This is close to the recipe made.....add a splash of red wine (shh...I used grenadine), 3 TBS Worcestershire, 1 TBS Soy Sauce. I suggest sauteing the onions awhile and deglazing the pan a few times with some broth to get all the yummy goodness from them.
Sweet Onion Casserole -- or my cousin's recipe --2 large Vidalia onions sliced and separated. salt , pepper, 1 can cream of chicken soup (dilute it a little bit) mix all together to coat onions with soup. Cover and bake about 30 min or until onions are tender. Sprinkle heavily with parmesan cheese panko bread crumbs and ritz cracker crumbs. Bake until browned.
The Best Green Bean Casserole! You make your own cream of mushroom soup with portobello mushrooms and add sweet yellow onions and garlic. Then you stir in perfect fresh green beans and top it with crispy french fried onions!
