Ingredients

• 2 large Yellow onion
• 1 medium Apple (preferably Granny Smith or Honeycrisp)
• 2 tablespoons Unsalted butter
• 1 tablespoon Olive oil
• 4 sprigs Fresh thyme
• 1 teaspoon Honey
• 0.5 teaspoon Kosher salt
• 0.25 teaspoon Black pepper
• 2 sheets Parchment paper

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Peel and thinly slice the yellow onions into half-moons.

Step 3

Core and thinly slice the apple (no need to peel unless desired).

Step 4

In a skillet over medium heat, add the butter and olive oil. Once the butter has melted, add the sliced onions and a pinch of salt.

Step 5

Cook the onions for 8-10 minutes, stirring frequently, until they start to soften and turn golden brown.

Step 6

Add the apple slices to the skillet with the onions and cook for an additional 3-5 minutes until the apples begin to soften slightly.

Step 7

Drizzle in the honey and stir to evenly coat the onions and apples. Remove from heat.

Step 8

Cut two large sheets of parchment paper (about 12x16 inches) and fold each one in half to create a crease. Open them back up flat.

Step 9

Divide the onion and apple mixture evenly between the two sheets, placing the mixture on one side of the crease for each sheet.

Step 10

Place two sprigs of fresh thyme on top of each portion. Sprinkle with a little more salt and black pepper, if desired.

Step 11

Fold the parchment paper over the mixture, then tightly crimp and fold the edges in a half-moon shape to completely seal the packets.

Step 12

Place the sealed packets on a baking sheet and bake in the preheated oven for 20-25 minutes.

Step 13

Carefully remove the packets from the oven and let them rest for 2-3 minutes before serving. Be cautious when opening as the steam will be hot.

Step 14

Serve the caramelized onions and apples directly from the parchment or transfer to a plate. Pair with crusty bread or as a side to roasted meats.
