Premade Real Mashed Potatoes at Costco

Mashed Potatoes at Costco - Yukon Gold - Thanksgiving and Christmas.

Back for a Thanksgiving cameo at my house, the Kirkland Signature deli pre-made real mashed potatoes at Costco are now in stores. These are extra large sized to feed a crowd – or see below for some of my serving ideas to use all of these up! A fall favorite, and holiday meal essential…these are REAL mashed potatoes without all the peeling, and boiling and mashing and seasoning…you just heat and serve!

I remove them from the packaging and microwave them. You can also move them into a baking dish and bake them to warm them up. Either way, these deli mashed potatoes from Costco are fully cooked, so do whatever is easier for you on the big day!

Why I like the Costco Mashed Potatoes

I’ve said it before and I’ll say it again…when hosting a large meal we all have to outsource some. In my opinion, peeling, boiling and mashing potatoes is pretty basic stuff. I can always add a little dash of this or that to these, but by shortcutting the whole process I save a lot of time and mess in my kitchen on a busy day.

Do I love that they have potassium sorbate? No. But for one side for one meal, I’ll accept it. It’s not an ingredient you’ll find in most food I choose, but on occasion, I’m okay with it.

I honestly can’t say that if I made mine homemade they’d taste any different. These are good, and I definitely recommend these as an item to outsource and just buy pre-made! I buy them and serve them at my Thanksgiving every year.

Ingredients

Yukon gold potatoes, whole milk, butter (cream and ore milk, salt), salt, potassium sorbate (preservative), spices, parsley.

Costco Price & Item Number

Yukon Gold mashed potatoes are Costco item number 14265 and cost $1.99 per pound. It’ll cost around $10 per package, give or take a buck or two.

These have not increased in price for 2023, one more inflation-proof Costco essential Thanksgiving meal essential!

It's quick and easy to heat up your Costco Yukon Gold premade mashed potatoes from the Deli. I always transfer mine to a ceramic baking dish and place them in the oven, but these are designed to be heated in their container if that's easier for you! Costco has swapped the container they come in from plastic (shown in pic) to an aluminum oven safe container - this may vary regionally so please check your packaging. Black plastic is microwavable, and silver aluminum is ovenable. They will be one or the other, but not both.

Alternatively, you can pop them into a microwave safe dish, and microwave for about 8 minutes, stop and stir them, then microwave another 8 minutes. Adjust a little lower if not heating the entire package. The aluminum dish they come in is ovenable but NOT microwaveable.
