Passo a passo
Bone Broth
- In a large stock pot, add all ingredients for broth. Bring to a simmer. Let simmer for a minimum of 2 hours, but up to 4 hours.
- Skim off any fat from top of broth. Strain. Season with salt at the end. Set aside. Freeze if not used within 5 days.
Soup
- In a large pot on medium heat, add butter. When melted, saute onion and salt until soft and caramelized, about 15 to 25 minutes. Do not brown.
- Add beef broth, soy sauce, salt and pepper. Simmer for 30 minutes.
- Preheat broiler.
- On a sheet tray, fill mug with soup (about 75 to 80 percent of the way up).
- Place 1 slice of bread on top of each mug.
- Next, layer with 1/4 cup Swiss cheese followed by 1 slice of provolone as a “hat” right over the top of the mug.
- Heat under broiler until cheese melts, is bubbling and browned.
