Ingredients
Here’s what you’ll need to create this satisfying and delicious tray bake:
For the tray bake:
- 6 pork sausages (or your favorite variety)
- 1 lb baby potatoes, halved
- 2 bell peppers, sliced (I prefer red)
- 2 medium onions, sliced into wedges
- 2 tbsp olive oil
- 4 garlic cloves, crushed (skin on)
- 1 tsp smoked paprika
- ½ tsp dried thyme (or 3–4 fresh thyme sprigs)
- Salt and black pepper, to taste
For the mustard herb sauce:
- 3 tbsp Dijon mustard
- 2 tbsp heavy cream (or sour cream)
- 1 tbsp honey
- 1 tsp white wine vinegar
- 1 tbsp chopped fresh parsley
- 1 tsp fresh thyme leaves
Instructions
Follow these simple steps to create a rustic tray bake that’s full of flavor and perfect for any occasion:
- Preheat the Oven:
Preheat your oven to 400°F (200°C). Lightly grease a large baking tray or roasting dish. - Prepare the Vegetables:
Arrange the halved baby potatoes, sliced bell peppers, and onion wedges on the baking tray. Scatter the crushed garlic cloves among the vegetables. Drizzle with olive oil, then sprinkle with smoked paprika, thyme, salt, and pepper. Toss everything together to coat evenly. - Add the Sausages:
Nestle the sausages among the vegetables, ensuring they are evenly spaced to allow for even cooking. - Roast the Tray Bake:
Place the tray in the oven and roast for 25 minutes. Remove the tray, give the vegetables a stir, and flip the sausages. Return to the oven and roast for an additional 15–20 minutes, or until the potatoes are golden and tender, and the sausages are browned and cooked through. - Make the Mustard Herb Sauce:
While the tray bake is roasting, whisk together the Dijon mustard, cream, honey, vinegar, parsley, and fresh thyme in a small bowl. Adjust seasoning to taste. - Finish and Serve:
Once the tray bake is ready, drizzle the mustard herb sauce over the sausages and vegetables, or serve it on the side for dipping. Garnish with a few sprigs of fresh thyme for an elegant touch. - Enjoy:
Serve the tray bake straight from the dish for a rustic presentation. Pair with a side salad, crusty bread, or just enjoy it as-is for a comforting, one-pan meal.
Tweaks and Additions
Make this dish your own with a few creative twists:
- Add More Veggies
Include zucchini or aubergine for an Italian version or swap out the bell peppers for a mix of carrots, parsnips and swede for a British option. - Swap the Protein
Use chicken thighs, turkey sausages, or plant-based sausages for a lighter or vegetarian option. - Spicy Kick
Add chili flakes or use spicy sausages for extra heat. - Tangy Twist
Replace the honey with maple syrup or add a touch of horseradish to the sauce for a punchier flavor.
