Looks great! Maybe caramelize the onions first for extra extra flavor.
That’s a good idea. I will have to try that.
I put in 1/2 cup of chopped onions with 1 Tsb butter and cooked until translucent. Then I removed them, added more butter and flour for the roux. I will also try adding all the butter and the onions, cook until softened, and then add the flour and cook the roux for a few more minutes with the onions in there. Maybe that will darken them a bit.
Or I can cook the roux for longer and give it some more flavor with a blond roux as opposed to a white one. The fun part of cooking for me is the experimentation. I always fiddle with the recipe but never write it down and usually forget. Hehe.
