Easy Weeknight Meals UK: One-Pan Sausage Traybake

This easy UK weeknight meal is a one-pan sausage traybake with potatoes, red onion, peppers and a mustardy honey dressing. It needs little hands-on work, uses everyday supermarket ingredients and brings the sausages and vegetables to the table together.

Ingredients

1½ lb (680 g) British-style pork sausages, about 8
1¾ lb (800 g) baby potatoes, halved; quarter any larger ones
1 large red onion (about 8 oz/225 g), cut into wedges
2 bell peppers (about 10 oz/280 g total), deseeded and cut into 1-inch (2.5 cm) pieces
2 tbsp (30 ml) olive oil
1 tbsp (15 ml) wholegrain mustard
1 tbsp (15 ml) honey
1 tsp (5 ml) dried thyme
½ tsp fine salt (about 3 g), plus more to taste
¼ tsp freshly ground black pepper
1 tbsp (15 ml) red wine vinegar or cider vinegar
2 tbsp (8 g) chopped fresh parsley, optional

Instructions

Heat the oven to 425°F (220°C), or 400°F (200°C) for a fan oven. Set a large, sturdy roasting tin on the counter. It should be big enough for the potatoes and vegetables to sit in a mostly single layer; use two tins if necessary, since crowded vegetables steam rather than brown.
In a large bowl, whisk together the olive oil, mustard, honey, thyme, salt and pepper. Add the halved potatoes, onion wedges and pepper pieces, then toss until coated. Tip everything into the roasting tin and arrange the potatoes cut-side down where possible. Roast for 20 minutes.
Remove the tin carefully and turn the vegetables. Nestle the sausages among them, leaving a little space around each one. Roast for 20 minutes, then turn the sausages and stir the vegetables so they colour evenly.
Roast for a further 5 minutes, or until the potatoes are tender and browned and the sausages are thoroughly cooked. Check the centre of the thickest sausage with a food thermometer: pork sausages made from ground meat must reach the USDA FSIS safe minimum of 160°F (71°C). If they have not reached it, continue roasting and check again after 3–5 minutes. Avoid judging doneness by colour alone.
Take the tin out of the oven. Drizzle the vinegar over the vegetables, toss gently and taste for seasoning. Scatter with parsley, if using, and serve hot.

Tips

Choose sausages of similar size. Thick sausages can take longer than thin ones, so check the largest sausage in the centre with a thermometer. Keep raw sausage and its utensils separate from cooked food.
Cut potatoes evenly. Halve small potatoes and quarter bigger ones so they finish at about the same time. If using large floury potatoes, cut them into 1-inch (2.5 cm) chunks; peeling is optional.
Give everything room. A crowded tray traps moisture. Split the ingredients between two roasting tins if needed, and swap the tins’ oven positions halfway through cooking.
Adjust the dressing to taste. Use maple syrup instead of honey, or leave the sweetener out for a sharper finish. Wholegrain mustard gives texture; Dijon mustard works too but makes the dressing smoother and more pungent.

Serving Suggestions

Serve straight from the roasting tin with peas, green beans or steamed cabbage for an easy, balanced supper. A crisp green salad works well alongside the warm potatoes, while crusty bread can mop up the mustardy pan juices. For a more substantial meal, add a spoonful of butter beans or serve with a simple gravy. Check gravy labels if you need to avoid particular ingredients, and serve it separately so the vegetables stay crisp.

Variations

Change the vegetables: Swap the peppers for courgette chunks or thickly sliced carrots. Carrots take a little longer to soften, so cut them fairly small and roast them from the beginning. Add tender vegetables such as courgette for the last 20 minutes to prevent them becoming too soft.

Use another sausage: Chicken or turkey sausages are suitable, but their cooking time varies by size and product. Check the centre reaches 165°F (74°C), the USDA FSIS safe minimum for poultry. For vegetarian sausages, follow the packet instructions; they do not have the same meat temperature target.

Make it more herby: Use rosemary or dried oregano instead of thyme, or add a teaspoon of smoked paprika to the dressing. For a little heat, add a pinch of chilli flakes. These changes alter the flavour without changing the basic method.

Add greens: Stir in a couple of handfuls of spinach after roasting and let the heat from the tray wilt it. Alternatively, serve with separately cooked greens rather than adding them to the tin, which can release extra water.

Storage and Reheating

Transfer leftovers to a shallow, covered container and refrigerate within 2 hours of cooking. Keep for up to 3–4 days in the fridge. Reheat only the portions you need in a preheated oven at 350°F (180°C) until piping hot throughout; check that leftover sausages reach 165°F (74°C), the USDA FSIS temperature for reheated leftovers. A microwave also works: cover loosely, heat in short intervals, stir or turn the food and check the centre reaches 165°F (74°C). Reheat only once. Freeze cooled portions in a suitable sealed container for up to 2–3 months for best quality, then thaw in the refrigerator before reheating.

Frequently Asked Questions

Can I prepare the traybake in advance?
Yes. Cut the vegetables and mix the dressing up to a day ahead, then store them separately in covered containers in the refrigerator. For the best browning, toss everything together just before roasting. Do not leave raw sausages or prepared vegetables at room temperature while you wait.

Can I use frozen sausages?
Thaw them in the refrigerator before cooking unless the packaging specifically gives safe instructions for cooking from frozen. Frozen sausages can cook unevenly on a tray, so do not rely on the recipe’s timing alone; use a food thermometer and check the centre reaches 160°F (71°C) for pork or beef sausages, or 165°F (74°C) for poultry sausages.

Why are my potatoes still firm?
They may be larger than the recipe pieces, or the tray may be crowded. Cut them into even, bite-sized pieces and continue roasting until a knife slides easily into the centre. If the sausages are already done, remove them to a clean plate, cover loosely, and return the potatoes to the oven.

Can I make this recipe without honey?
Yes. Leave it out for a less sweet dressing, or use the same amount of maple syrup. The honey helps balance the sharp mustard and vinegar but is not needed for the traybake to cook properly.

How can I make the vegetables brown rather than soggy?
Use a large metal roasting tin, preheat the oven fully, and avoid piling the vegetables on top of one another. Dry washed vegetables before tossing them with oil. If your tray is small, roast the vegetables in two tins rather than squeezing them into one.

Can I make this recipe gluten-free?
Usually, but check the sausage, mustard and any gravy or sides for gluten-containing ingredients, since sausages and prepared condiments vary by brand. Choose products labelled gluten-free and keep preparation surfaces and utensils free from crumbs.
