The warehouse giant isn’t disappointing this season either, with the return of one of its classic holiday side dishes we can’t wait to stock up on. Reser’s Main St. Bistro Baked Scalloped Potatoes Costco recently brought back its popular Reser’s Main St. Bistro Baked Scalloped Potatoes just in time for fall and the upcoming holidays. The best part? These potatoes are super easy to heat and serve. Just pop them in the microwave or oven for a few minutes, and you can serve them right in the tray they come in. Instagram user @costcohotfinds spotted the latest offering at Costco, saying, “They’re phenomenal!” The post adds that these scalloped potatoes are “made with real milk, butter, cheddar cheese, and sour cream,” creating the “perfect rich and creamy side dish.” Others quickly agreed, leaving comments like “This is SUCH a seriously good product” and “So easy and perfect for a quick meal and busy weeknight!” Over on Reddit, there have been countless threads dedicated to these fan-favorite potatoes over the years, with one user saying they are “almost as good as homemade” and another adding, “They were a hit! 10/10 would buy again.” You’ll find these scalloped potatoes in the refrigerated section of your local Costco. Some shoppers have spotted the 2.5-pound packages priced around $7.79, though they’ve also been seen for slightly less on Instacart, depending on your location. If you’re looking to stock up on Reser’s Main St. Bistro Baked Scalloped Potatoes this season, you might want to act fast.
