Sausage Recipes NZ: Easy Kūmara Tray Bake

This New Zealand-style sausage and kūmara tray bake pairs browned pork or beef sausages with roasted kūmara, potatoes, red onion and apple. It is a practical one-pan dinner with crisp edges and a little tang from mustard and cider vinegar; sausage styles and family versions vary, so use the sausages you enjoy.

Ingredients

1½ lb (680 g) fresh pork or beef sausages, about 8 medium sausages
1¼ lb (570 g) kūmara, peeled if desired and cut into 1-inch (2.5 cm) chunks
12 oz (340 g) waxy potatoes, scrubbed and cut into 1-inch (2.5 cm) chunks
1 medium red onion (about 6 oz / 170 g), cut into thick wedges
1 medium firm apple (about 6 oz / 170 g), cored and cut into 8 wedges
2 tbsp (30 ml) olive oil
2 garlic cloves (about 6 g), finely chopped
1 tsp (1 g) chopped fresh rosemary, or ½ tsp (0.5 g) dried rosemary
½ tsp (3 g) fine salt
¼ tsp (0.5 g) freshly ground black pepper
1 tbsp (15 g) wholegrain mustard
1 tbsp (15 ml) apple cider vinegar
⅓ cup (80 ml) chicken or vegetable stock, preferably reduced-salt
2 tbsp (8 g) chopped fresh parsley, for serving (optional)

Instructions

Heat the oven to 425°F (220°C), or 400°F (200°C) fan bake. Set a rack in the centre. Line a large, rimmed roasting pan with baking paper if you want easier cleanup. Use a pan large enough to hold the vegetables in a mostly single layer; crowding traps steam and makes them softer rather than browned.
Prepare the kūmara and potatoes in even chunks so they cook at roughly the same rate. Put them in the pan with the onion wedges. Add the olive oil, garlic, rosemary, salt and pepper, then toss thoroughly. Spread everything out with a cut side of some chunks touching the pan. Roast for 20 minutes.
While the vegetables roast, stir the mustard and cider vinegar together in a small bowl. Pat the sausages dry if their casings are wet. There is no need to prick them: leaving the casings intact helps keep the juices in, and turning them during cooking encourages even browning.
Remove the pan carefully. Turn the kūmara and potatoes with a spatula, then nestle the sausages among them, leaving a little room around each sausage. Add the apple wedges. Stir the stock into the mustard mixture and pour it around the vegetables, rather than directly over the sausages, so the casings can brown.
Return the pan to the oven and roast for 12 minutes. Turn the sausages and gently toss the vegetables, then roast for another 10–13 minutes. The vegetables should be tender when pierced with a small knife and browned at the edges. If the sausages are done first, transfer them to a clean plate and let the vegetables finish; if the pan looks dry, add a splash of water or stock.
Check the thickest sausage with a food thermometer, inserting it from the end into the centre without touching the pan. Because sausages are ground meat, the USDA FSIS safe minimum internal temperature is 160°F (71°C). If they have not reached it, continue roasting and check again after a few minutes. Colour alone is not a reliable doneness test.
Rest the cooked sausages for 3 minutes while you stir the pan juices over the vegetables. Taste a piece of kūmara and add a pinch more salt or pepper if needed. Sprinkle with parsley, if using, and serve hot with the juices spooned over the top.

Tips

Choose similar-sized sausages. Thick sausages take longer than thin ones, so a tray with a mix may finish unevenly. If yours are especially large, give them more oven time and rely on the thermometer rather than the clock. Fresh sausages are intended for cooking; do not substitute fully cooked cocktail sausages and expect the same timing or texture.
Cut the vegetables evenly. Pieces around 1 inch (2.5 cm) are a good balance: large chunks can still be firm when the sausages are ready, while very small pieces can collapse. If your potatoes are particularly dense, cut them slightly smaller than the kūmara.
Use a roomy pan and turn once. A crowded pan will soften the vegetables as they release moisture. If you do not have a large roasting pan, divide the ingredients between two pans and rotate their positions halfway through roasting. Avoid stirring constantly, which can break up the tender apple and kūmara.
Adjust the tang to taste. Wholegrain mustard gives the pan juices texture and a mild bite. Dijon mustard works too, but makes a smoother, sharper sauce. If you do not have cider vinegar, use white wine vinegar; lemon juice is a possible substitute, though it gives a fresher citrus flavour.

Serving Suggestions

Serve this as a complete weeknight meal: the sausages provide the savoury centre, while kūmara, potatoes and apple roast alongside them. A crisp green salad or steamed cabbage adds freshness and balances the rich pan juices. For extra vegetables, serve with peas, green beans or broccoli cooked separately so they stay bright and do not overcrowd the tray.

If you want something to catch the juices, add crusty bread or warm dinner rolls to the table. A spoonful of chutney, tomato relish or extra mustard is a good optional condiment, especially if the sausages are mildly seasoned. For a more substantial meal, offer a simple slaw or buttered greens as well. Let diners spoon the stock, mustard and vinegar mixture from the pan over their own portions rather than pouring all of it over the crispest browned pieces.

Variations

Change the sausages: Use plain pork, beef or lamb sausages, or choose a herb-seasoned variety. Sausage flavours vary between makers, so taste the finished pan before adding extra salt. Chicken or turkey sausages can also work, but follow their package directions and check that the centre reaches the poultry safe minimum of 165°F (74°C), rather than using the ground red-meat temperature.

Swap the kūmara: Orange-fleshed sweet potato is the closest easy substitute and roasts in a similar way. It may be sweeter and softer, so check it a few minutes early. You can also use extra potatoes, parsnips or carrots; cut dense root vegetables into small, even chunks and allow more time if they are still firm after the sausages are cooked.

Make it more herby or spicy: Replace rosemary with 1 tsp (2 g) fresh thyme leaves or ½ tsp (1 g) dried thyme. For gentle heat, add ¼ tsp (0.5 g) chilli flakes to the oil and vegetables. Smoked paprika, about 1 tsp (2 g), adds a smoky note, but it will change the simple mustard-and-herb profile.

Use a different apple: A firm tart apple holds its shape and offsets the savoury sausages. A sweeter eating apple will soften more and make the pan juices sweeter. Pear wedges are another option, though ripe pears cook quickly; add them for only the last 15 minutes to reduce the chance of them turning mushy.

Storage and Reheating

Refrigerate leftovers within 2 hours of cooking, placing them in a shallow, covered container so they cool promptly. Store for 3–4 days in the refrigerator. For the best texture, keep the sausages and vegetables together with a little pan juice, but do not leave the tray sitting at room temperature while serving for an extended period.

To reheat, put a portion in an ovenproof dish with a spoonful of water or stock, cover loosely with foil and warm at 350°F (175°C) until hot throughout. You can also microwave in a covered, microwave-safe dish, stirring or turning the pieces halfway through. Reheated leftovers should reach 165°F (74°C); check the centre of a sausage with a thermometer. The microwave softens the browned edges, while the oven gives the vegetables a chance to regain some colour. Freeze portions in airtight containers for up to 2–3 months for best quality, then thaw overnight in the refrigerator and reheat to 165°F (74°C).

Frequently Asked Questions

Can I use different kinds of sausages in this tray bake?

Yes. Fresh pork, beef or lamb sausages are suitable, and the vegetables pair well with both plain and seasoned varieties. The cooking time depends on their thickness, so check each type with a thermometer. Ground pork, beef and lamb sausages need to reach 160°F (71°C); chicken or turkey sausages need to reach 165°F (74°C). If the sausages are already cooked, they only need reheating, and the texture may be less juicy if left in the oven for the full recipe time.

Do I have to peel kūmara?

No. The skin is edible, and leaving it on saves preparation time and helps the chunks keep their shape. Scrub the kūmara well and trim away any damaged areas. Peel it if the skin is tough or if you prefer a smoother texture. In New Zealand, kūmara is commonly available in different colours; any variety works, though colour and sweetness can differ.

Can I prepare the ingredients ahead?

You can chop the kūmara, potatoes and onion several hours ahead. Keep the cut potatoes and kūmara covered in cold water in the refrigerator to limit browning, then drain and dry them very thoroughly before tossing with oil; wet surfaces will steam rather than brown. Cut the apple just before cooking to reduce browning. Keep raw sausages covered and refrigerated, separate from ready-to-eat foods, until they go into the pan.

Why are my vegetables still firm when the sausages are cooked?

The chunks may be too large, the pan may be crowded, or the oven may be running cool. Remove sausages once they reach their safe internal temperature and continue roasting the vegetables in 5-minute increments until tender. Next time, cut the densest vegetables smaller, preheat the oven fully and spread the ingredients across a larger pan. Do not leave safely cooked sausages in the oven for a long time just to wait for the vegetables.

Can I make this recipe without mustard or stock?

Yes. Leave out the mustard and use 1 tbsp (15 ml) extra cider vinegar or lemon juice for a simpler, sharper pan dressing. If you have no stock, use ⅓ cup (80 ml) water; the result will be less savoury, but the roasted vegetables and sausage will still flavour the liquid. You can also omit the liquid for a drier, more deeply browned tray, keeping an eye on the pan so the garlic does not scorch.
