Crispy golden potatoes, juicy plant-based sausages, and everything roasted together in one tin so the flavours all mingle and get a bit caramelised and delicious. It's the kind of meal that makes your kitchen smell incredible and has everyone crowding around the oven before it's even done. Honestly, if you need a crowd-pleasing dinner on the table in 40 minutes, this is the one.

Make the tray bake

  • Take the tin out of the oven and place on a heat proof mat
  • Spoon the potatoes into the tin
  • Toss the unpeeled garlic cloves in to the tin
  • Season with salt and pepper and gently stir with a wooden spoon
  • Put the tin in the oven for 10 minutes

Add the sausages

  • Take the tin out of the oven and stir the potatoes around, lightly crushing a few if they’re soft
  • Add the sausages, tomatoes and thyme to the pan
  • Put the tin back in the oven for 20-25 minutes until the potatoes are golden, the tomatoes have split and the sausages are cooked through

  • Take 2 of the garlic cloves off the tray and squeeze the roasted garlic cloves into the food processor

Tips & Variations

  • Get the oil hot first: Don't skip warming the oil in the tin before the potatoes go in. It makes a real difference to how crispy everything gets. Trust us on this one.
  • Swap the sausages: We love this with classic vegan bangers but it works brilliantly with any plant-based sausage you've got in the fridge. Different brands give slightly different flavours so have a play around.
  • Add more veg: Throw in some red onion wedges, peppers, or cherry tomatoes when you add the sausages. They'll roast down beautifully and bulk everything out nicely.

Why This Works

The trick here is parboiling the potatoes first and then tossing them into already-hot oil in the tin. That's what gets them properly crispy on the outside rather than just soft all the way through. Roasting everything together in the same tin means the sausages and potatoes pick up each other's flavour as they cook, and you get all those lovely sticky, golden bits at the bottom of the tray.
