What do you need for Creamy Chicken, Leek and Bacon Casserole
To prepare this chicken and leek casserole, you require the following ingredients. You can find the correct quantities in the recipe card at the bottom of the blog:
- Bacon: Gives a salty bite. Use bacon bits or slice bacon in strips.
- You can also replace them with fried mushrooms or extra sun-dried tomatoes.
- Chicken breast: For this recipe, I used chicken breast. But chicken breast fillets are, of course, also possible.
- Herb compound butter: Butter combined with herbs, garlic, and salt to give it extra flavor.
- This easy garlic herb compound butter is easy to prepare and flavorful.
- Butter and Flour: The basis for the roux. You fry the flour in the melted butter. Do this for at least two minutes; otherwise, the sauce tastes like flour.
- Parsley: Gives a bit of freshness.
- Leeks: This vegetable has a sweet and mild taste. Slice the leek very thinly.
- Cut the leek lengthwise once, up to ½ inch (1 ½ cm) from the bottom. Turn a quarter turn and make another vertical cut to about ½ inch (1 ½ cm) from the bottom. Remove the outer leaves from the leek and wash the leek under running water. You can now wash the sand out thoroughly.
- Baguettes: Crispy bread, with a soft inside. It’s French bread.
- Homemade baguettes are easy and budget friendly to prepare. Here you can find an easy baguette recipe.
- Grated cheese: Use grated Gouda or Cheddar cheese. It melts good.
Add to a warm roux (butter-flour mixture), cold liquid. Add to a cold roux, warm liquid. That way you won't get clumps. When you add the warm liquid to a warm roux, you will get clumps!
