In a medium mixing bowl, whisk together sour cream, hot mustard, eggs, dill and 1 cup of cheddar cheese (reserve ½ cup cheddar cheese). Mix thoroughly.

Cook in preheated oven for 45-55 minutes or until egg is fluffy and no longer runny.
Return to oven, turn up to broil (500 degrees F) for 1-2 minutes longer until cheese bubbles and browns slightly. Watch it carefully, as light/low fat cheese can burn very quickly.

Notes
Expert Tips:
Defrost the Pierogies Properly: Ensure the frozen pierogies are fully defrosted before using them in the casserole. This prevents excess moisture and ensures even cooking.
Chop Ingredients Ahead of Time: To save time in the morning, chop onions, cook the bacon, and drain the sauerkraut the night before. Store them in airtight containers in the fridge.
Use Sharp Cheddar for the Best Flavor: Old/sharp cheddar cheese enhances the taste of the casserole more than mild cheddar.
Evenly Distribute Ingredients: Spread out the pierogies, onions, bacon bits, and sauerkraut evenly in the casserole dish to ensure every bite has a balanced mix of flavors.
Don’t Overmix the Egg Mixture: Whisk the eggs, sour cream, mustard, and cheese just until combined. Overmixing can create a dense texture rather than a light, fluffy one.
Broil for a Crispy Finish: After baking, broil the casserole for 1–2 minutes to get a golden-brown, bubbly cheese topping. Watch it closely to avoid burning.
Storage:Store this breakfast perogy casserole in an airtight container for up to 3 days.These ingredients don't stand up well to freezing.
