Instructions
Preparation
Preheat your oven to 400°F (200°C) and line a large baking sheet with foil or parchment for easier cleanup.
Slice the kielbasa into 1/2-inch rounds and set aside.
In a large bowl, combine the frozen pierogies, sliced sausage, bell pepper strips, and sliced onion. Drizzle with olive oil and season with salt and pepper. Toss until evenly coated.
Cooking
Spread the mixture in a single layer on the prepared baking sheet, making sure to give each piece space to crisp.
Roast for 25–30 minutes, turning or stirring once halfway through, until the pierogies are golden-brown and the sausage is heated through.
Remove from the oven, taste and adjust seasoning. Garnish with chopped parsley if using, and serve immediately.
Notes
For extra crispy pierogies, finish under the broiler for 1-2 minutes. Serve straight from the pan or plate with sides like a green salad, sour cream, or steamed broccoli.
