How to Make Whole Roast Chicken With Potatoes and Leeks

  1. Prep the Base: Start by placing the leeks, garlic, olive oil, and white wine in a large cast-iron skillet or braiser. Layer lemon slices on top, which will infuse zest and moisture as the chicken roasts.

  2. Add the Chicken: Gently place the whole chicken on the bed of lemon slices. Trussing is optional, but if you want a perfectly shaped chicken, asking your butcher for assistance is a great choice.

  3. Create the Mustard Sauce: In a bowl, mix together the whole grain mustard, olive oil, apple cider vinegar, brown sugar, and minced garlic. Rub this flavorful sauce generously all over the chicken, ensuring every part is coated.

  4. Nestle the Potatoes: Surround the chicken with new potatoes, lightly dressed with olive oil and a sprinkle of salt. This will add a wonderful texture and absorb all the delicious flavors.

  5. Roast the Chicken: Preheat your oven to 375°F. Roast the chicken for about 1.5 hours, but begin checking in 20 minutes before the expected end time. The internal temperature should reach 165°F to ensure it’s perfectly cooked.

  6. Rest Before Serving: Once done, lovingly lift the chicken from the pan and let it rest for about 10 minutes. This allows the juices to redistribute, creating a juicier bite.

  7. Finish the Vegetables: Stir in tarragon and cold butter into the leeks and potatoes until melted, creating a luscious sauce to drizzle over the chicken when serving.

Optional: Garnish with fresh herbs for an extra pop of color and flavor!

Storage Tips for Whole Roast Chicken With Potatoes and Leeks

Fridge: Store leftover chicken in an airtight container for up to 3 days, ensuring it’s completely cool before sealing to maintain freshness.

Freezer: For longer storage, wrap portions tightly in plastic wrap and freeze for up to 3 months. Thaw in the fridge overnight before reheating.

Reheating: Reheat the chicken in a preheated oven at 350°F for about 20 minutes or until heated through. This will help retain the juicy flavors and crisp skin.

Whole Roast Chicken With Potatoes and Leeks Recipe FAQs

How do I select the best leeks for the recipe?
Choose leeks that are firm with a vibrant green color; they should have minimal brown spots or wilting. Look for leeks that have a thicker, more substantial base, as these tend to be sweeter and more flavorful. If possible, select leeks that still have the roots attached for optimal freshness.

What is the best way to store leftovers from the roast chicken?
After your wonderful meal, make sure to let the leftover chicken cool completely. Store it in an airtight container in the fridge for up to 3 days. To keep everything fresh, I often separate the chicken from the vegetables, placing them in different containers to prevent the potatoes from getting soggy.

Can I freeze the whole roast chicken and its sides?
Absolutely! For freezing, wrap individual portions of chicken tightly in plastic wrap or aluminum foil, and place them in a resealable freezer bag, removing as much air as possible. The roasted leeks and potatoes can be frozen in the same manner, but they may lose some texture upon reheating. These will keep well for up to 3 months. Just remember to thaw them in the refrigerator overnight before reheating!

What should I do if my chicken isn’t browning properly?
If your whole roast chicken isn t developing that golden-brown color, it could be due to several factors. First, ensure your oven is fully preheated before placing the chicken inside. If you re still struggling, try increasing the oven temperature to 400°F for the last 15-20 minutes of cooking. This added heat will help crisp up the skin beautifully! Just ensure you keep an eye on the internal temperature.

Is this dish safe for my dog to eat?
While plain chicken can be a treat for dogs, it’s essential to avoid any seasoning from the mustard rub, as some ingredients may be harmful to pets. Always check for any bones, and serve only plain cooked chicken without any skin or additional seasonings. If you’re unsure, consult your veterinarian for dietary advice specific to your furry friend!

Can I substitute any ingredients in this recipe?
Definitely! If you don t have leeks on hand, onions work as a great substitute, bringing a similar flavor profile. For the dry white wine, feel free to use chicken broth or vegetable broth for a non-alcoholic version. If whole grain mustard isn’t available, regular Dijon mustard can step in, but it may alter the flavor slightly. The more the merrier when it comes to customizing this recipe to your taste!
