Instructions:
- Preheat Oven: Set your oven to 350°F (175°C). Line a loaf pan with parchment paper or lightly grease a baking sheet if you prefer a firmer crust on your meatloaf.
- Mix Ingredients: In a large bowl, combine the ground beef, egg, onion, milk, bread crumbs, 1/4 cup ketchup, Worcestershire sauce, garlic, salt, pepper, and thyme. If using, also add the bell pepper or carrot. Mix everything together until just combined. Avoid overmixing to prevent the meatloaf from becoming tough.
- Shape the Meatloaf: Transfer the mixture to the prepared loaf pan and press it down into an even layer. If using a baking sheet, form the mixture into a loaf shape directly on the sheet.
- Prepare the Glaze: In a small bowl, mix together the 1/2 cup ketchup, brown sugar, apple cider vinegar, and mustard. Spread half of this mixture over the top of the meatloaf before baking. Reserve the remaining glaze for later.
- Bake: Place the meatloaf in the oven and bake for about 1 hour, or until the internal temperature reaches 160°F (71°C). Halfway through the baking time, spread the remaining glaze over the top if desired.
- Rest Before Serving: Once done, remove the meatloaf from the oven and let it rest for 10 minutes before slicing. This rest period allows the juices to redistribute, making the meatloaf moist and easier to slice.
- Serve: Slice the meatloaf and serve it warm. It pairs wonderfully with sides such as mashed potatoes, green beans, or a simple salad.
Enjoy your delicious homemade meatloaf dinner!
