Ingredients
rich and simple French onion soup method
Step: 1 Assemble all the ingredients, and melt the butter with olive oil over medium heat in an 8-quart stock pot. Then add the onions to the butter and continue stirring till tender and translucent. But do not brown the onions.
Step: 2 Now add the beef broth, sherry, and thyme. Season with salt and pepper. Let it gently boil for about 30 minutes.
Step: 3 For now, preheat the oven’s broiler.
Step: 4 Then ladle the soup into oven-safe serving bowls and put one slice of bread on top of each ( if you prefer so bread may be broken into pieces). Surface each slice of bread with a slice of provolone, 1/2 slice of diced Swiss, and 1 tablespoon of Parmesan cheese.
Step: 5 Set the bowls on a cookie sheet and cook in the preheated oven for about 2 to 3 minutes till the cheese bubbles and browns a little.
Serve it hot and enjoy this yumm!
