For an 8-pound bone-in turkey breast, you’re looking at 2 to 2.5 hours in a 325°F oven. That’s it. No algebra required. If yours is boneless, shave off about 30 minutes—but check the label, because packaging loves to trick us.
Why 325°F? Because slow and steady wins the juice race. Too hot, and you get a desert; too cool, and you’re hosting a bacteria picnic. No thanks.
Your Thermometer is Your Best Friend (Wear It Proudly)
I don’t care if you’re a microwave master—use a meat thermometer. Stick it into the thickest part (avoid the bone). You’re aiming for 165°F in the breast. Period.
Fun fact: That “pop-up” plastic button? It’s a liar. Throw it away. Trust the digital probe, and you’ll be the hero of dinner. Plus, you get to say “thermometer” with authority—instant chef points.
