Essential Ingredients

Thyme: Fresh thyme elevates the flavor profile; dried thyme can be used in a pinch.

Let’s Make it together
Slice Those Onions!: Begin by peeling and thinly slicing your onions. Aim for uniform slices so they cook evenly and caramelize beautifully.
Sauté with Love!: In a large pot, melt the butter over medium heat. Add your sliced onions and stir occasionally until they become golden brown and fragrant—about 20 minutes should do!
Add Some Flair!: Once your onions are caramelized, sprinkle in the thyme and stir well to combine. This will release lovely aromatic oils that enhance the dish’s depth.
Pour in the Broth!: Carefully add the beef broth to your pot, scraping up any bits stuck at the bottom. Let everything simmer together for about 15 minutes to meld those incredible flavors.
Prepare Your Bread!: While your soup simmers, slice your baguette into thick pieces and toast them lightly until golden brown. This step adds texture and prevents sogginess later.
Top It Off!: Ladle the hot soup into oven-safe bowls, place toasted baguette slices on top, and generously sprinkle with cheese. Broil those beauties until bubbly and golden—around 3-5 minutes does the trick!
Now that you’ve followed these steps, get ready to dig into a bowl of heaven! Enjoy each spoonful of this delicious onion soup mix—it might just steal the show at your next gathering!
