• Fajita Seasoning: Blend of spices that adds authentic Mexican flavor and helps tenderize the meat.
• Oil: Helps sear the meat and prevent sticking to the Instant Pot surface.
• Broth: Adds moisture and depth of flavor to the dish, helps create a sauce.

Directions for Flavorful Pressure-Cooked Fajitas

Step 1: Prepare Fajita Seasoning Blend

Create a zesty spice mix by combining chili powder, cumin, garlic powder, paprika, salt, and black pepper in a small bowl. This homemade seasoning will bring incredible flavor to your meat and vegetables.

Step 2: Slice and Season Protein

• Homemade fajita seasoning
• Olive oil
• Freshly ground black pepper

Step 3: Warm Up Your Instant Pot

Activate the Instant Pot’s sauté mode at high temperature. Allow the pot to heat up for 2-3 minutes until it’s sizzling hot.

Step 4: Sear the Protein

Brown the seasoned meat in batches to lock in maximum flavor. Cook each batch for 1-2 minutes per side until a beautiful golden crust develops. Remove and set aside.

Step 5: Chop Colorful Vegetables

• Bell peppers (mix of red, green, yellow)
• Sweet onions
• Optional jalapeños for extra heat

Step 6: Combine Protein and Vegetables

Return the seared meat to the Instant Pot. Add the sliced vegetables and sprinkle with remaining seasoning.

Step 7: Add Liquid and Pressure Cook

• Beef or chicken broth
• Fresh lime juice

Close the lid, seal the valve, and pressure cook on high for 2-3 minutes.

Step 8: Quick Release and Serve

• Fresh cilantro
• Lime wedges
• Sliced green onions

Serving Suggestions:

Serve with low-carb tortillas, cauliflower rice, or enjoy straight from the pot for a delicious keto-friendly meal.

Cooking Tips for Faster, Juicier Results

• Slice Like a Pro: Cutting steak against the grain ensures maximum tenderness, preventing tough, chewy meat in your fajitas.
• Sear for Serious Flavor: Browning the meat before pressure cooking creates deep, rich taste that transforms ordinary fajitas into restaurant-quality bites.
• Squeeze Fresh Citrus: Freshly squeezed lime juice adds bright, vibrant flavor that bottled alternatives simply can't match, elevating the entire dish.
• Timing is Everything: Quick releasing the pressure prevents vegetable mushiness, keeping bell peppers and onions perfectly crisp-tender and full of texture.
• Spice It Up: Customize the heat level by experimenting with extra fajita seasoning or a sprinkle of chili powder to suit your personal taste preferences.

How to Store Your Fajitas Without Drying Out

• Preserve Freshness: Transfer cooled fajitas into vacuum-sealed bags to lock in flavor and prevent freezer burn. This method extends storage life up to 4 months and maintains optimal taste and texture.
• Portion Control: Divide fajitas into individual serving sizes before freezing. Use small, stackable containers or wrap tightly in parchment paper and aluminum foil to prevent moisture loss and freezer damage.
• Quick Reheat: Sprinkle a few drops of water over fajitas before microwaving to restore moisture. Zap in 30-second intervals, stirring between each cycle to distribute heat evenly and prevent drying out.

Flavor Variations That Spice Things Up

• Spicy Southwest Infusion: Amplify the heat by adding diced jalapeños or a pinch of cayenne pepper to the fajita seasoning for a fiery kick that'll wake up your taste buds.
• Herb-Crusted Protein Boost: Incorporate fresh chopped cilantro and a blend of fresh thyme and rosemary into the seasoning mix for an aromatic herbal depth that transforms the classic fajita flavor.
• Mexican Carnitas Style: Swap the steak with pork shoulder and add a splash of orange juice to create a rich, tender meat variation that brings authentic Mexican street food vibes to your Instant Pot.
• Mediterranean Fusion Fajitas: Replace traditional fajita seasoning with za'atar spice blend and use lamb instead of steak, then top with crumbled feta cheese for a cross-cultural culinary experience.
