This savory meatloaf recipe features a tangy glaze and a moist, flavorful interior, perfect for a comforting meal.
Preheat your oven to 375°F (190°C).
Preheating ensures even cooking from the start.
In a large mixing bowl, combine the ketchup, salt, black pepper, red pepper flakes, egg, breadcrumbs, onion, and mustard. Mix until well combined.
Mix gently to avoid compacting the meat mixture.
Add the ground beef to the bowl and gently mix until just combined.
Overmixing can make the meatloaf dense.
Line a loaf pan with aluminum foil and press the meat mixture into the pan evenly.
Lining the pan with foil makes cleanup easier.
Bake the meatloaf in the preheated oven for 40 minutes.
Check the meatloaf halfway through to ensure even cooking.
While the meatloaf bakes, prepare the glaze by mixing ketchup, brown sugar, and mustard in a small bowl.
Adjust the sweetness of the glaze to your preference.
After 40 minutes, remove the meatloaf from the oven and spread the glaze evenly on top.
Use a spatula for an even layer of glaze.
Return the meatloaf to the oven and bake for an additional 10 minutes.
This step caramelizes the glaze for added flavor.
Let the meatloaf rest for 5 minutes before slicing and serving.
Resting allows the juices to redistribute, keeping the meatloaf moist.
