This chicken broccoli potato casserole tastes delicious with a creamy cheese sauce and crunchy topping. Prepare the chicken and potatoes ahead of time and use frozen broccoli to make this meal come together quickly.
My mother used to make a chicken broccoli casserole regularly for my siblings and I when I was younger, and I just loved it. Then when I was married with a family of my own, my sister-in-law said she added potatoes and a creamy sauce on top that varied from what my mom did.
I took both of these recipes and created a chicken broccoli potato casserole that is creamy and delicious.
You can also make an extra chicken broccoli potato casserole and freeze it for later. Head over here to get tips on how to freeze casseroles.
TIME-SAVING TIPS:
Since I know that making dinner can take time, there are a few things I do in advance to make this casserole faster and easier to get in the oven.
Preparing the Broccoli:
I used to always steam fresh broccoli for this recipe, but now to go faster, especially on busy days, I use frozen broccoli from a bag. If you want, you can still steam fresh broccoli, but if you don’t have time, then bagged broccoli it is.
Preparing the Chicken:
I always keep cooked, shredded chicken in the freezer that can be pulled out and thawed in the fridge or microwave. This tip helps me a lot to get dinner on the table faster.
What I do is cook chicken in the crock pot or Instant Pot, shred it, then place it into individual re-sealable bags and put it in the freezer. Head over here for more info about preparing chicken in advance.
Preparing the Potatoes:
I also cook, peel and slice the potatoes in advance and place them in the fridge or freezer so it’s easy to thaw and add to the recipe.
Sometimes when I know I’ll be making this homemade chicken and broccoli casserole for dinner, I’ll also plan another dinner with potatoes. So on the day I am cooking potatoes for a dinner, (for instance, if I’m making potatoes with chili on top), I’ll always cook extra potatoes that I can place in the fridge or freezer that will be used later for the casserole.
Now that you know my time-saving tips to make this easy chicken broccoli casserole, here are some answers to questions people have had.
