Ingredients for Keto Pork Tenderloin Crock Pot
Herb-infused pork tenderloin slow-cooked to perfection with keto-friendly ingredients for a hands-off meal.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🥩 | 2 lb | Trimmed of excess fat |
| Olive Oil 🫒 | 1 tbsp | Extra-virgin preferred |
| Dried Rosemary 🌿 | 1 tbsp | Crushed between fingers |
| Dried Thyme 🍃 | 1 tbsp | Rubbed to release oils |
| Garlic Powder 🧄 | 1 ½ tsp | Not garlic salt |
| Onion Powder 🧅 | 1 ½ tsp | Freshly ground if possible |
| Kosher Salt 🧂 | 1 tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Smoked Paprika 🌶️ | 1 tsp | Adds depth and color |
| Chicken Broth 🥣 | ½ cup | Low-sodium preferred |
| Apple Cider Vinegar 🍏 | 1 tbsp | Balances the richness |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
| Butter 🧈 | 2 tbsp | Unsalted, cut into cubes |
The pork tenderloin is the foundation—opt for 2 pounds with even thickness for consistent cooking. Whole Foods or Costco offer quality options. Dried herbs like rosemary and thyme should be freshly crushed to maximize their aromatic potential. Avoid pre-ground spices; they lose potency quickly. For the best results, use Diamond Crystal kosher salt as it dissolves evenly without overpowering the dish.
No pork tenderloin? Pork shoulder works but requires longer cooking. Substitute fresh herbs at triple the amount for dried, though the flavor profile will differ slightly. If avoiding vinegar, lemon juice offers a similar acidity. For a deeper smoke flavor, chipotle powder can replace smoked paprika. Low-sodium broth is key—regular can oversalt the dish.
Store pork in its original packaging up to 2 days before cooking or freeze for 6 months. Herbs keep in a cool, dark place for 1 year. Once cooked, leftovers stay fresh in the fridge for 4 days or freeze for 3 months.

Step-by-Step Instructions for Pork Tenderloin Crock Pot
This hands-off method delivers perfectly tender results with minimal active cooking time.
Step 1: Sear the Pork Tenderloin for Depth of Flavor
Pat the 2 lb Pork Tenderloin dry with paper towels to ensure a good sear. Heat the 1 tbsp Olive Oil in a large skillet over medium-high heat until it shimmers but doesn’t smoke.
Sear the tenderloin on all sides for 2-3 minutes per side until golden brown. This step builds a flavorful crust that will infuse the entire dish as it slow-cooks. Transfer the seared pork to your crock pot.
Step 2: Create the Herb-Infused Cooking Liquid
In a small bowl, combine the 1 tbsp Dried Rosemary, 1 tbsp Dried Thyme, 1.5 tsp Garlic Powder, 1.5 tsp Onion Powder, 1 tsp Kosher Salt, 0.5 tsp Black Pepper, and 1 tsp Smoked Paprika. Rub this mixture evenly over the seared pork.
Pour the 0.5 cup Chicken Broth and 1 tbsp Apple Cider Vinegar into the crock pot around the pork, not over it, to avoid washing off the herbs. Add the 2 tbsp Butter in small cubes on top of the pork.
Step 3: Slow Cook to Keto Perfection
Cover the crock pot and cook on low heat for 6-7 hours or on high heat for 3-4 hours. The pork is done when it reaches an internal temperature of 145°F and pulls apart easily with a fork.
The slow cooking process ensures the pork remains tender while absorbing the rich, herb-infused liquid. Resist the urge to lift the lid—retaining steam is crucial for even cooking.
Step 4: Rest and Garnish for Serving
Once cooked, transfer the pork to a cutting board and let it rest for 10 minutes. This allows the juices to redistribute, ensuring every slice stays moist and flavorful.
Slice the pork against the grain into ½-inch thick medallions. Spoon some of the cooking liquid over the top and garnish with the 0.25 cup Fresh Parsley for a bright finish. Serve immediately with your favorite keto sides.
Pro Tips For Making Keto Pork Tenderloin Crock Pot
- Sear First: I learned this the hard way—skipping the sear leaves the pork bland. Heat 1 tablespoon olive oil in a pan, sear the tenderloin on all sides until golden (about 2-3 minutes per side) before transferring to the crock pot.
- Rub Generously: Sounds weird, but it works: mix the rosemary, thyme, and garlic powder with 1 tablespoon olive oil, then rub it all over the pork. The oil helps the spices stick and penetrates deeper.
- Don’t Overcook: After burning one too many tenderloins, I finally figured out pork is done at 145°F. Use a meat thermometer and pull it out as soon as it hits that temp—it’ll keep cooking a bit off the heat.
- Add Liquid Last: My grandmother swore by this, and she was right: add any extra liquid (like broth) only after searing and seasoning. This keeps the spices from washing off and the meat from steaming instead of browning.
Pro Cooking Tips for This Dish
Searing for Flavor
Always pat the pork dry with paper towels before searing—this ensures a deep, golden crust. Heat 1 tbsp olive oil in a heavy skillet over medium-high heat until shimmering. Sear the tenderloin for 2-3 minutes per side until browned. 🌡️
Herb Application
Crush the dried rosemary and thyme between your fingers to release their oils before mixing with other spices. Rub the blend evenly over the seared pork, pressing gently so it adheres well. This step maximizes flavor infusion during slow cooking.
Liquid Balance
Pour ½ cup chicken broth and 1 tbsp apple cider vinegar around—not over—the pork to avoid washing off the herbs. Add 2 tbsp butter cubes on top. The liquid should come about ½ inch up the sides of the crock pot.
Low and Slow
Cook on low for 6-7 hours or high for 3-4 hours without lifting the lid. The pork is done at 145°F internal temperature. I find low heat yields the most tender results, as it allows the connective tissue to break down gradually.
Resting Matters
Let the pork rest for 10 minutes after cooking. This lets juices redistribute, so every slice stays moist. Tent loosely with foil to keep it warm. Slice against the grain into ½-inch medallions for the best texture. 💡
Butter Timing
Add butter at the start for richness, or stir it into the cooking liquid at the end for a glossy finish. I prefer the latter method, as it creates a silky sauce to spoon over the pork when serving.

Frequently Asked Questions
Can I skip searing the pork?
You can, but searing adds depth of flavor. Skipping it saves time but may result in less complex taste. The 2-3 minutes per side creates a crust that enhances the final dish.
What keto sides pair well?
Try roasted Brussels sprouts, cauliflower mash, or a crisp green salad. These complement the herb-infused pork without adding carbs. Keep sides simple to let the pork shine.
How do I prevent dry pork?
Don’t overcook—remove at 145°F and let it rest for 10 minutes. Also, ensure enough liquid in the crock pot and avoid lifting the lid during cooking.
Can I use fresh herbs instead?
Yes! Use triple the amount of fresh herbs for dried. For example, 3 tbsp fresh rosemary instead of 1 tbsp dried. Fresh herbs add a brighter, more vibrant flavor.
