I made this on a whim one night when the fridge needed clearing out, and it instantly became a family staple.
Sheet pan dinners saved me during the busiest seasons of parenting. I remember standing in the kitchen one evening, staring at a sweet potato, half a bag of Brussels sprouts, and a pack of bratwurst with zero inspiration. I threw it all on a pan, seasoned it with an onion soup mix I had in the pantry, and popped it in the oven. Thirty minutes later, my family was scraping the pan clean. This one pan sausage and veggies recipe is that simple, that colorful, and that satisfying. The lemon aioli adds a bright, garlicky finish that keeps everyone coming back for more. Make it your own!

Ingredients for One Pan Sausage and Veggies
After making this sheet pan dinner more times than I can count, I’ve learned a few things about what makes it really shine. I always use fresh Brussels sprouts over frozen — they caramelize beautifully in the oven and hold up much better. For the sausage, bratwurst is my go-to, but any pre-cooked or raw sausage you love works here.
- 1 pound Brussels sprouts (trimmed and halved if large)
- 1 large sweet potato (chopped into 1 to 2 inch pieces)
- 1/2 red bell pepper (sliced) — I recommend using a fresh, firm pepper for the best texture and color
- 1/2 yellow bell pepper (sliced)
- 1/2 red onion (chopped into chunks)
- 3 to 4 cloves garlic (smashed and left whole) — In my experience, leaving them whole gives a sweeter, more mellow garlic flavor
- 1 pound bratwurst sausages (left whole)
- 1/4 to 1/3 cup olive oil — My preference is a good everyday olive oil, nothing too fancy
- 1 (1 oz) package onion soup mix — Pro tip: Lipton is the classic, but any brand works great
- Fresh parsley to garnish (optional)
For the Lemon Aioli
- 1 cup mayonnaise
- 3 tablespoons lemon juice (about 1 small lemon)
- 3/4 teaspoon kosher salt
- 1 to 2 cloves garlic (smashed and minced) — I usually start with one clove and taste before adding more
- Cracked black pepper to taste
Step-by-Step Instructions
In my experience, the key to getting perfectly roasted veggies is making sure everything is spread out in a single layer with space between pieces. Crowded pans steam instead of roast, and you lose all that gorgeous caramelization.
Step 1: Preheat your oven to 400 degrees F. Line a large rimmed baking sheet with foil for easy cleanup.
Step 2: Prep your vegetables. Trim the Brussels sprouts, remove any yellow outer leaves, and halve any large ones. Chop the sweet potato into 1 to 2 inch pieces. Slice the bell peppers and chop the red onion into chunks. Smash the garlic cloves with the flat side of your knife but do not mince them — you want them whole.
Step 3: Add all the vegetables and garlic to the baking sheet. Nestle the bratwurst sausages right on top of the vegetables.
Step 4: Drizzle everything with 1/4 cup olive oil, then sprinkle the entire packet of onion soup mix evenly over the top. Use your hands to toss and coat everything well. If the veggies look dry, drizzle a little extra olive oil. Spread everything into a single layer with the sausages resting on top — this lets the fat from the sausage drip down and flavor the vegetables as they roast.
Step 5: Bake at 400 degrees F for 30 minutes. Flip the sausages halfway through if you want a crispier exterior on both sides.
Step 6: While everything roasts, make the lemon aioli. In a small bowl, stir together the mayonnaise, lemon juice, kosher salt, and one minced garlic clove. Add a few grinds of black pepper, taste, and adjust garlic or lemon as needed. Refrigerate until ready to serve.
Step 7: Serve the roasted sausage and veggies straight from the pan, with the lemon aioli on the side for dipping or drizzling. Pairs beautifully over hot rice or buttered noodles.
Perfect Pairings for One Pan Sausage and Veggies
The smoky, savory flavors of this sheet pan meal pair best with sides that are simple, starchy, or fresh. Here are some favorites that round out the meal beautifully:
Fluffy White Rice: A scoop of hot steamed rice soaks up all the roasting juices and balances the bold seasoning from the onion soup mix. It stretches the meal further for bigger families too.
Buttered Egg Noodles: Toss cooked egg noodles with a little butter and parsley and serve the sausage and veggies right on top. Comfort food at its best.
Crispy Oven Roasted Cauliflower: If you want to keep it low-carb and veggie-forward, roasted cauliflower makes a fantastic companion with a similar oven temperature and roasting time.
Garlic Roasted Vegetables: Double down on the vegetable goodness with a side of garlicky roasted veggies. Great for feeding a crowd or meal prepping alongside this dish.
Baked Garlic Parmesan Potato Wedges: Crispy, cheesy potato wedges are a crowd-pleasing side that pairs naturally with bratwurst and the tangy lemon aioli for dipping.
Sausage Veggie Skillet Bowl: If you love this flavor combo, this skillet version is another weeknight winner worth bookmarking for your rotation.
One Pan Honey Garlic Kielbasa and Veggies: A sister recipe that uses a similar one-pan method with a sweet and savory honey garlic twist — perfect for when you want to mix things up.
Storage and Serving Tips
Leftovers keep well in an airtight container in the refrigerator for up to 4 days. The flavors actually deepen overnight, making this a great recipe for meal prep. Store the lemon aioli separately in a small jar or container — it stays fresh in the fridge for up to one week and is wonderful on sandwiches or wraps.
To reheat, I recommend spreading the sausage and veggies on a baking sheet and warming them in a 375 degree F oven for about 10 minutes. This brings back the crispy edges far better than the microwave. A quick toss in a skillet over medium heat works well too.
Pro tip: The next morning, reheat a portion of the veggies in a skillet and top with a fried egg for an easy high-protein breakfast. It is genuinely one of the best ways to use leftovers, and my family loves it just as much the second time around.

With minimal prep, one pan to wash, and a sauce that comes together in minutes, this meal delivers big flavor with very little effort.
