Ingredients You’ll Need
Pork Tenderloin
- 1–1.5 pounds pork tenderloin, trimmed of silver skin and excess fat
Slow Cooker Seasonings
- 2 tablespoons olive oil
- 3 cloves garlic, minced
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon dried thyme or rosemary
- Optional: 1/2 teaspoon smoked paprika for depth of flavor
Optional Sauce or Glaze
- 1/4 cup low-sodium chicken broth or apple cider
- 2 tablespoons honey or maple syrup
- 1 tablespoon Dijon mustard
- 1 teaspoon balsamic vinegar
Optional Vegetables

- 1 medium onion, sliced
- 2–3 potatoes, diced
- 1 cup green beans or broccoli florets (added near end of cooking)
Optional Garnish

Pro Tips
Trim silver skin and excess fat before cooking. Silver skin does not break down during slow cooking and can make the tenderloin tough.
Pat the pork dry before seasoning to help the rub adhere and enhance flavor.
Use a meat thermometer to check internal temperature if desired. While slow cookers vary, pork is perfectly cooked at 145°F (63°C) internally and can be left to cook longer for shredding.
If adding vegetables, place root vegetables like carrots and potatoes at the bottom of the slow cooker for even cooking. Add quick-cooking vegetables like green beans or broccoli near the last 30 minutes to prevent overcooking.
Optional sauces or glazes can be added at the start for deep flavor or during the last 30 minutes of cooking to create a sticky, caramelized finish.
Slow cooker pork tenderloin is ideal for meal prep. Cook the pork and vegetables together, then portion into containers for easy lunches or dinners throughout the week.
Tools You’ll Need
- Slow cooker (4–6 quart size recommended)
- Knife and cutting board
- Small bowl for mixing seasonings or glaze
- Tongs or spatula for handling the pork
- Measuring cups and spoons
Substitutions and Variations
Use fresh herbs instead of dried for a brighter flavor; double the amount of fresh herbs to match intensity.
Swap honey or maple syrup with brown sugar or agave for a different sweetness profile.
Try different liquids: apple juice, chicken broth, or even white wine can add flavor to the slow cooker.
Add root vegetables like sweet potatoes, parsnips, or turnips for extra flavor and nutrition.
For a tangy variation, incorporate mustard, balsamic vinegar, or lemon juice into the slow cooker during the last hour of cooking.
Slow cooker pork tenderloin is a hands-off, protein-packed dish that’s easy to prepare, versatile, and consistently tender and flavorful. Its juicy texture, aromatic seasoning, and adaptability make it a recipe you’ll return to again and again.
Make Ahead Tips
Slow cooker pork tenderloin is perfect for preparing ahead of time, making it an ideal recipe for busy weeknights, meal prep, or family gatherings. You can season or marinate the pork tenderloin up to 24 hours in advance and store it in the refrigerator.
Use a resealable bag or airtight container with olive oil, garlic, and herbs. This allows the flavors to penetrate the meat, creating a more flavorful and tender final dish.
Vegetables that accompany the pork can also be prepped in advance. Slice carrots, onions, and potatoes, and store them in separate containers in the refrigerator. This ensures that the vegetables cook evenly in the slow cooker and allows for quick assembly when you’re ready to cook.
If you plan to use a glaze or sauce, prepare it ahead of time and store it in a small airtight container. Brush it over the tenderloin during the last 30–60 minutes of cooking for a slightly caramelized finish, or mix it with the slow cooker juices for a flavorful sauce.
For meal prep purposes, cooked pork tenderloin can be stored in the refrigerator for up to three days. Slice the pork immediately after cooking and portion it with cooked vegetables for easy lunches or dinners throughout the week. This makes slow cooker pork tenderloin a convenient, protein-rich meal option for busy days.
For long-term storage, the cooked tenderloin can be frozen. Wrap tightly in plastic wrap, then place in a freezer-safe bag or container. Freeze for up to three months. Thaw overnight in the refrigerator before reheating gently in a skillet, oven, or microwave. Avoid high heat to maintain the tender, juicy texture.
Instructions
Step 1: Prepare the Slow Cooker
Lightly grease the slow cooker with olive oil or nonstick spray. This prevents the pork and vegetables from sticking and helps with cleanup.
Step 2: Season the Pork
Pat the pork tenderloin dry with paper towels to remove any moisture. Trim off silver skin and excess fat to ensure even cooking.
In a small bowl, combine olive oil, minced garlic, salt, black pepper, and dried herbs like rosemary or thyme. Rub the mixture evenly over the pork, coating all sides.
Step 3: Sear the Pork (Optional)
For enhanced flavor and color, sear the pork tenderloin in a hot skillet over medium-high heat for 2–3 minutes per side. This step is optional but creates a golden-brown crust that adds aroma and depth.
Step 4: Add Vegetables
Place chopped root vegetables like carrots, onions, and potatoes at the bottom of the slow cooker. They form a flavorful base for the pork and cook evenly while absorbing the juices.
Step 5: Place Pork in Slow Cooker
Lay the seasoned pork tenderloin on top of the vegetables. Add optional liquids, such as chicken broth, apple cider, or a small amount of water, to keep the pork moist and create a flavorful sauce.
Step 6: Cook on Low or High
Cover and cook on low for 6–8 hours or on high for 3–4 hours, depending on your schedule. The pork is done when it reaches an internal temperature of 145°F (63°C). Root vegetables should be tender, and the pork should be juicy and easy to slice or shred.
Step 7: Add Quick-Cooking Vegetables (Optional)
If adding quick-cooking vegetables like green beans or broccoli, add them during the last 30–45 minutes of cooking. This prevents overcooking and maintains their bright color and texture.
Step 8: Optional Glaze
Brush a glaze, such as a honey-Dijon mixture or balsamic reduction, over the pork during the last 30–60 minutes of cooking. This adds a lightly caramelized finish and enhances flavor.
Step 9: Rest and Slice
Remove the pork tenderloin from the slow cooker and place it on a cutting board. Tent loosely with foil and allow it to rest for 5–10 minutes. Slice into 1/2–inch medallions and serve with the cooked vegetables and sauce from the slow cooker.
Serving Suggestions
Serve slow cooker pork tenderloin with the cooked root vegetables for a one-pot meal. Pair with steamed greens, rice, quinoa, or mashed potatoes to create a complete dinner.
For a lighter option, serve the pork over a bed of fresh salad greens, adding roasted or steamed vegetables and a drizzle of the slow cooker juices as dressing.
Leftover tenderloin slices can be used in sandwiches, wraps, grain bowls, or salads. Combine with roasted vegetables or whole grains for quick, nutritious lunches throughout the week.
Add fresh herbs like parsley, thyme, or rosemary for garnish and visual appeal. A squeeze of lemon or lime over the top brightens the flavors and balances the richness of the pork.
Slow cooker pork tenderloin is versatile enough for casual weeknight dinners or special occasions. Its tender, juicy texture and flavorful seasoning make it a recipe you’ll return to again and again, whether served fresh, in meal prep containers, or as part of a creative leftover dish.

Leftovers and Storage
Slow cooker pork tenderloin is delicious fresh, but it also stores very well, making it ideal for meal prep or quick weekday dinners. Once cooked, allow the pork tenderloin to cool slightly before transferring it to an airtight container.
Properly stored, cooked pork tenderloin will remain fresh in the refrigerator for three to four days, maintaining its tender, juicy texture.
If you have leftover slices, reheat gently to preserve flavor and moisture. Place the pork in a baking dish, cover lightly with foil, and warm in a 325°F (163°C) oven for 10–15 minutes. Alternatively, reheat in a nonstick skillet over low heat or use short microwave intervals, checking frequently to avoid drying out the meat.
For longer-term storage, pork tenderloin can be frozen. Wrap the meat tightly in plastic wrap or aluminum foil and place it in a freezer-safe bag or container. Frozen tenderloin will maintain quality for up to three months.
Thaw overnight in the refrigerator and reheat gently in the oven or skillet to retain tenderness. This is especially useful for meal prepping multiple portions or for having protein on hand for quick meals.
Leftover pork tenderloin can also be repurposed creatively. Slice or dice it for sandwiches, wraps, or sliders. Add it to salads, grain bowls, pasta dishes, or stir-fries to create protein-rich meals with minimal effort. You can even shred the pork and mix it with a light sauce or glaze for tacos or burritos, making it extremely versatile for quick weeknight meals.
Optional sauces or glazes can be added when reheating to enhance flavor and moisture. A light drizzle of balsamic reduction, honey-mustard glaze, or reserved slow cooker juices will help restore freshness and ensure the pork remains juicy.
