How to Bake Turkey Tenderloin
This recipe is a lot like our The Best Baked Pork Tenderloin Recipe – you can sear either before or after the oven. For photos, I seared after cooking in the oven, because I had a turkey breast tenderloin that wasn’t staying together well, so I wanted it to firm up through cooking before searing. Technically, you can also skip the sear – but I like to for color and a bit of extra flavor.
Baked Turkey Tenderloin Ingredients
To make this turkey tenderloin, we will need the following ingredients:
- Italian salad dressing (optional marinade) adds acidity, herbs, and oil that tenderize the turkey while infusing it with tangy, savory flavor.
- Extra virgin olive oil helps the seasoning adhere, creates a golden crust, and adds richness as the turkey cooks.
- Sea salt enhances all the natural flavors and helps the tenderloin stay juicy.
- Fresh cracked pepper adds gentle heat and depth.
- Turkey tenderloin is lean, mild, and cooks quickly—absorbing flavors easily while staying tender when well-seasoned.
- Butter (sliced into pats) melts over the turkey for moisture, richness, and browning while carrying herb and garlic flavors.
- Diced garlic brings bold, savory aroma and classic roasted flavor.
- Dried basil adds light sweetness and a soft herbal note.
- Dried oregano contributes earthy, slightly peppery depth for classic Italian flavor.
- Dried thyme offers warm, woodsy fragrance that complements poultry beautifully.
- Dried parsley adds mild brightness and rounds out the herb blend.
- Dried sage provides a traditional poultry-friendly savoriness with a subtle peppery edge.
- Italian herb seasoning blend (2 tbsp) can replace the individual herbs, delivering a balanced mix of classic Mediterranean flavors in one step.
Steps to Bake Turkey Tenderloin
Once we’ve gathered our ingredients, we will use the following process:
Marinate Tenderloins
Marinate turkey tenderloins at least 30 minutes, up to overnight. I like to marinate in a bottle of Italian dressing – or you can use the butter or olive oil herb mix below, as well.
Preheat oven to 350.
Make Garlic Herb Butter
Combine butter, garlic, and herbs in small pot and melt butter while toasting spices. If using olive oil, skip and mix in small bowl.
Season Tenderloin
Season tenderloins well with garlic butter or olive oil mixture.
Optional sear: If tenderloins are firm, pre-sear in a large pan.
Mine were somewhat falling apart, so I seared after roasting.
Place tenderloins on foil or a large sheet of parchment you can fold into a pouch. Add herbs and seasonings and garlic butter.

Fold foil or parchment into a pouch.
Bake 25-35 minutes, until turkey breast tenderloin has reached over 165F.
Optional Sear
As turkey tenderloins finish cooking, you can sear the top and bottom for a bit more flavor and color, which is optional. If you seared before cooking, skip this sear.
Remove tenderloins from pouch, the drippings can be used to make Easy Turkey Gravy.
Rest, Slice, Enjoy!
Let turkey rest for at least 10 minutes after done cooking (from oven or post-sear). Slice into medallions, serve, and enjoy!
Tips and Tricks to Perfect Baked Turkey Tenderloin
Marinate for extra flavor — even 30 minutes in Italian dressing adds noticeable tenderness and brightness; overnight makes it even better.
Pat the tenderloin dry before seasoning so the olive oil and herbs stick and the outside browns instead of steaming.
Use a meat thermometer — turkey tenderloin cooks quickly, and pulling it at 165°F (or even 160°F with a rest) keeps it from drying out.
Let the butter melt slowly during cooking by placing the pats evenly on top; this bastes the meat and deepens the herb flavor.
Mix the garlic with a bit of olive oil before adding if you want it to brown without burning.
Use Italian herb blend when in a hurry — it delivers perfectly balanced flavor without measuring each individual herb.
Add a splash of broth or white wine to the baking dish if you want extra moisture or pan juices to spoon over the slices.
Rest the cooked tenderloin for 5–10 minutes so the juices redistribute and every slice stays tender.
Slice against the grain for the softest texture.
Turn leftovers into meal prep — turkey tenderloin stays moist and reheats beautifully for salads, bowls, wraps, or casseroles.
Baked Turkey Tenderloin FAQs
Yes—just add extra cooking time (usually 10–15 minutes). For best texture and seasoning absorption, thawing first is recommended.
Use a meat thermometer and pull the tenderloin from the oven at 165°F (or 160°F with a resting period). The butter pats and olive oil also help lock in moisture.
No, the recipe is delicious without a marinade—but even a short 30–60 minute soak in Italian dressing adds extra tenderness and flavor.
Absolutely. Use 3x the amount of fresh herbs since they’re milder, and place some under the butter for maximum aroma.
Yes! Cook at 350°F for 22–28 minutes, depending on thickness, turning halfway and checking the internal temp early. Follow our Air Fryer Turkey Breast recipe for more info.
