Ingredients for ninja foodi grill pork loin
Simple marinade, smoky grill magic—just four ingredients transform basic pork into restaurant-worthy perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Loin 🍖 | 1 ½ lb | Bone-in, center-cut preferred |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For marinade and searing |
| Garlic Cloves 🧄 | 6 cloves | Minced for marinade |
| Fresh Rosemary 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Thyme 🌿 | ¼ cup | Leaves only, stems removed |
| Dried Oregano 🍃 | 1 tsp | Or 1 tbsp fresh |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | For seasoning and marinade |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Brown Sugar 🍯 | 1 tbsp | For caramelized crust |
| Apple Cider Vinegar 🍎 | 1 tbsp | For tenderizing |
| Honey 🍯 | 1 tbsp | For glaze (optional) |
| Smoked Paprika 🌶️ | ½ tsp | For smoky flavor |
| Yellow Onion 🧅 | 1 whole | Sliced for serving |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
The pork loin is the star, so center-cut bone-in is key—it stays juicier longer. I grab mine from Costco or the butcher counter at Whole Foods for that extra marbling. Look for a piece with even thickness—about 1.5 inches—so it cooks uniformly. If yours is thicker, trim it down. The Foodi's grill function works best with evenly sized cuts, so don't skip this step. For extra insurance, let the pork sit at room temperature for 30 minutes before cooking (the good stuff, not the pre-shredded kind).
No fresh rosemary? Dried works at one-third the amount, but honestly, it's not the same. The apple cider vinegar might sound weird, but it tenderizes the meat—trust me on this. Short on honey for the glaze? Maple syrup does the trick. The brown sugar isn't just for flavor—it helps create that caramelized crust we're all after. If you're feeling fancy, swap the smoked paprika for a pinch of liquid smoke (about 1/4 tsp)—it adds that campfire aroma without extra dryness. And if you've got leftover marinade, brush some on the pork during cooking for extra flavor.
This pork reheats beautifully—just pop it in a 350°F oven for 10-15 minutes with a splash of water or broth. Keeps 3-4 days in the fridge, wrapped tightly in foil. For leftovers, slice against the grain and toss with a little extra marinade to keep it moist. The Foodi's grill function leaves the pork juicy for 2-3 days if stored properly, so make extra for sandwiches. The onions and parsley can be prepped ahead and stored in the fridge for up to 5 days—just keep them dry in a sealed container.

Step-by-step instructions for Ninja Foodi grill pork loin
Transform your pork loin into a smoky, juicy masterpiece with minimal effort using the Ninja Foodi's grill function.
Prepare the Herb Marinade
In a medium bowl, whisk together the 2 tablespoons extra-virgin olive oil, 1 tablespoon apple cider vinegar, 1 tablespoon honey, 1 tablespoon brown sugar, 1 teaspoon dried oregano, 0.5 teaspoon smoked paprika, 1.5 teaspoons kosher salt, and 0.5 teaspoon ground black pepper. This marinade forms the flavor foundation that tenderizes the pork while adding depth.
Add the 6 minced garlic cloves, 0.25 cup chopped fresh rosemary, and 0.25 cup fresh thyme leaves to the mixture. Stir well to combine all ingredients thoroughly. The herbs should be finely distributed throughout the marinade for even flavor penetration.
Place the 1.5 lb pork loin in a resealable plastic bag and pour the marinade over it. Seal the bag and massage the pork gently to ensure the marinade coats all surfaces evenly. Let it marinate in the refrigerator for at least 4 hours, or preferably overnight for maximum tenderness and flavor.
Preheat the Ninja Foodi Grill
Remove the pork loin from the marinade (reserve the marinade for basting) and pat it dry with paper towels. This step is crucial for achieving that perfect crispy crust. Preheat your Ninja Foodi grill pan to 400°F using the grill function. The pan should be fully preheated before adding the meat.
While the grill preheats, slice the 1 whole yellow onion into ¼-inch thick rounds. These will caramelize beautifully alongside the pork. You can also chop the 0.25 cup fresh parsley now for garnishing later.
Here's the thing—don't rush the preheating. You'll know the grill pan is ready when it's fully smoking hot. This high heat is what creates that irresistible smoky crust on the outside while keeping the inside juicy and tender.
Sear the Pork Loin
Place the marinated pork loin directly on the preheated grill pan. Close the lid and cook for 10 minutes without disturbing it. This initial sear is critical—it develops that beautiful caramelized crust that locks in all those juices.
After 10 minutes, flip the pork loin and pour the reserved marinade evenly over the surface. This basting step adds moisture and flavor while the pork continues to cook. Return the lid and cook for another 10 minutes.
Watch for the edges to develop a deep golden-brown color—that's your visual cue that the crust is forming perfectly. The internal temperature should reach 145°F at this point. If you have a meat thermometer, check it now. If not, we'll continue cooking until we reach the perfect doneness.
Finish and Rest
Remove the pork loin from the grill pan and transfer it to a cutting board. Let it rest for 10-15 minutes before slicing. This resting period is essential—it allows the juices to redistribute throughout the meat, ensuring each slice stays moist and flavorful.
While the pork rests, place the sliced onions on the same grill pan and cook for another 5-7 minutes until they're caramelized and slightly charred around the edges. These onions will add a sweet contrast to the savory pork.
To serve, slice the pork loin into ½-inch thick medallions against the grain. Garnish each serving with the caramelized onions and a sprinkle of 0.25 cup chopped fresh parsley. The result should be a perfectly balanced dish with a smoky, crispy exterior and a juicy, tender interior.
Pro Tips For Making Ninja Foodi Grill Pork Loin
- SEAR FIRST, THEN GRILL: The Ninja Foodi’s grill function works best when you start with a hot sear—about 5 minutes on high heat with the lid off. This locks in juices before the longer cook, so don’t skip it. (Yes, even if you’re impatient like me.)
- SLICE GARLIC THINLY: Crushed or chopped garlic burns fast and turns bitter. Instead, smash each clove with the flat side of your knife, then slice into paper-thin sheets—this way, it infuses without scorching. Trust me, your pork will taste better.
- DON’T OPEN THE LID: Midway through cooking, I used to peek inside like a nervous parent. Bad idea. Every time you open that lid, you drop the internal temperature and extend cook time. Let it do its thing—you’ll know it’s done when the meat hits 145°F.
- USE A MEAT THERMOMETER: The Foodi’s built-in probe is handy, but I’ve found it can lag. Grab a cheap instant-read thermometer and stick it in the thickest part—145°F is your target. No guessing, no overcooked pork. (Your future self will thank you.)
Serving suggestions for this recipe
Classic Sides
Roasted garlic mashed potatoes are my go-to because they absorb the pork's smoky flavors beautifully. Toss 2 lbs Yukon Gold potatoes, 4 cloves roasted garlic, ¼ cup Greek yogurt, and 2 tbsp butter until creamy.
The Foodi's grill pan can even roast the potatoes while the pork rests—just toss them with oil and salt at 400°F for 20 minutes. 🥔
Fresh Contrast
A bright cucumber-avocado salad cuts through the richness perfectly. Thinly slice 1 English cucumber and 1 avocado, then toss with 2 tbsp lime juice, 1 tbsp olive oil, 2 tbsp chopped mint, and a pinch of salt.
The cool, crisp textures balance the warm pork beautifully.
Herbaceous Greens
For a lighter option, serve with arugula and pea shoots salad. Toss 4 cups mixed greens with 1 tbsp lemon vinaigrette (olive oil + lemon juice + Dijon) and top with ¼ cup toasted pine nuts. The peppery greens complement the pork's smoky notes while adding freshness. 🌿
Warm Bread Pairing
No meal is complete without crusty bread to soak up those juices. Warm a baguette in the Foodi's air fry function at 375°F for 5 minutes, then rub with garlic butter (melted butter + minced garlic + parsley). The crispy bread contrasts perfectly with the tender pork.
Sauce Elevation
Drizzle with a honey-mustard glaze (mix 2 tbsp Dijon mustard, 1 tbsp honey, and 1 tbsp apple cider vinegar) for extra depth. Brush it on the pork before serving or serve it on the side for dipping.
This adds a tangy-sweet contrast that takes the dish to the next level. 🍯
Dessert Tie-In
End the meal with a grilled peach and bourbon salad—a nod to Southern flavors. Halve 2 ripe peaches, grill them in the Foodi at 400°F for 3 minutes per side, then arrange over mixed greens with crumbled goat cheese and a drizzle of bourbon reduction**.
The caramelized peaches mirror the pork's smoky notes beautifully. 🍑

Frequently asked questions
Can I use this recipe with boneless pork loin?
Yes, but boneless pork loin cooks faster and can dry out more easily. Use a 1-inch thick cut and reduce cooking time to 8-10 minutes per side (instead of 10-10). For extra protection, wrap the pork in foil during the second 10 minutes of cooking to retain moisture.
What if my Ninja Foodi doesn't have a grill function?
No problem! Use the air fry function at 400°F instead. Place the pork on the rack and cook for 12-15 minutes per side, flipping halfway. The air fryer creates a similar crispy crust, though grill marks won't form. For extra smokiness, add ½ teaspoon liquid smoke to the marinade.
How do I fix pork that's too dry?
Overcooking is the usual culprit. For next time, use a meat thermometer and remove the pork at 140°F (it'll rise to 145°F while resting). If it's already dry, slice thinly against the grain, toss with a 1:1 mix of chicken broth and marinade, and warm through gently in a pan.
Can I make this recipe ahead of time?
Cook the pork completely (to 160°F), then let it cool in the marinade. Store in an airtight container for up to 4 days. Reheat slices in a skillet with a splash of broth for 2-3 minutes per side—they'll regain moisture and develop a fresh crust.
What's the best way to slice pork loin for perfect medallions?
Slice against the grain (at a 45-degree angle to the cutting board) for tender, ½-inch thick medallions. Use a sharp knife and cut through the grain's natural fibers. For even slices, wrap the pork in plastic wrap first—it prevents curling and makes clean cuts easier.
