Instructions
Position a rack in the center of your oven and preheat to 425°F (220°C). Line a large rimmed sheet pan with a silicone baking mat or parchment paper.
Wash and thoroughly dry all vegetables. Halve baby potatoes (quarter any large ones), cut bell peppers into 1-inch pieces, slice zucchini into half-moons, and cut red onion into wedges keeping the root end intact.
Slice chicken sausage links on a slight diagonal into 1/2-inch thick rounds to maximize the browned surface area.
Add potatoes to a large bowl, drizzle with olive oil, then add sausage and remaining vegetables. Sprinkle in all seasonings and toss thoroughly for about 1 minute until every piece is evenly coated.
Spread the mixture in a single, even layer on the prepared sheet pan — place potatoes cut-side down and sausage slices flat. Do not overcrowd; use two pans if necessary.
Roast for 15 minutes undisturbed, then remove and flip/toss everything with a spatula. Return to the oven for another 12–15 minutes until potatoes are fork-tender and vegetables and sausage are caramelized.
Remove from oven, let rest 2–3 minutes, then scatter with freshly chopped parsley. Serve directly from the pan or transfer to a platter.
Notes
Don't overcrowd the pan: This is the single most important tip — spaced-out vegetables roast and caramelize; crowded ones steam and turn limp. Use two sheet pans if needed.
Dry your vegetables: Pat them dry with a paper towel after washing. Excess moisture prevents browning.
Use fully cooked sausage: This recipe is designed for pre-cooked links. If using raw chicken sausage, add 10–15 more minutes and verify an internal temperature of 165°F (74°C).
Cut potatoes smaller: Potatoes take the longest to cook, so keeping them halved or quartered ensures everything finishes at the same time.
Don't skip the flip: Flipping at the 15-minute mark ensures even browning on all sides of the sausage and vegetables.
Make-ahead tip: Slice everything and toss with seasoning up to 24 hours ahead; store covered in the fridge and add 2–3 extra minutes to roasting time.
Add delicate vegetables late: Cherry tomatoes or spinach should be added in the last 5–8 minutes so they don't overcook.
Storage: Refrigerate leftovers in an airtight container for up to 4 days, or freeze for up to 2 months.
Reheating: Best reheated at 375°F for 10–12 minutes on a sheet pan to revive crispy edges, or in a hot skillet with a splash of olive oil.
Variations: Try Mediterranean (olives, feta, oregano), Cajun (Cajun seasoning, corn), Fall Harvest (butternut squash, Brussels sprouts, apple), or Low-Carb (skip potatoes, double broccoli and cauliflower).
