Zucchini is either feast or fathom. This year started with fathom and turned into feast! Caramelized Onion Zucchini Lasagna is a feast!!
This recipe is one of my oldest and one of my absolute favorites. Garden fresh zucchini, layered with caramelized onions, a creamy white sauce with a hint of nutmeg, and swiss cheese. Creamy and fresh.
How I came across this recipe is a bit of a story. Sitting in a Dr. office can be a test of patience. In pre-cell phone days, all you could do was look at the worn-out old magazines and wait.
As I sat in the lovely paper gown, they give you, trying not to move and either rip the gown or make the crumply sounds they make; I leafed through a magazine. I wish I could remember the magazine, but as I said, it was a long time ago — no cell phone pre-internet.
Even back then, I was always on the lookout for new and exciting recipes. This recipe caught my eye. I would have copied the recipe but no pen, no paper…ugh! What was a girl to do? As quietly as I could, I ripped the recipe out of the magazine. Horrified the whole time the Dr. would take that moment to appear. I do not condone this type of behavior, and it was the only time I ever did it. To this day, I feel slightly guilty about my actions.
Having said that, I’m so glad I have this recipe. It is delicious. Over the years, I have tweaked the original several times. The original calls for cooking the lasagna noodles, this recipe was pre-noncook noodles.
I have also swapped out the original parmesan cheese for swiss cheese. Swiss cheese to me is a better taste with the caramelized onions.
The zucchini was sauteed in the original, but I found that unnecessary. Zucchini and yellow squash can be combined to create beautiful color for the lasagna.
As we near the end of another gardening season and knowing you all have zucchini to use, try our Caramelized Onion Zucchini Lasagna, it is the perfect end of summer meal.Print
