  • 2 tablespoons cream cheese (optional, for extra creaminess)

How to Make It

  1. Prep the oven and pan: Heat your oven to 400°F (200°C). Line a baking sheet with foil or parchment for easy cleanup, or use an oven-safe skillet.
  2. Butterfly the pork: Place the tenderloin on a cutting board.

    Using a sharp knife, slice lengthwise down the center, stopping about 1/2 inch before cutting all the way through. Open it like a book. If needed, cover with plastic wrap and gently pound to an even 1/2-inch thickness.

  3. Season the pork: Pat dry.

    Sprinkle both sides with salt and pepper. Brush lightly with olive oil.

  4. Cook the spinach: Heat 1 tablespoon olive oil in a skillet over medium heat. Add garlic and cook 30 seconds until fragrant.

    Add spinach and cook until wilted (or warm through if using thawed spinach). Squeeze out excess liquid. Let cool slightly.

  5. Make the filling: In a bowl, combine spinach, feta, cream cheese (if using), lemon zest, parsley, oregano, red pepper flakes, 1/2 teaspoon salt, and 1/4 teaspoon black pepper.

    Taste and adjust seasoning.

  6. Fill and roll: Spread the filling evenly over the butterflied pork, leaving a small border all around. Roll the pork up tightly from the long side. Secure with kitchen twine every 1.5 to 2 inches, or use toothpicks along the seam.
  7. Sear for color (optional but recommended): Heat a slick of oil in an oven-safe skillet over medium-high.

    Sear the pork 1–2 minutes per side until lightly browned.

  8. Roast: Transfer the skillet to the oven (or place the pork on the prepared baking sheet). Roast for 18–25 minutes, until the thickest part reads 140–145°F (60–63°C) on an instant-read thermometer.
  9. Rest and slice: Transfer to a cutting board and rest 5–10 minutes. Remove twine or toothpicks.

    Slice into 1/2- to 3/4-inch rounds. Serve with lemon wedges if you like.

Keeping It Fresh

  • Storage: Refrigerate leftovers in an airtight container for up to 3 days. Keep slices in a single layer, or separate with parchment to avoid sticking.
  • Reheating: Warm gently in a 300°F (150°C) oven, covered, for 10–12 minutes, or microwave in short bursts at 50% power to avoid drying.
  • Freezing: Freeze cooked slices (well-wrapped) for up to 2 months.

    Thaw overnight in the fridge and reheat gently.

  • Make-ahead: You can assemble the stuffed tenderloin up to 24 hours ahead. Wrap tightly and refrigerate. Sear and roast just before serving.

Why This is Good for You

  • Lean protein: Pork tenderloin is a lean cut, offering plenty of protein with less saturated fat than many other cuts.
  • Greens in every bite: Spinach adds iron, vitamin K, and fiber.

    It also brings moisture, so you’re less likely to overcook the meat.

  • Flavor boosters, not fillers: Feta and lemon give bold taste without heavy sauces. A little cheese goes a long way.
  • Balanced plate: Pair with roasted vegetables or a light salad, and you’ve got a well-rounded meal that’s satisfying and nutrient-dense.

Common Mistakes to Avoid

  • Overfilling: Too much filling will squeeze out during cooking. Keep an even, thin layer and leave a border.
  • Skipping the rest: Cutting right away releases juices.

    Resting helps keep the slices moist and tender.

  • Overcooking: Pork tenderloin can dry out fast. Use a thermometer and pull at 140–145°F; it will rise a few degrees as it rests.
  • Not squeezing spinach: Excess moisture can make the filling watery and the roll slippery. Squeeze cooked spinach well.
  • Loose roll or weak ties: Secure the roll every couple of inches so it holds its shape as it cooks.

Variations You Can Try

  • Mediterranean twist: Add chopped sun-dried tomatoes and a few sliced olives to the filling.
  • Mushroom-spinach: Sauté chopped mushrooms with the garlic, then mix with the spinach before stuffing.
  • Herb-forward: Swap oregano for dill and mint, and finish with a squeeze of lemon juice over the slices.
  • Cheese swap: Use goat cheese or ricotta instead of feta for a milder, creamier filling.
  • Grill option: Sear the stuffed tenderloin over medium heat, then move to indirect heat and cover until it reaches temperature.

    Watch for flare-ups and turn occasionally.

FAQ

Can I use pork loin instead of tenderloin?

Yes, but it will take longer to cook and may need more filling. Pound it to an even thickness, roll tightly, and roast until it reaches 145°F in the center. Start checking around 35–45 minutes.

What sides go well with this?

Roasted potatoes, garlicky green beans, a lemony arugula salad, or couscous are all great.

A yogurt-cucumber sauce or simple pan juices work nicely on the side.

How do I keep the filling from leaking out?

Don’t overfill, leave a small border, and roll tightly. Secure with twine every 1.5 to 2 inches. Searing helps set the exterior, which also reduces leaks.

Is it okay if the pork is slightly pink?

Yes.

Pork is safe to eat at 145°F with a brief rest, and it may show a slight blush in the center. That’s normal and helps keep it juicy.

Can I make this dairy-free?

Absolutely. Skip the feta and cream cheese.

Replace with a dairy-free cheese or use a mix of finely chopped olives, roasted peppers, and toasted pine nuts for richness and texture.

What if I only have frozen spinach?

It works perfectly. Thaw fully and squeeze out as much liquid as possible. Measure after draining so you keep the filling balanced.

Wrapping Up

Spinach and feta stuffed pork tenderloin is the kind of dish that feels special without being complicated.

With a bright, savory filling and a juicy roast, it’s a reliable go-to for both weeknights and gatherings. Keep your roll tight, watch the temperature, and let it rest. Slice, serve, and enjoy how effortlessly impressive it is.
