Can I make this casserole ahead of time?
Yes. Assemble the casserole (without tater tots) up to 24 hours ahead, cover, and refrigerate. Add tater tots and bake just before serving to keep them crispy.
How do I know when the tater tots are done?
Bake until the tater tots are golden brown and crispy on top, about 30–35 minutes at 350°F. They should be firm, not soft.
Can I use fresh potatoes instead of frozen tater tots?
Frozen tater tots are essential for the crispy texture. Fresh potatoes won't achieve the same result and would require longer cooking.
What can I substitute for ground beef?
Ground turkey or ground pork work as alternatives. Use the same amount and cook until browned. Ground chicken may be too lean and less flavorful for this dish.
How should I reheat leftovers?
Cover and reheat in a 350°F oven for 15–20 minutes until warmed through. The tater tots will soften slightly but remain edible.
