The pork tenderloin quality is paramount. Optimal results require USDA Choice or Prime—look for consistent color and minimal marbling. Whole Foods or Costco offer reliable selections. The fresh herbs must be vibrant—avoid wilted or yellowing leaves. For the Dijon, Grey Poupon provides consistent acidity and depth. Trim the silver skin yourself for even cooking (most butchers will do this on request).
No fresh rosemary? Dried at one-third the amount works, but fresh delivers superior aroma. Thyme can be substituted with marjoram in a pinch. Short on Dijon? Whole-grain mustard adds texture but maintain the quantity. Brown sugar can be swapped for honey (though not strictly vegan), but adjust to taste as honey is sweeter. The balsamic vinegar can be apple cider vinegar if needed.
The herb mixture can be prepped 1 day ahead and refrigerated. Cooked pork keeps for 3-4 days in the fridge or freezes well for 3 months. Always bring pork to room temperature before grilling—this ensures even cooking and maximum tenderness.

Step-by-Step Instructions for Ninja Grill Pork Tenderloin
This method delivers tender results with minimal effort and maximum flavor.
Step 1: Prepare the Herb Crust
In a small bowl, combine the 2 tbsp Dijon Mustard, 2 tbsp Olive Oil, 2 tbsp Fresh Rosemary, 2 tbsp Fresh Thyme, 4 cloves Garlic Cloves, 1.5 tsp Kosher Salt, 1 tsp Black Pepper, 1 tsp Paprika, 1 tbsp Brown Sugar, 1 tbsp Balsamic Vinegar, and 1 tsp Lemon Zest.
Mix until the ingredients form a cohesive paste. The herbs should be evenly distributed throughout the mixture, and the sugar should begin to dissolve into the liquids. This paste will create a flavorful crust that locks in juices and adds depth to every bite.
Step 2: Coat the Pork Tenderloin
Pat the 1.5 lb Pork Tenderloin dry with paper towels to ensure the crust adheres properly. Place the tenderloin on a clean work surface and spread the herb paste evenly over all sides, pressing gently to ensure full coverage.
Let the coated tenderloin sit at room temperature for 10-15 minutes while you preheat your Ninja Grill. This short rest allows the flavors to penetrate the meat slightly, enhancing the overall taste.
Step 3: Grill to Perfection
Preheat your Ninja Grill to 400°F using the grill function. Once hot, place the coated pork tenderloin directly on the grill grates. Close the lid and cook for 15-18 minutes, flipping halfway through the cooking time.
The tenderloin is done when the internal temperature reaches 145°F in the thickest part. Look for a golden-brown crust that forms a slight crust—this is your visual cue that the herb mixture has caramelized beautifully.
Step 4: Rest and Slice
Transfer the pork tenderloin to a cutting board and let it rest for 5-10 minutes. This resting period allows the juices to redistribute throughout the meat, ensuring each slice is moist and tender.
Slice the tenderloin into ½-inch thick medallions and serve immediately. The meat should be slightly pink in the center, juicy, and infused with the aromatic flavors of the herb crust.
Pro Tips For Making Ninja Grill Pork Tenderloin
- Preheat the Grill: I learned this the hard way—crank the Ninja grill to 400°F for at least 10 minutes before adding the pork, or you’ll get uneven searing and lukewarm crust.
- Pound the Tenderloin: Sounds weird, but it works: flatten the pork slightly with a rolling pin so it cooks evenly and absorbs the Dijon-herb rub better.
- Rest Before Slicing: After pulling it at 145°F, tent the pork with foil for 8-10 minutes—this keeps the juices from pooling on the cutting board instead of in the meat.
- Use Fresh Herbs: Dried rosemary and thyme won’t cut it here; their fresh versions bruise nicely into the mustard rub and actually change the outcome.
Creative Variations of This Recipe
Asian Glazed Twist
Swap the herb crust for a 3 tbsp soy sauce, 2 tbsp honey, 1 tbsp grated ginger glaze. I brush it on during the last 5 minutes of grilling. The Ninja’s high heat caramelizes the glaze beautifully. 🔥
Spicy Coffee Rub
Combine 2 tbsp ground coffee, 1 tbsp chili powder, and 1 tbsp brown sugar for a bold crust. The coffee enhances the pork’s natural richness—trust me, it’s my competition secret. I learned this trick at a local BBQ competition.
Mediterranean Style
Use 2 tbsp chopped kalamata olives, 1 tbsp capers, and 1 tsp oregano in your crust mix. Add ½ cup crumbled feta after grilling. This reminds me of my coastal rides through Mediterranean towns.
Apple Cider Brined
Brine the pork in 2 cups apple cider, ¼ cup salt, and 2 tbsp maple syrup for 4 hours before grilling. The cider’s acidity tenderizes while adding subtle sweetness. I forage wild herbs to add to the brine sometimes.
Balsamic Fig Glaze
Simmer ½ cup balsamic vinegar with 4 chopped dried figs until syrupy. Brush on during grilling. This pairs wonderfully with the pork’s natural sweetness and creates a glossy finish. 🍷

Frequently Asked Questions
Can I use a different cut of pork?
Pork loin works but needs 5-7 minutes more cooking time. Avoid pork shoulder—it’s too fatty for this method. Stick to lean cuts for best results.
How do I know when it’s done without a thermometer?
Press the thickest part—it should feel firm but still springy, like a tennis ball. The crust will be golden brown and juices run clear.
What if my herb crust burns?
Lower the grill temp to 375°F and tent with foil. The sugar in the crust can caramelize quickly, so keep an eye on it.
Can I make this ahead of time?
Prepare the crust mix 1 day ahead. Grill the pork just before serving—it’s best hot off the grill.
