Ingredients

  • chicken breasts – cut into bite-sized pieces.
  • potatoes – we recommend using white potatoes or Yukon gold potatoes. They are creamy and the shape holds up well during the baking process.
  • broccoli florets – this adds color and nutrition to the dish. You can substitute cauliflower instead.
  • garlic cloves – freshly minced garlic infuses the casserole with a subtle earthiness. You can also use garlic powder in a pinch.
  • sour cream – brings a comforting, creamy element. You could substitute unflavored Greek yogurt also.
  • mayo – we always use our homemade mayonnaise!
  • fine sea salt – this is important to bring out the flavors in your ingredients. Never forget the salt!
  • black pepper – the pungent taste of pepper helps to balance the creaminess in the recipe.
  • shredded cheese – use cheddar cheese, parmesan, marble cheese, or a combination of all of them.

Equipment

  • sharp knife and cutting board – for mincing the garlic, chopping the potatoes, broccoli, and chicken.
  • box grater – for shredding the cheese.
  • large mixing bowl – to stir everything together.
  • casserole dish – we use an 8 x 11 ceramic baking pan.

Instructions

First, start by preheating the oven to 375 and greasing the casserole dish with olive oil or a bit of butter. Set the dish aside.

Step 2

Next, add the chicken pieces to a large mixing bowl and season it with salt and pepper.

Expert tip

Use a meat thermometer to check the temperature of your chicken to ensure it is properly cooked. It should read at least 165.

Recipe variations

  • Spin this dish into a ‘loaded chicken‘ casserole by sprinkling cooked bacon and chopped green onions on top after baking. You can also mix in some ranch dressing or seasoning before baking for a tangy twist.
  • Spice things up by adding curry powder or garam masala to the casserole. You can also add a touch of coconut milk for a creamy and fragrant twist.
  • Replace the potatoes with cauliflower florets to make the casserole lower in carbohydrates. This is a great option for those following a low-carb or keto diet.

Serving suggestions

  • Serve this casserole as a main dish alongside a green salad and some crusty multigrain bread.
  • Roasted vegetables like carrots, Brussels sprouts, or sweet potatoes can be a delicious and flavorful accompaniment to the casserole.
  • Serve the casserole with a side of cooked brown rice or quinoa to make the meal more filling and to soak up any extra sauce.

FAQS

Can I make this casserole ahead of time?

Yes, you can assemble the casserole ahead of time and refrigerate it before baking. Keep it covered with plastic wrap or aluminum foil until you are ready to bake it.

Can I use leftover rotisserie chicken for the casserole?

Yes, using leftover rotisserie chicken is a quick and convenient shortcut. Simply chop the cooked chicken into bite-sized cubes and follow the recipe as directed.

Storage tips

Store any leftovers in an airtight container in the fridge. When properly stored it can last 2-3 days in the refrigerator. Simply reheat in the oven or microwave.

We don’t recommend freezing this dish as the texture of the sour cream sauce can become grainy and separated after thawing.

  1. I think next time I will boil the potatoes first and maybe mash them. The cut up pieces were still pretty hard. I added some cream of chicken as well and a lot more cheese. It needs something like breadcrumbs.

  2. Can I make this with rice instead of the potatoes? I tried it with potatoes and they never cook enough

    1. I’m sorry you haven’t had luck using potatoes. I cut them into pretty small bite-sized pieces and that works for me. I haven’t tested this recipe using rice but I think it might have to be cooked first. I’m not sure there is enough liquid for the rice to cook.

  4. 5 stars
    This was creamy, cheesy and filling but not too heavy. It is a great way to get some veggies in. Will be a regular in rotation!

      1. I like to have a bit of of browned top and I didn’t find that the cheese was burned. If you prefer the cheese more gooey then you could totally add it later or maybe cover the dish with foil while cooking.

  5. 5 stars
    This is a chicken casserole recipe that I’ll make over and over. It’s not only easy to make but taste delicious. Even my picky eater didn’t pick out the broccoli. Yum!

  6. 5 stars
    I loved that this didn’t have any canned soup in it!! So I gave it a go and it was so easy to make and so delicious.
    I did add the crispy bacon to the top like you suggest (But not green onion as I don’t like the taste)
    It was a massive hit with the whole family!!
    My eldest son was at hockey training so couldn’t eat with the rest of us, but he eated up the leftovers and said it was really good!
    Thank you for a great family friendly recipe 🙂

    1. The sour cream/mayo mixture in mine came out “grainy” instead of creamy. What did I do wrong? It still tasted good, but I think it could be better.

      1. There is a couple reasons that could happen: Cold ingredients can cause the fats to separate and form a grainy texture – using room temperature ingredients could help. Maybe your sour cream or mayo is clos to the expiry date? That could also effect the texture. Glad it still tasted good regardless. 🙂
