Seared in a hot cast-iron skillet with a savory Dijon-garlic-rosemary crust and roasted until impossibly juicy at 162°F (72°C), this 35-minute turkey tenderloin recipe delivers all the festive aroma of a holiday roast dinner on a busy weeknight or intimate family gathering.
Turkey breast tenderloins—the boneless, skinless inner pectoral muscles nestled beneath the breastbone—are the most tender cut on the entire bird. However, because turkey tenderloin is exceptionally lean with almost zero external fat cover, roasting it naked on a flat baking sheet in a hot oven often dries out the outer layer before the center cooks through.
After testing five different roasting methods in our kitchen, we perfected a two-stage cast-iron skillet-to-oven technique that guarantees butter-soft, juicy medallions every single time. First, we brush the dry-patted tenderloins with an emulsified glaze of Dijon mustard, pure maple syrup (or honey), softened butter, grated garlic, smoked paprika, rosemary, and thyme. Next, we sear all sides in a hot cast-iron skillet for 4 minutes to lock in a golden-brown crust, add a splash of rich poultry bone broth and lemon juice to the pan, and roast at 375°F (190°C) for just 20 to 22 minutes.
Pulling the skillet from the oven the moment an instant-read thermometer reads 160°F–162°F (71°C–72°C) and resting the tenderloins under a loose foil tent for 8 minutes allows gentle carryover heat to bring the center to a safe, succulent 165°F (74°C) while you spoon the buttery garlic-herb pan jus over every carved slice.

Key Ingredients & Why Each One Matters
- Boneless, Skinless Turkey Breast Tenderloins (2 tenderloins, 1.5 to 2 lbs / 680 to 900 g total): Sold in pairs in a vacuum-sealed pack at most supermarkets, each tenderloin weighs roughly 12 to 16 ounces (340 to 450 g) and cooks evenly in 20 minutes.
- Unsalted Butter (4 tablespoons / 56 g, divided): Two tablespoons are softened and mixed into the herb paste, while 2 tablespoons are swirled into the pan jus after roasting.
- Dijon Mustard & Pure Honey or Maple Syrup (1.5 tablespoons / 22 g Dijon + 1 tablespoon / 20 g honey): Dijon mustard acts as a natural emulsifier so the butter-herb paste clings to the turkey, while a touch of honey promotes golden-brown caramelization during the sear.
- Fresh Garlic Cloves (5 cloves / 20 g, finely grated or minced): Infuses both the herb crust and the pan drippings with warm savory depth.
- Fresh Rosemary, Fresh Thyme & Rubbed Sage (1 tablespoon chopped rosemary + 1 tablespoon fresh thyme leaves + 1 teaspoon rubbed sage): The quintessential Thanksgiving and Christmas poultry herb trio.
- Smoked Paprika, Coarse Kosher Salt & Cracked Black Pepper (1 teaspoon smoked paprika + 1.5 teaspoons kosher salt + 1 teaspoon black pepper): Gives the boneless turkey tenderloins a rich golden-amber color and balanced seasoning.
- Avocado Oil or Olive Oil (1.5 tablespoons / 22 ml): Prevents the butter and herbs from scorching during the initial stovetop sear.
- Low-Sodium Chicken or Turkey Bone Broth & Lemon Juice (2/3 cup / 160 ml bone broth + 1 tablespoon / 15 ml fresh lemon juice): Poured around the seared tenderloins right before they enter the oven to create a self-basting garlic butter pan jus.
Start with Dry-Patting & the Dijon-Garlic Herb Paste
Remove the turkey tenderloins from the refrigerator 20 minutes before cooking and pat them thoroughly dry with paper towels. Inspect the underside of each tenderloin—if you see a small white tendon tip peeking out, hold the tendon with a paper towel and slide a sharp paring knife along it to remove it cleanly. Season both tenderloins all over with 1.5 teaspoons (9 g) kosher salt, 1 teaspoon (4 g) cracked black pepper, and 1 teaspoon smoked paprika.
In a small bowl, mash together 2 tablespoons (28 g) softened unsalted butter, 1.5 tablespoons Dijon mustard, 1 tablespoon honey, 5 cloves minced garlic, chopped rosemary, thyme leaves, and rubbed sage. Rub two-thirds of this fragrant herb paste over the seasoned turkey tenderloins, reserving the remaining one-third to brush on top right after searing.
The 162°F Pull Rule & Self-Basting Cast-Iron Jus
Because turkey tenderloin is lean white meat, every degree above 165°F (74°C) squeezes moisture out of the protein fibers. Pulling the roast at 160°F–162°F (71°C–72°C) and transferring it immediately out of the hot skillet onto a warm cutting board lets carryover cooking finish the job gently without drying out a single slice.
3 Pro Secrets for Ultra-Juicy Turkey Tenderloin
- Pour Broth Around—Not Over—the Crust: Add the 2/3 cup bone broth to the side of the cast-iron skillet before roasting so the top herb crust stays crisp while the bottom steams gently in savory broth.
- Use a Digital Instant-Read Thermometer: Insert the probe horizontally into the thickest center of the tenderloin and pull at 160°F–162°F (71°C–72°C).
- Rest 8 Full Minutes Before Carving: Resting under loose foil allows the warm juices to redistribute throughout the medallion fibers.
How to Make Roasted Turkey Tenderloin (Step-by-Step Guide)
- Preheat Oven & Season the Tenderloins (5 Minutes): Preheat your oven to 375°F (190°C). Pat the 2 turkey breast tenderloins (1.5 to 2 lbs / 680 to 900 g total) bone-dry with paper towels and season all sides with 1.5 teaspoons (9 g) kosher salt, 1 teaspoon (4 g) black pepper, and 1 teaspoon (2.5 g) smoked paprika.
- Mix & Apply the Dijon-Herb Butter Paste (5 Minutes): In a small bowl, stir together 2 tablespoons (28 g) softened butter, 1.5 tablespoons (22 g) Dijon mustard, 1 tablespoon (20 g) honey, 5 cloves (20 g) minced garlic, 1 tablespoon chopped rosemary, 1 tablespoon fresh thyme, and 1 teaspoon rubbed sage. Rub two-thirds of the paste over the tenderloins.
- Sear in Cast Iron (4 Minutes): Heat 1.5 tablespoons (22 ml) avocado oil in a 12-inch oven-safe cast-iron skillet over medium-high heat until shimmering. Place both turkey tenderloins in the skillet and sear for 2 minutes per side until a golden-brown crust forms.
- Add Bone Broth & Roast at 375°F (20–22 Minutes): Turn off the stovetop burner. Brush the remaining one-third of the Dijon-herb paste over the top of the seared tenderloins, pour 2/3 cup (160 ml) chicken or turkey bone broth and 1 tablespoon (15 ml) lemon juice around the sides of the skillet, and transfer to the 375°F (190°C) oven for 20 to 22 minutes until the center reads 160°F–162°F (71°C–72°C).
- Rest, Swirl Pan Jus & Carve (8 Minutes): Transfer the roasted tenderloins to a warm cutting board and tent loosely with foil for 8 minutes (internal temp will reach 165°F / 74°C). Set the skillet over medium heat, simmer the pan juices for 2 minutes, and whisk in the remaining 2 tablespoons (28 g) cold butter off the heat. Slice the turkey against the grain into 3/4-inch medallions and spoon the warm garlic-herb butter jus over the top.
Arrange the carved medallions on a warm platter and spoon the emulsified garlic-herb butter jus generously over every slice.
Common Mistakes to Avoid
- Confusing Turkey Breast Tenderloin with a Whole Bone-In Turkey Breast: A bone-in turkey breast weighs 5 to 7 pounds and takes 90+ minutes to roast; boneless turkey tenderloins weigh 12 to 16 ounces each and finish in just 20 to 22 minutes at 375°F (190°C).
- Roasting Past 165°F (74°C) in the Oven: Leaving lean turkey in the oven until it hits 175°F+ dries out the medallions. Always pull at 160°F–162°F and let the 8-minute rest finish the cooking.
- Resting the Turkey Inside the Hot Cast-Iron Skillet: Cast iron retains intense heat for 15 minutes; move the roasted tenderloins onto a wooden board immediately so they don’t overcook in the pan.
- Slicing Parallel to the Muscle Fibers: Always slice perpendicular (against the grain) into 3/4-inch medallions for melt-in-your-mouth tenderness.
Pro Chef Tip: Tuck the Thin Tapered Tips Together
Place the two turkey tenderloins side by side in the skillet with the thick end of one next to the thin tapered tip of the other so they radiate heat evenly and finish at the exact same temperature!
Substitutions & Flavor Variations
- Citrus Cranberry Holiday Glaze: Whisk 2 tablespoons orange marmalade and 1 teaspoon freshly grated orange zest into the Dijon-herb paste for a festive Thanksgiving or Christmas variation.
- Creamy Garlic Herb Pan Gravy: Whisk 1/3 cup heavy cream and 1 teaspoon cornstarch into the skillet broth at Step 5 for a thicker, velvety cream gravy.
- Slow Cooker / Crockpot Turkey Tenderloin: Sear the seasoned tenderloins in a skillet for 2 minutes per side, transfer to a slow cooker with the herb paste and 1/2 cup broth, and cook on LOW for 2.5 to 3 hours until 165°F (74°C).
- Smoky Cajun Butter Rub: Swap the rosemary and sage for 1.5 teaspoons Cajun seasoning and 1/2 teaspoon garlic powder for a bold Southern skillet dinner.
Make-Ahead, Storage & Reheating Guide
Refrigerator Storage: Store sliced turkey tenderloin medallions submerged in the garlic butter pan jus inside an airtight container in the refrigerator for up to 4 days.
Freezer Storage: Freeze cooled slices and pan jus in freezer-safe bags for up to 3 months; thaw overnight in the fridge.
Reheating Without Drying Out: Warm slices gently in a covered skillet over low heat with 3 tablespoons of chicken broth and a pat of butter for 4 minutes just until warmed through.
