Ingredients

2-3 lb. Pork tenderloin
½ teaspoon Dried thyme

Instructions

Melt the butter in a saucepan over medium low heat, then add the onions.
3 Tablespoons Butter, 1 medium Onion
Saute the onions very slowly, stirring frequently, until completely softened and well caramelized. Remove the onions from the heat to let cool. While cooling, preheat the oven to 400°F.
Place the tenderloin on a cutting board and slice in half lengthwise, making sure not to cut all the way through- you want it to be able to close like a hotdog bun. Drizzle all sides with oil.
2-3 lb. Pork tenderloin, 8 oz. Brie cheese, 2 Tablespoons Olive oil
In a small bowl, mix the garlic powder, onion powder, paprika, thyme, salt and pepper, and rosemary.
½ teaspoon Dried thyme, ½ teaspoon Garlic powder, ½ teaspoon Onion powder, ½ teaspoon Paprika, ¼ teaspoon Dried rosemary, Salt and pepper
Place the pork in a large bowl, then sprinkle with the seasoning mixture and turn until well coated.
Slice the brie into long stripes, removing the rind if desired. Move the pork to a baking dish, flip it open, and stuff it with layers of caramelized onions and brie strips.
Close, securing the edge with toothpicks if desired, and bake for 30-40 minutes.
Let cool 10 minutes, slice, and serve!

Notes

Caramelizing onions properly is a time-intensive procedure! For a perfect caramelized onion, you'll need to stir the onions over low heat for about an hour, adding a small amount of sugar if desired. For faster onions, cook on a higher heat for less time.
I've found the perfect brie for this recipe is fromage d'affinois, which can be found at many specialty food stores. However, any mild or earthy brie will work well!
For extra deliciousness, you can add whatever you want to the stuffing. I've found that sauteed mushrooms pair beautifully. Or, add some fresh blanched spinach!
In a pinch, this recipe can also be made with any mild melting cheese. I've made it with mozzarella and swiss, and it's still delicious.
