This blue cheese stuffed pork tenderloin recipe transforms a simple cut into a showstopping centerpiece with creamy blue cheese pockets and tender meat that melts in your mouth. After years of perfecting pork techniques at The Smoky Pig, I developed this method that combines restaurant-quality stuffing with home-cooking simplicity. The secret lies in the timing—cooking the pork just until it hits 145°F before resting, ensuring every bite stays juicy while the blue cheese maintains its perfect texture.
The process starts with butterflying the tenderloin and creating pockets for the blue cheese filling, which I like to mix with a touch of Dijon mustard for brightness and walnuts for bold crunch. Roasting at 425°F for just 20 minutes after stuffing ensures the exterior gets beautifully browned while the interior stays moist. This isn't your average pork recipe—it's a technique I've refined through hundreds of pounds of pork, balancing rich blue cheese with the natural sweetness of the meat.
What you'll end up with is a pork tenderloin that's restaurant-quality—golden on the outside, tender throughout, and packed with pockets of creamy blue cheese that add a sophisticated twist. The walnuts provide texture contrast, while the mustard brightens the richness. This dish pairs beautifully with roasted root vegetables or a crisp apple salad, making it perfect for dinner parties or special occasions.
One of the things I love about this recipe is how it showcases pork's natural qualities while adding a gourmet touch without complication. The blue cheese stuffing elevates what could be a simple roast into something memorable, and the technique is straightforward enough for home cooks to master. Let's get cooking—this pork tenderloin will be the star of your table.

| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🐖 | 1 ½ lb | Center-cut, even thickness |
| Blue Cheese Crumbles 🧀 | 8 oz | Stilton or Gorgonzola preferred |
| Dijon Mustard 🍯 | 1 tbsp | High-quality, smooth variety |
| Walnuts 🌰 | ½ cup | Toasted, roughly chopped |

The pork tenderloin is where this dish shines—center-cut and even thickness ensures perfect cooking. Whole Foods or local butchers often carry the best quality, but any well-marbled tenderloin works. Look for a piece with minimal connective tissue, and pat it dry before butterflying. The blue cheese? Stilton or Gorgonzola adds that signature tang, but Gorgonzola Dolce is a milder option if you prefer less funk. Toasting the walnuts in a dry skillet for 3-4 minutes (until fragrant) transforms their flavor—don’t skip this step. Fresh thyme and rosemary from the grocery store’s produce section stay vibrant longer than dried, so grab a few sprigs extra for garnish.
No Stilton? Roquefort or Cabrales work beautifully—just adjust the amount if your cheese is extra salty. Short on walnuts? Pecans or candied pecans add sweetness that balances the blue cheese. The Dijon mustard is non-negotiable—it brightens the richness, but if you’re out, whole-grain mustard thinned with a splash of water is a decent swap. For the olive oil, Kirkland Signature or California Avocado Ranch brands add fruity notes that elevate the dish. The honey glaze is optional but adds a stunning finish—local raw honey works best if you want to splurge.
Stuffed pork tenderloin keeps best when refrigerated for up to 2 days, but it reheats beautifully—just warm in a 325°F oven with a splash of broth for 10 minutes. For make-ahead prep, stuff the tenderloin and refrigerate it (uncooked) for up to 12 hours before roasting. The blue cheese filling stays creamy if you wrap the stuffed tenderloin tightly in plastic. Leftovers? Slice thinly and serve on crostini with a drizzle of honey—game-changer for lunch. The roasting pan can go straight into the dishwasher, but the butter and honey glaze will need a quick wipe.
Why You'll Love This Recipe

Step-by-step instructions for blue cheese stuffed pork tenderloin
Here's how to create a showstopping centerpiece with creamy blue cheese and nutty crunch at its heart.
Prepare the Pork and Stuffing Mixture
Begin by trimming any excess fat from the 1.5 lb pork tenderloin, leaving about ¼ inch of fat cap for flavor and moisture. Using a sharp boning knife, make a deep vertical cut about 1 inch from one end, being careful not to cut all the way through. Open the cut like a book to create a pocket for the stuffing.
In a small bowl, combine 8 oz blue cheese crumbles, 0.5 cup toasted walnuts, 0.25 cup fresh thyme, 2 cloves minced garlic, 1 tbsp Dijon mustard, 0.125 cup chopped rosemary, 0.5 tsp freshly ground black pepper, and 1 tsp honey. Mix gently with your fingers until evenly distributed—this is the creamy, nutty surprise that will make every bite unforgettable. Gently stuff this mixture into the pocket you created in the pork, pressing lightly to help it hold its shape.
Season and Sear the Pork
Pat the pork dry with paper towels—this ensures a perfect sear. In a small bowl, mix 1 tsp Diamond Crystal kosher salt and 0.5 tsp freshly ground black pepper, then rub this generously over the entire surface of the pork, including the stuffed side. Let it sit at room temperature for 15-20 minutes while you preheat your oven to 425°F.
Heat 2 tbsp extra-virgin olive oil in a large oven-safe skillet over medium-high heat until shimmering. Place the pork in the skillet, cut-side down, and sear for 4-5 minutes until the bottom develops a deep golden-brown crust. Flip carefully and sear the other side for another 3-4 minutes. The pork should release easily from the skillet when ready—this is your cue that it's time to transfer it to the oven.
Roast to Juicy Perfection
Transfer the skillet to the preheated oven and roast for 15-18 minutes until the internal temperature reaches 145°F when measured with an instant-read thermometer. The pork should be tender but not yet fully cooked through—this ensures it finishes at the perfect doneness. Remove the pork from the oven and let it rest for 5 minutes before slicing.
While the pork rests, use a wooden spoon to scrape up any browned bits from the skillet. Add 2 tbsp softened unsalted butter and 1 tbsp red wine vinegar, then simmer for 1-2 minutes until the butter melts and the pan sauce thickens slightly. This pan sauce will elevate your pork from delicious to extraordinary.
Slice and Serve with Pan Sauce
Slice the pork into ½-inch thick medallions, being careful not to let the stuffing spill out. Arrange the slices on a warm platter, spooning the pan sauce generously over the top. The contrast of creamy blue cheese, crunchy walnuts, and tender pork will make this dish a standout for any occasion.
Serve immediately with roasted vegetables, mashed potatoes, or a crisp green salad to balance the richness. The pork should be juicy and tender with a crispy exterior, while the blue cheese stuffing adds a luxurious surprise with every bite. This recipe delivers on its promise of creamy, tender perfection every time.
Pro Tips For Making Blue Cheese Stuffed Pork Tenderloin
- SEAR FIRST, THEN STUFF: High heat for 2 minutes on each side before stuffing locks in juices—pork releases its own moisture when seared, so it won’t dry out when you cut it open later. I learned this the hard way after serving a dry, sad center once. ---
- TOAST THE WALNUTS: Dry-toast the walnuts in a separate pan until they smell nutty and golden—about 3-4 minutes on medium. This prevents them from turning to mush inside the pork and adds a deeper flavor that cuts through the blue cheese’s funk. ---
- DON’T OVERFILL THE CAVITY: Stuff the pork loosely—pack it too tight, and the cheese will leak out during cooking. A loose fill (about 2/3 of the cavity) lets the pork cook evenly without bursting. (Yes, even if it looks understuffed.) ---
- BASTE WITH OLIVE OIL: After searing, spoon extra-virgin olive oil over the pork every 5 minutes while roasting—it keeps the exterior crisp and the cheese from drying out. Skip the butter; it’ll burn before the pork finishes.
Troubleshooting great blue cheese stuffed pork tenderloin
Stuffing Won't Stay
If your blue cheese filling leaks out during cooking, try this trick: use toothpicks to secure the pocket. Insert 2-3 toothpicks through the stuffed side at a slight angle—this keeps the filling contained while allowing the pork to cook evenly. Remove them just before serving so they don't overcook. I've also had success with kitchen twine tied around the stuffed section, but toothpicks work better for single servings. 💡
Pork Too Dry
Overcooking is the #1 cause of dry pork tenderloin. Use a meat thermometer and pull the pork at 145°F internal temperature—no higher! The resting period (5-10 minutes) lets juices redistribute. For extra moisture, brush the pork with melted butter during the last 5 minutes of roasting. I swear by Plum brand for its high smoke point. 🌡️
Blue Cheese Too Salty
If your blue cheese is aggressively salty, balance it with 1 extra tbsp honey or ½ tsp maple syrup in the stuffing mixture. For mild blue cheese options, Gorgonzola Dolce or Roquefort work beautifully. If you're using pre-shredded cheese, rinse it briefly under water to remove anti-caking agents that can make it saltier. 🧀
Uneven Cooking
Pork tenderloins can cook unevenly if they're not the same thickness throughout. Trim any irregular sections to create an even surface before butterflying. For thicker cuts, reduce oven temperature to 400°F and add 5 minutes to your roasting time. I've found that All-Clad stainless steel pans distribute heat more evenly than cast iron for this dish. ⚡
Stuffing Too Soft
If your blue cheese filling becomes too soft during cooking, mix in 1 tbsp chopped fresh parsley or ¼ cup breadcrumbs to add structure. Chilling the stuffed pork for 30 minutes before cooking also helps the filling hold its shape better. For extra stability, add 1 egg white to the stuffing mixture—it binds without affecting flavor. 💪
Pan Sauce Too Thin
If your pan sauce isn't thickening properly, add 1 tsp cornstarch mixed with 1 tbsp cold water and simmer until it reaches a glossy consistency. For deeper flavor, deglaze with 2 tbsp red wine instead of vinegar. I like to finish with a pinch of smoked paprika** for a subtle BBQ touch that complements the blue cheese perfectly. 🍷

Frequently asked questions
Can I use this recipe with a smaller pork tenderloin?
Yes! For a 1 lb pork tenderloin, reduce the blue cheese to 6 oz and walnuts to 0.375 cup while keeping all other ingredients proportional. The cooking time remains similar, but check the internal temperature at 140°F since smaller cuts cook faster. This works perfectly for individual servings or appetizers.
What's the best way to reheat leftovers?
Slice leftovers into ½-inch medallions and reheat in a 325°F oven for 10-12 minutes with a splash of chicken broth to keep them moist. For quick reheating, use a skillet over medium-low heat for 2-3 minutes per side—this preserves the crispy exterior while warming through. Never microwave stuffed pork!
How can I make this dish vegetarian?
Swap the pork for a large portobello mushroom cap or firm tofu block (marinated in soy sauce and smoked paprika). Stuff with the same blue cheese-walnut mixture, then roast at 400°F for 20-25 minutes until tender. The texture contrast remains fantastic, though the cooking method differs slightly due to plant-based ingredients.
Can I prepare this ahead of time?
Stuff the pork and refrigerate (uncooked) for up to 12 hours before roasting. For make-ahead leftovers, cook and refrigerate for 2 days or freeze for 1 month. Thaw frozen pork in the fridge overnight, then reheat gently. The flavors actually improve after resting overnight—perfect for meal prep!
What's the best wine pairing?
A bold Cabernet Sauvignon or Syrah complements the blue cheese's tang and pork's richness. For white wine lovers, try an oaked Chardonnay with 12% ABV or higher. The tannins in red wines cut through the fat beautifully, while the oak in whites balances the dish's complexity. Sparkling wine also works for a refreshing contrast!
