How do you make this easy broccoli cheddar squares recipe?

(Full ingredient amounts and instructions available in the recipe card down below).

Preheat the oven to 350 degrees F. Pour the melted butter evenly over the bottom of a 9×13 baking dish. Set aside.

In a large bowl, beat the eggs before whisking in the milk. Then, whisk in the flour, baking powder, salt, and pepper until smooth.

Using a food processor, pulse the broccoli into small pieces to make broccoli rice (you may need to do this in batches).

Add the broccoli rice, diced onion, and grated cheese to the flour mixture.

Here are some recipe tips:

  • Use a food processor to finely dice the broccoli (to make broccoli rice (or riced broccoli).
    • Place the broccoli in a food processor with the S-shaped blade attachment and pulse the broccoli until it turns in small pieces (“rice” consistency).
    • Or use a sharp knife and chop into small pieces.
    • Or use a high-powered blender to make the broccoli rice. You will probably need to blend in batches and scrap down the sides (in between blending) to get even pieces.
  • Use the S-shaped blade attachment to dice up the onion too. Or just use a knife.
  • If you are using a food processor for the broccoli, use it to shred the cheese too.
    • Switch out the S-shaped blade with the shredder blade and you’ve got shredded/grated cheddar in no time.
    • If not, a regular cheese grater will work just as well.

Using a spatula, combine all the ingredients together.

Spread the broccoli cheddar mixture into the baking dish. Bake for 40-45 minutes until set (firm to the touch) in the middle. Let it cool for 15 minutes before slicing into squares. Enjoy warm or cooled!
