Recipe preparation for Crockpot French Onion Soup

How to Make Crockpot French Onion Soup

Follow these simple steps to prepare this delicious dish:

Step 1: Slice Those Onions

Start by slicing your onions thinly; aim for about a quarter-inch thickness so they cook evenly. Grab your trusty chef’s knife and get chopping—feel free to shed a tear or two while reminiscing about those long-lost onion ring dreams.

Step 2: Sautéing Time

In a skillet over medium heat, melt your butter until it foams up like a puppy in springtime. Add the sliced onions and sprinkle with salt. Stir occasionally until they turn golden brown and caramelized—this should take about 20-30 minutes.

Step 3: Assemble It All

Step 4: Slow Cook Magic

Cover your crockpot and let it work its wonders on low heat for about 6-8 hours. Go ahead and binge-watch that series you’ve been meaning to catch up on while your soup simmers away!

Step 5: Prepare the Baguette

About half an hour before serving, slice your baguette into thick pieces—aim for at least one inch—and toast them until golden brown in the oven at 400°F (200°C). If you’re feeling cheeky, rub them with garlic after toasting!

Step 6: Serve It Up

Ladle the soup into oven-safe bowls, place a toasted baguette slice atop each bowl, and generously sprinkle Gruyère cheese over everything. Pop them under the broiler for about five minutes until bubbly and golden brown—just be careful not to burn down your kitchen!

Transfer to plates and drizzle with sauce for the perfect finishing touch. Enjoy every soothing sip of this incredible Crockpot French Onion Soup!
