Do you have suggestions to turn this into a cheesy hash brown ham casserole? Love your recipes! I am a single person household and the smaller serving sizes are so helpful!

Hi Jennie, I have not tried making this with ham but I think you could easily stir in diced ham during step 6. Let me know if you try it and how it turns out for you. Thanks :)

I have made this recipe multiple times and always get compliments with people wanting me to share the recipe. I make it in 4 ramekins so everyone has their own serving bowl. It's a big hit!

Hi Zona, I want to make these for a girls brunch. I'm planning on making them in ramekins for individual servings. Should I adjust baking time.

Hi Sandy, A good rule of thumb is to set your timer for half the amount of time called for in the original recipe. In this case I would start checking for doneness around 15 minutes to be safe.
