Sweet Onion & Bread Soup

Why I Love This Recipe
This is one of the only recipes that I haven't tried, but I thought it was right up your alley, Mom. I will give it a whirl soon and let you know if it's gross. It would probably be delicious with a pretzel grilled cheese.

Ingredients You'll Need
8 oz sourdough bread (or any other dense, dark bread)

3 large garlic cloves (or 5 medium ones)
2 1/2 cups chicken broth

Directions
Cube the bread. Peel and slice the onions and grate the garlic. Heat 1/2 of the butter in a skillet. Toss in bread and cook until crispy. Add 1 cup of milk and turn off heat.
Heat remaining butter and cook the onions, garlic, & thyme for 20-30 min. Add chicken broth and bread cubes and simmer on low for 10 minutes.
