Cheesy Squash and Beef Casserole

Meat and potatoes is a go-to favorite when our hungry bunch wants a hearty meal. And as much as we love a good starch served with meat, like pasta or potatoes, there are some super delicious alternatives out there that are just as satisfying. A great potato or pasta substitute is squash. Yellow squash and green zucchini are hearty and almost “meaty” in texture. We love the sweet flavor of the yellow squash, and they’re our favorite way to swap out the usual starch routine for something a little more colorful with great texture and flavor. This cheesy and meaty squash casserole is a perfect example. We used fresh herbs Italian herbs, along with mozzarella and Parmesan cheeses for a hearty, lasagna-like flavor. It’s warm, hearty and full of flavor, and everyone really enjoyed it! A little tweak here and there can turn a conventional meal into a revived classic.
