Step‑by‑Step Instructions for Stuffed Pork Tenderloin

Step 1: Prepare the Filling
In a medium skillet, heat 2 tablespoons of olive oil over medium heat. Add 3 minced garlic cloves and ½ teaspoon of red pepper flakes, sautéing for about 1 minute until fragrant. Incorporate 4 cups of fresh baby spinach, cooking until wilted (around 2-3 minutes). Drain any excess moisture, then mix in 1 cup of chopped sundried tomatoes and 1 cup of crumbled feta cheese until well combined.

Step 2: Stuff the Pork
Preheat your oven to 425°F (220°C). Butterfly a 1.5-pound pork tenderloin by slicing it lengthwise, ensuring not to cut all the way through. Open it like a book and spread the spinach and feta filling evenly across the meat. Carefully fold the tenderloin back over the filling, securing it tightly with kitchen twine to maintain its shape during cooking.

Step 3: Make the Glaze
In a small bowl, whisk together ¼ cup of balsamic vinegar, 2 tablespoons of olive oil, 1 tablespoon of Dijon mustard, 1 tablespoon of minced rosemary, the zest of 1 lemon, and a pinch of salt and pepper to taste. This glaze will infuse the roasted stuffed pork tenderloin with a tangy, rich flavor that complements the savory filling.

Step 4: Roast the Tenderloin
Place the stuffed pork tenderloin in a roasting pan and brush it generously with the balsamic glaze. Roast in the preheated oven at 425°F for 15 minutes. Then, reduce the temperature to 375°F (190°C) and continue roasting for an additional 20-30 minutes, or until the internal temperature reaches 145°F (63°C) for perfectly cooked pork, slightly pink and juicy.

Step 5: Rest and Serve
Once the pork tenderloin reaches the desired temperature, remove it from the oven and let it rest for 10 minutes. This resting period allows the juices to redistribute throughout the meat. After resting, slice the stuffed pork tenderloin into medallions to reveal the beautiful filling, and enjoy a dish that impresses both in flavor and presentation.

Make Ahead Options

Preparing this Stuffed Pork Tenderloin with Spinach and Feta in advance is a fantastic way to streamline your weeknight dinners! You can prepare the filling (spinach, sundried tomatoes, and feta) up to 3 days in advance, storing it in an airtight container in the refrigerator. Additionally, you can stuff the pork tenderloin and secure it with twine up to 24 hours prior to cooking. Just be sure to refrigerate it covered to maintain freshness. When you’re ready to cook, simply brush on the glaze and roast as instructed. This approach guarantees a flavorful, restaurant-quality dish with minimal effort on the day you’re serving it!

Expert Tips for Stuffed Pork Tenderloin

Check the Temperature: Use a meat thermometer for accuracy. Aim for 145°F for juicy, safe pork tenderloin—no guesswork!
Resting is Key: Always let the stuffed pork tenderloin rest for at least 10 minutes before slicing. This step ensures all those flavorful juices stay inside the meat.
Don’t Rush the Filling: Drain spinach thoroughly after cooking to prevent sogginess in the stuffing. Excess moisture can lead to a less-than-perfect dish.
Twine Technique: Secure with butcher’s twine for a neat appearance and to keep the filling intact. If you don’t have twine, simply fold the tenderloin over carefully.
Flavor Variations: Feel free to experiment with herbs and spices in your filling! Try adding oregano or thyme for a new spin on the classic stuffed pork tenderloin.

Storage Tips for Stuffed Pork Tenderloin

Fridge: Store leftovers in an airtight container for up to 3 days. This will keep your stuffed pork tenderloin fresh while retaining its delicious flavors.

Freezer: If you’d like to save some for later, freeze slices wrapped tightly in plastic wrap followed by aluminum foil for up to 3 months. Reheating it after freezing can bring back its savory taste.

Reheating: For the best texture, reheat your stuffed pork tenderloin in the oven at 350°F (175°C) until warmed through, about 20 minutes. This method prevents it from drying out and maintains the juicy filling.

Room Temperature: Avoid leaving the stuffed pork tenderloin out for more than 2 hours to maintain food safety. Always refrigerate the leftovers promptly.

Sweet Twist: Incorporate chopped apples or dried cranberries into the stuffing for a hint of sweetness. This unexpected blend can add a festive touch to your dinner.
Herb Infusion: Experiment with fresh herbs like thyme or oregano instead of rosemary for a different herbaceous note. Each variety opens new aromatic pathways, enhancing the overall dish.
Bacon-Wrapped: For a richness upgrade, wrap the stuffed tenderloin in crispy bacon before roasting. This will add a smoky, savory flavor that elevates the dish to new heights.
Gluten-Free: Substitute traditional breadcrumbs with gluten-free options or quinoa to keep it friendly for gluten-sensitive diners. You won’t miss out on any flavor this way!

Stuffed Pork Tenderloin with Spinach and Feta Recipe FAQs

What should I look for when selecting pork tenderloin?
Absolutely! When selecting pork tenderloin, look for a cut that is bright pink with minimal dark spots. The meat should be firm to the touch and not slimy. A tenderloin weighing around 1.5 pounds is usually ideal for stuffing.

How should I store leftover Stuffed Pork Tenderloin?
You can store any leftovers in an airtight container in the refrigerator for up to 3 days. To maintain the dish’s flavors and avoid drying out, reheating in the oven at 350°F (175°C) for about 20 minutes is recommended.

Can I freeze Stuffed Pork Tenderloin, and if so, how?
Yes, you can freeze the Stuffed Pork Tenderloin! Allow it to cool completely, then wrap it tightly in plastic wrap and again in aluminum foil to prevent freezer burn. It will stay delicious for up to 3 months. To reheat, simply thaw in the refrigerator overnight and then warm in the oven.

What if my filling turns out too watery?
Very good question! If your filling is too watery, it’s likely due to excess moisture from the spinach. After sautéing, be sure to drain the spinach thoroughly or place it in a clean kitchen towel and squeeze out the moisture before mixing it with the rest of the ingredients. This helps achieve that creamy, cohesive filling consistency.

Is this recipe suitable for my gluten-free diet?
Yes, the Stuffed Pork Tenderloin is naturally gluten-free as written! If you substitute any ingredients, like the mustard, just ensure that the alternatives are gluten-free. I often use gluten-free mustards to guarantee everyone can enjoy this delightful dish.

Can I use frozen spinach instead of fresh in my stuffing?
Definitely! If you choose to use frozen spinach, just be sure to fully thaw it and squeeze out any excess moisture before adding it to your stuffing mixture. This ensures that your filling remains flavorful and doesn’t end up too soggy.
