Combine all meatloaf (not meatloaf glaze) ingredients in a large bowl. Mix the meatloaf until everything is well combined.
Place all mixed meatloaf ingredients on a parchment-lined sheetpan and, using your hands, shape into a bread loaf-shaped mass. Pack it fairly tight so that everything stays together.
Pre-heat oven to 425°F (220°C) and then add your meatloaf to the oven and reduce the heat in the oven to 350°F (177°C).
Set a timer for 15 minutes and start to make your glaze.
Add all meatloaf glaze ingredients into a small saucepan over medium heat. When brown sugar has melted and all ingredients are combined, take your glaze off the heat.
Pull the meatloaf out after 15 minutes and, with a brush or spoon, paint the glaze on top every 15 minutes or until an hour has passed. After an hour, or 1 hour and 15 minutes, the meatloaf should be done, but you can check with a thermometer if you have one. The interior of the meatloaf should be at 155°F (68°C) when you pull it out. Carry over heat will bring the meatloaf to a safe 160 degrees.
