What is a Pierogi?

Pierogi (which is both singular and plural, by the way!) are Polish dumplings made with a soft dough and filling of your preference. They are filled with both savory and sweet ingredients, with the most common being mashed potatoes and cheese. You can also add meat, vegetables, mushrooms, sauerkraut, etc. They are then boiled in water and pan-fried in butter.

This pierogi lasagna takes some of those elements and turns it into a fantastic casserole. It’s much easier to make and still super delish.

Ingredients Needed

Here’s what you’ll need to make this mashed potato casserole.
(Scroll below to the printable recipe card for details and measurements.)

• Mashed potatoes – You’ll need mashed potatoes with butter and milk added, as if you were serving the mashed potatoes as a side. They should be warmed when added to the casserole.
• Cottage cheese – Use 4% cottage cheese for the best texture. You can also use ricotta cheese, if preferred.
• Cheddar cheese – Shredded cheddar cheese is mixed in with the mashed potatoes and added to the top of the casserole.
• Lasagna noodles – Cook and drain the noodles before beginning the casserole.
• Butter – Unsalted or salted will work here. Cube the butter for easier melting.
• Sweet onion – These are sautéed and add a subtle sweet flavor to the cottage cheese layer.
• Egg – Acts as a binder to help hold the filling together.
• Seasonings – Garlic powder, onion powder, salt, and pepper.
• Scallions – To garnish the casserole at the end.

Easy Add-Ins

Like pierogi dumplings themselves, there are so many possibilities when making this pierogi casserole. If you have a favorite pierogi flavor, you can easily transform it into this casserole by mixing the ingredients in with the mashed potatoes. Here are a few ideas:

• Crispy crumbled bacon
• Sliced, cooked mushrooms
• Sauerkraut (well-drained)
• Ground beef (cooked and drain)
• Sausage (cooked ground Italian sausage)
• Scallions or chives (mixed into the potatoes instead of just as a garnish)

Tips for Success

This casserole is already super simple to make, but here are a few tips to make it even easier.

• Warm the mashed potatoes first. Warm mashed potatoes are much easier to mix and spread then mashed potatoes straight from the fridge. Add a splash of milk if needed to make them softer.
• Do not use no-boil noodles. This mashed potato casserole doesn’t work with no-boil noodles. You need to buy regular lasagna noodles and cook them before building the casserole.
• Use freshly shredded cheddar. Be sure to use a good quality brand of cheddar cheese and to shred it yourself instead of buying it pre-shredded. It will melt better and give the lasagna a much better flavor.
• Allow to sit before cutting. If you try to cut the pierogi casserole as soon as it comes out of the oven, you will end up with a mess. Allowing it to sit for 10-15 minutes will give the ingredients time to solidify.

Serving Suggestions

Just as you might serve pierogi dumplings with a dollop of sour cream and some diced scallions, this casserole version is no different. Those two additions really finish off the dish.

Since this casserole is on the heavier side, it pairs well with a simple side salad and/or some roasted vegetables. Roasted carrots, roasted asparagus and roasted broccoli are personal favorites.

How to Store & Reheat Leftovers

• Make Ahead. This pierogi casserole can be prepared up to a day in advance. Prepare as directed then cover with foil and refrigerate. You will need to add 5 to 10 minutes to the bake time when baking it directly from the fridge.
• How to store leftovers. Leftover pierogi casserole can be stored in the fridge for up to 4 days. Cover the pan with foil or transfer to an airtight container. It does not freeze well.
• How to reheat leftovers. Leftovers can be reheated in the oven or the microwave, until just warmed through.
