Tip: You’ll find the full list of ingredients and measurements in the recipe card below.
lean ground beef
yellow onion (thinly sliced)
unsalted butter
olive oil
garlic cloves (minced)
breadcrumbs
milk
large egg
Worcestershire sauce
fresh thyme or dried thyme
salt and pepper
beef broth (for gravy/glaze)
brown sugar or ketchup (for glaze)
optional: caramelized onion bits mixed into the mix

directions

1. Preheat your oven to 350°F (175°C).
2. In a skillet, heat butter and olive oil over medium heat. Add sliced onions and cook slowly until deeply caramelized—about 25–30 minutes. Add garlic near the end and cook 1–2 minutes more. Remove half the onions and reserve for topping/glaze; stir the rest into the meat mixture.
3. In a large bowl, combine ground beef, caramelized onions (half), breadcrumbs, milk, egg, Worcestershire sauce, thyme, salt, and pepper. Mix gently until just combined.
4. Shape the mixture into a loaf and place it in a greased baking pan or loaf pan.
5. Bake for about 45–55 minutes, until internal temperature reaches 160°F (71°C).
6. While the loaf bakes, make the glaze: In the skillet used for onions, add beef broth and brown sugar or ketchup. Stir to combine and simmer until thickened slightly. Stir in the reserved caramelized onions.
7. During the last 10 minutes of baking, brush the glaze over the meatloaf.
8. Once done, remove from oven and let rest for 10 minutes before slicing.
