Sheet Pan Sausage and Vegetables
Not rated yet. Be the first.
Potatoes go in first, sausage and peppers follow, and a splash of vinegar and mustard finishes it. Forty-five minutes, one pan, and everyone gets the crispy corner they were hoping for.
The short version
Roast cut-up potatoes and onion at 425°F for 10 minutes, add sausage chunks and peppers, roast 20 minutes more, toss with vinegar and mustard. About 45 minutes, and the sausage should reach 160°F inside.
What makes ours better
what we fixed so you don’t have to
-
Give the potatoes a head start. Potatoes take about 30 minutes to get crisp and peppers and sausage take about 20. Starting the potatoes alone means everything finishes together.
-
Cut the sausage into thick coins. Whole links brown on one side only. Coins give you two flat browned faces each and render their fat over the vegetables, which is the seasoning.
-
Finish with vinegar and mustard. Hot roasted vegetables and fatty sausage taste heavy without something sharp. A spoon of vinegar and whole-grain mustard tossed in at the end wakes the whole pan up.

Steps
deep breath. you’ve got this.
-
Heat the oven and pan
Set a rack in the upper third of the oven and heat it to 425°F. Slide an empty large rimmed sheet pan onto the rack while the oven heats.
-
Start the potatoes
Toss the potatoes and onion on a second tray or in a big bowl with 1 tablespoon of the oil and half the salt. Carefully pour them onto the hot pan, cut sides down for the potatoes. You should hear a sizzle. Roast for 10 minutes.
About 10 min. Cook mode has a timer for this step.
-
Add the sausage and peppers
Toss the sausage coins and peppers in the same bowl with the remaining 2 tablespoons oil, the rest of the salt, the oregano and the black pepper. Pull the pan out, scatter them over the potatoes, and tuck the garlic cloves in among them. Spread everything into a single layer with a little space between pieces.
A crowded pan steams instead of browning. If the pieces are touching everywhere, use two pans.
-
Roast until browned
Roast for 20 to 25 minutes, stirring once at the halfway mark. The potatoes should be crisp at the edges and tender in the middle, the peppers charred in spots, and the sausage browned, with no pink at the center. Fresh sausage is done at 160°F inside. Precooked sausage just needs to be browned.
About 20 min. Cook mode has a timer for this step.
-
Toss with vinegar and mustard
Pull the pan out. Drizzle the vinegar over the hot vegetables, add the mustard in a few dollops, and stir everything around on the pan so the mustard melts into the pan juices. Scatter the parsley over the top and serve from the pan.
Good to know
things I learned the hard way, so you can skip that part
- Swap the potatoes for sweet potato chunks, or the peppers for broccoli florets or zucchini half-moons. Hard vegetables like carrots and Brussels sprouts go in with the potatoes. Soft ones like zucchini go in with the sausage.
- Chicken sausage cooks a little faster and has less fat to render. Add an extra tablespoon of oil and check it at 18 minutes.
- Cut all the vegetables to roughly the same size. Uneven pieces are the usual reason one is raw while another burns.
- Storage. Fridge in an airtight container, 4 days. Reheat on a sheet pan at 400°F for 10 minutes to bring back the crisp edges. The microwave works but softens them.
Questions, answered
the questions my cousins text me
What kind of sausage is best for a sheet pan dinner?
Fresh Italian sausage gives the most flavor and renders the most fat for the vegetables. Smoked sausage like kielbasa or andouille is already cooked, so it browns faster and is hard to overcook.
Can I use whole sausage links instead of slicing them?
Yes. Nestle whole links among the vegetables and roast them the full 25 minutes, turning once, until they hit 160°F inside. Slicing gives you more browned surface and a shorter cook.
Why are my sheet pan vegetables soggy?
Too much on the pan, or a cold pan. Spread the food in a single layer with gaps, heat the pan first, and use two pans if you have to. Wet vegetables also steam, so dry them well after washing.
Can I prep this ahead?
Cut the vegetables and sausage up to a day ahead and keep them in separate containers in the fridge. Toss with the oil just before roasting.
How do I know the sausage is cooked?
Fresh pork or chicken sausage should read 160°F in the center of a thick coin and show no pink. Precooked smoked sausage only needs to be heated through and browned at the edges.
