By the seat of my pants
400 degree oven
2 or 3 onions, sliced about 1/2 inch thick, you can ring out or leave in a solid slice
dry bread crumbs (1/2-3/4 cup)
Parmesan cheese (same as above!)
salt and pepper
Cover the bottom of a large lidded pan with a thin layer of olive oil. Add onions, then season with salt and pepper. Sprinkle with a layer of dry bread crumbs, then the Parmesan cheese. Bake covered for 20 minutes, then remove cover and bake an additional 20-30 minutes or until golden and bubbling.
The onions may not be completely cook, they will be crisp tender. If you want completely cooked onions, bake for 30 minutes covered BEFORE adding the dry bread crumbs and cheese.
As always thanks so much for taking a moment to stop by.
