Ingredients for pork tenderloin recipe blackstone

Restaurant-quality pork tenderloin on your Blackstone—just eight ingredients, precise technique.

The pork tenderloin must be center-cut and uniform—ask your butcher for the straightest piece possible. Costco or Whole Foods carry excellent quality, though any reputable grocer will have suitable options. Look for even marbling and a pale pink color—avoid any pieces with grayish tones. For the dry brine, Diamond Crystal kosher salt dissolves more easily than table salt, creating a better crust. The garlic should be freshly minced—pre-minced garlic loses its punch quickly. Smoked paprika from Penzeys adds authentic depth, but any quality brand works.

No smoked paprika? Substitute with 1/2 tsp regular paprika plus 1/4 tsp liquid smoke for a similar effect. Fresh rosemary unavailable? Dried rosemary at 1/4 the amount works, though it lacks the same aromatic punch. For the basting glaze, apple cider vinegar adds brightness—substitute with balsamic vinegar if needed. The butter must be cold when added to the basting mixture to create a proper emulsion. Vegetable oil for the Blackstone should be high-smoke-point—avoid olive oil here as it can burn. If you're short on time, pre-minced garlic from a jar works, though freshly minced is ideal.

The dry-brined pork keeps covered in the fridge for up to 12 hours—this enhances tenderness dramatically. Fresh herbs like rosemary and thyme should be stored in damp paper towels in a sealed bag for 3-4 days. The basting glaze mixture can be prepped 1 day ahead and stored in the fridge. Reheat leftovers gently in a skillet with a splash of water to prevent drying. This recipe makes 4 generous servings—plan for leftovers, as the flavor improves overnight.

Step-by-step instructions for pork tenderloin Blackstone mastery

Transform your Blackstone into a crispy-skinned, juicy pork tenderloin showstopper with these precision techniques.

Preheat your Blackstone over medium-high heat for 10 minutes until it's screaming hot. While it heats, rub the pork tenderloin with 1.5 tablespoons kosher salt and 1 teaspoon freshly ground black pepper until evenly coated. Place it on a wire rack set over a baking sheet and refrigerate uncovered for 12-24 hours. This dry brine creates an impenetrable crust while keeping the interior impossibly tender.

I always use the center-cut tenderloin to avoid any connective tissue issues. The longer dry brine time gives you more control over the final texture—don't rush this step. When you're ready to cook, pat the pork dry with paper towels to remove any surface moisture that could prevent proper searing.

In a small bowl, combine 6 minced garlic cloves, 1 teaspoon smoked paprika, ½ teaspoon dried thyme, and 1 crushed sprig fresh rosemary. Rub this mixture all over the pork, pressing firmly so the spices adhere. Let it sit at room temperature for 30 minutes while your Blackstone reaches temperature.

Once the Blackstone is fully preheated, wipe it clean with a paper towel, then add 2 tablespoons vegetable oil. Spread it evenly using a paper towel, creating a thin, even layer. This oil layer prevents sticking and creates the perfect surface for that signature Blackstone crust. The high heat will cause the oil to smoke slightly—this is normal and actually enhances the flavor.

Place the pork tenderloin on the Blackstone and sear for 6-8 minutes on each side, until it develops a deep mahogany crust with caramelized edges. I press down gently on the fillet during the first minute to prevent curling and ensure even contact with the surface. The internal temperature should reach 145°F at this point—use a meat thermometer to check without opening the lid.

During the last minute of searing, add 2 tablespoons cold unsalted butter and 1 tablespoon brown sugar to the Blackstone. Tilt the pan and spoon the melted butter over the pork repeatedly. This basting technique creates a glossy, caramelized glaze that locks in moisture and adds depth of flavor. Watch carefully—the butter burns quickly at this temperature.

Remove the pork from the Blackstone and transfer it to a cutting board. In the same pan, add 1 tablespoon apple cider vinegar and scrape up any browned bits from the bottom. Let it reduce by half (30 seconds), then pour this glaze over the pork. The acidity in the vinegar cuts through the richness of the butter and adds a bright finish to the dish.

Tent the pork loosely with aluminum foil and let it rest for 10-15 minutes before slicing. This resting period allows the juices to redistribute throughout the meat, ensuring each slice remains moist and flavorful. The crust will stay intact during resting, giving you that perfect balance of crispy exterior and tender interior that makes this Blackstone pork legendary.

Using a sharp chef's knife, slice the pork tenderloin into ½-inch thick medallions against the grain. The slices should separate cleanly with minimal effort, revealing that beautiful pink center that's just shy of well-done. Arrange the slices on a warm platter and drizzle with any remaining pan juices from the Blackstone.

Serve immediately with your favorite sides—roasted vegetables, mashed potatoes, or a fresh green salad all complement this dish beautifully. The combination of crispy crust, tender meat, and that caramelized glaze makes this Blackstone pork tenderloin a showstopper that will have everyone asking for seconds.

Pro cooking tips for this recipe

Blackstone Heat Control

Your Blackstone's temperature is the single most important factor for perfect pork tenderloin. Preheat it over medium-high heat for 10-15 minutes until it's "screaming hot"—you should see a thin layer of steam when you splash a drop of water.

I use an infrared thermometer to confirm it's at 450-500°F before cooking. This high heat creates that coveted caramelized crust while keeping the interior juicy. 🔥

Dry Brine Mastery

The 12-24 hour dry brine transforms this cut from good to extraordinary. I apply 1.5 tablespoons kosher salt and 1 teaspoon black pepper directly to the pork and refrigerate it uncovered on a wire rack. This creates a dry, flavorful crust while preventing moisture loss.

Pro tip: Pat the pork completely dry before cooking—any moisture will steam instead of sear. The longer you brine (up to 24 hours), the more tender the result.

Butter Basting Technique

During the final minute of searing, add 2 tablespoons cold unsalted butter and 1 tablespoon brown sugar to the Blackstone. Tilt the pan and spoon the melted butter over the pork repeatedly—this creates a glossy, caramelized glaze that locks in moisture.

The cold butter prevents immediate burning, while the sugar adds depth. I keep a heat-resistant spatula handy to quickly scrape any butter that pools away from the pork. This step is what elevates home-cooked pork to restaurant quality.

Internal Temp Check

Use a meat thermometer to check the internal temperature—insert it into the thickest part of the tenderloin without touching bone. The pork is perfect at 145°F (160°F for well-done preference). I recommend the ThermoWorks Smoke thermometer for its accuracy and durability.

The thermometer should read 145°F after 6-8 minutes of searing on each side. Never rely on visual cues alone—pork can look done on the outside while remaining undercooked inside. ⏰

Resting Like a Pro

The 10-15 minute rest is non-negotiable for juicy results. Transfer the pork to a cutting board, tent loosely with aluminum foil, and let it rest while you finish any sides. This allows the juices to redistribute throughout the meat.

I find that resting on a wire rack over a baking sheet catches any juices that might drip, keeping them available for basting or serving. Skipping this step results in dry slices—don't be tempted to cut into it early, even if you're eager to serve.

Blackstone Maintenance

After cooking, clean your Blackstone immediately while it's still hot. Use a chainmail scrubber and Blackstone seasoning spray to remove any residue. I apply a thin layer of vegetable oil after each use to maintain the seasoning.

For extra protection, I occasionally apply a high-heat cooking spray like Mio's Seasoning Salt to prevent rust. A well-maintained Blackstone creates that perfect non-stick surface for future pork tenderloin sessions. Regular maintenance ensures your Blackstone stays ready for future cookouts. 💪
