This recipe for Lazy Slow Cooker Pierogi Casserole is one that is sure to stay a staple in your home for years. Not only are slow cooker casserole recipes like this completely delicious, they are also budget friendly and hassle-free.

This recipe is more authentic than some because it doesn't use pre-packaged pierogis. Instead you'll "build" your own casserole-style inside your slow cooker.

This recipe takes a little longer to prepare because it has separate elements to consider -- cooking the noodles, and boiling the potatoes for example -- but the end result is a creamy and comforting casserole that you'll be proud to serve and dying to eat.

Preparation Time30 min

Slow Cooker Time LOW2 hr



  • 9 uncooked lasagna noodles
  • 8 medium baking potatoes, peeled & cut into chunks
  • 1/4 cup milk
  • 1/4 cup butter
  • 2 cups mild or sharp cheddar cheese, shredded
  • 1 teaspoon kosher salt
  • 1 teaspoon black pepper
  • 2 medium onions
  • 1 tablespoon butter
  • 2 cups low fat ricotta cheese
  • 1 pound bacon


  1. Cook noodles following package directions. Drain and rinse. Place on a lightly greased baking sheet, cover with wax paper until ready to use.

  2. Preheat oven to 350 degrees F. Place bacon on parchment or foil lined baking sheet and bake until cooked but still soft about 15-20 minutes. Drain on paper towels, let cool. Cut into small pieces.

  3. Peel and cut potatoes, place in a pot of cold water, bring to a boil and cook until tender.

  4. Slice onions and saute with 1 tablespoon of butter until slightly caramelized.

  5. Drain potatoes and place in a large mixing bowl.

  6. Mash potatoes with the butter, milk, salt and pepper until smooth. Mix in the cheddar cheese.

  7. Grease a large crockpot.

  8. Place three lasagna noodles onto bottom of crockpot. Spread 1 cup ricotta on top of noodles.

  9. Spread 1/3 of the potato cheese mixture on top of the ricotta.

  10. Place another 3 noodles on top and repeat layer.

  11. Place the last 3 noodles on top, then potatoes, bacon, onions, no ricotta.

  12. Cover crockpot with lid and cook on LOW for 2 hours.

  13. Serve with sour cream.

Sounds much easier than making my own Pierogi, so I'd like to try this recipe. My crock pot is one of those old round ones, so this wouldn't work in mine. How can I adopt this recipe in order to bake it in a conventional oven?

Hi catlady6866, I would try baking this casserole in a 350 degree F oven for about 15-20 minutes. I hope that helps! - Natalie, Editor of AllFreeSlowCookerRecipes

Try breaking the lasagna noodles into smaller pieces BEFORE cooking them. They will conform to your smaller crockpot. The top layer is covered by potato so no one will notice

This looks so delicious! Can't wait to try it.

Pierogi in a casserole? I can't wait to try this recipe. It looks so easy to make, too!

This casserole sounds amazing!! I love mashed potatoes so much. Plus, it has cheese, bacon, and pasta, too?! What more could you ask for!

Did someone say potato lasagna made in heaven...There's nothing bad about this yummy cheesy goodness! I've only had the pre-made frozen version of pierogis a few times and had no clue they were made with pasta. The combination of cheddar and potatoes go so nice you know if this is the standard pierogi filling?

One word YUM! This was warm, comforting and tasty!

Such a comforting cold weather recipe! I'd probably use turkey kielbasa instead of bacon, and maybe even sneak in a few vegetables.
