Heat the oven to 350 and place 4 sage leaves on a baking sheet. Cook for about 5 minutes until crispy. Remove and set aside.
In skillet, heat oil and add butternut squash, cooking until half tender. Add minced garlic and lightly sauté.
Add in cauliflower. If using fresh, add a splash of water to give some moisture and help cook. Cook until either thawed or slightly tender.
Turning the heat down, add about 1/4 of the stock and cook until liquid is evaporated. Continue this until all the stock has been absorbed, adding slowly as you go.
When the stock is used up, the cauliflower should be tender. Switch to the cream with the same process of adding slowly until the liquid evaporates, then adding more.
Once you switch to cream, it's time to add your seasoning! Toss in chopped sage, nutmeg and the cheese. Salt and pepper to taste.
When all liquid has been absorbed, this should have a rich consistency and very creamy. Serve immediately topped with a toasted sage leaf. Enjoy! Variation: a lot of classic risotto recipes will call for a splash of white wine. Add a few tbsps after the stock is absorbed but before the cream for an added flavor!
