- ½ tsp freshly ground black pepper – For layering flavor; freshly ground offers the best taste.
- 2 tbsp extra virgin olive oil – Used for browning and adds richness. Feel free to substitute it with melted butter for a different flavor.
- 2 medium onions, peeled and cut into thick rounds – These provide a savory base that caramelizes beautifully during roasting.
- 2 tsp dried oregano – Adds depth; you can aid the flavor with Italian seasoning if you prefer.
- 2 cups chicken stock – This keeps your turkey moist while it cooks. Homemade stock will give you the best flavor!
- 2 tbsp unsalted butter – For the gravy; it adds richness. Use margarine if you want a dairy-free option.
- ¼ cup plain/all-purpose flour – A thickening agent for your gravy. Gluten-free flour can be a good substitute if needed.
- 2 cups stock from the pan juices – This is the key to a delicious gravy. Be sure to save all the flavorful drippings!
How to Make Slow Roasted Turkey Breast
Preheat and Prepare: Start by removing the turkey breast from the refrigerator. You’ll want it to be at room temperature when it hits the oven for even cooking. With a sharp knife, make deep slits into the skin and fat side of the breast, inserting slivers of garlic and sprigs of fresh rosemary. Ideally, these should be spaced out evenly, about 1 inch apart. Don’t forget to rub salt and pepper all over the breast, both for flavor and to draw out moisture.
Truss and Brown: After seasoning, truss the turkey with kitchen twine. This step isn’t just for looks—it helps the turkey cook uniformly. Preheat your oven to 320°F. In a sturdy Dutch oven, heat olive oil over medium-high heat until shimmering. Add your turkey breast skin-side down and sear for 3-5 minutes until it’s beautifully brown. Turn it over and brown the other side too.
Add Onions & Stock: Now that the turkey is brown, turn off the heat and add the onion rounds around the turkey. Lightly sprinkle with oregano and pour chicken stock around the edges. This stock will keep the meat moist during the slow roasting process. Cover the pot with a tight-fitting lid and pop it in the preheated oven.
Baste and Roast: After 45 minutes, give your turkey a loving baste with its own juices. This helps enhance the flavors and keeps the meat succulent. Return it to the oven for an additional 45 minutes, or until the turkey’s internal temperature reaches 165°F. Depending on your oven, the total cooking time can vary widely!
Rest and Prepare Gravy: Carefully transfer your turkey to a warm serving dish and cover loosely with foil. This resting period, about 15 minutes, allows juices to redistribute throughout the meat, keeping it juicy. While it rests, create a flavorful gravy. Melt the butter in a small saucepan over medium heat, add flour to create a roux, and gradually whisk in the pan juices until it thickens, usually just a few minutes.
Serve and Enjoy: Now for the fun part! Slice your turkey breast into thick pieces, about half an inch. You can serve it with the gravy drizzled on top and cranberry sauce on the side for that delightful pop of tartness.
Storing & Reheating
If you have leftovers, let the turkey cool before storing it in an airtight container at room temperature for up to 2 hours. After that, refrigerate it for up to 4 days. For longer storage, you can freeze the sliced turkey for up to 3 months. Just make sure to wrap it tightly to avoid freezer burn. When you’re ready, reheat in the oven at 350°F for about 15–20 minutes, or until warmed through. It’s worth noting that while the turkey may lose a little moisture during reheating, a drizzle of gravy can bring it back to life!
Chef’s Helpful Tips
- Avoid Overcooking: Use a meat thermometer to check doneness; removing it right at 165°F ensures juicy meat.
- Room Temperature: Allow your turkey to sit for 15 minutes before cooking for more even cooking.
- Timely Basting: Remember to baste your turkey halfway through cooking; this makes a significant difference in flavor!
- Gravy Consistency: If the gravy is too thick, simply whisk in a bit more stock to thin it out to your desired consistency.
- Make-Ahead: You can roast the turkey a day in advance and reheat for an easy holiday meal with minimal fuss.
Turkey lovers, this slow roasted turkey breast will surely become a family favorite for years to come! Not only is it bursting with flavor and tender juicy goodness, but it’s also a simple recipe that brings people together. Go ahead—experiment with the herbs and spices to make it your own, and enjoy every delicious bite!
