How to cook deliciously - French Onion Soup Gratinée
1. Stage
Melt butter in a large pot over medium-high heat. Stir in red onions, sweet onions, and salt. Cook, stirring frequently, until onions are caramelized and almost syrupy, about 35 minutes. Dotdash Meredith Food Studios

Stir in chicken broth, beef broth, red wine, and Worcestershire sauce. Bundle parsley, thyme, and bay leaf with kitchen twine; add to the pot. Simmer over medium heat for 20 minutes, stirring occasionally. Remove and discard herb bundle. Reduce heat to low; stir in vinegar and season with salt and pepper. Cover soup and keep warm over low heat while you prepare the toast. Dotdash Meredith Food Studios
3. Stage
Set an oven rack about 6 inches from the heat source and preheat the oven's broiler. Arrange bread slices on a baking sheet and broil, turning once, until well toasted on both sides, about 3 minutes. Remove from heat; do not turn off the broiler. Dotdash Meredith Food Studios
4. Stage
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 of toasted bread, 2 slices Gruyère cheese, and 1/4 of the Asiago cheese. Sprinkle a little bit of paprika over the top of each one. Dotdash Meredith Food Studios
5. Stage
Cook under the hot broiler until bubbly and golden brown, about 5 minutes. Cheese will cascade over the sides of the crock and form a beautifully melted crusty seal as it melts. Dotdash Meredith Food Studios
