Ingredients

• 1.5 pounds chicken tenderloins (about 10–12 pieces)
• 2 tablespoons Cajun seasoning (store-bought or homemade)
• 1 teaspoon smoked paprika (optional for extra smokiness)
• 1/2 teaspoon cayenne pepper (reduce for less heat)
• 1 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1 teaspoon dried thyme or oregano
• 1 teaspoon brown sugar or honey (optional, balances heat)
• 1 teaspoon kosher salt (reduce to 1/2 teaspoon if Cajun blend is salty)
• 1/2 teaspoon black pepper
• 2 tablespoons olive oil (plus more for cooking)
• 1 tablespoon lemon juice or apple cider vinegar
• 1 tablespoon unsalted butter (optional, for finishing)
• Lemon wedges and chopped parsley, for serving (optional)

How to Make It

1. Pat the chicken dry: Use paper towels to remove excess moisture. Dry chicken browns better and gets a nice crust.
2. Mix the spice rub: In a small bowl, combine Cajun seasoning, smoked paprika, cayenne, garlic powder, onion powder, thyme, brown sugar, salt, and black pepper.
3. Coat the tenderloins: Toss chicken with olive oil and lemon juice, then sprinkle the spice mix over the top.

   Rub to coat evenly on all sides.

4. Let it sit: Rest for 10–15 minutes at room temperature. This helps the spices hydrate and the chicken cook more evenly.
5. Heat your pan: Place a large skillet (preferably cast iron) over medium-high heat. Add a thin layer of oil and let it shimmer.
6. Sear in batches: Add chicken in a single layer without crowding.

   Cook 3–4 minutes on the first side until deeply browned.

7. Flip and finish: Turn the tenderloins and cook another 2–3 minutes, until the thickest piece reaches 165°F. Add butter in the last minute and spoon it over for extra richness.
8. Rest and serve: Transfer to a plate and rest 3 minutes. Sprinkle with parsley and a squeeze of lemon.

   Serve hot.

Keeping It Fresh

• Storage: Cool completely, then refrigerate in an airtight container for up to 4 days.
• Reheating: Warm in a skillet over medium heat with a splash of water or broth, 2–3 minutes per side. Or bake at 325°F for 8–10 minutes.
• Freezing: Freeze cooked tenderloins up to 2 months. Thaw overnight in the fridge, then reheat gently.
• Meal prep tip: Slice into strips for quick wraps, salads, or grain bowls across the week.

Benefits of This Recipe

• High-protein, low fuss: Tenderloins cook fast and deliver lean, satisfying protein.
• Budget-friendly: Uses pantry spices and an affordable cut of chicken.
• Flexible flavor: Easily adjust heat and sweetness to match your taste.
• Works with many sides: Rice, roasted veggies, coleslaw, cornbread, or a crisp green salad.
• Great for beginners: Straightforward steps with a forgiving cooking window.

Common Mistakes to Avoid

• Overcrowding the pan: Crowding traps steam and prevents browning.

  Cook in batches for that crisp edge.

• Skipping the pat-dry step: Excess moisture dilutes the spice crust and causes sticking.
• Using only high heat: Too hot and the spices burn. Medium-high gives you color without bitterness.
• Not checking temperature: Tenderloins are thin. Use a thermometer to prevent overcooking past 165°F.
• Seasoning without tasting: Cajun blends vary.

  Start with less salt if your mix is already salty.

Variations You Can Try

• Honey Cajun: Drizzle 1–2 teaspoons of honey in the last minute of cooking for sticky-sweet heat.
• Grilled version: Grill over medium-high heat, 3–4 minutes per side. Great for summer cookouts.
• Air fryer: Air-fry at 400°F for 8–10 minutes, flipping halfway. Lightly spray with oil first.
• Creamy Cajun pasta: Slice cooked tenderloins and toss with al dente pasta, a splash of cream, garlic, and Parmesan.
• Cajun tacos: Serve in warm tortillas with shredded lettuce, avocado, and lime crema.
• Extra smoky: Add a few drops of liquid smoke to the marinade or double the smoked paprika.
• Herb-forward: Swap thyme for fresh chopped parsley and chives at the end for a bright finish.

FAQ

Can I use chicken breasts instead of tenderloins?

Yes.

Slice breasts into 1-inch wide strips for even cooking. Keep the same seasoning and cook time, but check temperature to avoid overcooking.

How spicy is this recipe?

Moderately spicy. For less heat, reduce or omit cayenne and ensure your Cajun seasoning is mild.

You can also add a touch of honey or serve with yogurt sauce to mellow the spice.

What sides go well with Cajun chicken?

Rice, dirty rice, roasted sweet potatoes, corn salad, coleslaw, garlic green beans, or a simple garden salad all pair nicely. Cornbread or buttery mashed potatoes are great too.

Can I marinate the chicken ahead of time?

Absolutely. Marinate up to 8 hours in the fridge.

If using lemon juice or vinegar, avoid marinating overnight to prevent a mushy texture.

How do I prevent the spices from burning?

Use medium-high heat, not full high, and add butter only in the last minute. If your pan starts smoking heavily, lower the heat slightly and give the chicken a little space.

Is there a good store-bought Cajun seasoning?

Yes. Look for blends with paprika, garlic, onion, thyme, and pepper, and check sodium levels.

If it’s very salty, reduce added salt in the recipe.

Can I bake these instead of pan-searing?

Yes. Bake at 425°F on a lightly oiled sheet for 10–12 minutes, flipping once. Broil for 1 minute at the end for extra color.

What sauce pairs well with this?

Lemon-garlic aioli, ranch, chipotle mayo, or a simple lime crema work beautifully.

A squeeze of fresh lemon is often enough.

How do I know when the chicken is done without a thermometer?

The juices should run clear, the center should be opaque and firm, and the fibers should separate easily. Still, a thermometer is the most reliable tool.

Can I make it dairy-free?

Yes. Skip the butter finish and use oil only.

The flavor will still be great, with a slightly less rich finish.
