Mashed Potato and Cheese Toastie With Baked Bean Option

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 potatoes and cheese toastie with baked beans

This simple dish can be made and served in less than 10 minutes—assuming you have leftover mashed potatoes ready to go. Spice it up with a little onion, tomato and baked beans, and then serve it for breakfast, a snack or a light evening meal.

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'. It's quick to prepare and still makes for a nice snack; however, 'Instant Mash' is never as good as the real thing.

10 min

1 to 2 servings


  • 2 heaped tablespoons leftover mashed potatoes
  • 2 ounces hard cheese (e.g. cheddar), grated or sliced
  • 2 slices bread
  • Margarine or butter
  • 2 tablespoons finely chopped onion (optional)
  • 2 to 4 thin slices tomato (optional)
  • 1 cup baked beans (optional)


  1. Reheat the leftover mashed potatoes, either in the microwave or alternatively by quickly light-frying in minimal vegetable oil or stir-fried.
  2. 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. This side should be crisped but still white.
  3. While the potatoes are reheating and the bread is toasting, thinly slice or grate the cheese. If adding onion and tomato, prepare those as well.
  4. If adding baked beans, put them in the saucepan to heat slowly (occasionally stirring) while you're preparing and cooking your toasties.
  5. Assemble the toastie: Butter the crisped but not browned side of the toast (I use margarine).
  6. Add 1 heaped tablespoon of mashed potato to each slice of toast. Smooth the potato evenly across the toast with the back of a fork.
  7. Optional: Top the potato with a few thin slices of tomato and/or a thin layer of finely 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 the toasties. 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. Toast 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.

Quick but Filling Snack

If you've never tried potato and cheese toasties before you may wish to try it on its own for the first time as it is a very filling snack. 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.

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.

Natural Companion Foods and Drinks

You may have noted I suggested milk to wash down your toastie 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 reduce 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. Butter, although nice, is full of saturated fats margarine is high in polyunsaturated fats.
