Ingredients for Sheet-Pan Sausage with Peppers and Onions

Here’s what you’ll need to make this simple, flavorful dish:

1 large yellow onion, sliced

1 tsp salt

How to Make Sheet-Pan Sausage with Peppers and Onions

This dish couldn’t be simpler to make—just follow these easy steps and you’ll have a delicious dinner in no time. I’ve made this so many times I could do it in my sleep, but here’s exactly how I get perfect results every time.

Prep Your Sheet Pan

First things first—preheat your oven to 400°F (200°C). While that’s heating up, grab your sheet pan and toss the sliced peppers and onions with olive oil, salt, pepper, oregano, and garlic powder. Really get in there with your hands to make sure every piece is nicely coated—this is where all that flavor starts!

Arrange and Roast Your Sheet-Pan Sausage

Now nestle those sausages right on top of the veggies—no need to be fancy, just space them out evenly. Slide the pan into the oven and let the magic happen for about 15 minutes. Then comes the crucial flip! Turn each sausage over so they brown evenly on both sides. Give everything another 10-15 minutes until the sausages are golden and cooked through (they should reach 160°F internally if you want to check). The peppers and onions should be beautifully caramelized by now—that’s when you know it’s perfect!

That’s seriously it! Just plate it up and watch how fast it disappears. The hardest part is waiting for it to come out of the oven when your kitchen starts smelling amazing.

Tips for the Best Sheet-Pan Sausage with Peppers and Onions

After making this dish dozens of times (sometimes while half-asleep after a long day), I’ve learned a few tricks to make it absolutely perfect every time:

Speed it up with pre-cooked sausage: On really crazy nights, I’ll grab pre-cooked sausage links—they roast up in about half the time and still get that gorgeous caramelization.
Keep your cuts even: Slice the peppers and onions about 1/4-inch thick so everything cooks at the same rate. Nobody wants half-raw onions next to mushy peppers!
Give it space to breathe: If your pan looks crowded, the vegetables will steam instead of roast. Use two pans if needed—the crispy edges are worth it.
Taste as you go: Right before roasting, give your veggies a quick taste and adjust the salt or spices if needed. Trust your instincts!

These little tweaks make all the difference between good and “wow, can we have this again tomorrow?” good.

Serving Suggestions for Sheet-Pan Sausage and Peppers

This dish is delicious on its own, but here are my favorite ways to round out the meal:

Crusty bread: Perfect for soaking up all those flavorful juices—I always grab a baguette on my way home when making this.
Simple salad: A crisp green salad cuts through the richness beautifully. My go-to is just mixed greens with lemon vinaigrette.
Creamy polenta: The soft texture makes the perfect bed for those caramelized veggies and juicy sausages.

Honestly, sometimes we just eat it straight off the pan with forks—no shame in that!

Storage and Reheating Instructions

Leftovers? No problem! Store any extra sheet-pan sausage with peppers and onions in an airtight container in the fridge—it’ll stay delicious for up to 3 days. When you’re ready to eat, reheat it in a 350°F oven for about 10 minutes or toss everything in a skillet over medium heat until warmed through. The oven method keeps everything crispy, while the skillet gives you more control. Just avoid the microwave unless you’re in a real pinch—it makes the sausages rubbery and the veggies soggy. Trust me, a little extra effort makes all the difference!

Sheet-Pan Sausage with Peppers and Onions Nutritional Information

Just a quick note—the nutritional info for this dish will vary depending on the specific sausage and veggies you use. Different brands of Italian sausage, oil amounts, or vegetable sizes can change the numbers. What I can tell you is that it’s a balanced meal with protein from the sausage and plenty of vitamins from those colorful peppers!

Frequently Asked Questions

Over the years, I’ve gotten tons of questions about this sheet-pan sausage recipe—here are the ones that come up most often:

Can I add other vegetables? Absolutely! I love tossing in sliced zucchini, mushrooms, or even small potatoes (just cut them thin so they cook through). The more colorful the pan, the better—just keep everything roughly the same thickness.

Will chicken sausage work? Yes! I use chicken sausage all the time when I want something lighter. Just watch the cooking time since it tends to dry out faster than pork sausage.

How do I know when the sausage is done? The sausages should be golden brown and register 160°F internally. If you don’t have a thermometer, make a small cut—no pink should be visible inside.

How can I make this spicier? Easy! Use hot Italian sausage, add red pepper flakes to the veggies, or serve with spicy mustard or chili oil on the side.

Can I prep this ahead? You can chop the veggies in advance, but I don’t recommend assembling until right before roasting—otherwise the salt draws out too much moisture.
