Ingredients

• 1½ to 2 pounds pork tenderloin, trimmed
• 1 (1-ounce) packet dry onion soup mix

• 1 cup low-sodium beef broth or water

Instructions

6. Transfer the pork to a cutting board and let it rest for 5 minutes.
7. Stir the gravy in the slow cooker until smooth and well blended.
8. Slice the pork into 1/2-inch thick medallions.
9. Return the pork slices to the slow cooker and gently toss them in the onion gravy.
10. Serve warm with plenty of gravy spooned over the top.

Serving Suggestions

This pork tenderloin is delicious served over creamy mashed potatoes, buttered egg noodles, white rice, or cauliflower rice. Pair it with green beans, roasted broccoli, glazed carrots, or a simple garden salad for a complete meal.

Leftovers are fantastic on toasted bread as an open-faced sandwich topped with warm onion gravy.

Variations

• Extra Onion Flavor: Add one thinly sliced yellow onion beneath the pork before cooking.
• Creamier Gravy: Stir in 2 to 3 tablespoons of sour cream just before serving.
• Different Soup Options: Substitute cream of celery or cream of chicken soup for the mushroom soup.
• Thicker Gravy: Mix 1 tablespoon cornstarch with 2 tablespoons cold water and stir into the gravy during the last 15 minutes of cooking.
• Pork Loin Version: Use pork loin instead of tenderloin and increase the cooking time as needed.

Storage

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat until the pork reaches 165°F before serving.

For longer storage, freeze the pork and gravy in freezer-safe containers for up to 3 months. Thaw overnight in the refrigerator before reheating.

Helpful Tips

• Always use fully thawed pork for safe slow cooker cooking.
• Keep the lid closed as much as possible during cooking.
• Allow the pork to rest before slicing to help retain moisture.
• Use a meat thermometer to ensure proper doneness.
• Return the sliced pork to the gravy before serving for maximum flavor.

Food Safety Notes

• Cook pork to a minimum internal temperature of 145°F.
• Refrigerate leftovers within 2 hours of cooking.
• Store leftovers in shallow containers for quicker cooling.
• Reheat leftovers to 165°F before serving.
• Do not cook frozen pork directly in a slow cooker.
