Ingredients

Scale

Base Ingredients

  • 2 lb. potato pierogi (or your favorite frozen pierogi flavor), divided
  • 2 Tbsp. extra-virgin olive oil, divided

Cheese & Cream

  • 1 (10.5-oz.) can cheddar cheese soup or cream of mushroom soup
  • 8 oz. cheddar, shredded, divided
  • 15 oz. farmer’s cheese or ricotta, divided

Vegetables & Sausage

  • 1 (5-oz.) pkg. fresh or frozen spinach, thawed, drained, divided
  • 1/2 medium yellow onion, finely chopped or thinly sliced, divided
  • 1 (12-oz.) pkg. smoked kielbasa sausage, thinly sliced, divided

Seasoning & Garnish

  • Kosher salt, to taste
  • Thinly sliced scallions, for serving

Instructions

  1. Preheat Oven and Prepare Dish: Preheat your oven to 375°F (190°C). Grease a 13″ x 9″ or 11″ x 7″ baking dish with 1 tablespoon of olive oil to prevent sticking and enhance flavor. Then, arrange 12 pierogi in a single layer to completely cover the bottom of the dish.
  2. Mix Cheese Soup and Assemble First Layer: In a medium bowl, combine the cheddar cheese soup (or cream of mushroom soup) with three-quarters of the shredded cheddar cheese, mixing well. Pour half of this soup mixture evenly over the pierogi layer. Next, crumble half of the farmer’s cheese over the pierogi and sprinkle with half of the spinach, half of the chopped onion, and half of the sliced kielbasa sausage. Season with kosher salt to taste.
  3. Add Second Layer: Repeat the layering process with the remaining pierogi, pour the remaining half of the soup mixture, crumble the rest of the farmer’s cheese, and scatter the remaining spinach, onion, and kielbasa evenly over the top. Sprinkle with the remaining one-quarter of shredded cheddar cheese and season again with kosher salt. Drizzle the remaining 1 tablespoon of olive oil over the top of the casserole.
  4. Bake the Casserole: Place the assembled casserole in the preheated oven and bake for about 45 minutes or until the casserole is heated through, bubbling, and the cheese is melted and incorporated.
  5. Broil for a Crispy Top and Serve: Switch your oven to the broiler setting. Broil the casserole, watching very closely, until the top becomes crispy and lightly browned, approximately 3 minutes. Remove from oven, garnish with thinly sliced scallions, and serve warm.

Notes

  • You can substitute the potato pierogi with cheese or sauerkraut pierogi depending on your preference.
  • Use fresh spinach for a brighter flavor, or frozen spinach to keep it budget-friendly and available year-round.
  • Be sure to watch the casserole closely during broiling to avoid burning the top.
  • Leftovers can be refrigerated up to 3 days and reheated in the oven or microwave.
  • Adding extra smoked kielbasa or using spicy sausage can add more kick to the dish.
