Make this easy turkey tenderloin marinade with maple syrup, Dijon mustard, and garlic for juicy, flavorful turkey every time.
Turkey tenderloins are a lean, versatile cut that cooks quickly and stays tender. Since discovering them, I’ve added several simple preparations to my regular rotation — from herb-crusted for holidays to everyday baked tenderloins rubbed with spices. This maple-mustard marinade is one of my favorites: sweet, tangy, and easy to throw together with pantry staples.
The marinade also works beautifully as a glaze when baked, and it makes perfect sheet-pan meals when you roast carrots, apples, or other seasonal vegetables alongside the turkey. It’s great for oven baking, the air fryer, or the grill.
If you’re new to turkey tenderloins, they’re boneless, skinless pieces from the turkey breast. They typically come two per package, cook fast, and make excellent leftovers for sandwiches or salads.
Ingredients
This simple marinade adds bold flavor while keeping the meat moist. Here’s what you need and why it works:
- Olive oil helps carry and distribute flavor. Canola or avocado oil work fine as substitutes.
- Maple syrup provides sweetness and helps form a glaze. Brown sugar plus a tablespoon of water is an alternative; low-carb sweeteners work for keto adaptations.
- Stone ground Dijon mustard (whole grain Dijon) adds tang and texture and helps tenderize the meat. Regular Dijon or yellow mustard can be used if needed.
- Dried thyme complements turkey nicely; rosemary or oregano are good swaps. If using fresh herbs, use three times the amount called for dried.
- Garlic powder (or minced fresh garlic) boosts savory flavor. Onion powder can be used in a pinch.
- Salt and black pepper to season. Adjust salt if your tenderloins came in a brine.
- Turkey tenderloins — boneless, skinless turkey breast tenderloins (about 1.5 pounds in this recipe). The marinade also works for turkey breasts, cutlets, chicken breasts, or pork tenderloin.
Marinade yield: About 10 tablespoons, enough for up to 2 pounds of meat. This recipe typically leaves about half the marinade unused; factor that in for calories or carbs.

Directions with Pictures
The marinating and cooking process is the same whether you bake, air-fry, or grill. Below are the steps for baking in the oven.
- Whisk the marinade ingredients together in a medium bowl until smooth.
- Pat the turkey tenderloins dry and place them in a glass baking dish or a large resealable bag. Pour the marinade over the meat, flip to coat all sides, then cover or seal and refrigerate.
- Marinate at least 30 minutes or up to overnight, turning the meat or spooning the marinade over halfway through.
- When ready to cook, preheat the oven (see recipe card for temperature). Bake the tenderloins in the dish used for marinating or on a rimmed baking sheet until the internal temperature reaches 165°F.
- You do not need to remove all marinade from the meat before cooking; it will caramelize and form a glaze as it cooks. Discard any marinade that has contacted raw meat unless you bring it to a full boil to use as a sauce.
- If you want to use the reserved marinade as a sauce, boil it vigorously for several minutes to eliminate bacteria, then drizzle over the finished turkey or vegetables.
- Let the cooked tenderloins rest 5 minutes before slicing so the juices redistribute. Slice and serve.
Top Tip
Use an instant-read meat thermometer inserted into the thickest part of the tenderloin to ensure it reaches 165°F. This prevents overcooking and guarantees food safety.
What to Serve with Turkey Tenderloin
These sides pair well year-round and make complete, balanced meals with marinated turkey tenderloins:
- Roasted vegetables — Brussels sprouts, carrots, or a medley of peppers, zucchini, and red onion. Roast them on the same sheet pan with the turkey and drizzle with the marinade.
- Creamy mashed potatoes or mashed cauliflower for a lighter option.
- Low-sugar cranberry sauce for a sweet-tart contrast.
- Crispy roasted green beans or sauteed baby carrots for color and crunch.
- Farro pilaf or stuffing for a heartier grain side.
- Roasted asparagus finished with lemon, balsamic, or parmesan.
Storage
Storage: Keep cooked turkey tenderloins in an airtight container in the refrigerator for up to 5 days or freeze for up to 2 months.
Reheating: Reheat in the oven at 325°F until the internal temperature reaches 165°F, or in the microwave at 50% power in short intervals. Add a little broth to the dish and cover to retain moisture while reheating.
FAQ
Marinate at least 30 minutes and up to 24 hours in the refrigerator. Avoid marinating much longer, as extended time can start to break down the meat’s texture.
Searing adds a browned crust and extra flavor. If you sear, wipe away excess marinade to prevent burning, then brown a few minutes per side in a hot skillet before finishing in the oven. Searing isn’t required because the marinade will glaze the meat as it bakes.
Remove excess marinade and discard or boil it if you plan to use it as a sauce. Spray the air fryer basket with oil, place the tenderloin in a single layer, and cook at 350°F until the thickest part reaches 165°F, about 20 minutes, flipping once for even cooking.
