What’s In This Instant Pot Fajitas Recipe? 

• Skirt steak: A flavorful cut of beef that becomes tender and juicy when cooked in the Instant Pot, making it perfect for fajitas.
• Red peppers: Adds a sweet and slightly fruity flavor to the fajitas, along with a pop of vibrant color.
• Yellow peppers: Another sweet pepper that complements the red pepper, providing both flavor and visual appeal.
• Onion: Sautéed until soft, onions add a savory sweetness that enhances the overall taste of the dish.
• Beef broth: Infuses the steak and vegetables with rich, savory flavor, and helps to tenderize the meat during cooking.
• Fajita seasoning: A blend of zesty spices, including cumin, chili powder, and paprika, that gives the fajitas their signature bold taste.

Substitutions and Additions

• Chicken: If you prefer poultry over beef, you can easily substitute the skirt steak with fresh chicken breast or thighs. The cooking time in the Instant Pot will remain the same, yielding tender and flavorful classic chicken fajitas.
• Vegetarian: For a meatless option, replace the steak with a medley of your favorite vegetables such as mushrooms, zucchini, and bell peppers. You can also add tofu or tempeh as plant-based protein sources.
• Spicy Kick: Love a bit of heat? Add sliced jalapeños or a dash of cayenne pepper to the dish. If you enjoy more intense flavors, you can also use a spicier fajita seasoning blend.
• Tortillas: Serve your fajitas in traditional flour tortillas, or switch things up with corn tortillas, lettuce wraps, or even low-carb alternatives like keto-friendly tortillas.
• Cheese: While not traditionally a part of a steak fajita recipe, a sprinkle of shredded cheese like cheddar, Monterrey Jack, or queso fresco can add a creamy texture and extra layer of flavor.
• Beans: To add more texture and nutritional value, mix in some black beans or pinto beans. They complement the spices well and add a hearty element to the fajitas.
• Lime Juice: Adding a squeeze of fresh lime juice just before serving can elevate the flavors and add a delightful citrusy note.

Recipe Tips

• Use fresh ingredients: Fresh peppers, onions, and high-quality skirt steak will make a noticeable difference in the final flavor of your fajitas.
• Don’t skip the sautéing: Sautéing the onions and peppers in the Instant Pot before pressure cooking helps to caramelize them, adding a depth of flavor to the dish.
• Slice against the grain: When preparing the skirt steak, be sure to slice it against the grain. This will ensure the meat is tender and easy to chew.
• Pre-make the seasoning: Having a batch of homemade fajita seasoning on hand can save you time and ensure you always have the perfect flavor blend ready to go.
• Deglaze the pot: Before sealing the Instant Pot, deglaze the pot with a bit of beef broth to loosen all the delicious browned bits at the bottom. This will enhance the flavor of your fajitas.
• Season to taste: After cooking, taste your fajitas and adjust the seasoning if necessary. A little extra salt, lime juice, or even a dash of hot sauce can perfect the dish.
• Serve immediately: Fajitas are best served hot, straight from the Instant Pot, to maintain their vibrant flavors and tender textures. Toppings such as sour cream, jalapenos, and homemade garden salsa are great choices.

Alternate Cooking Methods 

If you prefer to make your fajitas without an Instant Pot, you can easily adapt the recipe for the oven or a skillet. For the oven method, preheat your oven to 400°F (200°C). Spread the sliced skirt steak, peppers, and onions evenly on a large baking sheet. Drizzle with olive oil and sprinkle with fajita seasoning, then toss everything to coat well. Bake for 20-25 minutes, stirring halfway through, until the steak is cooked and the vegetables are tender. 

For the skillet method, heat a large skillet over medium-high heat and add a splash of oil. Sear the steak strips for 3-5 minutes until browned, then remove and set aside. In the same skillet, sauté the peppers and onions until softened, about 5-7 minutes. Return the steak to the skillet, mix with the vegetables, and cook for an additional 2 minutes. Serve your fajitas hot with your favorite toppings.

Storing Tips 

To store your leftover Instant Pot fajitas, allow them to cool to room temperature before transferring them to an airtight container. Properly stored, they will last in the refrigerator for up to 3-4 days. If you plan to eat them sooner, storing in smaller portions can make reheating easier and more efficient.

You can freeze fajitas for longer storage. Place the cooled fajita mixture in a freezer-safe container or a resealable plastic bag. Be sure to remove as much air as possible to prevent freezer burn. Label the container or bag with the date, and the fajitas will keep in the freezer for up to 2-3 months. When you’re ready to enjoy them, allow the fajitas to thaw overnight in the refrigerator.

Reheating your leftover fajitas is simple and can be done using a variety of methods. For the best results, reheat them on the stovetop. Heat a skillet over medium heat and add a small amount of oil. Add the fajita mixture and stir occasionally until heated through, about 5-7 minutes. 

Alternatively, you can reheat the fajitas in the microwave. Place them in a microwave-safe dish, cover them with a damp paper towel to retain moisture, and heat on high for 1-2 minutes, stirring halfway through. If reheating from frozen, it’s best to thaw them in the refrigerator before using either of the methods mentioned above.

Serving Suggestions 

Complement your Instant Pot steak fajitas with a variety of delicious sides to create a well-rounded and satisfying meal. Here are some ideas to get you started:

• Mexican Rice: This savory side dish, flavored with tomatoes, onions, and spices, pairs perfectly with fajitas. Its rich, slightly tangy taste complements the bold flavors of the steak and vegetables. Another great alternative is cilantro-lime rice.
• Refried Beans: Creamy and hearty, refried beans are a traditional accompaniment that adds protein and texture to your meal. They can be served alongside the fajitas or spread inside the tortilla wraps for an extra layer of flavor.
• Guacamole: Freshly made guacamole, with its creamy texture and vibrant taste, is a favorite. Or go for something a little different with a mango habanero guacamole.
• Pico de Gallo: Fresh pico de gallo is made from diced tomatoes, onions, cilantro, and lime juice adds a zesty, crunchy element. It’s the perfect contrast to the warmth of the cooked fajitas.
• Corn on the Cob: Grilled or boiled corn on the cob, especially when topped with a bit of butter and chili powder, provides a sweet and crunchy side that complements the main dish.
• Salad: A simple green salad with a light vinaigrette can provide a refreshing contrast. Consider a salad with avocado, radishes, and a citrus dressing to keep with the Mexican theme.
• Tortilla Chips and Salsa: Crispy tortilla chips served with a variety of salsas or queso dip can be a fun and tasty side to enjoy along with your fajitas.
