Backyard barbecue season is in full swing, and that means a trip to Costco for cookout supplies. They’re the best place to stock up on everything from paper plates to pork ribs without completely busting your budget. If you’ve got a summer party planned, put these Costco bargains on your shopping list ASAP.

Prices and availability can vary by location and whether you purchase online or in-store.

Instacart

$7.37 per pound

Take a little trouble out of your side dish prep with a premade tortellini pasta salad. It’s in the back near the rotisserie chickens, and it’s made with olives, salami, grape tomatoes, mozzarella pearls, and Italian-style vinaigrette. 

Late July Organic Sea Salt and Lime Tortilla Chips

A bag of Late July Snacks Organic Sea Salt & Lime thin and crispy tortilla chips. The packaging features lime slices and labels showing USDA Organic and Non-GMO Project Verified certifications.
Instacart

$5.55

Of course you need tortilla chips to munch on — and dip — at any kind of party. These Late July chips with a lime seasoning are a fan favorite and go especially well with salsa.

Dixie Paper Plates

A package of Dixie Ultra disposable plates labeled "Ultimate Strength" with Max Shield Technology. The pack contains 186 plates, each 10 inches in diameter. The package highlights features such as soak-proof, microwaveable, and cut-resistant.
Costco

$23.99

Paper plates are much more environmentally friendly than plastic or styrofoam, so make sure you put out a separate recycling bin for these plates at your cookout. There are 186 plates in each package.

Kirkland Signature Beef Hot Dogs

Three packs of Kirkland Signature Beef Hot Dogs, each containing hot dog sausages in clear plastic packaging with black labels and orange text, displayed side by side.
Instacart

$22.69

Do you grab a $1.50 hot dog combo every time you stop at Costco? These are those hot dogs. They’re big, all-beef, and super juicy when you throw them on the grill yourself. There are three 12-packs per package.

Montreal Steak Seasoning

A large container of McCormick Grill Mates Montreal Steak Seasoning with a clear body showing the spice blend, a black lid, and a label featuring steak slices and tomatoes.
Instacart

$5.66

Montreal Steak Seasoning is an absolute classic if you do a lot of grilling. Use it on steak, obviously, but it’s also a great all purpose seasoning for burgers, chicken legs, and even grilled veggies. 

Kirkland Signature USDA Choice Beef Flank Steak

Two raw pieces of beef skirt steak placed side by side on a white foam tray, showing visible grain and marbling.
Instacart

$14.74 per pound

If you’re the kind of person that has to have a steak on the grill (hey, we get it!), the cheapest way to do that with the price of beef so high is with something like flank steak. These are great when marinated and sliced across the grain, especially for something like fajitas. 

Ruffles Potato Chips

A bag of Ruffles Original potato chips with a blue and white design, featuring the Ruffles logo, ridged chips, and a bowl of dip on the front. The words "Original" and "Potato Chips" are displayed.
Instacart

$6.23

Anyone else notice how bad the shrinkflation on potato chips has gotten? Some regular size bags are only 7 ounces now, which is just crazy for the amount we pay. These Ruffles at Costco are still a hefty, party size 28 ounces, thankfully, so you don’t have to buy a ton of smaller bags.

Kirkland Signature Sparkling Water

A 35-pack of Kirkland Signature sparkling water in lime, lemon, and grapefruit essence flavors. The packaging is blue with images of the cans and text highlighting calorie-free, sodium-free, and sweetener-free.
Instacart

$14.40

A large assortment of beverages is a must at a hot summer party, and sparkling water is a refreshing addition. You get 35 cans in this variety pack, with grapefruit, lemon, and lime flavors. 

Bear Mountain BBQ Gourmet BBQ Pellets

A bag of Bear Mountain Premium BBQ Woods Gourmet BBQ hardwood pellets, labeled as 100% natural with balanced sweet smoky flavor, suitable for poultry, seafood, lamb, pork, beef, and veggies, and compatible with all pellet grills.
Costco

$24.99

Pellet smokers are super popular because they’re an easy, mostly hands-off way to create amazing barbecued meats yourself. Many customers swear by these 40-pound bags of pellets for their sweet, balanced flavor. 

Mateo’s Salsa

A 32-ounce jar of Mateo's Gourmet Salsa with a yellow label, featuring red chili peppers and text stating "Uniquely Different," "Medium," "All Natural Ingredients," and "Gluten Free.
Instacart

$7.82

You can’t have a party without a bowl of salsa, and Mateo’s is the brand that won our supermarket salsa taste test. We love that it comes in quarts and it’s way cheaper than buying the small jars at the grocery store. (Pro tip: If you want it hotter, mix in some hot sauce or cayenne pepper!)

Fresh Cut Fruit Bowl

A clear plastic bowl with sections holding cut pineapple, strawberries, green melon, cantaloupe, and red grapes in the center.
Instacart

$13.61

Save a little time (because your time is valuable!) on healthy options at your cookout by getting one of these cut fruit bowls. If you want people to think you put it together yourself, just dump it all in a bowl, mix it together, and voila: fruit salad. 

Kirkland Signature Mini Chocolate Chip Cookies

A clear plastic container filled with chocolate chip cookies, with the lid closed, shown against a plain white background.
Instacart

$11

Everyone wants a little sweet treat at the end of their grilled meal. Grab a container of 60 mini chocolate chip cookies and we guarantee it’ll feed everyone, no matter how many people you’re hosting. 

Heinz Classic Variety Pack

Four Heinz condiment bottles (two Tomato Ketchup Simply, one Barbecue Sauce, one Yellow Mustard) in a "Classic Pack" with a patriotic stars-and-stripes design and the phrase “No artificial preservatives, flavors, or dyes.”
Instacart

$9.07

If you plan on having a few summer cookouts this year, this condiment variety pack is probably a good buy. You get two Heinz ketchups, mustard, and barbecue sauce so you don’t have to think about buying any other condiments until winter. 

Kirkland Signature Red Plastic Cup

A 240-pack of Kirkland Chinet extra strong red plastic cups, labeled "The Big Red Cup," each with an 18 fl oz (532 mL) capacity. The cups are stacked and wrapped in clear plastic packaging.
Instacart

$12.36

If you’re hosting a lot of people — say, for, a graduation party — a huge package of disposable cups will save you cleanup sanity. This package has 240 18-ounce cups, so it’ll probably last you a while — if not multiple summers.

Kirkland Signature Premium Pork Loin Backribs

A vacuum-sealed package of Swift Premium pork loin backribs, showing a large slab of raw pork ribs with visible marbling and a product label on the left side.
Instacart

$3.62 per pound

If beef is out of your budget, your next stop should be the pork section. It’s still pretty inexpensive, and you can get cuts that scream summer like these ribs for what feels like a steal. 

Sweet Baby Ray’s Barbecue Sauce

Two bottles of Sweet Baby Ray’s Barbecue Sauce in a plastic pack, featuring blue labels on the caps and "Barbecue Sauce Award Winning" on the front label of each bottle.
Costco

$7.99

We love Sweet Baby Ray’s classic flavor, with just the right balance of sweet, smoke, and tang. Brush it on your chicken at the end of grilling, or just put it out and let people dip their meats as they please.

A package of Good Foods Organic Chunky Guacamole, 3-pack, featuring images of lime, onion, tomato, and avocado. The label highlights "No Artificial Preservatives" and "USDA Organic.
Instacart

$15.88

Good Foods is one of our favorite guacamole brands, and it’s a real time saver compared to making it from scratch for a large group. This package has three separate 13-ounce cups, so you don’t have to use all of it at once. 

Kirkland Signature Fresh Young Chicken

Two whole raw chickens in clear packaging with blue Kirkland labels reading "Fresh Young Chicken" and "No Added Salt." The chickens are placed side by side.
Instacart

$1.12 per pound

Another inexpensive alternative to beef on the grill is chicken. You can’t get much cheaper than these whole chickens, which make for an impressive sight, whether you cook them over a beer can or halve them for the best grill marks. 

Cowboy Hardwood Lump Charcoal

A 34-pound bag of Cowboy brand oak & hickory hardwood lump charcoal, featuring an illustration of cowboys on horseback and a U.S. flag emblem.
Instacart

$30

You get 34 pounds of charcoal in this giant bag, so you’re unlikely to run out during your cookout. It’s made with oak and hickory for the best smoky flavor. 

Kirkland Signature Grass-Fed Beef Patties

A package of Kirkland 100% Grass-Fed Beef Patties, showing frozen beef patties stacked inside a clear bag. The label highlights "no antibiotics or hormones" and "1/3 lb patties". Net weight is 5 lb.
Instacart

Hamburgers are the classic backyard barbecue fave. These grass-fed beef patties taste richer and beefier than corn fed, and the 20% fat content keeps them super juicy.
