Frequently Asked Questions

Can I use frozen spinach instead of fresh?

Absolutely! Just make sure to thaw and thoroughly drain the frozen spinach before using it. Squeeze out as much excess water as possible to prevent a soggy lasagna.

What’s the best substitute for béchamel sauce?

If you’re short on time, a good-quality Alfredo sauce can work in a pinch. However, homemade béchamel is worth the effort for its rich, velvety texture.

Can I make this lasagna ahead of time?

Yes! Assemble the lasagna, cover it tightly, and refrigerate for up to 24 hours before baking. You may need to add a few extra minutes to the baking time if it’s going straight from the fridge to the oven.

How do I store leftovers?

Leftovers can be kept in an airtight container in the fridge for up to 3 days. Reheat individual portions in the microwave or cover the dish with foil and warm it in the oven at 350°F until heated through.
