To cook Costco meatloaf and mashed potatoes, preheat your oven to 350°F, cook the meatloaf according to package instructions, and prepare the mashed potatoes by boiling, mashing, and mixing in butter and milk.
Start by removing the meatloaf from its packaging. Place it in a baking dish and cover it with foil. This helps it cook evenly and stay moist.
While the meatloaf is baking, peel and chop your potatoes. For a creamy texture, use Yukon Gold or Russet potatoes.
Boil the chopped potatoes in salted water until they’re fork-tender. This usually takes about 15-20 minutes.
Drain the potatoes and return them to the pot. Add in butter and a splash of milk. Mash them until smooth and creamy. Adjust the butter and milk to achieve your desired consistency.
Once the meatloaf reaches an internal temperature of 160°F, take it out of the oven. Let it rest for about 10 minutes before slicing. This makes it easier to serve.
Serve the sliced meatloaf alongside the mashed potatoes. You can add gravy on top of the meatloaf for extra flavor, if desired.
