Costco Scalloped Potatoes {Reser’s Main St Bistro}

One of my favorite weeknight dinner hacks is to cook up a batch of the scalloped potatoes from Costco {Reser’s Main Street Bistro}.  These potatoes are cheesy,  easy to make and completely filling.

I figure that serving these potatoes is only slightly more expensive than making them from scratch and saves me a ton of valuable time.

Are Costco Scalloped Potatoes Good?

I think the Reser’s Main St Bistro potatoes are delicious.

The potatoes have a wonderful cheddar cheese sauce that gets brown and bubbly when cooked.  The potatoes are thin sliced and hold the sauce well.

The dish is well seasoned and by that I mean that it has enough salt to perk up the flavors but is not drowning in salt like most commercially processed foods.

My only complaint about these potatoes is that sometimes I will get a few pieces that feel a little harder than I prefer.  I like scalloped potatoes to be almost mushy and these, while fully cooked, sometimes have more texture than I prefer.  I could probably fix that by heating them up a little longer next time.

How Long Do I Cook Costco Scalloped Potatoes?

There are cooking instructions for this product for using an oven or a microwave. The instructions clearly state that you should not cook these potatoes in a toaster oven or by using a broiler.

Microwave Cooking Instructions

  • Remove tray from package and remove film.
  • Heat on High for 7-8 minutes or until hot.
  • Let it stand for 1 minute before serving.

I slightly modify these cooking instructions.

Instead of completely removing the film I peel it back and then lay it back over the potatoes.   This keeps the potatoes vented while they cook in the microwave but also prevents and splattering and keeps my microwave clean.

Oven Cooking Instructions

  • Preheat oven to 350F.
  • Remove tray from package and remove film.
  • Place tray on baking tray and heat for 20-25 minutes until hot.

Should You Buy These Potatoes?

The 40 oz. package of Main Street Bistro Scalloped Potatoes costs $6.99.  You get eight servings (2/3 cup per serving) in a package for a cost per serving of $0.87.

While paying slightly under $1 per serving for a side dish isn’t exactly a bargain it also isn’t that expensive.  I suspect that you could make these from scratch for a cost of around $0.65 per serving but when you factor in your time and the hassle then these pre-made potatoes start looking like a pretty good deal.

The Main Street potatoes are delicious, relatively healthy, easy to prepare and are sold at a fair price.

I buy them on a regular basis and think you will enjoy them if they land up in your shopping cart!
