Costco Scalloped Potatoes - Is It Any Good? Full Review


Baked Scalloped Potatoes at Costco

Costco sells Reser’s Main St Bistro Baked Scalloped Potatoes for $6.99. 

The scalloped potatoes are located in the refrigerated deli area of the warehouse near prepared items such as the Twice Baked PotatoesPork Schnitzel, or the Beef and Lamb Gyro Meat Slices.


Main St. Bistro’s scalloped potatoes from Costco are sold in a 2.5 Pound package and are made with real cheddar cheese and unlike Costco’s dehydrated hash browns, these use fresh potatoes. 

There are no artificial colors, flavors, or preservatives, but they do contain bioengineered food ingredients.

What are Scalloped Potatoes?

Scalloped Potatoes get their name from the old English word “collop” which means to thinly slice something. 

So scalloped potatoes are thin sliced potatoes that are baked in milk, cream, or cheese. 


With these baked scalloped potatoes from Costco, the top few listed ingredients are either potatoes or a dairy product such as milk, cheddar cheese, butter, skim milk, parmesan, or sour cream.

Costco Cost Comparison - Scalloped Potatoes

Scalloped Potatoes Price at Costco

Costco’s Scalloped Potatoes sell for $6.99, but can be had $4.99 when they are on sale. This is a $2 discount or 28% off. 

The price per pound of the scalloped potatoes drop from $2.80 a pound down to $2.00 per pound.


Does Costco Have The Best Price?

Sam’s Club sells the same 2.5 Pound Package of Main St. Bistro Scalloped Potatoes for $5.38. This price is significantly better than Costco’s retail price of the potatoes and only slightly more than Costco’s sale price. 

I’m a little disappointed here with Costco’s price. I did think the scalloped potatoes were on the pricey side at $7 for the package, but I didn’t think they would get beat by Sam’s club this badly in price.

Main St Scalloped Potatoes Costco - taste Test

The heating instructions are fairly simple and I opted for the oven bake method of cooking Costco’s scalloped potatoes. 

They are already at least partially precooked, so these can be heated in the microwave if you choose to do so. 


I cooked the scalloped potatoes for about 24 minutes but I think they could have used a little more time in the oven. Some of the potato slices felt a little underdone. 

Exterior was underwhelming

Like most people, my favorite part of scalloped potatoes is the crispy crunchy browned potato crust. 

I love the upper crust, but unfortunately, Main St Bistro’s scalloped potato didn’t give me enough of that golden brown crust that I’m looking for. 

Uncooked Costco Scalloped Potatoes

Underdone Potatoes

Even following the instructions, my potatoes came out a little bit under. I think they could have used another few minutes in the oven. 

I wanted some really soft and tender potatoes, but with my cook, some of the potatoes were still hard and not cooked through.


The inner potatoes were covered in cheese and cream which was nice, but they were lacking in taste. 

I felt the cheese sauce was bland and the potatoes didn’t pack as much flavor as I expected.


Overall, I didn’t really care for the scalloped potatoes from Costco. 

We ate them as part of a simple meal with chicken thighs and they were just fine. It was sub-par in presentation, texture, and taste, and I think there are much better side dishes to purchase or even make at home. 

Baked Scalloped Potatoes from Costco Cooking/Heating Instructions

Main St Bistro provides two options in heating or cooking the scalloped potatoes. For this item, I would much prefer to cook them in the oven over the microwave. 


How to Cook Reser's Scalloped Potatoes


  • Preheat Oven to 350°F
  • Remove the tray from the package and remove film.
  • Place the container on a baking tray and heat potatoes in the oven for 20–25 minutes or until hot. 

Caution: Product and package will be hot. Do not prepare in Toaster Oven. Do Not Broil


  • Remove the tray from the package and remove film.

Nutritional Information

How Many Calories in Reser's Scalloped Potatoes?

There are 8 total servings in each package of Main St. Bistro’s Scalloped Potatoes. Each serving is two-thirds of a cup or 140 grams (4.9 ounces) and contains 210 calories with 11 grams of fat, 20 grams of carbs, and 7 grams of protein. 


Are Scalloped Potatoes Healthy?

Plain and simple, you aren’t eating these scalloped potatoes because you are on a diet. They aren’t going to be healthy for you and there are many other healthier Costco side dish options such as broccoli or maybe even Madras lentils that would be better diet options. 

Taking all that into consideration, I think the nutritional profile is understandable. 

All 3 of the fat, carbs, and protein are fairly standard and not out there one way or the other. The sodium is also pretty standard (for a Costco deli food option) at 470mg per serving or 20% of the recommended daily value. 

This is more sodium that you want to take on per serving, but actually less than what I expected for a processed food.

How many people does Costco Scalloped Potatoes Serve?

According to the packaging, one package of baked scalloped potatoes from Costco is 8 servings. Don’t be fooled into thinking that 8 people can be fed from one package though. 

After serving this in my household which is made up of 2 adults and 2 small toddlers, I would estimate that this would feed 4-5 adults.

Final Thoughts

The scalloped potatoes from Costco are a letdown. They are mild in flavor and there wasn’t enough of the crispy crust that I love. The scalloped potatoes are also on the more expensive side. 

If you do want to give them a try, they are going to be better for a casual weeknight dinner rather than something you would serve to guests.
