Can I make this ahead of time?

Yes, and truth be told, it might taste even better the next day. That is how Southern flavors settle and sing. Cook it fully, cool, refrigerate, and reheat gently.

How long does it keep in the fridge?

Properly stored in an airtight container, it will keep for 3 to 4 days. For longer keeping, freeze single portions and thaw in the refrigerator overnight.

Can I use frozen potatoes?

You can use frozen diced potatoes, but watch the cooking time. They may cook faster and become soft sooner, so check a little earlier to prevent overcooking.

Is the ranch seasoning necessary?

The ranch packet brings a comforting, herby backbone that many families love. If you prefer less sodium or want a homemade touch, substitute with a mix of dried parsley, garlic powder, onion powder, and a pinch of salt.

Can I make this in an instant pot?

Yes, you can adapt it for an instant pot. Brown the meat in the sauté function, layer the potatoes and other ingredients, and use the slow cooker mode or pressure cook with a careful timing adjustment. If you use pressure, release steam carefully and allow some resting time for the sauce to thicken. These answers come from years of feeding people who want dependable, warming meals. I always answer with patience because the slow cooker is a teacher of gentle methods.
