Frequently Asked Questions

Can I use homemade pierogi instead of frozen?

Yes, homemade works wonderfully. Just make sure they are fully boiled before layering so they bake evenly and remain tender.

What other vegetables can I add?

Popular additions include spinach, peas, shredded carrots, cabbage, or leeks. Sauté or steam them before layering to prevent excess moisture.

Can I make this casserole ahead of time?

Absolutely. Assemble it up to 24 hours in advance, refrigerate covered, and bake when ready. You may need to add a few extra minutes of baking time.

How can I make the sauce thicker or thinner?

For thicker sauce, add more cream cheese or reduce broth. For thinner sauce, whisk in extra broth a tablespoon at a time until your desired consistency.
