Well, maybe I should say a “brown out” since I’m a brunette.
When I made this recipe originally it was fantastic and we both loved it. There was one minor glitch however. When I decided to make this for dinner, the store didn’t have gruyere. (Big FAIL to you Mr. Grocery Store.) I was NOT in the mood to try another store, so I went to the deli and asked them to slice me the amount I needed. I found out later that gruyere from the deli doesn’t melt all that nicely. So instead of a nice cheesy, melty layer of gruyere…this had little thin sticks of gruyere. Brent said he liked it like this, but I was bummed for several reasons and even though I kept the pictures, I never posted it.
I decided to make it again since Easter is this weekend, and I think it would be an absolutely fantastic way to use up leftover ham. I made a few adjustments from my first attempt and I think it was for the better. This recipe has ham, asparagus, gruyere cheese, caramelized onions, and a Dijon béchamel sauce. It is the perfect storm of yummy goodness.

How to do it:
1 – In a medium sauté pan add 2 tablespoons of butter and diced onion. Sauté over medium low heat, keeping pan covered when not stirring occasionally. Cook until onions are caramelized, about 25 minutes. Click here for more detailed instructions on caramelizing onions.
2- While onions are cooking, take asparagus spears and trim the ends. (To find out where to trim, take a few and “snap” them by bending. They will naturally break where you will want to cut.) Next slice them thin and on a bias. Set aside.
