Simple ingredients that transform into Jamie Oliver's signature crispy, saucy masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless, Skinless Chicken Thighs 🍗 | 1 ½ lb | Cut into even-sized pieces |
| Celery Stalks 🧅 | 2 whole | Cut into 1-inch thick crowns |
| White Button Mushrooms 🍄 | 1 ½ lb | Sliced into even pieces |
| Garlic Cloves 🧄 | 6 cloves | Minced for sauce base |
| Shallots 🧅 | 2 whole | Finely chopped |
| Chicken Broth 💧 | 1 cup | Low-sodium preferred |
| Dry White Wine 🍷 | ½ cup | Sauvignon Blanc recommended |
| Heavy Cream 🥛 | ½ cup | Full-fat for richness |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For crisping celery crowns |
| All-Purpose Flour 🌾 | ½ cup | For breading celery crowns |
| Dried Thyme 🍃 | 1 tsp | Or 1 tbsp fresh thyme |
| Dried Rosemary 🌿 | ½ tsp | Crushed between fingers |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Fresh Parsley 🌿 | ¼ cup | Chopped for garnish |
The celery crowns are the star here—they need to be 1-inch thick for perfect crispiness. Look for fresh, firm stalks with vibrant green leaves at the grocery store. Whole Foods or Trader Joe's carry the best quality, but any well-stocked supermarket will do. The chicken thighs should have visible fat marbling—this keeps them juicy during baking. If you can't find thighs, use boneless, skinless breasts but pound them thin to ensure even cooking. The mushrooms should be white and firm, not slimy or discolored. Slice them evenly so they cook at the same rate as the chicken.
No white wine? Chicken broth with a splash of lemon juice works perfectly. Fresh thyme and rosemary are ideal, but dried works at one-third the amount if that's all you have. The shallots can be swapped for 1 small yellow onion, finely chopped. For extra richness, add 1 tbsp of cream cheese to the sauce—it blends right in. The celery crowns should be lightly coated with flour before baking, but don't overdo it or they'll lose their crispiness. If you're short on time, pre-cut celery crowns are available at specialty stores like Williams Sonoma.
This dish reheats beautifully—cover with foil and bake at 375°F for 10 minutes to revive the crispiness. Store leftovers in the fridge for up to 3 days, though the celery crowns lose their crunch after the first day. For longer storage, freeze the sauce separately and reheat it with the chicken and mushrooms—just add a splash of water or broth to loosen it. The celery crowns don't freeze well, so it's best to make them fresh or enjoy them the same day. Garnish with fresh parsley right before serving for a pop of color.
Why You'll Love This Recipe
- One-Pan Magic: I swear by this recipe when I’m too tired to scrub pots—just toss the chicken thighs, mushrooms, and chopped shallots on a sheet pan, drizzle with olive oil, and let the oven do the work. The celery and garlic roast right alongside, turning tender without any fuss.
- Umami Bomb: That combo of earthy mushrooms, sharp shallots, and juicy chicken thighs? It’s like a flavor party in your mouth. The garlic cloves get caramelized just enough to add a sweet, punchy depth—no one will guess it’s this simple.
- Leftovers That Don’t Suck: Between us, most tray bakes turn into sad, dry leftovers. Not this one. The chicken stays juicy, and the mushrooms soak up all the good stuff, so reheating it the next day is just as satisfying. (Yes, even on a Tuesday night.)
- Budget-Friendly Feast: Chicken thighs and mushrooms are cheap, but they feel fancy. I make this for date nights or when friends drop by—no one ever questions the price tag, and my wallet stays happy. Plus, the celery stretches the veggie budget without sacrificing flavor.
Step-by-step instructions for chicken and mushroom tray bake
Here's how to create a restaurant-quality tray bake with perfectly crispy celery crowns and a rich mushroom sauce.
Prepare the Celery Crowns for Crisping
Start by cutting the 2 whole celery stalks into 1-inch thick crowns, keeping the leafy tops intact. In a small bowl, combine the 0.5 cup all-purpose flour, 1.5 teaspoons salt, 0.5 teaspoon black pepper, 1 teaspoon dried thyme, and 0.5 teaspoon crushed dried rosemary. Toss the celery crowns in this flour mixture until they're evenly coated.
Heat 1 tablespoon of the 2 tablespoons extra-virgin olive oil in a large oven-safe skillet over medium-high heat. Once shimmering, add the celery crowns in a single layer and cook for 3-4 minutes until golden brown on one side. Flip carefully and cook for another 3-4 minutes until deeply crispy and golden on both sides. Transfer to a plate and set aside.
Cook the Chicken Thighs
In the same skillet, add the remaining 1 tablespoon extra-virgin olive oil over medium heat. Working in batches if needed, add the 1.5 lb boneless, skinless chicken thighs, cut side down. Cook for 5-6 minutes until golden brown and crispy on the bottom. Flip and cook for another 4-5 minutes until the internal temperature reaches 165°F. Remove from skillet and set aside with the celery crowns.
Real talk: Don't overcrowd the skillet or the chicken will steam instead of crisp. If needed, work in batches and keep the cooked pieces warm in a 200°F oven. The chicken should develop a nice golden crust while staying juicy inside.
Build the Mushroom Sauce
In the same skillet, add the 1.5 lb sliced white button mushrooms and cook over medium heat for 5-6 minutes until they release their moisture and begin to brown. Add the 2 finely chopped shallots and 6 minced garlic cloves, cooking for another 2-3 minutes until fragrant and softened.
Pour in the 0.5 cup dry white wine and scrape up any browned bits from the bottom of the pan. Let it simmer for 3-4 minutes until the wine reduces by half. Add the 1 cup chicken broth and bring to a gentle simmer, then reduce heat to low and let it cook for 5 minutes to develop flavor.
Finish with Cream and Assemble
Stir in the 0.5 cup heavy cream, 1 teaspoon dried thyme, and 0.5 teaspoon crushed dried rosemary. Let the sauce simmer gently for 3-4 minutes until slightly thickened. Taste and adjust seasoning with additional salt and pepper if needed.
Return the chicken thighs and celery crowns to the skillet, spooning the sauce over the top. Cover and transfer to a preheated 375°F oven for 10-12 minutes, allowing everything to heat through and the flavors to meld. The celery should be warmed through but still crisp, and the chicken should be fully cooked.
Garnish and Serve
Remove from the oven and transfer to serving plates. Spoon any remaining sauce from the skillet over the top. Garnish with the 0.25 cup chopped fresh parsley just before serving. The dish should have beautiful golden-brown crispy celery crowns, tender chicken thighs, and a rich, velvety mushroom sauce.
Serve immediately with crusty bread or roasted potatoes to soak up the delicious sauce. The contrast between the crispy celery crowns and the creamy mushroom sauce makes this dish truly special.
Pro Tips For Making Jamie Oliver Chicken And Mushroom Tray Bake
- CRISP THE MUSHROOMS FIRST: I learned this the hard way—skipping the quick sear in a hot pan before baking means soggy mushrooms instead of golden, flavor-packed ones. Hit them with oil, salt, and a splash of white wine (if using) until they release their moisture and develop edges. This isn’t just about looks; it builds depth that baking alone can’t match.
- SLICE SHALLOTS THINLY: Thick rings turn to mush in the oven while chicken cooks. Grab a sharp knife and slice them paper-thin—almost translucent—so they soften into the sauce without disappearing. (Yes, even if you’re impatient like me, resist the urge to eyeball it.)
- DON’T OVERCROWD THE TRAY: I used to jam everything in there like a sardine can, and the chicken ended up steaming instead of browning. Leave at least ½ inch of space between thighs and veggies—crowding traps moisture, turning your crispy dream into a sad, sticky mess. If needed, bake in batches or use two trays.
- SEAR CHICKEN BEFORE BAKE: This isn’t just for show—it locks in juices and gives the dish that restaurant-worthy crust. Pat the thighs very dry, then hit them with oil and salt in a hot pan for 3–4 minutes per side until golden. The residual heat carries through the bake, guaranteeing tender meat with a caramelized edge. (Your future self will thank you.)
Wine and beer pairings for this dish
Crisp White Wine
A Sauvignon Blanc from New Zealand or Loire Valley is my go-to pairing for this dish—its bright acidity and citrus notes cut through the richness of the mushroom sauce while complementing the earthy mushrooms.
Look for a 2022 vintage from Cloudy Bay or Oyster Bay; they’re widely available and offer that perfect balance. Serve slightly chilled (45-50°F) to enhance the wine’s crispness against the warm, creamy sauce. 🍷
Earthy Pinot Noir
For a red wine option, a light-bodied Pinot Noir from Oregon’s Willamette Valley works beautifully. The Pinot Noir’s red fruit flavors and subtle earthiness mirror the mushrooms in the dish, while its acidity keeps the palate fresh.
I recommend a 2021 Domaine Serene or La Crema—both are approachable and won’t overpower the delicate flavors. Serve at 55-60°F to let its aromas shine alongside the dish’s savory notes.
Craft Beer Pairing
A Belgian-style witbier like Hoegaarden or Stella Artois is my favorite beer match—its coriander and citrus notes provide a refreshing contrast to the creamy sauce and crispy celery. The slight effervescence also cleanses the palate between bites.
For a darker option, try a German Helles Lager like Weihenstephaner Original, which offers a malty balance without overwhelming the dish’s flavors. Serve both at 40-45°F for the best experience. 🍺
Unexpected Sparkling Option
Don’t overlook a dry sparkling wine like Prosecco or Cava for a lighter pairing. The bubbles and acidity make it a fantastic match for the creamy sauce, while the slight sweetness in Prosecco complements the caramelized mushrooms.
I love pairing this with La Marca Prosecco or Freixenet Cordon Negro Cava—both are budget-friendly and widely available. Serve well-chilled (40-45°F) to highlight its crispness.
Non-Alcoholic Match
For a non-alcoholic option, a sparkling apple cider like Martinelli’s or a ginger beer such as Feather’s works surprisingly well. The effervescence and slight sweetness in apple cider balance the richness of the dish, while the ginger beer’s spice adds a refreshing contrast.
Serve both over ice to keep them crisp and refreshing. 💛

Frequently asked questions
Can I use chicken breasts instead of thighs?
Yes, but with caution! Chicken breasts cook faster and can dry out. Pound them to ½-inch thickness and bake for 8-10 minutes instead of 10-12 minutes in the final oven step. For extra juiciness, marinate them in 1 tablespoon olive oil + 1 teaspoon lemon juice for 15 minutes before cooking.
What if I don’t have white wine?
No problem! Replace it with ½ cup chicken broth + 1 teaspoon lemon juice—it’ll mimic the acidity. For extra depth, add ½ teaspoon soy sauce or 1 teaspoon balsamic vinegar. The sauce will still develop rich flavor, just with a slightly different profile.
How do I keep the celery crowns crispy?
Timing is key! Cook them in batches over medium-high heat until golden brown (3-4 minutes per side). Avoid overcrowding the pan, and don’t skip the flour coating—it’s what creates the crispy texture. If they soften during baking, broil for 1-2 minutes at the end.
Can I make this ahead of time?
Assemble the dish (except the celery crowns) up to 24 hours ahead and refrigerate. When ready to cook, bake at 375°F for 15-20 minutes (covered) to reheat. For the celery crowns, make them fresh or toast them in the oven for 3-4 minutes at 400°F to restore crispness.
What’s the secret to the creamy mushroom sauce?
Deglaze the pan after cooking the mushrooms—those browned bits (fond) add deep flavor. Simmer the sauce uncovered for 5 minutes to reduce and thicken it naturally. Stir in the cream off the heat to prevent curdling, and always taste before serving. A pinch of salt or black pepper can elevate it further.
