Ingredients for Parmesan Cauliflower Gratin

Now, let’s talk about the simple treasures we need for this creamy bake.
You don’t need fancy ingredients, just good quality basics that sing together.
I always find that using fresh ingredients makes all the difference, especially the cheese.
The exact measurements are waiting for you down below in the printable recipe card.
Essential Components for the Creamiest Bake
We are building layers of flavor, starting with the humble star of the show.
I promise you, these simple items transform into something truly spectacular.
The Brassicas and the Base
You will need one large head of cauliflower, cut into lovely little florets.
Make sure they are roughly the same size so they cook evenly.
For the base of our velvety sauce, we use butter and all-purpose flour.
These two are the dynamic duo for creating the essential roux.
Achieving the Perfect Sauce (The Roux and Dairy)
Next up is milk, which is the heart of our creamy Béchamel sauce.
I usually use whole milk for the richest, most decadent flavor possible.
Seasoning is key here, so grab your salt, black pepper, and a tiny bit of nutmeg.
That little pinch of nutmeg really brightens the whole dish unexpectedly.
The Star Cheese: Parmesan and Optional Additions
The main event is, of course, the grated Parmesan cheese.
Please grate it fresh if you possibly can; it melts so much better!
I sometimes add Gruyere or cheddar if I’m feeling extra cheesy, but it’s totally optional.
A little panko breadcrumbs mixed with the remaining Parmesan makes the perfect golden crust.
How to Make Parmesan Cauliflower Gratin
Making this creamy **Parmesan Cauliflower Gratin** is much easier than you think.
We will break it down into simple, manageable steps, so you feel totally confident.
Remember, cooking should be joyful, not stressful, so take your time.
I find that having all my ingredients prepped beforehand makes everything flow smoothly.
Preparing the Cauliflower Florets
First, preheat your oven and grab your favorite baking dish.
You want a 9×13 inch dish, lightly greased and ready for action.
Now, steam or boil your cauliflower florets until they are just tender-crisp.
I like them still slightly firm because they will soften more in the oven later.
Draining the cauliflower really well is critically important, sweet friend.
Excess water is the enemy of a thick, luxurious cheese sauce, so shake it dry.
Spread the prepared florets evenly across the bottom of your baking dish.
They are waiting patiently for their creamy, cheesy shower!
Mastering the Béchamel Sauce
The Béchamel is the soul of any proper gratin, and it’s surprisingly simple.
Don’t be intimidated by the fancy name; it’s just a white sauce.
Creating the Roux Base
In a medium saucepan, melt your butter over a nice medium heat.
Whisk in the flour right away and cook it for just one minute.
This cooked flour and butter mixture is called a roux, and it smells nutty.
Cooking the roux removes that raw flour taste, which is essential.
Infusing Flavor and Thickness
Slowly whisk in the milk, making sure to eliminate any lumps immediately.
Keep stirring frequently until the sauce begins to bubble and thicken nicely.
This process usually takes about five to seven minutes, so be patient here.
Once it coats the back of a spoon, your sauce is perfectly done.
Take the saucepan off the heat and stir in your salt, pepper, and nutmeg.
Nutmeg is the secret ingredient that gives this sauce its classic, warm depth.
Making it Cheesy: Incorporating the Parmesan
This is where we turn a simple white sauce into a rich, creamy cheese sauce.
Add three-quarters of your Parmesan, plus any optional Gruyere or cheddar.
Stir everything until the cheese is completely melted and the sauce is perfectly smooth.
The aroma that fills your kitchen right now is absolutely heavenly, isn’t it?
Assembling the Parmesan Cauliflower Gratin
Now, pour that gorgeous, cheesy sauce evenly over the cauliflower.
Gently toss the florets around a bit to ensure every piece is coated beautifully.
You want all those nooks and crannies filled with the creamy, savory liquid.
This ensures maximum flavor in every single bite of **cheesy cauliflower**.
Baking to Golden Perfection
In a small bowl, mix the remaining Parmesan with your optional panko breadcrumbs.
Sprinkle this topping evenly over the entire surface of the gratin.
The panko adds a fantastic, irresistible crunchy texture to the dish.
Bake it for about 20 to 25 minutes, until it’s golden brown and delightfully bubbly.
The edges should be sizzling, and the crust should look wonderfully crisp.
Let it rest for five minutes before you serve it, allowing the sauce to set up.
Tips for Success
A few little tricks can make your **Parmesan Cauliflower Gratin** truly sing.
These simple pointers will guarantee a perfect result every single time.

- Stir in some roasted garlic or caramelized onions for deeper flavor.
Making a Heartier Parmesan Cauliflower Gratin

FAQs about Parmesan Cauliflower Gratin
Can I Prepare Parmesan Cauliflower Gratin Ahead of Time?
Yes, absolutely! This is a great make-ahead dish for busy days.
You can assemble the entire gratin, including the topping, up to 24 hours in advance.
Cover it tightly and keep it chilled in the refrigerator until you are ready to bake.
Just add about 10–15 minutes to the total **baked cauliflower** cooking time.
What is the Best Substitute for Parmesan Cheese in this Gratin?
If Parmesan is not your jam, try using grated Pecorino Romano for a sharper flavor.
Or, use a good quality aged white cheddar mixed with a little Asiago cheese.
The goal is a hard, salty cheese that melts well and delivers strong flavor.
You need that depth to balance the richness of the creamy Béchamel.
How Do I Prevent My Gratin Sauce from Breaking or Separating?
The key is controlling the temperature, especially when adding the cheese.
Always remove the Béchamel from the heat before stirring in the cheese.
If the sauce gets too hot after the cheese is added, it can seize up or separate.
Also, make sure your milk is warm when you add it to the roux for a smoother transition.
Is Parmesan Cauliflower Gratin Freezer-Friendly?
While you technically can freeze it, I don’t usually recommend it, honestly.
The texture of the sauce can sometimes change and become a little grainy upon thawing.
If you must freeze it, thaw it completely in the refrigerator overnight before baking.
It tends to be much creamier and more delicious when baked fresh.
Final Thoughts
See? That wasn’t scary at all, was it?
This **Parmesan Cauliflower Gratin** is truly a simple pleasure.
It’s a perfect example of how basic ingredients can create profound comfort.
I hope this recipe brings warmth and happy sighs to your dinner table tonight.

- Total Time: 50 minutes
- Yield: 6-8 servings
- Diet: Vegetarian
Description
A creamy and cheesy cauliflower gratin baked with a rich Parmesan sauce, perfect as a side dish.
Ingredients
- 1 large head cauliflower, cut into florets
- 3 tablespoons butter
- 3 tablespoons all-purpose flour
- 2 cups milk
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon nutmeg
- 1 cup grated Parmesan cheese, divided
- 1/2 cup shredded Gruyere or cheddar cheese (optional, for extra cheesiness)
- 1/4 cup panko breadcrumbs (optional, for topping)
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
- **Prepare the Cauliflower:** Steam or boil the cauliflower florets until they are tender-crisp (about 5-7 minutes). Drain well and spread them evenly in the prepared baking dish.
- **Make the Béchamel Sauce:** In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1 minute, stirring constantly (this is the roux).
- Gradually whisk in the milk until smooth. Continue cooking, stirring frequently, until the sauce thickens and comes to a simmer (about 5-7 minutes).
- Remove the saucepan from the heat. Stir in the salt, pepper, and nutmeg.
- **Make it Cheesy:** Add 3/4 cup of the Parmesan cheese (and the optional Gruyere/cheddar) to the sauce and stir until melted and smooth. Reserve the remaining 1/4 cup of Parmesan.
- **Assemble the Gratin:** Pour the cheese sauce evenly over the cauliflower in the baking dish. Gently toss to ensure all the florets are coated.
- **Top and Bake:** In a small bowl, mix the remaining 1/4 cup of Parmesan cheese with the optional panko breadcrumbs. Sprinkle this mixture evenly over the top of the gratin.
- Bake for 20-25 minutes, or until the topping is golden brown and bubbly.
- Let it rest for 5 minutes before serving.
Notes
- For a richer flavor, use whole milk.
- Ensure the cauliflower is well-drained before adding the sauce; excess water can thin the sauce.
- The nutmeg is crucial for authentic Béchamel flavor, but use sparingly.
- If the sauce seems too thick, add a splash more milk until the desired consistency is reached.
