Creamy Bratwurst Casserole

Jump to Recipe

A delicious rosemary cream sauce baked over bratwurst, potatoes, and green beans – comfort food at its finest! The cream sauce is so easy to make but has such a rich and inviting creamy flavor. And the potatoes and green beans cook up to the perfect texture with just enough bite but cooked through.

Creamy Bratwurst Casserole

I actually used leftover bratwurst from two nights prior. So they were cold but cooked when I put them in. If you are cooking them specifically for this recipe, I would suggest cooking them first before prepping the potatoes and green beans. This will let them cool off a bit before you cut them into chunks, and they will retain the moisture better.

I used fresh green beans so that they would stay a little crunchy to provide some texture to the dish. You can use frozen (I would put them in frozen not thawed) or canned (make sure to drain them completely) if you can’t find fresh. After making it, I think you could also sub out the green beans for asparagus if you like that better! I used Yukon Gold potatoes but you could use russets or red potatoes too.
