1
Prepare the Broth
In a large slow cooker, add the beef bones, water, thyme, bay leaves, salt, and pepper. Cook on low for 9 hours.
2
Sauté the Onions
In a large skillet, heat the olive oil over medium heat. Add the thinly sliced onions and cook until caramelized, about 30-40 minutes, stirring frequently.
3
Combine and Simmer
After the broth has cooked for 9 hours, strain the liquid into a large pot. Add the caramelized onions and minced garlic to the pot and simmer for an additional 30 minutes.
