  • 1 head fresh cauliflower, cup into 1 inch pieces
  • 1 cup water
  • 1 teaspoon garlic pepper (you can also use ground black pepper, if preferred)
  • 1 tablespoon hot sauce (I used Franks Red Hot sauce)
  • 4 ounces cream cheese, at room temperature
  • 1/2 cup half-and-half or heavy cream
  • 1 teaspoon yellow mustard (you can also use mustard powder)
  • 1 cup shredded sharp cheddar cheese
  • Salt to taste


  • Place your cauliflower pieces into a heatproof bowl, Instant Pot safe pan or steam basket.  
  • Add water to inner cooking pot of your Instant Pot.  Place your heatproof bowl or steamer basket onto a trivet and then lower the trivet into your Instant Pot.
  • Secure the lid on your Instant Pot.  Select the 'Pressure Cook' or 'Manual' function and adjust the pressure to High.  Cook for 1 minute.
  • When the timer beeps, let the pressure naturally release for 1 minutes then quick release any remaining pressure.
  • Unlock your Instant Pot lid and carefully remove the trivet. Set aside for now.
  • Carefully pour out the water from the bottom of the Instant Pot. 
  • Once water is removed, select the 'Cancel' buttom to reset the cooking function.  Press the 'Saute' function and stir in hot sauce, cream cheese, half and half, mustard and shredded sharp cheddar cheese, salt and pepper to taste until all contents are melted and combined.
  • Stir in cauliflower until well combined.  
  • Taste and add any additional salt and pepper, where needed.
  • Serve and watch it go in minutes!




  1. You’ll notice this cauliflower mac and cheese recipe is made with a tad bit of hot sauce.  Don’t be scared!  You will hardly be able to taste the hot sauce at all, but it does add a great bit of extra flavor.  I used Frank’s RedHot sauce, but any hot sauce will do.
  2. If you’re interested in making this even more creamy, feel free to add a tad more half and half and sharp cheddar cheese.  
  3. Speaking of shredded cheddar cheese, where possible, try to shred your own as opposed to adding from the bag.  Pre-packaged shredded cheese has added agents to keep it from clumping in the bag.  That can make it harder for the shredded cheese to melt in this cauliflower mac and cheese recipe.  
  4. If you want to add even more flavor, feel free to add other cheeses like blue cheese, Parmesan cheese and so much more!
