Preheat oven to 350°
Melt butter in skillet and add diced onion pieces and cook with salt and garlic powder until light browning is achieved, about 5 minutes.
1 1/2 tablespoons butter, 1/2 red onion, 1 pinch salt, 1/8 teaspoon garlic powder
In a bowl, combine breadcrumbs, ground beef, worcestershire, thyme, salt, pepper, and parmesan cheese. Add onion pieces and combine into one homogeneous mixture.
1 cup breadcrumbs made from pulsing honey mustard pretzels flavored pretzels, 2 pounds 85/15 ground beef, 1 tablespoon worcestershire sauce, 1/2 teaspoon dried thyme, 1 teaspoon salt, 8-10 grinds black pepper, 1/3 cup grated parmesan cheese
Bake on a baking tray with parchment on it in the shape of a loaf - this prevents the meatloaf from soaking in its own little sauna of grease while it cooks.
While the meatloaf bakes, combine the ingredients for the glaze.
1 teaspoon salt, 1/2 teaspoon onion powder, 1 tablespoon mustard, 1 tablespoon lemon juice, 5 grinds black pepper
At about 110° (approximately 30-40 minutes of cooking), brush the glaze onto the outside of the meatloaf, being sure to heavily coat all sides.
Continue to cook until 170° (approximately 1 hour and 25 minutes total)
Allow to rest for 5-10 minutes before slicing. This isn't completely necessary but it will allow you to make whole slices. If you like your meatloaf piping hot and don't care if it falls apart a little bit, feel free to skip this step.
