Ingredients You’ll Need
For the Stuffed Pork Tenderloin:
- Pork Tenderloin: 2 pounds (trimmed and butterflied for stuffing)
- Mushrooms: 1 cup (finely chopped; use button, cremini, or a mix for depth)
- Fresh Spinach: 2 cups (chopped; adds a burst of color and nutrients)
- Gruyère Cheese: 1 cup (shredded; for a creamy, nutty flavor)
- Garlic: 2 cloves (minced; infuses a subtle aromatic kick)
- Shallot: 1 (finely chopped; adds a mild sweetness)
- Olive Oil: 2 tablespoons (for sautéing and searing)
- Salt and Black Pepper: 1 teaspoon each (adjust to taste)
- Dijon Mustard: 2 tablespoons (brings a hint of tanginess)
- Fresh Thyme: 1 teaspoon (chopped; optional but highly recommended)
- Paprika: 1/2 teaspoon (optional, for added color and mild spice)
For the Sauce:
- Chicken Stock: 1 cup (provides a flavorful base)
- Dry White Wine: 1/2 cup (adds acidity and depth)
- Butter: 2 tablespoons (for richness)
- All-Purpose Flour: 1 tablespoon (for thickening)
Step-by-Step Directions
Step 1: Prepare the Pork Tenderloin
- Preheat the oven to 375°F (190°C).
- Butterfly the tenderloin by slicing it lengthwise. Be careful not to cut all the way through; the goal is to open it like a book. Place it between two pieces of plastic wrap and use a meat mallet to gently flatten it to an even thickness (about 1/2 inch).
- Season the interior with half the salt, pepper, and thyme. This ensures every bite of the tenderloin is flavorful.
Step 2: Make the Filling
- Heat 1 tablespoon of olive oil in a large skillet over medium heat.
- Add the chopped shallot and garlic, cooking until they are fragrant and softened (about 2 minutes).
- Add the mushrooms and cook for 5-7 minutes, stirring occasionally, until they release their moisture and begin to brown.
- Stir in the chopped spinach and cook for 2-3 minutes, or until wilted.
- Remove the skillet from heat and stir in the shredded Gruyère cheese and Dijon mustard. Mix until the cheese melts and the filling is well combined.
- Allow the filling to cool slightly before using.
Step 3: Assemble the Tenderloin
- Spread the prepared filling evenly over the butterflied tenderloin, leaving about 1/2 inch of space around the edges.
- Starting from one long side, roll the tenderloin tightly into a cylinder.
- Secure the roll with kitchen twine, tying at 2-inch intervals to ensure it holds its shape during cooking.
- Rub the outside with the remaining salt, pepper, and paprika (if using) for a flavorful crust.
Step 4: Sear and Roast
- Heat the remaining tablespoon of olive oil in an oven-safe skillet over medium-high heat.
- Sear the stuffed tenderloin on all sides until golden brown, about 3 minutes per side. This step locks in the juices and creates a flavorful crust.
- Transfer the skillet to the preheated oven and roast for 25-30 minutes, or until the internal temperature reaches 145°F (63°C) when measured with a meat thermometer.
- Remove the skillet from the oven and transfer the pork to a cutting board. Cover loosely with foil and let it rest for 10 minutes to retain its juices.
Step 5: Make the Sauce
- Place the skillet back on the stovetop over medium heat. Add the butter and let it melt.
- Stir in the flour, whisking constantly to form a roux. Cook for about 1 minute until lightly golden.
- Gradually add the white wine, scraping up any browned bits from the skillet. This step adds incredible depth to the sauce.
- Stir in the chicken stock and simmer until the sauce thickens, about 3-4 minutes.
- Taste and adjust seasoning with salt and pepper as needed.
Step 6: Slice and Serve
- Remove the kitchen twine from the tenderloin and slice it into medallions, about 1-inch thick.
- Arrange the slices on a serving platter and drizzle with the prepared sauce.
- Garnish with fresh thyme or parsley for a touch of color and freshness.

Variations to Try
- Vegetarian Twist: Swap out the pork and use large portobello mushrooms or thick eggplant slices to create a vegetarian-friendly stuffed entrée.
- Alternative Cheeses: Replace Gruyère with sharp cheddar, Havarti, or mozzarella for a slightly different flavor profile.
- Add a Sweet Note: Incorporate dried cranberries or caramelized onions into the filling for a hint of sweetness that complements the savory elements.
- Add Crunch: Sprinkle toasted pine nuts or walnuts into the filling for a delightful crunch.
- Herb Variations: Experiment with rosemary, sage, or oregano to customize the dish to your taste.
Storage and Reheating Tips
- Storage: Store leftover pork tenderloin in an airtight container in the refrigerator for up to 3 days.
- Freezing: You can freeze the cooked tenderloin by wrapping it tightly in plastic wrap and placing it in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator before reheating.
- Reheating: To reheat, slice the pork and warm it in a 350°F (175°C) oven, covered with foil, for 10-15 minutes. Avoid microwaving, as it can dry out the pork.
