Important Recipe Tip
The turkey breast is already cooked, so we cook it on low. Don’t be tempted to crank the heat to high. This will dry it out.

FREEZE: Place the sliced turkey in a freezer-safe container and freeze for up to three months.
Recipe FAQs
Can I cook it on high?
You can, but it may dry out. Low heat is best for tender, juicy turkey.
How do I know when it’s done?
Use a meat thermometer. The turkey should reach an internal temperature of 165°F.
Can I use frozen turkey breast?
Sure, but I recommend thawing it first, to ensure even cooking.

I tried this recipe for.Thanksgiving 2025. My guests loved it. Personally, I would use half the salt next time. But nobody but me seemed to mind. The sage adds terrific flavor to the ham.
I made this for a large Friendsgiving we hosted, and more than 5 people asked me for the recipe. My husband said it’s the best turkey he’s ever had. It’s so incredibly easy and comes out so moist!
