Stir well, then add chicken, sausages and bacon (including all liquid).
When you see bubbles across most of the surface, stir well once more. Ensure all rice is submerged, cover with lid, and transfer to oven.
Bake 20 minutes. Remove lid and check rice by eating a few grains (careful, very hot!) If the rice is just about done, go to next step. If rice grains are still firm in the centre, continue to cook, checking rice every 5 mins - most ovens take about 30 mins total cooking.
Add prawns/shrimp and green onions, QUICKLY (but gently!) stir through, cover with lid, and return to oven for just 3 minutes (just to heat prawns).
Remove from oven, stir gently to fluff, then serve, garnished with more green onions if desired.
Notes
This Jambalaya is started on the stove then finished in the oven—easier than traditional stovetop cooking and gives perfectly fluffy rice every time!
