Ingredients
- 1.5 lbs Pork tenderloin
- 8 slices Applewood-smoked bacon
- 2 medium, thinly sliced Yellow onions
- 2 tbsp Butter
- 1 tbsp Olive oil
- 2, minced Garlic cloves
- 1 tbsp Dijon mustard
- 1/2 tsp Kosher salt
- 1/4 tsp Black pepper
- 1 tsp Dried thyme
Instructions
- Step 1: Preheat oven to 400°F (200°C). Season pork tenderloin with 1/2 tsp salt and 1/4 tsp black pepper. Wrap each bacon slice around the tenderloin, securing with toothpicks if needed. Place in a roasting pan and roast for 25-30 minutes until internal temperature reaches 145°F (63°C) and bacon is crisp.
- Step 2: While pork roasts, melt 2 tbsp butter and 1 tbsp olive oil in a skillet over medium heat. Add 2 thinly sliced yellow onions and cook, stirring occasionally, for 15-20 minutes until deeply golden and caramelized. Add 2 minced garlic cloves and cook for 1 minute until fragrant. Stir in 1 tbsp Dijon mustard and 1 tsp dried thyme.
- Step 3: Remove pork from oven and let rest for 10 minutes before slicing. Slice into 1/2-inch thick pieces and arrange on plates with caramelized onions. Serve with pan drippings.
