Can I Still Make This If I Don’t Have An Instant Pot

If you don’t have an Instant Pot, you can still make a delicious Garlic Parmesan Whole Roasted Cauliflower using your oven. Here’s how:

  1. Preheat Oven: Preheat your oven to 400°F (200°C).

  2. Prepare Cauliflower: Trim the leaves from the cauliflower head and wash it thoroughly. Pat it dry.

  3. Make the Butter Mixture: In a bowl, combine melted butter, minced garlic, grated lemon zest, chopped parsley, salt, and black pepper. Brush this mixture generously over the entire cauliflower head, ensuring it is well coated.

  4. Roast the Cauliflower: Place the cauliflower on a baking sheet lined with parchment paper or in a baking dish. Cover it with aluminum foil to prevent it from drying out. Roast in the preheated oven for about 30-40 minutes.

  5. Add Parmesan and Broil: After 30-40 minutes, remove the aluminum foil. Sprinkle 2 tablespoons of Parmesan cheese over the top and sides of the cauliflower. Return it to the oven and switch to the broil setting. Broil for about 5-10 minutes, or until the cheese is golden brown and crispy.

  6. Serve: Carefully remove the cauliflower from the oven and let it cool slightly before serving. Enjoy your flavorful and tender roasted cauliflower!

This method will give you a similarly delicious result, with the cauliflower being tender on the inside and crispy on the outside, infused with garlic and Parmesan flavors.

Tips & Tricks

  1. Choose Fresh Cauliflower: Select a firm, white cauliflower with tight florets and fresh green leaves. Avoid any with brown spots or soft areas.

  2. Prep Thoroughly: Trim the leaves and the base of the cauliflower so it sits flat. Wash thoroughly and pat dry to ensure the seasoning sticks well.

  3. Even Seasoning: When brushing the butter mixture on the cauliflower, make sure to get into all the nooks and crannies to ensure even flavor distribution.

  4. Adjust Cooking Time: If your cauliflower is larger or smaller than average, you may need to adjust the cooking time. Check for tenderness by piercing the center with a knife.

  5. Crispiness Factor: For extra crispiness, after broiling, you can sprinkle additional Parmesan or even a bit of breadcrumbs on top before broiling again for a few minutes.

  6. Alternative Seasonings: Feel free to experiment with different herbs and spices. Adding thyme, rosemary, or even a bit of smoked paprika can give the dish a unique twist.

  7. Serve with a Sauce: A side of marinara, aioli, or a light lemon butter sauce can complement the flavors of the roasted cauliflower nicely.

  8. Leftover Usage: If you have leftovers, chop the cauliflower and add it to salads, grain bowls, or even pasta dishes for an extra boost of flavor and nutrients.

  9. Make It Vegan: Substitute the butter with olive oil and use a plant-based Parmesan to make this dish vegan-friendly.

  10. Timing for Crispness: If using an Instant Pot, remember to broil the cauliflower in the oven after pressure cooking to get that delicious crispy exterior.

    1. I corrected it. I did originally write this recipe with some Ninja Foodi directions included as well and missed that. 🙂

  1. Yum! Have you ever tried making this with cauliflower florets? I’m wondering if it might be extra delicious if florets were tossed in the seasoning mix before cooking, giving each bite LOTS of seasoned yumminess.

    1. Yes 1 min is all you need to still have a bit of crispness. If you would like a softer end result you can increase the cook time by 1 or 2 minutes.

      1. I suppose it also changes with the size of the head… Gave mine 2 Min tonight and it’s just better than raw :-). Will do 4 next time.
        By the way 3 Min at 400 with the crisper lid on the instapot duo crisp worked perfectly for the cheese crust.

  2. I made this tonight and it was really good (and I don’t consider myself a cauliflower fan). But I think next time I’ll break it into florets to get more of the seasoning/Parmesan on the cauliflower.

  3. I cooked it in my IP for 1 minute as instructed and did a quick release and it was super hard. We had to put it in the microwave for 10 mins to get it edible. Is 1 minute the correct time to cook in the IP?

    1. Hi Amber, Yes 1 minute is the correct time for a still crisp cauliflower. Some folks prefer 0 minutes. Try doing yours for 4 min next time. I would be nervous with much longer. See if 4 minutes hits the spot you like.

      1. Just FYI, 4 minutes was mush. We redid for 2 minutes and it was a little too soft so i think the 1 minute we did previously maybe my IP was not sealed correctly. Will try 1 minute next time with quick release.

  4. perfect 1st recipe to try with my new Instant pot! added it to a bed of rice and mushroom “gravy/rue” and it was a fantastic meal. My husband even had seconds! I too was skeptical about the 1 minute, but I think the time it took to come to pressure added to the cooking time.

    Thank you for making me not so scared of my new toy!

  5. What type of parmesan did everyone use? I’m making mine now; it’s still cooking and I used fresh grated parmesan. Did everyone else use fresh or did you use the dry stuff? If so, how did it turn out? Also, when mine is done I’ll post again and let you know how mine turns out. I’m cooking it for 2 minutes since we like it a little softer.

    1. Yes you can bake in the oven at 400 degrees in a dutch oven, Cover the dutch oven with a lid and bake for 35-45 minutes, until the cauliflower is tender and pierces easily with a skewer, knife or fork.

      Save 2 tablespoons of grated Parmesan cheese to finish it off under the broiler. Place the cauliflower under the broiler and broil for about 5 minutes, until the cheese is browned.
