Cauliflower naturally wants to break into flowerettes, but in the center through the stem you can slice the cauliflower sections with the stem and flowerettes intact. You will get anywhere from 2-4 intact steaks depending on the size of the cauliflower. Don’t despair if they break apart, it will still taste delicious. Buy a couple of cauliflower heads for backup if the cauliflower steaks break apart or if you want your guest to have similar looking pieces.
The kale parsley sauce is a vibrant hybrid of a chimichurri sauce and a pesto. The acid brightens the sauce while the anchovies, capers garlic and hot pepper flakes give it depth. It is a delicious sauce to add some pizzazz to roasted vegetables and meats.
If you have some leftover cauliflower it is delicious stirred into penne or fusilli pasta with some chickpeas and sliced cherry tomatoes, coated with the kale parsley sauce.

Bring a large stock pot half full of water to a boil. Add a teaspoon of Kosher salt to the pot. While the water is combing to a boil, clean and remove the stems from the lacinato kale. Chop the leaves into thirds. When the water reaches a brisk boil, add the kale and blanch for 2 minutes. Remove the kale from the boiling water with a spider or tongs and add to the ice water bath. Once the kale is cool to touch, drain from the water and spread out over a clean lint free kitchen towel. Gently pat dry. Set aside.
Preheat the oven to 375°F / 190°C / Gas Mark 5
Trim away any leaves from the base of the cauliflower head. Rest the cauliflower head on its bottom, stem end down, and cut the cauliflower head in half vertically. Push one half aside and cut ½ inch (1.5 cm) width slices making cauliflower steaks. You might only get two intact cauliflower steaks per side, and the remaining cauliflower may fall into pieces. Repeat with the other half.
Heat a griddle pan or large skillet to medium high heat. I set my griddle to 325°F (160°C). When hot add the cauliflower steaks to the griddle or skillet and sear for about 5-6 minutes a side. Check after 4 minutes to see the progress. You want a nice brown sear along the flat surface of the cauliflower. Carefully turn the cauliflower steaks over and sear the opposite side.
Place the cauliflower steaks on a large rimmed baking sheet and roast in the oven until the cauliflower is tender in the middle, about 10-12 minutes.
Plate the cauliflower steaks on a serving platter or individual plates, and drizzle with the kale parsley sauce. Garnish with pine nuts and chopped parsley and sliced grape tomatoes.
If you want to make this a vegan meal, omit the anchovies and add white miso paste. Start with a teaspoon of miso paste and taste. It will give the kale parsley sauce some body similar to the anchovies, but you lose some of the Tuscan vibe in the sauce. Another alternative is just omit the anchovies and add more capers to your liking.
