No funny business here, just a good old wholesome family favourite using good-for-you ingredients!

Michael is a self-professed mushroom avoider at all costs, and even HE loved this casserole

Couldn’t get enough. Went back for a hefty portion of seconds. That kind of LOVE.

My mom used to make a somewhat similar recipe when we were growing up, except I think it contained fruit chutney and processed soup powder! Things that I never, ever buy, lol (Nor does she, nowadays).

That said, I have fond memories of its yumminess, so I felt inspired to create something equally moreish with all healthy ingredients.

This chicken casserole is certainly moreish, comforting, filling and nourishing!

How to make one pan Garlic Mushroom Chicken Casserole?

  • Using a large casserole dish (I like metal, but ceramic works too), heat the coconut oil in the oven
  • Toss chicken pieces in flour mixture, then brown in hot oil
  • Add all other ingredients and bake for about an hour until sauce is thick and chicken is cooked through and fall-off-the-bone-tender (see recipe!)
  • Serve with your choice of side (options below)

If you’re looking for a simple, one pan recipe that can be thrown together in 30 minutes, baked in the oven for about an hour, served with a side of rice or quinoa or lentils (or a mix of ALL THREE which is what I did – highly recommend) or creamy mashed potatoes with mixed veggies or a salad…

Talk about versatile, that’s a whole bunch of different side dish options, and this casserole is UTTERLY DIVINE with any of the above!

Sounding GOOD?

THEN THIS RECIPE IS FOR YOU, one-pan-recipe King or Queen! You’ve got this.

  • 3 tbsp coconut oil
  • 1 whole chicken
  • 2 tbsp gluten free flour , heaped
  • 1 tsp Himalayan pink salt
  • 1 tsp ground black pepper
  • 2 tsp Italian herb mix , I use "Simple Truth Italian Rub"
  • 3 onions , sliced into quarters
  • 3 large cloves garlic , finely chopped
  • 250 g button mushrooms , or mushrooms of choice, sliced
  • 1 cup coconut milk
  • 2 cups chicken broth , low sodium
  • 2 tbsp cornflour , dissolved in a little chicken broth
  1. Preheat oven to 250°C (482°F).

  2. In a large casserole dish (I like to use a metal one, but ceramic is fine), heat the coconut oil in the oven for 10 minutes.

  3. Slice chicken into 8 pieces – legs, thighs, breasts (you can slice these in half) and wings, discard back-bone.

  4. In a large bowl, mix the flour, salt, pepper and herbs together. Toss the chicken pieces in the flour. Take the casserole dish out of the oven and carefully toss the chicken pieces in the hot oil (it should simmer), place back in the oven for 10 – 12 minutes or until golden.

  5. Reduce oven temperature to 160°C (320°F).

  6. Stir in onions, garlic, mushrooms, coconut milk, chicken broth, cornflour mixture and any left-over seasoned flour mixture to the casserole and bake in the centre of the oven with the lid on for 45 minutes

  7. Uncover and continue to cook for a further 15 – 20 minutes or until sauce is thick and chicken is golden-brown, cooked through and fall-off-the-bone-tender!

  8. Serve hot with brown rice, lentils or quinoa (or a mixture of all three like I did!) and a side of veggies or salad. ENJOY!
