This is a delicious, decadent and luscious French "bread casserole" from "The Zuni Café Cookbook" that you will want to make again and again. It's a great use for stale bread and a very forgiving recipe, you can improvise with other greens and cheeses.
As with all panades, you may need a little more bread, or have some left over; same with the liquid, depending on the size and shape of your baking container. If you have more time, you can cook this at 250°F, for about 2 hours 45 minutes; the slower the bake, the more unctuous and mellow the results.
If you have leftovers, the Zuni Cafe's Chef Judy Rodgers instructs: Warm about 1 tablespoon extra-virgin olive oil in a nonstick skillet over medium heat. Slide in a scoop cold panade and press gently to make an 2-inch-thick patty. Fry gently to make a golden crust, about 3 minutes, then fry the other side. It's also great rewarmed in the microwave. It is actually not difficult to make; the instructions are just very detailed. You can skip the stovetop step and still get great results. Enjoy!
