What Ingredients You Will Need

For this flavorful Costco summer BBQ haul, I focused on quality items that keep things simple but tasty. You might already have a few of these in your pantry, but these Costco picks are about convenience and that extra touch of flavor.

• Pre-marinated Chicken Thighs: Juicy, tender, and packed with a smoky blend of spices. Costco’s Kirkland brand is a favorite here.
• Beef Tri-Tip Roast: Ideal for slicing and serving as a hearty main. Look for grass-fed if you want an extra health boost.
• Frozen Jumbo Shrimp: Peeled and deveined, these are perfect for quick grilling or skewering.
• Artisan Hamburger Buns: Soft but sturdy, these buns hold up to all your sauces and toppings.
• Organic Corn on the Cob: Seasonal and sweet, these make for a classic BBQ side that’s easy to prepare.
• Fresh Vegetable Kabobs: Pre-assembled with bell peppers, zucchini, and onions—great for grilling or roasting.
• Kirkland Signature BBQ Sauce: A smoky, tangy sauce that pairs with just about anything on the grill.
• Seasoning Blend (Costco’s Signature Rub): This mix is a game-changer—perfect for adding extra flavor to meats or veggies.
• Coleslaw Mix: Saves you chopping time and pairs beautifully with grilled items for a cool crunch.
• Fresh Lemons: For squeezing over seafood or adding a burst of brightness to your dishes.

Most of these ingredients are pantry-friendly or freezer-safe, making them great for stocking up ahead of time. Plus, if you want to switch things up, the frozen shrimp can be swapped for chicken sausages, and the tri-tip roast can go for a brisket cut if you’re feeling adventurous. I’ve found that sticking with quality, versatile items makes BBQ planning less of a headache and more enjoyable.

Equipment Needed

While the star of the show is definitely the flavorful food, having the right tools makes your summer BBQs smooth and stress-free. Here’s what I recommend grabbing or checking you have on hand:

• Grill (Gas or Charcoal): Both work well, but I personally prefer charcoal for that smoky flavor. If you don’t have one, a quality electric grill can do the trick.
• Long-handled Tongs: Essential for flipping meats without burning your fingers.
• Meat Thermometer: Nothing beats perfectly cooked meat, and this tool helps avoid guesswork.
• Large Mixing Bowls: For tossing salads, marinating meats, or mixing BBQ sauces.
• Skewers: Metal or bamboo; soak bamboo ones in water to prevent burning.
• Grill Brush: For cleaning grates—trust me, a clean grill makes a huge difference in flavor.
• Serving Platters and Utensils: Big enough to hold your delicious spread and easy to pass around.

If you want to keep it budget-friendly, many of these items can be found at Costco itself or at local dollar stores. I’ve had my trusty set of tongs for nearly a decade, and the meat thermometer was a gift that changed my BBQ game forever. Remember to keep your equipment clean and well-maintained; a sticky grill or rusty tongs can really put a damper on the fun.

Preparation Method

1. Thaw and Prep Meats (20-30 minutes): Remove the pre-marinated chicken thighs and beef tri-tip roast from the fridge. If frozen, thaw overnight or use the cold water method (sealed in a bag, submerge in cold water, changing every 30 minutes). Pat dry to get a good sear.
2. Season the Beef Tri-Tip: Even though it’s high-quality, I like to add an extra sprinkle of Costco’s signature rub before grilling. Rub evenly on all sides for about 2 minutes.
3. Preheat Your Grill (15 minutes): Light your charcoal or preheat your gas grill to medium-high (around 375°F/190°C). Clean the grates with your grill brush to avoid sticking.
4. Prepare Vegetable Kabobs: If not pre-assembled, thread bell peppers, zucchini, and onions onto skewers. Brush lightly with olive oil and sprinkle with salt and pepper.
5. Grill Chicken and Beef: Place chicken thighs skin-side down first for a crisp finish. Grill chicken for about 6-7 minutes per side, or until juices run clear (internal temp 165°F/74°C). For tri-tip, sear on both sides for 5 minutes each, then move to indirect heat and cook for 20-25 minutes, flipping halfway, until medium-rare (135°F/57°C). Let rest 10 minutes before slicing.
6. Grill Shrimp and Kabobs (5-7 minutes): Skewer shrimp and brush with lemon juice before placing on the grill. Turn shrimp every 2 minutes until pink and opaque. Grill vegetable kabobs alongside for a smoky char.
7. Toast Buns: Lightly butter the artisan hamburger buns and toast them on the grill for 1-2 minutes until golden and slightly crispy.
8. Prepare Sides: Toss coleslaw mix with your favorite dressing or make a quick lemon vinaigrette. Boil or grill corn on the cob until tender, then slather with butter and sprinkle with salt.
9. Assemble and Serve: Lay out your grilled meats, buns, sauces, and sides. Garnish shrimp with fresh lemon wedges. Encourage guests to build their own plates and enjoy!

Pro tip: Keep a spray bottle of water handy for unexpected flare-ups on the grill. And don’t forget to rest the beef tri-tip—it’s the key to juicy slices. I once ruined a roast by slicing it too soon (lesson learned). Also, keep an eye on shrimp; they cook fast and can get rubbery if overdone.

Cooking Tips & Techniques

Summer BBQs are as much about technique as they are about ingredients. Here are some of my best tips to get consistent, flavorful results every time:

• Marinate or Season Ahead: Even with pre-marinated meats, adding your own rub or marinade a few hours before grilling deepens flavor.
• Use Two-Zone Cooking: Set up your grill with a hot zone for searing and a cooler zone for slower cooking. This helps avoid burning and ensures even doneness.
• Don’t Overcrowd the Grill: Give each piece enough space for air to circulate. Crowding causes steaming instead of grilling.
• Check Internal Temps: I can’t stress this enough. Use a meat thermometer to avoid guessing and overcooking. Chicken should hit 165°F/74°C, and beef tri-tip tastes best medium-rare at 135°F/57°C.
• Rest Your Meat: Let grilled meats rest at room temperature for 5-10 minutes before slicing to lock in juices.
• Keep Sauces on the Side: Brush BBQ sauce on meats during the last few minutes of grilling or serve on the side to prevent burning.
• Clean the Grill Between Uses: A quick brush before cooking helps prevent flare-ups and keeps flavors pure.

One time, I forgot to check the grill temp and ended up with charred kabobs and undercooked chicken—a rookie mistake I won’t repeat. Also, multitasking is key: while the tri-tip is resting, grill shrimp and buns to save time and keep everything hot. These little timing moves make all the difference when feeding a hungry crowd.

Variations & Adaptations

One of the best things about this Costco BBQ list is its flexibility. Here are some ways to tweak it for different tastes and needs:

• For a Vegetarian BBQ: Swap out meats for plant-based options like marinated tofu or veggie burgers. The vegetable kabobs and corn on the cob remain perfect staples.
• Spicy Kick: Add a dash of cayenne or chipotle powder to the seasoning blend or choose a hot BBQ sauce to amp up flavor.
• Low-Carb Option: Replace hamburger buns with large lettuce leaves or grilled portobello mushrooms for a bun-less burger experience.
• Seafood Focused: Double down on shrimp and add salmon filets or scallops, seasoned with lemon and herbs.
• Personal Twist: I once swapped out the tri-tip for a Costco brisket roast, slow-grilled and sliced thin for a Southern-style feast. It was a hit and made the day feel extra special.

Feel free to customize based on what your guests like or what’s fresh that week. The great thing about this list is that it’s a starting point—not a rigid plan.

Serving & Storage Suggestions

The way you serve and store your BBQ goodies can really shape the experience:

• Serve Warm and Fresh: Most grilled items taste best hot off the grill. Keep cooked items covered with foil to retain heat if you’re serving buffet-style.
• Presentation: Arrange grilled meats and veggies on large platters garnished with fresh herbs or lemon wedges for a vibrant, inviting spread.
• Complementary Sides: Pair with simple sides like potato salad, baked beans, or a crisp green salad to balance the smoky flavors.
• Storage: Leftovers should be cooled to room temperature, then refrigerated in airtight containers within two hours. Most grilled meats keep well for 3-4 days.
• Freezing: If you want to save some for later, wrap meats tightly in foil and freezer bags; they’ll last up to 3 months.
• Reheating: For best flavor, reheat meats gently in the oven at 300°F (150°C) covered with foil to prevent drying out. Avoid microwaving if possible—it tends to make grilled foods rubbery.
• Flavor Development: Some BBQ sauces and marinades deepen in flavor overnight, so don’t hesitate to prep a day ahead for even tastier results.

Nutritional Information & Benefits

This flavorful Costco BBQ list balances indulgence with nutrition, thanks to a mix of protein, fresh veggies, and whole ingredients. Here’s a rough idea of what you’re getting:

• Protein-Packed: Chicken thighs, beef tri-tip, and shrimp provide essential amino acids for muscle repair and energy.
• Vitamin-Rich Veggies: Corn, peppers, and zucchini offer fiber, antioxidants, and vitamins A and C.
• Healthy Fats: Using olive oil on kabobs and moderate butter on corn adds good fats that support heart health.
• Low in Processed Sugars: Costco’s BBQ sauces are flavorful but watch for sugar content; you can always opt for homemade dressings.

This list can easily fit into gluten-free or low-carb diets by swapping buns or omitting certain sides. Just keep an eye on marinades for hidden allergens like soy or gluten. Personally, I appreciate that these ingredients let me enjoy a delicious BBQ without feeling weighed down afterward—a win-win for summer gatherings.
