Ingredients

  • Turkey breast bone-in or boneless with skin: Choose a fresh breast with firm skin for the best texture in slow cooking

  • Garlic cloves minced: add fragrant warmth that penetrates the meat
  • Lemon juice and zest: brighten the herb butter giving a subtle citrusy lift
  • Fresh rosemary and sage finely chopped: for authentic herbal flavor avoid dried if fresh are available for better aroma
  • Ground black pepper freshly cracked: for a balanced spicy note
  • Soy sauce: enhances the umami while helping tenderize
  • Salt: to season according to taste
  • Aromatic vegetables like onion celery carrots and garlic: for the slow cooker base provide flavor depth
  • Fresh thyme sprigs: for subtle earthiness
  • Butter and flour for the gravy: create a rich smooth sauce from the pan drippings

Instructions

Season and Slow Cook The Turkey Breast:
Place the butter garlic lemon juice and zest rosemary sage black pepper and soy sauce in a small bowl. Using a fork press and mix them together much like mashing potatoes. The lemon juice and soy sauce will not fully combine but that is okay.
Carefully lift the skin:
Carefully lift the skin of the turkey breast and rub some of this herb butter underneath the skin evenly. Use the remaining herb butter and rub all over the outside of the turkey breast. Lightly season with salt and black pepper then save the leftover herb butter liquid for later.
Arrange vegetables:
At the bottom of your slow cooker arrange the quartered onion celery chunks carrots peeled and cut into pieces whole garlic clove and thyme sprigs evenly.
Place turkey breast:
Place the turkey breast skin side down directly on top of the vegetables. Pour the remaining leftover herb butter liquid into the cavity of the turkey if bone-in.
Cook slow cooker:
Cover the crockpot and cook on high for 1 hour to kick start the cooking then reduce to low and cook for 5 to 6 hours or until the thickest part of the turkey reaches 165 degrees Fahrenheit and juices run clear.
Rest the Turkey and Crisp the Skin:
Carefully remove the turkey breast and place on a foil lined sheet pan. Let it rest for 10 minutes so the juices redistribute and the meat becomes tender.
Preheat broiler:
Preheat your broiler to high and adjust the oven rack about 12 inches from the heating element.
Crisp skin:
Place the turkey breast under the broiler skin side up for 4 to 5 minutes watching closely so it turns golden and crisp but does not burn. Remove once golden.
Make the Gravy:
Strain the cooking liquid from the slow cooker into a measuring cup. Ensure you have 2 cups. If short top off with chicken or turkey broth or plain water.
Melt butter:
Melt butter in a small saucepan over medium heat. Whisk in the flour and cook for around 2 minutes stirring constantly so the mixture does not burn and becomes a paste.
Add cooking liquid:
Slowly whisk in half a cup of the cooking liquid to loosen the roux into a smooth paste. Then gradually add the remaining liquid while whisking constantly to prevent lumps.
Simmer gravy:
Let the gravy simmer on low heat for about 5 minutes until thickened. Taste and adjust seasoning with salt and pepper if needed. Keep warm until ready to serve.

Rosemary is my go to herb here it adds this woodsy fragrance that reminds me of family holidays gathered around the table. The mix of lemon and soy sauce was an unexpected twist that turned this ordinary turkey into something special we all loved.

Storage tips

Store leftover turkey covered in the refrigerator for up to four days. To keep the meat juicy reheat wrapped loosely in foil in the oven or gently in a skillet over low heat with a splash of broth. Gravy can be stored separately in an airtight container in the fridge for up to three days. Reheat gently whisking in a splash of water or broth to thin if needed.

Ingredient swaps

Butter can be substituted with olive oil for a lighter version but note the flavor and texture change slightly. Rosemary and sage can be swapped for thyme and parsley if you prefer different herb notes. Chicken broth or vegetable broth works well if turkey broth is unavailable when topping cooking liquid for gravy.

Serving ideas

Serve slices of this turkey breast with classic mashed potatoes green beans and a cranberry sauce to keep it traditional. For a lighter meal offer alongside a fresh autumn salad with toasted walnuts and apple slices. Leftover turkey also makes amazing sandwiches with cranberry mayo and arugula on crusty bread.

Guide to Cooking

Step 01

Combine butter, minced garlic, lemon juice and zest, rosemary, sage, ground black pepper, and soy sauce in a small bowl. Mash together with a fork until partially blended; some separation is normal.

Step 02

Gently separate the skin from the turkey breast and spread some herb butter underneath. Rub remaining herb butter evenly over the surface of the breast. Lightly season with salt and ground black pepper. Reserve any remaining liquid from the herb butter.

Step 03

Arrange onion, celery, carrots, garlic clove, and thyme sprigs at the bottom of the slow cooker. Place the turkey breast skin-side down on top of the vegetables. Pour reserved herb butter liquid into the turkey cavity. Cover and cook on high for 1 hour, then reduce to low for 5 to 6 hours, until internal temperature reaches 74°C.

Step 04

Remove the turkey breast from the slow cooker and transfer to a foil-lined sheet tray. Let it rest for 10 minutes to redistribute juices.

Step 05

Preheat the broiler to high and position the oven rack approximately 30 cm from the heat source. Broil the turkey breast for 4 to 5 minutes until the skin is golden and crispy. Monitor closely to prevent burning. Remove from the oven before carving.

Step 06

Strain cooking liquid from the slow cooker into a measuring cup; bring total volume to 480 ml using broth or water if necessary. In a saucepan over medium heat, melt butter and whisk in flour. Cook for about 2 minutes. Gradually whisk in half a cup of cooking liquid to form a paste, then slowly add remaining liquid while whisking constantly. Simmer on low heat for 5 minutes until thickened. Adjust seasoning and serve warm.

Extra Suggestions

  1. Ensure the turkey reaches an internal temperature of 74°C for safe consumption. Resting the meat allows juices to redistribute for optimal tenderness.
