Air Fryer Bell Peppers and Onions – The Easy Side Dish I Make Almost Every Weekend
Sometimes the simplest recipes end up becoming the most useful. That’s exactly how these Air Fryer Bell Peppers and Onions earned a permanent place in my meal rotation. They’re colorful, flavorful, incredibly versatile, and take almost no effort to prepare.
I first started making them after a friend suggested using the air fryer instead of sautéing vegetables on the stovetop. I’ll admit, I wasn’t convinced at first. Could peppers and onions really get that tender, slightly caramelized texture without a skillet?
Last weekend, I decided to try it while making steak for dinner, and the results were fantastic. The peppers became sweet and slightly roasted, the onions turned golden around the edges, and the whole kitchen smelled amazing. My family loved them so much that we ended up adding them to everything—from sandwiches and wraps to salads and even scrambled eggs the next morning.
Now I make these whenever I’m happy and cooking a big family meal, when I’m stressed and need an easy side dish, or simply on weekends when I want something healthy without a lot of cleanup.
