Butternut Squash Casserole Recipe – Oma's Butternutkürbis-Auflauf

This baked squash casserole recipe with tomatoes is covered with blue cheese! "Unusual!" I thought when my German friend, Heidi, had us over for dinner.

She served it with BBQ steak. Delicious! What an absolutely unusual side dish. Since then I have realized that even people who don't like blue cheese, like this dish.
