Cheesy Pierogie and Mushroom Casserole

Follow our step-by-step guide on how to make Cheesy Pierogie and Mushroom Casserole.

1. Step 1

   Start by preheating your oven to a cozy 375°F (190°C).

2. Step 2

   While the oven warms up, grab a lasagna-sized casserole dish and give the bottom and sides a light spray with cooking spray to prevent sticking.

3. Step 3

   Now, let’s bring some flavor to life! In a large skillet, cook the chopped bacon over medium-high heat, stirring occasionally until it turns a beautiful golden brown, which should take about 5 to 10 minutes.

4. Step 4

   Once it’s perfectly crispy, transfer the bacon to a paper towel-lined plate to soak up any excess grease.

5. Step 5

   Next, in that same skillet, toss in the diced onions into the remaining bacon grease.

6. Step 6

   Sauté them until they’re golden and fragrant, which will take another 5 to 10 minutes.

7. Step 7

   Once they’re ready, join them on the plate with the bacon and drain any leftover grease from the skillet.

8. Step 8

   Now, let’s add some earthy goodness! Melt a bit of butter in the skillet over medium-high heat, then add the sliced mushrooms.

9. Step 9

   Sauté these until they’re golden and their moisture has evaporated, which should take about 5 to 10 minutes.

10. Step 10

    Now it’s time to build our delicious layers! Start by placing a single layer of frozen pierogies at the bottom of your prepared casserole dish.

11. Step 11

    Spread one can of condensed cream of mushroom soup evenly over the pierogies, creating a creamy base.

12. Step 12

    Next, sprinkle the cooked bacon, golden onions, and sautéed mushrooms on top, adding a burst of flavor to each bite.

13. Step 13

    For the second layer, add another round of frozen pierogies, followed by the remaining can of cream of mushroom soup.

14. Step 14

    To finish it off, generously sprinkle shredded Cheddar cheese on top, because who doesn’t love a cheesy finish? Cover your casserole dish with aluminum foil and pop it into the preheated oven for 45 minutes.

15. Step 15

    After that, carefully remove the foil and let it bake for an additional 10 to 15 minutes, or until the casserole is golden and the cheese is bubbling with excitement.

16. Step 16

    The aroma wafting through your kitchen will be irresistible! Once it’s done, let it cool for a few moments before serving.

17. Step 17

    Enjoy this comforting dish that’s sure to warm your heart and satisfy your taste buds!.
