Mashed Cauliflower au Gratin Recipe

Unless someone tells you, you might not know you're eating cauliflower. But if you do like cauliflower, you'll love this version. It's buttery, cheesy, creamy and wow. —Sandie Parker, Freeland, Michigan
TOTAL TIME: Prep: 40 min. Cook: 40 min. YIELD:12 servings


  • 2 large heads cauliflower, broken into florets
  • 1-1/2 cups shredded Parmesan cheese
  • 1 cup shredded Colby-Monterey Jack cheese
  • 6 tablespoons butter, cubed
  • 3/4 teaspoon garlic salt
  • 1/2 teaspoon Montreal steak seasoning
  • 1 cup (4 ounces) Italian-style panko (Japanese) bread crumbs
  • 1/4 cup butter, melted


  • 1. Preheat oven to 350°. Place cauliflower in a stockpot; add water to cover. Bring to a boil. Reduce heat; simmer, uncovered, 10-12 minutes or until very tender. Drain; transfer to a large bowl. Mash cauliflower; stir in cheeses, cubed butter and seasonings. Transfer to a greased 3-qt. or 13x9-in. baking dish.
  • 2. In a small bowl, mix bread crumbs and melted butter until evenly coated; sprinkle over cauliflower mixture. Bake, uncovered, 40-50 minutes or until heated through and topping is golden brown.

"made this for Easter dinner. it was a great hit. next time I will adjust the cheese levels to make it a bit healthier. Not sure if I had small heads (they were average in store) but definitely would not have served 12"

"Mmmm - great combination. I put in three dollops of organic sour cream, 1/2 tsp. granulated garlic, moistened with 1/2 cup cooking water, 1 cup grated Parmesan & skipping the bread crumbs. Putting the cheese combo on top to bake."

"My husband and I love this. I only make about half of the recipe. I probably end up with a little more cheese by doing this, but we love cheese. Be sure to use freshly grated parmesan cheese."

"I made this for Thanksgiving and was asked to bring it back again for Christmas dinner. Very good, the key is using a nice aged parmesan cheese shredded just before cooking."

"We are a veggie loving family but the flavors just did not feel right in this dish. It was lacking. I felt it needed to be creamier."

"I changed the recipe a little to lessen the calorie content. I cut the recipe in half, used about 1/2 cup Parmesan, divided, 1/2 cup reduced fat cheddar cheese, 1 T. butter, cubed. 1/2 cup Panko bread crumbs, with about 1/8 cup Parmesan cheese, 1 T. butter and about 1/4 tsp smoked paprika. Very delicious."
