A curated list of 10 essential and flavorful items from Costco that make summer BBQs quick, easy, and delicious, perfect for entertaining and crowd-pleasing.

Ingredients

  • Pre-marinated Chicken Thighs (Kirkland brand)
  • Beef Tri-Tip Roast (grass-fed optional)
  • Frozen Jumbo Shrimp (peeled and deveined)
  • Artisan Hamburger Buns
  • Organic Corn on the Cob
  • Fresh Vegetable Kabobs (bell peppers, zucchini, onions)
  • Kirkland Signature BBQ Sauce
  • Seasoning Blend (Costco’s Signature Rub)
  • Coleslaw Mix
  • Fresh Lemons

Instructions

  1. Thaw and prep meats: Remove pre-marinated chicken thighs and beef tri-tip roast from fridge. Thaw overnight or use cold water method if frozen. Pat dry.
  2. Season the beef tri-tip with Costco’s signature rub evenly on all sides for about 2 minutes.
  3. Preheat grill (charcoal or gas) to medium-high (around 375°F). Clean grates with grill brush.
  4. Prepare vegetable kabobs if not pre-assembled by threading bell peppers, zucchini, and onions onto skewers. Brush with olive oil and season with salt and pepper.
  5. Grill chicken thighs skin-side down first for 6-7 minutes per side until internal temperature reaches 165°F. Sear tri-tip 5 minutes per side, then cook indirect heat 20-25 minutes flipping halfway until medium-rare (135°F). Rest tri-tip 10 minutes before slicing.
  6. Skewer shrimp, brush with lemon juice, grill 5-7 minutes turning every 2 minutes until pink and opaque. Grill vegetable kabobs alongside.
  7. Lightly butter artisan hamburger buns and toast on grill for 1-2 minutes until golden and crispy.
  8. Prepare sides: Toss coleslaw mix with dressing or lemon vinaigrette. Boil or grill corn until tender, then butter and salt.
  9. Assemble and serve: Arrange grilled meats, buns, sauces, sides, garnish shrimp with lemon wedges. Encourage guests to build their own plates.

Notes

Keep a spray bottle of water handy for flare-ups. Rest beef tri-tip before slicing to retain juices. Avoid overcooking shrimp to prevent rubbery texture. Toast buns lightly to prevent sogginess. Use two-zone cooking for even grilling. Clean grill grates before cooking.
