Make-ahead Mashed Potato Casserole | RecipeTin Eats

Mashed Potato Casserole is an outrageously scrumptious but extremely sensible technique to make mashed potato forward of time! A layer of cheese and bacon prevents the mash from drying out because it reheats within the oven, whereas reworking this humble aspect into one thing extra-devilish and decadent. Oh the ability of cheese (plus bacon)!

Make it contemporary, or assemble forward and reheat when required. Serve rather than plain ole’ mash.

Make-ahead mashed potato

With the vacations quick approaching, I believed it could be well timed to share my favorite technique to make mashed potato forward of time.

The factor with make-ahead mash is that you just can’t merely reheat it within the microwave or oven. You may suppose a splash of milk and good stir is all it takes to revive it. However I can let you know that’s the trail to a mouthful of gluey horridness.

Whereas there are nifty methods to reheat chilly mashed potato efficiently*, a giant dish of creamy Mashed Potato Casserole takes the prize for probably the most foolproof-yet-show-stopping means I do know! It additionally wins the prize for the bottom effort on the day-of since you actually simply pop the pre-assembled dish into the oven. It’s a win-win, 10/10 – nothing might be extra becoming on your vacation feast menu!!

* How I reheat plain mashed potato: Chilly mash in scorching cream (recipe right here, however notice it’s extra work on the day) or in heavy responsibility piping baggage submerged in boiling water, a trick caterers use (see my demo right here on Instagram).

Is there such a factor as an excessive amount of bacon??

Confession: I feel I used to be just a little heavy-handed with the bacon within the images whereas being a tad quick on the stuff for the recipe video!! So the recipe card as written is a contented medium. 😊

However really, trying on the photograph beneath, it does look fairly engaging with nearly full bacon protection on the floor. And … is there even such a factor as an excessive amount of bacon?? (Yeah nah)

What you want for Mashed Potato Casserole

Right here’s what you’ll want to make Mashed Potato Casserole:

Ingredients in Mashed Potato Casserole
  • Potato – Floury and all-rounder potatoes work greatest to realize a fluffy but creamy mash with out fussing with potato ricers and different devices.
    – Australia: a budget dirt-brushed potatoes bought all over the place (known as Sebago) are ideally suited
    – US: Russet
    – UK: Maris Piper

  • Milk – Our liquid to loosen the potato as much as type mash. If making forward, we add additional (see How To Make part for extra).

  • Bitter cream – I favor utilizing bitter cream relatively than cream in mashed potato casserole as a result of the slight tang makes a pleasant counterpoint to all the opposite richness occurring right here (butter, cheese, bacon). It doesn’t make it bitter within the least. It form of provides creaminess into the mash with out including cloying richness. Does that is smart??

  • Butter – Mash with out butter is just not mash. #strongopinions!

  • Cheese – I take advantage of a mix: Mozzarella for wonderful melty-cheesy-stretchines. Then Purple Leicester for flavour (it’s savoury and a bit sharp, like aged cheddar), and so as to add a stunning orange hue to the mash floor. For those who’re within the States, your orange cheddar is right right here.

    In any other case, use any melting cheese you want (colby and Monterey Jack are different private favourites). For those who decide to make use of mozzarella as your most important cheese, add a handful of parmesan for flavour as a result of mozzarella alone is definitely fairly bland and lacks saltiness.
    Shred your personal – Certainly one of my 5 non-negotiable guidelines said loudly on the primary web page of my cookbook is, “At all times shred your personal cheese”! Retailer-bought pre-shredded cheese is coated in anti-caking brokers which stop it from melting in addition to freshly-grated. I take advantage of an ordinary field grater for the work.
    Pack your cups of cheese – For consistency I favor weight over quantity to measure cheese. So I’ll weigh a hunk of cheese earlier than grating it. However if you’re utilizing cup measures, make sure you pack your cups tightly when measuring the shredded cheese in any other case you’ll be quick. No person needs to be quick on cheese, ever!

  • Bacon – For sprinkling over the casserole floor. Word: I all the time use streaky bacon. As a result of fats = flavour! Additionally, fatty bacon crisps up and hues higher, with out drying out.

  • Inexperienced onion – For a contact of oniony freshness and color.

  • 200g / 6 oz bacon (streaky), chopped (Word 4)
  • 1/4 cup inexperienced onion , finely sliced


Cook dinner bacon:

  • Place bacon in a chilly non-stick pan over medium warmth (no oil). Because the pan heats up the bacon fats will soften. When you see some melted bacon fats, flip the warmth as much as medium excessive and stir for 3 minute or till golden.

  • Drain on paper towels.


  • Potatoes – Peel then reduce into 3cm /1″ chunks.

  • Boil – Place in a big pot and canopy with water so it’s 10cm / 4” above the potatoes. Add 1 tablespoon salt. Deliver to a boil over excessive warmth then cut back warmth so it’s simmering quickly. Cook dinner quarter-hour or till potatoes are very smooth (jab with fork to check, they need to disintegrate).

  • Mash – Add milk (together with EXTRA milk if making-ahead), butter, bitter cream and 1 tsp salt. Mash till {smooth}. (Don’t use meals processor, blender or beater, makes it gluey!)

Recipe Notes:

1. Potatoes – Any starchy or all-rounder potatoes appropriate for making mash will work nice.
2. Additional milk for make-ahead possibility makes the mash looser to consider that mash corporations up when refrigerated. That is the quantity required in order that the reheated dish finally ends up with the identical consistency as when it was freshly made!
3. Cheeses – Mozzarella for wonderful melting qualities, plus Purple Leicester or US cheddar for color and flavour (sub with different cheese of selection like colby, gruyere, Swiss, tasty).
SHRED YOUR OWN for the perfect end result! Retailer-bought pre-shredded is coated with anti-caking brokers so it doesn’t soften as nicely.
PACK your cups tightly when measuring shredded cheese, else you’ll be quick. And no one needs to be quick on cheese, ever!
4. Bacon – You’ll want to use streaky/fatty bacon to make use of this no-oil technique of cooking bacon. For those who use lean bacon, you will want to preheat oil. I do know which possibility I favor! 🙂
5. Dish – A 2 litre / 2 quart baking dish is the best dimension, it is going to be crammed to the brim. A 23 x 33cm / 9 x 13″ dish (3L/3 qt) works superb too – can be crammed about 2/3 of the best way up.
6. Make-head – Retains for 3 days within the fridge, raw, totally assembled aside from the inexperienced onion. Make sure you take it out of the fridge 2 hours previous to reheating to take the coolness out of the it so it reheats extra evenly.
Freezing – A former staff member reported wonderful outcomes freezing the assembled dish, thawing then reheating. However I by no means tried it myself – I’ll come again and replace if (no, when!) I do.
Leftovers will preserve for 3 days, however the mash received’t be as creamy. Think about using it to make mashed potato muffins as a substitute!
7. Diet per serving assuming 12 servings, as half of a bigger banquet.
