Sheet-Pan Kielbasa and Vegetables with Dijon Dressing
A simple one-pan dinner featuring roasted potatoes, sliced kielbasa sausage, red onions, and baby kale finished with a tangy Dijon mustard dressing. The potatoes develop crispy edges while the kale wilts perfectly, creating contrasting textures that complement the smoky sausage. Perfect for busy weeknight meals when you want something hearty and satisfying without multiple dishes to clean. The mustard dressing adds brightness that cuts through the richness of the butter and sausage.

FAQ
Can I use other types of sausage?
Yes, any pre-cooked sausage works well. Adjust cooking time if using raw sausage - add it earlier with potatoes.
What if I don't have baby kale?
Regular kale works but remove thick stems and massage leaves first. Spinach is another option but reduce cooking time.
How long will leftovers keep?
Store covered in refrigerator for up to 3 days. Reheat in 350°F oven for best texture.
