The broth is still bubbling gently when the slow-cooker lid comes off, and the garlic butter has mingled with it into a savory cooking juice. That’s the part I don’t want to waste. With this slow cooker garlic butter turkey tenderloin, the meat cooks right in that flavorful liquid, then gets sliced and finished with a spoonful over the top.
I like this method because it keeps the work simple without leaving the turkey plain. The tenderloin gets seasoned before the melted butter and minced garlic go on, so the garlic flavor stays close to the meat as it cooks. Use an instant-read thermometer rather than judging doneness by color; turkey tenderloin is lean, and the thickest part is what matters. The slices come out tender with a buttery, garlicky finish and plenty of juices for serving.
Kitchen Note
Tenderloins don’t all have the same shape, so I start checking at the low end of the cooking window. Take the temperature in the thickest part; a clock can’t account for a thicker end or a slow cooker that runs hot.
Save this slow cooker garlic butter turkey tenderloin for a hands-off main with tender slices and garlicky pan juices.
Why This Turkey Tenderloin Needs Juices, Not a Slow-Cooker Sear
A slow cooker gives turkey tenderloin a moist, gentle environment, but it won’t create the browned surface you’d get from a skillet or oven. This version doesn’t depend on a crust. The chicken broth goes around the turkey, while the paprika, salt, and pepper season the meat itself; melted butter and garlic then bring richness to the cooking liquid as well as the surface.
That distinction matters when you serve it. Searing would add a browned flavor, but it would also add a pan and another step. Here, the finish is the spoonful of cooking juices over the sliced turkey. Keep the liquid in the cooker, and don’t expect the paprika to turn into a crisp coating. It gives the tenderloin color and mild warmth, while the butter and garlic make the slices taste seasoned from edge to edge.
What the Garlic Butter and Broth Each Bring to the Pot
- Turkey tenderloin — This lean, mild cut is the center of the dish, so choose thawed tenderloins that fit comfortably in the 6-quart cooker. Chicken tenderloins are a possible swap, but their shape and thickness differ; use the thermometer rather than assuming the turkey timing will fit them exactly.
- Low-sodium chicken broth — The broth keeps the bottom of the cooker moist and becomes part of the serving juices. A carton from the grocery store is fine; unsalted chicken broth works in the same amount if that’s what you have, with the listed salt still giving the dish its seasoning.
- Unsalted butter — Butter gives the garlic a rich base and rounds out the broth. A dairy-free block-style butter can replace it one-for-one if needed, though the juices won’t have quite the same buttery taste. Melt it before stirring in the garlic so the garlic can be distributed evenly.
- Garlic and paprika — Fresh garlic cloves bring a sharper aroma than prepared minced garlic, while paprika adds gentle warmth and color. If using prepared minced garlic, use the package’s equivalent for four cloves; for a smokier finish, smoked paprika can replace regular paprika in the same amount.
Layering the Turkey So the Butter and Garlic Reach Every Slice
Set the Tenderloin in Its Cooking Liquid
Place the thawed turkey tenderloin in a 6-quart slow cooker and pour the chicken broth around it. Season the turkey with kosher salt, black pepper, and paprika so the spices land on the meat rather than disappearing into the broth. The broth belongs around the tenderloin, not poured over the seasoned top. Keep the tenderloin arranged in the cooker rather than folding or wedging it tightly.
Pour on the Melted Garlic Butter
Melt the butter, stir in the minced garlic, and pour the mixture evenly over the turkey. Stir the garlic through the melted butter first; otherwise, the garlic can collect in one spot instead of spreading across the top. Let the butter coat as much of the tenderloin as it naturally will. There’s no need to brown the meat before it goes into the slow cooker.
Cook to Temperature, Then Slice
Cover and cook on LOW for 3–4 hours or HIGH for 2–3 hours, until the thickest part registers 165°F on an instant-read thermometer. Begin checking at the lower end of whichever time range you’re using. If the reading is below 165°F, cover the cooker again and continue cooking before checking once more. Transfer the cooked tenderloin to a cutting board, rest it for 5 minutes, slice, and spoon the cooking juices over the slices.
Two Easy Ways to Adapt the Garlic Butter Turkey
Make It Dairy-Free with Plant-Based Butter
Use the same amount of dairy-free block-style butter in place of the unsalted butter, then melt it and stir in the garlic just as you would for the original. The turkey will still cook in the broth and seasonings, though the finished juices will taste less rich and distinctly buttery.
Serve It Pulled Instead of Sliced
For a softer, shredded texture, pull the cooked tenderloin apart with two forks instead of cutting it into slices. Mix the strands with some of the garlic-butter cooking juices so they stay moist. This changes the serving texture, not the doneness target or the cooking method.
Storage and Reheating
- Refrigerator: Store leftovers in an airtight container for 3–4 days. The turkey will firm up as it chills, so keep some cooking juices with it.
- Freezer: Freeze the sliced or pulled turkey with some of its juices in a freezer-safe container for up to 3 months. Thaw it in the refrigerator before reheating; the texture may be a little softer after freezing.
- Reheating: Warm covered in a microwave-safe dish or covered saucepan with a spoonful of cooking juices, until the turkey reaches 165°F. Avoid heating it uncovered for a long stretch, which can dry out this lean cut.
