Cooking process for Chicken Brocolli casserole is really simple. To make this great recipe you need to:

  1. Dice the chicken: Place the raw chicken meat on a clean cutting board. Slice it into strips about ½ inch wide. Then cut them across to make small cubes about ½ inch in size.
  2. Dice the onion: Dice the onion to fine pieces
  3. Set Instant Pot to Sauté: Heat the oil in the Instant Pot on sauté mode. This will help to brown the onions and add flavor to the dish.
  4. Cook Onions: Add the onions and cook until they start to brown. This should take about 2-3 minutes.
  5. Sauté the chicken: Add the chicken and sauté until it gets lightly browned from all sides. You need to cook it through. Add more butter if necessary to avoid sticking.
  6. Scrape the bottom of the pot: Deglaze the bottom of the pot with a small amount of chicken stock. Scrape the bottom enough, so that you loosen any stuck bits.
  7. Add the almond flour: Add the almond flour to the pot. Cook for a minute, whisking constantly.

  12. Add the cheese: Sprinkle shredded Gruyere cheese over the top of the mixture.
  13. Pressure Cook: Close the Instant Pot lid and sealing valve then set to manual – high pressure – for 5 minutes. Just sit back and let the Instant Pot do the work for you.
  14. Quick release: Do a quick release of pressure by carefully turning the pressure release valve to its venting position.
  15. Finish the casserole: Once all the pressure has been released, you can open the pot. Give it a stir and serve. Enjoy!

Mmmm. Yummy.

Want to mix it up? Try using Italian sausage instead of chicken in this recipe. Just substitute cooked and crumbled sausage for the chicken and follow the same instructions. You’ll have a delicious twist on the original!

  • Substitute cauliflower for broccoli: If broccoli isn’t your favorite or you’re looking to switch things up, cauliflower is a great alternative. It’s an easy switch, just follow the same instructions.
  • Looking for a different cheese? Gruyere cheese is great in this recipe, but don’t worry if you don’t have it. Use any shredded cheese you like. Cheddar, smoked gouda, and mozzarella all work very well. Even parmesan cheese is great!
  • Add cooked and crumbled bacon: If you want to take this dish up a notch, try adding some cooked and crumbled bacon. Bacon goes well with keto chicken recipes and adding eight ounces of cooked and crumbled bacon will give this dish an extra punch of flavor.
  • Cauliflower rice: Looking for a low-carb option for rice? Try out adding cauliflower rice. You can either make your own by pulsing cauliflower florets in a food processor or purchase pre-packaged cauliflower rice from the grocery store
  • Cooked chicken or rotisserie chicken: If you have some leftover cooked chicken or if you fancy rotisserie chicken, you can use it too. That will make the whole recipe even quicker and you make a good use of leftovers.

Pro tips

Fresh brocolli
Try to get yourself a fresh broccoli.

Here are a few tips to get you a perfect chicken broccoli casserole every time:

  • Sauté onion and garlic in butter before adding liquids: Before adding liquids, you can sauté ½ cup diced onion and 2 cloves of minced garlic in butter to give the dish an extra punch of flavor.
  • Use fresh broccoli if possible: Fresh broccoli will provide the best taste and texture in this dish. If you don’t have fresh broccoli, frozen broccoli can work too. But let it thaw completely in a large bowl and drain any excess water before using it in the recipe.
  • Buy whole broccoli: When shopping for broccoli for this recipe, it’s best to buy the whole broccoli head rather than just the florets or crowns. The stalks carry a lot of the flavor. You can chop them into smaller pieces. Don’t let them go to waste!
  • Revive limp broccoli: If your broccoli has gone a little limp, don’t throw it away! Trim the bottom of the stalk. Let it stand in a layer of water and refrigerate it overnight. This trick can revive limp broccoli and make it ready to use in this keto casserole.
