Recipe Details

This Keto Stuffed Pork Tenderloin with Spinach and Feta recipe holds a special place in the hearts of those who crave a touch of Mediterranean flair in their keto journey. The inspiration for this dish comes from the classic flavors of the region, where spinach and feta cheese are staple ingredients, celebrated for their versatility and taste.

The pork tenderloin is an excellent choice for keto dieters due to its lean profile and high protein content. When paired with healthy fats from the olive oil and feta cheese, it creates a balanced meal that supports ketosis. The spinach not only adds color and texture but also provides a wealth of vitamins and minerals, including iron and magnesium, which are crucial for overall health.

Each ingredient has been carefully selected to ensure that you’re not only indulging in a meal that’s bursting with flavor but also one that fits within the macronutrient requirements of a ketogenic diet. The low carb count is achieved by focusing on nutrient-dense, non-starchy vegetables and using seasonings that are free from added sugars and fillers.

Preparation of Keto Stuffed Pork Tenderloin

The Method

Creating the perfect Keto Stuffed Pork Tenderloin with Spinach and Feta starts with preheating your oven to the right temperature. This ensures that once your pork hits the heat, it will cook evenly and develop a beautiful crust. When butterflying the tenderloin, patience and a steady hand are key. You want to create enough space for the filling without compromising the structure of the meat.

As you sauté the spinach, be mindful not to overcook it. The goal is to just wilt the leaves, preserving their vibrant color and nutrients. Combining the spinach with feta while it’s still warm helps the cheese soften slightly, creating a smoother filling that’s easier to spread.

When rolling the tenderloin, make sure to do it tightly to prevent the filling from spilling out during cooking. Searing the meat on all sides is crucial for locking in juices and flavor. Don’t rush this step; a golden-brown crust not only adds texture but also layers of taste. Lastly, allowing the pork to rest after roasting is not optional—it’s a must for a juicy, tender result.

Keto Stuffed Pork Tenderloin Ready to Serve


Herb-Infused Pork Tenderloin: For those who love a burst of herbal flavors, consider adding fresh rosemary or thyme to the spinach and feta mixture. The herbs will infuse the pork with aromatic flavors that complement the creamy filling.

Sundried Tomato and Olive Twist: Introduce a tangy kick by incorporating chopped sundried tomatoes and Kalamata olives into the filling. This variation adds a touch of Mediterranean zest while still keeping the dish keto-friendly.

Spicy Pork Tenderloin: If you enjoy a bit of heat, add more red pepper flakes to the seasoning or include a diced jalapeño in the spinach and feta mixture. The spice will elevate the dish, giving it an extra kick that spice lovers will appreciate.


Goat Cheese for Feta: If feta cheese isn’t to your liking or you simply want to try something different, goat cheese is a fantastic alternative. It offers a similar tangy profile and creamy texture that blends seamlessly with the spinach.

Swiss Chard for Spinach: Swiss chard can replace spinach for a slightly different flavor and texture. It’s just as low in carbs and provides a similar nutritional profile, making it an excellent option for those looking to mix up their greens.

Chicken Breast for Pork: For a lighter option, chicken breast can be used in place of pork tenderloin. It’s still keto-friendly and provides a different taste experience. Just be sure to adjust cooking times accordingly, as chicken may cook faster than pork.
