Make-ahead mashed potato

With the vacations quick approaching, I assumed it might be well timed to share my favorite option to make mashed potato forward of time.

The factor with make-ahead mash is that you simply can not merely reheat it within the microwave or oven. You would possibly assume 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 essentially 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 could possibly be extra becoming to your vacation feast menu!!

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

What you want for Mashed Potato Casserole

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

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

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

  • Bitter cream – I desire utilizing bitter cream moderately than cream in mashed potato casserole as a result of the slight tang makes a pleasant counterpoint to all the opposite richness happening 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 sensible??

  • Butter – Mash with out butter shouldn’t be mash. #strongopinions!

  • Cheese – I exploit a mix: Mozzarella for glorious melty-cheesy-stretchines. Then Crimson 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. When you’re within the States, your orange cheddar is good right here.

    In any other case, use any melting cheese you want (colby and Monterey Jack are different private favourites). When you choose to make use of mozzarella as your primary cheese, add a handful of parmesan for flavour as a result of mozzarella alone is definitely fairly bland and lacks saltiness.
    Shred your personal – Considered one of my 5 non-negotiable guidelines acknowledged loudly on the primary web page of my cookbook is, “All the time 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 exploit a regular field grater for the work.
    Pack your cups of cheese – For consistency I desire weight over quantity to measure cheese. So I’ll weigh a hunk of cheese earlier than grating it. However in case you are utilizing cup measures, make sure to pack your cups tightly when measuring the shredded cheese in any other case you may be brief. No person needs to be brief on cheese, ever!

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

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

    Potato masher – I like to make use of a potato masher that is sort of a spherical disc with holes in it, as pictured above.

Recipe Notes:

2. Additional milk for make-ahead choice makes the mash looser to consider that mash companies 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!

4. Bacon – You might want to use streaky/fatty bacon to make use of this no-oil methodology of cooking bacon. When you use lean bacon, you will want to preheat oil. I do know which choice I desire! 🙂
5. Dish – A 2 litre / 2 quart baking dish is the perfect measurement, it is going to be stuffed to the brim. A 23 x 33cm / 9 x 13″ dish (3L/3 qt) works fantastic too – shall be stuffed about 2/3 of the way in which up.
6. Make-head – Retains for 3 days within the fridge, raw, absolutely assembled aside from the inexperienced onion. Remember to take it out of the fridge 2 hours previous to reheating to take the chilliness out of the it so it reheats extra evenly.
Freezing – A former crew member reported glorious 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 hold for 3 days, however the mash received’t be as creamy. Think about using it to make mashed potato muffins as an alternative!
