## Ingredients You’ll Need

Here’s a breakdown of the ingredients you’ll need to create these delicious steak fajitas:

* **Steak:** 1.5 lbs skirt steak or flank steak, trimmed of excess fat. Skirt steak is the traditional choice for its rich flavor and ability to become tender when cooked quickly at high heat. Flank steak is a good substitute, but be sure to slice it thinly against the grain. Other options include sirloin or ribeye, but they are generally more expensive.
* **Onions:** 2 large yellow onions, thinly sliced. Yellow onions provide a good balance of sweetness and savory flavor. You can also use white onions or red onions for a slightly different taste.
* **Bell Peppers:** 3 bell peppers (a mix of colors – red, yellow, and orange), thinly sliced. Using a variety of colors not only makes the fajitas visually appealing but also provides a wider range of flavors and nutrients. Green bell peppers can also be used, but they have a slightly more bitter taste.
* **Olive Oil:** 2 tablespoons. Olive oil is used for sautéing the vegetables and searing the steak. You can also use vegetable oil or avocado oil.
* **Fajita Seasoning:** 2-3 tablespoons (see homemade blend below). Store-bought fajita seasoning works well, but making your own allows you to control the sodium content and customize the flavors. Here’s a great homemade blend:
* 1 tablespoon chili powder
* 1 teaspoon cumin
* 1 teaspoon smoked paprika
* 1/2 teaspoon garlic powder
* 1/2 teaspoon onion powder
* 1/2 teaspoon dried oregano
* 1/4 teaspoon cayenne pepper (optional, for heat)
* Salt and black pepper to taste
* **Lime Juice:** 2 tablespoons, freshly squeezed. Lime juice adds a bright, acidic touch that balances the richness of the steak and vegetables.
* **Tortillas:** Flour or corn tortillas, warmed. Flour tortillas are more pliable and easier to roll, while corn tortillas offer a more authentic flavor. Choose your favorite!

**Optional Toppings:**

* Salsa (pico de gallo, restaurant-style, or your favorite)
* Sour cream or Greek yogurt
* Guacamole or sliced avocado
* Shredded cheese (cheddar, Monterey Jack, or a Mexican blend)
* Chopped cilantro
* Diced tomatoes
* Pickled jalapeños
* Hot sauce

## Equipment You’ll Need

* Large skillet or cast iron skillet
* Cutting board
* Sharp knife
* Mixing bowl
* Tongs

## Step-by-Step Instructions: Making the Best Steak Fajitas

Follow these detailed instructions for perfectly cooked steak, tender vegetables, and a flavor explosion in every bite:

**1. Prepare the Steak:**

* Pat the steak dry with paper towels. This is crucial for achieving a good sear. Moisture is the enemy of browning!
* Place the steak in a large mixing bowl and drizzle with 1 tablespoon of olive oil. Sprinkle generously with fajita seasoning, ensuring both sides are evenly coated. Massage the seasoning into the steak for maximum flavor penetration.
* Let the steak marinate for at least 15 minutes at room temperature, or up to several hours in the refrigerator. The longer it marinates, the more flavorful and tender it will become. If marinating in the refrigerator, bring the steak to room temperature about 30 minutes before cooking.

**2. Prepare the Vegetables:**

* While the steak is marinating, prepare the vegetables. Thinly slice the onions and bell peppers. Try to cut them into roughly the same size so they cook evenly.

**3. Cook the Vegetables:**

* Heat the remaining 1 tablespoon of olive oil in a large skillet (preferably cast iron) over medium-high heat. The skillet should be hot enough that a drop of water sizzles and evaporates quickly.
* Add the sliced onions and bell peppers to the hot skillet. Cook, stirring occasionally, until the vegetables are tender-crisp and slightly caramelized, about 8-10 minutes. Don’t overcrowd the pan, as this will steam the vegetables instead of searing them. If necessary, cook the vegetables in batches.
* Season the vegetables with a pinch of fajita seasoning, salt, and pepper. Stir well to combine.
* Remove the vegetables from the skillet and set aside in a bowl. Cover to keep warm.

**4. Cook the Steak:**

* Increase the heat to high. The skillet should be smoking hot before adding the steak. This is essential for achieving a good sear.
* Carefully place the steak in the hot skillet. Don’t overcrowd the pan. If necessary, cook the steak in batches.
* Sear the steak for 2-3 minutes per side for medium-rare, or longer depending on your desired level of doneness. Use a meat thermometer to ensure accurate cooking. For medium-rare, aim for an internal temperature of 130-135°F.
* Remove the steak from the skillet and place it on a cutting board. Let it rest for at least 5-10 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful steak. Tent it loosely with foil to keep it warm.

**5. Slice the Steak:**

* Using a sharp knife, slice the steak thinly against the grain. Slicing against the grain shortens the muscle fibers, making the steak more tender and easier to chew.

**6. Combine and Serve:**

* Add the sliced steak to the bowl with the cooked vegetables. Toss to combine and coat the steak with the flavorful vegetable juices.
* Squeeze the fresh lime juice over the steak and vegetable mixture. Toss again.
* Serve the steak and vegetables immediately with warm tortillas and your favorite toppings. Let everyone assemble their own fajitas for a fun and interactive dining experience.

## Tips for Perfect Steak Fajitas

* **Choose the Right Steak:** Skirt steak is the traditional choice, but flank steak, sirloin, or ribeye can also be used. Look for a steak that is well-marbled and has a good amount of fat, as this will contribute to flavor and tenderness.
* **Don’t Overcook the Steak:** Overcooked steak is tough and dry. Use a meat thermometer to ensure accurate cooking. Medium-rare (130-135°F) is the ideal doneness for fajitas.
* **Use a Hot Skillet:** A hot skillet is essential for achieving a good sear on the steak and preventing the vegetables from steaming. Make sure the skillet is smoking hot before adding the steak.
* **Don’t Overcrowd the Pan:** Overcrowding the pan will lower the temperature and prevent the steak and vegetables from searing properly. Cook them in batches if necessary.
* **Let the Steak Rest:** Resting the steak after cooking allows the juices to redistribute, resulting in a more tender and flavorful steak.
* **Slice Against the Grain:** Slicing the steak against the grain shortens the muscle fibers, making it more tender and easier to chew.
* **Warm the Tortillas:** Warm tortillas are more pliable and easier to roll. You can warm them in a dry skillet, in the microwave, or in the oven.
* **Get Creative with Toppings:** Fajitas are all about customization. Offer a variety of toppings to suit everyone’s tastes. Some popular toppings include salsa, sour cream, guacamole, shredded cheese, cilantro, and diced tomatoes.
* **Use a Cast Iron Skillet:** If you have one, a cast iron skillet is the best choice for cooking fajitas. It distributes heat evenly and retains heat well, resulting in perfectly seared steak and vegetables.
* **Make Your Own Fajita Seasoning:** Making your own fajita seasoning allows you to control the sodium content and customize the flavors. You can adjust the spices to your liking and create a blend that is perfect for your taste.

## Variations and Substitutions

* **Chicken Fajitas:** Substitute the steak with chicken breasts or thighs. Cut the chicken into thin strips and cook until cooked through.
* **Shrimp Fajitas:** Substitute the steak with shrimp. Cook the shrimp until pink and opaque.
* **Vegetarian Fajitas:** Omit the meat and add more vegetables, such as mushrooms, zucchini, or squash. You can also add black beans or pinto beans for extra protein.
* **Spicy Fajitas:** Add more cayenne pepper or a pinch of chili flakes to the fajita seasoning for a spicier kick. You can also add sliced jalapeños to the vegetables.
* **Different Vegetables:** Feel free to experiment with different vegetables, such as poblano peppers, Anaheim peppers, or poblano peppers.
* **Marinade:** For even more flavor, marinate the steak overnight in a mixture of lime juice, soy sauce, Worcestershire sauce, garlic, and your favorite spices.

## Serving Suggestions

* Serve with a side of Mexican rice and refried beans.
* Make fajita bowls by serving the steak and vegetables over rice with your favorite toppings.
* Use the leftover steak and vegetables to make fajita salads or quesadillas.
* Serve with a pitcher of margaritas or your favorite Mexican beer.

## Make Ahead Instructions

You can prepare several components of this recipe ahead of time to save time on the day you plan to serve it:

* **Make the Fajita Seasoning:** The fajita seasoning can be made weeks in advance and stored in an airtight container.
* **Prepare Toppings:** You can chop the cilantro, dice the tomatoes, and shred the cheese ahead of time and store them in separate containers in the refrigerator.
