Today we’re talking about one of the world’s most well loved dishes, but with a twist: I want to show you how to roast chicken in a steam oven.

A proper roast chicken is something many of us are keen to master. It’s an elusive thing, and one I’ve been working on for years! Because while a roast chicken is not exactly a hard dish to cook, but it’s not so simple to do it really well.

Thankfully, if you’re lucky enough to have the option of using a combi steam oven, you’re already at least halfway to tender, juicy chicken. Today I’ll help you win at this dish by showing you my preferred method of roasting a chicken with minimum fuss, maximum flavour and amazing speed in the steam oven.

Why use a steam oven to roast chicken?

The very thing which makes for delicious chicken skin – high, dry heat – can make the meat underneath, especially the breast, feel a bit like you’re chewing on a piece of cotton wool. I don’t know about you, but bland, dry and tough are not words I want associated with anything I cook, especially not a chicken.

So, what to do? You do still need that high, dry heat, but you also need to retain as much moisture as possible in the chicken as it cooks.

That’s where your steam oven comes in. I have heard veteran steam oven cooks say they’d buy their appliance again just for the way it roasts a chicken, and though I might not go that far, it is a truly fantastic way to make this dish. The browning and crisping of the skin happens on top, while underneath, the moisture in the oven is working to make your chicken meat unbelievably tender.

Because steam cooks chicken faster than conventional dry heat, it hasn’t lost all its juices by the time it’s cooked through and you’ll get dinner on the table faster than you’d expect – steam oven roast chicken takes around 45 minutes for an average sized whole bird, and as little as 30 when you follow the butterflying method I’m talking about today.

Why is it better to butterfly your chicken instead of roasting a whole bird?

To answer this question, we need to talk first about the difficulties of roasting a whole bird.

By design, whole chickens are not things which roast evenly. The darker, fattier leg and thigh meat needs more cooking than the white breast meat, so without careful attention you’re always going to end up with overcooked breast by the time the legs are done. This isn’t helped by the fact that when you roast a chicken traditionally, breast side up, that breast meat sits high and proud in the oven while the thighs are tucked away underneath, getting less direct heat and taking longer to cook.

A steam oven does help keep things moist, but it can’t completely save an overcooked chicken breast while you wait for the legs to be done. There are tricks to overcome this issue, such as roasting the bird upside down for the majority of the cooking time, to protect the breast meat and expose the thighs to more direct heat. That works well, except you’ll have to contend with turning over a searing hot chicken partway through cooking. And you’ll have to do it without damaging any of the precious skin on the breasts, which will be soft and easily torn thanks to all the juices it’s been sitting in.

Another trick is to cover the chicken breast with a protective layer of streaky bacon. The fat in the bacon slowly melts out and bastes the meat during cooking, keeping it moist. It’s not a bad way to roast, but if you don’t actually want the taste of bacon permeating its way through your chicken, it’s not the way to go.

One of the whole-bird techniques I like best is to stuff a generous layer of flavoured butter just under the skin of the breast meat. It gives amazing flavour and the butter moistens and protects the chicken, but it’s fiddly and not something I’m willing to do for a weeknight meal very often.

All those methods above are good and worth both the purchase and effort to cook, but my favourite way to get even cooking is to deconstruct the chicken a bit, removing the backbone and rib cage and flattening the whole thing out. It’s better to roast because this partial deboning and flattening makes the meat more even in thickness, and splays the legs and thighs so they take the bigger hit of direct heat in the oven, slightly protecting the breast meat and making everything cook at about the same time. It might not be as traditional looking as a regular roast chicken, but I will sacrifice looks for taste anytime when the cooking is this easy.

Deboning and butterflying a chicken for roasting

You might think deboning a chicken is hard, but I can promise you it’s not as long as you’ve got a decent (sharp) knife. If you’re really worried about it, though, buy your chicken from a reputable butcher and ask them to take care of it for you. Although I’m comfortable doing the job at home, my local butcher puts my knife skills to shame and doesn’t charge any extra for the privilege of a bird that’s totally ready to season and roast.

If you do want to try deboning the chicken yourself, start by placing it breast side down on a board. Cut through the skin and down one side of the backbone with a sharp knife, then work your way carefully around the ribcage on that side, cutting as close as you can to the bones so you don’t cut away too much meat. When you get to the wing and leg joints, twist each one until the bone pops out, then cut between the joints and the ribcage/carcass. Keep working your way around, lifting the meat and skin away with one hand as you cut with the other, until you’ve cut to the breastbone. Be careful not to cut through the skin, and don’t worry too much if you cut away any small pieces of cartilage or bone as you go – you can trim these off afterwards.

You’ll now have cut away half of the ribcage. Turn the bird around and repeat the whole process from the other side, until you’ve removed the entire rib cage and are left with a large, flat chicken that has only the leg and wing bones attached.

Now that you’ve got a perfectly prepared chicken, it’s time to move on to the recipe.

Steam Oven Roast Chicken

I’ve stuck with the classic seasonings of lemon, garlic and herbs for this steam oven roast chicken, but feel free to mix it up with whatever takes your fancy. The cooking remains much the same regardless of flavourings.
Prep Time15 minutes
Cook Time30 minutes
Total Time45 minutes
Course: Main Course
Cuisine: American
Keyword: Steam Oven Roast Chicken
Servings: 6 people
Calories: 376kcal


  • 3.5 lb whole chicken partially deboned as per the method in post, to give a cooking weight of around 1.5kg/3.3lb
  • 2 whole lemons sliced into 2.5cm (1in) rounds
  • 2 heads garlic halved crosswise (no need to peel or seperate the cloves)
  • 2-3 sprigs rosemary and thyme
  • 3 tbs butter very soft. Olive oil is fine if that's your preference, though butter makes for the most glorious lemony sauce
  • 1.5 tsp flaky salt


  • Preheat oven to 430°F/220°C, combination steam setting. If your oven has variable steam settings, choose 30% (if not, don't worry! Just choose combi steam and the oven will figure out the humidity level for you).
  • Spread the sliced lemons, garlic and herbs over the base of a baking tray (I prefer my lightweight stainless steel pans for quick heat conduction and easy clean-up).
  • Season the flesh of the chicken with just a little salt, then turn it skin side up and lay it over the seasonings in the tray. Tuck in the wing tips and make sure the drumsticks are splayed outwards (see photos).
  • Pat the skin of the chicken dry with paper towel, then dot the entire surface with the soft butter. Season well with salt.
  • Put the tray in the preheated oven until the chicken is cooked through and golden, about 30 minutes. Remove from oven and set aside to rest in a warm place for 5-10 minutes before carving and serving. Discard the seasonings, but keep the precious cooking juices – you can reduce them down and thicken to make a gravy, or (my preference) just serve with the chicken as a buttery lemon-scented sauce.


Time-wise, if your chicken is significantly smaller or larger than the weight I’ve given, adjust your cooking time down or up to suit. The easiest way to tell if it’s done is with a probe thermometer – a good instant-read thermometer is invaluable, especially if your steam oven doesn’t have a meat probe accessory. The cooked temperature should read 74-75°C (164-167°F) in the thickest part of the thigh joint. Make sure the probe is touching meat, not bone, as that’ll throw off your reading.

    Worked beautifully. My only variances were added vegetables, in the last 10 minutes and then I left them there, once the chicken was out and resting. Thank you for recipe. Am also very new to steam cooking.

    I just loved this recipe. As a steam oven newbie it was fantastic and easy to follow. Definitely on our regular dinner menu from now on

  3. I’m not quite sure what you mean by back grill and steam – is that the rear and top elements plus steam? If so it should work fine, but otherwise you could always steam first and grill to finish and crisp the skin of your chicken.

  4. Unfortunately my oven does either steam or bake not both together, I can only get back grill and steam, would that work do you think? Thank you.

  5. You can absolutely just spatchcock it, but it will take less time to cook if you remove the bones – if you’re leaving bones in just be aware that you’ll have to bump up your time somewhat.

  6. Why can’t I just spatchcock the chicken? Why do I need to remove the bones?

  7. I think my oven is really different to yours or my chicken was smaller but after 20 minutes the top was getting super dark but the thicker meat was only at 40 degrees. So I think 220 is way too hot for my specific oven. I will have to experiment!

    I’ve varied this recipe a number of times using the lemon garlic recipe for temps and timing. This works so well and produces a succulent bird in no time at all due to the butterflying of the chicken and the short cook time leaves a moist flavourful chicken with a nice golden crispy skin. I must admit the first time I tried the recipe I doubted the short cook time but the chicken came out great, note. bigger chickens will take a bit longer but are still very quick to cook.

    My favourite go to recipe. I do two chickens if we have guests.
