Prep Time

Cook Time


  • cubed
  • cut into florets
  • minced
  • divided
  • 1 oz. heavy cream
  • 3/4 tsp. salt
  • 1/2 tsp. ground black pepper
  • 1/2 tsp. dried thyme



Preheat oven to 350 degrees Fahrenheit.

In a large pot, steam squash, cauliflower, and garlic cloves until tender, 5 to 7 minutes.  

Drain vegetables very well in a colander, shaking to remove any excess water, and then transfer half to a food processor. Puree until smooth and transfer to a large bowl, then repeat with remaining vegetables.

Stir half of the Parmesan, the cream, salt, pepper, and dried thyme.

Transfer pureed vegetables to a 3 to 4 quart glass or ceramic baking dish and spread out smoothly.  

Top with remaining Parmesan and bake for 30 minutes.

Turn broiler on high and broil 5 minutes to brown topping.

Serve hot.
