Ingredients

• 1 lb Pork tenderloin
• 1 tsp Salt
• 0.5 tsp Black pepper
• 0.5 tsp Garlic powder
• 2 tbsp Olive oil
• 2 tbsp Unsalted butter
• 3 cups Yellow onions, thinly sliced
• 1 tbsp Brown sugar
• 1 tbsp Balsamic vinegar
• 0.25 cup Chicken broth
• 1 tsp Fresh thyme leaves (optional, for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Pat the pork tenderloin dry with paper towels and season evenly with salt, black pepper, and garlic powder.

Step 3

Heat 1 tablespoon of olive oil in a large oven-safe skillet over medium-high heat. Sear the pork tenderloin on all sides until golden brown, about 2-3 minutes per side. Remove the pork from the skillet and set aside.

Step 4

In the same skillet, add the remaining olive oil and butter. Lower the heat to medium and add the sliced onions.

Step 5

Cook the onions, stirring occasionally, until they become soft and golden brown, about 20 minutes. Sprinkle in the brown sugar and stir well to enhance caramelization.

Step 6

Deglaze the skillet by adding the balsamic vinegar and chicken broth, scraping up any browned bits from the bottom of the pan. Let this mixture simmer for 2-3 minutes until slightly reduced.

Step 7

Return the seared pork tenderloin to the skillet, nestling it into the caramelized onions. Spoon some of the onion mixture over the top of the pork.

Step 8

Transfer the skillet to the preheated oven and bake for 15-18 minutes, or until the internal temperature of the pork reaches 145°F (63°C).

Step 9

Remove the skillet from the oven and let the pork rest for 5 minutes before slicing.

Step 10

Serve the sliced pork tenderloin with the caramelized onions spooned on top. Garnish with fresh thyme leaves, if desired.
