Once you have a clear intention set, grab a notepad, and let's head to the grocery store with our full list of ingredients plus tips to pick the best ones!
Chicken- Organic is best. You can grab some chicken breasts and pre-cook them in the instant pot, slow cooker, or oven and then shred it. Or you can purchase an organic rotisserie chicken from your local health food store or Whole Foods as we did. Just shred it up and add it in!
Fresh Broccoli Florets- Organic is always best to avoid glysophate and pesticides. Just grab a large head of broccoli, wash and chop them up into bite-sized pieces.
Fresh Cauliflower Florets- The same as broccoli- Organic is the best. Be sure to cut it into small pieces. works well in this recipe. (hint: cauliflower can be made into cauliflower rice for a different texture but the same great flavor!)
Fage 5% whole milk yogurt- this specific brand of greek yogurt is a clean brand and its 5% yogurt provides a texture similar to cream cheese. In fact, you can substitute cream cheese in any recipe with this!
Grated Cheese- It is important to go for organic with cheese as well. A lot of shredded cheese has hidden preservatives AND starches, which can throw off a keto diet with sneaky net carbs increase.
The best bet is to buy a block of cheese and grate it yourself. Otherwise, be sure to check the ingredients and nutrition labels of your cheese to ensure clean ingredients and no starch. (hint: potato starch is a commonly used additive in shredded cheese)
Use whatever cheese you prefer, but Mexican Blend, Monterey or Colby Jack cheese, or Sharp Cheddar Cheese all work well!
Buffalo Sauce- Be sure to find sugar-free buffalo sauce like Primal Kitchen.
Chives- Organic Chives can be found in the fresh herb section at any grocery store and serve to be a delicious finishing topping to this cheesy broccoli casserole.
Salt and Black Pepper: Himalayan Pink Salt is the best salt to use as it is not processed like regular table salt and contains all trace minerals needed by the human body.
Plus its taste is second to none! Cracked Black Pepper is a nice finishing touch to season alongside this tasty and nutritious salt.

Add cooked chicken, broccoli, cauliflower, and buffalo sauce to your Instant Pot. Set the pressure cooker setting to high pressure for 1 minute. Quick release the pressure immediately.
Stir in yogurt and half of the cheese until melts slightly.
Scoop into casserole dish.
Broil the casserole for 2-3 minutes until the cheese melts. Garnish with chives. Enjoy!
Hint: The reason we add the cheese and yogurt after the pressure cooker is that the cheese will melt and stick to the bottom of the instant pot.
The IP's self-preservation mode will beep and say food burn. This will not allow the pot to come to pressure and this hiccup may confuse the cooking time! So it's best to add the cheese after releasing the pressure.
Substitutions and Variations
For a vegetarian alternative, consider substituting shredded chicken with tempeh or jackfruit!
For a less spicy alternative, you can adjust the level or buffalo sauce. Be sure to add at least one cup of liquid total to the instant pot in order for it to come to pressure! If you want to lessen the spice, add half a cup of buffalo and half a cup of chicken stock.
If you want to choose a non-buffalo chicken broccoli casserole, swap the buffalo sauce for bone broth, chicken broth, or even almond milk for a creamier flavor. Feel free to add extra seasonings like garlic powder, onion powder, thyme, or rosemary.
The possibilities are endless with the versatility of chicken and broccoli.
If you don't enjoy cauliflower florets, they can easily be substituted for cauliflower rice, wild rice (not keto), spaghetti squash, or zucchini noodles.
For a crispier cauliflower, consider taking an extra step to roast the cauliflower in the oven while the instant pot is going. Add the roasted cauliflower in when you add the cheese and yogurt!
6 or 8 qt Instant Pot
Store your leftover casserole in an airtight container in the refrigerator for up to 4 days.
(Food safety tip: if you purchase a rotisserie chicken please use it right away as waiting with cooked chicken even stored in the fridge will diminish the amount of time the casserole will be good for left over.)
Can also be stored in a freezer-safe container for up to 4 months.
Be sure to follow the times for this recipe well, as overcooking will cause the broccoli and cauliflower to become excessively mushy
While broccoli is not free from carbohydrates, it has a very small amount. A single cup of cooked broccoli has just 2-3 g net carbs. The micronutrients, phytonutrients, and minerals make it a perfect superfood addition to any low-carb recipe or diet!
The carbs in broccoli are non-starchy and paired with healthy fiber and nutrients. The minimal amount of carbs does not need to be counted as the benefits highly outweigh the numbers on the nutrition facts. Many experts believe that eating as much broccoli as you want should not break ketosis if that is your goal.
This depends on the person. Some need 15g of carbs and others can do 30 or even 50g of carbs and under per day to stay in ketosis. This is the general rule that keeps one in a state of ketosis, where the body burns fat for energy instead of carbohydrates.
