If you haven’t already, remove the stem from the Burssels sprouts and slice them in quarters. Whisk together the syrup, olive oil, and sea salt. Toss everything in a bowl and mix until all sprouts are coated.
Line a baking tray with parchment paper and pour the sprouts on top in one even layer.
Bake for 18 minutes. Remove pan and stir/flip the sprouts moving the middle ones to the outer layer and vice versa.
Bake for another 15 minutes. Turn the oven off and let cook/cool for 5-10 more minutes before serving.

Notes
How to cut them to make sure they come out crispy:
First de-stem them. To do this, simply cut the bottom off the Brussels sprouts (when raw) but take more than you need to.
Some of the leaves should fall off and that's exactly what you want!
Then, slice them in half and into quarters. You want them small.
Finally, when the Brussels sprouts are in the bowl, toss them a bit with your hands. The more leaves that fall off and the smaller the actual sprouts, the crispier the maple-roasted Brussels sprouts will come out.
Make sure to spread the candied Brussels sprouts in just a single layer on the baking sheet. Too many piled on top of each other means that they won't crisp up and take forever to cook.Keep an eye on them cooking in the last 3 minutes. You want them to start turning brown but not burn.
