How do you cook a turkey breast?

In a casserole dish, combine the turkey breast, mushroom, and Brussels sprouts with the prepared olive oil mixture. Cover the dish with foil and bake in the oven for 45 minutes at 350 degrees Fahrenheit. The internal temperature of the turkey breast is more important than total time cooked, and you’re looking for 165 degrees Fahrenheit in the thickest part of the turkey. If you kept your turkey breast whole instead of chopping it into bite-sized pieces, you will require a longer cook time since it’s so much thicker. Use a meat thermometer just to be safe!

  • I’m curious did you use the really small brussel sprouts? This dish tasted great, I added some cumin just because I like it. However, the brussel sprouts were not fully cooked after 45 minutes but the turkey and mushrooms were. I will either roast the brussel sprouts for about 15 minutes before adding the other ingredients or get the extra small brussel sprouts next time. The dish was delicious though, thank you.
