Osso Bucco is cut like thick steak, and eats like fall apart roast. Internet recipies (European usually) are similar to each other with seared meat, veggies, tomato paste, wine or beer and broth. Then slow cook.
Simply use a dutch oven or crock pot or lidded pot or pressure cooker.
The Giada recipe was great. We simplified it - no string, no cheese cloth, no wine, no celery. Just browned/seared the meat in avacado oil (then salt and pepper), started onions and carrots, added broth and cooked.
Tip: stand the cuts on end.
