Instructions:
Caramelize the Onions
Heat butter and olive oil in a skillet over medium heat.
Add onions, salt, pepper, and thyme. Cook, stirring occasionally, for 20-25 minutes until deeply golden.
Stir in beef broth and Worcestershire sauce, cooking for 2 more minutes. Set aside.
Make the Meatloaf Mixture
In a large bowl, mix ground beef, breadcrumbs, eggs, beef broth, Worcestershire sauce, salt, pepper, garlic powder, and onion powder until well combined.
Assemble the Meatloaf

On parchment paper, flatten the meat mixture into a 10×12-inch rectangle.
