Costco offers several ways to simplify Thanksgiving sides, from prepared dishes to sides bundled into online holiday meals. The options below are examples—not a guarantee of six items stocked at every warehouse—and the available listings do not support a reliable nationwide price-per-serving ranking. Check your local warehouse or Costco SameDay before building your menu.
Prepared sides to look for at Costco
Kirkland Signature mac and cheese
Costco SameDay listed an estimated 3.78-pound package for $17.12 when the listing was observed. That is a local listing detail, not a national or lasting price; check your own SameDay results for current cost and stock. View Costco SameDay.

Kirkland Signature loaded mashed potatoes
The SameDay listing described a roughly 3.6-pound package with potatoes, butter, Parmesan, bacon, mozzarella, and sour cream. It appeared out of stock in the result observed, so treat it as a possible item to watch for rather than a dependable purchase. Check local SameDay listings.

Rastelli’s Carver Ham Meal sides
Costco.com listed an online-only Rastelli’s Carver Ham Meal serving eight, with sausage and cranberry stuffing, creamed spinach, scalloped potatoes au gratin, and mac and cheese. These are four side examples within one bundled meal, not four standalone purchases. See the Costco.com meal listing.
Rastelli’s turkey dinner sides
Costco.com’s turkey dinner listing for 8–10 included mashed potatoes, traditional stuffing, Brussels sprouts casserole, green beans almondine, cranberry relish, and gravy. The listing describes a complete online meal kit; verify that it is available for your delivery area and dates before counting on it. See the Costco.com turkey dinner listing.

Simple building blocks for low-effort sides
Baking potatoes
Costco SameDay’s FY26 Thanksgiving page listed baking potatoes. They can anchor a simple baked-potato side, but the listing does not provide a recipe or a comparable cost per serving. Check the FY26 Thanksgiving page.
Cranberry walnut bread
The same seasonal page listed cranberry walnut bread, an easy option to serve alongside the meal without preparing another casserole. The page does not establish a recipe, price-per-serving figure, or consistent availability. Check the seasonal listing.
Rank #3
- One 6 ounce box of Turkey Flavor Stuffing Mix
- Cooks in 5 minutes
- Contains: Soy, Wheat
- Amazon Grocery has all the favorites you love for less. You’ll find everything you need for great-tasting meals in one shopping trip
- Feed your every day with Amazon Grocery
How to compare cost and effort before you shop
The two surfaced SameDay prices do not make a fair six-item affordability comparison: the sources do not provide uniform serving counts, comparable package sizes, or consistent local prices. Bundled meal kits also have a different cost basis from standalone sides. Avoid treating any one item as the universal cheapest choice.
- Prepared item: Check package size, price, local stock, and whether the amount suits your guest count.
- Meal-kit side: Compare the whole package against your needs; its side dishes are bundled rather than independently priced in the cited listings.
- Dietary fit: Check the item’s current ingredient and allergen information. For example, the loaded mashed potatoes listing names dairy ingredients and bacon.
- Shopping channel: Costco SameDay says orders are facilitated by Instacart, while the Rastelli’s listings are on Costco.com. Availability and terms may differ by market and channel.
Costco’s Thanksgiving essentials guide names familiar dishes such as mashed potatoes, stuffing, sweet potato casserole, green bean casserole, and cranberry sauce. That is menu inspiration, not proof that each dish is currently available as a specific Costco product. Read Costco’s Thanksgiving essentials guide.
Rank #4
- One 6 ounce box of Chicken Flavor Stuffing Mix
- Cooks in 5 minutes
- No artificial colors
- Amazon Grocery has all the favorites you love for less. You’ll find everything you need for great-tasting meals in one shopping trip
- Feed your every day with Amazon Grocery
If you would rather make a side at home
A 9-by-13-inch casserole dish is an optional fit for homemade sweet potato gratin or stuffing; Costco’s baking guide describes those uses. Choose this route if you already have the ingredients and want more control over portions or seasoning. See Costco’s baking guide.
Check availability before committing to a menu
Costco’s FY26 seasonal page provides a local SameDay shopping path, but stock and displayed prices can vary. Confirm the listing close to your shopping date, and have a backup if a prepared side is unavailable. For an online meal package, verify the delivery area, timing, and package contents directly on the Costco.com listing.
