Mashed Potato and Cheese on Toast

As a vegetarian, I am always looking for innovative ways to make meals interesting and tasty, as well as nutritious, for the whole family.

Mashed Potato and Cheese on Toast

Mashed Potato and Cheese on Toast

This simple dish made and served in less than 10 minutes (using previously cooked potato) can be spiced up with a little onion and a tomato; and either served on its own for breakfast, as a snack during the day or served with baked beans for a complete light evening meal.

A simple and quick dish made with your leftover mashed potatoes for a tasty snack which is both filling and fulfilling. You could make the mashed potatoes fresh but I often use mashed potatoes saved in the fridge from a previous day's meal to make this quick and tasty snack.

Alternatively you can use 'Instant Mash' which is ok, it's quick to prepare and still makes for a nice snack; but 'Instant Mash' is never as good as the real thing.

10 min

One or two portions per person


  • Mashed Potato
  • Hard Cheese e.g. Cheddar cheese (grated or sliced)
  • Sliced Bread (one or two slices per person)
  • Margarine (or butter)
  • Onion (Optional)
  • Tomato (Optional)
  • Baked Beans (Optional)


  1. Potatoes: Leftover mashed potato from the fridge (potatoes from a previous meal) should be quickly re-heated preferably in the microwave or alternatively by quickly light frying in minimal vegetable oil, or stir-fried.
  2. Slice Bread: Toast the bread under the grill rather than in the toaster. Toast one side to a golden brown, turn the bread over and lightly toast the other side for no more than 30 seconds so that it's crisped but still white.
  3. Cheese, Onion and Tomatoes: While the potatoes are reheating and the bread is toasting thinly slice or grate some hard cheese and optionally finally chop a little onion and thinly slice a tomato.
  4. Baked Beans: If optionally you're serving baked beans with your Potato and Cheese Toasty then put them in the saucepan to heat slowly (occasionally stirring) while you're preparing and cooking your toasties.
  5. To make your Toasty, Butter the crisped but not browned side of the toast (preferably with margarine).
  6. Add a heaped tablespoon of mashed potato on the toast and smooth evenly across the toast with the back of a fork.
  7. Top the potato with a few thin slices of tomato and optionally a thin layer of finally chopped onion.
  8. Add a thin even layer of hard cheese as a final topping, either thinly sliced or grated.
  9. Lower the height of the grill pan to make room under the grill for these 'toasties' (potato and cheese on toast), if the grill pan height is fixed then lower the grill tray (wire try) within the grill pan e.g. turn it upside down.
  10. Place your Potato and Cheese Toasty under the grill and heat until the cheese has melted and is a light golden brown.
  11. Remove from grill and serve with baked beans or as a complete meal on its own.

Mashed Potato Topped With Cheese on Toasted Bread

This is a recipe for making a quick and tasty meal any time of the day or evening using leftover potatoes from your fridge.

If you decide to cook the potatoes fresh rather than using scraps from the fridge you should allow an extra half hour to prepare, cook and mash the potatoes.

The Mashed Potato and Cheese on Toast is a complete meal by itself so can be served on its own (one or two slices per person) or for added substance served with baked beans.

As well as mashed potato and cheese, tomato and onion can optionally be added to each slice of toasted bread individually dependant on individual tastes of each family member and guest.

Serve as a Quick Snack or a Complete Meal

Once Cooked Serve Immediacy either with Baked Beans or on its Own as a Snack

If you've never tried potato and cheese on toast before you may wish to try it on its own for the first time as it is a very filling snack; and if you're rather fond of milk then wash it down with a large glass of milk.

Ideal for a quick lunch on a busy weekend or if you like to have a snack on your lap (served on a tray) in the evening in front of the Telly while watching your favourite TV series then this is an ideal snack for such an occasion.

Quick to prepare and serve, it could almost be done in the adverts; especially if you pause 'live TV' until these Toasties are ready to serve.

Natural Companion Foods and Drinks

Complementary Foods for a Slightly Healthier Meal

You may have noted I suggested milk to wash down your toasty as (for those who like milk) it goes exceptionally well with cheese and other saturated fat foods. This is because milk is one of a number of companion foods that helps to reduce the amount of saturated fat absorbed by the body during digestion.

Drinking lots of milk with fatty foods isn’t an excuse to eat lots of fatty foods but if you are going to indulge in the odd unhealthy but nice snack then why not make it a little less unhealthy by having it with companion foods that reduces the amount of saturated fats digested.

Pineapple is another healthy companion food that goes well with cheese, and which you may wish to include as an optional extra when preparing and serving your potato and cheese on toast.

Likewise margarine is healthier than butter as unlike butter which (although nice) is full of saturated fats margarine is high in polyunsaturated fats.

Grilling Your Food

Oven Grills

In Britain Oven Grills is standard in cookers, I can remember the days when grills use to be set above the hob (at eye level) where these days extractor hoods are fitted. Then for a time dedicated grills use to be between the oven and hob, which these days is where the top oven is situated for double oven cookers; quite often with a grill being incorporated into the top oven. The cooker we have uses the same control for the top oven and grill and switches between the two dependant on whether the door is open (grill) or closed (oven).

When on holiday in France if we book through a British company their caravans on the caravan site include a cooker with oven, grill and hob as standard along with a toaster and microwave. However, when booking through a French company their cookers don’t have grills and a toaster isn’t always supplied as standard so we usually have to clearly specify a toaster as a requirement so that at least we can toast bread.

I guess this reflects a difference in culture in that the French have a continental breakfast which doesn’t include any hot food whereas the British are used to cooked food in the mornings when on holiday.

I’d be interested to learn more about the American Breakfast and how food is grilled e.g. do the American cookers include grills as standard or are the grills a separate appliance.

Thanks for all your feedback, and great recipe tips, all of which sounds delicious.

Connie Clyburn on May 06, 2013:

Yum! Another great lens and sandwich idea!

Aunt-Mollie on January 31, 2013:

This looks like a great after-school snack. I've never thought about using mashed potatoes this way. (In my household, there are never any leftover mashed potatoes. I suppose I could just hide some away.)

Jackie Jackson from Fort Lauderdale on January 31, 2013:

What a great recipe. I'd seen something similar in a wartime recipe book but now I know I must try it - it looks great. With beans too!) Yes, my American cooker has the grill in the oven itself but I definitely remember that days when they were a separate unit!

Elaine Chen on January 31, 2013:

I like any receipt that only require less than 10 minutes for preparation and cooking; thanks for sharing.

SadSquid on January 29, 2013:

This is such an original idea. My contribution to the cuisine of the idle was to use tabasco on cheese on toast. Without tabasco, it's just junk food, but with a few drops of the red stuff, it's a gourmet sandwich. But your idea takes it to a completely different level!

DebMartin on October 26, 2012:

I've got to try this. I can see all kinds of variations after Thanksgiving and my fridge is full of leftovers. It would make a great buffet spread. Just let guest concoct and grill their own creations. Thanks!

I love grilled peanutbutter sandwiches, opened faced. Yummm!! But your recipe will be added to my box. Thanks!
