Whipping egg whites into stiff peaks is a common baking technique often used in recipes for meringues, soufflés, and angel food cakes. The fluffy, airy texture of fully whipped egg whites can add lightness to your baked goods, but achieving the perfect stiff peaks can sometimes feel like a daunting task. However, with the right tools and techniques, it becomes a manageable and enjoyable process. In this article, we will delve into exactly how long it takes to beat egg whites into stiff peaks using a Kitchenaid mixer, along with tips and tricks for perfect results every time.
Before we delve into the specifics of whipping egg whites, it’s important to understand the science behind it. Egg whites are primarily composed of water and proteins. When you whip them, you’re essentially forcing air into the liquid, causing the proteins to unfold and then reassemble into a network around the air bubbles. This creates a foam that, when whipped continually, becomes increasingly stable and stiff.
A Kitchenaid stand mixer, with its powerful motor and efficient whisk attachment, is an excellent tool for achieving stiff peaks with egg whites. The process is relatively hands-off compared to a hand mixer or a whisk, freeing up your time for other tasks.
To whip egg whites with a Kitchenaid mixer, follow these steps:
Typically, it takes about 5-7 minutes to reach stiff peaks with a Kitchenaid mixer, although this can vary based on the age and temperature of the eggs, the speed of your mixer, and the size of the bowl and whisk.
Stiff peaks are characterized by egg whites that hold their shape without folding over when the whisk is lifted. They should be glossy and smooth, not dry or grainy. If the peaks flop over, the egg whites are at the soft peak stage and need to be whipped a bit longer.

Can I still use a Kitchenaid mixer if my egg whites have a bit of yolk in them?
Unfortunately, no. Even the smallest amount of egg yolk can prevent your egg whites from reaching stiff peaks. The fats in the yolk hinder the proteins in the egg whites from forming the necessary structure.
What speed should I set my Kitchenaid mixer to when whipping egg whites?
It’s best to start at a low speed to break up the egg whites and then gradually increase to high speed. The exact speed can vary based on your specific mixer model, but generally, you’ll want to end up at a speed of 8 or 10.
How can I tell if I’ve overbeaten my egg whites?
Overbeaten egg whites become grainy, dry, and dull. They start to lose their volume and may begin to separate into a watery layer and a clumpy layer. If this happens, it’s best to start over with fresh egg whites.
Achieving stiff peaks with egg whites using a Kitchenaid mixer is a task that requires precision, but with the right approach, it becomes quite simple. Remember to ensure your equipment is clean and free of grease, start your mixer at a low speed and gradually increase, and keep a close eye on the texture of your egg whites. With these tips and tricks, you’ll be well on your way to mastering the art of whipping egg whites to perfection.
