Ingredients
You only need four main ingredients.
- 1 1/2 to 2 pounds pork tenderloin
- 1 can (10.5 ounces) cream of mushroom soup
- 1 packet dry onion soup mix
- 1 cup chicken broth
These simple ingredients create a creamy, savory sauce that keeps the pork flavorful while it cooks.
The cream of mushroom soup provides the rich base, while the onion soup mix adds concentrated savory flavor. Chicken broth helps loosen the sauce and provides moisture during cooking.
How to Make 4-Ingredients Slow Cooker Pork Tenderloin
Step 1: Prepare the Slow Cooker
Lightly coat the inside of your slow cooker with nonstick cooking spray if desired.
This can make cleanup easier once dinner is finished.
Step 2: Add the Pork Tenderloin
Place the pork tenderloin in the bottom of the slow cooker.
If your tenderloin is very long, you can cut it into two pieces so it fits comfortably inside the crockpot.
Step 3: Make the Sauce
In a medium bowl, combine the cream of mushroom soup, dry onion soup mix, and chicken broth.
Whisk until the mixture is mostly smooth.
The sauce will be fairly thick, but it will loosen as it cooks.
Step 4: Pour the Sauce Over the Pork
Pour the mixture evenly over the pork tenderloin.
Use a spoon or spatula to spread the sauce over the top.
Step 5: Slow Cook
Cover the slow cooker and cook on:
LOW: About 2 1/2 to 4 hours
HIGH: About 1 1/2 to 2 1/2 hours
Cooking time varies depending on the size and thickness of the tenderloin and the slow cooker itself.
Because pork tenderloin is a lean cut, avoid cooking it for an excessively long period.
Check the thickest part with an instant-read thermometer. Pork is safely cooked at 145°F (63°C), followed by a 3-minute rest.
Step 6: Rest and Slice
Carefully remove the pork tenderloin from the slow cooker and place it on a cutting board.
Allow it to rest for at least 3 minutes before slicing.
Cut the pork into thick slices and spoon the creamy onion gravy over the top.
The Secret to Tender Pork Tenderloin
Pork tenderloin is already naturally tender, so the key is not overcooking it.
Many people assume that every slow cooker pork recipe needs to cook for six to eight hours. That’s not true for pork tenderloin.
Unlike pork shoulder, pork tenderloin is lean and doesn’t need a long cooking time to become tender.
Start checking the temperature toward the earlier end of the cooking range. Once the center reaches 145°F, remove the pork and allow it to rest.
This helps keep the meat juicy and tender.
Should You Brown the Pork First?
You can, but it isn’t necessary.
For the easiest four-ingredient slow cooker version, place the pork directly into the crockpot.
If you want extra browned flavor, you can quickly sear the tenderloin in a hot skillet before adding it to the slow cooker.
However, skipping this step keeps the recipe quick and convenient.
Tips for the Best Crockpot Pork Tenderloin
Don’t confuse pork tenderloin with pork loin
These are two different cuts of pork.
Pork tenderloin is smaller, narrower, and cooks relatively quickly. Pork loin is larger and requires a different cooking approach.
For this recipe, use pork tenderloin.
Use a meat thermometer
A thermometer is the easiest way to avoid guessing.
Check the thickest part of the pork and remove it from the slow cooker once it reaches 145°F.
Let it rest
Resting the pork for at least three minutes after cooking helps keep the slices juicy.
Don’t overcook
This is especially important with tenderloin.
Longer cooking isn’t always better when you’re working with a lean cut.
Slice against the grain
After resting, slice the pork across the grain. This can make each bite feel more tender.
What to Serve With Slow Cooker Pork Tenderloin
This tender pork pairs beautifully with classic comfort-food sides.
Creamy Mashed Potatoes
Mashed potatoes are one of the best choices because they soak up the rich mushroom-onion gravy.
Roasted Vegetables
Try roasted carrots, broccoli, Brussels sprouts, or green beans.
Buttered Egg Noodles
Wide egg noodles make a simple and comforting side for the creamy sauce.
White Rice
Fluffy rice is another easy option for soaking up the savory gravy.
Dinner Rolls
Warm rolls are perfect for enjoying every last bit of sauce.
Apple Slaw
For a lighter contrast, a crisp apple slaw adds freshness and a little sweetness.
Easy Variations
The original recipe keeps things simple with four main ingredients, but you can customize it when you want something different.
Add Mushrooms
Sliced mushrooms can be added to the slow cooker for extra mushroom flavor.
Add Onions
Sliced yellow onions pair beautifully with the onion soup mix and creamy sauce.
Add Garlic
A little minced garlic can add another savory layer.
Add Fresh Herbs
Fresh parsley or thyme can brighten the finished dish.
Add Parmesan
A small amount of grated Parmesan stirred into the sauce after cooking can create an even richer flavor.
These additions are optional and will change the original four-ingredient recipe.
Can I Use Pork Loin Instead?
Pork loin and pork tenderloin are different cuts, so the cooking time will not be the same.
If you use pork loin, you’ll need to adjust the cooking time based on its size and thickness.
For this recipe, pork tenderloin is recommended because it cooks more quickly and works especially well with the creamy sauce.
Can I Use Cream of Chicken Soup?
Yes. If you don’t have cream of mushroom soup, cream of chicken soup can be substituted.
The finished gravy will have a slightly different flavor but will still be creamy and savory.
Can I Make This Recipe Without the Cream Soup?
You can, but you’ll need to change the sauce ingredients and method.
The condensed cream soup is an important part of this particular four-ingredient recipe because it creates the creamy gravy without requiring additional ingredients.
How to Store Leftovers
Let the pork cool before transferring it to an airtight container.
Store the pork and gravy together in the refrigerator for 3–4 days.
Keeping the pork with the sauce helps prevent it from drying out.
How to Reheat Pork Tenderloin
Reheat the pork gently.
Place slices in a covered skillet with some of the gravy over low heat. Add a splash of chicken broth if necessary.
You can also microwave individual portions in short intervals.
Avoid overheating because reheated pork tenderloin can become dry.
Can You Freeze It?
Yes.
Place cooled pork and gravy into a freezer-safe container and freeze for up to about 2–3 months for best quality.
Thaw overnight in the refrigerator before reheating.
For the best texture, reheat gently with some of the gravy.
Frequently Asked Questions
Can I cook pork tenderloin on HIGH?
Yes. Pork tenderloin can be cooked on HIGH, but because it is a lean cut, check it early to prevent overcooking.
How do I know when pork tenderloin is done?
Use an instant-read thermometer in the thickest part of the meat. Pork is ready at 145°F (63°C), followed by a 3-minute rest.
Why did my pork tenderloin become dry?
The most common reason is overcooking. Pork tenderloin is lean and cooks much faster than pork shoulder.
Can I add potatoes?
Yes, but potatoes will add bulk to the slow cooker and may change the cooking time. If you add them, cut them into relatively small, even pieces.
Can I use frozen pork tenderloin?
For food-safety reasons, it is better to start with thawed pork tenderloin in the slow cooker so it reaches a safe temperature predictably.
Can I make this recipe ahead?
Yes. Cook the pork, refrigerate it with the gravy, and gently reheat it when you’re ready to serve.
