Quick Answer
Costco carries three main meatball products under the Kirkland Signature label: Italian-style beef and pork meatballs (about $14.99 for 64 oz), Italian-style turkey meatballs (about $13.99), and teriyaki-flavored beef meatballs (about $14.99). All three are fully cooked and just need to be heated through — in the oven at 350°F for 15–20 minutes, on the stovetop in sauce, or in a slow cooker. Italian meatballs shine in spaghetti, subs, and soup; teriyaki meatballs are great over rice or as an appetizer with toothpicks.
The Kirkland Signature meatball lineup at Costco is a weeknight dinner cheat code. Three different varieties — Italian beef and pork, Italian turkey, and teriyaki-glazed beef — sit in the freezer section ready to anchor a pasta dinner, a meatball sub, or a saucy appetizer platter. Every single one is fully cooked, which means you're just heating, not cooking. The 64-ounce bags clock in at roughly 80 meatballs each, making them cost-effective for feeding families or meal prepping for the week. Each variety has its own best applications: the Italian meatballs have the classic beef-and-herb flavor profile that plays well with marinara and on hoagie rolls, while the teriyaki meatballs bring a sweet, savory soy-ginger glaze that pairs perfectly with steamed rice and vegetables. This guide covers what to buy, how to heat Costco meatballs without drying them out, and eight recipes — from quick weeknight spaghetti to slow cooker grape jelly meatballs — that make the most of every bag.
What Meatball Products Does Costco Sell?
Costco typically carries three Kirkland Signature meatball varieties: Italian-style beef and pork meatballs, Italian-style turkey meatballs, and teriyaki beef meatballs, all sold in 64 oz bags. The Italian beef and pork variety is the most versatile — seasoned with garlic, onion, and Italian herbs, they work in pasta, subs, soups, and appetizers. The turkey meatballs are a leaner alternative with a similar flavor profile, ideal for those watching saturated fat intake. The teriyaki meatballs come pre-glazed with a sweet soy-ginger sauce and are best used in Asian-inspired dishes or served as party appetizers. Product availability can vary by location and season, so check the freezer aisle near the prepared proteins.
How to Heat Costco Meatballs
Because Costco meatballs are fully cooked, you have several heating options. Oven method: spread frozen meatballs on a rimmed baking sheet and bake at 350°F for 15–20 minutes, or until heated through to an internal temperature of 165°F. Stovetop method: add meatballs directly to a simmering sauce in a large skillet or saucepan and heat covered for 10–15 minutes, turning once — this is the best method for keeping them moist, since they absorb some of the sauce. Slow cooker method: place frozen meatballs in the slow cooker with your sauce of choice, set to low for 3–4 hours or high for 1.5–2 hours. Microwave in a pinch: heat 6 meatballs on a microwave-safe plate covered with a damp paper towel for 2–3 minutes at full power.
The Best Meatball Recipes
Italian Costco meatballs are at their best in classic spaghetti and meatballs — just simmer them in a quality marinara (Rao's from Costco is a natural pairing) for 15 minutes while the pasta boils. Meatball subs are another top use: heat meatballs in sauce, pile onto hoagie rolls, add provolone, and broil for 2–3 minutes until the cheese bubbles. For a crowd-pleasing appetizer, slow cooker grape jelly meatballs require just two ingredients — a jar of grape jelly and a bottle of chili sauce — and make an absurdly addictive party snack. Meatball soup is another winner: add Italian meatballs to a pot with chicken broth, canned diced tomatoes, white beans, and spinach for a 20-minute dinner.
How to Use Teriyaki Meatballs
Kirkland teriyaki meatballs are among the most versatile items in the Costco freezer section. The most obvious use is teriyaki meatball bowls: heat the meatballs in a skillet, serve over steamed white or jasmine rice, and top with sliced green onions and sesame seeds. They're equally excellent as an appetizer — serve them in a slow cooker on the warm setting with toothpicks and extra teriyaki sauce on the side. For a 20-minute weeknight dinner, stir-fry frozen teriyaki meatballs with broccoli, snap peas, and bell peppers in a hot wok, then serve over noodles or rice. The pre-applied glaze means no additional sauce is needed, though a drizzle of sriracha or rice vinegar can brighten the dish.
