Pork Tenderloin Recipe On Blackstone Griddle: Smoky Char and Juicy Slices

Mastering pork tenderloin on a Blackstone griddle delivers tender, juicy results with smoky char. The high heat creates a perfect sear while keeping the inside moist.

I developed this method after years of trial and error, learning that the key is preheating the griddle properly. A simple dry rub enhances the natural pork flavor without overpowering it.

The griddle’s even heat ensures consistent cooking, producing slices with a caramelized crust and a soft, succulent center. This technique transforms a simple cut into a restaurant-worthy main course.

Serve with seasonal vegetables or a fresh salad for a complete meal. The process is straightforward yet yields impressive results every time.

The pork tenderloin must be high-quality for optimal results. Whole Foods or butcher shops offer the best cuts—look for even marbling and a pinkish-red hue. The dry rub ingredients should be freshly opened; old spices lose potency quickly. A Blackstone griddle is ideal, but a heavy cast-iron skillet works as a backup (though heat distribution won’t be as even).

No smoked paprika? Regular paprika plus a pinch of cayenne mimics the depth. Fresh garlic can replace powder at a 3:1 ratio, but minced finely first. If red bell peppers aren’t available, green or orange work, though they’ll add a slightly different sweetness. For a more herbaceous finish, fresh sage or thyme can join the rosemary.

Store pork tenderloin in its original packaging in the coldest part of the fridge for up to 3 days, or freeze for 6 months. The dry rub keeps indefinitely in an airtight container. Fresh rosemary lasts about 1 week wrapped in damp paper towels in the fridge.

Step-by-Step Instructions for Pork Tenderloin on Blackstone Griddle

Here’s the method for achieving tender, juicy pork with smoky char on your griddle.

Step 1: Season the Pork Tenderloin

Pat the 1.5 lb Pork Tenderloin dry with paper towels to ensure an even sear. In a small bowl, combine the 1.5 tsp Kosher Salt, 1 tsp Black Pepper, 1 tsp Smoked Paprika, 1 tsp Garlic Powder, 1 tsp Onion Powder, and 0.5 tsp Dried Thyme. Rub this mixture over the pork, pressing it into the surface for maximum adhesion.

This dry brine not only seasons the meat but also helps create a beautiful crust. Let it sit at room temperature for 15-20 minutes while you prepare the griddle and vegetables. The seasoning will penetrate the surface, enhancing both flavor and texture.

Step 2: Prep Vegetables and Preheat the Griddle

Thinly slice the 1 whole Yellow Onion and slice the 1 whole Red Bell Pepper into strips. Strip the leaves from the 2 sprigs Fresh Rosemary and roughly chop them. These aromatics will complement the pork beautifully.

Preheat your Blackstone griddle over medium-high heat until it’s ripping hot—a drop of water should sizzle and evaporate immediately. This high heat is crucial for developing that sought-after char while keeping the inside juicy.

Step 3: Cook the Pork Tenderloin

Drizzle the 2 tbsp Olive Oil over the griddle and spread it evenly. Place the seasoned pork tenderloin on the griddle. Sear it for 4-5 minutes per side, until a deep brown crust forms. Add the 2 tbsp Unsalted Butter and baste the pork with it as it cooks, along with the chopped rosemary.

For even cooking, rotate the pork 90 degrees halfway through each side to create crosshatch grill marks. The internal temperature should reach 145°F for perfect doneness. Remove the pork from the griddle and let it rest under a loose foil tent for 10 minutes.

Step 4: Sauté the Vegetables

On the same griddle, add the sliced yellow onion and red bell pepper. Sauté for 5-6 minutes until they soften and develop light char marks. Stir occasionally to prevent burning, but allow some pieces to caramelize for added depth of flavor.

The residual fond from the pork will infuse the vegetables with savory richness. Once they reach your desired tenderness, transfer them to a serving platter alongside the rested pork tenderloin.

Step 5: Slice and Serve

Slice the pork tenderloin against the grain into ½-inch thick medallions. The juices should pool slightly on the cutting board, indicating perfect doneness. Arrange the slices over the sautéed vegetables on the platter.

Serve immediately while hot. The combination of smoky char from the griddle, tender pork, and caramelized vegetables creates a dish that’s both rustic and refined. Every bite should deliver juicy meat with a satisfying crust.

Classic Chimichurri

This vibrant green sauce cuts through the richness of the pork beautifully. I blend 1 cup fresh parsley, 4 garlic cloves, ¼ cup red wine vinegar, and ½ cup olive oil with a pinch of red pepper flakes. The acidity brightens each bite. 🌿

Sweet Heat Glaze

Mix ½ cup honey with 2 tbsp sriracha and 1 tbsp soy sauce for a sticky, spicy-sweet coating. Brush it on during the last 2 minutes of cooking. The heat caramelizes the glaze into a glossy finish.

Soften 4 tbsp butter and mix with 1 tbsp chopped rosemary and 1 minced garlic clove. Dollop on warm slices for a luxurious melt. This was my grandmother’s trick for special occasions. ✨
