FAQs
How can I make this casserole ahead of time?
I prepare the beef mixture in advance and store it in the fridge. When ready to bake, I assemble the casserole and pop it in the oven.
Can I use fresh potatoes instead of tater tots?
Yes, diced and roasted potatoes work well, but they won’t have the same crispy texture as tater tots.
Is there a way to make this casserole healthier?
I swap ground beef for lean turkey and use a lighter cheese blend to cut calories. Cauliflower tots are also a great alternative.
What can I serve with this casserole?
A simple side salad, roasted veggies, or even a light coleslaw pairs perfectly with this dish.
Can I use store-bought Big Mac sauce?
Absolutely! If I’m short on time, I grab a bottle of store-bought Big Mac sauce to drizzle on top.
