Storage & Serving Suggestions

Storage Tips

1. Cool It Before Storing…
   Let the chicken and peppers cool to room temperature before packing them up. Nobody wants soggy fajitas from trapped steam!
2. Airtight Containers Are Key…
   Store the cooked chicken and veggies in an airtight container to keep them fresh for up to 4 days in the fridge.
3. Freeze for Later…
   Want to meal prep for the long haul? Freeze the cooked chicken and peppers in a freezer-safe bag for up to 3 months. Just thaw overnight in the fridge and reheat!
4. Skip the Avocado…
   If you’re planning to store, leave out the avocado and toppings. Add those fresh right before serving to keep things creamy and delicious.
5. Reheat Like a Pro…
   Use a skillet to reheat for the best flavor and texture, or microwave in short bursts to avoid drying out.

Serving Tips

1. Go Full Taco Mode…
   Load up your low-carb tortillas or lettuce wraps with the chicken and veggies, then pile on avocado, sour cream, and a sprinkle of cilantro.
2. Serve Family-Style…
   Lay everything out buffet-style and let everyone build their own fajitas. Kids love the DIY approach (and so will you!).
3. Add Extra Zing…
   Serve with lime wedges for a bright, zesty finish or add a drizzle of hot sauce if you’re feeling bold.
4. Pair It Up…
   These fajitas are fabulous on their own but pair beautifully with keto-friendly sides like cauliflower rice or a simple green salad.
5. Leftovers to the Rescue…
   Turn any extras into fajita bowls by skipping the wraps and layering over a bed of spinach or mixed greens for a quick lunch the next day.

Whether you’re meal prepping or serving fresh, these tips will have your chicken fajitas tasting amazing every single time! 🌟

Tips & FAQs

Are Chicken Fajitas Fattening?

Chicken fajitas can be a healthy meal option, depending on preparation. Grilled chicken, sautéed vegetables, and minimal oil contribute to a nutritious dish. However, high-calorie additions like cheese, sour cream, and flour tortillas can increase fat and calorie content. Opting for low-carb tortillas or lettuce wraps and controlling portion sizes can make chicken fajitas a balanced choice.

How to Marinate Chicken for Fajitas

Creating a flavorful marinade is key to delicious chicken fajitas. Combine olive oil, lime juice, minced garlic, and a blend of spices such as cumin, paprika, and chili powder. Coat the chicken thoroughly and let it marinate for at least 30 minutes, or up to 2 hours, to enhance flavor and tenderness.

How to Grill Chicken Fajitas on Charcoal

Grilling chicken fajitas over charcoal imparts a smoky flavor. After marinating, preheat the charcoal grill to medium-high heat. Grill the chicken for 6-8 minutes per side until fully cooked. Simultaneously, grill sliced bell peppers and onions until tender. Serve with your choice of tortillas and toppings.

How Much Salt in Maria’s Fajita Chicken

The salt content in fajita seasoning varies by recipe. Store-bought mixes can contain approximately 250 mg of sodium per serving. To control sodium intake, consider making a homemade seasoning blend without added salt.

Variations & Cooking Methods

Air Fryer Chicken Fajitas

Looking for a crispier texture? Toss the seasoned chicken and peppers in an air fryer at 200°C (400°F) for 8–10 minutes, shaking halfway through.

Grilled Chicken Fajitas

Fire up the grill for smoky flavor. Thread chicken and peppers onto skewers, then grill for 4–5 minutes per side.

Cast Iron Skillet Fajitas

Prefer stovetop cooking? Heat a cast-iron skillet over medium-high heat with 1 tbsp olive oil. Sear the chicken for 3–4 minutes per side, add the peppers, and cook for another 2 minutes.

Meal Prep Chicken Fajitas

Store the cooked chicken and veggies in an airtight container in the fridge for up to 4 days. Reheat in the microwave or a skillet for a quick lunch or dinner.
