Ingredients

• 1 lb pork tenderloin
• 4 tbsp unsalted butter
• 2 tbsp olive oil
• 2 large yellow onions
• 3 garlic cloves
• 3 fresh thyme sprigs
• 1 tsp salt
• 0.5 tsp black pepper
• 0.5 cup chicken stock
• 1 tbsp balsamic vinegar

Directions

Step 1

Remove the pork tenderloin from the refrigerator 20 minutes before cooking to bring it to room temperature.

Step 2

Season the pork tenderloin generously with salt and black pepper on all sides.

Step 3

Slice the yellow onions into thin rings and mince the garlic.

Step 4

Heat 2 tablespoons of unsalted butter and 2 tablespoons of olive oil in a large skillet over medium-high heat.

Step 5

Once the butter starts to foam, add the pork tenderloin to the skillet and sear it for 3-4 minutes on each side until it is golden brown all over. Remove the pork from the skillet and set it aside on a plate.

Step 6

Reduce the heat to medium and add the remaining 2 tablespoons of butter to the same skillet.

Step 7

Add the sliced onions and a pinch of salt to the pan. Cook the onions, stirring frequently, for about 10 minutes until they become soft and golden brown.

Step 8

Stir in the minced garlic and cook for 1 minute, being careful not to burn it.

Step 9

Add the fresh thyme sprigs, chicken stock, and balsamic vinegar to the onions. Stir to combine and bring to a gentle simmer.

Step 10

Return the seared pork tenderloin to the skillet, nestling it into the onion mixture.

Step 11

Cover the skillet with a lid and let the pork cook for about 12-15 minutes, or until it reaches an internal temperature of 145°F (63°C). Turn the pork once halfway through cooking to ensure even heat distribution.

Step 12

Once cooked, remove the pork tenderloin from the skillet and let it rest for 5 minutes before slicing.

Step 13

Slice the pork into 1-inch medallions and serve it alongside the caramelized onions. Spoon some of the pan juices over the top for added flavor.
