What size casserole dish?
I used a 9 x 13-inch baking dish but another idea would be a smaller but deeper baking dish. Or you could make individual servings in individual ramekins if you have a set.
Nothing beats a hearty and filling breakfast like this one. Absolutely good and my kids love it, too!
Thanks for sharing this amazing recipe. My family loved it. I will be sharing this recipe with my friends too!
