Set a large, heavy-bottomed skillet over medium-high heat and add the oil

When oil begins to smoke, carefully add the Brussels sprouts, cut side down (as best as you can, doesn’t have to be perfect)

Season with Kosher salt and pepper and allow to cook, undisturbed, for 2-4 minutes, until the sprouts have gotten a deep caramelization

Toss the sprouts and continue to cook, stirring occasionally, for an additional 3-5 minutes, until they are tender but still have a bite (al dente)

Remove the pan from the heat, then add the maple syrup, butter, and 2 tablespoons of water

Stir until all the sprouts are nicely glazed

Taste and adjust the seasoning if needed

Then, transfer the mixture to a serving dish and sprinkle with pecans, if using

Serve immediately.
