Rubbed inside and out with whipped rosemary-thyme garlic butter and slow-braised over sweet onions, carrots, and celery, this foolproof butterball turkey breast crockpot recipe delivers ultra-juicy, fork-tender slices and velvety homemade pan gravy while freeing up your oven completely.

Roasting a lean boneless turkey breast in a dry oven is notoriously tricky—even ten minutes too long leaves the center chalky and dry. In our test kitchen, we found that cooking a 3-pound (1.36kg) boneless turkey breast roast on LOW in a sealed slow cooker traps 100% of the natural steam and melted herb butter around the meat.

By elevating the turkey breast on a bed of thick-cut yellow onions, carrots, and celery with just 1/2 cup (120ml) of rich chicken bone broth, the roast gently braises without boiling. Once the internal temperature reaches 165°F (74°C), a quick 4-minute broil crisps the paprika-butter skin to mahogany perfection while you whisk the aromatic crockpot drippings into silky gravy.

Key Ingredients & Why Each One Matters

Boneless Turkey Breast Roast (3 to 3.5 lbs / 1.36–1.6kg): Thawed completely; keep the elastic netting on during cooking so the roast holds its shape and slices cleanly.
Unsalted Butter (6 Tablespoons / 85g, softened): Whipped with garlic and herbs to baste the lean white meat as it melts.
Fresh Rosemary, Thyme & Sage: Finely minced herbs infuse the butter crust with classic holiday flavor.
Minced Garlic & Smoked Paprika: Four garlic cloves add savory depth while smoked paprika gives the skin a rich amber hue.
Yellow Onion, Carrots & Celery: Forms a natural roasting trivet in the slow cooker and flavors the drippings.
Rich Chicken or Turkey Bone Broth (1/2 cup / 120ml): Provides just enough moisture to start the braise without boiling the meat.
Cornstarch (2 Tablespoons / 16g): Whisked with cold broth to thicken the strained drippings into glossy gravy.

Start by Whipping the Garlic Herb Butter & Building the Vegetable Bed

Scatter the onion wedges, carrot chunks, and celery pieces across the bottom of a 6-quart slow cooker and pour in 1/2 cup (120ml) bone broth. Mash the softened butter with minced garlic, rosemary, thyme, sage, smoked paprika, salt, and black pepper into a paste.

Pat the thawed turkey breast dry, loosen the skin gently, and rub half the herb butter under the skin and the rest over top. Place skin-side up over the vegetables in the slow cooker.

The Secret to Moist Slow Cooker Turkey & Crispy Skin

Cooking on LOW and pulling the roast at 163°F–165°F (73°C–74°C) on an instant-read thermometer locks in moisture before a 4-minute broil crisps the buttered skin.

Three Rules for Perfect Crockpot Turkey Breast

Keep the butcher’s netting on until after broiling: The netting holds the boneless lobes together for even cooking and neat slices.
Always cook on LOW rather than HIGH: Five hours on LOW melts the butter into the breast meat without tightening the lean fibers.
Broil for 3 to 4 minutes before resting: Brushing with pan juices and broiling on a sheet pan gives you crisp, golden skin.

How to Make Butterball Turkey Breast in the Crockpot (Step-by-Step Guide)

Cover and cook on LOW for 5 to 5.5 hours without lifting the lid until the center registers 163°F–165°F (73°C–74°C).

Basting the golden slow-cooked turkey breast with herb butter drippings on a baking sheet before broiling — Step 3: Transfer the tender turkey breast to a baking sheet and broil 3 to 4 minutes until deeply golden.

Whisking strained slow cooker turkey drippings with a cornstarch slurry in a saucepan until glossy brown gravy forms — Step 3: Transfer the tender turkey breast to a baking sheet and broil 3 to 4 minutes until deeply golden.

Transfer the turkey to a baking sheet, brush with 2 Tablespoons pan juices, and broil for 3 to 4 minutes until crisp and golden. Tent with foil and rest 15 minutes before removing the netting.

Strain the slow cooker liquid into a saucepan (about 2 cups), bring to a simmer, and whisk in 2 Tablespoons cornstarch mixed with 2 Tablespoons cold broth. Simmer 2 minutes until glossy, then carve the turkey and spoon the warm gravy over top.

Common Mistakes to Avoid

Removing the netting before cooking: Cutting off the netting raw causes the boneless roast to fall open and cook unevenly.
Adding too much liquid: Half a cup of broth is plenty because the turkey and vegetables release over 1.5 cups of juices.
Overcooking past 165°F (74°C): Check internal temperature at the 4.5-hour mark so the lean white meat stays juicy.
Skipping the 15-minute rest: Resting lets the juices redistribute so every carved slice stays moist.

Substitutions & Flavor Variations

Bone-In Turkey Breast: Cook a 5 to 6-pound bone-in breast on LOW for 6 to 6.5 hours.
Citrus-Herb Orange Butter: Stir 1 Tablespoon orange zest and 1 teaspoon honey into the butter.
Cajun Spiced Turkey: Swap herbs for 1.5 teaspoons Cajun seasoning and 1 teaspoon smoked paprika.
Flour Roux Gravy: Whisk 3 Tablespoons flour into 2 Tablespoons butter before adding drippings.

Make-Ahead, Storage & Reheating Guide

Prep Ahead: Mix the herb butter and chop the vegetables up to 24 hours ahead in the fridge.

Storage: Store slices covered in gravy in an airtight container for up to 4 days.

Reheating: Warm slices covered at 325°F (165°C) with a splash of broth for 10 minutes.
