Ingredients for jamie oliver chicken and mushroom tray bake

Fourteen ingredients, one pan, restaurant-quality dinner in under an hour—herbs and mushrooms take center stage.

The chicken thighs are non-negotiable here—bone-in, skin-on delivers that golden, crispy finish Jamie Oliver loves. Most grocery stores carry them pre-cut, but if you're buying whole, look for evenly sized thighs with good marbling. Trader Joe's and Whole Foods often have excellent quality, but any well-stocked supermarket will do. Fresh mushrooms are key: cremini and shiitake add the earthy depth this dish needs, but a mix of button mushrooms works in a pinch. Pat them dry before cooking to maximize browning. For the herbs, fresh rosemary and thyme from the grocery store's produce section are ideal, but dried will work at half the amount if you're in a hurry.

No Dijon mustard? Whole-grain mustard thinned with a splash of water gets you close. Short on heavy cream? Half-and-half or whole milk adds richness, though the texture will be slightly lighter. The chicken stock can be low-sodium bouillon if you're in a bind, but homemade is always better. For the shallots, yellow onions work in a pinch—just remember to finely dice them. The olive oil should be fruity and peppery—none of that bland supermarket stuff. If you're feeling fancy, Penzeys or local olive oil shops have excellent options, but a good-quality store brand works too. The butter? Cold and cubed is crucial for proper browning—don't skip this step!

This dish reheats beautifully—350°F for 10-15 minutes brings it back to life. Store leftovers in an airtight container for up to 4 days in the fridge, or freeze for 3 months. The herby sauce thickens as it cools, so you can thin it with a splash of warm water or stock if needed. For meal prep, portion the chicken and mushrooms separately—they hold up better that way. The sauce freezes well too, just reheat it gently on the stove. Crusty bread is the perfect side, but a simple arugula salad with lemon vinaigrette cuts through the richness beautifully.

Step-by-step instructions for herb-infused one-pan chicken and mushrooms

This one-pan wonder delivers restaurant-quality flavor with minimal cleanup—perfect for weeknight dinners.

Preheat your oven to 400°F. Heat 2 tablespoons of the extra-virgin olive oil in a large oven-safe skillet over medium-high heat. Pat the 1.5 lb chicken thighs dry with paper towels and season generously with 1 teaspoon of the salt and ¼ teaspoon of the ground black pepper.

Place the chicken thighs skin-side down in the skillet and cook undisturbed for 5-6 minutes until the skin is deep golden brown and crispy. Flip the chicken and cook for another 3-4 minutes until the internal temperature reaches 165°F. Remove the chicken and set aside on a plate, leaving the rendered fat in the pan.

In the same skillet, add the remaining 3 tablespoons unsalted butter and 2 tablespoons extra-virgin olive oil. Once melted, add the 16 oz mixed mushrooms and cook for 5-6 minutes until they release their moisture and begin to brown. Stir occasionally to ensure even cooking.

Add the 2 finely diced shallots and cook for 2 minutes until softened. Stir in the 6 minced garlic cloves and cook for 30 seconds until fragrant—this is where the magic happens. Sprinkle with the remaining ½ teaspoon salt and ¼ teaspoon black pepper.

Reduce heat to medium and add the 1 tbsp Dijon mustard and 1 tbsp all-purpose flour. Stir for 1 minute to cook out the raw flour taste. Slowly pour in the ½ cup chicken stock while stirring constantly to prevent lumps from forming.

Bring the mixture to a gentle simmer for 2-3 minutes until slightly thickened. Stir in the ½ cup heavy cream and remove from heat. Add the ¼ cup chopped fresh rosemary and ¼ cup chopped fresh thyme, stirring just until combined. The herbs should infuse the sauce with their bright, aromatic flavors.

Return the chicken thighs to the skillet, spooning the mushroom sauce over the top. Place the skillet in the preheated 400°F oven and bake for 20-25 minutes until the chicken is cooked through and the sauce has thickened to a glossy consistency.

For the final touch, broil on high for 2-3 minutes until the sauce bubbles and the chicken skin turns beautifully crispy. Watch closely to avoid burning. Remove from the oven and let rest for 5 minutes before serving.

Transfer the chicken and mushrooms to a serving platter, spooning any remaining sauce over the top. Garnish with additional fresh rosemary and thyme sprigs for a pop of color and extra herbaceous flavor. Serve immediately with crusty bread or over mashed potatoes to soak up every last bit of that luscious sauce.

Each bite delivers tender, juicy chicken with earthy mushrooms in a rich, herby sauce that's perfect for a satisfying weeknight meal. The one-pan method keeps cleanup to a minimum while delivering maximum flavor—just like Jamie would make it.

Best sauces and condiments for this recipe

Herb-Infused Cream Sauce

The star of this tray bake is the herb-infused cream sauce, where Dijon mustard and fresh rosemary create a perfect balance of tangy and aromatic notes. I always add the herbs at the very end to preserve their bright flavors—stirring just enough to infuse without overpowering.

For extra depth, a splash of white wine (about 2 tbsp) during the sauce-building step elevates the dish to restaurant-quality. 🌿

Garlic-Butter Mushroom Base

The mushrooms get their rich flavor from 3 tbsp unsalted butter and 6 minced garlic cloves, which caramelize beautifully during the 5-6 minute sauté. I recommend using a mix of cremini and shiitake for that earthy umami punch, but button mushrooms work in a pinch.

For a smoky twist, add ½ tsp smoked paprika when sautéing the mushrooms—it pairs wonderfully with the herby sauce. 🍄

Creamy Mustard Glaze

The Dijon mustard in this sauce isn’t just for flavor—it adds a subtle tang that cuts through the richness of the cream. For a smoother texture, whisk the mustard with 1 tbsp flour before adding it to the pan.

If you prefer a glossier finish, reduce the sauce by 2-3 minutes on the stove after baking. A drizzle of truffle oil (just ½ tsp) at the end adds a luxurious touch that guests will love. 💫

Pan Sauce Upgrade

Don’t waste that golden brown chicken fat left in the pan after searing! Deglaze it with 2 tbsp white wine or chicken stock before building the sauce—this adds 30% more flavor to the final dish.

For a spicy kick, stir in ½ tsp red pepper flakes at the end. This technique is a game-changer, especially if you’re serving the dish to heat-loving guests. 🌶️

Fresh Herb Garnish

Fresh herbs aren’t just for decoration—they add bright, aromatic notes that elevate every bite. Sprinkle chopped rosemary and thyme over the finished dish right before serving. For a gourmet touch, add thinly sliced shallots or crispy fried shallots to contrast the creamy sauce.

I also like a sprinkle of flaky sea salt (like Maldon) for a finishing pop of texture. ✨

Alternative Sauce Options

If you’re not a fan of cream-based sauces, swap it out for a white wine reduction by simmering ½ cup white wine with 1 tbsp butter, 1 tsp Dijon, and 1 tsp lemon juice until slightly thickened.

For a lighter option, use Greek yogurt (mixed with 1 tbsp sour cream) instead of heavy cream—it’s tangy and still rich. Both alternatives keep the dish balanced while offering a different texture. 🍷
