Creamy Cauliflower, Kale & Mushroom Pasta Bake

Ingredients

For the Creamy Cauliflower Sauce:

  • 4 cups vegetable broth
  • 1 large head cauliflower, cut into florets (about 5 cups / 670g florets)
  • 2 tablespoons butter, plus more to butter the pan
  • 5 cloves garlic, minced
  • 1 teaspoon kosher salt
  • ¼ teaspoon black pepper
  • ⅓ cup (78ml) heavy cream
  • 3 tablespoons cassava flour

For the Pasta Bake:

Instructions

  1. Make the sauce: Preheat the oven to 400°F.  Butter a 9x13 casserole dish.
  2. In a large pot, bring the vegetable broth and 2 cups of water to a boil over medium-high heat. Add the cauliflower and cook until super soft and tender, about 15 minutes (the more you cook it down, the creamier your sauce will be, so avoid the temptation to skimp here).
  3. Meanwhile, in a large skillet, melt the butter over medium heat. Add the garlic and saute for 2-3 minutes or until soft and fragrant.
  4. Transfer the cauliflower and all of its cooking liquid (should be about 2 3/4 cups of liquid remaining) as well as the buttery garlic mixture into a blender. Add the salt and pepper and puree until smooth and silky, about 3 minutes (you’ll likely have to do this in a few batches depending on the size of your blender). Whisk in the heavy cream and cassava flour and set aside.
  5. Prep and Assemble the Pasta: Using the same skillet you used to cook the garlic, warm the olive oil over medium heat and add the mushrooms. Cook until just beginning to soften, about 3 minutes. Add the kale and cook until it begins to wilt, about 2 minutes.
  6. Bring a large pot of water to boil. Cook the pasta for 6 minutes – it should still be quite firm (it’ll continue to cook in the oven).
  7. When the pasta’s done cooking, drain it and place it back in the pot. Toss with the cauliflower sauce and mushroom and kale mixture.
  8. Transfer to the prepared baking dish. Sprinkle with Parmesan cheese and breadcrumbs, and bake uncovered for 20 minutes, or until the pasta is bubbling and the top is golden brown.
  9. Allow to cool for at least 10 minutes before serving.
