Ingredients

The ingredients are:
  • 3 onions (large sweet onions, Vidalia, FL sweet onions, etc), cut in half and sliced)
  • 1 leek, thin sliced (white and light green parts)
  • 1 garlic clove, minced
  • 8 slices french bread
  • 1 cup gruyere cheese, shredded (you can use all swiss, but I like the 2 different flavors - gruyere has a nice nutty flavor)
  • 1 cup swiss cheese, shredded
  • 1 (10 3/4 ounce) can Cream of Mushroom Soup (low sodium or 99% fat free)
  • 2/3 cup milk
  • 1 teaspoon soy sauce
  • 1 tablespoon fresh parsley, chopped
  • 1 teaspoon dried thyme
  • Salt to taste
  • Pepper to taste
  • 2 1/2 tablespoons butter
We recommend you get your ingredients ready before you start cooking. Once you're ready, here are the steps to making this delicious recipe

How to Make

  • Step 1: Onions ... Add the butter to a large saute pan and bring to medium-medium low heat. Add the onions, leeks, and garlic, and saute until tender, about 10 minutes. You don't want them to brown too much - so go slowly. Season with a pinch of both salt and pepper as they cook. Once the onions are cooked through, check for seasoning once again. Remember, you are adding the soup which can be salty, so go easy.

  • Step 2: Casserole ... Add the onion mixture to a shallow casserole dish, sprayed with a nonstick spray, and top with 2/3 cup of the cheeses.

  • Step 3: Sauce ... In a microwave safe dish or measuring cup; add, the soup, milk, soy sauce, and thyme; and heat for 1 minute on medium heat. You want it warmed up - NOT boiling. Pour over the onions and cheese and gently stir to combine. Season, again with a pinch of salt and pepper, and top with the bread slices. DO NOT push them down, just set them on top.

  • Step 4: Bake ... In a 350 degree oven, on the middle shelf, for 15 minutes. Remove from the oven, push the bread slices down, into the sauce, so they are covered. Then, top with the remaining cheese, and bake another 15 minutes; until the cheese is melted, and the casserole is bubbly and golden brown.

  • Step 5: Serve and ENJOY! ... Garnish with the fresh parsley. Fantastic to serve with grilled steak, chicken, or pork. It is delicious and rich; yet inexpensive, and easy to prepare. Makes a great potluck or BBQ dish too!
