Ingredients

  

• 1.25–1.5 lb boneless, skinless chicken breasts (or thighs), sliced into thin strips
• 1 red bell pepper, thinly sliced
• 1 yellow bell pepper, thinly sliced
• 1 green bell pepper, thinly sliced
• 1 large yellow or red onion, thinly sliced
• 2 cloves garlic, minced
• 2 tbsp fresh lime juice (plus extra wedges for serving)
• 2 tbsp olive oil or avocado oil, divided
• 1 tsp kosher salt, divided (adjust to taste)
• 1/2 tsp black pepper, divided
• 2 tsp chili powder
• 1.5 tsp ground cumin
• 1 tsp smoked paprika (or regular paprika)
• 1/2 tsp dried oregano
• 1/4–1/2 tsp red pepper flakes or cayenne (optional, for heat)
• 1/4 cup low-sodium chicken broth or water (optional, for deglazing)
• Fresh cilantro, chopped (optional)
• For serving: warm corn or whole-wheat tortillas, avocado slices or guacamole, pico de gallo, Greek yogurt or light sour cream

Method

 

1. Prep the chicken: Pat the chicken dry with paper towels. In a bowl, toss it with 1 tbsp oil, half the salt and pepper, chili powder, cumin, smoked paprika, oregano, and red pepper flakes if using. Add half the lime juice. Stir to coat and set aside while you prep the vegetables.
2. Heat the pan: Place a large skillet (12-inch) over medium-high heat. Let it get hot before adding anything. This helps you get good color without overcooking.
3. Sear the chicken: Add the chicken in a single layer. Don’t overcrowd—cook in two batches if needed. Sear 3–4 minutes per side until browned and just cooked through. Transfer to a plate and tent loosely with foil.
4. Cook the vegetables: Add the remaining 1 tbsp oil to the pan. Toss in the onions and peppers with the remaining salt and pepper. Cook 5–7 minutes, stirring occasionally, until crisp-tender with some char. Add garlic in the last minute and stir until fragrant.
5. Deglaze (optional): If the pan has browned bits, splash in the broth or water. Scrape with a spatula to release all that flavor.
6. Combine and finish: Return chicken and any juices to the skillet. Toss everything together over medium heat for 1–2 minutes. Turn off the heat and stir in the remaining lime juice. Taste and adjust salt, pepper, or heat.
7. Serve: Sprinkle with cilantro. Serve hot with tortillas and your favorite toppings, or build bowls over rice, cauliflower rice, or greens.

Storage Instructions

• Refrigerate: Cool completely, then store in an airtight container for up to 4 days.
• Freeze: Portion into freezer-safe bags or containers for up to 2 months.

  Thaw overnight in the fridge.

• Reheat: Warm gently in a skillet over medium heat with a splash of water or broth to keep it juicy. Microwave in 45-second bursts, stirring between intervals.
• Meal prep tip: Keep tortillas and cold toppings separate until serving to avoid sogginess.

Why This is Good for You

This skillet packs lean protein to keep you full and support muscle health. Bell peppers deliver vitamin C and antioxidants, while onions and garlic bring prebiotic compounds that support gut health.

Using olive or avocado oil gives you heart-friendly fats. The spice blend adds flavor without heavy sauces or extra sugar.

• High protein, balanced plate: Pair with fiber-rich sides like beans or whole grains for steady energy.
• Lower sodium: Season mostly with spices, lime, and a measured amount of salt.
• Nutrient-dense toppings: Avocado provides healthy fats; Greek yogurt adds extra protein and probiotics.

Pitfalls to Watch Out For

• Crowding the pan: Overcrowding steams the chicken and veggies, leading to pale and soggy results. Cook in batches if needed.
• Overcooking the chicken: Thin strips cook fast.

  Pull them once they’re just done to keep them tender.

• Skipping the heat preheat: A properly hot pan gives you char and flavor without extra oil.
• Heavy-handed with sauces: Bottled sauces can add sugar and sodium. Rely on lime, spices, and fresh toppings instead.

Variations You Can Try

• Chicken thigh version: Juicier and forgiving. Trim extra fat and cook a minute longer per side if needed.
• Veggie-packed: Add mushrooms or zucchini in the last few minutes.

  Keep them crisp to avoid watery veggies.

• Sheet pan method: Toss everything with oil and spices, spread on a sheet pan, and roast at 425°F (220°C) for 18–22 minutes, stirring once.
• Low-carb bowls: Serve over cauliflower rice with avocado, salsa, and shredded lettuce.
• Spicy chipotle twist: Add 1 minced chipotle in adobo and 1 tsp adobo sauce to the chicken marinade.
• Black bean boost: Stir in 1 cup drained, rinsed black beans during the final toss for extra fiber and protein.
• Citrus swap: Try orange juice instead of lime for a mellow, slightly sweet flavor.

FAQ

Can I use a store-bought fajita seasoning?

Yes, but check the label for sodium and sugar. Use about 1.5–2 tablespoons and reduce added salt. You may still want fresh lime for brightness.

What’s the best pan for this?

A large cast-iron or heavy stainless-steel skillet works best.

They hold heat well and help you get that nice char on the chicken and veggies.

How do I keep the vegetables crisp?

Slice them evenly, cook over medium-high heat, and avoid stirring constantly. Give them contact with the hot pan and don’t overcrowd.

Can I make this dairy-free and gluten-free?

It’s naturally dairy-free unless you add cheese or yogurt. For gluten-free, choose certified gluten-free corn tortillas or serve over rice or greens.

What if my chicken is watery?

Pat it very dry before seasoning, and make sure your pan is hot.

If the chicken releases liquid, let it evaporate and continue to sear, or cook in batches.

Is there a way to cut prep time?

Use pre-sliced fajita veggie mixes and thinly sliced chicken cutlets. You can also mix the spices ahead and store them in a small jar.

How can I add more veggies without changing the flavor?

Stir in sliced mushrooms or zucchini during the last 3–4 minutes. They pick up the seasoning and blend right in without overpowering the dish.

What sides work well?

Try warm tortillas, brown rice, cilantro-lime cauliflower rice, black beans, or a simple green salad.

Fresh salsa and avocado round it out nicely.

Can I grill this instead?

Yes. Toss chicken and veggies with oil and spices, then grill in a basket or on skewers over medium-high heat until charred and cooked through. Finish with lime.

How spicy is it?

Mild by default.

Add cayenne, red pepper flakes, or chipotle for heat, or keep it kid-friendly by leaving them out.
