1: Heat ¼ cup olive oil in a pan over medium heat to caramelize onions. Add onions, reduce heat to medium low, cover and let cook for 15 minutes.
2: Remove the lid and continue cooking, stirring periodically, to prevent onions from browning too quickly until they are light golden, about 30 minutes. Remove from pan and set aside.
3: In a large bowl, combine ground beef, panko, egg, minced garlic, worcestershire, ketchup, salt, and onion powder, and mix well.
4: Divide meat mixture into four balls and form each ball into a 1 inch thick patty.
5: Increase temperature to medium and add patties into the pan. Brown on both sides, about 5 minutes per side, then remove from pan and set aside.
6: Add sliced mushrooms to the pan with the steak fat and sauté until browned, about 10 minutes.
7: While mushrooms cook, whisk flour and a splash of bone broth in a small bowl to create a slurry.
8: Add caramelized onions, thyme, bone broth, flour slurry, worcestershire, and a pinch of salt and pepper to the pan, whisking well.
9: Return steaks to the pan and continue cooking in the sauce until thickened to your desired consistency, about 5 minutes.
