The way I would describe this Pierogi and Sausage Casserole is comfort food meets easy weeknight dinner.

Nothing beats a creamy, cheesy, comforting casserole but sometimes those casserole recipes can be time consuming or require a lot of prep work. The beauty of this casserole recipes is that it uses easy ingredients like frozen pierogis and jarred alfredo sauce.

Ingredients You'll Need

Measurements and exact information will be found in the printable recipe card at bottom of page.

Frozen Pierogi - There are many varieties to choose. I typically go for a simple potato and cheese and potato cheese and chive variety.
Ground Sausage - You can use mild sweet Italian or a spicy one. I also like to use a combo of both. If you can't find ground sausage, simply buy links and remove the casing.
Onions - Sweet yellow is what I use but I imagine any yellow or white onion will work well.
Alfredo Sauce - This is one of the rare occasions I use a jarred Alfredo. If you prefer to whip up a homemade alfredo, go for it.
Shredded Cheese - I like to use a cheddar-jack blend but any shredded cheddar or cheddar blend will work well.

Serving Suggestions

Casseroles like this tend to be hearty enough that they don't need a side dish.

You can add vegetables (green beans, peas or spinach) straight to the casserole if you'd like.

A side salad is what I prefer to eat alongside my casseroles. A simple green salad makes it feel a bit lighter.

Recipe Tip: If you have a large, oven-safe skillet, you can turn this into a one pot meal by layering everything right in the skillet.
