Ingredients for ninja foodi grill pork loin roast
Pantry staples plus fresh herbs. Simple ingredients for restaurant-quality results.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Loin Roast 🥩 | 2 ½ lb | Boneless, trimmed of excess fat |
| Olive Oil 🫒 | 2 tbsp | Extra-virgin for richness |
| Kosher Salt 🧂 | 2 tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | 1 tsp | Freshly ground for best flavor |
| Garlic Cloves 🧄 | 4 cloves | Minced for herb infusion |
| Fresh Rosemary 🌿 | 2 tbsp | Finely chopped, stems discarded |
| Fresh Thyme 🍃 | 2 tbsp | Leaves stripped from stems |
| Smoked Paprika 🌶️ | 1 tsp | For smoky depth |
| Dijon Mustard 🟡 | 1 tbsp | Whole grain preferred |
| Brown Sugar 🍚 | 1 tbsp | Light or dark variety |
| Apple Cider Vinegar 🍏 | 1 tbsp | Balances richness |
| Onion Powder 🧅 | 1 tsp | Enhances savory notes |
The pork loin should have a light pink hue and minimal marbling—Costco or Whole Foods usually carry quality cuts. Ask the butcher to trim the fat cap if you're unsure. Fresh herbs make all the difference here; grab them from the produce section with vibrant color and no wilting. The smoked paprika adds that signature char flavor—Penzeys has an excellent version if you want to splurge.
No fresh rosemary or thyme? Dried herbs at one-third the amount work in a pinch, but fresh is ideal. If you don’t have Dijon, whole-grain mustard adds great texture. Brown sugar can be swapped for honey or maple syrup (just reduce slightly to avoid burning). The apple cider vinegar can be replaced with white wine vinegar if that’s what you have.
Leftovers keep well in the fridge for 4-5 days or can be frozen for 3 months. Let the roast rest before slicing—this keeps it juicy. The herb mixture can be prepped a day ahead (store in the fridge) to save time.

Step-by-step instructions for Ninja Foodi grill pork loin roast
Here's my tested method for achieving that perfect smoky char and melt-in-your-mouth tenderness every time.
Create the Herb Marinade
In a small bowl, whisk together the 2 tbsp Olive Oil, 1 tbsp Dijon Mustard, 1 tbsp Brown Sugar, 1 tbsp Apple Cider Vinegar, 2 tsp Kosher Salt, 1 tsp Black Pepper, 1 tsp Smoked Paprika, and 1 tsp Onion Powder until fully combined. This creates a glossy paste that will cling to the pork and infuse it with flavor.
Add the minced 4 cloves Garlic Cloves, 2 tbsp Fresh Rosemary, and 2 tbsp Fresh Thyme to the bowl. I like to press the herbs slightly with the back of a spoon to release their essential oils. The mixture should be fragrant and thick enough to coat the back of a spoon.
Coat and Marinate the Pork Loin
Pat the 2.5 lb Pork Loin Roast dry with paper towels to ensure the marinade adheres properly. Place it in a shallow dish and pour the herb mixture over it, turning to coat all sides evenly. Use your hands to rub it in, making sure to get into all the nooks and crannies of the roast.
Let the pork sit at room temperature for 30 minutes while you preheat your Ninja Foodi grill. This short marination allows the flavors to begin penetrating the meat without making it mushy. Don't skip this step—it makes a noticeable difference in both flavor and texture.
Grill with Smoky Precision
Preheat your Ninja Foodi grill to 400°F using the grill function. Once hot, place the pork loin directly on the grill grates. Close the lid and grill for 15 minutes to develop a deep, smoky char on the exterior.
After 15 minutes, reduce the temperature to 325°F and continue grilling with the lid closed. The pork should reach an internal temperature of 145°F in about 45-60 minutes, depending on the thickness of your roast. I check the temperature in several spots to ensure even cooking.
Rest and Slice for Maximum Tenderness
When the pork reaches 145°F, transfer it to a cutting board and tent loosely with foil. Let it rest for 10-15 minutes before slicing. This crucial step allows the juices to redistribute throughout the meat, ensuring every slice is moist and flavorful.
Slice the pork against the grain into ½-inch thick pieces. The grain runs lengthwise through the roast, so you'll want to cut crosswise. Serve immediately while still warm—the meat should be tender enough to cut with a fork but still hold its shape beautifully on the plate.
Pro Tips For Making Ninja Foodi Grill Pork Loin Roast
- Preheat the Grill: Crank the Ninja Foodi to 400°F for at least 10 minutes before adding the pork—this guarantees a proper sear on the loin’s exterior, locking in juices.
- Score the Fat: Cut shallow slits into the fat cap of the pork loin and stuff with minced garlic cloves; it infuses flavor deep into the meat as it grills.
- Skip the Overcrowding: I learned this the hard way—leaving space between the loin and the grill walls ensures even air circulation and prevents steaming instead of roasting.
- Rest Before Slicing: Tent the pork with foil and let it rest 10 minutes after grilling; it keeps the juices from running all over your cutting board.
Dietary considerations for this recipe
Gluten-Free Friendly
This recipe is naturally gluten-free as written, making it perfect for anyone with celiac disease or gluten sensitivity. All ingredients—pork loin, fresh herbs, and spices—contain no gluten. Just double-check your Dijon mustard label, as some brands add wheat flour as a thickener. 💪
Low-Carb Option
With only 1 tbsp brown sugar in the entire recipe, each serving contains minimal carbs. To reduce further, replace the brown sugar with 1 tsp erythritol or simply omit it. The smoked paprika and apple cider vinegar still deliver plenty of flavor without the carbs.
Dairy-Free Adaptation
There are no dairy products in this recipe, so it's already dairy-free by default. The olive oil and Dijon mustard create a rich, flavorful crust without butter or cream. Perfect for lactose-intolerant guests or vegan sides.
Reduced Sodium Version
To lower sodium, cut the kosher salt to 1 tsp and use low-sodium Dijon mustard. I also recommend adding 1 tsp lemon zest to brighten flavors without extra salt. The herbs and garlic still provide plenty of taste. ✨
Allergy Considerations
This recipe is free from the top 8 allergens (milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soy) as written. However, always verify your spice blends and mustard for hidden allergens or cross-contamination warnings.
Keto-Friendly Twist
For strict keto, replace the brown sugar with 1 tsp allulose or a sugar-free maple syrup. The pork loin is naturally keto-friendly with 0g net carbs per serving. Serve with roasted low-carb veggies for a complete meal.

Frequently asked questions
Can I use a different cut of pork?
Yes, but choose lean cuts like tenderloin. Avoid fatty cuts like shoulder as they need longer cooking. Adjust cooking time based on thickness and internal temp of 145°F.
How do I know when it's done?
Use a meat thermometer and check multiple spots. The thickest part should read 145°F. The meat will continue cooking while resting, so remove it just as it reaches temp.
What if my pork loin is smaller or larger?
Adjust cooking time proportionally. For a 2 lb roast, reduce time by about 20%. For a 3 lb, increase by 20%. Always rely on internal temperature, not time alone.
Can I prepare this in advance?
Marinate the pork overnight in the fridge for deeper flavor. Let it sit at room temperature for 30 minutes before grilling. Don’t pre-cook and store, as it dries out when reheated.
