Ingredients

Scale

Main Ingredients

  • 24 oz frozen potato and cheese pierogis
  • 1 cup sour cream
  • 1 cup shredded cheddar cheese (or cheese blend), plus extra for topping
  • 1/2 cup heavy cream or milk
  • 3/4 cup sautéed onions (about 1 medium onion)
  • 2 tablespoons butter
  • 1/2 teaspoon garlic powder
  • Salt and pepper to taste

Optional Ingredients & Garnishes

  • Fresh parsley or chives, chopped (for garnish)
  • Cooked shredded chicken (optional protein addition)
  • Sautéed mushrooms, spinach, or bell peppers (optional vegetable boost)
  • Diced jalapeños or cayenne pepper (for spicy twist)
  • Alternative cheeses: mozzarella or pepper jack (for flavor variation)
  • Dairy-free alternatives: coconut cream and dairy-free cheese (for dairy-free version)

Instructions

  1. Prepare the Onions: Melt butter in a skillet over medium heat and sauté the onions until golden brown and sweet, about 8-10 minutes, to enhance their flavor and add depth to the casserole.
  2. Layer the Pierogis: Place a layer of frozen pierogis directly at the bottom of your crockpot. There is no need to thaw them beforehand, which saves time and preserves their texture during cooking.
  3. Mix the Creamy Sauce: In a separate bowl, combine the sour cream, heavy cream (or milk), shredded cheese, garlic powder, salt, and pepper. Stir until the mixture is smooth and well blended.
  4. Assemble the Casserole: Pour half of the creamy sauce over the first layer of pierogis, then evenly sprinkle half of the sautéed onions on top. Repeat with the remaining pierogis, sauce, and onions to create layered flavors.
  5. Cook Low and Slow: Cover the crockpot and cook on low for 3 to 4 hours, allowing the pierogis to soften and absorb the creamy sauce without becoming mushy.
  6. Finish with Extra Cheese: In the last 15 minutes of cooking, sprinkle additional shredded cheese on top to melt and create a delightful, bubbly finish.

Notes

  • Use frozen pierogis to maintain texture and reduce prep time.
  • Sauté onions first to bring out their sweetness and complement the creamy sauce.
  • Do not overcook; begin checking for doneness around 3 hours to prevent pierogis from becoming mushy.
  • Choosing sharp cheddar cheese offers bold flavor, while mozzarella provides ideal meltiness and stretch.
  • If sauce appears too thin after cooking, thicken by stirring in 1 teaspoon cornstarch dissolved in cold water, then cook for an additional 15 minutes.
  • Fresh pierogis can be used but require shorter cooking times, so adjust accordingly.
  • Traditional pierogis contain gluten; seek gluten-free versions for gluten-sensitive diets.
  • Vegan adaptations can be made by using vegan sour cream, dairy-free cheese, and plant-based butter.
  • For extra protein, add cooked chicken, bacon, or mushrooms.
  • If no crockpot is available, bake covered at 350°F (175°C) for 45 minutes, then uncovered for 10-15 minutes to brown the top.
