Oil

💡 Expert Tips and Tricks

- Homemade Italian seasoning will give you more flavor than store bought.
- Allow 3 to 5 extra minutes of baking time at the end for a more caramelized finish.
❔ FAQs
This is a kind of Polish sausage that's made from ground pork and typically seasoned with black pepper, marjoram, and garlic. Kielbasa is usually smoked, which gives it a deeply savory and smoky quality that pairs well with the garlicky flavor.
Because kielbasa is smoked, most kinds you purchase will come pre-cooked. Baking the sausage will still give it a crispier and more flavorful finish, but you won't have to worry about undercooking.
This typically happens if the sheet pan is overcrowded, which will prevent the moisture of the veggies from properly escaping and evaporating. You may also need to add a bit more oil to ensure that the veggies get crispy and golden.

📝 Substitutions and Variations
- Yellow squash or broccoli can be used instead of the zucchini.
- Baby potatoes or sweet potatoes diced into small pieces are a great addition to this dish.
- For some cheesy flavor, sprinkle with Parmesan in the last few minutes of baking.
- Smoked sausage, chicken sausage, and turkey sausage can all be used instead of the kielbasa if you prefer.
Kristin's Kitchen Tip
Be sure to slice everything into evenly sized pieces. This will help all of the ingredients cook at the same rate so nothing ends up overdone or undercooked!
🥡 Storage and Reheating
Transfer leftovers to an airtight container and store in the fridge for 3 to 4 days.
You can reheat this roasted kielbasa and veggies in the microwave or in a skillet, or toss them in a small amount of oil and bake at 350. Another great option is to use leftovers in omelets or egg scrambles for breakfast. You may need to chop it up smaller for this.
⏳ Make Ahead Instructions
