Main Ingredients
Pork Tenderloin
Pork tenderloin is a lean, tender cut of meat that works beautifully with garlic butter sauce.
Unlike pork shoulder, pork tenderloin does not need extremely long cooking times.
Its delicate texture is best preserved by cooking just until it reaches the proper internal temperature.
Baby Potatoes
Baby potatoes are ideal for this recipe because they hold their shape during cooking.
Their thin skins eliminate the need for peeling.
They also absorb the flavorful cooking liquid.
Butter
Butter creates a rich, silky sauce that complements the pork and potatoes.
Unsalted butter allows better control over the seasoning.
Garlic
Fresh garlic provides the signature flavor of this dish.
As it cooks, the garlic becomes mellow and aromatic.
Chicken Broth
Chicken broth adds moisture and helps distribute the garlic butter flavor throughout the crockpot.
Ingredients
- 1½–2 pounds pork tenderloin
- 1½ pounds baby potatoes
- 4 tablespoons unsalted butter
- 5 garlic cloves, minced
- ½ cup low-sodium chicken broth
Optional seasonings: Salt, black pepper, dried rosemary, thyme, or parsley, according to taste.
How to Choose the Best Ingredients
Choosing quality ingredients is an important part of preparing a flavorful slow cooker meal.
For pork tenderloin, look for a fresh cut with a pale pink color and a firm texture.
Avoid confusing pork tenderloin with pork loin. Pork loin is generally larger and requires different cooking times.
Choose baby potatoes that are firm, smooth, and free from soft spots.
Yellow baby potatoes are particularly good because they have a naturally buttery texture.
Red baby potatoes also work well and add color to the finished dish.
For butter, unsalted varieties are recommended because the chicken broth may already contain sodium.
Fresh garlic offers the best aromatic flavor.
Choose garlic cloves that feel firm and are free from mold or excessive sprouting.
Low-sodium chicken broth is a convenient choice because it adds savory flavor without overpowering the other ingredients.
Prepare the Pork Tenderloin
Remove the pork tenderloin from its packaging.
Pat it dry using paper towels.
Inspect the surface for silver skin, a thin, silvery membrane that can become tough during cooking.
Use a sharp knife to carefully remove any visible silver skin.
Season the pork lightly with salt and black pepper if desired.
For additional flavor, you can briefly sear the tenderloin in a hot skillet before placing it in the slow cooker.
Searing is optional, but it creates a lightly browned exterior.
If you choose to sear the meat, heat a small amount of oil in a skillet over medium-high heat.
Brown the tenderloin for approximately 1–2 minutes per side.
Transfer it immediately to the slow cooker.
Prepare the Baby Potatoes
Rinse the baby potatoes under cool running water.
Use a vegetable brush if necessary to remove any dirt.
Pat them dry with a clean kitchen towel.
Small potatoes can remain whole.
Larger baby potatoes should be cut in half so they cook more evenly.
Keeping the potatoes relatively uniform in size helps prevent some pieces from becoming overly soft while others remain firm.
Place the prepared potatoes in a bowl until ready to use.
Prepare the Garlic Butter Sauce
Melt the butter gently in a small saucepan or microwave-safe bowl.
Add the minced garlic.
Stir until the garlic is evenly distributed.
Pour in the chicken broth.
Mix well.
If using optional herbs, add a little dried rosemary or thyme.
The mixture should have a buttery golden appearance with visible pieces of garlic.
This simple sauce provides the main flavor for the pork and potatoes.
Step-by-Step Instructions
Step 1: Arrange the Potatoes
Place the prepared baby potatoes in the bottom of the slow cooker.
Spread them into an even layer.
The potatoes will form a base beneath the pork tenderloin.
Step 2: Add the Pork Tenderloin
Place the prepared pork tenderloin over the potatoes.
Position it in the center of the crockpot.
If the tenderloin is too long, gently curve it to fit without cutting it into small pieces.
Step 3: Pour the Garlic Butter Sauce
Slowly pour the garlic butter mixture over the pork tenderloin.
Allow the sauce to run down the sides of the meat and around the potatoes.
Use a spoon to distribute the minced garlic evenly over the pork.
Step 4: Add Optional Seasonings
Sprinkle a little black pepper, rosemary, or thyme over the ingredients if desired.
Avoid adding excessive salt before tasting the finished sauce.
Step 5: Cover the Slow Cooker
Place the lid securely on the crockpot.
Set the slow cooker to LOW.
Step 6: Cook Until Tender
Cook for approximately 2–3 hours on LOW, checking the pork early.
The pork tenderloin is ready when its thickest part reaches 145°F (63°C), followed by at least 3 minutes of resting.
The potatoes must also be fork-tender. Because potatoes can take longer than pork, particularly when left whole, they may need additional cooking time.
For the most reliable result, partially cook the potatoes first or remove the pork when it is done and continue cooking the potatoes separately in the crockpot.
Step 7: Remove the Pork
Carefully lift the cooked pork tenderloin from the slow cooker using a large spatula or kitchen tongs.
Transfer it to a clean cutting board.
Allow the meat to rest for at least 3 minutes before slicing.
Step 8: Check the Potatoes
Insert a fork into the largest potato.
If the fork slides through easily, the potatoes are ready.
If they are still firm, continue cooking until tender.
Step 9: Finish the Sauce
Stir the garlic butter cooking liquid gently.
For a thicker sauce, transfer it to a saucepan and simmer briefly.
You can also add a small cornstarch slurry if desired.
Step 10: Serve
Slice the pork tenderloin into thick medallions.
Arrange the slices on a serving plate alongside the baby potatoes.
Spoon the warm garlic butter sauce over the pork and potatoes.
Serve immediately.
Tips for the Best Results
Avoid Overcooking the Pork
Pork tenderloin is naturally lean and can become dry if cooked too long.
Check the Temperature
Use a meat thermometer to determine when the pork is ready.
Choose Similar-Sized Potatoes
Uniform potatoes cook more evenly.
Use Fresh Garlic
Freshly minced garlic creates a delicious aromatic sauce.
Do Not Add Too Much Liquid
The pork releases natural juices during cooking.
Rest the Meat Before Slicing
Allowing the pork to rest helps retain its juices.
Slice Against the Grain
Cutting across the muscle fibers creates more tender slices.
Spoon Sauce Over the Pork
Adding sauce just before serving creates a glossy, flavorful finish.
Flavor Variations
Garlic Parmesan Pork Tenderloin
Add grated Parmesan cheese to the finished sauce for a richer flavor.
Honey Garlic Pork Tenderloin
Stir a tablespoon of honey into the garlic butter mixture for a slightly sweet finish.
Lemon Herb Pork Tenderloin
Add lemon zest and a little lemon juice for a bright, fresh flavor.
Dijon Garlic Pork
Mix Dijon mustard into the sauce for a tangy variation.
Creamy Garlic Pork Tenderloin
Stir a little heavy cream into the finished cooking liquid and simmer until slightly thickened.
Rosemary Garlic Pork
Use fresh rosemary for a more aromatic herb flavor.
Spicy Garlic Butter Pork
Add crushed red pepper flakes to the sauce for a subtle kick.
Mushroom Garlic Pork
Add sliced mushrooms to the crockpot for additional savory flavor.
How to Serve
Slow Cooker Garlic Butter Pork Tenderloin with Baby Potatoes is already a satisfying main dish, but several side dishes complement it beautifully.
Steamed green beans are an excellent option because their fresh flavor balances the richness of the garlic butter sauce.
Roasted broccoli is another delicious choice.
A simple garden salad with a light vinaigrette adds freshness and color.
For a heartier dinner, serve the pork with warm dinner rolls.
The bread can be used to enjoy the remaining garlic butter sauce.
You can also pair this dish with sautéed carrots, asparagus, or roasted Brussels sprouts.
For family-style serving, arrange the sliced pork on a large platter with the potatoes surrounding it.
Spoon the sauce over the top and garnish with chopped parsley if desired.
