• Medium Yellow Onion – Diced into larger chunks for added depth and flavor.
• Yellow or Red Potatoes – Washed and cut into small pieces to cook evenly and absorb all the delicious flavors.

How to Make Instant Pot Cauliflower “Roast”

This cozy, flavor-packed cauliflower roast comes together effortlessly in the Instant Pot! If you don’t have a pressure cooker, don’t worry—you can also make this in a slow cooker (just adjust the cooking time accordingly).

Step 1: Prep Your Veggies

• Start by washing all your vegetables.
• Trim the outer stems off the cauliflower, but be sure to leave the head intact so it holds together while cooking.
• Dice your potatoes and onion into bite-sized pieces and set them aside.

Step 2: Set Up the Instant Pot

• Place the trivet inside the Instant Pot’s inner liner and pour in the vegetable broth.
• Carefully place the whole head of cauliflower on top of the trivet.
• Surround the cauliflower with the diced potatoes, baby carrots, and onion pieces, layering them evenly around the pot.

Step 3: Season & Cook

• Sprinkle the vegan ranch mix and brown gravy mix over the vegetables and cauliflower, letting the seasonings coat everything.
• Secure the Instant Pot lid and set it to Manual High Pressure for 20 minutes.
• Once the cooking time is up, let the Instant Pot naturally release pressure for 5 minutes, then carefully do a manual release.

Step 4: Serve & Enjoy!

• Once all the pressure has been released, carefully open the lid and let everything sit for about 5 minutes to cool.
• Gently transfer the cauliflower and veggies to a serving platter, spooning over any extra broth for extra flavor.

That’s it! You now have a tender, savory, and perfectly seasoned cauliflower roast that’s vegan, gluten-free, and bursting with flavor. Serve it as a main dish or a hearty side—either way, it’s guaranteed to be a crowd-pleaser. Enjoy!
