This exceptional Mustard-Roasted Chicken recipe is lovingly adapted from the Barefoot Contessa’s Foolproof cookbook. It’s designed to bring maximum flavor with minimal effort, making it a perfect addition to your weekly meal rotation.

For those who love to plan ahead, you have the option to marinate the chicken in the delectable mustard and buttermilk mixture overnight or for a few hours. This extended soak allows the buttermilk to work its magic as a tenderizer, resulting in even juicier, more flavorful chicken. However, if time is of the essence, don’t worry! We’ve made this for guests without any marinating time at all, and they consistently rave about its incredible taste. The beauty of this recipe lies in its flexibility.

Feel free to use your preferred combination of bone-in, skin-on chicken thighs or drumsticks. While the recipe works beautifully with both, we particularly love using chicken thighs for their rich flavor and tender texture in this preparation.

Key Adaptations from the Original Recipe:

While the original recipe can be found in various places online, our version incorporates a few key changes to optimize flavor and texture:

• Fresh Breadcrumbs vs. Panko: We advocate for using fresh breadcrumbs. Unlike panko, which is lighter and flakier, fresh breadcrumbs provide a more substantial, satisfying crust that becomes wonderfully golden and crisp, absorbing the herb and garlic flavors more deeply.
• Olive Oil Blend: Instead of a mix of olive oil and butter, we use 4 tablespoons of pure olive oil for a clean flavor and excellent crisping properties.
• Buttermilk for Adhesion: We use buttermilk throughout the marinade. Its thicker consistency compared to white wine (used in some variations) ensures that the herbed breadcrumbs adhere flawlessly to the chicken, creating that perfect crust.
• Chicken Cut Selection: Our recipe specifically calls for 4 bone-in, skin-on thighs and 4 drumsticks, rather than a whole chicken cut into 8 pieces. This allows for more consistent cooking and easier handling.
• Consistent Roasting Temperature: We roast the chicken at a consistent 400ºF (200ºC) for the entire cooking duration, which helps achieve that desirable crispy exterior and thoroughly cooked interior.

Elevate Your Culinary Journey: A Whole Chicken Adventure

If you’re feeling a bit adventurous and want to maximize your culinary output, we highly recommend purchasing two whole chickens and breaking them down yourself. It’s a fantastic skill to master and offers incredible value and versatility:

1. Mustard-Roasted Delights: Use the 4 thighs and 4 drumsticks from one chicken for this incredible Mustard-Roasted Chicken recipe.
2. Tarragon Chicken Breasts: Remove the breasts from the bones of the second chicken. Reserve them for another evening to prepare our delightful Tarragon Chicken Breasts.
3. Homemade Stock: With the wings, necks, backbones, and breast bones from both chickens, you have the perfect foundation for a rich, homemade chicken stock. Simply simmer these parts gently in water with some aromatic vegetables (like onion, carrot, celery) for at least two hours. This homemade stock will elevate any soup, sauce, or rice dish you prepare.
4. Simple Chicken Salad: After simmering your stock, carefully pull any remaining meat from the stock bones. Shred this tender meat and combine it with mayonnaise, a hint of relish, and a squeeze of fresh lemon juice for a quick, delicious chicken salad.
5. Extended Stock Simmer: Return the bones to the pot and continue to gently simmer for another hour. This extracts every last bit of flavor and collagen, resulting in an even more robust and nutritious stock.

This “whole chicken adventure” not only makes the most of your ingredients but also provides multiple delicious meals and a fundamental kitchen staple (homemade stock) from a single purchase.

• 4 bone-in, skin-on chicken thighs
• 4 bone-in, skin-on chicken drumsticks
• ½ cup Dijon mustard
• ½ cup buttermilk
• 4 garlic cloves, peeled
• A small handful fresh thyme leaves (if strands are soft, no need to strip leaves)
• Zest of one large lemon
• Kosher salt and freshly ground black pepper (to taste)
• 2 cups fresh breadcrumbs (from day-old bread)
• ¼ cup olive oil

Instructions

1. Prepare the Marinade: Preheat your oven to 400ºF (200ºC) and ensure an oven rack is placed in the middle position. In a small bowl, thoroughly whisk together the Dijon mustard and buttermilk until it forms a smooth, cohesive mixture. Place the chicken pieces (thighs and drumsticks) in a large bowl. Pour the mustard-buttermilk mixture over the chicken, then toss gently to ensure every piece is evenly coated. Allow the chicken to sit in the marinade as you prepare the breadcrumbs.
2. Craft the Herbed Breadcrumbs: In a food processor fitted with a steel blade, combine the peeled garlic cloves, fresh thyme leaves (including soft stems if desired), lemon zest, 1 ½ to 2 teaspoons of kosher salt (adjust to your preference; 1.5 tsp is good for those sensitive to salt), and 1 teaspoon of freshly ground black pepper (or several large cracks from a grinder). Process these ingredients until the garlic is finely minced and the herb mixture is well integrated. Next, add the fresh breadcrumbs and the ¼ cup of olive oil to the food processor. Pulse a few times, just until the breadcrumbs are moistened and uniformly combined with the herb and oil mixture. This ensures a flavorful and slightly clumping texture that will adhere well to the chicken. Pour this prepared breadcrumb mixture into a wide, shallow bowl or onto a large plate with raised edges.
3. Coat the Chicken: Line a large baking sheet with parchment paper for easier cleanup. Take each marinated chicken piece and dip it, skin-side down only, into the seasoned breadcrumb mixture. Gently press the crumbs onto the chicken to ensure they adhere firmly and create a thick, even crust. Place the coated chicken pieces on the parchment-lined baking sheet, ensuring the crumb-side is facing upwards. As you coat more pieces, you might notice the breadcrumb mixture becoming a bit clumpy; simply use your hands to press any remaining crumbs onto the chicken pieces, ensuring no delicious crumb is left behind.
4. Bake and Rest: Bake the chicken in the preheated oven for approximately 40 minutes. The cooking time may vary slightly depending on your oven and the size of the chicken pieces. Look for a beautifully golden-brown and crispy crust, and ensure the chicken is thoroughly cooked through (internal temperature reaching 165°F / 74°C). If needed, continue baking for an additional five minutes, checking frequently to prevent over-browning. Once baked to perfection, carefully transfer the chicken from the sheet pan to a cutting board. Allow the chicken to rest for 5 to 10 minutes before cutting and serving. This crucial resting period allows the juices within the chicken to redistribute, ensuring a tender, moist, and incredibly flavorful result. Serve hot, warm, or at room temperature; this dish is delicious in any form.
