Preheat the oven to 420F / 220C.
In a 14-inch round oven-safe pan, drizzle olive oil and sprinkle with flaky salt.
Add the washed and drained freekeh to the pan and spread it out evenly.
Place the chicken thighs on top of the freekeh. Spread the Roma tomatoes and red onions around the chicken thighs.
Using a tablespoon, spoon the sauce over the chicken thighs and spread it well.
Gently pour in 4 cups of boiling water.
Cover with wet parchment paper and then aluminum foil.
Bake in a preheated oven at 420F for 55 minutes.
Remove the cover and switch the oven to convection broil at 450F for 5–7 minutes, until the top is golden brown.
Garnish with Maldon flaky salt and chopped parsley.
