How to Make French Onion Soup
Caramelizing the Onions
Start by slicing your onions thinly; aim for about a quarter-inch thickness to ensure even cooking. Melt butter in a large pot over medium heat until it begins to foam slightly. Add the sliced onions and stir them gently, coating them in butter. Cook these beauties low and slow for about 30 minutes while stirring occasionally until they turn golden brown and fragrant.
Add the Broth and Wine
Once your onions reach that perfect caramelized state—think beautiful amber color—pour in your dry white wine. Scrape up any browned bits from the bottom of the pot as this adds incredible depth of flavor! Allow it to simmer for about five minutes until slightly reduced before adding beef broth next. Bring everything to a gentle boil then reduce heat and let it simmer for another 20 minutes.
Prepare the Bread Topping
While waiting for those flavors to meld together, slice your stale baguette into half-inch thick pieces; we want maximum surface area for cheese coverage! Toast these slices lightly in a separate oven or skillet until golden brown—this step ensures they won’t turn mushy when placed atop your soup later.
Assemble and Broil
Ladle hot soup into oven-safe bowls filled halfway with broth goodness before placing toasted baguette slices on top of each bowl generously covering them with Gruyère cheese. Set these bowls under the broiler in your oven until cheese bubbles and turns golden brown—about five minutes should do it!
Enjoy this delightful bowl of warmth that’s guaranteed to make you feel cozy inside out! If you’re lucky enough to have leftovers (which is rare), just reheat gently on the stove!
