How To Make Costco Meatloaf and Mashed Potatoes
Make the Meatloaf:
- Sauté the Vegetables: Heat the olive oil in a sauté pan. Sauté the carrots until soft, then remove them to a large bowl. In the same pan, sauté all the minced garlic (for both meatloaf and potatoes) until slightly golden. Set aside 1 tablespoon of the garlic for the mashed potatoes.
- Mix the Meatloaf: To the large bowl with the carrots, add the ground turkey, oats, ketchup, BBQ sauce, parsley, the remaining sautéed garlic, salt, and pepper. Use your hands to gently mix the ingredients until just well blended.
- Shape and Bake: Form the mixture into a loaf shape (about 4 inches wide and 8-9 inches long) and place it on a baking sheet, or press it into a standard loaf pan. Spread the extra 1/4 cup of ketchup or BBQ sauce over the top.
- Bake the Meatloaf: Bake uncovered at 350°F for about 1 hour and 10 minutes. Let the meatloaf rest for 5-10 minutes before slicing and serving.
Make the Mashed Potatoes:
- Boil the Potatoes: While the meatloaf bakes, add the potatoes to a pot of boiling water and cook for about 15 minutes, or until they are tender but not falling apart.
- Mash the Potatoes: Drain the water and return the potatoes to the pot. Add the butter, milk, Parmesan, Asiago, the reserved 1 tablespoon of sautéed garlic, salt, and pepper. Mash with a potato masher to your desired consistency.
- Serve: Sprinkle the mashed potatoes with fresh parsley and serve alongside the sliced meatloaf.

Recipe Tips
- How do I keep the meatloaf moist? The quick-cooking oats are the secret ingredient here. They act as a binder and absorb the juices, keeping the lean ground turkey incredibly moist. Also, be careful not to overmix the meat mixture.
- Can I use a different kind of meat? Yes, this recipe is very versatile. You can easily substitute the ground turkey with lean ground beef or ground chicken.
- How do I get the creamiest mashed potatoes? Mashing the potatoes while they are still hot is key. This allows the butter and cheeses to melt completely and incorporate smoothly. Using warm milk also helps create a creamier texture.
- Can I make this ahead of time? You can prepare the meatloaf mixture a day in advance and store it in the refrigerator. You can also boil the potatoes ahead of time. When ready to cook, simply shape and bake the meatloaf, and mash the pre-cooked potatoes.
What To Serve With Meatloaf and Mashed Potatoes
This classic dinner is a complete meal, but it’s even better with a simple side.

How To Store Meatloaf and Mashed Potatoes
Store: Place any leftovers in an airtight container, keeping the meatloaf and mashed potatoes separate if possible. Store in the refrigerator for up to 3 days. Reheat: Reheat individual portions in the microwave until hot. You can add a splash of milk to the potatoes when reheating to make them creamy again.

FAQs
Quick-cooking oats are a fantastic binder for meatloaf. They absorb moisture and flavor, helping to keep the meatloaf tender and juicy, and they provide a better texture than traditional breadcrumbs in this recipe.
Yes. You can free-form the meatloaf into a log shape and bake it on a foil-lined baking sheet. This method actually allows the outside of the meatloaf to get a nice caramelized crust all around.
Starchy potatoes like Russets or Yukon Golds are the best choice for mashing. They break down easily and absorb the butter and dairy well, resulting in a light and fluffy texture.
