Costco Reser’s Main St. Bistro Baked Scalloped Potatoes Review

I have to admit, scalloped potatoes aren’t my favorite. I’ll take mashed potatoes, baked potatoes, oven-roasted potatoes or fries over scalloped potatoes any day. I don’t hate them, but for some reason, they’re just not overly appealing to me. I say this so you’ll understand that these Reser’s Main St. Bistro Baked Scalloped Potatoes from Costco weren’t going to have an easy time winning me over! Were they good enough to impress this scalloped potato skeptic?

Location in Store

These scalloped potatoes were located in the refrigerated deli section near the Kirkland Signature Beef Pot Roast and the Cuisine Solutions Sliced Grass-fed Beef Sirloin. The item number is 1658964 and I bought them in Kalispell, Montana but I just saw them at my Costco here in Edmonton!

I’ll admit it – I’m not a huge fan of scalloped potatoes, even homemade ones. They’re alright, but they’re not my favorite. For that reason, I wasn’t overly excited to try these ones. I ended up being pleasantly surprised though!

The potatoes are very creamy, but mild in flavor. They’re more creamy than cheesy if that makes sense.

They look cheesier than they taste.

I saw parmesan and romano cheese on the ingredients list and was worried the potatoes would have a strong cheese flavor that I wouldn’t like, but they don’t. There aren’t any standout flavors in the seasoning either.

As far as texture goes, the potatoes are mostly soft and smooth (but see my comment below on the cooking time). The cheddar cheese on top has a small amount of texture to it, but not much. Unfortunately, the box clearly says not to broil them or that might be an option for crisping them up on top.

My biggest complaint about the potatoes is that I cooked them for 25 minutes (the high end of the recommended cooking time) at 350 degrees Fahrenheit and my potatoes were still a tiny bit crunchy. They weren’t crunchy enough to stop me from enjoying them, but they were crunchier than scalloped potatoes should be. I’d bake them a little longer next time.

These scalloped potatoes are heavy and creamy, but I actually enjoyed them a lot. If they can win over a scalloped potato skeptic like me, I suspect most people will enjoy them. Just make sure they’re cooked to your liking!

The two-and-a-half pound or 1.13 kilogram tray costs $7.79 USD and $10.89 Canadian.

The scalloped potatoes can either be microwaved or baked in the oven, I decided to bake mine in the oven because it’s not any more work than microwaving them. I baked my potatoes for 25 minutes at 350 degrees Fahrenheit and found they were still a tad bit crunchy.

A surprisingly convenient meal!

They’re fully prepared so all you need to do is heat them and serve! I served the potatoes with turkey, stuffing and cranberry sauce.

The scalloped potatoes need to be kept refrigerated and the best-before-date is about five weeks from when I purchased them. These go well with ham, turkey, meatloaf, chicken or any other kind of meat.

The ingredients list is pretty typical for store-bought prepared scalloped potatoes. There’s a lot of calorie-dense ingredients listed like whole milk, cheese, sour cream, heavy cream and butter.

  1. I’m surprised at all the comments about the potatoes being hard/crunchy after cooking. I’ve made them several times and they’ve always turned out great. I do cook them at 350 for 40-45 minutes so maybe that’s why?

  2. These were totally undercooked for some strange reason as I always believed the longer they bake/roast, the more tender they’d be -nope. On my second attempt with these, I left them in the oven for 1.5 hours! Yep, ONE and A Half HOURS and they still came out crunchy. A big no for us. Shame, because as mentioned by many, these have great potential but they must have some coating or something on them that prevents them from properly baking to an appropriate doneness idk.

  3. I am a Scalloped Potato Fan. Costco currently sells a 40 oz. size, which is larger than most grocery stores that carry Reser’s Main St.

    Here is a FLASH: the potatoes are on the current Member-Only Savings, August 30 – September 24, 2023. I just bought a package with $2.80 off ($7.79 less $2.80 = $4.99). I may have to get some more. Does anyone know if this item will freeze?

    • Fred, I actually bought an extra during that sale and put it in the freezer. Cooking it tonight so I will come back and let you know how they turned out 🙂

      • Update: I cooked them from frozen at 350 for 1hr 20 min on a baking sheet and covered with tinfoil. They looked the same and tasted good but were a little dry. I won’t cook them directly from frozen again (maybe thaw overnight before baking)

  4. Publix has these on a BOGO a lot and I think Walmart might still sell them. I buy these and the Au Gratin whenever on sale. The company has new varieties of taters other than scalloped and they do have several varieties of mashed.
