Make it fresh, or assemble ahead and reheat when required. Serve in place of plain ole’ mash.
Make-ahead mashed potato
With the holidays fast approaching, I thought it would be timely to share my favourite way to make mashed potato ahead of time. The thing with make-ahead mash is that you cannot simply reheat it in the microwave or oven. You might think a splash of milk and good stir is all it takes to restore it. But I can tell you that’s the path to a mouthful of gluey horridness. While there are nifty ways to reheat cold mashed potato successfully*, a big dish of creamy Mashed Potato Casserole takes the prize for the most foolproof-yet-show-stopping way I know! It also wins the prize for the lowest effort on the day-of because you literally just pop the pre-assembled dish into the oven. It’s a win-win, 10/10 – nothing could be more fitting for your holiday feast menu!!
- How I reheat plain mashed potato: Cold mash in hot cream (recipe here, but note it’s more work on the day) or in heavy duty piping bags submerged in boiling water, a trick caterers use (see my demo here on Instagram).
Is there such a thing as too much bacon??
Confession: I think I was a little heavy-handed with the bacon in the photos while being a tad short on the stuff for the recipe video!! So the recipe card as written is a happy medium. 😊 But actually, looking at the photo below, it does look pretty enticing with almost full bacon coverage on the surface. And … is there even such a thing as too much bacon?? (Yeah nah)
What you need for Mashed Potato Casserole
Here’s what you need to make Mashed Potato Casserole:
Potato – Floury and all-rounder potatoes work best to achieve a fluffy yet creamy mash without fussing with potato ricers and other gadgets.– Australia: the cheap dirt-brushed potatoes sold everywhere (called Sebago) are ideal– US: Russet– UK: Maris Piper Milk – Our liquid to loosen the potato up to form mash. If making ahead, we add extra (see How To Make section for more). Sour cream – I prefer using sour cream rather than cream in mashed potato casserole because the slight tang makes a nice counterpoint to all the other richness going on here (butter, cheese, bacon). It doesn’t make it sour in the least. It sort of adds creaminess into the mash without adding cloying richness. Does that makes sense?? Butter – Mash without butter is not mash. #strongopinions! Cheese – I use a combination: Mozzarella for excellent melty-cheesy-stretchiness. Then Red Leicester for flavour (it’s savoury and a bit sharp, like aged cheddar), and to add a lovely orange hue to the mash surface. If you’re in the States, your orange cheddar is ideal here. Otherwise, use any melting cheese you like (colby and Monterey Jack are other personal favourites). If you opt to use mozzarella as your main cheese, add a handful of parmesan for flavour because mozzarella alone is actually quite bland and lacks saltiness.Shred your own – One of my five non-negotiable rules stated loudly on the first page of my cookbook is, “Always shred your own cheese”! Store-bought pre-shredded cheese is coated in anti-caking agents which prevent it from melting as well as freshly-grated. I use a standard box grater for the work.Pack your cups of cheese – For consistency I prefer weight over volume to measure cheese. So I’ll weigh a hunk of cheese before grating it. But if you are using cup measures, be sure to pack your cups tightly when measuring the shredded cheese otherwise you will be short. Nobody wants to be short on cheese, ever! Bacon – For sprinkling over the casserole surface. Note: I always use streaky bacon. Because fat = flavour! Also, fatty bacon crisps up and colours better, without drying out. Green onion – For a touch of oniony freshness and colour.

No rocket science here. We make mash, spread it into a casserole dish, top with cheese, bacon and then stop here if making ahead. Finally, on the day of your do, bake it! Otherwise, use any melting cheese you like (colby and Monterey Jack are other personal favourites). If you opt to use mozzarella as your main cheese, add a handful of parmesan for flavour because mozzarella alone is actually quite bland and lacks saltiness.Shred your own – One of my five non-negotiable rules stated loudly on the first page of my cookbook is, “Always shred your own cheese”!

MAKE-AHEAD ADJUSTMENT – If you are making this dish with the intention of serving it the next day, then add an extra 2/3 cup milk. The mash will seem too loose, but this is intentional. It is to factor in the fact that mashed potato firms up when refrigerated overnight. So once reheated, it has the same consistency as when it is freshly made! Potato masher – I like to use a potato masher that is like a round disc with holes in it, as pictured above. It’s the fastest and most effective tool for a smooth mash without using a potato ricer (which I reserve just for Paris Mash, when seeking that next-level-luxe, ultra-smooth, 3-Michelin-restaurant result!).
How to serve Mashed Potato Casserole
This is a dish designed to be a side. (I know we can all picture it moonlighting as a standalone dish after a big night on the turps or a shocking day at work, but it’s meant to take the place of traditional plain mashed potato, I swear.) Because actually, though this has cheese and bacon on it, underneath is all creamy plain mashed potato. So place it on the table or on the buffet alongside the mains and let everybody dig in and help themselves! Try to get in first though. Because you know full well the first in line are going to take more than their fair share of that cheese bacon topping – and we know full well we also cannot blame them….. – Nagi x

Life of Dozer
People have been wondering how Jeff is, our friendly local who lives at my local dog park (Bayview, in Sydney’s northern beaches), an official RecipeTin taste tester. He is doing well! This is how I start every weekend – coffee for Jeff, a ham and cheese croissant for his dog Cubby (sometimes Jeff gets a bite) and Dozer, waiting for scraps – until he gives up and gallops down to the beach to join his mates in the water! Photo captured by Kevin of Unleashed Northern Beaches, a local photographer. Wonderful gift idea: voucher for a private pooch photo shoot!
