After about 1.5 hours, check on it. If the skin is getting too dark—like a deep, worried tan—tent it loosely with aluminum foil. If it’s golden and gorgeous, leave it alone. You’re the boss of this bird.
Continue roasting, and start checking the internal temperature at the 2-hour mark. Insert your thermometer into the thickest part of the breast, avoiding the bone. 165°F is the finish line. Pull it out the second it hits that number.
How Long To Cook A Turkey Breast Roast At 350 at Verda Garcia blog
Here’s the secret: Once you pull it, don’t cut into it immediately. Let it rest on a cutting board, tented with foil, for at least 15-20 minutes. This lets the juices redistribute. If you cut too early, you’ll have a dry, weepy turkey—and a sad kitchen.
What If It’s Taking Too Long?
Relax. Every oven is a drama queen. If it’s 20 minutes past my estimate and still at 160°F, just wait. Don’t crank the heat up—you’ll burn the skin and feel like a turkey yourself. Patience, young padawan.
If you’re in a rush, you can increase the oven temp to 350°F for the last 30 minutes. But 325°F is the sweet spot for tenderness.
And if you totally forget and it’s been 4 hours? Well, you’ll have a well-done bird, but you’ll also have a story. (And maybe some good gravy.)
