How to Make Mushroom, Spinach & Gruyère Stuffed Pork Tenderloin

Preheat the oven to 400°F (200°C). This ensures that your tenderloin cooks evenly and achieves a perfect golden-brown exterior.
Sauté the bacon in a skillet with 1 tablespoon of olive oil over medium heat until it’s crispy. Then, add the chopped cremini mushrooms and diced yellow onion, cooking until softened and fragrant.
Mix in minced garlic, fresh thyme, and baby spinach, continuing to cook until the spinach wilts. Pour in the dry white wine, allowing it to reduce for a couple of minutes before removing from heat. Stir in the Gruyère cheese until melted and combined.
Prepare the pork tenderloin by trimming any excess fat and butterflying it. Fill the center with the savory mushroom-spinach mixture, then roll it carefully and secure it with kitchen twine.
Sear the stuffed tenderloin in the same skillet on all sides until browned. This seals in juices and adds flavor, then transfer to the oven and bake for about 30 minutes, or until the internal temperature reaches 145°F (63°C).
Rest the pork for 5-10 minutes before slicing. This allows the juices to redistribute, ensuring each slice is tender. Garnish with fresh parsley for that vibrant finishing touch!

Optional: Serve with jeweled saffron rice for a delightful side dish.

Mushroom, Spinach & Gruyère Stuffed Pork Tenderloin Recipe FAQs

How do I choose the right mushrooms for this recipe?
For the best flavor, I recommend using cremini mushrooms, as they provide a robust earthiness. If they’re unavailable, feel free to substitute with white button mushrooms. Choose mushrooms that are firm, unblemished, and have a pleasant, earthy aroma. Avoid any with dark spots or sliminess.

How should I store leftover stuffed pork tenderloin?
Absolutely! After enjoying your meal, store the leftover stuffed pork tenderloin in an airtight container in the refrigerator for up to 3 days. Make sure it cools completely before sealing it. When reheating, you can gently warm it in the oven to keep the meat juicy and the filling creamy.

Can I freeze Mushroom, Spinach & Gruyère Stuffed Pork Tenderloin?
Yes, you can freeze it for future enjoyment! Wrap the stuffed pork tenderloin tightly in plastic wrap, then cover it with aluminum foil to protect it from freezer burn. It can be frozen for up to 3 months. When you’re ready to savor it again, allow it to thaw overnight in the refrigerator before reheating.

What should I do if my pork tenderloin cooks too quickly?
Don’t worry! If you notice the outer layer browning too quickly while cooking, you can reduce the oven temperature to 375°F (190°C) and continue cooking until it reaches the recommended internal temperature of 145°F (63°C). Always use a meat thermometer for accuracy—a must-have tool in your kitchen!

Are there any dietary considerations for this recipe?
Great question! This dish contains pork and cheese, which may not be suitable for specific diets or individuals with allergies. If preparing for guests, consider alternatives such as substituting turkey breast for the pork or using dairy-free cheese. Double-check ingredient labels, especially for those with lactose intolerance or gluten sensitivities.

How can I make this recipe more flavorful?
For an intense flavor boost, add grated Parmesan cheese to your mushroom-spinach filling. This addition complements the Gruyère beautifully. Also, consider using fresh herbs or even a dash of lemon juice to brighten up the flavors. Cooking is all about discovery, so feel free to experiment!
