I love how colorful and tasty fajita veggies are, and they make any meal feel special without much effort. This recipe is one of my favorites because it’s simple, full of flavor, and perfect for adding to tacos or just eating on its own. I can’t wait for you to try it and see how easy it is to make these veggies pop with just a few spices.
Most of the ingredients in this recipe are common in many kitchens, like bell peppers and onions. If you don’t usually have cumin, paprika, or garlic powder, you can find them in the spice aisle at the supermarket. These spices add a warm, smoky flavor that really makes the veggies taste amazing, so it’s worth picking them up if you don’t have them yet.

Technique Tip for This Recipe
When you’re cooking the fajita veggies, one of the most helpful moves is learning how to get the bell peppers and onions to cook evenly and get that nice little char without burning. Here’s a simple way to do it:
- Make sure your skillet is hot before you add the olive oil. This helps the veggies start cooking right away.
- Add the sliced bell peppers and onions in a single layer if you can. Crowding the pan can make them steam instead of getting that tasty char.
- Stir the veggies every few minutes, but not too often. Letting them sit for a bit helps them brown and get those yummy flavors.
- Keep the heat at medium-high so the veggies cook through but don’t burn too fast.
Doing this makes the vegetables tender and gives them a little crispy edge, which adds a lot of flavor. When the onions and peppers get a bit of char, it brings out their natural sweetness and makes the whole dish taste better.
I remember the first time I tried this, I kept stirring the veggies all the time because I was worried they’d burn. But that actually stopped them from browning! Once I learned to give them some time between stirs, the fajita veggies turned out way tastier. Also, slicing the peppers and onions about the same size helps them cook evenly, which is a little trick I like to use. It’s a small step that makes a big difference when you’re cooking up these colorful, flavorful veggies!
