Karlynn’s Recipe Notes

  • Skill Level: This recipe is easy to make, just toss everything into your slow cooker and let it go!
  • Total Time: You can have dinner ready in 2 hours and 30 minutes; but since you don’t have to babysit this dish, you’ll be free to take care of other things around the house!
  • Variations: Even though this recipe specifies a bacon, potato, cheese and onion filling, there’s nothing keeping you from changing it up! You could add different types of meat, such as sliced kielbasa, braised beef or lamb, along with cabbage or sauerkraut; go for a more Greek flavor by using spinach and feta; or even make a dessert pierogi casserole by filling it with cherries or strawberries! Play around and make something that works best for you!
  • Tools For This Recipe: You will need a slow cooker or crockpot and a cheese grater to make this recipe

What You’ll Need for Ingredients

Lasagna Noodles: This recipe calls for uncooked lasagna noodles, the kind you find in the pasta aisle for making Italian-style lasagna. You need to be careful, though, because right next to the normal lasagna noodles are often the supposedly “more convenient” no-cook lasagna noodles. Do not, under any circumstances, buy the “no-cook” variety for this recipe! They’re not only pre-cooked and then dried for convenience, but they’re made of slightly different ingredients. If you use the no-cook variety in this recipe, your casserole will turn out mushy, mealy, and more or less ruined.

Cheddar Cheese: Reach for an aged/sharp cheddar for this recipe, as the tanginess will help cut through the rich flavors of the other ingredients!

Lasagna noodles, diced potatoes, shredded cheddar, ricotta, chopped onion, bacon slices, butter, milk, granulated onion, salt, and pepper are arranged on a marble surface with a kitchen towel in the background.

Potatoes: Reach for your everyday baking potatoes for this recipe! The best options are low moisture, starchy varieties like Russets (also called Idaho potatoes) or if you’re in the UK, King Edward or Maris Piper potatoes. Thin-skinned, waxier potatoes don’t do as good a job as absorbing fat and butter.

Bacon: This recipe calls for a pound of pre-cooked bacon. You can either follow the package instructions for cooking it in the oven, or use a package of pre-cooked bacon for added convenience!

How To Make Crockpot Lazy Pierogi Casserole

This is a quick overview of the recipe. The full list of ingredients & complete step-by-step instructions are in the recipe card below.

  1. Mash boiled potatoes with the butter, salt, pepper and milk, until smooth.
  2. Mix the cheddar, ricotta, and onion powder into your mashed potato mixture.
  3. Fry diced onions in a pan with a tablespoon of butter until soft. Pre-cook your bacon in the oven, then cut it into smaller pieces with a knife or kitchen shears.
  4. Layer 3 cooked lasagna noodles into the bottom of your crockpot, then spread a cup of ricotta cheese over them. Spread 1/3 of your potato cheese mixture on top of the ricotta.
  5. Spread 1/3 of your bacon and 1/3 of your onions on top of the potatoes.
  6. Continue layering cooked lasagna noodles, ricotta cheese, potato mixture, bacon, and onions. For the final layer, you will not need any ricotta, just place the last three noodles on top, then potatoes, then bacon and onions. Cook in your crockpot on low for 2 hours.

Karlynn’s Tips and Tricks for the Perfect Crockpot Lazy Pierogi Casserole

  • Melt My Heart: It might be tempting to use pre-shredded cheese for simple recipes like this one, but it’s better to grate your own! Pre-shredded cheeses have anti-caking agents added to keep the shreds from clumping together in the bag. While this doesn’t really impact how they act when you bake them as a topping, it can make them melt irregularly, leading to slightly unpleasant lumps.
  • Creamy Goodness: This recipe calls for Ricotta cheese because of its smooth, creamy texture, but if Ricotta is difficult to find or too pricy for your pocketbook, you can substitute it for an equivalent amount of drained cottage cheese! You’ll get the same creamy taste, but the curds will be a bit larger and more noticeable in the final dish.

Storage Instructions

Refrigerator: Leftovers can be stored in an airtight container in the fridge for up to 4 days. Leftovers reheat well in a moderate oven or 1 minute increments in the microwave.

Freezer: To freeze this casserole, make sure that it’s fully cooled before storing it in a freezer-safe, airtight container. It will keep in the deep freeze for up to 3 months! When you’re ready to eat it again, let it thaw in the fridge overnight and bake it in your oven at 350°F until warmed through. Sprinkle some extra cheddar cheese on top before baking if you want a little extra goodness!

    No Eastern European ancestors on either side of my family, but my hometown is fairly close to Chicago, so frozen pierogies are readily available at the supermarket (as are stuffed Italian pastas such as ravioli and tortellini). Could frozen pierogies be turned into a casserole instead?

  2. Linda says

    Just wondering what is so easy about this? Seems like a lot of steps to me.

  3. Rhonda says

    Holy cow!!!! Made this tonight and let me tell you…..yummmmmmmy!! It tasted like my grandma’s (Polish) pierogies!!! Thank you for sharing this recipe! It’s a keeper!!!5 stars

  4. Jeannine Parent says

    Even America’s Test Kitchen agreed that cottage cheese is by far tastier than bland ricotta. So also say the Ukrainians in my family. 😄
