Equipment

  • Instant Pot (6-quart or larger)
  • Steamer basket or trivet (optional but helpful)
  • Chef’s knife
  • Cutting board
  • Measuring cups and spoons.
  • Immersion blender or food processor
  • Silicone spatula

Ingredients
  

  • 1 large head cauliflower about 2 to 2½ pounds, cut into florets
  • 1 cup water or vegetable broth
  • 3 tablespoons unsalted butter
  • 2 –3 cloves garlic minced
  • ¼ cup heavy cream or half-and-half
  • ½ teaspoon salt plus more to taste
  • ¼ teaspoon freshly ground black pepper

Optional Ingredients (For Flavor Boosts)

  • ¼ cup grated Parmesan cheese
  • 1 tablespoon cream cheese
  • 1 tablespoon olive oil
  • Fresh chives or parsley finely chopped
  • Roasted garlic instead of raw garlic

Instructions
 

Step 1: Prep the Cauliflower

  • Cut the cauliflower into evenly sized florets. You want them similar in size so they cook at the same rate—no crunchy surprises hiding in the mash.

Step 2: Set Up the Instant Pot

  • Pour the water or broth into the Instant Pot. Add the cauliflower directly into the pot or place it on a steamer basket if you want to reduce excess moisture.

Step 3: Pressure Cook to Tender Perfection

  • Seal the lid, set the Instant Pot to Manual / Pressure Cook (High) for 8 minutes, then let it naturally release for 5 minutes before carefully venting. The cauliflower should be fork-tender and fragrant.

Step 4: Drain Well (This Matters!)

  • Drain the cauliflower thoroughly. This is the secret to avoiding watery mash—give it a minute or two to let excess steam escape.

Step 5: Add the Flavor Makers

  • Return the cauliflower to the pot (or a mixing bowl). Add butter, garlic, cream, salt, and pepper. The heat from the cauliflower will gently melt the butter, releasing that irresistible aroma.

Step 6: Blend Until Dreamy

  • Use an immersion blender or food processor to blend until smooth. Taste and adjust seasoning. Add optional ingredients here if using.

Step 7: Serve Warm and Creamy

  • Spoon into a serving bowl, add a pat of butter on top, and inhale deeply. That smell? That’s comfort.
