What Onions Work Best For Fajitas

Yellow onions are the most popular for making fajitas. They have a sharp but moldy sweet flavor as they break down. White onions can be used as well for replacement. 

Meal Prepping with Fajitas

I made a large batch of shredded meat I used in my Instant Pot. I then tucked into my freezer and used that for meal prepping other meals.

  • Nachos | make a bed of nachos and pile that meat on top! Incredible flavor. I drizzle on sour cream, salsa and guacamole, and cheese. 
  • Burrito | fajita meat in a rolled-up burrito is incredible. I had it once at a Mexican restaurant and it was fantastic. 
  • Burrito Bowl | Serve over rice with all your favorite toppings. Less mess, tasty and a creative way to eat your beef and pepper mixture.

  1. Is there a reason why it would not work to cook these recipes with raw beef or raw ground beef? I know it is possible to put raw chicken just straight in with your other ingredients, but why do you recommend cooking the beef separately first? I am new to Instant Pot and don’t understand. Won’t the flavor be better if you cook the beef from raw with all of the other flavors? Thanks for these freezer dump meals. I think this is the solution to all my problems! hahaha.
