You know the dishes that are so simple, yet so satisfying?
This Cheesy Cauliflower Bake is one of those dishes for me.
Why I love this recipe:
We ate a ton of cauliflower (and broccoli!) sprinkled with cheddar cheese when I was a kid.
I recently updated the recipe to include a decadent, silky smooth and absolutely tasty cheddar cheese sauce.
It’s basically like macaroni and cheese without the pasta… on top of cauliflower.
I love this Cheesy Cauliflower recipe because it’s pretty hands-off, and it cooks up in less than an hour.

Let’s talk ingredients!
In addition to the tools above, you’re going to need some ingredients to make this recipe, too! Chances are, you might already have some of them in your fridge or pantry. Scroll down to the recipe card for the full measurements and instructions.
Here’s what you need:
- Cauliflower—I used a fresh cauliflower, but you could easily use frozen, too. You’ll need around 5 cups total.
- Unsalted butter—this forms the base of our roux. While you could swap it out with a neutral oil, I love the creaminess the butter adds to the dish.
- All-purpose flour—I keep unbleached AP flour in my house, but the regular kind works, too. I have not attempted to make this roux with a gluten free flour, so I do not recommend it at this time.
- Milk—this is the liquid element to our cheese sauce. You can use whatever milk you’ve got on hand. While I like to use at least 2% or whole milk, you could get away with 1% or skim, too.
- Extra sharp cheddar cheese—grate your own and enjoy! You can use yellow or white cheddar.
- Grainy dijon mustard—this adds flavor, as well as cuts through the richness of the cheese sauce to balance it out. Don’t skip it. You could use a regular dijon if you don’t have grainy.
- Spices—we’re using a combination of kosher salt (medium grain, please and thank you), black pepper (freshly ground!), garlic powder and cayenne pepper to season this cheesy sauce. We’ll also add a little sweet paprika on the top for color.
How to make Cheesy Cauliflower
Preheat the oven to 375°F. Spray a baking dish with nonstick baking spray.
Add the cauliflower florets to the baking dish. Drizzle with a little olive oil. Season with a pinch of salt and pepper.
Roast the cauliflower for 25 minutes.
Alternately, you could steam the cauliflower in the microwave or on the stovetop for a faster dish. I like to bake mine, though, for the added flavor.
How to make the cheese sauce
While the cauliflower bakes, make the cheese sauce.
Melt the butter over medium-high heat in a large saucepan or a nonstick skillet.
Whisk in the flour, continuing to whisk as it heats and darkens into a blonde roux.
Slowly pour in the milk, whisking vigorously as you pour so the mixture doesn’t have lumps.
When the milk has been added, measure in the mustard.
Turn off the heat, and add the grated cheese. Stir vigorously until combined.
Season with salt, pepper, garlic powder and cayenne pepper.
Pour the cheese sauce over the cauliflower, and toss to combine. Sprinkle the paprika on top.
Bake for an additional 30 minutes or until bubbly and delicious.
Frequently Asked Questions

Yes. You can remove the brown spots from a cauliflower so long as they are not mold spots.
