If you’re on the hunt for a meal that’s easy to make, packed with flavor, and requires minimal cleanup, this recipe for chicken baked in foil with fennel and sun-dried tomatoes is a perfect choice.
The foil packets not only seal in the savory juices of the ingredients but also create a fragrant steam that ensures every bite is tender and satisfying.
It’s a one-pot wonder in disguise, ideal for busy weeknights or casual gatherings when you want a dish that feels special but doesn’t demand hours in the kitchen.
Why Foil Packets Make This Recipe Stand Out

Foil packet cooking takes simplicity to a new level. By sealing all the ingredients together, the foil traps steam that naturally enhances the flavors of the chicken and vegetables.
This method ensures everything cooks evenly and keeps the chicken tender while preserving its juiciness.
The fennel and sun-dried tomatoes infuse the dish with a Mediterranean-inspired aroma, making it feel indulgent without being time-consuming. Plus, cleanup is a breeze—just toss the foil, and you’re done.
Tips for Prepping Your Ingredients Like a Pro
A bit of preparation goes a long way in elevating this recipe. Here are a few tips to make it even easier:
- Season in Advance: Salting the chicken before assembling the packets lets the seasoning penetrate deeper, enhancing the flavor.
- Uniform Slices: Cut the fennel, onion, and potatoes into evenly sized pieces to ensure consistent cooking.
- Refrigeration for Flavor: Letting the packets rest in the fridge before baking allows the ingredients to marinate and the flavors to meld. These small steps ensure your one-pot recipe delivers maximum flavor with minimal effort.
Modifications for Any Dietary Needs
This one-pot recipe is wonderfully adaptable to suit different dietary preferences:
- Gluten-Free: Naturally gluten-free, no changes needed!
- Low-Carb: Replace the potatoes with cauliflower florets or zucchini slices.
- Vegan Option: Swap chicken for firm tofu or tempeh, and use vegetable broth for added flavor.
- These simple swaps allow you to enjoy this recipe no matter your dietary restrictions, making it a versatile choice for family dinners or entertaining guests.
Make It a Complete Meal

While this dish is a star on its own, you can elevate it with a few complementary sides or finishing touches:
- A crisp green salad with a light vinaigrette enhances the freshness of the meal.
- Serve with crusty bread to soak up the delicious juices from the foil packets.
- Pair with a glass of white wine or sparkling water infused with citrus for a refreshing contrast. These add-ons make the meal feel even more complete, perfect for impressing guests or indulging yourself on a quiet evening.
This one-pot recipe for chicken baked in foil with fennel and sun-dried tomatoes is proof that simple techniques can lead to spectacular results. It’s a meal that delivers flavor, ease, and versatility, making it a go-to option for any occasion.

Chicken Baked in Foil with Fennel & Sun-Dried Tomatoes Made Easy
Equipment
- Aluminum foil (20 x 12-inch sheets)
- Meat thermometer
- Rimmed baking sheet
Ingredients
- 5 tablespoons extra-virgin olive oil
- 6 garlic cloves sliced thin
- 1 teaspoon minced fresh thyme
- ¼ teaspoon red pepper flakes
- 12 ounces Yukon Gold potatoes unpeeled, sliced crosswise ¼ inch thick
- 1 fennel bulb stalks discarded, bulb halved, cored, and cut into ½-inch-thick wedges, layers separated
- ½ large red onion sliced ½ inch thick, layers separated
- ¼ cup oil-packed sun-dried tomatoes rinsed, patted dry, and chopped fine
- ¼ cup pitted Kalamata olives chopped fine
- ¾ teaspoon table salt divided
- 4 6- to 8-ounce boneless, skinless chicken breasts, trimmed
- ¼ teaspoon pepper
- 2 tablespoons balsamic vinegar
- 2 tablespoons minced fresh basil
Instructions
- Spray the centers of four 20 by 12-inch sheets of aluminum foil with vegetable oil spray. Microwave olive oil, garlic, thyme, and red pepper flakes in a large bowl until garlic begins to brown (about 1 minute). Add potatoes, fennel, onion, sun-dried tomatoes, olives, and ½ teaspoon salt to the bowl. Toss to combine.
- Pound the thicker end of each chicken breast between sheets of plastic wrap to uniform ½-inch thickness. Pat chicken dry with paper towels, then sprinkle with the remaining ¼ teaspoon salt and pepper.
- Position 1 foil sheet with the long side parallel to the counter. Arrange one-quarter of the potato slices in two rows perpendicular to the edge of the foil. Top with one chicken breast and one-quarter of the vegetable mixture. Repeat with the remaining foil, potatoes, chicken, and vegetables. Drizzle any remaining oil mixture over the chicken.
- Bring the short sides of the foil together and crimp tightly to seal. Crimp the open ends of the packets, leaving headroom inside. Refrigerate for at least 1 hour or up to 24 hours.
- Adjust the oven rack to the lowest position and heat to 475°F. Place the packets on a rimmed baking sheet. Bake for 18–23 minutes, until the chicken reaches an internal temperature of 160°F. Let packets rest for 3 minutes.
- Transfer packets to individual plates. Open carefully to release steam, then slide contents onto plates. Drizzle balsamic vinegar over the chicken and vegetables and sprinkle with fresh basil.
