🥬 Pressure Cooker Cauliflower Ingredients

Whole head of cauliflower – Leaves removed. You can use purple, orange, or green cauliflower for color variety.

Water – The liquid allows the Instant Pot to build steam pressure, cooking the cauliflower more evenly. For more flavor, replace water with vegetable broth or add a squeeze of lemon juice or fresh herbs to brighten the flavor.

⚙️ How To Cook Cauliflower In The Instant Pot

This is an abbreviated version of the full recipe directions found at the bottom of the post.

1. Prep the cauliflower: Remove any outer leaves and trim the stem so the cauliflower can sit flat on the trivet. Rinse and pat dry.
2. Add water and place the metal trivet on the bottom of the pot. Set the entire head of cauliflower head on top of the trivet.
3. Seal the lid and cook on High Pressure for 2 minutes. The pot will take about 10 minutes to come to pressure before cooking time begins. When the timer goes off, immediately perform a quick release to stop the cooking process and prevent over-softening.
4. Remove and drain: Lift out the trivet carefully and drain any remaining hot water from the pot.
5. Optional browning step: For added texture and flavor, return the cauliflower to the pot on Sauté mode with a drizzle of oil or butter. Brown each side lightly until golden.
6. Serve: Cut into wedges or florets and season to taste with salt, pepper, or your favorite herbs and sauces.

🍽️ How To Season Cauliflower

One of the many wonderful things about cauliflower is that it’s like a blank canvas. You can season your in so many different ways from subtle to super spicy! These are a few of my favorite ways.

• Classic spice blend: Salt, pepper, onion or garlic powder, and maybe a little butter and a sprinkle of Parmesan cheese.
• Garlic & Herb: Olive oil, minced garlic, parsley, fresh thyme and rosemary or Italian seasoning.
• Spicy: Red pepper flakes, cayenne pepper, smoked paprika, or Cajun seasoning.
• Cheesy: Top with melted cheddar or cheese sauce or dust heavily with Parmesan.
• Global twist: Try dusting with curry powder for Indian-inspired flavor or a tahini drizzle and some sesame seeds for a Mediterranean touch.

🧊 How To Store Leftover Cooked Cauliflower

• Let the cauliflower cool completely before refrigerating to avoid condensation.
• Store leftovers in an airtight container in the fridge for up to 4-5 days.
• Reheat in the microwave, on the stovetop, or in the air fryer until warmed through.

❄️ How To Freeze

• Cut into florets, pat dry, and allow cauliflower to cool completely.
• Transfer to a freezer-safe bag and remove as much air as possible to prevent freezer burn.
• Store cauliflower in the freezer for up to 3 months.
• To reheat: Steam or microwave from frozen until hot, or roast for extra crispiness.
