Ingredients for beachbody pork tenderloin
Lean protein, bold herbs, and a quick marinade—everything you need for a Beachbody-approved grill masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🥩 | 1 ½ lb | Center-cut, trimmed of fat |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | Cold-pressed, fruity variety |
| Garlic Cloves 🧄 | 4 cloves | Freshly minced, aromatic |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed, bright |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Fine grain, for seasoning |
| Fresh Rosemary 🌿 | 1 tbsp | Finely chopped, fragrant |
| Fresh Thyme Leaves 🌿 | 1 tbsp | Finely chopped, aromatic |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked, coarse |
| Garlic Powder 🧄 | ½ tsp | For extra flavor depth |
| Onion Powder 🧅 | ½ tsp | For subtle sweetness |
| Ground Flaxseed 🌾 | 1 tbsp | For herb crust binding |
| Water 💧 | 3 tbsp | For flaxseed slurry |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
The pork tenderloin is your star here—center-cut and trimmed ensures maximum tenderness. Grab one from the butcher counter if you can; they'll often cut it to your exact size. Look for a piece with good marbling but minimal external fat. Costco or local farms usually have the best quality for this cut. Fresh herbs make all the difference, so skip the dried stuff (unless absolutely necessary). I always grab extra rosemary and thyme—half goes into the crust, half gets sprinkled on top right before grilling for that restaurant-quality aroma.
No fresh rosemary? Dried works at one-third the amount, but it won't have the same punch. Short on lemon juice? Lime juice or apple cider vinegar in a pinch. The flaxseed slurry is a Beachbody pro tip—it creates that perfect herb crust without adding calories. Bob's Red Mill flaxseed is my go-to, but any ground flaxseed works. For the garlic, fresh is non-negotiable here—jarred minced garlic just doesn't cut it. If you're prepping ahead, marinate the pork for up to 4 hours in the fridge, but no longer or it'll get mushy.
This herb crust keeps best when made fresh, but you can prep the slurry and dry herbs 1 day ahead. Store the mixed herbs in an airtight container in the fridge for up to 3 days. The cooked pork reheats beautifully—350°F for 10-12 minutes covered with foil, just until warmed through. For meal prep, slice against the grain and portion into containers with your favorite roasted veggies. The flavors actually improve overnight as everything melds together—trust me on this.

Step-by-step instructions for herb-crusted pork tenderloin
This herb-crusted pork tenderloin delivers melt-in-your-mouth tenderness with a crispy exterior in record time.
Prepare the Herb Flaxseed Crust
In a small bowl, combine the 1 tablespoon ground flaxseed with the 3 tablespoons water and stir vigorously. Let it sit for 5 minutes until it thickens into a gel-like consistency—this is your natural binder. While that thickens, finely chop the 1 tablespoon fresh rosemary and 1 tablespoon fresh thyme leaves (remove stems) and set aside.
In a separate bowl, mix the chopped herbs with 0.5 teaspoon garlic powder, 0.5 teaspoon onion powder, and 0.5 teaspoon ground black pepper. This herb blend is the secret to that aromatic crust that'll cling perfectly to the pork. Once your flaxseed mixture reaches a pudding-like consistency, stir in the herb blend until fully incorporated. The result should be a thick, spreadable paste ready to coat your pork.
Season and Coat the Pork
Pat the 1.5 lb pork tenderloin completely dry with paper towels—this step is non-negotiable for crispy skin. Season all sides generously with 1.5 teaspoons Diamond Crystal kosher salt and 0.5 teaspoon ground black pepper. The salt should adhere well, not just sprinkle on top.
Now for the fun part: spread the herb flaxseed mixture evenly over the entire surface of the pork, pressing gently to ensure it sticks. The crust should be about ¼-inch thick when applied. Place the coated pork on a plate and refrigerate for 15 minutes while you preheat your grill or skillet. This chilling time helps the crust adhere better and prevents it from sliding off during cooking.
Cook to Perfect Doneness
Heat 2 tablespoons extra-virgin olive oil in a large skillet over medium-high heat until shimmering. Add the pork and cook for 4-5 minutes per side, turning once, until the crust is deep golden brown and the internal temperature reaches 145°F (measured with a meat thermometer). The crust should be crispy enough to hold its shape when you lift the pork.
For the final touch, add 2 tablespoons lemon juice and 4 cloves freshly minced garlic to the pan. Spoon this fragrant mixture over the pork and let it sizzle for 30 seconds to infuse the flavors. Remove from heat and let the pork rest for 5 minutes—this resting period is crucial for redistributing juices, ensuring each slice stays tender and moist.
Serve with Fresh Garnish
Slice the pork into ½-inch thick medallions against the grain for maximum tenderness. Garnish each serving with 0.25 cup chopped fresh parsley and a squeeze of extra lemon juice if desired. The parsley adds a bright contrast to the rich herb crust, while the lemon juice brightens the dish with a citrusy finish.
Serve immediately with your favorite sides—grilled vegetables, a fresh salad, or roasted potatoes all pair beautifully. The herb crust will stay crispy for the first few bites, while the interior remains juicy and perfectly cooked. This dish proves you don't need hours in the kitchen to create restaurant-quality pork tenderloin.
Pro Tips For Making Beachbody Pork Tenderloin
- USE A MEAT THERMOMETER: I learned this the hard way—pork tenderloin can go from perfect to dry in seconds. Aim for 145°F internal temp (155°F if you prefer it extra well-done), and pull it out before it hits your target. The residual heat keeps it juicy while it rests.
- SMASH THE GARLIC: Don’t just mince it—use a flat-side of your knife or a mortar and pestle to crush those cloves into a paste. This releases more flavor into the olive oil, and the dish actually tastes brighter. (Yes, even if you’re impatient like me.)
- SALT THE PORK TWICE: First, dry the tenderloin thoroughly with paper towels, then season it generously with kosher salt right after removing it from the fridge. Let it sit for 10 minutes before cooking—this guarantees crispy skin and deep flavor penetration. (Your future self will thank you.)
- REST IT UNDER FOIL: After roasting, tent the pork with foil and let it rest for 5-10 minutes. This keeps it warm while the juices redistribute—skipping this step means a dry, sad center. (I know, I know, but trust the process.)
Serving suggestions for beachbody pork tenderloin
Herb-Crusted Protein Plate
This tenderloin pairs perfectly with roasted Brussels sprouts tossed in 1 tbsp olive oil, ½ tsp smoked paprika, and a pinch of salt—roast at 425°F for 20 minutes until crispy.
The smoky depth complements the herb crust beautifully. I always double the batch and store leftovers in airtight containers for up to 4 days. 🥦
Citrus Brightness Balance
A mango-avocado salad with lime dressing cuts through the richness while adding tropical vibrancy. Toss 2 cups mixed greens with ½ diced mango, ½ avocado, and a dressing of 2 tbsp lime juice, 1 tbsp olive oil, and ½ tsp honey.
The sweet-tangy contrast makes every bite feel fresh and energizing.
Carb Pairing Options
For a heartier meal, serve with garlic-herb roasted sweet potatoes—toss 2 medium sweet potatoes (peeled and cubed) with 1 tbsp olive oil, 1 tsp garlic powder, and ½ tsp rosemary, then roast at 400°F for 25 minutes.
The natural sweetness balances the savory pork perfectly. 🍠
Meal Prep Strategy
Slice the cooked pork into ½-inch medallions and portion with roasted veggies in glass meal prep containers for up to 4 days. Reheat at 350°F for 10 minutes to maintain moisture.
I store the herb crust separately in the fridge to keep it crispy—just sprinkle fresh parsley on top before serving. This keeps flavors vibrant for days. 💪
Protein-Packed Sides
Add quinoa pilaf with toasted almonds for extra protein—cook 1 cup quinoa in 2 cups broth, then stir in 2 tbsp chopped almonds and 1 tbsp parsley. The nutty texture contrasts the pork’s richness while adding fiber. Perfect for Beachbody meal plans! 🌾
Garnish Like a Pro
Finish each plate with a sprinkle of toasted sesame seeds and a drizzle of chili-crisp oil for a Southeast Asian twist. The nutty crunch and subtle heat elevate the dish without overpowering the herb crust. I keep these garnishes prepped in small jars on my counter for quick assembly. 🌶️
Nutrition facts
Frequently asked questions
Can I substitute chicken breast for pork tenderloin in this recipe?
While chicken breast is leaner, it won't yield the same tender, juicy results. Pork tenderloin's natural fat distribution creates melt-in-your-mouth texture that chicken can't match. If you must substitute, use boneless, skinless turkey breast instead—it has a similar texture profile when cooked properly. The herb crust will still adhere beautifully, but cooking times may vary slightly.
How do I adjust this recipe for meal prep?
Cook the pork as directed, then slice into ½-inch medallions against the grain. Store in airtight containers with parchment paper between layers for up to 4 days. Reheat at 350°F for 10-12 minutes covered with foil to maintain moisture. For extra crispiness, toast the herb crust in a skillet for 1-2 minutes before serving. The flavors actually improve overnight!
Why does my pork tenderloin turn out dry?
This usually happens from overcooking or skipping the rest time. Always use a meat thermometer—pork is safe at 145°F internal temperature. Never cut into it immediately after cooking; let it rest for 5 minutes to redistribute juices. For extra insurance, brining the pork for 30 minutes in ¼ cup salt dissolved in 4 cups water adds moisture retention without adding calories.
Can I make this recipe without fresh herbs?
Yes, but the flavor will be less vibrant. Use 1 teaspoon dried rosemary and 1 teaspoon dried thyme (not the same as fresh measurements) and add ½ teaspoon extra garlic powder to compensate. For the flaxseed crust, you'll need 1 extra tablespoon water since dried herbs don't bind as well. The crust will still work, but fresh herbs give that restaurant-quality aroma that's hard to replicate.
What's the best way to reheat leftovers?
For best results, reheat in a skillet over medium heat with 1 teaspoon olive oil for 2-3 minutes per side until warmed through. This helps restore the crispy crust. Microwave reheating works in a pinch (cover with a damp paper towel for 20 seconds), but it can make the crust soggy. For meal prep, always store the herb crust separately and add fresh parsley when reheating for maximum flavor impact.
