Why you'll love this recipe
- No marinating: Usually when I make beef fajitas, I need to set aside time for marinating. What I love about using ground beef is that you get the same great flavor without marinating.

- Meal prep friendly: These fajitas are also perfect for meal prepping as you can brown the seasoned ground beef in advance and store in the fridge or freezer!
- Dinner in less than 30 minutes: Prep work is minimal and it takes just 15 minutes to cook the ground beef, peppers and onions!

Ingredient notes
- Ground beef - You'll need 1 pound of ground beef for these fajitas. I normally use lean ground beef (85/15) or extra lean (90/10). (You don't want your fajitas to be too greasy. I use the same approach with my ground beef sliders, and they're definitely not short on flavor)!
- Peppers - Fajitas usually have a mix of bell peppers. This recipe includes red, yellow and green bell peppers, cut into ½-inch slices. You can add some orange bell peppers too, if you prefer.
- Onions - While I went for red onions for these fajitas, you can also use white or yellow. They're also cut into ½-inch slices.
- Fajita seasoning - I used a homemade fajita seasoning for this recipe that consists of chili powder, smoked paprika, cumin, garlic powder, onion powder, cayenne pepper and salt. It's the same seasoning mix I use in this chicken fajita soup recipe.
- Green chilies - This is totally optional, but I like to add a small can of chopped green chilies to the ground beef mixture to add some extra heat.
- Tortillas - Lightly warmed tortillas are a must for fajitas. Flour tortillas are your best option (as opposed to corn tortillas) as they tend to hold up well to all the fajita toppings.
Recipe substitutions
- For leaner fajitas, substitute ground turkey or ground chicken.
- To save a little time, use store-bought fajita seasoning instead of homemade.
- Serve the ground beef mixture on top of rice bowls or salads instead of in tortillas.
How to make fajitas with ground beef
In a small bowl, whisk together the spices for the fajita seasoning.
Heat a skillet over medium heat and the add the ground beef and seasoning. Brown the beef, using a spatula to break it apart into smaller pieces as it cooks.
Once the beef is browned to your liking and no longer pink inside, stir in the green chilies (if using).
Remove the beef mixture from the heat and set aside.
Add oil to a second skillet and heat on high. Add the peppers and onions and sauté for just a few minutes until they start to soften and char slightly.
Serve the ground beef, peppers and onions on tortillas with your desired toppings.

Storage, freezing and reheating
If you have leftovers, store them in an airtight container in the fridge. They should last for 3-4 days.
Reheat leftovers in the microwave or in a skillet on the stovetop before adding them to tortillas.
You can also freeze leftovers, but I suggest freezing the meat separately from the peppers and onions.
Just place them in separate freezer safe containers or bags and store in the freezer for up to 3 months. Defrost in the fridge before reheating.
Expert tips
- Be careful not to overcook the ground beef. You want it browned and cooked to a safe internal temperature of 160F, but you don't want it to end up tough and chewy.
- Make sure your skillet is hot when you add the peppers and onions. This will help char them quickly without overcooking. Remove them from the heat when they just start to soften. If you leave them longer, they'll start to get too soft and soggy.
- If you only have one skillet, just transfer the cooked ground beef to a plate while you sauté the peppers and onions in the same skillet.
- If you have an air fryer, you can also cook your peppers and onions in it using this air fryer peppers and onions recipe.
- The green chilies are optional and add extra heat. Feel free to leave them out if you prefer.
Ground beef fajitas FAQs
The homemade fajita seasoning is a bit spicy, and the addition of chopped green chilies definitely adds some extra heat. If you're sensitive to spice, just leave out the chopped green chilies and use only half of the fajita seasoning. You can always add more seasoning to the ground beef after it's browned.
There are so many topping options! You can top these fajitas with salsa, sour cream, avocado slices, guacamole, cheese, sliced jalapeños, chopped cilantro or a squeeze of fresh lime juice. If I have time to make it, I usually include my creamy jalapeno dip as an optional topping.
Yes, you can use frozen ground beef. Just let it thaw in the fridge overnight before cooking it.
Yes, you can brown the ground beef in advance and slice the peppers and onions. When ready to enjoy, sauté the peppers and onions and reheat the ground beef in a skillet or in the microwave.
Rice is definitely our go-to, but crispy potatoes like my air fryer potato slices, are also delicious. A simple green salad works, especially with a spicy dressing like my jalapeno vinaigrette. You can also go with a side of air fryer tortilla chips and my dairy-free queso!
