Ingredients for pork tenderloin recipe blackstone
Lean pork, bold seasonings, and Blackstone magic—this is your shortcut to restaurant-worthy crispy bark.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🥩 | 1 ½ lb | Center-cut for even cooking |
| Kosher Salt 🧂 | 1 ½ tbsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | 1 tsp | Cracked peppercorns for texture |
| Garlic Powder 🧄 | 1 tbsp | Freshly toasted preferred |
| Smoked Paprika 🌶️ | 1 tsp | For subtle smokiness |
| Avocado Oil 🫒 | 2 tbsp | High smoke point for searing |
| Fresh Rosemary 🌿 | ¼ cup | Finely chopped, stems removed |
| Fresh Thyme Leaves 🌿 | ¼ cup | Or 1 tbsp dried thyme |
| Apple Cider Vinegar 🍎 | 1 tbsp | For tenderizing marinade |
| Honey 🍯 | 1 tbsp | Local preferred for flavor |
| Mustard Powder 🌶️ | ½ tsp | Adds depth to seasoning |
| Vegetable Oil 🫒 | 1 tbsp | For Blackstone preheating |
| Fresh Parsley 🌿 | ⅛ cup | Chopped for garnish |
The pork tenderloin is non-negotiable here—center-cut ensures even cooking, while the 1.5 lb size feeds four with perfect proportions. Costco or Whole Foods carry the best quality, but any butcher will trim it for you. Look for uniform thickness (about 1.5 inches) to avoid overcooking. The avocado oil is worth the splurge for its high smoke point—Trader Joe's has a great affordable option. Fresh herbs? Local farmers markets have the most vibrant rosemary and thyme, but grocery store bunches work if you use them within 3 days.
No fresh rosemary? Dried at half the amount works in a pinch, but trust me—fresh makes all the difference. The honey in the marinade isn't just for sweetness; it helps create that caramelized bark when seared. Short on time? Pre-marinate for 1-2 hours (overnight is ideal). The apple cider vinegar tenderizes beautifully, but if you're avoiding acidity, swap for extra honey. For the Blackstone prep, vegetable oil is your best friend—it spreads evenly and won't burn at high heat. And if you're wondering about the mustard powder? It's a game-changer for depth, but Dijon mustard at 1 tsp works too.
Marinated pork keeps 2 days in the fridge, covered tightly. The Blackstone? Preheat it for 10 minutes on high before cooking—this ensures that perfect sear. Leftovers reheat best in a 350°F oven for 10 minutes with a splash of water to keep them juicy. I always make a double batch because the second night is even better—crispier bark, more flavorful. Store cooked pork wrapped in foil for 3 days or freeze for 3 months. Garnish with parsley right before serving—it brightens up the dish and adds that restaurant touch.

Step-by-step instructions for perfect Blackstone pork tenderloin
This method delivers restaurant-quality crust and juicy centers every time.
Prepare the Pork with Herb Marinade
In a mixing bowl, combine the 1.5 tbsp kosher salt, 1 tbsp garlic powder, 1 tsp smoked paprika, 0.5 tsp mustard powder, 0.25 cup finely chopped fresh rosemary, and 0.25 cup fresh thyme leaves. Mix until the herbs are evenly distributed and the spices cling to the dry ingredients. This blend creates the perfect balance of herby brightness and smoky warmth that will penetrate the meat.
Place the 1.5 lb pork tenderloin on a plate and rub the herb mixture all over, pressing it into the surface so it adheres well. In a separate small bowl, whisk together the 1 tbsp apple cider vinegar and 1 tbsp honey to create a tenderizing glaze. Brush this mixture generously over the seasoned pork, coating it completely. Let the pork sit at room temperature for 30 minutes before cooking—this ensures even cooking and maximum flavor penetration.
Preheat the Blackstone and Sear the Pork
Preheat your Blackstone grill over medium-high heat for 10 minutes until it's scorchingly hot. Add the 1 tbsp vegetable oil and spread it evenly across the surface using a paper towel. The oil should shimmer slightly—this indicates it's ready for searing. Place the pork tenderloin on the Blackstone and let it sear undisturbed for 4-5 minutes on one side until it develops a deep golden-brown crust.
Flip the pork and repeat on the opposite side for another 4-5 minutes. Here's the thing—don't press down on the meat with a spatula. I've learned the hard way that this squishes out the juices and leaves you with dry pork. Instead, let the natural weight of the tenderloin create that perfect crust. You'll know it's ready when the exterior is deep golden brown and the edges start to pull away slightly from the Blackstone.
Cook to Juicy Perfection
Reduce the heat to medium and continue cooking the pork for an additional 8-10 minutes, turning occasionally to ensure even browning. The internal temperature should reach 145°F when measured with a meat thermometer inserted into the thickest part of the pork. This is the magic number for juicy, tender pork that's still slightly pink in the center—what we call "medium" for pork tenderloin.
As the pork cooks, you'll notice the herb crust developing a beautiful caramelized bark. This is your visual cue that the flavors are intensifying. If the crust starts to burn before the pork reaches temperature, simply move it to a cooler spot on the Blackstone. The goal is that perfect balance of crispy exterior and tender interior.
Rest and Serve with Herby Garnish
Transfer the cooked pork to a cutting board and let it rest for 5-10 minutes before slicing. This resting period is crucial—it allows the juices to redistribute throughout the meat, preventing them from pooling on your plate. While it rests, heat the remaining 2 tbsp avocado oil in a small pan over low heat until just warm.
Slice the pork tenderloin into ½-inch thick medallions and arrange on a serving platter. Drizzle with the warmed avocado oil and sprinkle generously with the 0.125 cup chopped fresh parsley. The parsley not only adds a pop of color but also brightens the dish with its fresh, slightly peppery notes. Serve immediately with your favorite sides—roasted vegetables, mashed potatoes, or a crisp green salad all pair beautifully with this Blackstone masterpiece.
Pro Tips For Making Pork Tenderloin Recipe Blackstone
- Crank Heat to 450°F First: I learned this the hard way—starting at 375°F means your pork will steam instead of sear. Hit max heat for 3-4 minutes to get that deep crust on the Blackstone, then drop to 375°F to finish. The first 90 seconds are when flavor happens.
- Pat Dry Like It’s Your Job: Wet pork sticks to the Blackstone like glue, and that’s a one-way ticket to soggy meat. Use paper towels to dry it thoroughly—even the crevices—before seasoning. I skip this when I’m lazy, and the difference in texture is noticeable.
- Don’t Crowd the Pan: Two tenderloins? Cook them one at a time. Stacking them or overloading the Blackstone steals heat and leaves you with unevenly cooked, pale pork. Give each piece space to breathe—your future self will thank you.
- Rest Under Foil: After pulling it off the Blackstone, tent the pork with foil and let it sit for 5-10 minutes. This keeps it from drying out while you slice, and the juices redistribute so every bite stays moist. I know, I know, but trust the process—cutting into it too soon is a rookie move.
Storing and reheating this recipe
Refrigerator Storage
After cooking, let your Blackstone pork tenderloin cool to room temperature for 30 minutes before storing. Place it in an airtight container with a paper towel pressed against the slices to absorb excess moisture.
Store in the fridge for up to 3 days—the flavors actually deepen overnight. I always slice it first to make reheating easier later. 🌡️
Freezer Prep Tips
For long-term storage, wrap each slice individually in plastic wrap before placing them in a freezer-safe bag. This prevents freezer burn and keeps the medallions separate for easy reheating. Label with the date and freeze for up to 3 months.
Thaw overnight in the fridge before reheating. I like to portion into individual servings to avoid thawing more than needed.
Oven Reheating Method
For the best texture, reheat sliced pork in a 350°F oven for 10-12 minutes on a wire rack set over a baking sheet. This allows heat to circulate evenly and prevents sogginess.
Add 1 tbsp water or broth to the pan to maintain moisture. Cover loosely with foil during the first 5 minutes to help retain juices. 🔥
Stovetop Refresh
For quick reheating, use a skillet over medium heat with 1 tbsp avocado oil. Add slices and cook for 2-3 minutes per side until heated through. Keep the heat medium-low to avoid drying out the pork. I find this method works best for smaller portions—perfect for busy weeknights.
Microwave Shortcut
When you're in a hurry, use the microwave on 50% power for 1-1.5 minutes per serving, covered with a damp paper towel. Check the internal temperature—it should reach 165°F.
Add 1 tsp water or broth to the plate before microwaving to prevent drying. This method works best for single servings rather than the whole cut.
Reviving Crispy Bark
To restore that coveted crispy exterior, broil the reheated slices for 1-2 minutes** on high, watching closely to avoid burning. Brush with a tiny bit of melted butter or avocado oil before broiling.
This quick step makes reheated pork feel fresh again—perfect for serving to guests who might not know it was reheated. ✨

Frequently asked questions
Can I use a regular grill instead of a Blackstone?
Yes! While a Blackstone's flat surface gives perfect even cooking, you can adapt this recipe for any grill. Use medium-high heat and a grill grate to create those crispy sear marks. Just monitor the heat more closely—charcoal grills may require adjusting vents to maintain consistent temperatures. The key is patience and a good meat thermometer to hit 145°F.
How do I prevent the pork from drying out?
Lean pork tenderloin dries out fast if overcooked! The secret is timing and resting. Use a meat thermometer to pull it at 145°F (medium), and never skip the 5-10 minute rest before slicing. Also, avoid pressing down on the meat while cooking—this squeezes out juices. A quick marinade with honey and vinegar helps too!
What's the best way to slice the pork?
Slice against the grain at a 45-degree angle for maximum tenderness. Use a sharp knife and cut into ½-inch thick medallions. For even slices, freeze the pork for 20 minutes first—this firms up the fat for cleaner cuts. Always slice after resting to lock in juices!
Can I make this ahead of time?
Cook the pork fully, then refrigerate for up to 3 days or freeze for 3 months. The flavors actually improve overnight. For serving, reheat in a 350°F oven for 10 minutes with a splash of water to keep it moist. Pro tip: Reheat slices individually for crispy bark every time!
What sides pair best with Blackstone pork tenderloin?
This dish shines with hearty sides that complement its herby crust. Try creamy garlic mashed potatoes, roasted Brussels sprouts with bacon, or a bright citrus salad. For a crowd-pleaser, serve with apple slices and a honey-mustard dip—they cut through the richness perfectly!
