Recipe for Chicken Tenderloins in Oven: Garlic Butter Baked Bites

My grandmother never wrote down measurements, but her chicken always came out tender and flavorful. This oven method captures that same reliability with a simple garlic butter approach.

High heat ensures the tenderloins cook through without drying out, while the garlic butter baste keeps them moist and aromatic. It takes less effort than stovetop cooking but delivers superior results.

You’ll get perfectly cooked pieces with golden edges and juicy centers every time. The garlic butter infuses each bite with rich, savory depth that elevates the chicken beyond basic baked dishes.

Ideal for weeknight dinners when you want restaurant-quality flavor without the fuss. This technique works for both quick meals and feeding a crowd.

Ingredients for Recipe for Chicken Tenderloins in Oven

Simple ingredients, but the garlic butter makes these tenderloins unforgettable.

The chicken tenderloins are the star here—look for plump, moist pieces (not the dried-out ones at the bottom of the package). Costco has great bulk packs, but any grocery store will do. The butter should be unsalted so you control the seasoning. I always buy European-style for extra richness (the higher fat content browns better).

No fresh garlic? Garlic powder at half the amount works in a pinch, but fresh is best. Out of parsley? Dried parsley at one-third the amount or skip it entirely. The Dijon mustard adds a nice tang—regular yellow mustard works too. For extra flavor, a pinch of cayenne or red pepper flakes adds heat without overpowering.

Bake and serve immediately for best texture. Leftovers keep 3-4 days in the fridge—reheat gently to avoid drying out. Freezes for up to 3 months (thaw overnight before reheating).

Step-by-Step Instructions for Chicken Tenderloins in Oven

This method guarantees tender, flavorful bites with minimal effort and maximum flavor.

Step 1: Season the Chicken Tenderloins

Pat the 1.5 lb chicken tenderloins dry with paper towels—this ensures the seasoning sticks and the skin (if left on) gets crispy. In a small bowl, mix together the 1 tsp kosher salt, 0.5 tsp black pepper, 1 tsp paprika, 0.5 tsp garlic powder, and 0.5 tsp onion powder.

Drizzle the 1 tbsp olive oil over the chicken and rub it all over to coat evenly. Sprinkle the seasoning blend over the chicken, pressing it in gently so it adheres. For extra flavor, add the 1 tbsp Dijon mustard and 1 tbsp lemon juice, rubbing them into the meat as well.

Step 2: Prepare the Garlic Butter

In a small saucepan, melt the 0.5 cup unsalted butter over low heat. Add the 6 cloves minced garlic cloves and cook for 1-2 minutes, stirring constantly, until the garlic is fragrant but not browned. Browning the garlic will make it bitter, so keep the heat low and watch it closely.

Once the garlic is aromatic, remove the saucepan from heat. Stir in half of the 0.25 cup chopped fresh parsley, saving the rest for garnish. This garlic butter will baste the chicken as it bakes, infusing it with rich, savory flavor.

Step 3: Bake the Chicken to Perfection

Preheat your oven to 400°F. Place the seasoned chicken tenderloins in a single layer on a baking sheet lined with parchment paper or foil. This high heat ensures the chicken cooks quickly while staying juicy.

Pour the garlic butter mixture evenly over the chicken, making sure each piece is well-coated. Bake for 15-18 minutes, or until the internal temperature reaches 165°F and the edges are golden brown. If the chicken starts to darken too much, tent the pan loosely with foil.

Step 4: Rest and Serve

Remove the chicken from the oven and let it rest on the baking sheet for 5 minutes. This allows the juices to redistribute, ensuring the chicken stays tender and moist. Sprinkle the remaining fresh parsley over the top for a pop of color and freshness.

Serve the chicken tenderloins hot, with any pan juices spooned over the top. The combination of the crispy exterior, tender interior, and garlicky butter makes these bites irresistible. Pair with your favorite sides for a complete meal.
