Air Fryer Sausage and Vegetable Traybake
Why this recipe works
- All-in-one cooking: The sausages and vegetables cook together in the air fryer basket, giving a traybake feel with less oven time and minimal washing up.
- Tangy savoury glaze: Wholegrain mustard cuts through the richness of the pork sausages and helps coat the potatoes, onion and pepper with a punchy savoury finish.
- Crisp edges: Starting the vegetables before adding the sausages gives the potatoes time to soften while still developing browned, lightly crisp edges.

Common mistakes
- Overfilling the basket: A crowded air fryer basket traps steam and stops the vegetables browning properly. Cook in batches if your air fryer is small.
- Not checking thick sausages: Thicker sausages may need a little longer; they should be piping hot throughout with no pink remaining.
- Uneven potato size: Large potato pieces will lag behind the peppers and onion, so halve bigger ones to keep the cooking time even.
Ingredient notes
- Choose sturdy sausages: Pork sausages with a firm texture hold up well in the air fryer and brown neatly among the vegetables.
- Wholegrain mustard: Wholegrain mustard gives the glaze texture and gentle sharpness; Dijon can be used for a smoother finish.
- Chunky vegetables work best: Thick onion wedges and chunky pepper strips soften without collapsing during air frying.
Make-ahead tips
- Prep the vegetables ahead: The potatoes, onion and pepper can be cut ahead and kept chilled until you are ready to coat and cook them.
- Reheat in the air fryer: Leftovers reheat well in the air fryer at 190°C (375°F) until piping hot, which helps revive the browned edges.

Ingredients
Instructions
- Halve any larger potatoes so they are all roughly the same size. Cut the red onion into thick wedges and slice the red pepper into chunky strips. Preheat the air fryer to 200°C (390°F) for 3 minutes.
- In a large bowl, mix the olive oil, whole-grain mustard, dried thyme, fine sea salt and black pepper. Add the potatoes, onion and red pepper and toss until well coated. Tip the vegetables into the air fryer basket in an even layer.
- Air fry the vegetables for 15 minutes, shaking the basket once halfway through. Nestle the pork sausages among the vegetables. Continue to air fry for 15 to 18 minutes, turning the sausages once, until the potatoes are tender and the sausages are browned and cooked through.
- Rest for 2 minutes, then serve straight away. Scrape any mustardy juices from the basket over the sausages and vegetables before serving.
Recipe notes
Tips
- If your sausages are very thick, cook for an extra 3 to 5 minutes; they should be piping hot all the way through with no pink remaining.
- For even browning, avoid piling the vegetables too deeply; cook in two batches if your air fryer is small.
- Cut the potatoes evenly so they soften at the same rate as the peppers and onion.
Substitutions
- Replace Whole-grain mustard with Dijon mustard for a smoother glaze.
- Replace Dried thyme with Italian seasoning for a slightly different herb profile.
Storage
- Refrigerate up to 3 days
- Cool, then refrigerate in a sealed container for up to 3 days. Reheat in the air fryer at 190°C (375°F) for 6 to 8 minutes, shaking once, until piping hot.
