Ingredients for beachbody pork tenderloin
Lean protein, vibrant flavors, and a crisp herbed crust—this Beachbody pork delivers restaurant-quality results in one pan.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🥩 | 1 ½ lb | Center-cut, trimmed of fat |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For crust and roasting |
| Fresh Lemon Juice 🍋 | ¼ cup | From 2-3 lemons, freshly squeezed |
| Garlic Cloves 🧄 | 4 cloves | Minced for marinade |
| Fresh Rosemary 🌿 | ¼ cup | Finely chopped, stems removed |
| Fresh Thyme Leaves 🌿 | ¼ cup | From 4-5 sprigs |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | For seasoning and crust |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Almond Flour 🌰 | ½ cup | For herbed crust texture |
| Fresh Parsley Leaves 🌿 | ¼ cup | Chopped for garnish |
| Avocado Oil 🫒 | 1 tbsp | High smoke point for roasting |
| Ground Cinnamon 🌶️ | ¼ tsp | For subtle warmth |
The pork tenderloin is the star here, so center-cut and trimmed of fat is non-negotiable. Costco or Whole Foods carry premium cuts that stay tender during roasting. For the herbed crust, almond flour provides texture without heaviness, while fresh rosemary and thyme add aromatic depth. I always double-check the garlic—peeling and mincing fresh makes a noticeable difference compared to jarred minced garlic. The lemon juice should be freshly squeezed; bottled versions lack the bright acidity needed to balance the richness of the pork.
No fresh rosemary? Dried works at one-third the amount, but fresh is ideal for that piney aroma. Substitute parsley for thyme if needed, though the flavor profile shifts slightly. The almond flour can be swapped for crushed pork rinds for a meatier texture, though it won’t be as light. For the oil, avocado oil has a higher smoke point than olive oil, making it safer for roasting at 375°F. If you’re short on time, pre-minced garlic from the refrigerated section is acceptable, though freshly minced elevates the dish. The cinnamon is optional but adds a subtle warmth that pairs beautifully with the lemon and garlic.
Pork tenderloin stays fresh 3-4 days in the fridge when vacuum-sealed, but for this recipe, use it within 24 hours for optimal tenderness. Fresh herbs like rosemary and thyme should be wrapped in damp paper towels and stored in a sealed container for up to 5 days. The herbed crust mixture can be prepped ahead and refrigerated for 2 days—just let it sit at room temperature for 10 minutes before using. Leftovers reheat beautifully in a skillet with a splash of water or broth to restore moisture, making this a perfect meal prep candidate for 3-4 days of fitness-friendly lunches.

Step-by-step instructions for lemon-garlic pork tenderloin with herbed crust
This one-pan method delivers perfectly tender pork with a crispy herbed crust and bright citrus notes.
Prepare the Herb Marinade and Season the Pork
In a small bowl, combine the 0.25 cup fresh lemon juice, 4 minced garlic cloves, 0.25 cup finely chopped fresh rosemary, 0.25 cup fresh thyme leaves, 0.25 tsp ground cinnamon, 0.5 tsp ground black pepper, and 1.5 tsp Diamond Crystal kosher salt. Mix thoroughly until the herbs are evenly distributed and the salt dissolves completely. This marinade infuses the pork with aromatic depth while tenderizing the meat.
Pat the 1.5 lb pork tenderloin completely dry with paper towels—this is critical for achieving a crispy crust. Place the pork in a shallow dish and pour the marinade over it, turning to coat all sides. Let it marinate uncovered in the refrigerator for at least 30 minutes or up to 4 hours. The acidity from the lemon juice and the aromatic herbs will work together to create a flavorful exterior while keeping the interior juicy.
Create the Herbed Crust Mixture
In a separate bowl, whisk together the 0.5 cup almond flour, 1 tbsp extra-virgin olive oil, and an additional 0.5 tsp Diamond Crystal kosher salt until fully combined. The almond flour provides a nutty depth and helps create a textured crust that contrasts beautifully with the tender pork. If the mixture seems too dry, add 1 teaspoon of water to help it bind, but avoid making it too wet, as this can prevent proper adhesion to the pork.
Remove the pork from the marinade (reserve the marinade for later use) and pat it dry again with paper towels. This ensures the crust will stick properly to the meat. Spread the herbed crust mixture evenly over the surface of the pork, pressing gently to adhere. The crust should be about ¼-inch thick—thick enough to crisp but not so thick that it prevents even cooking.
Roast the Pork to Perfect Doneness
Preheat your oven to 425°F and place a wire rack on a rimmed baking sheet. Line the rack with parchment paper for easy cleanup. Place the pork tenderloin on the rack and transfer it to the preheated oven. Roast for 20 minutes to allow the crust to crisp and the pork to begin cooking through. Here's the thing—resist the urge to open the oven door during this time. Every time you peek, you risk losing heat and steam, which can lead to a less crispy crust.
After 20 minutes, carefully pour the reserved marinade over the pork. This adds an extra layer of flavor and helps keep the meat moist. Continue roasting for another 15-20 minutes, or until the internal temperature reaches 145°F when measured at the thickest part of the pork. The crust should be golden brown and crispy, while the meat should be tender and juicy. If the crust starts to brown too quickly, tent the pork loosely with aluminum foil to prevent over-browning.
Rest and Garnish for Serving
Once the pork reaches the correct internal temperature, remove it from the oven and transfer it to a cutting board. Tent it loosely with aluminum foil and let it rest for 10-15 minutes. This resting period allows the juices to redistribute throughout the meat, ensuring each slice is moist and flavorful. Skipping this step can result in dry pork, as the juices will otherwise pool on the cutting board instead of staying in the meat.
While the pork rests, finely chop the 0.25 cup fresh parsley leaves and set aside. After the resting period, slice the pork into ½-inch thick medallions. Garnish each serving with the chopped parsley and a drizzle of any pan juices that have collected on the baking sheet. The bright green parsley adds a fresh contrast to the rich, herbed crust, while the pan juices enhance the overall flavor profile. Serve immediately with roasted vegetables or a simple side salad for a well-rounded meal.
Pro Tips For Making Beachbody Pork Tenderloin
- Pat the pork dry: Pork tenderloin is lean and absorbs marinades like a sponge, but if it’s damp, your olive oil won’t stick and you’ll miss that perfect crust. Grab paper towels and press hard—this isn’t the time to go easy. (Yes, even if you’re impatient like me.)
- Use a meat thermometer: The Beachbody recipe probably says "cook until 145°F," but I learned the hard way that visual cues fail with pork tenderloin. A thermometer takes the guesswork out—stab it in the thickest part, and pull it when it hits that temp. No more dry, overcooked cuts.
- Toast the rosemary first: Fresh rosemary needs a little love before hitting the pan. Heat your olive oil in the skillet, toss in the sprigs, and let them sizzle for 30 seconds—this wakes up their flavor. Skip this, and you’re just eating a mild herb instead of aromatic magic.
- Let it rest—really: I know, you’re starving and the pork looks perfect. But cutting into it immediately means juices pooling on your plate. Tent it with foil and wait 5 minutes—this isn’t optional. The meat will stay moist, and you’ll avoid the "did I ruin dinner?" panic.
Flavor customization for this beachbody pork tenderloin
Citrus Twist Variations
Swap the lemon juice for orange juice and add ½ tsp grated orange zest to the marinade for a sweeter, tropical profile. I love this variation with 1 tsp ground coriander for warmth—it pairs perfectly with the pork’s natural sweetness. For a tangier kick, try lime juice instead, but reduce the marinating time to 20 minutes to avoid over-acidifying the meat. 🍊
Spice Level Adjustments
Add ½ tsp cayenne pepper to the marinade for a subtle heat, or increase to 1 tsp if you prefer bold spice. For a smoky depth, replace cinnamon with ½ tsp smoked paprika and add ¼ tsp chipotle powder. I’ve also used 1 tsp fresh ginger in the marinade for a zesty kick—it brightens the dish without overpowering the pork’s tenderness. 🌶️
Herb Swaps for Variety
Replace rosemary with fresh sage for an earthier flavor, or use 1 tbsp chopped mint for a refreshing twist. For a Mediterranean vibe, swap thyme for 1 tsp dried oregano and add ½ tsp garlic powder to the crust. I’ve also experimented with 1 tbsp chopped cilantro in the marinade for a bright, citrusy finish—it works surprisingly well with the lemon and garlic. 🌿
Crust Texture Options
For a nut-free crust, replace almond flour with ½ cup crushed pork rinds mixed with 1 tbsp olive oil. For extra crunch, add 2 tbsp chopped pecans or walnuts to the herbed crust. I’ve also used ½ cup panko breadcrumbs for a lighter texture—just ensure they’re lightly toasted to avoid sogginess. 🌰
Sweet-Savory Balance
Add 1 tbsp honey or maple syrup to the marinade for a caramelized finish. For a deeper sweetness, brush the pork with 1 tsp balsamic glaze after roasting. I’ve also drizzled 2 tsp tahini over the sliced pork for a nutty, creamy contrast—it’s a game-changer for flavor complexity. 🍯

Frequently asked questions
Can I use this recipe for meal prep?
This pork tenderloin keeps beautifully for 3-4 days when stored in an airtight container. Slice it after cooking, portion into containers, and pair with prepped roasted veggies or quinoa. Reheat in a skillet with a splash of water or broth to restore moisture—never microwave directly from cold. The herbed crust stays crispy when reheated quickly over medium heat.
What's the best way to check doneness?
Use a meat thermometer to check the thickest part of the pork—it should reach 145°F. The crust will be golden brown and crispy, but the internal temperature is your true guide. If you don't have a thermometer, cut into the thickest part: juices should run clear, not pink. The pork should yield slightly to gentle pressure but still feel firm.
Can I substitute almond flour in the crust?
Yes! For a nut-free option, use ½ cup crushed pork rinds mixed with 1 tbsp olive oil. For extra crunch, add 2 tbsp chopped pecans or walnuts. If you prefer a lighter texture, ½ cup panko breadcrumbs works well—just toast them lightly first to prevent sogginess. The crust will still adhere beautifully while keeping the dish fitness-friendly.
Why did my pork turn out dry?
Most likely, you skipped the 10-15 minute rest time after cooking. This crucial step lets juices redistribute. Another common mistake is overcooking—pork tenderloin cooks quickly! Remove it from the oven when it hits 145°F, not before. Also ensure your pork was center-cut and trimmed of fat—thick fat layers can insulate the meat and prevent even cooking.
How can I make this recipe spicier?
Add ½ tsp cayenne pepper to the marinade for subtle heat, or increase to 1 tsp for bold spice. For smoky depth, replace cinnamon with ½ tsp smoked paprika and add ¼ tsp chipotle powder. If you love fresh heat, try 1 tsp finely chopped jalapeño in the marinade. Always taste your marinade first—adjust to your preferred spice level before applying to the pork.
