Ingredient Breakdown
Let’s get to the good stuff! For this creamy and cheesy Parmesan Cauliflower Gratin, you’ll need the following ingredients. Don’t fret if you don’t have a couple of these on hand; this dish is super flexible!
1 medium head cauliflower, cut into florets
Choose a fresh one with firm buds for the best texture! Not a fan of cauliflower? Feel free to swap in broccoli or even Brussels sprouts, totally delicious!1 cup heavy cream
This is where it gets notably creamy. If you’re looking to lighten things up a bit, you could use half-and-half or even milk, but I promise the heavy cream makes it indulgently extra!1 cup freshly grated Parmesan cheese
Trust me, fresh is best here! The pre-grated stuff has anti-caking agents that can affect meltability. We want smooth, creamy goodness!1 cup panko breadcrumbs
These little guys add the crunch we crave; they turn golden brown in the oven. If you’re out of panko, regular breadcrumbs will work too, just not as crunchy but still super good!3 tablespoons unsalted butter
Can’t go wrong with butter to add richness. But if you need a vegan option, olive oil works as well!2 cloves garlic, minced
Because everything tastes better with garlic! You can also use garlic powder in a pinch.1/4 teaspoon nutmeg
I know that sounds a bit unusual, but it brings a warm, nostalgic flavor that’s just heavenly!Salt and pepper to taste
A couple pinches of salt and pepper here can really elevate those flavors, so don’t skip this step!

In a large bowl, combine the steamed cauliflower with the heavenly cheese sauce until each piece of cauliflower is coated with that delicious richness.Bake Till Golden
