Oven-Baked Turkey Tenderloin: Cooking Times & Easy Tips

How Long Should You Cook Turkey Tenderloin in the Oven?

Turkey tenderloin is a fantastic choice for a quick, healthy, and delicious dinner. It’s lean, cooks faster than a whole turkey breast, and pairs well with your favorite sides. But how long should you bake turkey tenderloin in the oven to get that juicy, flavorful result? In this guide, we’ll walk you through everything you need to know about cooking turkey tenderloin in the oven—including temperature tips, step-by-step instructions, and answers to common questions.

What Is Turkey Tenderloin?

Turkey tenderloin is the boneless, skinless part of the turkey breast. It’s an incredibly tender cut because it comes from a muscle that doesn’t get much exercise. This means it’s perfect for quick-cooking methods like roasting or baking. Since it’s so lean, it’s important not to overcook it—otherwise, it can dry out easily.

Recommended Oven Temperature for Turkey Tenderloin

For the juiciest and most flavorful turkey tenderloin, bake it at 350°F (175°C). This temperature allows the meat to cook evenly without drying out.

How Long to Bake Turkey Tenderloin

The typical baking time for turkey tenderloin at 350°F is 25-35 minutes. However, the exact time will depend on the size and thickness of your tenderloins. Here’s a general guideline:

• 1-pound turkey tenderloin: Bake for about 25-30 minutes.
• 1.5-pound turkey tenderloin: Bake for about 30-35 minutes.
• Two smaller tenderloins (about ¾ lb each): Bake for 25-28 minutes.

Always use a meat thermometer to check for doneness. The internal temperature should reach 165°F (74°C) at the thickest part.

Step-by-Step Guide: How to Bake Turkey Tenderloin

1. Preheat your oven to 350°F (175°C).
2. Prepare the turkey: Pat the tenderloin dry with paper towels. Brush with olive oil or melted butter to help seal in moisture.
3. Season generously: Sprinkle with salt, pepper, garlic powder, paprika, dried herbs, or your favorite spice blend.
4. Arrange in a baking dish: Place the seasoned tenderloin(s) in a lightly greased baking dish or on a rimmed baking sheet lined with parchment paper.
5. Bake uncovered: Place in the preheated oven and bake for 25-35 minutes, depending on size.
6. Check temperature: Use a meat thermometer to ensure the thickest part of the tenderloin reads at least 165°F (74°C).
7. Rest before slicing: Remove from the oven and let rest for 5-10 minutes before slicing. This helps keep the juices in the meat.

Tasty Marinades and Seasoning Ideas

While turkey tenderloin is delicious with just salt and pepper, marinades and rubs can add extra flavor. Here are a few ideas:

• Lemon Herb Marinade: Mix olive oil, lemon juice, garlic, rosemary, thyme, salt, and pepper.
• Honey Mustard Glaze: Combine Dijon mustard, honey, olive oil, and a splash of apple cider vinegar.
• BBQ Style: Rub with your favorite barbecue seasoning or slather with BBQ sauce during the last 10 minutes of baking.
• Spicy Kick: Add smoked paprika, chili powder, and a pinch of cayenne for some heat.

Tips for Juicy Oven-Baked Turkey Tenderloin

• Don’t overcook: Always check with a thermometer; overcooked turkey gets dry quickly.
• Baste halfway through: For extra moisture, spoon pan juices over the meat halfway through cooking.
• Let it rest: Resting after baking is key to juicy slices.
• Add veggies: Roast veggies like carrots, potatoes, or green beans alongside the turkey for a complete meal.

Serving Suggestions

Turkey tenderloin goes well with classic sides like mashed potatoes, roasted veggies, rice pilaf, or a simple salad. For a festive touch, serve with cranberry sauce or gravy.

Storing Leftovers

• Refrigerate: Store cooked turkey tenderloin in an airtight container in the fridge for up to 3-4 days.
• Freeze: For longer storage, wrap tightly and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
• Reheat gently: Warm leftovers in the oven at 300°F or in the microwave at low power to prevent drying out.

Frequently Asked Questions (FAQ)

Can I cook turkey tenderloin at a higher temperature?

Yes! If you’re short on time, you can bake at 400°F (205°C) for about 20-25 minutes. Just be extra careful not to overcook—check the internal temperature early.

Should I cover turkey tenderloin while baking?

Usually, it’s best to bake uncovered so you get a nice golden crust. If you notice it browning too fast before reaching temperature, loosely tent with foil.

How do I know when turkey tenderloin is done?

The best way is with a meat thermometer. Insert it into the thickest part; when it reads at least 165°F (74°C), your turkey is safe to eat.

Can I marinate turkey tenderloin overnight?

Absolutely! Marinating overnight will infuse more flavor and help keep it juicy. Even just an hour or two can make a difference.

Is turkey tenderloin healthy?

Yes—turkey tenderloin is low in fat and high in protein. It’s a great choice for anyone looking for a leaner alternative to red meat.

What if my turkey tenderloin is still pink?

Some pinkness doesn’t always mean undercooked—use your thermometer to be sure. As long as it’s reached an internal temp of 165°F, it’s safe to eat.
