How to Make Cheddar Herb Cauliflower Gratin
- Preheat Oven: Set oven to 375°F (190°C) early so it reaches perfect heat, ensuring your gratin bakes evenly and develops that irresistible, golden-brown, bubbly cheese crust.
- Blanch Cauliflower: Bring a large pot of salted water to a rolling boil, then submerge florets for 3–4 minutes until just tender; drain very well to avoid watery gratin.
- Make Roux: In a saucepan over medium heat, melt butter and whisk in all-purpose flour until it bubbles and turns pale golden, creating a smooth base for your creamy cheese sauce.
- Whisk Milk: Slowly pour in whole milk while whisking constantly to prevent lumps; cook for about 5 minutes until the sauce thickens and becomes silky-smooth, like velvet.
- Melt Cheeses: Remove sauce from heat, then stir in sharp cheddar and half the Parmesan until fully melted and silky, creating that vibrant, tangy cheese flavor in every spoonful.
- Season & Herb: Add minced garlic, chopped thyme, parsley, salt, and pepper to taste, stirring gently to distribute fragrant, herbaceous notes throughout the rich cheese sauce base.
- Assemble Gratin: Toss the drained cauliflower in the cheese sauce, transfer everything into a buttered baking dish, then sprinkle breadcrumbs, remaining Parmesan, and extra cheddar evenly over the top.
- Bake to Golden: Slide the dish into your preheated oven and bake for 20–25 minutes until the topping turns golden-brown and the sauce bubbles enticingly around the edges.
- Rest & Serve: Let the gratin rest for 5 minutes once out of the oven; this resting time helps the sauce thicken, making each serving perfectly creamy without spilling.
Optional: Garnish with extra chopped parsley for a fresh pop of color.

Easy Cheddar Herb Cauliflower Gratin Recipe FAQs
How do I choose the best cauliflower for this gratin?
Look for firm, white heads with tight florets and no dark spots. Fresh cauliflower with crisp leaves is ideal for the best texture and flavor, but frozen florets work well too—just thaw and drain thoroughly before using.
Can I store leftover cheddar herb cauliflower gratin in the fridge?
Absolutely! Store your leftover gratin in an airtight container once it’s fully cooled. It will stay fresh for up to 3 to 4 days when refrigerated at around 40°F (4°C). Reheat gently to preserve that creamy texture and cheesy flavor.
Is it possible to freeze this gratin for later?
Very much so! Freeze your gratin for up to 2 months by letting it cool completely, then wrapping it tightly in plastic wrap and aluminum foil or placing it in a freezer-safe container. When ready, thaw overnight in the fridge and reheat in a 350°F oven until warmed through and bubbly.
What if my cheese sauce turns out lumpy—how can I fix it?
Lumps usually mean the milk was added too quickly or the flour wasn’t whisked thoroughly. To fix, whisk vigorously over low heat until smooth, or strain the sauce through a fine sieve. Next time, add the milk slowly while whisking continuously, and you’ll have that silky, velvety sauce.
Is this gratin safe for pets or people with dairy allergies?
Since this recipe relies heavily on dairy cheeses and butter, it’s not suitable for pets or those with dairy intolerances or allergies. For a dairy-free option, try substituting plant-based milk and cheese alternatives, but note the texture and flavor will differ from the classic version.
