This buttermilk brined turkey breast is perfect for Thanksgiving or any family dinner! Although the breast is arguably the best part, it has a bland flavor, so making a zesty buttermilk turkey brine adds a much needed flavor boost. Get our tips for a tender, juicy poultry dinner that everyone raves about!

Let’s face it, big turkeys take up a lot of space in the fridge. For smaller gatherings, save yourself some time, money, fridge space – and hassle – by making a smaller breast with a buttermilk turkey brine instead.
Why Make a Buttermilk Brined Turkey Breast?
So, what does brining poultry do? Well, we wondered that, too! Here’s what we found out.
Soaking poultry in a saltwater brine makes it more tender, juicy, and tasty. The acidity and calcium in buttermilk help break down the proteins, making it more tender.
And, the brine process creates a reverse osmosis process that infuses the meat with salt for much needed flavor.

Over time, reverse osmosis creates a natural shifting of moisture that helps keep it moister.
Ingredients and Substitutions
- Seasonings – the seasonings in brines help infuse added flavor, beyond salt. And, It’s okay to use whole herbs, like bay leaves, since it’s drained like marinade and discarded. We recommend basil, coriander seed, peppercorns, mustard seeds, and garlic, but you can substitute them with your preferred herbs and spices.
- Buttermilk – I don’t recommend using a substitution for buttermilk. Adding vinegar or lemon to milk will not have the same effect in this buttermilk turkey brine. You can use 2% milk fat or non-fat.
- Salt – You can use any type of salt, but I prefer Kosher salt for a few reasons. First, the sodium level is consistent. Another reason is it comes in a box, so I always have enough on hand in the pantry. If you use sea salt or table salt, use 1 cup as a substitution. Kosher salt is less dense.

A breast is about 6-7 pounds, the ideal size for this buttermilk brine recipe. See the recipe tips below about how to brine a whole turkey!

Equipment for Brining
- Large saucepan to bring the salt, water, and spices to a boil.
- A heavy-duty, brining bag to hold the meat and brine. Look for a 4-gallon size or one labeled for up to 7 pounds.
- Large, non-reactive tall stock pot or jumbo-sized bowl to hold the brining bag. About 12 quarts in size is ideal.
- Basting brush for melted butter.

Recipe Tips for Making Buttermilk Turkey Brine
- Start early! Brining takes at least a day. Plus, it takes a few hours for the brine mixture to cool. So, if you need 3 days to thaw your poultry – add a day to the process. If you have a frozen turkey, see our recipe tips below.
- Rinse off the brining mixture and let air dry before roasting. To avoid overly salty poultry, remove it from the brine and rinse it thoroughly. Then, pat it dry with paper towels. Be sure to let it air dry for at least 15 minutes. Moisture will prevent getting that crispy, deep golden hallmark of the perfect roasted bird.
- Thawing first isn’t essential. If your breast is frozen, you can thaw while brining. Give it an additional day to defrost and brine in the fridge. So, plan for a total of 36-48 hours.
- Double the recipe for a full-sized turkey. This recipe makes about 1-1/2 gallons of brine, perfect for an average-sized roast. For a medium-sized bird (12-15 pounds), double the recipe.
- Submerge the meat completely. Use a tall stock pot or bowl to help the turkey breast stay covered with brine.
- Let poultry rest before carving. When it comes to poultry, allow it to rest on the serving platter or a carving board before slicing. This lets the juices redistribute. If you cut it right away, the juices will run out leaving the meat drier.
