If you have been dubious about “steamed meat” in your thermo mixer, give this recipe a try. This method will lead to a delicious lamb steak combined with fabulous flavour from the pesto.

If you have been listening to the podcast for awhile you will know that Joe has never really found his way to ‘steamed meat’. As a steak lover, even the idea that we did this experiment to make steak in the Thermomix is a bit beyond comprehension. And yet, we can report back… this steak in the Thermomix is quite delicious!

This recipe was featured in Episode 109 of the podcast: Thermomix Lamb Recipes.

We encourage you to give this basil pesto version of steak in the Thermomix a try. Lamb steaks are not the cheapest cut of meat, but we found them to be particularly delicious!

Recipe Tester Feedback: “Yum! Lamb was cooked to perfection and so moist, and the pesto sauce was so flavoursome. We will definitely be cooking this recipe again.” – Christina
