Begin by preheating the oven to 350°F (175℃). Slightly coat a baking dish that measures 9 by 9 inches.
Combine the base:
Combine all of the eggs in a large bowl and whisk until combined. Cream together the cottage cheese, cheddar, Parmesan, flour, melted butter, baking powder, and salt.
Elevate the taste:
The chopped green onions should be stirred in. Transfer the mixture to the baking dish that has been preheated.
Transfer the dish to a preheated oven and bake for 35 to 40 minutes, or until the center sets and the top becomes golden.
Serve with a garnish and let rest for a little while before slicing. If you want, you may top it off with some red pepper flakes and some fresh parsley.
Have a toasty one.
