Ingredients for jamie oliver chicken and mushroom tray bake
Simple ingredients that become restaurant-worthy with one pan and 45 minutes of hands-off magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Chicken Thighs 🍗 | 1 ½ lb | Bone-in, skin-on preferred |
| Cremini Mushrooms 🍄 | 1 lb | Stemmed, sliced into halves |
| Baby Potatoes 🥔 | 1 ½ lb | Halved, skin-on |
| Fresh Thyme 🌿 | ¼ cup | Stems removed, loosely packed |
| Garlic Cloves 🧄 | 4 cloves | Minced, fresh preferred |
| Extra-Virgin Olive Oil 🫒 | ⅓ cup | For tossing and roasting |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed |
| Dijon Mustard 🍯 | 1 tbsp | For marinade depth |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Ground Black Pepper 🌶️ | 1 tsp | Freshly cracked |
| Dried Oregano 🍃 | 1 tsp | For extra herby notes |
| Fresh Rosemary 🌿 | 1 tbsp | Chopped, stems removed |
| Butter 🧈 | 2 tbsp | Cold, cubed for tossing |
The chicken thighs are the star here—bone-in, skin-on gives you that crispy, juicy perfection. Trader Joe's or Whole Foods usually have the best quality, but any grocery store's butcher section works. Look for thighs with good marbling—they stay juicier. I always grab extra because they're so versatile. For the mushrooms, cremini is ideal, but white or baby bella work too. Just make sure they're firm and free of dirt. The potatoes? Baby potatoes are perfect for this—halving them ensures even cooking. Costco sells them in bulk, which saves money for leftovers.
No fresh thyme? Dried works at half the amount, but fresh is worth hunting down at the farmers market. The Dijon mustard can be swapped for regular mustard if that's what you've got, but the Dijon adds that extra depth. Short on garlic? Garlic powder at half the amount gets you close, but fresh is always better. The olive oil matters—use something fruity and peppery. California Olive Ranch is my go-to, but any extra-virgin will do. And if you're out of rosemary, fresh basil or parsley can stand in for a similar fresh, bright note.
This dish reheats beautifully—honestly tastes better the next day once all the flavors meld. Store leftovers in an airtight container for 4-5 days. For meal prep, I portion it into containers so lunches are sorted for the week. The potatoes get extra crispy when reheated, so a quick broil for 2-3 minutes brings them back to life. Freezes well for 3 months if you want to make a big batch ahead of time. Just thaw overnight in the fridge before reheating.

Step-by-step instructions for herb-roasted chicken and mushroom tray bake
Here's how to create Jamie Oliver's signature one-pan wonder with crispy skin and tender flavors.
🍳 Step 1: Prep and Marinate the Chicken
Start by patting the 1.5 lb chicken thighs completely dry with paper towels. This step is crucial—wet skin won't crisp up properly. In a bowl, whisk together 0.33 cup extra-virgin olive oil, 2 tbsp lemon juice, 1 tbsp Dijon mustard, 1.5 tsp salt, 1 tsp ground black pepper, 1 tsp dried oregano, and 1 tbsp chopped fresh rosemary. Pour this marinade over the chicken and toss to coat evenly.
Let the chicken marinate for at least 15 minutes at room temperature. This gives the flavors time to penetrate and helps prevent dryness during roasting. If you have time, marinate for up to 30 minutes—the longer it sits, the more flavorful the result.
👨🍳 Step 2: Prepare the Potatoes and Mushrooms
While the chicken marinates, halve the 1.5 lb baby potatoes (skin-on) and toss them in a large bowl with 1 tbsp chopped fresh rosemary, 0.25 cup fresh thyme, 1 tsp dried oregano, 1 tsp salt, and 0.5 tsp black pepper. The potatoes should be well coated but not soggy. Set aside.
Slice the 1 lb cremini mushrooms in half and place them in a separate bowl. Drizzle with 1 tbsp extra-virgin olive oil and toss to coat evenly. Sprinkle with 0.5 tsp salt and 0.5 tsp black pepper. The mushrooms will release their juices as they roast, creating a rich sauce.
🔥 Step 3: Roast the Chicken and Potatoes
Preheat your oven to 425°F. Arrange the marinated chicken thighs skin-side up on a large baking sheet lined with parchment paper. Scatter the seasoned potatoes around the chicken, leaving space for the mushrooms. Roast for 20 minutes to get the chicken skin crispy and the potatoes starting to soften.
After 20 minutes, carefully flip the chicken thighs and push them to one side of the pan. Add the prepared mushrooms to the empty space, spreading them out in a single layer. This creates room for everything to roast evenly without steaming.
🥘 Step 4: Finish with Butter and Herbs
Return the baking sheet to the oven and roast for another 15-20 minutes until the chicken skin is deep golden brown and crispy, and the potatoes are tender when pierced with a fork. The mushrooms should be golden and slightly caramelized at the edges.
Remove the baking sheet from the oven and sprinkle the 2 tbsp cold cubed butter evenly over the chicken, potatoes, and mushrooms. Return the pan to the oven for 2-3 minutes just to melt the butter and create a glossy finish. Watch closely—you want the butter to melt and coat everything but not burn.
⏰ Step 5: Rest and Serve
Let the tray bake rest for 5 minutes before serving. This allows the juices to redistribute in the chicken, keeping it moist and flavorful. The potatoes and mushrooms will stay warm while you plate everything.
Serve directly from the baking sheet for easy cleanup, or transfer to a platter. The chicken should have crispy, golden skin that gives way to tender meat, while the potatoes will be soft inside with crispy edges. The mushrooms should be juicy and infused with herby flavors from the roasting process.
Pro Tips For Making Jamie Oliver Chicken And Mushroom Tray Bake
- CRISP THE POTATOES FIRST: Roast the baby potatoes for 15 minutes at 220°C (425°F) before adding anything else—this gets them properly crispy on the outside while keeping them tender inside. I used to skip this and ended up with soggy spuds that tasted like boiled potatoes in disguise.
- SCORE THE CHICKEN SKIN: Use a sharp knife to make shallow cuts (about 1cm deep) in the chicken thighs before baking—this lets fat render out and the skin get extra crispy. After burning my first batch trying to "press" the skin flat, I realized scoring does the job without the mess.
- DON’T OVERCROWD THE MUSHROOMS: Spread the cremini mushrooms in a single layer with space between them, or bake them in batches if needed. I learned this the hard way when my tray ended up steaming instead of browning—now they get golden and caramelized, not sad and damp.
- USE GARLIC BUTTER INSTEAD OF MINCE: Mash 2 cloves of garlic with 2 tablespoons of softened butter before spreading it over the chicken and mushrooms—it sticks better and adds richness without burning. I was skeptical until I tried it; now it’s the thing that makes this dish taste restaurant-worthy.
Dietary considerations for jamie oliver chicken and mushroom tray bake
Gluten-Free Adaptation
This dish is naturally gluten-free if you use certified gluten-free Dijon mustard and check your dried herbs for cross-contamination. I always keep Annie's gluten-free mustard on hand for these recipes. The key is ensuring no shared equipment with gluten-containing ingredients—my Lodge cast iron skillet stays dedicated to gluten-free cooking. 🌾
Dairy-Free Options
For a dairy-free version, simply omit the butter and use 2 tbsp olive oil or Earth Balance vegan butter instead. The dish maintains all its herby richness without dairy. I've tested this with Miyoko's vegan butter and found it adds a lovely depth to the roasted flavors.
Lower-Carb Modifications
Swap the potatoes for cauliflower florets or zucchini slices to cut carbs while keeping the meal satisfying. Toss the veggies in the same herb-oil mix and roast alongside the chicken. The mushrooms provide plenty of umami to keep the dish flavorful without the potatoes.
Protein Swaps
For a vegetarian version, replace the chicken with extra-firm tofu or chickpeas. Press and marinate the tofu in the same herb-lemon mixture for 20 minutes, then roast it alongside the mushrooms. Chickpeas work well too—just toss them in the marinade and roast until crispy. 💚
Allergen-Friendly Tips
If nut allergies are a concern, avoid any cross-contamination with nut oils or shared equipment. I keep separate utensils and baking sheets for nut-free cooking. For soy allergies, check your mustard brands—some contain soy. Primal Kitchen offers soy-free mustard alternatives that work perfectly in this recipe.

Frequently asked questions
Can I use chicken breasts instead of thighs in this recipe?
Chicken breasts will work, but they require extra care to stay juicy. Use bone-in, skin-on breasts and reduce the oven temperature to 375°F to prevent drying. Baste with marinade every 10 minutes and add 1 tbsp olive oil to the pan halfway through roasting. Cook for 25-30 minutes total, checking at 20 minutes.
What's the best way to reheat leftovers?
Reheat leftovers in a 350°F oven for 15-20 minutes to maintain crispiness. For extra crunch, broil for 2-3 minutes at the end. Alternatively, warm in a skillet over medium heat with 1 tbsp butter for 3-4 minutes per side. Never microwave—it makes the skin rubbery.
Can I make this recipe ahead of time?
Assemble the tray bake up to 24 hours ahead and refrigerate uncovered. Roast directly from the fridge at 425°F, adding 5-10 extra minutes to the cooking time. For freezing, bake completely, cool, then store in an airtight container for up to 3 months. Thaw overnight before reheating.
Why did my chicken turn out dry?
Most likely, the chicken wasn't dry before marinating or was overcooked. Always pat thighs completely dry with paper towels and use a meat thermometer—chicken is done at 165°F. Start checking at 25 minutes of roasting time. The skin-side-up position helps crisp the skin without drying the meat.
What other vegetables pair well with this dish?
This tray bake works beautifully with asparagus, bell peppers, or zucchini. Toss sliced veggies in the same herb-oil mix and add them with the mushrooms. For heartier meals, try brussels sprouts or carrots—just increase roasting time by 5-10 minutes.
