Step‑by‑Step Instructions for Broccoli Cheddar Squares
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it heats up, take a moment to evenly butter a 9×13 baking dish, ensuring the bottom and sides are well-coated. This step helps prevent the delicious Broccoli Cheddar Squares from sticking during baking, allowing for easier removal once they’re done.
Step 2: Prepare the Batter
In a large mixing bowl, crack in the eggs and whisk them thoroughly until well-beaten. Add in the milk, all-purpose flour, baking powder, sea salt, and black pepper. Blend these ingredients together until the mixture is smooth and free of lumps. This batter will serve as the foundation for your savory Broccoli Cheddar Squares.
Step 3: Process the Broccoli
Take your fresh broccoli florets and place them into a food processor. Pulse the broccoli until it resembles “broccoli rice,” which should take about 10–15 seconds. The finely chopped broccoli will blend seamlessly into the batter, giving your Broccoli Cheddar Squares that vibrant green color and a delightful texture.
Step 4: Combine Ingredients
Transfer the processed broccoli into the bowl with your batter. Then, add the diced onions and freshly grated cheddar cheese, stirring until everything is evenly incorporated. Ensure that the mixture is well-mixed but avoid over-stirring, as maintaining a light texture is key for the final outcome of these Broccoli Cheddar Squares.
Step 5: Pour into the Baking Dish
Carefully pour the broccoli and cheese mixture into the prepared baking dish. Use a spatula to spread the mixture evenly across the dish, ensuring all corners are filled. This allows for even cooking and ensures that each square will have a consistent texture and flavor when baked.
Step 6: Bake to Perfection
Place the baking dish into your preheated oven and bake for 40-45 minutes. You’ll know they’re ready when the center feels firm to the touch, and the top is a lovely golden brown. Keep an eye on them towards the end of the baking time to prevent over-browning.
Step 7: Cool and Slice
Once baked, remove the dish from the oven and let it cool for about 15 minutes. This cooling period is crucial as it will help firm up the squares, making them easier to slice. After cooling, cut them into squares, ready for serving!

How to Store and Freeze Broccoli Cheddar Squares
Fridge: Store Broccoli Cheddar Squares in an airtight container for up to 5 days to maintain freshness. Make sure they are completely cooled before sealing.
Freezer: For longer storage, wrap individual squares tightly in plastic wrap and place them in a freezer-safe bag or container. They can last for up to 3 months without losing flavor.
Reheating: To reheat, simply place the squares in the microwave for 1–2 minutes or bake at 350°F (175°C) for about 10-15 minutes until heated through.
Serving: Enjoy these savory squares warm or at room temperature, making them perfect for busy meals or as a tasty appetizer.
