I’m not a picky eater, but I am a particular eater.

I enjoy fruit and chocolate, but never together (which is how thesecoconut butter dipped strawberries came to be).

I lovepoached eggs, but not super runny yolks. If you eat breakfast with me, I’ll always clarify to the server, “medium poached, like I don’t want yellow oozing everywhere when you I poke it with a fork.” I know some of you are shaking your head and saying, “but that’s the best part!

Hot coffee, never iced. Even when it’s 89 degrees at 7:00 am, and the humidity is already at 65%. To me, it doesn’t have as much flavor, aNd I can’t drink it as fast.

And cheese.Except don’t build me a cold sandwich with a cold piece of cheese. I will pick it off every single time, and have done sosince I was a child. But this only applies to sandwiches.

Now warm, melted cheese… that’s where my true love resides. Injust about every application, such as Hot Buffalo Cauliflower Dip…. but especially savoryfontina cheese sauce that sinks into SMOKINGhot whole roasted cauliflower.

With edges charred and browned, dried herbs mixed with olive oil and a little dijon mustard giving it a crust that most with associate with meat.

This is the kind of dish that wins friends. Both those who love vegetables, and those who might be convinced to try only because of the cheese.

The Secret to the Best Whole Roasted Cauliflower

I learned from Joy The Baker that simmering the whole head of cauliflower (basically poaching) in a “brine” before roasted partially cooks the cauliflower, so that it is cooked from the inside out. For the brine,

I used (peppercorns, olive oil, garlic, bay leaves) infuses them with initial flavor all the way through.

Now that the cauliflower is partially cooked, roasting will take care of the crispy edges, turn the core tender, and impart delicious. It’s so tender it nearly melts in your mouth.

Making Gluten-Free Cheese Sauce

When makingcheese sauces, I like using fontina (made from cow’s milk) because it melts like a gem and is extremelyversatile.Roth Cheese, from my neighbor state, Wisconsin, produce a Swedish-style Fontina. The smooth, creamy body accents the slightly tart flavor and mild, yeasty finish.

This sauce recipe evolved from the rosemary bechamel I used on cauliflower steaks at a recent dinner party, and couldn’t have been more perfect for this whole roasted version. To make it gluten-free, you’ll use brown rice flour to make the roux.

Savory. Rich. A golden, crackly masterpiece. Comfort feelings reminiscent of those I had when eating deep fried cauliflower and cheddar cheese sauce at the local watering hole with my parents when I was young. Except it’s a little more refined, quite impressive to serve, and wholesome,real food magic. Enjoy, xo.

SCALE:

Ingredients

Cauliflower

  • 1 tablespoon kosher salt
  • 2 teaspoons black peppercorns
  • 1 head of garlic smashed
  • 1/2 lemon
  • 1 bay leaf
  • 2 tablespoons olive oil
  • 1 medium head of cauliflower leave removed and core cut off a bit on the bottom so it sits flat

Cauliflower Crust

  • 2 tablespoons olive oil
  • 1/2 tablespoon dried parsley (or oregano)
  • 1/4 teaspoon garlic powder
  • 1 teaspoon dijion mustard
  • 1/2 teaspoon kosher salt

Fontina Cheese Sauce

  • 2 tablespoons butter
  • 2 tablespoons brown rice flour
  • 2/3 cup heavy cream
  • 2 1/2 cups two percent milk
  • 2 1/2 ounces Roth fontina cheese shredded
  • 1/4 teaspoon sea salt
  • 2 teaspoons minced fresh rosemary
  • 1 tablespoon minced fresh parsley
  • grated fresh nutmeg

Instructions

  • Preheat oven to 450 degrees F.

  • Bring large pot of water (I use a 5 quart dutch oven and fill it about 5 inches to the top. You’re looking to give the cauliflower room to float) to boiling. Stir in all of cauliflower ingredients, then put in cauliflower, core side facing the ceiling (so top of head down). Simmer for 15 minutes, until cauliflower is fork tender.

  • Drain cauliflower, and carefully place it on parchment lined sheet pan. Whisk crust ingredients together and brush all over cauliflower crust (if your cauliflower is really large, use an extra tablespoon of oil when mixing the ingredients up). Bake for 40 minutes, until crust is charred and brown. You can broil for a few minutes at end to really get crispy edges.

  • Meanwhile, heat butter in a saucepan on medium to melt. Whisk in flour, and cook for 2 to 3 minutes, stirring constantly, so flour can get heated through. Then whisk in cream and milk, until smooth. Add salt and bring to a boil, then turn down to simmer. Cook for 10-12 minutes, until sauce starts to thicken.

  • Add shredded cheese and whisk, until melted. Cook for one minute, than add rosemary, parsley and a few gratings of fresh nutmeg. Taste, and add a little salt if needed.

  • Pour over warm cauliflower, and reserve some for dipping.

FAQs

Why do you soak cauliflower before cooking? ›

If you're planning to roast the cauliflower whole or slice it into steaks, slice off the thick stem at the base. Drop the whole cauliflower head upside-down into cool, salted water. Let it soak for 10 to 15 minutes to remove dirt, residue and bugs.

Why does my cauliflower cheese sauce go watery? ›

Cauliflower cheese can go watery if the cauliflower is overcooked. Overcooked cauliflower releases water, which will seep into the rest of the dish. So even if your sauce was thick when it went in the oven, if its in there too long, the water from the cauliflower will cause it to go watery.

Why is my roasted cauliflower tough? ›

Have you roasted cauliflower before and it came out tough or mushy? A common problem is either roasting it at too low a temperature or stopping once the cauliflower is tender—both mean that the florets do not caramelize.

Why is my cauliflower au gratin watery? ›

The dish may get watery if the cauliflower is overcooked – that's when the florets release more water – or if you haven't drained the florets well after steaming/boiling them. Make sure the florets are properly drained and that you stick to the exact instructions from the recipe.

Should cauliflower be washed before roasting? ›

The separated florets have to be washed properly under a tap. This removes dirt and large parasites such as worms. The next step is cleaning the cauliflower in mildly warm water in which a little salt was dissolved. This process – which should last 10-20 minutes - destroys several microbes and large parasites.

What does baking soda do to cauliflower? ›

Baking soda is often used as a natural cleaning agent, and it can be used to brighten up your veggies too. Sprinkle a little in the water before boiling to prevent cauliflower from yellowing and make corn look more vibrant.

Why is my cauliflower not getting crispy? ›

Like all veggies, cauliflower needs some breathing room on the pan. Otherwise, the florets will produce so much steam that they'll never turn crisp on the edges. It's better to use two pans, arranged on separate racks near the middle of the oven, than to cram too much onto one pan.

Why is my cauliflower cheese hard? ›

Baking it, I find, has a tendency to overcook the cauliflower before the top browns. Adding the cheese sauce hot means there's no need for any further baking – the top will bubble and brown in minutes, before the cauliflower has time to soften any further.

How do you squeeze moisture out of cauliflower? ›

Transfer the riced cauliflower to the center of a clean dish towel. Arrange the towel filled with cauliflower over a small bowl, then squeeze as much liquid as you can out of the cooked cauliflower. It might not feel like there's excess moisture at first, but you may be surprised by how much liquid is released!

How do you keep cauliflower from getting mushy? ›

The key to nonmushy cauliflower lies in how you cut it: Break apart the large head into smaller florets. Now take your knife, and starting at the stem end of the floret, slice about halfway down and snap apart.

Does cauliflower soak up liquid? ›

Cauliflower absorbs water like crazy, and the "granules" will become gummy. To keep it fluffy, just let the moisture in the cauliflower do its work.

Does cauliflower absorb marinade? ›

The vegetables actually absorb some of the marinade, helping to season them from the inside out. All you have to do is toss your vegetables in your favorite marinade and let them sit. That's it.
