Here’s what you’ll need for this fajita recipe:

How to Make Ground Beef Fajitas

Making these fajitas is simple and pretty quick! In just a few steps, you’ll have delicious, ready-to-eat fajitas for a large group of people or for a few meals.

You’ll first need to prepare your vegetables. Slice your onions and peppers into even strips and coat with the olive oil and garlic. You can either bake the vegetables in the oven on a sheet pan or sauté them on the stove.

Bake the the veggies in the oven at 400? for about 15 minutes or until desired tenderness is reached. If sautéing, do so over medium-high heat for about 10 minutes until desired tenderness is reached.

You’ll brown your beef while the vegetables are cooking. Cook the beef all the way through in a pan. Drain any excess fat and add in your fajita seasoning per the packet instructions. Add in the black beans and Rotel tomatoes.

Heat your tortillas in a warmer or in the oven before serving.

Assemble your fajitas with warmed tortillas, meat, vegetables, and the toppings of your choice.

Prep Ahead of Time

You can make the fajitas ahead of time if you don’t want to do all of the prep and cooking the day you serve them.

I will say that the vegetables are the best when served immediately after cooking. However, you can chop and prep them ahead of time and bake them the day of serving. You can also reheat them easily in the oven.

Veggies can be cut and frozen in bags for leftovers and quick prep!

The meat can be cooked ahead of time up to 1-2 days and kept in an airtight container in the fridge. Or you can freeze it into portions for later. Thaw if necessary, then reheat on the stove or in the microwave.

Adjusting the Portions

This fajita recipe is easy to double, triple, fourple, or whatever you need to do. Simply multiply the servings to fit your needs. The recipe makes about 20 fajitas as it is.

You can also stretch some of the more expensive ingredients to make this a really affordable meal to feed a crowd. For example, you can add carrots and zucchini to the bell peppers to make the vegetables go further. You can also add more beans to the ground beef to save some money.

Serving your fajitas with sides like beans and rice will also help fill your plates while remaining easy and affordable. You can really get creative to make this recipe work for a large number of people.
