This easy onion soup is a classic French recipe. In this version, condensed beef broth gives it lots of flavor. If the broth tastes too strong, add some water. Or use a good quality homemade or store-bought beef stock, preferably low sodium.

It's easy to fix and so satisfying. This is an excellent soup to serve as a luncheon soup, and it's hearty enough to serve as a dinner soup with crusty French bread and a salad.

If your soup bowls can stand the heat from the preheated broiler -- e.g., sturdy stoneware, cast iron, porcelain, etc. -- you can broil the bread and cheese directly on the hot soup.

 

What You'll Need

  • 3 tablespoons butter
  • 4 cups thinly sliced onions, about 4 to 5 medium onions
  • 4 (10 1/2 oz) cans condensed beef broth
  • 4 slices French bread, 1 inch thick
  • 4 tablespoons shredded Gruyere cheese, plus more for serving

How to Make It

  1. In a large skillet or saute pan over medium low heat, melt butter. Saute onion until very soft and golden brown in color, about 8 to 10 minutes.
  2. In a medium saucepan, combine the beef broth with the cooked onion; bring to a boil. Reduce the heat to low and cover the pan. Simmer for 25 to 30 minutes.
  3. Meanwhile, heat the broiler and place the French bread slices on a foil-lined baking pan. Toast the French bread about 4 inches from the heat until golden brown on both sides. Sprinkle each slice evenly with the Gruyere and Parmesan cheeses; broil just until cheese is melted and bubbling.
  1. Pour the onion soup into 4 individual soup bowls; float a slice of toasted French bread, cheese side up, in each bowl and sprinkle with extra cheese.
