How To Make Pierogi Casserole

1. Cook prosciutto: Preheat oven to 375°F and grease a baking dish with cooking spray. Cook the prosciutto in a skillet over medium-high heat for 2 minutes. Remove the prosciutto from the skillet and set aside. 

2. Cook garlic and onion: In the same skillet, saute onion until tender. Add the garlic and cook for 30 seconds more until fragrant. Remove the onions and garlic and set aside.

3. Cook pierogies: Add some cooking spray to the same skillet and cook the pierogies until golden brown on each side. If you're using frozen pierogies, make sure to thaw them first.

4. Assemble the casserole: Add the onions, garlic, and prosciutto back to the skillet and stir to combine everything with the pierogies. Add half of the pierogi mixture to a glass baking dish. Pour half the alfredo sauce on top and add half the shredded cheddar cheese. Repeat the layers until you've used all of the ingredients.

5. Bake and serve: Bake the casserole for 15 minutes or until the cheese is melted and golden brown. Serve warm, and enjoy!

Tips To Make The Best Recipe

• Mix cream cheese and alfredo sauce for a thicker sauce.
• Swap the alfredo sauce with cream cheese for a more decadent casserole.
• Instead of prosciutto, use bacon bits, cubed chicken, sliced Italian sausage, or turkey sausage.
• Use other shredded cheese like colby jack cheese, mozzarella cheese, or even pepper jack cheese for a little spice instead of shredded cheddar cheese.
• Serve the casserole with green onions on top and sour cream for dipping.

How To Store Pierogi Casserole

Reheating: Put the leftovers back in a casserole dish with a splash of chicken broth and heat in the oven at 350°F for about 10 minutes or until warmed through. Thaw the frozen casserole in the fridge overnight or add more reheating time.
