Quick Chicken Casserole in the Ninja Foodi – Step By Step

Making a chicken casserole in the Ninja Foodi is quick to prepare and tastes delicious. You can make a complete meal in one pot which can be ready in less than 45 minutes (using the pressure cooker function).

And once you set it off, you can go off and do something else, leaving the Foodi to do its thing.

It’s possible to convert pretty much any recipe and make it in a Ninja Foodi (or any multi-cooker). Recently we’ve been using the pressure cooker function on the Foodi for making lots of stews and casseroles, especially on those days when I forget to set the slow cooker off!

🛒 What You Need

Ingredients for Ninja Foodi Chicken Casserole
  • Chicken – use either boneless chicken thighs, or chicken breast.
  • Oil or butter – for sautéing the onions and garlic
  • Onions and garlic
  • Herbs – I used 2 tsp dried mixed herbs and 2 bay leaves
  • Vegetables – use your favourite vegetables, or whatever is available. For this one I used carrots, new potatoes, celery and peas (the peas got added at the end).
  • Stock – make sure you use enough stock for your electric pressure cooker. I added 800ml of chicken stock. I prefer to add hot stock as it helps the Foodi to reach pressure sooner.
  • Cornflour or chicken gravy granules – this is stirred in at the end to thicken up the casserole. I prefer to add a couple of tablespoons of gravy granules, but use what you prefer.
  • Electric Pressure Cooker – I have made this recipe in the MAX 9-in-1 Foodi, 15-in-1 Ninja Foodi and an Instant Pot, but you can use any Ninja Foodi, or, other electric pressure cooker.

👩‍🍳 Cooking A Chicken Casserole In A Ninja Foodi – Step by Step

This recipe gives instructions for cooking a chicken casserole using the pressure cooker function. It can also be made using the slow cooker function on the Ninja Foodi, but follow my slow cooker chicken casserole recipe for that method.


Add a little oil or butter to the Ninja Foodi bowl and switch on to ‘sear/sauté.’ Add the onions and gently cook for a few minutes, until they begin to soften up.

Keeping the sauté/sear function on, add the chicken. I like to keep the chicken whole and then break it apart at the end, I prefer the texture, plus it’s less preparation 😉


Switch the sauté/sear function off and add the remaining ingredients, apart from anything like broccoli, peas or cabbage.

If you are including new potatoes, add these now.


Add the hot stock. I used 800ml of chicken stock, use enough to cover everything in the pressure cooker, while still not going over the maximum line.


Put the pressure cooker lid on and set the valve to ‘seal.’ Switch the function to pressure cooker and set it to high for 10 minutes.

It should take around 10 minutes to reach pressure (the silver bit in the valve will come up when it is at pressure and the timer will start).

Once the timer has finished, I tend to leave it for up to 10 minutes to naturally release before doing a quick release.


Remove the lid from the pressure cooker and gently pull the chicken apart into chunks. The chicken may shred a little and become more like pulled chicken. You can also remove the bay leaves at this stage.

This is also when I add in any extra vegetables that I want to such as frozen peas, broccoli, cabbage. Switch the function on your multi cooker to the sear/sauté mode.

I also take this opportunity to add my choice of thickener, so for me, some chicken gravy granules. Just add 1 tablespoon at a time and stir until it is at your preferred consistency.

Give it a taste test and add any seasoning if needed. Serve and enjoy!

⭐ Ninja Foodi Chicken Casserole Tips

  • Brown Your Chicken First: Use the ‘Sauté’ function to brown the chicken pieces before pressure cooking. This will add a depth of flavour to the casserole that you don’t get from pressure cooking alone.
  • Deglaze the Pot: After browning the chicken, pour in a little stock or wine to deglaze the pot, using a wooden spoon to scrape up any tasty bits stuck to the bottom. This step adds flavour and prevents a ‘burn’ warning.
  • Don’t Overfill: Be careful not to fill the Ninja Foodi more than two-thirds full, as recommended for pressure cooking.
  • Seal Properly: Ensure the valve is set to ‘seal’ when you start the pressure cooking process.
  • Liquid is Key: Make sure there is enough liquid in the casserole for the pressure cooker to work effectively. A minimum of around 250ml of liquid is generally recommended for the Ninja Foodi to be able to pressurise. I used 800ml of chicken stock so there was plenty of sauce to serve with the casserole.
  • Timing is Everything: Pressure cookers cook much faster than conventional methods, but recipes will often require natural pressure release (NPR) for meats to remain tender. Make sure to account for this time when planning your meal.
  • Thicken After Pressure Cooking: If you want a thicker sauce for your casserole, remove the cooked chicken and vegetables after pressure cooking, set the Foodi to ‘Sauté’, and simmer the sauce with a cornflour slurry (cornflour mixed with cold water) until it reaches your desired consistency. Alternatively, stir in some chicken gravy granules.

Ninja Foodi Chicken Casserole

Yield: 4 Servings
Prep Time: 10 minutes
Cook Time: 10 minutes
Additional Time: 20 minutes
Total Time: 40 minutes

Ninja Foodi Chicken Casserole is quick and easy to prepare - once it is all in the pot just leave the pressure cooker to work its magic!


  • 1 tbsp olive oil
  • 1 onion, chopped
  • 2 cloves garlic, crushed
  • 4 chicken breasts/boneless chicken thighs
  • 2 tsp dried mixed herbs
  • 2 bay leaves
  • 4 medium carrots, chopped
  • 2 stalks of celery, chopped
  • 600g new potatoes
  • 300g frozen peas (or broccoli, cabbage etc)
  • 800 ml chicken or vegetable stock
  • 2 -3 tbsp chicken gravy granules to thicken


  1. Switch the Ninja Foodi on and select the 'sear/sauté' function. Add the oil (you can also use butter) and leave to heat before adding the chopped onions. Cook the onions for a few minutes, or until they are starting to soften.
  2. Leaving the sauté/sear function on, add the chicken breasts/thighs and quickly seal on each side.
  3. Switch the sauté/sear function off and add the remaining ingredients, apart from ingredients that don't take long to cook like peas, broccoli and cabbage.
  4. Place the pressure cooker lid on the Ninja Foodi and set the valve to 'seal'. Choose the pressure cooker function and set it to high, 10 minutes. The Ninja Foodi should take about 10 minutes to come to pressure.
  5. At the end of the 10 minutes cooking time, leave the Ninja Foodi for about 10 minutes to release naturally before doing a quick release.
  6. Remove the lid and switch the function to sear/sauté again. Stir in any green vegetables (peas, broccoli etc). Also, add in your thickener of choice; either cornflour or chicken gravy granules and stir. Leave to simmer for about 3 to 5 minutes, or until any green vegetables have cooked through.
  7. If you have not already included potatoes in the pot, serve with rice or mashed potatoes.


  • Add the peas at the end or they will end up overcooked. The same applies to other green vegetables such as broccoli and cabbage.
  • Instead of using gravy granules to thicken the casserole at the end, you can use cornflour instead.

Hi just a quick question. If you double the quantities,do you need to pressure cook for longer? I have made this loads of times and it is delicious but need to feed more people

My ninja foodi doesn't have either a saute/sear or pressure cooker function. Only bought in July.

I made this recipe for my family tonight and it was a big hit . Thanks for sharing such a great recipe. My kids loved it too :-)

Thank you!! I was honestly about to give up with my 9 in 1 and put it on eBay, I've been so disappointed with everything I've made so far, lots of books/blogs appear to have been converted to UK measurements and due to that they dont really work, I tried this as a kind of last attempt and it was fantastic!! Really simple, clear, easy to follow instructions & the resulting dish was delicious, so ok, you've got me hooked -off to make another one of your recipes tonight! If you bring out a cook book please let me know, I'd definitely buy it :)
