How To Make oo-la-la onion casserole
-
Step 1In a large 3 qt. saucepan, saute' onion slices in melted butter over med-low heat, until they're golden yellow, but not browned. Note: This step takes time -- 20-30 min. Stir the onion often. Watch carefully the last few minutes to prevent scorching.
-
Step 2Meanwhile, with food release spray, prepare 4-8 single-serving baking dishes (such as oven-safe soup bowls, ramekins, oval casserole or au gratin dishes); use four for meal-size servings, or eight dishes for appetizer and sides.
-
Step 3In a small saucepan, stir together the soup, beef base, milk, soy sauce, and pepper until warm and blended. Turn off heat and let set until onions are ready.
-
Step 4Divide the onions evenly into your baking dishes.
-
Step 5Layer 2/3 of the shredded Swiss cheese over the cooked onion.
-
Step 6Pour the soup mixture over the cheese layer, and stir gently to combine.
-
Step 7Cover the tops with a slice/s of french-style bread.
-
Step 8Bake, uncovered, at 350* for 10-15 min, til heated through.
-
Step 9Remove from oven. Push bread slices into the onion and soup mixture. Top with remaining cheese, and return to oven for an additional 10-15 min, or until lightly browned and bubbly.
-
Step 10Turn off the oven and allow the casserole to rest in the oven for 10-15 min more. Remove from oven and serve immediately, with a light green salad, and a glass of favorite wine.
-
Step 11NOTE: 1) My family is gluten intolerant so I used slices of GF french-style bread, which worked perfectly. 2) You could bake this in a 3 qt. casserole dish, but it's not as pretty when you serve it. If you're going to use the large casserole dish I recommend breaking the bread into chunks, to make serving easier.
