Modern Bratwurst Traybake with Potatoes, Apple and Mustard

A bratwurst traybake brings the flavours of a German-style sausage supper into an easy one-tin format. Baby potatoes roast until tender and browned, while red onion and firm apple soften around the sausages, giving the dish a sweet-savoury edge without becoming heavy. Wholegrain mustard and thyme add sharpness, aroma and a slightly sticky coating as everything cooks together. Finished with warm sauerkraut, it has the familiar tang and richness of bratwurst with far less hands-on work, making it well suited to a straightforward lunch or relaxed weeknight meal.

Why this recipe works

  • Efficient traybake method: Potatoes, fruit, onions and sausages roast together on one tray, keeping the method simple while building flavour from the browned edges.
  • Balanced tang: Wholegrain mustard and sauerkraut cut through the richness of the bratwurst and keep the dish lively.
  • Sweet and savoury depth: Roasted apple and red onion soften into the mustardy coating, adding sweetness against the savoury sausages and potatoes.

Timing notes

  • Start the potatoes first: Giving the potatoes a head start helps them become tender before the apple and sausages are added.
  • Serve while hot: The traybake is best served straight from the oven, while the sausages are browned and the potatoes still have crisp edges.

Ingredient notes

  • Choose a firm apple: A firm tart-sweet apple holds its shape better during roasting and balances the richness of the bratwurst.
  • Use good wholegrain mustard: Wholegrain mustard adds texture as well as acidity, helping coat the potatoes, onion and apple as they roast.
  • Sauerkraut for contrast: Drained sauerkraut adds sharpness and freshness; warm it briefly so it keeps some bite without drying out.

Texture tips

  • Give everything space: Spread the ingredients in a single layer so the potatoes and sausages brown rather than steam.
  • Add the apple later: Adding the apple after the potatoes have started roasting keeps it soft and caramelised without collapsing completely.

Serving ideas

  • Serve with something green: A crisp cabbage salad, bitter leaves or simply dressed greens work well alongside the mustardy sausages and potatoes.
  • Beer pairing: A crisp lager or wheat beer suits the bratwurst, mustard and sauerkraut without overwhelming the traybake.

  1. Heat the oven to 220°C (430°F). Halve any larger potatoes so they are all a similar size, then tip them onto a baking tray and toss with the rapeseed oil, fine sea salt and black pepper.
  2. Roast the potatoes for 20 minutes, turning once halfway, until they are starting to colour. Meanwhile, cut the red onion into thick wedges and core the apple, then cut it into chunky wedges.
  3. Add the onion and apple to the tray, then dollop over the whole-grain mustard. Strip the thyme leaves from the sprigs and scatter them over everything, tossing well to coat.
  4. Nestle the bratwurst among the potatoes and return the tray to the oven. Roast for 20 minutes, turning the sausages once, until the sausages are browned and the potatoes are tender with sticky edges.
  5. Warm the sauerkraut by adding it to one corner of the tray for the final 3 minutes, just until heated through. Serve straight from the tray with a spoonful of sauerkraut alongside each portion.

Recipe notes

Tips

  • For the best browning, spread everything in a single layer and avoid overcrowding the tray; use a second tray if needed.
  • If your bratwurst are raw, make sure they are cooked through before serving; the juices should run clear and the centres should be piping hot.
  • If serving anyone who is pregnant, elderly, or immunocompromised, ensure the sausages are thoroughly cooked and the sauerkraut is heated until piping hot.

Substitutions

  • Replace the apple with pear for a softer, honeyed sweetness that still roasts well.
  • Replace fresh thyme with fresh rosemary for a more piney, robust flavour.

Storage

  • Refrigerate up to 3 days
  • Cool leftovers quickly, then refrigerate in a sealed container. Reheat on a baking tray at 200°C (390°F) for 12 to 15 minutes until piping hot, or in a frying pan over a medium heat with a splash of water to loosen the mustardy coating.
