It’s LASAGNA time!

I know what you are thinking. “Lasagna? I don’t have tiiiiiime for Lasagna”. I also don’t have time for lasagna, no one does,  and this one’s a pain in the you-know-what. That said, just make it. One time. That’s all I’m asking. Take a Sunday, and make the darned lasagna.  And when people ask you what you did all day, stand tall and tell them you made lasagna. With béchamel. Because Rivka said so. AND IT WAS WORTH IT.

This is a béchamel based lasagna, which means it uses a creamy, thickened milk-based sauce instead of the standard tomato-based. The béchamel recipe included here is based on a recipe from Deb over at Smitten Kitchen (one of my favorite food blogs, follow her), specifically this one, and she bases it on Ina Garten’s original béchamel which you can find here. I’ve adjusted the amount of nutmeg in this version, but it is otherwise consistent with the original.

Let me know what you think!
