- Mushrooms: 8 ounces, cremini or button, sliced. Fresh is best for optimal flavor and texture.
- Spinach: 5 ounces, fresh, baby spinach. If using frozen, make sure to thaw it completely and squeeze out any excess water.
- Onion: 1 medium, finely chopped. Adds a touch of sweetness and depth.
- Garlic: 2-3 cloves, minced. Because everything is better with garlic, right?
- Olive Oil: 2 tablespoons. For sautéing the vegetables and searing the pork.
- Parmesan Cheese: 1/4 cup, grated. Adds a salty, nutty flavor to the stuffing.
- Breadcrumbs: 1/4 cup, plain or Italian seasoned. Helps bind the stuffing together.
- Dried Herbs: 1 teaspoon Italian seasoning, 1/2 teaspoon dried thyme, 1/4 teaspoon dried rosemary. Feel free to experiment with your favorite herb combinations.
- Salt and Pepper: To taste. Don’t be shy!
- Optional: A splash of white wine for deglazing the pan. Adds a lovely depth of flavor, but it’s not essential.
Step-by-Step Instructions: Let’s Get Cooking!
Alright, let’s get down to business. Here’s a detailed guide to making your very own Spinach Mushroom Stuffed Pork Tenderloin:
Step 1: Prep the Pork
First things first, let’s get that pork tenderloin ready. Pat it dry with paper towels. This is crucial for getting a good sear later on. Now, using a sharp knife, carefully butterfly the tenderloin. To do this, slice the tenderloin lengthwise, but don’t cut all the way through. Open it up like a book. Place a piece of plastic wrap over the butterflied pork and use a meat mallet (or a rolling pin in a pinch) to gently pound it to an even thickness of about 1/2 inch. This will help it cook evenly and make it easier to roll up.
Step 2: Sauté the Vegetables
Heat the olive oil in a large skillet over medium heat. Add the chopped onion and cook until softened, about 5 minutes. Add the minced garlic and cook for another minute until fragrant. Be careful not to burn the garlic! Add the sliced mushrooms and cook until they release their liquid and start to brown, about 8-10 minutes. This is where Air Fryer Mushroom Perfection comes in handy, but for the stuffing, sautéing them is ideal. Finally, add the spinach and cook until it wilts, about 2-3 minutes. Season with salt and pepper to taste.
Step 3: Assemble the Stuffing
Remove the skillet from the heat and let the vegetable mixture cool slightly. In a large bowl, combine the sautéed vegetables, Parmesan cheese, breadcrumbs, Italian seasoning, thyme, and rosemary. Mix well until everything is evenly combined. Taste and adjust the seasoning as needed. Remember, you can always add more, but you can’t take it away!
Step 4: Stuff and Roll
Spread the spinach mushroom mixture evenly over the butterflied pork tenderloin, leaving a small border around the edges. Starting from one end, carefully roll up the tenderloin into a tight log. Use kitchen twine to tie the tenderloin in several places to secure the stuffing. This will prevent it from unraveling during cooking.
Step 5: Sear the Pork
Heat a tablespoon of olive oil in a large oven-safe skillet (cast iron is ideal) over medium-high heat. Sear the stuffed pork tenderloin on all sides until it’s nicely browned, about 2-3 minutes per side. This step is crucial for developing a flavorful crust and locking in the juices. If you are looking for just searing pork, consider making Garlic Butter Pan Seared Pork Chops.
Step 6: Bake to Perfection
Transfer the skillet to a preheated oven at 375°F (190°C). Bake for 20-25 minutes, or until the internal temperature of the pork reaches 145°F (63°C). Use a meat thermometer to ensure accuracy. Overcooked pork can be dry and tough, so it’s important to get this right.
Step 7: Rest and Slice
Remove the skillet from the oven and let the pork tenderloin rest for 10-15 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful final product. Remove the kitchen twine and slice the tenderloin into 1-inch thick medallions. Serve immediately and prepare to be amazed!
Tips and Tricks for Stuffed Meat Success
Okay, let’s talk about some insider tips that will help you nail this recipe:
- Don’t Overstuff: It’s tempting to pack the pork tenderloin with as much stuffing as possible, but resist the urge! Overstuffing can cause the tenderloin to burst during cooking.
- Secure it Well: Make sure to tie the tenderloin tightly with kitchen twine to prevent the stuffing from falling out.
- Sear it Hot: A good sear is essential for developing flavor and locking in moisture. Make sure your skillet is hot before adding the pork.
- Don’t Overcook: Pork tenderloin is best served medium-rare to medium. Use a meat thermometer to ensure it’s cooked to the correct internal temperature.
- Let it Rest: Resting the pork before slicing is crucial for allowing the juices to redistribute. Don’t skip this step!
Variations and Substitutions
Want to put your own spin on this recipe? Here are some ideas:
- Cheese, Please: Experiment with different types of cheese in the stuffing. Goat cheese, feta, or mozzarella would all be delicious.
- Add Some Heat: Add a pinch of red pepper flakes to the stuffing for a spicy kick.
- Sweetness Overload: Add some Caramelized Onions to the stuffing.
- Get Fruity: Add dried cranberries or chopped apples to the stuffing for a touch of sweetness and tartness.
- Veggie Power: Add other vegetables to the stuffing, such as bell peppers, zucchini, or carrots. Think of this as the inside-out version of Stuffed Bell Peppers.

- Sauce it Up: Serve the sliced pork tenderloin with a delicious sauce, such as a mushroom cream sauce, a balsamic glaze, or a Dijon mustard sauce.
Serving Suggestions

- Roasted Vegetables: Roasted asparagus, broccoli, or Brussels sprouts would all be excellent choices.
- Mashed Potatoes: Creamy mashed potatoes are always a crowd-pleaser.
- Quinoa or Rice: For a healthier option, serve with quinoa or brown rice.

Is This Dish a Low Carb Dinner?
Absolutely! While the breadcrumbs contribute some carbohydrates, the overall carb count in this recipe is relatively low, especially if you’re mindful of your portion sizes. The pork tenderloin itself is a lean protein source, and the spinach and mushrooms are low in carbs and high in nutrients. To make it even more low-carb friendly, you can:
- Use Almond Flour: Substitute almond flour for the breadcrumbs in the stuffing.
- Increase Vegetables: Add more low-carb vegetables to the stuffing, such as cauliflower rice or chopped celery.
- Serve with Low-Carb Sides: Pair the pork tenderloin with low-carb side dishes, such as roasted cauliflower, zucchini noodles, or a salad with a low-carb dressing.
Storing and Reheating Leftovers
If you have any leftovers (which is unlikely, but possible!), store them in an airtight container in the refrigerator for up to 3 days. To reheat, you can:
- Microwave: Microwave the sliced pork tenderloin on medium power until heated through. Be careful not to overheat it, as this can make it dry.
- Oven: Reheat the sliced pork tenderloin in a preheated oven at 350°F (175°C) until heated through. This will take longer than microwaving, but it will help retain the moisture.
- Skillet: Reheat the sliced pork tenderloin in a skillet over medium heat with a little bit of olive oil. This is a great way to revive the crust and add some extra flavor.
