super simple perfect weeknight dinner chicken casserole

Jump to Recipe
Colorful, creamy and simply delicious. This super simple perfect weeknight dinner chicken casserole, is the perfect dinner for people who want a flavor but still simple dinner.
I really love this oven bake. It is so colorful, it tastes bomb and everyone love it. The kids can’t get enough of this, so safe to say this is kids friendly. It's super simple because you are basically tossing everything in a pan for a few minutes and then in an oven baking sheet, the oven does the rest.
Why is this the perfect weeknight dinner?
- You can prepare everything in the morning and when you come home, just turn on the oven.
- It is the perfect leftover meal.
- You can freeze it and easily put it in the oven. It will taste incredible. The mushrooms won’t have a different consistency. It will taste the same.
- Thanks to the bell pepper you are getting enough vitamin c for the rest of the week.

Ingredients for the super simple perfect weeknight chicken casserole
Bell pepper.
1 red, 1 yellow and 1 green bell pepper. If you don’t like or have one of this color, use your favorite one. You can of course add more bell pepper if you like.Chicken breast.
Sliced chicken breast will be totally fine. The chicken is not the main character in this recipe.Mushrooms.
Brown or white mushrooms.Cream.
If you have access to Italian heavy cream, I would definitely recommend to use this.Tomato paste.
For the perfect color and taste, of course. The tomato won’t dominate here, together with the cream, it will create an unbelievably delicious sauce.Cilantro.
If you cooked my recipes before, you will know that I use it in so many recipes.It is unbeatable if you want a unique and strong flavor in your dish. Don’t worry if you don’t like the taste of fresh cilantro (me neither) you can easily remove the cilantro after cooking.Parsley.
1 handful fresh chopped parsley.Cheese.
200g Gouda cheese. Of course you can add more cheese, there is never too much cheese in a casserole right? If you don’t have gouda cheese, replace it with Emmentaler, mozzarella or white cheddar.Onion.
2 onions or one big onion. Red and white both work really well in this recipe.Garlic.
2 mashed garlic cloves.If you’re a garlic lover you can add one extra garlic clove, for that delicious tasteSpinach.
200g spinach.You know we need some vitamins with all that cheese and heavy cream, haha.Im just joking, but we definitely need something green, as I like my dishes very colorful.Spinach works really good. You can read more about the superfood here
Vegetarian version
I have made the vegetarian version several times, it is as delicious as the one with chicken. You just simply leave the chicken out. I like to add 100g more mushrooms and 2 more bell peppers. But you don’t need to.
