Pork Tenderloin Roulade With Porcini Mushroom Sauce

My first encounter with a roulade was in my grandmother’s kitchen. The aroma of simmering mushrooms and herbs hung heavy in the air as she meticulously layered thinly sliced prosciutto and provolone inside a flattened chicken breast. It was a Sunday tradition, a labor of love that transformed humble ingredients into an elegant centerpiece. Years later, while competing in the Maggiano’s Italian cook contest, I adapted her technique using pork tenderloin and a rich porcini mushroom sauce, a dish that captured the essence of Italian comfort food with a touch of sophistication.

Recipe Overview

• Prep Time: 30 minutes
• Cook Time: 30 minutes
• Total Time: 60 minutes
• Servings: 4-6
• Dietary Type: Not Gluten-Free

Ingredients

• 1 large pork tenderloin
• ½ cup butter, room temperature
• 1 tablespoon white truffle oil
• ¼ lb mortadella, sliced thin
• ¼ lb Fontina cheese
• ½ cup flour
• ¼ cup extra virgin olive oil (EVOO)
• 1 shallot, minced
• 2 tablespoons flour
• 1 cup dry red wine
• ⅓ lb assorted mushrooms, sliced
• ½ ounce dried porcini mushrooms (soaked in ½ cup warm water)

Equipment Needed

• Oven
• Large saute pan
• Meat mallet
• Butcher’s twine
• Thermometer
• Tin foil

Instructions

1. Preheat your oven to 325°F (160°C). This lower temperature will ensure the pork cooks evenly and remains tender.

2. Butterfly the pork tenderloin. To do this, place the tenderloin on a cutting board and use a sharp knife to slice it horizontally along one side, stopping about ½ inch from the other side. Open it like a book.

3. Flatten the butterflied tenderloin with a meat mallet until it’s approximately ¼ inch thick. Aim for a roughly rectangular shape, about 12 inches by 8 inches. This ensures even cooking and a uniform roulade.

4. In a small bowl, blend the softened butter with the white truffle oil. Divide this mixture in half. Place half of the truffle butter in the refrigerator to firm up; this will be used later for finishing the dish.

5. Lay out the flattened pork tenderloin. Spread the remaining half of the truffle butter evenly over the surface.

6. Layer the mortadella slices and Fontina cheese over the buttered pork, leaving a 1-inch border around the edges. This prevents the filling from spilling out during rolling.

7. With the long side facing you, roll the pork tenderloin tightly into a cylinder.

8. Secure the roulade by tying it with butcher’s twine at intervals of about 2 inches. This helps the roulade maintain its shape during cooking.

9. Dredge the rolled and tied tenderloin in flour, ensuring it’s lightly and evenly coated. This will help with browning and create a slightly thickened sauce.

10. Heat the extra virgin olive oil (EVOO) in a large saute pan over medium-high heat. The pan should be large enough to accommodate the entire roulade.

11. Sear the tenderloin on all sides until it is nicely browned. This creates a flavorful crust and adds depth to the final dish.

12. Remove the seared loin from the saute pan and place it in the preheated oven.

13. While the pork is in the oven, prepare the sauce. In the same saute pan (don’t clean it!), add the minced shallots and cook until they are soft and translucent.

14. Add the 2 tablespoons of flour to the shallots and cook until a smooth paste forms, stirring constantly. This creates a roux, which will thicken the sauce.

15. Deglaze the pan by adding the dry red wine. Scrape up any browned bits from the bottom of the pan to incorporate that flavor into the sauce.

16. Add the assorted mushrooms to the pan and saute until their moisture is reduced, about 5 minutes. This concentrates their flavor.

17. Add the porcini mushrooms along with their soaking liquid to the pan. Be careful not to pour any grit that may have settled at the bottom of the soaking liquid into the pan. Simmer until the sauce has slightly thickened.

18. Check the internal temperature of the tenderloin using a thermometer. Remove it from the oven when it registers 155°F (68°C).

19. Let the tenderloin rest for 10 minutes, loosely covered with tin foil. This allows the juices to redistribute, resulting in a more tender and flavorful final product.

20. Remove the string from the tenderloin and slice it on the diagonal into medallions.

21. Serve the sliced tenderloin on a platter, drizzled generously with the porcini mushroom sauce. For an extra touch of richness, dot the platter with the reserved chilled truffle butter.

Expert Tips & Tricks

• To ensure the pork tenderloin is evenly flattened, place it between two sheets of plastic wrap before using the meat mallet.
• If you don’t have mortadella, prosciutto or even ham can be substituted. Similarly, any good melting cheese like Gruyere or Provolone will work in place of the Fontina.
• For a deeper mushroom flavor, use a mix of wild mushrooms like shiitake, cremini, and oyster mushrooms in addition to or instead of the assorted mushrooms.
• Make-ahead tip: The roulade can be assembled and refrigerated (uncooked) up to 24 hours in advance. Add about 10-15 minutes to the cooking time if cooking straight from the fridge.
• If the sauce becomes too thick, add a little chicken broth or water to thin it out.

Serving & Storage Suggestions

Serve the Pork Tenderloin Roulade with Porcini Mushroom Sauce immediately after slicing for the best flavor and texture. It pairs beautifully with roasted vegetables like asparagus or Brussels sprouts, creamy polenta, or a simple green salad. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm the slices in a skillet over medium heat with a little of the sauce, or microwave on low power. Freezing is not recommended as the texture of the pork and the sauce may be affected.

Variations & Substitutions

• For a gluten-free version, use a gluten-free flour blend for dredging the pork. You may also need to ensure your red wine is gluten-free (some wines are clarified using gluten-based products).
• Add spinach or sun-dried tomatoes to the filling for extra color and flavor.
• Substitute Marsala wine for the red wine in the sauce for a sweeter, richer flavor.
• Experiment with different cheeses in the filling, such as mozzarella, provolone, or asiago.

FAQs (Frequently Asked Questions):

Q: Can I use a different cut of pork for this recipe?
A: While pork tenderloin is the ideal cut due to its tenderness and size, you could potentially use a pork loin roast, but it will require more flattening and may be a bit drier.

Q: How do I prevent the roulade from falling apart while cooking?
A: Make sure to roll the tenderloin tightly and secure it well with butcher’s twine. Also, searing it before baking helps to seal in the juices and maintain its shape.

Q: Can I make the sauce ahead of time?
A: Yes, the porcini mushroom sauce can be made a day in advance. Store it in an airtight container in the refrigerator and reheat gently before serving.

Q: What if I don’t have white truffle oil?
A: If you don’t have truffle oil, you can simply omit it or substitute it with a small amount of regular olive oil. The truffle oil adds a luxurious touch, but the dish will still be delicious without it.

Q: How do I know when the pork is cooked through?
A: The best way to ensure the pork is cooked to a safe internal temperature is to use a meat thermometer. Aim for 155°F (68°C), as the temperature will continue to rise slightly as it rests.
