FAQ

Can I use frozen squash instead of fresh?

Yes, but thaw completely and drain very well first. Frozen squash releases more water, so extra draining is essential to prevent a soggy casserole.

What if I don't have cornbread stuffing mix?

Substitute with regular bread stuffing mix or make your own by combining crumbled cornbread with herbs and seasonings for similar flavor and texture.

How long will this keep in the refrigerator?

Store covered for up to 3 days. Reheat individual portions in microwave or whole dish in 350°F oven until heated through, about 15-20 minutes.
