Ingredients

Portions
2 portions
Prep time
10 minutes
Cook time
20 minutes
    300g pork tenderloin
    200g spinach
    40g butter
    3 cloves of garlic
    500g potatoes

Instructions

  1. Cut the potatoes into large chunks (quarters).
  2. Lightly spray with oil and season with salt/pepper.
  3. Place in the air fryer at 200°C for 20 minutes (or in a convection oven).
  4. Stir the potatoes every ~5 minutes to ensure even crispiness.
  5. Slice the pork tenderloin and season with salt/pepper.
  6. Put the spinach in a pot, season with salt/pepper, and sauté it quickly to evaporate almost all the water.
  7. When the water is nearly gone, add pressed garlic and a piece of butter, mix, and let the remaining water and butter form a garlic-butter emulsion.
  8. In another pan, sear the pork tenderloin quickly on both sides.
  9. Cover with a lid and turn off the heat.
  10. Serve everything on a plate.
  11. The rested tenderloin will release its juices into the pan—reduce the juices until almost none remain, then mix in the butter and drizzle the finished sauce over the meat.
  12. Enjoy! :)

Pork Tenderloin with Spinach and Air-Fryer Potatoes

Today, I have for you my favorite recipe for spinach with butter and garlic, which I decided to serve with a simple seared pork tenderloin and potatoes, baked in my new air fryer.

Spinach with Butter and Garlic

The process for making delicious spinach is very simple. Place a heap of spinach in a pot, cook out almost all the water it contains (the small amount left is strongly spinach-flavored), and then mix in a piece of butter and pressed garlic for flavor. In just 1-2 minutes, you have a fantastic side dish that pairs well with any quick-cooked meat.

I recommend using fresh spinach—I personally bought the large 400g pack from Lidl.

Fresh spinach is also sold in smaller containers, which contain younger, smaller leaves. You can use this type too, but I find it more suitable for cold dishes.

That said, this method works just as well with frozen spinach.

Pork Tenderloin and Sauce

In this recipe, I decided to sear the tenderloin quickly and then cover it with a lid, which causes it to release its juices. However, I promise you that the tenderloin will not be dry—it will melt in your mouth! :)

The most crucial step is to reduce (concentrate) the juices in the pan and then enrich them with extra butter, which you pour over the tenderloin to further enhance the flavor.

Air-Fryer Potatoes

I'm still getting familiar with the air fryer, but I've found that for potatoes, a little oil works well—mix them thoroughly and place them in the fryer at 200°C for 20 minutes (the same process works in a convection oven).

Be sure to stir the potatoes a few times so they become beautifully crispy on all sides.
