Instructions
Heat the oven to 220°C / 425°F with a rack in the upper third. Line a large rimmed sheet pan with parchment (or lightly oil it).
Trim Brussels sprouts: slice off stem ends, remove any damaged leaves, then halve (quarter any large sprouts).
Core apples and cut into chunky wedges or large dice. Cut red onion into similar-size wedges, keeping a bit of root attached if possible.
In a large bowl, whisk together olive oil, Dijon mustard, whole-grain mustard, maple syrup, apple cider vinegar, salt, pepper, smoked paprika, red pepper flakes (if using), and thyme until glossy and emulsified.
Add Brussels sprouts and onion to the bowl and toss until evenly coated. Reserve a couple spoonfuls of dressing in a small cup or bowl for the sausage and apples.
Spread the coated Brussels sprouts and onion on the sheet pan in a single layer, with sprout cut sides facing down where possible (avoid crowding).
Roast for 12–15 minutes, until sprouts start to turn golden underneath and onion edges soften and color.
While the vegetables roast, slice the sausage into 1/2-inch rounds (score casing lightly if it tends to curl). Make sure apples are ready.
In the same bowl, toss sausage and apples with the reserved dressing until lightly coated. If it looks dry, drizzle in another 1–2 teaspoons olive oil.
Remove the pan after the first roast. Toss sprouts and onion briefly, then scatter the dressed sausage and apples evenly over the top, tucking some pieces down for direct heat.
Return to the oven and roast 15–20 minutes more, stirring once halfway through, until sausage is browned, apples are tender (not collapsing), and Brussels sprouts have deep golden crisp spots.
Optional finish: add butter pieces to the hot pan and toss gently to melt into a light gloss. Taste and adjust with more salt, pepper, or a splash of vinegar for brightness.
Rest 3–5 minutes, then serve from the pan or transfer to a warm platter.
