I love that you can make this however you want with whatever veggies and meat you want. It's a one-pan meal that hits all the right notes with minimal cleanup.
Sheet Pan Kielbasa, Potatoes and Veggies
1 package (14-16oz) precooked sausage or kielbasa cut in half lengthwise and sliced into 1/2" half-moons
1 medium onion (red, white, whatever you have), cut into bite sized pieces
2 broccoli crowns, separated into florets
1 small head cauliflower, separated into florets
1/2 lb red potatoes, peeled and cut into small, bite-size pieces
3 tablespoons olive oil
1 tablespoon paprika
1 tablespoon onion powder
1/2 tablespoon garlic powder
1/2 tablespoon dried thyme
1 teaspoon kosher salt, or to taste
1/2 teaspoon freshly grated black pepper, or to taste
1 cup shredded cheddar cheese (or mozzarella, Monterey Jack, colby, whatever you want)
Preheat the oven to 450 and line a baking sheet with a couple sheets of aluminum foil.
Combine the sausage, onion, broccoli, cauliflower and potatoes in a large bowl. Season with the oil, paprika, onion and garlic powders, dried thyme, salt and pepper. Mix well. Dump onto the baking sheet and spread out in an even layer. Put sheet pan in the oven.
Roast for 25 minutes. Remove pan from the oven and test to make sure the potatoes are fully cooked (use the tip of a knife). If they aren't, put back in the oven for another 5-10 minutes. Once the potatoes are cooked through, top with the shredded cheddar cheese and put back in for another 5 minutes to melt the cheese.
