Just 10 minutes of prep time and you have a delicious creamy concoction of chicken, celery, and cheese topped with crispy fried onions!
If you think you don’t like casseroles, then you probably just haven’t tried the right one. We have several favorite chicken casseroles, like a chicken crescent roll casserole, chicken and broccoli casserole, and this French onion chicken casserole!
A casserole for even the pickiest eaters
I really don’t like being a picky eater, but I am. Yes, it’s true… I can’t stand onions. They gross me out. BUT, having said that I actually like french fried onions… maybe the fact they’re breaded and fried makes them okay. 😉
This next recipe I’m sharing is topped off with those delicious french fried onions and filled with all sorts of goodness like chicken, cheese, sour cream, mayo and almonds. It is DELICIOUS!
The best thing about this French Onion Chicken Casserole is that it takes little prep time. Literally, it takes minutes to throw together if your chicken is already made. You can buy cooked, chopped chicken, but I like to bake my chicken earlier in the morning.
10 minute prep
Although it takes awhile to bake, it really only takes about 5 minutes of prep work. Add that with the 5 minutes it takes to put this casserole together and you’re looking at about 10 minutes of work.
PREP. Preheat oven to 350 and coat a 9×13 baking dish with cooking spray.
BAKE. In large bowl, stir celery, cheese, sour cream, mayo and cream of chicken. Add chicken and almonds. Spoon into dish. Bake uncovered for 30 minutes.
TOPPING. Sprinkle fried onion and cook another 5 minutes. Let stand 5-10 minutes. Enjoy!
Tips + variations
Here are a few ideas to tweak the recipe to make it a little more healthy:
- Use a low fat Mayo and sour cream
- Substitute all or a portion of the Mayonnaise with a low fat Greek yogurt
- Add veggies—sliced carrots, peas, broccoli florets, and shredded zucchini are all good choices
- Make it even more keto friendly and sprinkle cooked chopped bacon bits on top
- Serve over white or brown rice, pasta, cauliflower rice, or zucchini pasta
Serve French onion chicken casserole with any of the following:
Storing info
To make ahead of time, assemble and cover with plastic wrap and store in the fridge for a day. If freezing, then add another layer of aluminum foil and freeze for 2-3 months. Thaw overnight in the fridge before baking. Do not add the fried onions until the last 5 minutes of baking time.
To STORE, divide the leftovers into single serve portions. Store the portions in airtight containers and keep in the fridge for days. To reheat quickly, use the microwave. If you have a little more time reheat in the oven.
The fried onions may become mushy as it sits in the fridge. To crisp them back up simply stick the casserole under the broiler. Watch carefully as they can go from soggy to burnt really quickly.
