When I first attempted this Sunday Roasted Cauliflower Gratin, I was pleasantly surprised by how simple yet decadent it turned out. The key is to roast the cauliflower until it's tender and slightly caramelized before mixing it with the rich cheese sauce. This depth of flavor makes all the difference!
One of my favorite tips is to use a combination of cheeses: a sharp cheddar for that tanginess and a creamy Gruyère for that wonderful melting quality. The result is a gratin that is not only delicious but also visually appealing, making it a standout dish at any table.

Gathering the Right Ingredients
Using fresh cauliflower is essential for achieving the best flavor and texture in your Sunday Roasted Cauliflower Gratin. Look for a head that feels heavy and has tightly packed florets without any brown spots. The variety of cheeses plays a pivotal role here; sharp cheddar adds a robust flavor, while Gruyère provides a creamy, nutty undertone. If you're keen on experimentation, consider adding a bit of smoked Gouda for a smoky twist or even a sprinkle of blue cheese for depth.
The heavy cream not only enriches the cheese sauce but also ensures a luxurious mouthfeel. If you're looking for a lighter version, substitute the heavy cream with half-and-half, but note that it may alter the creaminess. For a vegan variation, you can use cashew cream mixed with nutritional yeast and a vegan cheese alternative, which would provide a similar flavor profile without the dairy.
Mastering the Roasting Process
Roasting the cauliflower at 400°F (200°C) is key to caramelizing the natural sugars, resulting in a sweet and nutty flavor. Pay close attention to the florets as they roast; after about 20 minutes, give them a stir to ensure even cooking and avoid burning. You're looking for a golden brown color and a tender texture before combining them with the cheese sauce. This step not only enhances flavor but also adds a nice textural contrast to the creamy sauce.
If you find your oven runs hot, you may need to reduce the temperature slightly or check the florets a few minutes earlier. Avoid overcrowding on the baking sheet; if necessary, spread them out over two sheets. There's a fine line between perfectly roasted and overly charred, so be vigilant and keep an eye on them during the last few minutes of roasting.
Baking to Perfection
Once you've layered the roasted cauliflower with the cheese sauce, baking is where the magic truly happens. Aim for a bubbling consistency and a golden crust on top, which typically occurs in about 15-20 minutes. If your gratin isn’t browning to your liking, switch on the broiler for the last 2-3 minutes—just be sure to watch it closely to prevent burning. This method will create a delightful contrast between the creamy interior and the crunchy topping.
Another tip is to let the gratin sit for a few minutes after removing it from the oven. This will allow the sauce to thicken slightly, making it easier to serve. For added flair, garnish with freshly chopped herbs like parsley or chives before serving for a pop of color and freshness.

Make sure to measure out all ingredients before you start for the best results!
Instructions
Follow these steps to create your gratin:
Preheat and Prepare
Preheat your oven to 400°F (200°C). On a baking sheet, toss the cauliflower florets with olive oil, salt, and pepper. Roast for about 25 minutes, or until golden brown and tender.
Make the Cheese Sauce
In a saucepan over medium heat, combine the heavy cream, cheddar, and Gruyère cheeses. Stir continuously until melted and smooth. Add the Dijon mustard, garlic powder, nutmeg, and mix well.
Combine and Bake
In a baking dish, layer the roasted cauliflower and pour the cheese sauce over the top. Sprinkle with Parmesan and breadcrumbs, if using. Bake for 15-20 minutes or until bubbling and golden.
Allow the gratin to cool slightly before serving. Enjoy as a side or main dish!
Pro Tips
- For an extra layer of flavor, consider adding sautéed onions or caramelized leeks along with the cauliflower before baking.
Storage and Reheating
This gratin can be made ahead of time, making it a fantastic option for meal prep. If you're preparing it a day in advance, roast the cauliflower and assemble the dish without baking. Cover it tightly and store it in the refrigerator. When ready to serve, simply pop it in the oven and bake until hot and bubbly, possibly extending the baking time by a few minutes if it’s coming straight from cold.
Leftovers can be stored in an airtight container in the fridge for up to three days. Reheat individual portions in the microwave, or place in an oven-safe dish and warm in the oven at 350°F (175°C) for about 15 minutes. You might need to add a touch more cream to prevent it from drying out during reheating.
Serving Suggestions
This Sunday Roasted Cauliflower Gratin pairs beautifully with a variety of main dishes. Consider serving it alongside roasted chicken, grilled fish, or even a hearty vegetarian option like stuffed bell peppers. It’s a wonderful side that adds a layer of richness to any meal, making even humble fare feel special.
For a complete meal, you can also turn this gratin into a main dish. By adding cooked proteins like shredded chicken or sautéed mushrooms, it transforms into a luscious one-dish dinner option. Just ensure that the additional ingredients are added to the layer of roasted cauliflower before covering with the cheese sauce for an even distribution.
