I 🍊🌿 Citrus Mojo Pork Tenderloin with Watermelon Cucumber Salad
When the temperature outside feels like an oven, dinner needs to work a little differently.
This is not the time for heavy sauces, long cooking projects, or meals that leave you feeling ready for a nap.
During a Phoenix summer, the best dinners are usually the ones that bring plenty of flavor without feeling heavy.
They are bright.
Fresh.
Easy to prepare.
And ideally, they give us a good excuse to cook outside instead of heating up the kitchen.
That is exactly what inspired this Citrus Mojo Pork Tenderloin with Watermelon Cucumber Salad.
Pork tenderloin is lean, quick-cooking, and surprisingly easy to prepare. For this recipe, it is marinated with orange, lime, garlic, cilantro, and oregano before being grilled until juicy and lightly charred.
Then comes the part that really makes the meal feel like summer: a cold watermelon and cucumber salad with fresh herbs, lime, and just enough red onion to balance the sweetness.
The pork is savory and citrusy.
The salad is crisp, juicy, and refreshing.
Together, they create a dinner that feels elevated enough for company but realistic enough to make on a weeknight.
It is proof that healthy summer cooking does not need to mean another plain grilled chicken breast or basic green salad.
Sometimes, it just needs a little citrus, a hot grill, and a very cold watermelon.

¼ teaspoon sea salt

Charred corn
Jasmine rice or cauliflower rice
Easy Step-by-Step Instructions
Step 1: Make the Mojo Marinade
In a bowl or large resealable container, combine:
Avocado or olive oil
Orange zest and juice
Lime zest and juice
Garlic
Cilantro
Oregano
Cumin
Salt
Black pepper, if using
Whisk until combined.
Add the pork tenderloin and turn it several times to coat it thoroughly.
For the best flavor, cover and marinate in the refrigerator for 30 minutes to 4 hours. Even 15 minutes will help when you are short on time.
Avoid marinating it overnight because the citrus can begin to affect the pork’s texture.
Step 2: Prepare the Watermelon Salad
While the pork marinates, add the watermelon, cucumber, red onion, and herbs to a large bowl.
Drizzle with lime juice and olive oil, then sprinkle with sea salt.
Gently toss everything together.
Refrigerate the salad while the pork cooks so it stays cold and refreshing.
Helpful tip: If your red onion tastes especially strong, soak the slices in cold water for 10 minutes. Drain and pat them dry before adding them to the salad.
Step 3: Preheat the Grill
Preheat an outdoor grill or grill pan to medium-high heat.
Remove the pork from the marinade and allow the excess liquid to drip away. Discard the used marinade.
Lightly oil the grill grates if needed.
Step 4: Grill the Pork
Place the pork tenderloin on the hot grill.
Cook for approximately 16–20 minutes, rotating it every 4–5 minutes so that it browns evenly on all sides.
The exact cooking time will depend on the thickness of the tenderloin.
Remove it from the grill when the thickest portion reaches an internal temperature of 145°F.
Step 5: Let It Rest
Transfer the pork to a cutting board and let it rest for 8–10 minutes before slicing.
Do not skip this step. Resting gives the juices time to settle back into the meat, keeping each slice tender and moist.
Slice the pork into medallions just before serving.
Step 6: Plate and Finish
Arrange the sliced mojo pork on a platter or individual plates.
Serve it alongside a generous portion of the chilled watermelon cucumber salad.
Finish with extra cilantro, lime wedges, or sliced avocado.
For a heartier dinner, add charred corn, jasmine rice, or cauliflower rice.
No-Grill Cooking Option
No outdoor grill? No problem.
Heat an oven-safe skillet over medium-high heat with a small amount of avocado oil.
Sear the pork for 2–3 minutes per side, turning until browned all over.
Transfer the skillet to a 400°F oven and roast for approximately 12–16 minutes, or until the center reaches 145°F.
Rest for 8–10 minutes before slicing.
Easy Ways to Customize It
Keep It Mild
Leave out the crushed pepper and jalapeño. The citrus, garlic, and herbs still provide plenty of flavor.
Add Some Heat
Mix thinly sliced jalapeño into the watermelon salad or finish the pork with crushed red pepper.
Add More Vegetables
Serve it with grilled zucchini, bell peppers, asparagus, or corn.
Make It AIP-Friendly
Omit the cumin and black pepper. Use extra oregano, garlic, cilantro, and citrus to maintain plenty of flavor.
Meal Prep Tips
The pork can be marinated earlier in the day and grilled when you are ready to eat.
Cooked pork will keep in an airtight container in the refrigerator for up to four days.
The watermelon salad is best during the first one or two days because the fruit releases liquid as it sits.
For meal prep, store the pork and salad separately. Reheat the pork gently, then add the cold salad immediately before serving.
Leftover pork also works beautifully in lettuce wraps, rice bowls, or chopped salads.
Why This Recipe Works for Summer
Watermelon and cucumber both bring the cold, crisp texture we crave during the hottest part of the year.
Orange and lime brighten the pork without relying on a heavy sauce.
Grilling adds smoky flavor while keeping most of the heat outside.
Most importantly, the meal is satisfying without feeling overly rich.
It gives you protein, fresh produce, healthy fats, and big flavor in a dinner that still feels appropriate when the temperature refuses to drop below triple digits.
Final Thoughts
Summer cooking should not feel like a battle against the weather.
It should be simple, colorful, and built around food that genuinely sounds good when it is hot outside.
This Citrus Mojo Pork Tenderloin with Watermelon Cucumber Salad delivers that balance.
The pork is juicy, garlicky, and full of bright citrus flavor.
The salad is cold, sweet, crisp, and refreshing.
And the whole meal feels a little more exciting than the standard weeknight routine without requiring complicated ingredients or hours in the kitchen.
Fire up the grill, chill the watermelon, and give this one a try before summer slips away.
Happy Cooking!!!
