Ingredients Equipment Method Notes

Ingredients
  

  • 1 pound smoked sausage sliced
  • 2 large yellow onions sliced thin
  • 2 cloves garlic minced
  • 16 oz pierogi-style dough/uncooked pierogi could be frozen or homemade
  • cup shredded cheddar cheese optional for extra cheesiness
  • 2 tablespoons butter for sautéing

Equipment

  • Skillet
  • 8x8-inch Baking Dish

Method
 

  1. Heat a skillet over medium heat and add butter. Once melted, add sliced sausage and cook until browned and slightly crispy, about 5-7 minutes, filling the kitchen with savory aromas.

  2. Add sliced onions and cook, stirring occasionally, until they become soft, golden, and fragrant, about 8 minutes.

  3. Stir in the minced garlic and cook for another minute until fragrant, combining all flavors.
    2 cloves garlic
  4. Remove the sausage mixture from the heat and spread evenly in the bottom of the prepared baking dish.
  5. Arrange the uncooked pierogi evenly over the sausage and onion mixture, pressing down slightly to nestle them into the filling.

  6. Sprinkle shredded cheddar cheese over the top of the pierogi layer for added richness.

  7. Cover the dish tightly with foil and bake in a preheated oven at 375°F (190°C) for 35-40 minutes, until the pierogi are tender and bubbling.
  8. Remove the foil and switch the oven to broil for 2-3 minutes to crisp up the top edges, listening for a slight crackle as it browns to perfection.
  9. Take the casserole out of the oven, let it rest for a few minutes, and then serve hot, topped with a dollop of sour cream for extra creamy contrast.

Notes

Feel free to add your favorite herbs or a splash of paprika for extra flavor. Using homemade pierogi dough enhances authenticity, but store-bought works perfectly for convenience.
