Since I did all of the great recipes for you for Valentine’s Day, before Valentine’s Day, I had to come up with something fun for my Valentine!

I have had this recipe idea on my schedule since last winter, but haven’t been able to locate Romanesco, until just recently! So without further ado, here is my version of White Lasagna!

What is White Lasagna

White Lasagna is simply lasagna that is made without tomato sauce, or Bolognese sauce. Traditional, Italian lasagna combines a bechamel, or white sauce with a bolognese. The white sauce thickens up the tomato sauce, to make it creamy and delicious!

This White Lasagna is made with a Parmesam bechamel and with ricotta, so it is super rich!

What is Romanesco?

Romanesco is a cruciferous vegetable that has a very long history in Italy. It was very common even in the 16th century!

Romanesco is also known as Romanesco broccoli, or Romanesco cauliflower. It has a flavor that is reminiscent of cauliflower, but with a more subtle flavor!

Romanesco is also a gorgeous vegetable, high in vitamins C and K. It is known as a fractal. It’s buds are arranged in an algorithmic spiral, following the Fibonacci series. (Think of the spirals on a snails’ shell).

Romanesco is available in our area, usually in the late Fall and early Winter, but I have not been able to find any this year until recently. We found it several years ago and are truly enamored with it’s goodness!

There are quite a few steps to making this White Lasagna, but it is by no means difficult!

The other thing, every pot and pan and utensil will be dirty by the time this bad boy is in the oven! 😂 (well, not quite, but almost, and so worth it!) Next time you need a special dish to impress, this dish will certainly do that!

Can White Lasagna be frozen?

White lasagna freezes quite well, before baking, for 3 or 4 months, if it is well wrapped. Allow the lasagna to thaw in freezer for at least 2-3 days. Then bake as usual. (may take an additional 30 minutes or so to cook.)

Individual pieces of lasagna can be frozen after they are cooked. Thaw in the refrigerator and then microwave, or bake to reheat.

Cover lasagna with foil if the cheese on top is getting too browned.
Can be made 1-2 days ahead. Refrigerate. Allow the pan to come to room temperature for at least 30-45 minutes, before baking. Bake at 300°F for 30 minutes. Then increase oven temperature to 350°F. Cook until hot and bubbly.
If lasagna is covered, don’t let the foil touch the top of the cheese. It will stick to foil.
