Tools & Equipment Needed

To make French Onion Chicken Foil Packets with Cheesy Asparagus, gather the following tools:

• Large skillet
• Cutting board
• Chef’s knife
• Measuring spoons
• Baking sheet
• Heavy-duty aluminum foil
• Spatula or wooden spoon

Optional helpful tools:

• Garlic press
• Kitchen tongs

Step-by-Step Instructions

1. Caramelize the Onions

Melt 2 tablespoons unsalted butter in a large skillet over medium-high heat.

Add the thinly sliced onions and season lightly with salt and fresh cracked pepper.

Cook the onions for 5–8 minutes until softened.

Reduce the heat to medium and continue cooking, stirring occasionally, until the onions become deeply caramelized, about 15 minutes.

If the pan becomes dry during cooking, pour in 1/4 cup chicken broth to deglaze and keep the onions moist.

Stir in 3 cloves minced garlic and cook for about 1 minute, until fragrant.

Turn off the heat and allow the onions to cool slightly.

2. Preheat the Oven and Prepare Foil

Preheat the oven to 425°F (220°C).

Cut two sheets of heavy-duty aluminum foil, each measuring 14 by 12 inches (35 × 30 cm).

Lay each sheet flat on your work surface.

3. Arrange the Chicken and Asparagus

Place one chicken breast near the center of each foil sheet.

Arrange trimmed asparagus along one side of the chicken following the length of the foil.

Drizzle both the chicken and asparagus with a little olive oil.

Season with:

• 1 teaspoon garlic powder
• 1 teaspoon dried oregano
• 1 teaspoon red crushed chili pepper flakes (optional)
• Pinch of salt and fresh cracked pepper

4. Add Onions and Cheese

Spread the caramelized onion mixture evenly on top of each chicken breast.

Sprinkle shredded mozzarella cheese or Gruyère over the onions.

5. Seal the Foil Packets

Fold the foil over the chicken and vegetables.

Crimp the edges together and fold the ends upward to seal.

Do not wrap too tightly—leave a little space inside the packet so heat can circulate.

6. Bake the Foil Packets

Transfer the sealed packets to a baking sheet.

Place them in the oven with the sealed side facing upward.

Bake for 25–30 minutes, until the chicken is fully cooked through.

Cooking time may vary depending on the thickness of the chicken breasts.

7. Broil for a Golden Finish

Carefully open the foil packets.

Switch the oven to broil mode and return the packets to the oven for about 2 minutes to lightly crisp the cheese.

Remove from the oven and sprinkle with fresh chopped parsley.

Serve immediately.
