Beef Fajitas Recipe
I like to call these beef fajitas "extra budget-friendly" - because you won't want to order your favorite Mexican takeout anymore once you try making them yourself!
My flank steak fajitas are super flavorful and easy to make. You might think the ingredients list looks like a lot - but it isn't. It's all in the seasoning, and it's so straightforward. Anyone can make these fajitas, and trust me, you need to try them!
Family Foodie Tip: I make these indoors on a large skillet, or during the summertime I enjoy pulling out the grill and grilling the steaks!
Steak Fajita Ingredients
- Flank Steak (or Skirt Steak): These cuts are ideal for fajitas due to their rich beef flavor and texture that becomes tender when marinated and cooked properly.
- Olive Oil: Used in the marinade to help tenderize the steak and carry the flavors of the spices, as well as for sautéing the vegetables.
- Lime Juice: Adds acidity to the marinade, tenderizing the steak and providing a bright, citrusy flavor. You can also use lemon juice or even orange juice, but make sure to use fresh juice either way.
- Garlic: Infuses the steak and vegetables with a robust, aromatic flavor that is essential to the fajita seasoning. I like to use a garlic press to make this step easy. You can also use garlic powder. Use ¼ teaspoon per clove.
- Ground Cumin: Offers a warm, earthy taste that's characteristic of fajita seasoning.
- Chili Powder: Gives the fajitas a spicy, smoky flavor, adding some heat to the dish. Cayenne or chipotle powder will work as alternatives.
- Paprika: Adds a sweet and smoky flavor to the marinade and the vegetables, enhancing the overall taste. I recommend using regular paprika, but you can also use sweet, smoked, or hot paprika. Just keep in mind it will alter the flavor.
- Dried Oregano: Contributes an earthy flavor to the marinade that complements the other spices.
- Salt: Essential for seasoning the steak and vegetables, helping to enhance all the flavors in the dish. I recommend using sea salt flakes (my favorite!) or kosher salt, and not table salt.
- Black Pepper: Adds a sharp, peppery note to both the marinade and the sautéed vegetables, balancing the dish. I recommend using freshly cracked black pepper.
- Bell Peppers: Provide a sweet, slightly tangy flavor and a crunchy texture, adding color and nutrition to the fajitas. You can use a mix of bell pepper colors or all one type according to your preferences.
- White Onion: Adds sweetness and depth to the fajitas when sautéed, becoming soft and translucent. You can also use yellow onion, but I recommend avoiding red onion as it's typically too astringent.
- Vegetable Oil: Used for sautéing the vegetables and cooking the steak, ensuring they don't stick to the pan. I recommend a neutral, high smoke point oil.
- Flour Tortillas: Serve as the base for assembling the fajitas, soft and pliable, perfect for wrapping the filling. See my guide on How to Warm Tortillas!

Steak Fajita Toppings
These toppings are totally optional, but can take your fajitas from amazing to so good you wish you'd made extra.
- Sliced avocados or homemade guacamole
- Tomato salsa
- Sour cream or Mexican crema (so good)
- Avocado crema
- Shredded cheese
- Fresh cilantro - but if you don't like cilantro, you can always use parsley instead!
How to Make Fajitas
- In a small bowl, whisk together the olive oil, lime juice, minced garlic, ground cumin, chili powder, paprika, dried oregano, salt, and pepper to make the steak marinade.
- Carefully slice your steak into thin strips (if not already sliced). Place the sliced steak in a resealable plastic bag or a shallow dish. Pour the steak fajita marinade over the steak, making sure it's well coated. Seal the bag, pressing out any excess air, or cover the dish and refrigerate for at least 30 minutes. Marinate for 4 hours up to overnight for maximum flavor.
- In a cast iron skillet over medium heat, add vegetable oil. Once the oil is hot, add in minced garlic. Cook for 2-3 minutes, or until fragrant.
- Toss in sliced onions, and cook for about 2-3 minutes until slightly softened.
- Then, toss in the peppers and cook for an additional 2-3 minutes.
- Season the peppers and onions with cumin powder, chili powder, paprika, dried oregano, salt, and pepper. This is your fajita seasoning mix! Once the peppers and onions are soft and cooked to your desired texture, remove them from the pan and set aside.
- Add additional vegetable oil and the marinated steak to the skillet. Cook on medium-high heat for about 3-4 minutes per side for medium-rare, or adjust the cooking time to your desired level of doneness. Cooking times may vary depending on the thickness of your steak. See my Steak Temperature Chart and use a meat thermometer for proper steak temperatures.
- Add the cooked vegetables back to the skillet and toss everything together.
- Warm your flour tortillas (optional). To serve, place a few slices of the cooked steak in a tortilla and top with the sautéed bell peppers and onions. Add your favorite toppings such as sliced avocado, salsa, sour cream, shredded cheese, and fresh cilantro. Serve and enjoy!
Steak Fajitas Recipe Tips
- Different marinade options: Instead of using fresh lime juice, sometimes I will switch things up with orange juice or pineapple juice, depending on what I have on hand. I also love to throw in some of the fresh zest from the fruit too, for extra flavor!
- Let your steak marinate: Marinate your steak for at least 30 minutes to infuse it with flavor, but overnight is best!
- Slice your steak thin: Slice the steak against the grain for tender bites, making it easier to chew.
- Adjust the heat: Based on your heat preference, adjust the amount of chili powder and paprika you use. You can even add in some cayenne pepper or a sliced chili!
Steak Fajitas FAQ
Flank steak is popular for its texture and flavor, but you can also use skirt steak or sirloin steak. They make excellent choices for beef fajitas! Honestly, though, if you have any leftover steak, you can use it for fajitas. I do this constantly - or I make steak nachos with it!
There are a few key steps to cooking fajita meat so it's tender. Make sure to marinate your steak, especially if you're using a traditional fajita steak like flank steak or skirt steak.
