Ingredients for beachbody pork tenderloin
Precision-cut lean protein meets citrus-herb science for restaurant-quality results in record time.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🍖 | 1 ½ lb | Trimmed of excess fat, cut into even pieces |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | High-quality, fruity variety for searing |
| Fresh Lemon Juice 🍋 | 3 tbsp | From 1 medium lemon, freshly squeezed |
| Fresh Garlic Cloves 🧄 | 4 cloves | Minced for marinade, skin removed |
| Fresh Rosemary 🌿 | 1 tbsp | Finely chopped, fresh preferred |
| Fresh Thyme Leaves 🌿 | 1 tbsp | Finely chopped, stems removed |
| Diamond Crystal Kosher Salt 🧂 | 1 tsp | For seasoning, not iodized |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked for optimal flavor |
| Honey 🍯 | 1 tbsp | Raw or local for natural sweetness |
| Red Wine Vinegar 🍷 | 1 tbsp | For acid balance in marinade |
| Fresh Parsley 🌿 | 2 tbsp | Chopped, for garnish and flavor |
The pork tenderloin is the star here—look for uniform pieces with minimal fat trim for optimal lean protein. Whole Foods or Trader Joe's carry pre-trimmed cuts, but if buying whole, trim any visible fat yourself. Freshness matters: the meat should have a vibrant pink hue and firm texture. For meal prep, purchase 1.5 lbs to yield four equal 4-ounce portions—ideal for post-workout recovery. The citrus-herb marinade works magic on the lean cut, preventing dryness while adding bright, clean flavors that complement high-performance nutrition goals.
No fresh rosemary? Dried works at one-third the amount, but fresh delivers superior aroma. Substitute thyme with oregano at equal measure if needed. For the honey, maple syrup is a 1:1 swap, though honey's floral notes enhance the marinade's complexity. The red wine vinegar can be replaced with apple cider vinegar for a milder tang. When prepping, marinate the pork for no longer than 30 minutes—citrus can over-tenderize lean cuts. For extra insurance against dryness, brine the pork for 15 minutes in ice water with 1 tsp salt before marinating (drain well before proceeding).
Marinated pork keeps 2 days in the fridge, sealed in an airtight container with marinade. For longer storage, freeze portions for up to 3 months—thaw overnight in the fridge before cooking. The marinade itself can be stored 5 days in the fridge, though it's best used fresh. When reheating, use low heat to prevent drying—165°F internal temperature ensures safety while preserving tenderness. Garnish with fresh parsley just before serving to maintain vibrant presentation, as wilting occurs quickly once chopped.

Step-by-step instructions for perfectly cooked pork tenderloin
This method delivers juicy, flavorful pork every time—no guesswork, just precision.
Prepare the Herb Marinade
In a small bowl, combine the 3 tablespoons fresh lemon juice, 1 tablespoon honey, 1 tablespoon red wine vinegar, 1 tablespoon finely chopped fresh rosemary, 1 tablespoon finely chopped fresh thyme leaves, 1 teaspoon Diamond Crystal kosher salt, and ½ teaspoon freshly ground black pepper. Whisk until fully integrated and the herbs are evenly distributed throughout the liquid.
The acidity from the lemon juice and vinegar will tenderize the pork, while the honey adds a subtle sweetness that balances the herbs. Let this marinade sit for 5 minutes to allow the flavors to meld—this brief infusion makes all the difference in the final dish.
Marinate the Pork Tenderloin
Place the 1.5 lb pork tenderloin in a shallow dish or resealable plastic bag. Pour the prepared marinade over the meat, ensuring it coats all sides evenly. If using a bag, seal it tightly and massage the marinade into the pork to guarantee full coverage. Let it marinate for 10-15 minutes at room temperature—this ensures even cooking and enhances the flavor penetration.
I always marinate at room temperature rather than refrigerated to maximize flavor absorption without overcooking. The pork should feel slightly sticky from the marinade when you handle it, indicating it's ready for cooking.
Sear the Pork for Maximum Flavor
Heat 2 tablespoons extra-virgin olive oil in a large skillet over medium-high heat until shimmering. Remove the pork from the marinade, letting any excess drip off, and add it to the skillet. Sear for 3-4 minutes per side until the exterior develops a deep golden-brown crust—this is your signal that the meat is properly sealed and ready for the final cook.
Don't overcrowd the pan; searing requires space for the meat to develop that flavorful crust. If the pork releases easily from the pan, it's ready to flip. The aroma at this stage should be irresistible—herbs, garlic, and citrus working together.
Finish Cooking to Perfect Doneness
Transfer the seared pork to a baking dish and preheat your oven to 400°F. Roast the pork for 12-15 minutes until the internal temperature reaches 145°F when measured with a meat thermometer. The pork should be tender and juicy, with no pink remaining in the center.
Here's the thing—pork tenderloin cooks quickly, so keep an eye on it after the 12-minute mark. Overcooking leads to dryness, so trust the thermometer over time. The exterior should be beautifully caramelized, while the interior remains succulent.
Rest and Garnish for Presentation
Remove the pork from the oven and transfer it to a cutting board. Let it rest for 5-7 minutes before slicing—this allows the juices to redistribute, ensuring each bite is moist and flavorful. While it rests, stir the 4 minced fresh garlic cloves into the reserved marinade and heat it gently in a small saucepan over low heat for 1 minute.
Slice the pork into ½-inch thick medallions and drizzle with the garlic-infused marinade. Garnish with the 2 tablespoons chopped fresh parsley for a pop of color and freshness. Serve immediately with roasted vegetables or a crisp green salad for a complete meal.
Pro Tips For Making Beachbody Pork Tenderloin
- USE A MEAT THERMOMETER: I learned this the hard way—pork tenderloin looks done when it’s still overcooked. Aim for 145°F internal temp; pull it off heat just as it hits that mark. The residual heat finishes cooking while keeping it juicy.
- SMASH THE GARLIC: Skip the minced garlic cloves—smash them flat with the side of your knife first. This releases more flavor and blends better into the olive oil and lemon marinade. (Yes, it looks messy, but it works.)
- SEAR IN BATCHES: Crowding the pan drops the temperature and steams the meat instead of searing. Cook half the pork first, then move it to a plate before adding the second batch. Your kitchen might smell like heaven, but the crust will be worth it.
- LET IT REST: I know, you’re hungry now, but give that pork a solid 5-10 minutes under foil before slicing. Skipping this step means juices pooling on your plate instead of in the meat. (Your future self will thank you.)

Frequently asked questions
Can I use this recipe for meal prep?
This recipe is perfect for meal prep—just cook the pork tenderloin and store it in an airtight container for up to 2 days in the fridge or 3 months in the freezer. Reheat gently to 165°F in a skillet or microwave to maintain tenderness. The marinade's acidity helps preserve freshness while keeping flavors vibrant.
What if I don't have fresh rosemary or thyme?
No problem! Use dried rosemary (1 teaspoon) or dried thyme (1 teaspoon) instead, but reduce the amount by one-third. For thyme, you can also substitute with oregano (1 tablespoon) for a similar earthy flavor. The key is maintaining the herb-to-liquid balance in the marinade.
How do I prevent the pork from drying out?
Never skip the resting time (5-7 minutes) after cooking—this lets juices redistribute. Also, avoid overcooking: use a meat thermometer and stop at 145°F internal temperature. For extra insurance, brine the pork for 15 minutes before marinating (1 tsp salt in ice water). The searing step is crucial too—it creates a flavorful crust that locks in moisture.
Can I grill this pork instead of pan-searing?
Yes! Grilling works beautifully—just marinate the pork as directed, then grill over medium-high heat for 4-5 minutes per side until the internal temperature reaches 145°F. The high heat creates those delicious grill marks while keeping the meat juicy. For extra flavor, brush with olive oil before grilling.
What are the best sides to serve with this?
This lean protein pairs perfectly with roasted Brussels sprouts, quinoa, or a mixed greens salad with balsamic dressing. For a complete meal, try asparagus with lemon or cauliflower rice. The citrus notes in the pork complement bright, fresh vegetables beautifully.
