What Makes This Instant Pot Cauliflower Recipe Unique
This cauliflower instant pot recipe stands out because it combines speed, flavor, and simplicity—all in one pot. Traditional roasting can take upwards of 45 minutes, and steaming often leaves cauliflower bland. But this method uses pressure to infuse flavor deep into every floret.
You don’t need a steamer basket, oven, or special tools—just the trivet that came with your Instant Pot. As the cauliflower recipe instant pot cooks, the broth picks up flavor from the garlic, onion, and herbs. That same broth then becomes a creamy, blended gravy.
One vegetable, one pot, and one surprisingly satisfying main or side. It’s ideal for holiday spreads, vegan dinner guests, or just a Tuesday night when you want something warm and reliable.

Step-by-Step Instructions for Cauliflower Instant Pot Recipe
This cauliflower instant pot recipe is straightforward, and most of the work happens right inside the pot. Each step is designed to build flavor without extra cleanup.
Step 1: Clean and Prep the Cauliflower
Remove the leaves and trim the stem so the cauliflower sits flat. Soak it in warm salted water for 10 to 15 minutes to loosen any dirt or hidden insects. Rinse well and pat dry.
Step 2: Marinate the Cauliflower
In a small bowl, mix the garlic, thyme, parsley, olive oil, lemon juice, smoked paprika, salt, and pepper. Rub this mixture evenly over the entire head, including the base. Let it rest for 30 to 60 minutes, if you have time.
Step 3: Sauté Aromatics and Add Liquid
Turn on the sauté mode on your Instant Pot. Add olive oil, then the onion and whole garlic cloves. Cook until they’re soft and just starting to brown. Pour in the broth, thyme, and lemon juice. Place the trivet inside the pot.
Step 4: Pressure Cook
Set the cauliflower head on the trivet. Secure the lid, then cook on high pressure for 3 minutes. Allow a natural pressure release for 5 minutes, then switch to quick release.
Step 5: Optional Broil Finish
For a golden crust, transfer the cooked cauliflower to an oven-safe dish and broil on high for 3 to 4 minutes. Watch closely.
Step 6: Make the Gravy
Switch back to sauté mode. Whisk the flour into the broth and onion mixture. Use an immersion blender to blend it smooth, then simmer until thickened—about 3 to 4 minutes. Season to taste.
This cauliflower recipe instant pot method gives you a flavorful, full-texture cauliflower centerpiece—with creamy gravy and no need for extra pots or pans.
Helpful Tips for the Best Cauliflower Instant Pot Recipe
Even a reliable cauliflower instant pot recipe can benefit from a few small refinements. These tips help ensure great texture and flavor every time.
Use fresh herbs and garlic
Fresh thyme and parsley bring brightness that dried versions can’t match. Garlic, when finely chopped, spreads its aroma more evenly.
Marinate for deeper flavor
Give your cauliflower at least 30 minutes to absorb the marinade. The longer it sits, the better this cauliflower recipe instant pot version turns out.
Broil for contrast
A few minutes under the broiler creates a crispy, golden surface that adds visual appeal and texture contrast.
Stick to the timing
Don’t go over the 3-minute cook time. The cauliflower continues to soften during the natural pressure release. Overcooking is the easiest way to lose structure.
Don’t skip the gravy
The gravy adds richness and rounds out the dish. It’s part of what makes this cauliflower instant pot recipe so satisfying.
