How to Cook the Perfect Roast in a Wood Fired Pizza Oven (Without Burning It)

 

Ever roasted a leg of lamb in your wood-fired oven? If not, you’re seriously missing out.

That crispy skin, juicy meat, and smoky flavour hit differently when it’s done over real hardwood. But mess up your timing or temp and you’ll be carving into burnt edges with a raw centre. Not exactly the hero moment you were hoping for.

Let’s walk through how to master the roast in your wood fired pizza oven so you can impress your guests and enjoy the kind of flavours you just can’t get from your kitchen oven.

Why Wood Fired Roasts Are Worth the Hype

Wood-fired ovens aren’t just for pizzas. When set up right, they deliver steady, radiant heat and unbeatable smoke flavour perfect for roasting lamb, pork, beef, and even chickens.

Here’s what makes a roast in a wood-fired pizza oven so special:

  • Smoky flavour infusion you can’t fake with gas or electric
  • Crispy, caramelised outer layer with juicy meat inside
  • Multi-task cooking (throw in spuds, apples, garlic bread done!)
  • That outdoor cooking vibe your mates won’t stop talking about

Fire It Up: Setting Your Oven Temp the Right Way

The secret to nailing your roast starts before the meat even goes in.

Here’s how to set your oven:

  1. Build your fire using a raised log holder (or a traditional teepee shape).
     
  2. Use natural firelighters, kindling, and seasoned red gum (we love red gum for its long burn and flavour).
     
  3. Leave the oven door and chimney flue wide open for the first 10 minutes this maximises oxygen and gets your fire roaring.
     
  4. Once it’s lit, close the door most of the way (leave a gap) and close the flue halfway to start building internal heat.
     
  5. Target temp: 200 to 220°C ideal for roasting. If you have the time, cooking at a lower temperature for a longer time will give even more epic results.
     

Prepping the Star of the Show: Your Leg of Lamb

The one in our video was a 1.3kg deboned leg of lamb, a great size for feeding the fam or a couple of hungry mates.

Prep steps:

  • Remove the butchers twine so you can season both inside and out.

  • Season generously with Flaming Coals Traditional Lamb Rub, a BBQ favourite that hits every time.

Into the Oven It Goes: Tips for Cooking Evenly

Once your oven's holding a steady 200 to 220°C, pop your lamb into a heavy duty roasting pan. Throw in some garlic cloves, rosemary sprigs, and potatoes for good measure.

Pro Tips:

  • Rotate the pan every 15 to 20 minutes to ensure even cooking.
  • Don’t rely on time alone, always use an instant-read thermometer.
  • Target internal temp: 55°C for medium-rare lamb.

Total cook time? Ours took just over an hour but always trust your thermometer, not the clock.

The Payoff: Crispy Skin, Juicy Centre, Full Flavour

Once you hit that magic internal temp, it’s time to pull it out, rest it, and slice it up. The smell alone will have everyone drooling.

What you’ll get:

  • A crispy outer crust
  • Tender, smoky meat throughout
  • Roast potatoes cooked in lamb juices
  • A backyard hero moment you won’t forget

Quick FAQs

Q: What’s the best wood for a wood-fired roast?
A: We recommend red gum. It burns hot and slow with a clean, smoky flavour that’s perfect for roasting. Just make sure it’s seasoned and dry. Wet wood won’t burn properly and you’ll be kicking yourself for picking up that bag from the petrol station. 

Q: How long does it take to roast lamb in a wood-fired oven?
A: A 1.3kg deboned leg of lamb takes around 1 hour at 200 to 220°C, but always check with a thermometer.

Q: Can I cook other meals in the oven while roasting?
A: Absolutely. Toss in garlic bread, baked apples, or a tray of veg, just rotate and check regularly.
