My mother always made this while I was growing up. Now I make it for my husband and kids. I cut the biscuits into smaller pieces so they will brown nicely on top. I also sometimes add mushrooms to this recipe because my family likes them so much. —Keri Boffeli, Monticello, Iowa
Preheat oven to 400°. Melt butter in a 10-in. cast-iron or other ovenproof skillet over medium-high heat. Add onion; cook and stir until tender, 2-3 minutes.
