Ingredients
You only need 5 main ingredients.
1. Pork Tenderloin
Use 2 pounds pork tenderloin.
Pork tenderloin is a long, narrow, very lean cut of pork. It is naturally tender and cooks much faster than pork shoulder.
Because it is lean, avoid treating it like a large pork roast that needs all-day slow cooking.
2. Cream of Mushroom Soup
Use 1 can, 10.5 ounces, condensed cream of mushroom soup.
This creates the creamy foundation for the gravy and helps keep the pork surrounded by flavorful moisture.
3. Dry Onion Soup Mix
Use 1 packet dry onion soup mix.
The concentrated onion flavor adds seasoning to the sauce without requiring a long list of individual spices.
4. Chicken Broth
Use 1 cup chicken broth.
Chicken broth loosens the condensed soup and creates the savory cooking sauce.
5. Yellow Onion
Use 1 large yellow onion, thinly sliced.
The onion becomes soft and tender as it cooks, adding another layer of savory flavor to the pork and gravy.
How to Make 5-Ingredient Slow Cooker Fall-Apart Pork Tenderloin
This recipe comes together in just a few easy steps.
Step 1: Prepare the Onion
Thinly slice the yellow onion.
Spread about half of the onion across the bottom of the slow cooker.
Step 2: Add the Pork
Pat the pork tenderloin dry with paper towels.
Place it on top of the sliced onions.
If your tenderloin has a visible silver skin, you can trim it away before cooking.
Step 3: Make the Creamy Onion Sauce
In a medium bowl, whisk together:
- Cream of mushroom soup
- Chicken broth
- Dry onion soup mix
Mix until smooth and well combined.
Step 4: Add the Sauce
Pour the creamy onion mixture over the pork tenderloin.
Add the remaining sliced onions around the pork.
Try to coat the tenderloin evenly with the sauce.
Step 5: Slow Cook
Cover the slow cooker.
Cook on LOW for approximately 2 1/2–4 hours.
You can also cook on HIGH for about 1 1/2–2 1/2 hours, but begin checking early.
Cooking time varies depending on the thickness of the tenderloin and the individual slow cooker.
Pork is ready when the center reaches 145°F (63°C), followed by a 3-minute rest.
Because pork tenderloin is lean, avoid leaving it in the slow cooker for many additional hours after it reaches its safe temperature.
Step 6: Rest the Pork
Carefully remove the pork tenderloin from the slow cooker.
Place it on a cutting board and allow it to rest for about 3 minutes.
This gives the juices time to redistribute before slicing.
Step 7: Slice and Serve
Slice the pork into medallions.
Spoon the creamy onion gravy over the top.
For an especially comforting dinner, serve it with mashed potatoes or egg noodles so they can soak up the sauce.
Can Pork Tenderloin Really Become “Fall-Apart” Tender?
Pork tenderloin is naturally tender, but it is different from pork shoulder.
A traditional pulled-pork texture comes from cuts such as pork shoulder that contain more connective tissue and require long cooking.
Pork tenderloin is very lean and can become dry if it is cooked for too long.
For this recipe, the phrase “fall-apart” describes the very tender, easily sliced texture rather than the long-cooked shreddable texture of pork shoulder.
If your goal is truly shreddable pork, pork shoulder is a better cut.
The Most Important Tip: Don’t Overcook Pork Tenderloin
This is the biggest difference between pork tenderloin and many other slow cooker pork recipes.
Pork tenderloin doesn’t need 6–8 hours in the Crockpot.
Because it is lean, extended cooking can cause the meat to lose moisture and become dry.
Start checking the temperature toward the earlier end of the cooking range.
Once the thickest part reaches 145°F (63°C), remove the pork and let it rest for at least three minutes.
An instant-read thermometer is the most reliable way to check.
Should You Brown the Pork First?
You can, but you don’t have to.
Browning the tenderloin in a skillet before adding it to the slow cooker can add additional surface flavor.
However, this recipe is designed to be simple, so skipping the browning step saves time and dishes.
If you choose to brown it, sear the outside briefly over medium-high heat, then transfer the pork to the slow cooker and continue with the recipe.
How to Make the Gravy Extra Smooth
The cream of mushroom soup creates a naturally creamy sauce.
For a smoother gravy, whisk the condensed soup and broth thoroughly before adding the mixture to the slow cooker.
Once the pork is cooked, stir the sauce gently.
If the gravy seems too thick, add a small amount of warm broth.
If it seems too thin, transfer some of the sauce to a saucepan and simmer it gently until it reaches the desired consistency.
What to Serve with Slow Cooker Pork Tenderloin
This pork is especially good with comforting side dishes.
Mashed Potatoes
Creamy mashed potatoes are one of the best choices because they soak up the savory onion gravy.
Egg Noodles
Serve sliced pork and gravy over buttery egg noodles for a cozy family dinner.
Rice
White rice, brown rice, or wild rice can all work well with the creamy sauce.
Green Beans
Steamed green beans provide a simple vegetable side.
Roasted Carrots
Sweet roasted carrots complement the savory onion gravy.
Dinner Rolls
Warm dinner rolls are perfect for catching every bit of the creamy sauce.
Helpful Tips for the Best Pork Tenderloin
Check the Pork Early
Slow cookers vary, and pork tenderloin cooks relatively quickly.
Start checking the internal temperature before the maximum cooking time.
Don’t Confuse Pork Tenderloin with Pork Loin
These are different cuts.
Pork tenderloin is smaller, narrower, and much leaner.
A pork loin roast is larger and may require different cooking times.
Slice Against the Grain
After resting, look at the direction of the muscle fibers and slice across them when possible.
This can make each bite feel more tender.
Don’t Remove All the Sauce
The creamy onion gravy is one of the best parts of the recipe.
Spoon plenty over each serving.
Let the Pork Rest
Even a short rest helps the juices redistribute before slicing.
Easy Variations
The original recipe stays at five main ingredients, but you can customize it when desired.
Add Mushrooms
Fresh sliced mushrooms can intensify the earthy mushroom flavor.
Add Garlic
Fresh minced garlic pairs naturally with pork and onion.
Add Herbs
Thyme, parsley, rosemary, or sage can add an herbal note.
Add Baby Potatoes
Small potatoes can be cooked alongside the pork, although you may need to adjust the arrangement and cooking time.
Use Cream of Chicken Soup
If you don’t enjoy mushrooms, cream of chicken soup can be substituted for a slightly different flavor.
Can You Make This Recipe Ahead?
Yes.
You can prepare the sauce and slice the onion ahead of time.
Keep the prepared ingredients refrigerated until you’re ready to cook.
You can also cook the pork ahead of time and reheat it gently with some of the gravy.
Because pork tenderloin is lean, gentle reheating is important.
How to Store Leftover Pork Tenderloin
Transfer leftover pork and gravy to an airtight container.
Refrigerate for 3–4 days.
Keeping the pork with some gravy helps prevent it from drying out.
How to Reheat Leftovers
Microwave
Place sliced pork in a microwave-safe dish with some gravy.
Cover loosely and heat in short intervals until hot.
Stovetop
Place the pork and gravy in a skillet over low heat.
Cover and warm gently.
Avoid boiling the gravy or aggressively heating the pork.
Oven
Place the pork in a baking dish with some gravy.
Cover with foil and warm gently until heated through.
Can You Freeze Pork Tenderloin?
Yes, although the texture may be slightly different after thawing and reheating.
For best results, freeze the pork together with some of the gravy.
Store in an airtight freezer-safe container.
Thaw in the refrigerator before reheating gently.
Frequently Asked Questions
Can I use pork loin instead of pork tenderloin?
Yes, but pork loin is a different cut and is larger and thicker. Cooking time will need to be adjusted, and an instant-read thermometer is recommended.
Can I use pork shoulder?
You can, but pork shoulder requires a completely different cooking approach and much longer cooking time. It is better suited to pulled pork.
Can I cook pork tenderloin all day?
It is not recommended. Pork tenderloin is lean and can become dry if left cooking for many hours.
What temperature should pork tenderloin reach?
Cook pork tenderloin to 145°F (63°C) in the thickest part, then let it rest for at least 3 minutes.
Can I use cream of chicken soup?
Yes. It can replace cream of mushroom soup if preferred.
Can I add potatoes?
Yes. Small potatoes can make the meal more complete, although they are not part of the original five-ingredient recipe.
Why is my pork dry?
The most common reason is overcooking. Pork tenderloin is lean, so begin checking the temperature early.
Can I shred pork tenderloin?
You can, but pork tenderloin is better suited to slicing. If you want traditional shreddable pork, use pork shoulder instead.
