Time 1h15m

Yield 4

Number Of Ingredients 17

4 tablespoons butter
1 teaspoon salt
2 large red onions, thinly sliced
2 large sweet onions, thinly sliced
1 (48 fluid ounce) can chicken broth
1 (14 ounce) can beef broth
½ cup red wine
1 tablespoon Worcestershire sauce
2 sprigs fresh parsley
1 sprig fresh thyme leaves
1 bay leaf
1 tablespoon balsamic vinegar
salt and freshly ground black pepper to taste
4 thick slices French or Italian bread
8 slices Gruyere or Swiss cheese slices, room temperature
½ cup shredded Asiago or mozzarella cheese, room temperature
4 pinches paprika

Steps:

  • Melt butter in a large pot over medium-high heat. Stir in salt, red onions and sweet onions. Cook 35 minutes, stirring frequently, until onions are caramelized and almost syrupy.
  • Mix chicken broth, beef broth, red wine and Worcestershire sauce into pot. Bundle the parsley, thyme, and bay leaf with twine and place in pot. Simmer over medium heat for 20 minutes, stirring occasionally. Remove and discard the herbs. Reduce the heat to low, mix in vinegar and season with salt and pepper. Cover and keep over low heat to stay hot while you prepare the bread.
  • Preheat oven broiler. Arrange bread slices on a baking sheet and broil 3 minutes, turning once, until well toasted on both sides. Remove from heat; do not turn off broiler.
  • Arrange 4 large oven safe bowls or crocks on a rimmed baking sheet. Fill each bowl 2/3 full with hot soup. Top each bowl with 1 slice toasted bread, 2 slice Gruyere cheese and 1/4 of the Asiago or mozzarella cheese. Sprinkle a little bit of paprika over the top of each one.
  • Broil 5 minutes, or until bubbly and golden brown. As it softens, the cheese will cascade over the sides of the crock and form a beautifully melted crusty seal. Serve immediately!

FLORENTINE CARAMELIZED ONION SOUP



Florentine Caramelized Onion Soup image

Also known as "carabaccia", this is a local specialty in Florence, and is hard to find even in cookbooks specializing in Italian soups! The effect should be rich and somewhat sweet (but not too much). Adding roasted garlic would be a good variation.

CARAMELIZED ONION SOUP AU GRATIN (LOW CARB, BUT YOU WON'T NOTICE



Caramelized Onion Soup Au Gratin (Low Carb, but You Won't Notice image

The secret behind this lower-carb recipe is the slow, low heat for the carmelization of the onion. Don't rush it - you won't regret it! Very tasty!

Provided by Julesong

Categories     Vegetable

Time 45m

Yield 1 serving(s)

Number Of Ingredients 8

1/2 cup chopped onion
1 tablespoon shallot, minced
3 tablespoons butter
1 (1 g) packet Splenda sugar substitute
1 cup beef broth
1/2 ounce dry sherry
1 slice wasa
2 ounces shredded gruyere cheese

Steps:

  • In a 3- to 4-quart pan, combine onion, shallots, butter, and Splenda over medium heat.
  • Cook, stirring often, until onion is slightly caramelized and tastes very sweet, about 35 minutes.
  • (If onion begins to brown too quickly, reduce heat to medium-low.) To pan, add broth and sherry.
  • Bring to a simmer over medium-high heat.
  • Pour soup into ovenproof bowl.
  • Top with Wasa and cheese.
  • Place bowl on baking sheet; broil 6 inches from heat until cheese is bubbling and lightly browned, about 3 minutes.

Tips:

  • Use a variety of onions. Yellow onions are the most common type used for caramelized onions, but you can also use white, red, or even shallots. Each type of onion has a slightly different flavor, so feel free to experiment to find your favorite.
  • Slice the onions thinly. This will help them caramelize evenly and prevent them from burning.
  • Cook the onions slowly and patiently. Caramelizing onions takes time, but it's worth it. The slower you cook them, the more flavorful they will be.
  • Don't overcrowd the pan. If you add too many onions to the pan, they will steam instead of caramelize.
  • Use a heavy-bottomed pan. This will help distribute the heat evenly and prevent the onions from burning.
  • Be patient. Caramelizing onions can take up to an hour, so don't rush the process.

Conclusion:

Caramelized onion soup au gratin is a delicious and comforting dish that is perfect for a cold winter day. It's also surprisingly easy to make, especially if you use pre-caramelized onions. So next time you're looking for a quick and easy meal, give this recipe a try. You won't be disappointed!
