Sheet pan sausage and veggies comes together so quickly that it has become my go-to meal for busy weeknights. You just need one pan for all the chopping tossing and roasting. Everything caramelizes perfectly in the oven and cleanup is a breeze.
I first tossed this together on a night when I had no energy and almost no groceries but now it is a regular request from everyone in the house especially when the weather turns cool.
Ingredients
- Smoked kielbasa sausage: brings rich smoky flavor and a meaty bite Always look for sausage with natural casing for best snap
- Butternut squash: adds a naturally sweet contrast to the savory sausage Pick squash pieces that are deep orange for ripeness
- Bell peppers: bring a burst of color and gentle sweetness Use any combination of red yellow or orange peppers for more flavor depth
- Zucchini: roasts up tender and creamy Go for firm medium zucchini that feels heavy for its size
- Red onion: creates an aromatic base and caramelizes well Thick slices work best to avoid burning
- Olive oil: coats all the ingredients for even roasting Use a fruity extra virgin variety to enhance flavor
- Dried thyme: adds a woodsy note Check your thyme for green color which means freshness
- Smoked paprika: brings subtle smokiness and beautiful color Spanish smoked paprika is especially vibrant
- Garlic salt: delivers garlicky depth and balanced seasoning Choose one that smells pungent and fresh
- Ground black pepper: wakes up all the other flavors Freshly ground always gives the brightest kick
Step-by-Step Instructions
- Prep Butternut Squash:
- Quickly steam diced squash in the microwave for two minutes This softens it slightly so it will roast evenly with everything else Make sure not to overcook
- Chop and Combine Vegetables and Sausage:
- Cut all remaining veggies to similar sizes and slice sausage Place everything in a large mixing bowl so the oil and seasoning will coat well
- Season Thoroughly:
- Drizzle olive oil over the bowl then sprinkle in thyme smoked paprika garlic salt and black pepper Toss carefully making sure each piece is coated on all sides with oil and seasonings For best results use your hands to mix gently
- Prepare Baking Sheet:
- Brush a baking sheet lightly with olive oil for added crispness You can line it with parchment for easier cleanup if you wish but it is not essential
- Spread and Roast:
- Pour the seasoned mixture onto the pan Spread evenly so nothing overlaps if possible Roast in a preheated 400 degree oven for about 25 minutes The veggies should be browned at the edges and tender while the sausage takes on a slight crisp

The sausage is always my favorite part because it gets crisp at the edges and juicy inside My kids love picking out the pieces of sweet caramelized squash and I always remember serving this dish after a chilly soccer practice everyone crowding around the oven
Storage Tips
Leftovers store beautifully in an airtight container in the fridge for up to four days Reheat in the oven or a skillet to maintain crispness Avoid microwaving for best texture Everything can be made ahead for meal prep and packed into lunchboxes
Ingredient Substitutions
You can swap sweet potato for the butternut squash if that is what you have Chicken apple sausage is also delicious if you prefer a lighter protein If you are missing any of the veggies try broccoli florets brussels sprouts or even chunks of carrot The seasoning is flexible too so feel free to add Italian herbs or a pinch of chili flakes for more heat
Serving Suggestions
Serve this dish over fluffy rice polenta or with roasted potatoes for a heartier meal Sometimes I top it all with a sprinkle of parmesan or a dollop of whole grain mustard For brunch leftovers work wrapped in a tortilla or tossed with scrambled eggs

Cultural Roots
Sheet pan dinners have a long history as an efficient way to feed a crowd with little effort Kielbasa sausage is a staple in Central and Eastern European kitchens and it lends both tradition and bold flavor to this modern dish Roasted vegetables have been celebrated for centuries as a way to maximize flavor with minimal seasoning
