A Cookbook Author's Top 10 Must-Buy Costco Ingredients for Effortless and Flavorful Meals













An experienced cookbook author and a dedicated executive member of Costco reveals her selection of ten indispensable ingredients that serve as the foundation for crafting straightforward yet incredibly tasty meals. Having frequently visited Costco while developing recipes for her acclaimed cookbook, "Big Dip Energy," she leveraged her spending habits to upgrade to an executive membership, recognizing the significant savings. Through this extensive experience, she has meticulously curated a list of cost-effective bulk items that are either everyday essentials for simple cooking or premium additions that elevate ordinary dinners into extraordinary culinary experiences.
Among her top recommendations are S&W Organic chickpeas, an unparalleled value at approximately $1 per can for an eight-pack. These chickpeas are incredibly versatile, perfect for whipping up herby, vegan Green Goddess hummus for social gatherings, or adding a protein boost to salads and soups. They can also be air-fried or oven-roasted for a satisfying, crunchy snack. For those who prefer convenience, Ithaca Hummus stands out as her preferred store-bought brand, celebrated for its creamy texture, pure ingredients, and lack of additives. This substantial container can last for weeks in the refrigerator, making it an excellent base for dips or spreads, especially when paired with fresh vegetables like mini bell peppers, cucumbers, or carrots.
To enhance salads and dips, Kooshy Mambo Italiano's sourdough croutons are a favorite. Their ideal size and robust Italian seasoning, combined with the subtle tang of sourdough, provide an umami-rich flavor. These croutons can also be crumbled over pasta as a substitute for toasted breadcrumbs, mixed into chicken Caesar wraps, or incorporated into homemade snack mixes for an unexpected textural element. For an all-purpose flavor enhancer, Hidden Valley Ranch seasoning powder is a superior choice over its liquid counterpart. This versatile powder can be used in marinades, to season cooked vegetables, or to add zest to morning eggs, offering a wide array of culinary applications.
Meredith Dairy's marinated goat cheese is another highly prized item, once a rare find but now a constant in her fridge since its arrival at Costco. This garlicky, herb-infused cheese adds a touch of indulgence to any dish, from salads and eggs to pasta and toast. The flavored oil remaining after the cheese is consumed can be repurposed for brushing on bread or making homemade mayonnaise. To introduce a spicy kick, Fly by Jing's signature Sichuan chili crisp is a must-have. Its balanced heat, textural complexity, and umami depth, derived from garlic, shallots, ginger, and fermented soybeans, make it an addictive addition to simple meals like white rice with rotisserie chicken.
For sandwiches and Asian-inspired dishes, Kewpie mayonnaise is an essential. Known for its richer egg yolk content and a hint of MSG, it delivers a powerful umami flavor that elevates tuna or egg salads. It also forms the base for delicious dips, such as spicy California-roll guacamole or crab-rangoon dip, and can be easily mixed with hot sauce to create a versatile spicy mayo. Jongga cabbage kimchi offers a delicious way to support gut health. While the author, a Korean American adoptee, didn't grow up with kimchi, she has come to appreciate this brand for its ideal balance of funk, spice, and crunch. This large container is perfect for banchan, Korean pancakes, homemade kimchi-cheese dip, or stir-fries, with a tip to balance its sourness with sugar or stir-frying as it ages.
Bachan's Japanese barbecue sauce is a long-standing favorite, eliminating the need to make homemade teriyaki due to its consistent quality and flavor. Despite its thin consistency, it thickens beautifully when heated, creating a sticky glaze ideal for salmon teriyaki or quickly tossing with rotisserie chicken and instant noodles for a quick meal. Lastly, MiLa's caramelized scallion noodles are a recent but welcome addition to her weeknight repertoire. The flavorful soy-based sauce coats the noodles perfectly, requiring only the addition of protein and vegetables to create a complete and satisfying dish. These curated selections underscore the value and variety available at Costco for both novice and experienced home cooks.
