Blanching the cauliflower before freezing

To blanch the cauliflower, start by washing the head and removing any dirt or debris. Cut the head of cauliflower in half, then into quarters. Remove the florets from the core and break them into smaller pieces. Next, bring a large pot of water to a boil. You can add salt to the water at a ratio of four teaspoons per gallon of water. Add the cauliflower and blanch for 1-3 minutes. Remove the cauliflower from the pot with a slotted spoon or skimmer and transfer it to a bowl of ice water to stop the cooking process. Let the cauliflower chill for about 2 minutes, then drain and pat the florets dry to remove any excess moisture.

Once the cauliflower is blanched and dried, spread the florets in a single layer on a baking sheet and pre-freeze for 1-2 hours. Finally, transfer the partially frozen cauliflower to freezer bags or containers and store them in the freezer for several months.

Freezing without cooking first

Freezing cauliflower cheese before cooking is a great way to increase its shelf life. It can be frozen for up to three months. However, it's important to note that freezing it will affect the texture of the cauliflower and the sauce. The cauliflower may become mushy, and the sauce may become thin and loose.

To freeze cauliflower cheese without cooking it first, you can follow these steps:

  • Prepare the cauliflower by washing it and cutting it into evenly sized florets.
  • Blanch the cauliflower by placing the florets in boiling water or steam for a maximum of five minutes.
  • Immediately transfer the blanched cauliflower to a bowl of iced water to stop the cooking process.
  • Drain the excess water from the cauliflower thoroughly. Too much water will result in more ice crystals forming during freezing, making the dish watery after thawing.
  • Place the cauliflower in a freezer-proof container or baking dish. You can also use individual baking dishes if you plan to freeze portions separately.
  • Prepare the cheese sauce by making a roux with butter, flour, and milk. Whisk the mixture until it thickens.
  • Stir in most of your grated cheese into the sauce. You can use a combination of cheeses such as mature cheddar, red Leicester, or gruyere, depending on your preference.
  • Pour the sauce over the cauliflower in the baking dish and stir to combine.
  • Sprinkle the remaining cheese and breadcrumbs on top for added texture and flavor.
  • Wrap the baking dish tightly with plastic wrap or tinfoil to prevent freezer burn.
  • Label the dish with the date and contents before placing it in the freezer.

When you're ready to cook the frozen cauliflower cheese, simply remove it from the freezer and bake it directly from frozen. The dish can be baked in the same casserole dish you used to freeze it, making it convenient for reheating. Follow the standard baking instructions, but allow for a longer cooking time since you're starting from frozen.

Roux sauce as a base

Freezing cauliflower cheese before baking is possible, but the quality will suffer. If you want to freeze it, prepare the dish up to the baking stage in a freezer-proof pan, wrap it well, and freeze for up to three months. Bake it directly from frozen.

Now, for a roux sauce as a base:

A roux sauce is a mixture of butter and flour that serves as a thickening agent for the cheese sauce. It is a fundamental component that holds the sauce together. To create a roux, melt butter in a saucepan over medium heat. Once the butter turns golden brown and emits a nutty aroma, add the flour. The general rule is to use equal amounts of flour and butter, adjusting the quantities based on the desired thickness of the sauce. For a standard sauce with a creamy consistency, use the same amount of butter and flour, such as 30g, 40g, or 50g of each. If you prefer a thicker sauce, simply increase the amounts of butter and flour while keeping the amount of liquid the same.

After creating the roux, gradually add the liquid component, such as milk or cream, while whisking continuously to prevent lumps. As the mixture thickens, slowly incorporate more liquid, ensuring a smooth and refined sauce. The type of dairy used will impact the final consistency; whole milk creates a rich, creamy sauce, while low-fat milk results in a lighter flavor. For an ultra-creamy sauce, opt for heavy cream, but use it sparingly to avoid making the sauce too rich.

Once the sauce reaches the desired consistency, stir in seasonings like salt and nutmeg. Finally, add the cheese. For a sharp, tangy taste, a blend of cheddar and parmesan is a great choice. Alternatively, for a milder flavor, combine mozzarella and gouda for a smooth and velvety texture.

Crispy cauliflower with roasting

Freezing cauliflower cheese before cooking is not recommended as it may affect the quality of the dish. However, if you wish to have crispy cauliflower with roasting, here is a detailed guide:

Preparing the Cauliflower:

Start by cutting your cauliflower into evenly sized florets, ensuring each piece has a flat side. This flat side will allow the cauliflower to rest flat on the baking sheet and achieve a nice golden brown colour during roasting. You can cut the cauliflower into 3-inch florets, or larger sizes if you prefer, but maintaining even sizing is crucial for even cooking. If time permits, wash the florets and let them air dry for up to 2 days before roasting, or use pre-washed florets to avoid excess moisture.

Seasoning and Oil:

Place the cut cauliflower into a large bowl. Drizzle or toss the cauliflower with olive oil, ensuring each piece is generously coated. You can also add other seasonings to the bowl, such as kosher salt, black pepper, garlic powder, paprika, cayenne pepper, or a combination of your choice. Mix well to ensure the cauliflower is evenly seasoned. Remember that garlic, in particular, can add a nice flavour boost to your dish.

Roasting:

Preheat your oven to 220°C/425°F (200°C fan) to achieve a high-temperature cooking environment. Place an empty baking sheet in the oven as it preheats. This step is essential, as it ensures that the baking sheet is hot and dry when you place the cauliflower on it, promoting caramelization and preventing the cauliflower from steaming in its juices. Once the oven and baking sheet are preheated, carefully remove the hot baking sheet and place it on a heatproof surface. Drizzle about 1/4 cup of olive oil evenly across the baking sheet. Then, place the seasoned cauliflower florets flat side down on the tray, making sure they are spaced evenly apart.

Roast the cauliflower in the oven for 20-30 minutes, depending on your desired level of doneness. For the first 15-20 minutes, avoid turning the cauliflower to allow a nice crust to form. Then, flip the florets and continue roasting for another 5-10 minutes until they are golden brown and crispy. Keep an eye on the cauliflower, and if it hasn't reached the desired crispness by the 30-minute mark, continue roasting in 5-minute intervals.

Serving:

Once your cauliflower is roasted to perfection, you can serve it as a delicious side dish. It is tasty on its own, but you can also add toppings or sauces for extra flavour. A sprinkle of Parmesan cheese, lemon juice, parsley, coriander, or cilantro can enhance the dish. If you want to get creative, try a drizzle of Tahini Sauce or Lemon Yogurt Sauce. You can even add other vegetables to the mix, such as carrots or asparagus. Enjoy your crispy roasted cauliflower!

Freezing and reheating

Freezing Cauliflower Cheese

Cauliflower cheese can be frozen for up to three months. However, freezing affects the texture of the dish, making the cauliflower softer and mushier, and the cheese sauce thinner. To minimise these effects, it is important to prepare the dish properly before freezing.

Firstly, do not overcook the cauliflower before baking. It is best to blanch or sauté the cauliflower before freezing, as these methods reduce the water content of the vegetable, preventing it from becoming mushy after freezing and thawing.

To blanch the cauliflower, place the florets in boiling water or steam for a maximum of five minutes, then immediately transfer them to a bowl of iced water to cool. Blanching stops the enzymes that affect colour, flavour, and structure, helping to preserve the vegetable. After blanching, be sure to strain the excess water to avoid excess ice crystal formation during freezing.

Sautéing the cauliflower is another option, which involves briefly steaming the cauliflower before frying it in a pan. This method dries up the water, reducing the number of ice crystals formed during freezing and enhancing the flavour of the dish.

Once the cauliflower is prepared, assemble the dish in a freezer-proof pan or baking dish, and wrap it well in plastic wrap or tinfoil before placing it in the freezer.

Reheating Cauliflower Cheese

To reheat cauliflower cheese, bake the dish from frozen in the oven. Remove any plastic wrap or foil and follow the baking instructions for the dish. This will ensure the cauliflower is cooked through and the sauce is bubbling and browned.

Cauliflower cheese can also be reheated in the microwave, although this may affect the texture and consistency of the dish. If reheating in the microwave, ensure the dish is defrosted and heated through, stirring occasionally to ensure even heating.
