How to Make Slow Cooker Pork Tenderloin with Mushroom Onion Gravy
Step 1: Prepare the Pork
Remove the pork tenderloin from its packaging and pat it dry with paper towels. Trim away any excess silver skin or visible tough connective tissue.
Place the tenderloin in the bottom of your slow cooker.
Step 2: Make the Mushroom Onion Gravy
In a medium bowl, combine the cream of mushroom soup, dry onion soup mix, and beef broth. Stir until everything is evenly mixed.
The mixture will be thick and full of savory flavor.
Step 3: Add the Gravy
Pour the mushroom onion mixture over the pork tenderloin, spreading it evenly so the meat is coated.
Step 4: Slow Cook
Cover and cook until the pork reaches an internal temperature of 145°F (63°C), followed by a 3-minute rest.
- LOW: Approximately 2½–4 hours
- HIGH: Approximately 1½–2½ hours
Cooking times vary depending on the size and thickness of the tenderloin and your slow cooker. Begin checking the temperature early because pork tenderloin is lean and can dry out if overcooked.
Step 5: Rest and Serve
Carefully remove the pork tenderloin and let it rest for 3 minutes before slicing.
Slice into medallions and arrange on a serving platter. Spoon the warm mushroom onion gravy generously over the pork.
Enjoy every tender, savory bite!
Tips for the Best Pork Tenderloin
- Don’t confuse tenderloin with pork loin: Pork tenderloin is smaller and cooks much faster, so cooking times are different.
- Use a meat thermometer: This is the best way to avoid overcooking lean pork.
- Don’t skip the resting time: A short rest helps the juices settle before slicing.
- Whisk the gravy well: Mixing the ingredients before adding them creates a more even sauce.
- Want thicker gravy? Transfer the cooking liquid to a saucepan and simmer with a cornstarch slurry until thickened.
What to Serve With Pork Tenderloin and Mushroom Onion Gravy
This comforting dinner pairs perfectly with:
- Creamy mashed potatoes
- Buttered egg noodles
- Steamed white rice
- Roasted baby potatoes
- Garlic green beans
- Steamed broccoli
- Roasted carrots
- Warm dinner rolls
Mashed potatoes or egg noodles are especially delicious because they soak up every bit of the mushroom onion gravy.
Easy Recipe Variations
Add Fresh Mushrooms: Stir sliced mushrooms into the slow cooker for extra texture and earthy flavor.
Add Garlic: A little minced garlic can give the gravy an extra savory touch.
Make It Creamier: Stir in a splash of heavy cream near the end of cooking.
Add Fresh Herbs: Sprinkle chopped parsley or thyme over the finished pork before serving.
Frequently Asked Questions
Can I use pork loin instead of pork tenderloin?
Yes, but pork loin is a larger and thicker cut of meat. It will require a different cooking time, so always use a meat thermometer and cook until it reaches 145°F (63°C), followed by a 3-minute rest.
Why is my pork tenderloin dry?
Pork tenderloin is naturally lean. Cooking it for too long can make it dry and tough. Check the internal temperature early and remove it once it reaches 145°F (63°C).
Can I use fresh mushrooms instead of cream of mushroom soup?
Fresh mushrooms can add great flavor, but they won’t provide the same creamy gravy. If you replace the soup, you’ll need another creamy sauce ingredient to maintain the recipe’s texture.
Can I prepare this recipe ahead of time?
Yes. You can mix the gravy ingredients ahead of time and refrigerate them in a covered container. Keep the raw pork refrigerated separately until you’re ready to cook.
How do I store leftovers?
Allow the pork and gravy to cool, then place them in an airtight container. Refrigerate for up to 3–4 days.
Can I freeze the leftovers?
Yes. Store the sliced pork with plenty of gravy in a freezer-safe container for up to 2–3 months for best quality. Thaw overnight in the refrigerator before reheating.
