Ingredients

1 tablespoon olive oil
2 tablespoon salted butter
4 white onions finely sliced
½ teaspoon sugar
4 garlic cloves minced
2 chicken breasts sliced into small pieces
2 tablespoon all-purpose flour
500ml beef stock
200ml white wine stock or 150ml white wine
1 small baguette sliced into 8, 1 inch pieces
80g gruyère cheese grated
10g chives finely sliced

Instructions

Place a casserole dish on medium heat and add in your olive oil followed by the butter. Once melted, add in your sliced onion and fry for 15 minutes, stirring frequently.
Once the onions have caramelised slightly, add in your garlic and sugar. Fry for a few more minutes.
Add in your sliced chicken breast and fry for 5 minutes, season with a sprinkling of salt and grinding of pepper.
Pour in your flour followed by the beef and white wine stock. Give everything a good mix until combined and then simmer for another 10 minutes until the sauce has thickened and the chicken is cooked.
Once the French onion soup chicken casserole stew is viscous and the chicken is cooked through, give it a taste and season accordingly. Feel free to see the step by step images further up this blog for reference!
Top the chicken casserole with sliced baguette and then sprinkle with grated gruyère cheese. Place under the grill for a few minutes until the cheese is melted and golden.
Remove the chicken casserole French onion soup dish from the grill and top with chopped chives. Enjoy!

To double quantity: This recipe can be doubled to make the dish for 4 people. Or you can bulk up this recipe to serve 4 by serving it with pasta or mashed potato.

Storage: Place any leftover French onion chicken casserole in airtight containers once cooled and into the fridge for up to 3 days.

Freezing: To freeze, once again, leave the dish to cool then place it into airtight containers. Don't forget to label the containers. Place into the freezer for up to 3 months. When you're ready to eat it, leave to thaw in the fridge overnight and then follow the reheating instructions below.

Reheating: Leave the container lid slightly ajar and place in the microwave and heat until piping hot. You could alternatively place any casserole leftovers (minus the bread) in a pan and place on medium heat with a splash of water. Heat until simmering, then enjoy with fresh baguette. If you want to reheat your baguette slices, then place them under the grill for a few minutes to heat and crisp up.
