Ingredients & Equipment Used In This Recipe
While most ingredients can be bought in grocery stores, for your convenience, any specialized or notable ingredients and equipment needed for this recipe have been linked to Amazon or other stores if available online. Staple ingredients such as oil, salt, sugar, etc., aren’t always included here as you’re likely to have those in your kitchen. The complete list of ALL ingredients with measurements is found on the recipe card.
- Fresh Produce – Cauliflower, Flat-Leaf Parsley

Recipes on The Purple Pumpkin Blog use both cup measurements and/or weighted measurements. American cups and kitchen food scales are handy pieces of equipment to have in your kitchen as it means you’ll be able to make all of the different recipes on my blog. I try to give American, imperial, and metric measurements in my recipes. Please note, that you can mix cup measurements with weighted measurements, but never mix imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, liters, etc.,).
What Is A Gratin?
Gratin is a cooking technique where an ingredient is topped with a browned crust, which is frequently made from breadcrumbs, grated cheese, egg, or butter.
The term can refer to any dish prepared in this manner – you’ve probably heard of potato gratin which is the most common type, but you can also make gratins with pasta, seafood, and vegetables (like our cauliflower gratin!).
Gratin is typically made (and served) in an oven-proof shallow dish after being cooked under an overhead grill or broiler to form a golden crust on top. You can also bake gratin in the oven, which is the method in our recipe.

Recipe Tips
- Storing Leftovers: Cool (within 2 hours), transfer to an airtight container, and store in the fridge for 2 days. Reheat in the oven or microwave until piping hot throughout.
- Freezing Instructions: Not ideal, as the sauce can become watering upon defrosting and change the texture and appearance of the dish. However, it can be frozen if you really need to do so.
- Cool the cooked dish completely (within 2 hours) and wrap in a double layer of plastic wrap and a layer of foil to help prevent freezer burn and keep out unwanted freezer smells. Place on a flat surface in the freezer. Or cool and transfer leftovers to an airtight, freezer-safe container and place in the freezer.
- Label with the name of the dish, thawing/reheating instructions, and the date to keep track of your food storage.
- cauliflower gratin will last in the freezer for up to 2 months.
- To defrost the gratin, unwrap it completely and place it in the fridge to thaw overnight (or at least 12 hours).
- Reheat in the oven (or microwave) until piping hot throughout.
- With all leftovers, make sure the food looks and smells okay before eating.

Ingredients
- 1 tsp extra virgin olive oil

Instructions
- Preheat the oven to 400°F/200°C/Gas 6 and grease a large casserole dish with olive oil.
- Bring a large pot of salted water to a boil. Par-boil the cauliflower for 3 minutes. Drain and return to the warm pot to let the steam dry some of the moisture from the cauliflower. Gently pat dry to remove any remaining moisture.
- Melt the butter in a medium pan over medium heat. Sprinkle in the flour and cook for 2-3 minutes, stirring constantly. This removes the raw taste from the flour.
- Slowly pour in the milk and heavy cream and continue cooking for 2-3 minutes or until the mixture thickens.
- Turn off the heat and add fontina. Stir until the cheese is fully melted.
- Place the cauliflower florets in the prepared casserole dish.
- Pour the fontina béchamel all over the cauliflower. Sprinkle with parmesan cheese.
- Place in oven to bake 20 minutes or until nicely browned and bubbly on top. Remove from the oven and sprinkle with fresh parsley. Enjoy!
