Step 1

Bring a large pot of water to boil. Cook the pasta for 5 minutes – it should still be a little firm. Drain, toss with a drizzle of oil, and set aside.

Step 2

Bring a large pot of water to a boil, add the cauliflower, and cook for 5 minutes until tender-crisp. Meanwhile saute the minced garlic with a tablespoon of butter. Using a slotted spoon, transfer the cooked cauliflower to a blender with 2 cups broth, milk, oil, salt, and sauteed garlic. Puree until very smooth. You might need to do this in batches.

Step 3

Preheat the oven to 400 degrees. Heat the 3 tablespoons butter in a very large skillet. Add the mushrooms and saute until golden brown.

Step 4

Toss the cooked pasta, cauliflower sauce, and mushrooms together. Add the remaining cup of broth to help the consistency stay saucy.

Step 5

Transfer to a deep 9×13 baking dish. Sprinkle with cheese and bake uncovered at 400 for 10-15 minutes. Some of the moisture from the mushrooms will seep out – give it a quick stir to reincorporate it and make it creamy. Top with fresh sage ribbons.
