Golden chicken bathed in a herby brown butter sauce loaded with umami-rich mushrooms - the kind of pan sauce you want to eat with a spoon. But try to resist, because it'll taste even better spooned over creamy Parmesan polenta with green beans alongside. Deeply savoury, quietly impressive.

Produced in a facility that processes eggs, milk, fish, peanuts, sesame, shellfish, soy, tree nuts, and wheat.

  • Roughly flat mushooms. 
  • Trim green beans. 
  • Pick and finely chop rosemary.
  • Cut chicken tenderloin into 1cm strips.
Steam the beans
2
  • Add green beans and a splash of water to a microwave-safe bowl, then cover with a damp paper towel.
  • Microwave green beans on high until just tender, 2-4 minutes.
  • Drain any excess liquid, then season with salt and pepper. Cover to keep warm.
Cook the chicken
3
  • In a large frying pan, heat a drizzle of olive oil over medium-high heat.
  • When oil is hot, cook chicken and oyster and shiitake mushrooms, tossing occasionally, until browned and cooked through, 5-6 minutes. Season generously with salt and pepper. 

TIP: Chicken is cooked through when it's no longer pink inside.

Make it saucy
4
  • To pan with chicken, add Worcestershire sauce, the butter (for the sauce) and rosemary and cook until fragant and beginning to brown, 2-3 minutes.
Cook the polenta
5
  • Meanwhile in a medium saucepan, combine the water, milk and salt and bring to the boil over high heat.
  • Reduce heat to medium and slowly whisk in instant polenta, then cook, stirring, until smooth and thickened, 2-3 minutes.
  • Remove from the heat, add Parmesan cheese, the butter and a good pinch of pepper and stir until melted.
Finish & serve

  • Divide polenta between bowls. Top with wild mushroom brown butter chicken. Spoon over any remaining butter sauce. Serve with green beans. Enjoy!
