels sprouts to ensure even cooking throughout and check the brussels sprouts occasionally until they are crispy to your liking!
