Shepherd's Pie in advance?

Hi, just wondering if it’s safe to prepare a shepherds pie 2-3 hours in advance of baking it in the oven - can I leave it out or does it need to be refrigerated?

It is winter here so not particularly warm in my kitchen and I have limited fridge space. As the meat.potato mixture will be cooling for a period of time anyway, would leaving it out for a few hours before dinner be ok?

Thanks

I wouldn’t risk leaving it out, but if it is cold enough you can put it in a plastic box out on the porch or balcony.

I think it should be fine, prepare, let set and then bake. I love shepherd’s pie. How do you make yours, if I may ask?

I would leave it out for 2-3hrs without hesitation.
