Ingredients
Scale
- 1 (1 to 1.5 pounds) pork tenderloin, trimmed
- 1 cup fresh spinach, chopped (substitute with kale or Swiss chard if you prefer)
- 1/2 cup sun-dried tomatoes, chopped (oil-packed for extra flavor or dry-packed rehydrated)
- 1/2 cup shredded mozzarella cheese (feel free to swap with feta or goat cheese for a tangy twist)
- 2 cloves garlic, minced
- 1 tablespoon olive oil, plus extra for drizzling
- 1 teaspoon dried Italian herbs (oregano, basil, thyme blend)
- Salt and freshly ground black pepper to taste
- Kitchen twine for tying (or toothpicks if you’re in a pinch)
When I first started making stuffed pork tenderloin, I stuck to simple ingredients—just like the ones my mom would toss together without a recipe. Over time, I found that these basics hit the sweet spot between fresh and flavorful. And the substitutions? They’re there because I know how life goes—sometimes you’re missing an ingredient, and that’s okay. I’ve made this with whatever was in my fridge, and it still turned out great every time.
Instructions
- Preheat your oven to 400°F (200°C). This higher temperature helps seal in the juices and gives the pork a lovely golden crust.
- Lay the trimmed pork tenderloin flat on a cutting board. Using a sharp knife, carefully slice the tenderloin lengthwise down the middle, being careful not to cut all the way through. Open it like a book and gently pound it with a meat mallet or rolling pin to an even thickness, about 1/2 inch. This step reminds me of standing on that wobbly chair next to my dad, watching him tenderize meat for big family meals—it’s all about patience and care.
- In a small bowl, mix together the chopped spinach, sun-dried tomatoes, mozzarella, minced garlic, olive oil, dried Italian herbs, salt, and pepper. This filling is what transforms the pork from simple to spectacular. I sometimes add a pinch of crushed red pepper flakes for a little kick, depending on my family’s mood.
- Spread the filling evenly over the flattened pork, leaving a small border around the edges to prevent the filling from spilling out.
- Carefully roll the pork tenderloin back up, enclosing the filling. Use kitchen twine to tie it securely in 3 to 4 places, or use toothpicks if you’re in a hurry. This step is where the magic happens—each tied bundle holds a promise of that juicy, cheesy surprise inside.
- Heat a tablespoon of olive oil in an oven-safe skillet over medium-high heat. Once hot, sear the pork on all sides until golden brown, about 2-3 minutes per side. This seals in the juices and adds a beautiful crust. I always remind myself not to skip this step, even when I’m rushing—it really makes a difference.
- Transfer the skillet to the preheated oven and roast the pork for 20-25 minutes, or until the internal temperature reaches 145°F (63°C). Use a meat thermometer if you have one—it’s the best way to avoid overcooking.
- Remove from the oven, tent with foil, and let it rest for 5-10 minutes before slicing. Resting is key. I learned this the hard way when my first attempt turned out dry because I sliced too soon. Letting it rest redistributes the juices and keeps every bite tender.
- Slice into 1-inch pieces and serve immediately.
