Follow these simple steps to prepare this delicious dish:
Step 1: Slice Those Onions
Grab your trusty chef's knife and thinly slice about four large onions. Don’t worry if you shed a tear or two; it’s all part of the onion-slicing experience!

In a large pot over medium heat, melt about four tablespoons of butter. Toss in those sliced onions and stir occasionally. Let them cook down slowly until they turn golden brown and smell unbelievably sweet—this should take about 30 minutes.
Step 3: Add Wine
Pour in half a cup of dry white wine to deglaze the pot. Scrape up any tasty bits stuck at the bottom while letting that wine reduce by half.

While your soup simmers, preheat your oven to broil. Arrange baguette slices on a baking sheet, sprinkle them lightly with olive oil, and toast them until golden brown—about three minutes on each side should do the trick.

Ladle hot soup into bowls, place toasted baguette slices atop each serving, and generously sprinkle grated Gruyère cheese over everything. Pop them under the broiler until bubbly and golden—watch closely so they don’t burn!
