How to Make a Dairy-Free Breakfast Casserole

To prepare a dairy-free breakfast casserole, start by preheating your oven to 175°C. Then, prepare your casserole dish by greasing a 22×33 cm dish with coconut oil. Place the hashbrowns evenly in the dish and bake them first. Once they are cooked, remove them from the oven, but leave the oven on.

Next, assemble your ingredients and begin by sautéing onions, peppers, zucchini, and any other preferred vegetables in virgin olive oil until they are tender and aromatic. In a separate mixing bowl, combine eggs (or tofu for a vegan alternative), almond milk (or another non-dairy substitute), and seasonings such as salt, pepper, and herbs. Whisk everything together until well incorporated.

Next, layer the cooked vegetables evenly in the baking dish you greased earlier and pour the egg mixture over the top. For added richness, you can sprinkle dairy-free cheese on top if desired.

Bake the casserole for approximately 30-40 minutes. Monitor the casserole towards the end to prevent overcooking, and make sure it is set in the centre and the edges are golden brown. The result is a flavourful and fulfilling breakfast option that is ideal for hectic mornings.

Storage and Reheating

  1. Transfer your breakfast casserole into an airtight container or tightly cover it with aluminium foil.
  2. Place the casserole in the refrigerator promptly once it has cooled down completelty to prevent bacterial growth.
  3. Ensure your refrigerator temperature is set at or below 4°C to preserve food safety and freshness.
  4. For extended storage, consider freezing the casserole.

Freezing your dairy-free breakfast casserole can extend its shelf life and minimise food waste. Follow these steps for freezing and defrosting:

  • If you have a pre-packaged dairy-free breakfast casserole, it is best to freeze it before midnight on the “use by” date to maintain its freshness and quality.
  • Before freezing, divide the casserole into individual portions or store it in a freezer-safe container.
  • Label the casserole container with the date and contents for easy tracking.
  • When ready to enjoy, defrost the casserole thoroughly before cooking, following the manufacturer’s instructions unless stated otherwise.

When reheating leftovers, it is vital to follow the food safety guidelines to prevent the risk of food poisoning. Here are some tips for reheating your dairy-free breakfast casserole:

  1. Thorough Cooking: When reheating, make sure to thoroughly cook the casserole until it is steaming hot all the way through. This helps kill any bacteria that may have grown during storage.
  1. Oven Reheating: Preheat your oven to 175°C. Move the casserole to an oven-safe dish and cover with aluminium foil to prevent drying out. Bake for around 20-30 minutes or until heated through.
  1. Microwave Reheating: Place a portion of the casserole in a large microwave-safe dishand cover it loosely with a microwave-safe plastic wrap or microwave-safe lid. Heat on medium power for two to three minutes at a time, stirring in between, until heated throughout.

While reheating in either method, stir the casserole occasionally to ensure even heating and check for any cold spots. Use a food thermometer to measure that the internal temperature of the casserole reaches at least 74°C before consuming. Once reheated, serve and enjoy your dairy-free breakfast casserole promptly while it is still hot.
