Cooking Tips for Perfect Fajitas
Want your fajitas to turn out amazing? Slice your beef against the grain – this makes each bite super tender! Keep your veggie strips about the same size so they cook evenly. When layering in your air fryer basket, putting the veggies on the bottom helps them catch those yummy beef drippings as everything cooks. A light coat of oil helps everything brown nicely without drying out.
Quick Variations
Not a beef fan? You can swap the tenderloin for chicken breast or shrimp! For vegetarian fajitas, double up on the peppers and add mushrooms or zucchini. Love heat? Mix some cayenne into your fajita seasoning or add fresh jalapeños to your veggie mix. If you prefer a different flavor profile, try a simple mix of salt, pepper, and lime juice instead of fajita seasoning.
Serving Your Fajitas
Set up a fun fajita bar! Warm up your tortillas and put out bowls of fresh toppings. Some family favorites are:
- Diced tomatoes
- Shredded cheese
- Fresh avocado slices
- Chopped cilantro
- Lime wedges
- Sour cream
- Your favorite salsa
Don’t forget to bring the sizzling fajita filling straight from the air fryer to the table!
Storage Tips
Made too much? Keep leftover fajita meat and veggies in an airtight container in your fridge for up to 3 days. When you’re ready to eat, just pop them back in the air fryer for 2-3 minutes at 350°F to warm them up. Store your tortillas separately so they don’t get soggy. These fajitas also freeze well – just pack the filling in freezer bags and use within 2 months!
