Let’s Make it Together
Sautéing Onions: Start by melting butter in a large pot over medium heat. Add thinly sliced onions and cook until they turn translucent and fragrant—about 10 minutes. Stir occasionally to prevent sticking.
Add Flavorings: Sprinkle in your onion soup mix along with some thyme while stirring well. Let these flavors mingle for another minute or two; you want every bit coated in oniony goodness.
Pour in Broth: Gradually add beef broth to the pot while scraping up any tasty bits stuck at the bottom—those are flavor nuggets! Bring it to a gentle simmer and enjoy those enticing scents filling your kitchen.
Prepare Bread and Cheese Topping: While waiting for the broth to simmer, slice your baguette into thick pieces and arrange them on a baking sheet. Top each slice generously with cheese; trust me, no one will complain about extra cheese!
Bake Until Golden Brown: Preheat your oven to broil and place those cheesy baguette slices under it until they bubble and turn golden brown—about 3-5 minutes should do it! Keep an eye on them; burnt cheese is tragic.
Serve It Up!: Ladle hot soup into bowls, float those cheesy baguette slices on top, and sprinkle with extra thyme if you’re feeling fancy! Enjoy every spoonful as laughter fills the air around you.
