Ingredients for jamie oliver chicken and mushroom tray bake
Crispy chicken, caramelized celery, and earthy mushrooms baked in a rich herb sauce—this tray bake delivers restaurant-quality flavor with simple ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| Chicken Thighs 🍗 | 1 ½ lb | Bone-in, skin-on for crispiness |
| Celery Stalks 🥬 | 3 whole | Trimmed, cut into 1-inch pieces |
| White Button Mushrooms 🍄 | 1 lb | Quartered, stems removed |
| Fresh Rosemary 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Thyme 🍃 | ¼ cup | Leaves only, finely chopped |
| Garlic Cloves 🧄 | 4 cloves | Minced, for sauce base |
| Extra-Virgin Olive Oil 🫒 | ½ cup | For crisping chicken |
| Unsalted Butter 🧈 | ¼ cup | Cold, for extra richness |
| Chicken Broth 💧 | ½ cup | Low-sodium preferred |
| Heavy Cream 🥛 | ¼ cup | Full-fat for creaminess |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Kosher Salt 🧂 | 1 ½ tsp | Adjust to taste |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Dried Parsley 🌿 | 1 tsp | For garnish |
The chicken thighs are the star—bone-in and skin-on for that perfect crispy exterior while staying juicy inside. Look for thighs with good marbling at your local butcher or grocery store's meat counter. If using pre-cut thighs, pat them dry with paper towels (the crispier the skin, the better). For the mushrooms, white button mushrooms work best—they caramelize beautifully and won’t turn bitter. If you’re feeling fancy, swap in cremini or shiitake mushrooms for extra depth of flavor. The celery should be fresh and crisp, with no brown spots or wilted ends—Whole Foods or local farmers markets usually carry the freshest stalks.
No fresh rosemary? Dried rosemary works at half the amount, but fresh gives the best aroma. Short on thyme? Fresh oregano or marjoram can stand in, though the flavor will differ slightly. The olive oil and butter combo is key for that golden crust—use high-quality extra-virgin olive oil (like California Olive Ranch) and unsalted butter (the salt content is controlled separately). For the broth, low-sodium options prevent over-salting the dish. The heavy cream adds richness, but if you’re watching calories, half-and-half or whole milk works in a pinch (though the sauce won’t be as velvety).
This dish reheats beautifully—just pop it back in the oven at 375°F for 10-15 minutes until everything is heated through. The herb sauce thickens as it cools, so if it seems too thin after baking, simmer it uncovered for 2-3 minutes to reduce. Store leftovers in an airtight container in the fridge for up to 4 days, or freeze for 3 months. For make-ahead prep, assemble the tray bake the night before and refrigerate uncovered (this helps crisp the chicken skin even more). Garnish with fresh parsley just before serving to keep it vibrant.

Step-by-step instructions for chicken and mushroom tray bake
Here's how to create golden, crispy chicken with tender mushrooms in a rich herb sauce.
🔥 Step 1: Create the Celery Crowns and Crisp the Chicken
Preheat your oven to 425°F. Cut the 3 whole celery stalks into 1-inch pieces and set aside. Pat the 1.5 lb chicken thighs dry with paper towels—this is crucial for crispy skin. Place them skin-side up on a baking sheet lined with parchment paper.
In a small bowl, mix 1.5 tsp kosher salt, 0.5 tsp ground black pepper, and 1 tbsp lemon juice. Rub this mixture all over the chicken, pressing gently to adhere. Drizzle 0.5 cup extra-virgin olive oil evenly over the chicken and celery pieces. Bake for 25 minutes until the chicken skin is golden brown and crispy, and the celery starts to soften slightly.
🍳 Step 2: Build the Herb Sauce Base
While the chicken cooks, heat 0.25 cup unsalted butter in a saucepan over medium heat. Add the 4 cloves minced garlic and cook for 30 seconds until fragrant—don't let it brown. Stir in the 0.25 cup chopped fresh rosemary and 0.25 cup chopped fresh thyme, cooking for another 1 minute to release their aromatic oils.
Pour in the 0.5 cup chicken broth and bring to a gentle simmer. Let it reduce by half, about 5 minutes, until the mixture thickens slightly. This creates a flavorful foundation for your sauce. Remove from heat and stir in the 0.25 cup heavy cream—it should be warm but not boiling to prevent curdling.
🥘 Step 3: Combine and Finish in the Oven
Carefully transfer the partially cooked chicken and celery to a large baking dish. Pour the herb sauce evenly over the top, making sure every piece is coated. Scatter the 1 lb quartered white button mushrooms over the chicken, arranging them in an even layer. Return to the oven and bake for an additional 20-25 minutes until the chicken reaches an internal temperature of 165°F and the mushrooms are tender.
The mushrooms should be golden around the edges and the sauce should be thickened and glossy. If the sauce looks too thin after baking, remove the dish from the oven and simmer uncovered for 2-3 minutes to reduce it slightly. Sprinkle with 1 tsp dried parsley just before serving for a fresh finish.
Pro Tips For Making Jamie Oliver Chicken And Mushroom Tray Bake
- Don’t Rush the Butter: Let that cold 0.25 cup unsalted butter melt slowly over medium heat—no rushing. I used to crank the heat and end up with splattered garlic. Thirty seconds for fragrant, not browned, is where the magic happens.
- Trim Mushroom Stems First: Remove the stems from the 1 lb white button mushrooms before quartering—it’s a pain, but they turn to mush and ruin the sauce. Trust me, your future self will hate scraping them out later.
- Baste the Chicken Mid-Bake: After the first 15 minutes at 425°F, pull the tray out and spoon the drippings over the chicken. The extra moisture keeps the skin crispy while the meat stays juicy—no dry, sad thighs here.
- Use Room-Temp Cream: Take the 0.25 cup heavy cream out of the fridge 10 minutes before using. Cold cream can curdle when you stir it into the hot broth—warm but not boiling is the sweet spot, and it makes the sauce silky.
Storing and reheating your jamie oliver chicken and mushroom tray bake
Fridge Storage Tips
Transfer your tray bake to an airtight container within 2 hours of baking to preserve crispness. I use glass Pyrex containers because they keep flavors fresh longer than plastic. Store at 40°F or below—the sauce will thicken slightly overnight, intensifying the flavors. 💡
Make-Ahead Magic
This dish actually tastes better the next day! Assemble the tray bake the night before, refrigerate uncovered, and bake straight from cold at 400°F for 35-40 minutes.
The cold chicken crisps up beautifully, and the celery develops deeper caramelization. I've done this for busy weeknights and it's always a hit.
Freezing For Later
Freeze your tray bake in portions for up to 3 months using flat freezer bags. Squeeze out all air first to prevent freezer burn. When ready to eat, thaw overnight in the fridge then reheat at 375°F for 20-25 minutes until piping hot.
The texture stays excellent—just add a splash of water if it looks dry.
Reheating Like a Pro
For best results, reheat in the oven at 375°F for 15-20 minutes until the internal temperature reaches 165°F. This maintains that perfect crispy skin. If using a microwave, cover loosely with a damp paper towel and heat on medium for 2-3 minutes, stirring halfway.
The sauce may separate slightly—just give it a quick stir before serving.
Sauce Adjustments
If your sauce looks watery after reheating, simmer uncovered for 2-3 minutes to reduce. For extra richness, stir in 1 tbsp cold butter while reheating. I also like to add 1 tsp fresh lemon juice at the end to brighten the flavors—it's a simple trick that makes all the difference.
This dish always tastes better the second time around!

Frequently asked questions
Why does this recipe use bone-in, skin-on chicken thighs?
The bone-in, skin-on chicken thighs create the perfect balance of crispy skin and juicy meat—essential for Jamie Oliver’s signature texture. The skin crisps beautifully in the oven while the bone adds rich flavor to the dish. Plus, they stay moist longer than boneless cuts!
Can I substitute fresh herbs with dried ones?
Yes, but adjust the amounts! Use half the quantity of dried rosemary and thyme compared to fresh. For example, 1 tablespoon dried rosemary instead of 0.25 cup fresh. Dried herbs are more concentrated, so they’ll still pack plenty of flavor.
What if my sauce is too thin after baking?
No problem! Simply remove the dish from the oven and simmer the sauce uncovered for 2-3 minutes to reduce it. If it’s still thin, stir in 1 tablespoon cold butter while reheating to add richness. A splash of lemon juice at the end brightens flavors too.
Is it safe to eat leftovers after 4 days?
Yes, but only if stored properly in an airtight container. After 4 days, reheat thoroughly to 165°F to ensure safety. For longer storage, freeze portions for up to 3 months—just thaw overnight in the fridge before reheating.
