The 5-Star Ingredients

This recipe proves that you don’t need a long ingredient list to create something spectacular. Here’s what you’ll need:

Pork tenderloin – 1 whole, about 1½ to 2 pounds. Pork tenderloin is a lean, tender cut that cooks beautifully in the slow cooker. It stays juicy and flavorful, and it slices perfectly for serving.

Dry onion soup mix – 1 packet (about 1 ounce). Onion soup mix adds savory onion flavor, garlic, herbs, and depth that transforms the simple gravy into something rich and complex.

Cream of mushroom soup – 1 can (10.5 ounces). Cream of mushroom soup creates the rich, creamy base of the gravy. It adds savory depth and a velvety texture.

Chicken broth – ½ cup. Chicken broth provides the liquid base for the gravy and adds savory flavor.

Worcestershire sauce – 1 tablespoon. Worcestershire sauce adds tangy, umami depth that balances the richness of the soup.

That’s it. Five ingredients. No chopping vegetables. No complicated steps. Just honest, delicious ingredients that come together beautifully.

Step-by-Step Instructions (The Short Version)

Lightly coat the slow cooker insert with cooking spray if desired. Place the raw whole pork tenderloin in the bottom of the slow cooker.
In a medium bowl, stir together the dry onion soup mix, cream of mushroom soup, chicken broth, and Worcestershire sauce until combined.
Pour the sauce mixture over the pork tenderloin, making sure the top is well coated. Cover and cook on LOW for 4 to 5 hours, or until the pork is tender and reaches a safe internal temperature.
Transfer the cooked tenderloin to a cutting board and let it rest for 5 minutes. If you want a thicker gravy, whisk the juices in the slow cooker until smooth and serve them as-is or simmer them briefly on the stove to reduce slightly.
Slice the pork into medallions and spoon the gravy over the top before serving.

How to Serve It Like a Pro

This tenderloin is delicious on its own, but a few simple sides make it a complete meal:

Over mashed potatoes – Creamy potatoes soak up all that rich gravy.
Over rice – A simple and satisfying bed for the pork and gravy.
Over egg noodles – Wide noodles are perfect for catching every drop of sauce.
With roasted vegetables – Green beans, carrots, or broccoli add color and nutrition.
With a side salad – A crisp green salad cuts through the richness.
With crusty bread – For soaking up every last bit of gravy.
With a sprinkle of fresh parsley – Adds brightness and color.
With a dollop of sour cream – Adds tanginess and creaminess.

Pro Tips for Absolute Success

After making this tenderloin multiple times (because it’s so easy and delicious), here are my best tips:

Don’t add extra liquid. The pork releases its own juices as it cooks.
Don’t lift the lid during cooking. The heat and moisture need to stay consistent.
Check the internal temperature. Pork should reach 145°F for safety.
Let it rest before slicing. A 5-minute rest allows the juices to redistribute.
Spoon the gravy over the slices. This adds extra flavor.
Simmer the gravy for a thicker consistency. A quick reduction adds richness.
Serve warm. This is best enjoyed hot and fresh.
