👪 Why You Should Make Healthy Slow Cooker Chicken Casserole

• Healthy and Lean: This easy chicken casserole uses boneless skinless chicken thigh fillets, making it a lean and nutritious dinner option.
• Versatile: Although I've used carrots, swede and potatoes you can pretty much choose what vegetables you want to add. You could also add any leftover vegetables making it adaptable to what you have lying around.
• Easy and Quick: This is a simple chicken casserole to prepare with only 20 minutes of prep time then a little pre-cooking. Then everything goes into your slow cooker to cook allowing you time to get on with other things.
• Family-Friendly: Tastes great and is customisable therefore suitable for the whole family and their individual tastes.
• Budget-Friendly: Chicken thighs are often a cheaper cost-effective choice compared to chicken breasts. All of the other ingredients shouldn't break the bank with their costs either.

🔪 Step By Step Instructions

Detailed instructions are in the recipe card below. But here is a quick step by step guide of how to make this healthy slow cooker chicken casserole recipe:

Step 1

• Place the cornflour in a bowl and season with some salt and pepper.

Step 2

• Dip each piece of chicken into the seasoned cornflour.

Step 3

• Fry the onion in a large frying pan until softened.

Step 4

• Add the garlic, dried mixed herbs and chicken to the pan and cook until no longer pink and browned slightly.

Step 5

• Scrape the contents of the frying pan and all their juices into your slow cooker.

Step 6

• Add the carrots, swede, potatoes and Worcestershire sauce.

Step 7

• Add the chicken stock. Mix well together.

Step 8

• Cook on low for 3-4 hrs, or on high for 2-3 hrs.

Step 9

• Stir in chopped parsley, season to taste and serve.

📖 Substitutions

• Cornflour - I find cornflour best for thickening the sauce. You could use plain flour instead but it might make the sauce lumpy.
• Freshly Ground Salt and Black Pepper
• Boneless Skinless Chicken Thigh Fillets - it's possible to use an equivalent weight of chopped up chicken breasts but you won't get as much flavour from them.
• Olive Oil - just use cooking olive oil. No need to use expensive extra virgin olive oil here.
• Onion - I use a brown onion but you could also use a red onion.
• Fresh Garlic Cloves - I recommend only using fresh garlic cloves here which are best for flavour rather than garlic granules.
• Dried Mixed Herbs - you could use dried oregano or dried thyme instead or a mixture.
• Carrots - you could choose your own vegetables instead. See suggestions in FAQ's below.
• Swede - you could choose your own vegetables instead. See suggestions in FAQ's below.
• White Potatoes - you could choose your own vegetables instead. See suggestions in FAQ's below.
• Worcestershire Sauce - you can omit completely or you could use soy sauce instead.
• Chicken Stock - it's possible to use vegetable stock instead but chicken stock is best for the complete all round flavour of this recipe.
• Freshly Chopped Parsley (optional garnish).

How Many Calories Are In A Chicken Casserole?

There are 382 calories in this Chicken Casserole recipe.

Why Is This Slow Cooker Chicken Casserole Healthy?

This is a healthy chicken casserole because it uses lean, boneless, skinless chicken thighs, and is low in unhealthy fats, relying on olive oil for its fat content. Additionally, the use of stock, fresh vegetables and herbs add enough flavour without the need for anything else.

What To Serve With?

I usually just serve a little rice alongside this casserole because it is quite filling. A side of steamed green vegetables like broccoli or green beans also goes well as does a simple green side salad.

What Vegetables Can I Use In A Chicken Casserole

Other vegetables that you could use instead of the ones I have suggested, that also work well in this recipe include bell peppers, courgettes, mushrooms, peas, green beans and leeks.

How To Store This Chicken Stew?

This chicken stew can be stored in the fridge in an air-tight container, once cooled, for about 3 days. Or you can freeze the stew. Portion it up and transfer to airtight containers to freeze.
