Why it works
Turkey breast is lean and prone to drying out, making low-and-slow smoking with injection essential for moisture retention. The garlic and herb injection seasons the meat throughout while butter-based liquid keeps it tender. The final high-heat phase renders fat in the skin and develops color and crispness without overcooking the interior.
This cook is built for intermediate pitmasters running a smoker setup, but the real win is that the method stays adaptable if your fire drifts or your timing gets crowded.
- Combine melted butter, chicken broth, apple juice, minced garlic, thyme, rosemary, 1 tablespoon salt, and 1 teaspoon black pepper in a bowl. Whisk until well combined. Fill an injector syringe with the mixture.
- Pat the turkey breast dry with paper towels. Make 8-10 injection points across the thickest portions of the meat. Inject 1-2 ounces of mixture at each point, distributing evenly. Season the exterior with 1 tablespoon salt and remaining black pepper. Let rest uncovered in the refrigerator for 2-4 hours.
- Set the smoker to 275°F. Soak hickory or oak wood chunks in water for 30 minutes, then add to the smoker box or grates over the heat source. Allow the smoker to stabilize at temperature with thin blue smoke flowing.
- Remove turkey breast from refrigerator 30 minutes before smoking. Place skin-side up on the smoker grates, positioned over the drip pan. Maintain 275°F throughout this phase.
- Smoke for 90-120 minutes, until the internal temperature at the thickest part of the breast reaches 155°F. Maintain steady smoke and avoid opening the smoker unnecessarily.
- Increase smoker temperature to 425°F. Continue cooking for 15-20 minutes until the internal temperature reaches 165°F and the skin is golden brown and crispy.
- Remove turkey breast from smoker and place on a cutting board. Tent loosely with foil and rest for 10 minutes to allow juices to redistribute. Slice against the grain and serve immediately.
