The smoked paprika is non-negotiable—Penzeys or Spicewalla if you want to splurge, but even the grocery store stuff works if it’s fresh. I test every batch with Diamond Crystal kosher salt because it clings better to meat. For the herbs, rub the dried thyme and rosemary between your fingers before mixing to wake up those oils. Bulk bins are great for keeping everything potent.
No smoked paprika? Regular paprika plus a pinch of liquid smoke gets you close. Brown sugar can be swapped for coconut sugar or turbino if you’re avoiding refined sugar. The cayenne is flexible—skip it for mild heat or double it if you like fire. Cumin adds depth, but if you’re out, a dash of coriander works in a pinch. Always taste before applying.
Store in an airtight container away from light—stays fresh for about 6 months. I keep a small jar in the pantry and a backup in the freezer for long-term storage. Makes enough for 3-4 pork tenderloins depending on size. Just multiply if you’re feeding a crowd.

Step-by-Step Instructions for Pork Tenderloin Grill Rub
This method ensures your rub delivers maximum flavor and creates that perfect char on the grill.
Step 1: Prepare the Dried Herbs and Spices
Begin by measuring out all your spices. I always start with the dried thyme and dried rosemary, rubbing them between my fingers directly over the mixing bowl. This releases their essential oils and intensifies their aroma.
The 1 tsp Dried Thyme and 1 tsp Dried Rosemary should be crushed just before adding—this makes a noticeable difference in flavor potency. For the ground cumin, I toast the 1 tsp Ground Cumin in a dry pan for 30 seconds until fragrant to deepen its earthy notes.
Step 2: Combine the Base Spices
In a medium bowl, add the 2 tbsp Smoked Paprika, 1 tbsp Coarse Kosher Salt, and 1 tbsp Ground Black Pepper. The smoked paprika is your flavor foundation, so I use the full 2 tablespoons for that signature smokiness.
Add the 1 tbsp Garlic Powder and 1 tbsp Onion Powder next. These provide the savory depth that complements the pork beautifully. Stir these together first—they form the aromatic base that will make your rub irresistible.
Step 3: Incorporate Sweet and Spicy Elements
Now add the 2 tbsp Brown Sugar to balance the savory notes. I prefer light brown sugar for its milder molasses flavor, but dark works too. The 2 tablespoons creates just the right caramelized crust on the grill.
For heat, include the 0.5 tsp Cayenne Pepper. This amount adds warmth without overpowering—adjust if you prefer more or less heat. Mix everything thoroughly until the brown sugar is fully distributed and the rub looks uniform in color and texture.
Step 4: Store and Apply for Maximum Flavor
Transfer the rub to an airtight container. I like to make this in batches—it keeps well for up to 3 months in a cool, dark place. The flavors actually meld and improve over the first 24 hours.
When ready to use, pat your pork tenderloin dry and apply the rub generously to all sides, pressing it in firmly so it adheres. Let it sit for at least 30 minutes before grilling, or up to 24 hours in the refrigerator for deeper flavor penetration.
Pro Tips For Making Pork Tenderloin Grill Rub
- Pat It Dry: I learned this the hard way—moisture on the pork washes away the rub. Blot the tenderloin with paper towels before applying the spice mix so the smoked paprika and salt actually stick.
- Rest the Rub: After coating the meat, let it sit for 15-20 minutes. The coarse kosher salt and garlic powder need time to penetrate beyond the surface.
- Skip the Overcrowding: Resist the urge to grill all pieces at once. Give each tenderloin space on the grate so the heat circulates and the crust forms evenly.
- Toast the Spices: Sounds weird, but it works: lightly toast the smoked paprika and onion powder in a dry pan for 30 seconds before mixing. It wakes up the flavors in the rub.
Troubleshooting Great pork tenderloin grill rub
Rub Not Sticking
If your rub won’t adhere, pat the pork tenderloin completely dry with paper towels first. Any moisture creates a barrier. I also lightly brush with olive oil before applying—this helps the blend cling better to the meat’s surface.
Uneven Flavor Distribution
Always mix your rub thoroughly before applying. The brown sugar can settle at the bottom. I sift the final blend through my fingers as I sprinkle it, ensuring even coverage. Press the rub into the meat firmly with your hands.
Too Salty Taste
If your rub tastes overly salty, you may have used table salt instead of kosher salt. They measure differently by volume. Diamond Crystal kosher salt is my go-to—it dissolves evenly and has a cleaner flavor. 🧂
Burning on Grill
The brown sugar can burn at high temperatures. Keep your grill at medium heat (around 350°F). If using charcoal, bank the coals to one side for indirect cooking. I also avoid direct flame contact until the final sear.
Lacking Smoky Flavor
If your rub lacks depth, your smoked paprika may be old. Spices lose potency after 6 months. I buy from Penzeys or Spicewalla for freshness. For extra smokiness, add ½ tsp chipotle powder to the mix.
Clumping in Storage
To prevent clumping, store your rub in an airtight container with a silica packet. I keep mine in a cool, dark pantry. If clumps form, break them up with a fork before using. 💡
