2 cartons of beef broth (32oz) or substitute mushroom broth
baguette, sliced into 1 inch pieces
1 cup Gruyere cheese, shredded
Instructions
Start by drizzling a bit of olive oil on the bottom of a large pot over medium high heat.
Add 2 tablespoons butter.
Next add the sliced onions, thyme and garlic.
Cook for about 25 minutes on medium- low heat. You do not want the onions to burn so be sure to stir them every few minutes. They should start to get nice and brown and caramelized.
Add 2 tablespoons flour to the onions and stir in well.
Cook for 5-10 more minutes just so you don't have a raw flour taste to your soup.
If you used fresh thyme, remove the stems from the pot.
Add the beef broth and bring to a boil.
Reduce heat and let simmer about 30-45 minutes.
Add salt and pepper to taste.
