Kosher salt and freshly ground black pepper, to taste
Instructions
Preheat the oven to 425°.
Spread the broccoli florets on a baking sheet and sprinkle the top with the sesame oil, garlic, ginger, salt, and pepper. Stir everything around to coat the broccoli evenly. Put the pan in the oven and roast uncovered for 15 minutes.
Take the pan out of oven, stir the broccoli around, and scatter the butter slices evenly on top of the broccoli pieces. Drizzle the soy sauce evenly over the broccoli and butter, and put the pan back in the oven.
Roast for 5 more minutes and remove from the oven. Stir everything around to make sure the butter and soy sauce are in every bite.
