Prep: Preheat the oven to 400 degrees F. Line a baking sheet with foil for easy cleanup. Trim: Slice the very bottom off of the sprouts and remove the outer dry leaves. Slice the sprouts lengthwise. Leave any that are less than 1" in diameter whole.
Season: Add the Brussels sprouts to the foil-lined pan and drizzle with olive oil. Sprinkle with salt, pepper, garlic powder (and any other desired spices), and toss until evenly combined.
Arrange: Spread the sprouts in a single layer, cut side down, so they don't touch each other. Evenly sprinkle the bacon pieces in between the sprouts.
Bake: Bake for 18-25 minutes or until the Brussels sprouts reach the desired tenderness (check early). They should be tender but not mushy. If the bacon isn’t crispy when the sprouts are done, remove them and continue to cook the bacon until crispy (smaller Brussels sprouts will take less time to cook).
Glaze: Whisk the balsamic, honey, and sriracha in a small bowl. Drizzle over the cooked sprouts and toss to combine. Serve immediately.
