When picking out stainless steel mixing bowls, it's important to select a set made with premium, high-grade material. For the uninitiated, the "grade" refers to how strong the steel is and how well it resists heat. The best stainless steel mixing bowls are typically made of 304-grade stainless steel, also referred to as 18/8 or 18/10 (a number that signals the composition of chromium and nickel).
For bowls that are built to last, you'll want to avoid stainless steel in the 400 or 200 series, as it's more susceptible to corrosion and rusting. With 304-grade stainless steel, you can be confident you're getting bowls that are durable, lightweight, and long-lasting.
In addition to evaluating the grade of stainless steel, it's also helpful to look for qualities that make mixing easier. A wide design with plenty of room to stir or toss will help with this, as will curled rims or any other type of lip. A flat bottom is also a big plus, as it adds extra stability and prevents the bowls from sliding all over the place while you're trying to stir. For added convenience, you may even want mixing bowls that come with lids, handles, or silicone bottoms.
Below, is a list of the best mixing bowls on Amazon — all of which feature a flat-bottom design and are made from premium 304-grade stainless steel. They're arranged from the largest quantity set to the smallest, so you can easily find just what you need.
