Ingredients for ninja foodi grill pork loin
Restaurant-quality pork loin with smoky char and juicy pink centers—just 12 ingredients and a Ninja Foodi.
| Ingredient | Amount | Notes |
|---|---|---|
| Bone-In Pork Loin 🐖 | 1 ½ lb | Center-cut, 1.5-inch thick |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For marinade and searing |
| Apple Cider Vinegar 🍎 | 2 tbsp | Balances sweetness in marinade |
| Pure Maple Syrup 🍁 | 1 tbsp | Grade B for smoky depth |
| Smoked Paprika 🌶️ | 1 tbsp | For authentic smoky flavor |
| Garlic Cloves 🧄 | 4 cloves | Minced, fresh preferred |
| Fresh Rosemary 🌿 | ¼ cup | Finely chopped, stems removed |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Yellow Onion 🧅 | ½ whole | Thinly sliced for marinade |
| Fresh Thyme Leaves 🌿 | ¼ cup | From 2 sprigs |
| Honey 🍯 | 1 tbsp | Wildflower preferred |
The bone-in pork loin is non-negotiable here—it stays juicier during the long cook. Grab the thickest cut you can find (1.5 inches minimum) from the butcher counter at Whole Foods or your local meat shop. Look for good marbling and vibrant color—pale meat means it's been sitting too long. For the marinade, apple cider vinegar cuts through the richness while the Grade B maple syrup adds that deep, smoky sweetness you'd expect from a smoker. Fresh rosemary and thyme are worth the extra trip to the market—dried just won't give you that same aromatic punch. If you're in a rush, Trader Joe's sells pre-chopped fresh herbs that work in a pinch.
No smoked paprika? Substitute 1/2 tsp liquid smoke plus 1/2 tsp regular paprika—it's not identical, but gets you close. Running low on fresh rosemary? Dried at 1/4 the amount works, though it loses some brightness. The honey here isn't just sweetness—it helps caramelize those beautiful grill marks. If you're avoiding honey, agave nectar works 1:1. For the onion, yellow or red both work, but yellow has more natural sweetness. Pro tip: Let the pork sit at room temperature for 30 minutes before grilling—this ensures even cooking and that perfect sear. And trust me on the bone-in—it's worth the extra effort for that melt-in-your-mouth texture.
Marinate the pork for at least 2 hours (overnight is even better) in the fridge. The Ninja Foodi's air crisp function means you can prep everything ahead—just store the marinade in a sealed container with the pork. Reheat the pork to 145°F internal temperature using the temperature probe for foolproof results. Leftovers keep for 3 days in the fridge, but honestly, this tastes even better the next day as the flavors meld. For meal prep, slice against the grain and portion into containers—pairs perfectly with roasted potatoes or a fresh garden salad. The smoky aroma alone will have everyone asking for seconds.

Step-by-step instructions for Ninja Foodi grill pork loin
Transform that bone-in pork loin into restaurant-quality perfection using your Ninja Foodi grill.
Create the Perfect Marinade
In a medium bowl, whisk together the 2 tablespoons extra-virgin olive oil, 2 tablespoons apple cider vinegar, 1 tablespoon pure maple syrup, 1 tablespoon smoked paprika, 1 tablespoon honey, 1.5 teaspoons kosher salt, and 0.5 teaspoon ground black pepper. This marinade is the flavor foundation—don't skip mixing it thoroughly.
Finely chop the 0.5 whole yellow onion and 0.25 cup fresh thyme leaves, then add to the marinade along with the 4 minced garlic cloves and 0.25 cup finely chopped fresh rosemary. Stir well to combine all ingredients completely. The rosemary and thyme will infuse their aromatic oils into the marinade, creating layers of flavor.
Coat and Rest the Pork Loin
Place the 1.5 lb bone-in pork loin in a shallow dish or resealable bag. Pour the marinade over the pork, ensuring it coats all surfaces completely. Use your hands to massage the marinade into the meat, especially focusing on the bone side where flavors tend to get left behind.
Cover and refrigerate for at least 4 hours (overnight is even better). This resting period allows the marinade to penetrate deeply, ensuring every bite bursts with flavor. The acidity in the apple cider vinegar will begin tenderizing the meat while the maple syrup and honey create a subtle caramelized crust during cooking.
Preheat and Prepare the Ninja Foodi Grill
Remove the pork from the refrigerator and let it sit at room temperature for 30 minutes before cooking. This helps ensure even cooking throughout. Preheat your Ninja Foodi grill to 400°F using the grill function. The high heat will create that beautiful char we're after while keeping the interior juicy.
While the grill preheats, prepare your cooking surface. For best results, I recommend using the grill rack insert that comes with your Ninja Foodi. This allows air to circulate around the pork, promoting even cooking and that coveted grill mark pattern.
Cook to Juicy Perfection
Place the marinated pork loin directly on the preheated grill rack. Close the lid and cook for 20 minutes, then flip the pork and cook another 20 minutes. You're aiming for an internal temperature of 145°F at the thickest part of the meat (use a meat thermometer for accuracy).
Here's where the magic happens: during the last 5 minutes of cooking, increase the temperature to 450°F to create a beautiful crust. You'll see the exterior develop a deep golden-brown color with visible grill marks. The pork should release easily from the rack when ready—this indicates it's developed that perfect sear.
Rest and Slice for Maximum Juiciness
Transfer the cooked pork to a cutting board and tent loosely with aluminum foil. Let it rest for at least 15 minutes before slicing. This resting period is crucial—it allows the juices to redistribute throughout the meat, preventing them from running out when you cut into it.
Slice the pork loin against the grain into ½-inch thick slices. Each piece should be tender enough to pull apart with gentle pressure, with a beautiful pink center that's just cooked through. Serve immediately with the pan juices drizzled over the top for maximum flavor impact.
Pro Tips For Making Ninja Foodi Grill Pork Loin
- SEAR BEFORE GRILLING: The Ninja Foodi’s grill function works best when you start with a hot sear—2-3 minutes per side on high heat with olive oil and smoked paprika. This locks in juices and builds flavor before the slow cook. (I used to skip this and wondered why my pork tasted more like steamed meat than grilled.)
- BRINE THE PORK LOIN: Toss the bone-in pork loin in a mix of 1 cup apple cider vinegar, 1 cup water, and 2 tablespoons maple syrup for 30 minutes before cooking. The acid tenderizes the meat and keeps it from drying out. (Yes, even if you’re impatient like me—this makes a real difference.)
- AVOID OVERCOOKING THE MAPLE: Maple syrup burns faster than you’d think, especially on the Foodi’s grill setting. Keep the heat at medium-low after searing and add the syrup in the last 5 minutes. Stir it into the juices instead of letting it pool—this prevents a bitter, burnt glaze.
- USE THE AIR CRISP FUNCTION: For that perfect crust without drying out the meat, finish with 2 minutes on the Air Crisp setting. The forced air browns the edges while the inside stays juicy. (I was skeptical until I tried it—now I never grill pork loin any other way.)
Common mistakes when making great ninja foodi grill pork loin
Overcooking the Pork
The biggest mistake I see is letting pork loin cook past 145°F internal temperature. Once it hits that mark, every extra minute in the Ninja Foodi grill dries it out. I've ruined perfectly marinated pork by walking away for just 5 minutes—don't make that mistake!
Set a timer and use the temperature probe constantly. The moment it hits 145°F, pull it out immediately. 🌡️
Skipping the Rest
You might be eager to slice into that beautiful crust, but skipping the 15-minute rest means losing all those precious juices. I've seen pork that looked perfect come out dry and stringy because it was sliced too soon.
Trust me—those juices need time to redistribute. Tent it loosely with foil while resting to keep it warm.
Uneven Marinade Application
Some people pour marinade over the pork and call it good, but that leaves the bone side flavorless. Always massage the marinade into the meat, especially around the bone. I like to use my hands for this—get into those crevices.
The bone side should be just as flavorful as the rest. If you're using a bag, squish it around to ensure even coating. 🍖
Wrong Temperature Settings
Starting at 400°F is perfect, but many people either leave it too low (resulting in pale, bland pork) or crank it too high (burning the exterior before the inside cooks).
The Ninja Foodi's precision is your friend—stick to the 400°F for most of the cook, then only boost to 450°F for that final 5 minutes of crust development.
Not Using the Grill Rack
Cooking pork loin directly on the grill surface can lead to uneven cooking and lost juices. Always use the grill rack insert that comes with your Ninja Foodi. It allows air to circulate around the meat, promoting even cooking and those beautiful grill marks.
The rack also prevents the pork from sitting in its own juices, which can make the exterior soggy. ⚡
Ignoring the Bone
Some people remove the bone before cooking, thinking it's easier. But that bone-in cut stays juicier during the long cook, and the bone actually helps distribute heat more evenly. If you're worried about the bone, just trim any excess fat or silver skin before marinating.
The bone will add depth to your flavor and keep the meat moist—don't skip it! 💪

Frequently asked questions
Can I use boneless pork loin instead of bone-in?
You can, but bone-in pork stays juicier and more flavorful during the long cook. The bone helps distribute heat evenly and adds depth to the flavor. If you prefer boneless, look for a thick cut (1.5 inches minimum) and trim excess fat before marinating. The cooking time will be slightly shorter, but you'll lose that extra moisture retention from the bone.
How do I know when the pork is fully cooked?
Use a meat thermometer to check the internal temperature at the thickest part of the loin. It should reach 145°F—this ensures juicy pink centers while keeping it safe to eat. The Ninja Foodi's temperature probe makes this easy! Pull it out immediately when it hits that mark to avoid overcooking.
Can I make this recipe without the air crisp function?
Yes, but you'll miss the beautiful crust. Use the grill function at 400°F for 35-40 minutes total, flipping halfway. For extra crispiness, broil for 2-3 minutes at the end (watch closely to avoid burning). The air crisp function gives better control, but traditional grill mode still delivers great results.
What are the best sides to serve with this pork?
Roasted potatoes with rosemary and garlic pair perfectly, as do grilled asparagus or a fresh garden salad. For a heartier meal, try creamy mashed sweet potatoes or sautéed green beans. The smoky flavor of the pork works well with slightly sweet sides that balance its richness.
How long can I store leftovers?
Store cooked pork in an airtight container in the fridge for up to 3 days. Reheat in the Ninja Foodi using the air fry function at 350°F for 5-7 minutes, or until warmed through. The flavors actually improve slightly after resting overnight! For longer storage, freeze for up to 3 months.
