The chicken tenderloins are the foundation here. Look for uniform size at your butcher or grocery store—this ensures even cooking. Costco often carries pre-trimmed tenderloins that save prep time. For the barbecue sauce, Stubb’s Original or Sweet Baby Ray’s deliver consistent smoky-sweet flavor. Avoid sauces with high fructose corn syrup if possible, as they can burn more easily under high heat.
No barbecue sauce on hand? Ketchup plus a dash of molasses and smoked paprika gets you close. Out of Worcestershire? Soy sauce with a pinch of sugar works in a pinch. The liquid smoke is optional but adds authentic depth—just don’t overdo it. For a spicier kick, swap smoked paprika for chipotle powder. The brown sugar can be replaced with honey if needed.
Marinated chicken keeps in the fridge for up to 24 hours before cooking. Leftovers stay fresh for 3-4 days and reheat beautifully. The sauce tends to thicken when stored, so a splash of water brings it back to life.

Step-by-Step Instructions for Baked Barbecue Chicken Tenderloin
Here’s the method. Straightforward, tested, works every time.
Step 1: Season the Chicken Tenderloins
Pat the 1.5 lb Chicken Tenderloins completely dry with paper towels. This ensures the seasoning adheres properly and promotes even browning. In a small bowl, combine the 1 tsp Garlic Powder, 1 tsp Onion Powder, 1 tsp Smoked Paprika, 1 tsp Kosher Salt, and 0.5 tsp Ground Black Pepper.
Rub this spice blend evenly over all surfaces of the chicken tenderloins, pressing gently to help it stick. The smoked paprika and liquid smoke will create that authentic barbecue depth without a smoker. For extra flavor, I always let the seasoned chicken sit at room temperature for 10-15 minutes while the oven preheats.
Step 2: Prepare the Barbecue Marinade
In a medium bowl, whisk together the 1.5 cups Barbecue Sauce, 2 tbsp Olive Oil, 1 tbsp Apple Cider Vinegar, 1 tbsp Worcestershire Sauce, 2 tbsp Brown Sugar, and 0.5 tsp Liquid Smoke until the brown sugar fully dissolves.
The vinegar and Worcestershire balance the sweetness of the barbecue sauce while adding complexity. The olive oil helps the sauce cling to the chicken, and the liquid smoke enhances the smoky profile. Taste the marinade and adjust seasoning if needed—though the barbecue sauce should already be well-balanced.
Step 3: Coat and Bake the Chicken
Preheat your oven to 375°F and line a baking sheet with parchment paper for easy cleanup. Arrange the seasoned chicken tenderloins on the prepared sheet. Brush half of the barbecue marinade generously over all sides of the chicken, coating it completely.
Bake for 20 minutes, then remove the pan from the oven. Flip the tenderloins and brush with the remaining marinade. Return to the oven and bake for another 10-15 minutes until the chicken reaches an internal temperature of 165°F and the sauce has begun to caramelize at the edges.
Step 4: Rest and Serve
Transfer the baked chicken to a serving platter and let it rest for 5 minutes. This allows the juices to redistribute throughout the meat, ensuring every bite stays moist and tender. The sauce will thicken slightly as it cools, creating a glossy glaze.
Serve the chicken tenderloins hot, drizzled with any pan juices. The meat should be juicy and tender with a slightly sticky, smoky-sweet exterior. For presentation, I like to garnish with fresh parsley or sesame seeds, though these aren’t essential to the dish’s success.
Pro Tips For Making Baked Barbecue Chicken Tenderloin
- Preheat the Pan: I learned this the hard way—sear the tenderloins in a screaming hot pan for 2 minutes per side before baking. That crust keeps the juices in and prevents the sauce from making the meat soggy.
- Dry the Chicken: Pat those tenderloins bone-dry with paper towels before seasoning. Sounds tedious, but it’s the only way to get a proper sear instead of steamed chicken.
- Skip the Early Sauce: Resist the urge to slather on the barbecue sauce before baking. Brush it on during the last 10 minutes only, or it’ll burn and turn bitter.
- Thin the Sauce: Mix the barbecue sauce with a splash of apple cider vinegar before brushing—about 1 tablespoon per ½ cup. It spreads easier and cuts through the richness.
Make-Ahead Tips for This Recipe
Marinade Prep Ahead
Mix the barbecue sauce, olive oil, vinegar, and spices up to 24 hours before cooking. Store in an airtight container in the fridge. This lets flavors meld beautifully while saving you time on busy days. I always prep this the night before local BBQ competitions. 💡
Chicken Storage
Season and coat the chicken with half the marinade up to 12 hours ahead. Keep it in a sealed container at 40°F or below. The acid in the vinegar helps tenderize the meat while keeping it safe to eat.
Partial Cook Method
Bake the chicken for the initial 20 minutes, then refrigerate it uncovered. Finish cooking the next day by adding the remaining marinade and baking at 375°F for 10-15 minutes. This works great for meal prep Sundays. ⏰
Sauce Separation
Make extra marinade and store it separately in the fridge for up to 5 days. Use it to baste the chicken just before serving or as a dipping sauce. The flavors intensify over time, making it even more delicious.
Freezing Instructions
Cook the chicken fully, let it cool, then freeze in airtight containers for up to 3 months. Reheat from frozen in a 350°F oven for 25-30 minutes. I always add a splash of water to keep it moist. ❄️

Frequently Asked Questions
Can I use chicken breasts instead of tenderloins?
Yes, but adjust the cooking time to 25-30 minutes total. Chicken breasts are thicker and need more time to reach 165°F internally. Pound them to even thickness for best results.
Why do I need to let the chicken rest?
Resting for 5 minutes allows juices to redistribute, keeping the meat moist. Skipping this step can cause dryness as juices escape when cut too soon.
What if my sauce burns during baking?
Tent the pan with foil after the first 20 minutes to prevent over-browning. Use a lower oven rack and check frequently near the end.
Can I make this spicier?
Add 1/2 tsp cayenne or 1 chopped jalapeño to the marinade. For heat lovers, brush with hot sauce before the final bake.
