12 Costco Finds That Make Thanksgiving Prep So Much Easier

Thanksgiving prep doesn’t have to mean multiple grocery runs or sky-high food bills. With a little planning, Costco can cover nearly everything you need—while keeping quality high and costs low. From produce and olive oil to nuts and charcuterie, these Costco Thanksgiving essentials make hosting simpler, healthier, and way less stressful.

1. Stuffing Mix & Ingredients

Costco has all the staples for stuffing success—large bags of organic bread cubes, low-sodium broths, and pre-chopped onions and celery. You can even grab Pacific Foods Organic Stuffing Mix as an easy base to customize with herbs and veggies.

Tip: Mix in sautéed mushrooms, apples, or pecans for extra flavor and texture without relying on heavy butter.

2. Fresh Green Beans

Those two-pound bags of crisp green beans are perfect for a lighter, fresher Thanksgiving side. Steam or roast them, then toss with olive oil, lemon zest, and toasted almonds.

Tip: Skip the canned soup topping—fresh green beans with a quick homemade sauce taste brighter and contain less sodium.

3. Sweet Potatoes

Grab a big bag of Kirkland Signature Organic Sweet Potatoes for mashed, roasted, or casserole dishes. They’re naturally sweet and rich in fiber and vitamin A.

Tip: Roast them with olive oil and cinnamon instead of sugar for a wholesome, caramelized flavor.

4. Charcuterie Board Essentials

From prosciutto and salami to crackers and olives, Costco’s bulk packs make building a holiday charcuterie board easy and affordable. You can even skip the assembly altogether and grab one of their ready-to-eat charcuterie boards, complete with curated meats, cheeses, and accompaniments

Tip: Add grapes, pomegranate seeds, or sliced apples for color and balance.

5. Mixed Nuts

Whether you’re serving pre-dinner snacks or baking something delicious, Kirkland Signature Extra Fancy Mixed Nuts are a cost-effective way to stock up on all sorts of nuts.

Tip: Toast lightly before serving to bring out natural oils and deepen flavor.

6. Olive Oil

Costco’s olive oil selection—especially Kirkland Organic Extra-Virgin—is a secret weapon for heart-healthy cooking.

Tip: Use olive oil instead of butter in stuffing, mashed potatoes, or roasted veggies for rich flavor and better fats.

7. Pre-Cooked Turkey Breast or Rotisserie Chicken

Hosting a smaller crowd? Costco’s Oven-Roasted Turkey Breast and famous Rotisserie Chickens are lifesavers.

Tip: Use leftover turkey or chicken for next-day soups or grain bowls to minimize food waste.

8. Frozen Veggie Medleys

Keep Kirkland Organic Brussels Sprouts or Cauliflower Rice on hand for quick sides.
Tip: Roast straight from frozen—no thawing needed—and toss with olive oil and herbs for crispy edges.

9. Sparkling Water & Better-for-You Drinks

Stock up on Spindrift, San Pellegrino, or Olipop multipacks to give guests festive, low-sugar drink options.

Tip: Create a DIY drink bar with citrus slices, cranberries, and herbs for a naturally flavored mocktail station.

10. Spices & Broth

Stock up on organic spices and Kirkland Organic Chicken Stock—they’ll last long after Thanksgiving.

Tip: Keep fresh herbs like rosemary and thyme in a small glass of water in the fridge; they’ll stay perky for days.
