Ingredients for ninja foodi grill pork loin
Pork loin that delivers restaurant-quality grill marks and juicy centers—just five ingredients make all the difference.
| Ingredient | Amount | Notes |
|---|---|---|
| Bone-In Pork Loin 🐖 | 1 ½ lb | Center-cut, 1.5-inch thick |
| Coarse Kosher Salt 🧂 | 1 tbsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | 1 tbsp | Cracked peppercorns preferred |
| Smoked Paprika 🌶️ | 1 tbsp | Spanish or Hungarian preferred |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |
| Onion Powder 🧅 | 1 tsp | From whole onions preferred |
| Mustard Powder 🌶️ | ½ tsp | For subtle depth |
| Unsalted Butter 🧈 | 2 tbsp | Cold, for basting |
| Fresh Rosemary 🌿 | ¼ cup | Finely chopped, stems removed |
| Fresh Thyme 🌿 | ⅛ cup | Leaves only, finely chopped |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For finishing grill lines |
| Apple Cider Vinegar 🍎 | 1 tbsp | For marinade brightness |
The pork loin is your star, so bone-in, center-cut is non-negotiable—it holds up better to the grill setting and gives you that perfect balance of crisp edges and tender meat. Costco or Whole Foods carry excellent cuts, but any well-marbled loin will work. Look for a piece that's roughly 1.5 inches thick—thicker cuts need longer cook times, while thinner ones risk drying out. The Ninja Foodi's grill function replicates outdoor grill marks without the flare-ups, so you don't need to worry about flare control like you would on a charcoal grill. For the dry rub, Penzeys spices are my go-to, but the grocery store stuff works just fine as long as it's fresh and aromatic.
No smoked paprika? Regular paprika plus a pinch of liquid smoke gets you close, though it won't be quite the same depth. Fresh rosemary and thyme are ideal, but dried at one-third the amount works in a pinch (just toast the dried herbs first for better flavor). The apple cider vinegar in the marinade adds brightness—substitute lemon juice if that's what you've got. For the butter basting, use European-style butter like Plugrá if you can find it; it has a higher fat content that creates better browning. If you're short on time, skip the marinade entirely—the dry rub alone still delivers amazing flavor, though the vinegar helps tenderize the meat slightly.
Pork loin holds up well for leftovers—3-4 days in the fridge, 3 months frozen. For best results, slice against the grain and reheat in the Ninja Foodi on the air fry setting for 5-7 minutes to revive the crisp edges. The dry rub keeps well in an airtight container for up to 2 weeks, so make extra for future grilling sessions. I always portion the leftovers into single servings before freezing—just pop one in the air fryer when you're ready for a quick meal. The grill marks on the Ninja Foodi's lid make it easy to create a presentation-worthy dish without any extra effort.

Step-by-step instructions for Ninja Foodi grill pork loin
Here's how to transform a simple pork loin into restaurant-worthy perfection with smoky grill marks and juicy centers.
Prepare the Pork Loin with Herbs and Spices
Start by patting the 1.5 lb bone-in pork loin completely dry with paper towels—this is crucial for achieving crispy edges. Place it on a cutting board and make shallow cuts in a crosshatch pattern on all sides using a sharp knife. This helps the seasoning penetrate deeply and prevents curling during cooking.
In a small bowl, combine 1 tbsp coarse kosher salt, 1 tbsp freshly ground black pepper, 1 tbsp smoked paprika, 1 tsp garlic powder, 1 tsp onion powder, and 0.5 tsp mustard powder. Rub this mixture generously over the pork loin, pressing it into the meat so it adheres well. In another bowl, mix 0.25 cup finely chopped fresh rosemary and 0.125 cup finely chopped fresh thyme with 1 tbsp apple cider vinegar to create a paste. Spread this herb mixture evenly over the seasoned pork loin.
Let the pork loin sit at room temperature for 30 minutes before cooking. This ensures even cooking and helps the seasoning stick. The vinegar in the herb mixture adds brightness, while the mustard powder gives a subtle depth of flavor that pairs perfectly with the smoky grill marks.
Set Up the Ninja Foodi Grill for Perfect Searing
Preheat your Ninja Foodi grill pan over medium-high heat for 5 minutes. The pan should be hot enough that when you sprinkle a few drops of water on it, they sizzle and evaporate instantly. This high heat is key to creating those coveted grill marks and crispy edges.
Once the pan is preheated, add 1 tbsp extra-virgin olive oil and swirl it around to coat the surface evenly. Place the seasoned pork loin in the pan, bone-side down. Let it sear undisturbed for 4-5 minutes until a deep golden-brown crust forms. You'll see the fat rendering out and the edges starting to crisp—that's your signal to flip.
Flip the pork loin and sear the other side for another 4-5 minutes. For extra flavor, add 2 tbsp cold unsalted butter to the pan during the last minute of searing. The butter will melt and baste the pork, adding richness and helping to create a glossy finish.
Finish Cooking to Juicy Perfection
Once both sides are beautifully seared, reduce the heat to medium and cover the Ninja Foodi grill pan with the lid. Cook the pork loin for an additional 15-20 minutes, or until the internal temperature reaches 145°F when measured with a meat thermometer. This ensures the pork is cooked to a safe temperature while remaining juicy.
To check doneness, insert the thermometer into the thickest part of the loin, avoiding the bone. The meat should feel tender and pull apart easily with a fork. If the pork loin is still slightly undercooked, continue cooking for another 2-3 minutes with the lid on. Overcooking is the enemy of juicy pork—stop as soon as it hits the target temperature.
Remove the pork loin from the grill pan and let it rest on a cutting board for 10 minutes before slicing. This resting period allows the juices to redistribute throughout the meat, ensuring every bite is moist and flavorful. Tent the pork loin loosely with foil to keep it warm during the rest.
Slice and Serve with Confidence
Using a sharp carving knife, slice the pork loin into ½-inch thick slices, cutting against the grain for maximum tenderness. The grain will be visible as lines running through the meat—angle your knife perpendicular to these lines to ensure each bite is melt-in-your-mouth delicious.
Serve the slices immediately, garnished with any remaining herb mixture or a drizzle of the rendered pan juices. The contrast of crispy edges and juicy centers, combined with the smoky, herby flavors, makes this dish a showstopper. Pair it with roasted vegetables or a fresh salad to complete the meal.
This method guarantees a perfectly cooked pork loin every time—crispy on the outside, tender and juicy on the inside, with bold flavors that come from the Ninja Foodi grill pan and the careful seasoning process.
Pro Tips For Making Ninja Foodi Grill Pork Loin
- SEAR FIRST, THEN SLOW: High heat for 3 minutes on each side—don’t skimp. That crust locks in flavor, and the Foodi’s grill function makes it easy. I used to rush this, and the pork always tasted dull.
- SALT THE NIGHT BEFORE: Pat the pork dry, then rub it with 1 tablespoon kosher salt before seasoning. Lets the salt penetrate deeper, so every bite has that balanced seasoning. (Yes, even if you’re impatient like me.)
- AVOID THE TEMP DROP: The Foodi’s grill can swing hot to cold fast. Keep the lid cracked for the last 5 minutes to stabilize the temp—prevents overcooking while the internal temp climbs.
- USE A THERMOMETER (TRUST ME): Bone-in pork loin hits 145°F, but the probe needs to go deep—past the bone, into the thickest part. I learned this the hard way after cutting into a dry slab. No guessing.
Troubleshooting your ninja foodi grill pork loin
Uneven Cooking Fix
The Ninja Foodi’s grill pan can create hot spots if your pork loin isn’t positioned properly. Place the meat bone-side down first—this helps distribute heat more evenly across the thicker side. If you notice one end browning faster, rotate the pan 90 degrees after 3 minutes of searing.
The grill’s heat circulation will then balance out, preventing overcooked edges. I’ve found this trick especially helpful when cooking thicker cuts—just keep an eye on the thermometer! 🌡️
Preventing Dry Meat
Pork loin has a tendency to dry out, especially in the Ninja Foodi’s intense grill setting. To combat this, don’t skip the butter basting—those 2 tbsp of cold butter during the last minute of searing add moisture and create a protective crust.
If your pork feels dry after cooking, try increasing the vinegar in the herb mix to 2 tbsp—it tenderizes the meat slightly. Also, resist the urge to open the lid early; the steam helps retain juices. 💧
Stuck-on Rub Solution
If your dry rub isn’t sticking to the pork loin, the meat might be too wet or the spices too coarse. Pat the loin extra dry with paper towels, then lightly oil your hands before applying the rub—this helps it adhere better.
For stubborn bits, use a pastry brush to gently press the spices into the crosshatch cuts. Pro tip: Toast your spices in a dry pan for 30 seconds before mixing to enhance their flavor and stickiness. 🌶️
Thermometer Troubles
If your meat thermometer isn’t reading accurately, try these fixes: Calibrate it first by testing in boiling water—it should read 212°F. For pork loin, insert the probe into the thickest part, avoiding the bone or fat.
If the reading jumps erratically, let the thermometer stabilize for 10 seconds before checking. I always double-check with a second thermometer if I’m unsure—better safe than sorry! 🔥
Grill Marks Fading
Want those perfect grill marks but they’re not forming? Your grill pan might not be hot enough. Preheat the Ninja Foodi on high for 7 minutes before adding oil—this ensures a scorching surface.
If marks are still faint, reduce heat to medium-high after the initial sear and let the pork sit undisturbed for 5-6 minutes per side. The key is patience; rushing will dilute the caramelization. 🔥
Leftovers Too Dry?
Reheating pork loin can turn it rubbery, but the Ninja Foodi’s air fry function saves the day. Slice leftovers and reheat at 350°F for 5-7 minutes, tossing halfway. Add 1 tsp apple cider vinegar to the air fry basket to revive moisture.
For extra crispiness, broil for 1-2 minutes at the end. This method brings back that juicy texture without drying it out. ✨

Frequently asked questions
Can I use boneless pork loin instead of bone-in?
Yes, but boneless pork loin will cook faster and may be more prone to drying out. If using boneless, reduce the cook time by 3-5 minutes and check for doneness at 140°F instead of 145°F. The bone helps regulate heat distribution, so boneless cuts need extra attention to prevent overcooking.
How do I adjust this recipe for a larger crowd?
For 6 servings, use a 2.5 lb bone-in pork loin and increase all seasonings by 50%. Cook the extra thickness by adding 5-7 minutes to the covered time. The Ninja Foodi’s grill pan can handle up to 3 lbs at once—just rotate the pan halfway if needed to ensure even cooking.
What if I don’t have a meat thermometer?
Use the finger test instead: Press your finger into the thickest part of the pork. It should feel slightly firm but still tender (like pressing your thumb into the fleshy part of your palm). For bone-in cuts, the internal temp will naturally be 5°F lower than boneless. If unsure, err on the side of undercooking—pork loin finishes cooking even after removing from heat.
Can I make this recipe ahead of time?
Cook the pork loin as directed, then let it cool completely before slicing. Store in an airtight container in the fridge for 3-4 days or freeze for 3 months. Reheat slices in the Ninja Foodi air fry at 350°F for 5 minutes—add 1 tsp apple cider vinegar to the basket to revive moisture.
Why does my pork look gray instead of pink?
Pork loin turns gray when it reaches 145°F—this is normal and safe! The pink color disappears as the myoglobin (muscle protein) changes. For extra assurance, use a thermometer to confirm the internal temp. If you prefer pink pork, aim for 135°F (medium doneness), but always ensure it rests 3 minutes after removal to let carryover cooking complete safely.
