I tried this for dinner last night, and WOW

Form meatloaf: Place the meat mixture in the baking dish that has been preheated and form it into a loaf.
Garnish with ketchup, brown sugar, and Dijon mustard, which you should combine in a small bowl. Drizzle over the meatloaf.
The internal temperature should reach 160°F (71°C) after 50-60 minutes in the oven.
While the meatloaf is in the oven, boil some chopped potatoes in a big saucepan with some cold water to make mashed potatoes. Raise the heat to high and season with a pinch of salt. After around fifteen to twenty minutes of cooking, the vegetables should be soft. Drop into the saucepan and stir. Incorporate the butter and milk. Mash until it becomes creamy and smooth. Finish with a pinch of pepper and salt.
Put the meatloaf in the oven and when it's done, cover it with mashed potatoes. On top, crumble some cheddar cheese. Melt and bubble the cheese by broiling for three to five minutes.
Prior to slicing and serving, let the meatloaf to rest for 10 minutes. Sprinkle chopped parsley on top.
Pile on the mashed potatoes and cheese for a satisfying meatloaf meal.
