Ingredients

  • 1.5–2 lbs pork tenderloin, cut into 1-inch medallions

  • 1 packet (1 oz) dry Italian zesty seasoning mix
  • 1 cup shredded mozzarella cheese

How to Make Slow Cooker Creamy Garlic Parmesan Pork Tenderloin

1. Add the Pork

Arrange the raw pork tenderloin medallions evenly across the bottom of your slow cooker.

Try to keep the pieces in a relatively even layer so they cook consistently.

2. Add the Mushrooms

Scatter the sliced white button mushrooms directly over the pork medallions.

As the mushrooms cook, they soften and release moisture and savory flavor into the creamy sauce.

3. Season Everything

Sprinkle the dry Italian zesty seasoning mix evenly over the mushrooms and pork. This adds a flavorful blend of herbs and seasonings without requiring several individual spices.

4. Add the Creamy Sauce

Pour the creamy garlic Parmesan sauce over everything, making sure the pork is well coated.

If using Alfredo sauce instead, the result will still be rich and creamy with a slightly different flavor profile.

5. Slow Cook

Cover and cook on LOW for 3.5–4.5 hours or HIGH for 2–2.5 hours, until the pork is tender and juicy.

Because pork tenderloin is a lean cut, avoid cooking it significantly longer than necessary. Cooking time can vary depending on the thickness of the medallions and your slow cooker.

6. Add the Cheese

Once the pork is cooked, sprinkle the shredded mozzarella evenly over the top.

Cover the slow cooker again and let it stand for about 5 minutes, or until the mozzarella is melted and creamy.

7. Serve

Serve the creamy pork and mushroom mixture hot over penne pasta or alongside warm garlic bread.

Make sure to spoon plenty of the creamy garlic Parmesan sauce over the pasta for maximum flavor.

Helpful Tips

Cut the medallions evenly. Keeping the pork pieces close to 1 inch thick helps them cook more consistently.

Don’t overcook pork tenderloin. Unlike pork shoulder, tenderloin is lean and doesn’t require hours of cooking to become tender. Check it toward the end of the suggested cooking time.

Use fresh mushrooms. White button mushrooms are convenient and mild, allowing the garlic Parmesan and Italian seasoning to remain the dominant flavors.

Taste before adding salt. The Italian seasoning mix and prepared creamy sauce may already contain salt, so taste the finished dish before adding more.

Let the cheese melt with the lid closed. Five minutes with the slow cooker covered should allow the mozzarella to melt over the hot pork and sauce.

Serving Ideas

This creamy pork tenderloin is especially delicious served over pasta. Penne works well because its shape holds onto the rich garlic Parmesan sauce.

You can also serve it with:

  • Garlic bread
  • Roasted broccoli
  • Steamed green beans
  • A simple garden salad
  • Roasted asparagus
  • Buttered vegetables

For an extra Italian-inspired dinner, add a fresh salad and warm garlic bread alongside the creamy pork.

Leftovers

Store leftover pork, mushrooms, and sauce in an airtight container in the refrigerator. Keep the pasta separate when possible so it doesn’t absorb all of the sauce during storage.

When reheating, gently warm the pork and sauce and add a small splash of milk, broth, or water if the sauce has thickened too much.

Food Safety Note

Keep raw pork refrigerated until you’re ready to prepare it. Use a food thermometer to verify that the pork reaches at least 145°F (63°C), followed by a short rest. Refrigerate leftovers promptly and reheat thoroughly before serving.

Final Thoughts

This Slow Cooker Creamy Garlic Parmesan Pork Tenderloin combines tender pork, earthy mushrooms, creamy garlic Parmesan sauce, Italian seasoning, and melted mozzarella into one comforting meal.

The slow cooker keeps preparation simple while allowing the flavors to come together beautifully. Serve the finished dish over penne pasta or with garlic bread to soak up the creamy sauce, and you have an easy dinner that’s rich, satisfying, and full of flavor.
