This Jamie Oliver recipe combines tender chicken thighs with the subtle sweetness of leeks and the tangy kick of mustard, creating a quick and satisfying meal. Ready in just 30 minutes, it’s perfect for busy weeknights when you want something flavorful yet fuss-free.
Ingredients
- 4 boneless, skin-on chicken thighs (about 600g)
- 2 large leeks, trimmed and sliced into 1cm rounds
- 2 tablespoons wholegrain mustard
- 1 tablespoon Dijon mustard
- 2 cloves garlic, finely chopped
- 150ml chicken stock (low sodium preferred)
- 1 tablespoon olive oil
- 1 tablespoon unsalted butter
- Salt and freshly ground black pepper, to taste
- Fresh thyme sprigs (optional, about 4 sprigs)
- Juice of half a lemon
- Fresh parsley, chopped (for garnish)
Instructions
- Pat the chicken thighs dry with paper towels and season both sides generously with salt and pepper.
- Heat the olive oil in a large frying pan or skillet over medium-high heat. Once hot, add the chicken thighs skin-side down and cook for about 6-7 minutes until the skin is golden brown and crisp.
- Flip the chicken thighs and cook for another 4-5 minutes, then remove them from the pan and set aside on a plate.
- Reduce the heat to medium. Add the butter to the same pan, then add the sliced leeks and garlic. Stir frequently and cook for 4-5 minutes until the leeks have softened and started to caramelize.
- Stir in the wholegrain mustard and Dijon mustard, coating the leeks evenly.
- Pour in the chicken stock and add the fresh thyme sprigs if using. Bring the mixture to a simmer, scraping the bottom of the pan to loosen any browned bits.
- Return the chicken thighs to the pan, skin-side up. Spoon some of the sauce over the chicken and cover the pan with a lid or foil. Let everything simmer gently for 8-10 minutes, or until the chicken is cooked through and reaches an internal temperature of 75°C (165°F).
- Remove the lid and squeeze the lemon juice over the chicken. Increase the heat slightly to reduce the sauce for 2-3 minutes if needed, until it thickens slightly.
- Check the seasoning and adjust with salt and pepper as necessary. Scatter chopped parsley over the dish before serving.
Tips
- Substitution for chicken thighs: You can use skin-on chicken breasts if preferred, but reduce cooking time to avoid drying out. Bone-in thighs also work but will take longer to cook through.
- Leek preparation: Leeks can hold grit between their layers. Rinse them well in cold water after slicing to ensure no dirt remains.
- Mustard options: If you don’t have wholegrain mustard, substitute with 3 tablespoons of Dijon or English mustard, but adjust quantity to taste as it’s sharper.
- Common mistake: Avoid overcrowding the pan when browning the chicken; cook in batches if necessary for a crisp skin.
Serving Suggestions
This dish pairs beautifully with creamy mashed potatoes or buttery new potatoes to soak up the mustard sauce. For a lighter option, serve alongside steamed green beans or a simple mixed leaf salad dressed with olive oil and lemon. Crusty bread is also excellent for mopping up any leftover sauce on the plate.
Variations
To add more depth, try incorporating chopped mushrooms or sliced carrots with the leeks for extra texture and flavor. For a smoky twist, add a teaspoon of smoked paprika when cooking the leeks. You can also swap the chicken stock for white wine for a slightly richer sauce, allowing it to reduce before adding the stock. If you prefer a creamier sauce, stir in 2 tablespoons of crème fraîche or double cream at the end, just before serving.
Storage and Reheating
Store any leftovers in an airtight container in the refrigerator for up to 2 days. When reheating, warm gently in a saucepan over low heat, adding a splash of water or stock to loosen the sauce if it has thickened. Alternatively, microwave on medium power until heated through, stirring halfway. Avoid reheating multiple times to maintain quality and food safety.
Frequently Asked Questions
Can I use frozen chicken thighs for this recipe?
Yes, frozen chicken thighs can be used but make sure to fully thaw them in the refrigerator overnight before cooking. Cooking from frozen will result in uneven cooking and longer times, which can affect texture and safety.
What if I don’t have leeks—can I substitute with onions?
Absolutely, sliced onions work well as a substitute. They will provide a sweeter and more pungent flavor compared to the mild sweetness of leeks. Cook them gently to avoid burning.
How do I know when the chicken is fully cooked?
The safest way is to check the internal temperature with a meat thermometer. It should read at least 75°C (165°F). The juices should run clear, and the meat should not be pink inside.
Is this recipe suitable for meal prep?
Yes, this dish reheats well and can be prepared ahead of time. Keep the sauce and chicken together to maintain moisture. It’s ideal for quick lunches or dinners throughout the week.
Can I make this recipe dairy-free?
Yes, simply replace the butter with an extra tablespoon of olive oil or a dairy-free margarine. The rest of the ingredients are naturally dairy-free, so the flavor will remain intact.
What wine pairs well with this chicken dish?
A crisp white wine like Sauvignon Blanc or a light Chardonnay complements the mustard’s tang and the leeks’ sweetness nicely. For a red, opt for a light-bodied Pinot Noir.
This Jamie Oliver chicken with mustard and leeks recipe is a great example of how simple ingredients can come together quickly to create a comforting, flavorful meal. With its ease and versatility, it’s sure to become a staple in your weeknight rotation.
