Top Tip
Don’t overcrowd the air fryer! Spread the veggies out in a single layer to get that perfect char and crisp-tender texture. Cook in batches if needed—crispy edges make all the flavor difference!
Instructions
Making these sizzling veggie fajitas is as simple as slice, season, and cook! Follow these easy steps for a quick and delicious meal:
Step 1: Prep Your Veggies
First things first—wash your produce! Give those bell peppers, onions, and mushrooms a good rinse. Then, slice the peppers into thin strips, followed by the onions and portabella mushrooms. Try to keep everything about the same size so they cook evenly.
Step 2: Mix & Season
Toss all your sliced veggies into a large bowl. Give them a quick stir to evenly distribute—this way, every bite will have a little bit of everything.
Now, spritz the veggies with a light coat of olive oil (just enough to help the seasoning stick and get that perfect roasted texture). Sprinkle your fajita seasoning over the top and stir again, making sure every piece is well-coated with that smoky, savory goodness.
Step 3: Air Fry to Perfection
Spread the seasoned veggies evenly in the air fryer basket or tray (you might need to cook in batches depending on the size of your air fryer).
Air fry for 10-12 minutes, flipping or shaking the basket halfway through. This helps everything cook evenly and develop that slightly charred, restaurant-style flavor.
Step 4: Serve & Enjoy
Once your veggies are perfectly tender with crispy edges, they’re ready to go! Warm up some gluten-free tortillas, pile on the sizzling fajitas, and load up on your favorite toppings—fresh avocado, salsa, vegan sour cream, or a squeeze of lime for extra brightness.
And just like that, you have a vibrant, flavor-packed meal that’s quick, easy, and totally delicious. Time to dig in and enjoy your homemade veggie fajitas!
Storage
If you have leftovers (lucky you!), here’s how to store them properly so you can enjoy them later:
Refrigeration Instructions
- Let the veggies cool completely before storing. This prevents excess moisture buildup, which can make them soggy.
- Transfer the fajita veggies to an airtight container. A glass or BPA-free plastic container works best.
- Store in the refrigerator for up to 4 days.
Reheating Instructions
- Stovetop: Heat a pan over medium heat and sauté the veggies for a few minutes until warmed through.
- Air Fryer: Reheat at 375°F for 3-5 minutes, shaking the basket halfway for even crispiness.
- Microwave: Heat in 30-second intervals, stirring between each, until warm.
FAQ
Absolutely! If you don’t have an air fryer, you can roast the veggies in the oven at 400°F for 20-25 minutes, stirring halfway through. You can also sauté them in a large skillet over medium-high heat for 8-10 minutes until softened and slightly charred.
Yes! Feel free to add zucchini, cherry tomatoes, or even cauliflower for extra variety. Just keep in mind that softer veggies may cook faster.
The key is not overcrowding the air fryer basket or pan. Cook in batches if needed so the veggies roast instead of steaming. Also, let them cool before storing leftovers to prevent excess moisture buildup.
The spice level depends on your fajita seasoning. If you like extra heat, add cayenne pepper or sliced jalapeños. If you prefer mild fajitas, choose a low-spice seasoning blend.
