How to Make a Toastie in a Frying Pan
A frying pan toastie needs three things: medium-low heat, a weight pressing the sandwich flat, and patience. Cook it 3–4 minutes a side on a non-stick pan at about medium-low, with a lid or a second pan on top so the cheese melts before the bread over-browns.
Quick answer: Preheat a non-stick or cast-iron pan for 2 minutes on medium-low (around 4 of 9 on most induction hobs, a gentle steady flame on gas). Cook the buttered toastie 3–4 minutes, pressed under a saucepan, flip, and cook 3 minutes more with a lid on.

Recipe: Frying pan cheese toastie
Ingredients
- 2 slices medium-sliced white or wholemeal bread
- 55g mature cheddar, coarsely grated
- 10g salted butter, softened
- 1 tsp mayonnaise, optional, for the outside
- Small pinch of English mustard powder or 1/2 tsp English mustard, optional
Method
- Put a 24–28cm non-stick or cast-iron frying pan on medium-low heat for 2 minutes. A drop of water should sizzle gently, not spit and vanish instantly.
- Butter one side of each slice right to the crusts (for extra crunch, mix the butter with the mayonnaise first).
- Place one slice butter-side down in the pan, scatter over the cheese and mustard, and top with the second slice butter-side up.
- Press down with a fish slice, then set a heavy saucepan or a second frying pan on top. Cook for 3–4 minutes until the underside is deep golden.
- Remove the weight, flip the toastie carefully, and cover the pan with a lid (or a heatproof plate) for the second side. Cook for 3 minutes, until the cheese is running at the edges.
- Slide onto a board, rest for 1 minute so the cheese sets slightly, then cut diagonally.
Why low heat and a weight matter
Bread browns at well below the temperature it takes to melt 50g of cheese through a slice of bread above it. On high heat the outside is dark in 90 seconds and the middle is still cold. Medium-low gives the heat time to travel through the bread while the butter turns the surface golden rather than black.
The weight does what the plates of a toastie maker do: it presses the bread into full contact with the pan, so you get an even, flat crust instead of brown patches, and it compresses the filling so the cheese bonds both slices together. The lid on the second side traps heat and finishes the melt.
Heat settings by hob
| Hob type | Setting | Time per side | Tip |
|---|---|---|---|
| Induction (1–9 scale) | 4–5 | 3 min | Heats fast; don't preheat on boost |
| Ceramic / electric | Medium-low (4 of 9 or "M-") | 3–4 min | Slow to respond; turn down before it gets too hot |
| Gas | Low-medium steady flame | 3–4 min | Flame shouldn't lick up the sides of the pan |
| Cast-iron pan, any hob | One notch lower than above | 3–4 min | Holds heat; the second side cooks faster |
Which pan to use
A heavy-based non-stick pan is the easiest: even heat, nothing sticks, and you can use a little less butter. Cast iron gives the crispest crust but runs hotter on the second side, so turn the heat down a touch after flipping. Avoid thin, cheap aluminium pans if you can; they create a hot ring above the burner and burn the middle of the bread while the edges stay pale.
A ridged griddle pan gives panini-style stripes but less overall browning. If you like that style, our toastie maker vs panini press comparison explains the difference.
What to use as a weight
- A smaller saucepan, base down, with a tin of beans inside for extra weight.
- A second frying pan of the same size, which gives the most even pressure.
- A foil-wrapped brick (the classic "pollo al mattone" trick) if you make these often.
- A cast-iron grill press, if you already own one.
Whatever you use, make sure the base is clean and heatproof, and don't leave plastic-handled pans sitting over the flame.
Other methods
An air fryer toastie is more hands-off (180°C, 7–8 minutes with a flip). For four or more at once, the oven toastie method is easier than juggling pans. An electric sealed toastie maker is still fastest at 3–4 minutes and is the only way to seal in loose fillings like beans; see the classic cheese toastie recipe for timings including deep-fill and panini presses. All the options side by side are on how to make a toastie without a toastie maker.
Variations
- Ham and cheese: one folded slice of ham; add 30 seconds to the second side. See ham and cheese toastie.
- Cheese and onion: fry half a thinly sliced onion in the pan first for 6 minutes, then use it as the filling.
- Kimchi and cheese: squeeze 40g kimchi dry; the pan crust handles it well. Recipe: kimchi cheese toastie.
- Parmesan crust: sprinkle 1 tbsp grated parmesan into the pan just before each side goes down for a lacy, crisp edge.
Mistakes to avoid
- Butter in the pan instead of on the bread: it pools and burns in the middle while the edges stay dry.
- Too much cheese: unsealed sides mean anything over about 60g oozes out and burns in the pan.
- Constant flipping: one flip only. Each lift loses the contact that builds the crust.
- The wrong cheese: pre-sliced "burger" cheese melts but tastes of little; a mature cheddar or a blend is better. See best cheese for toasties.
FAQs
Should I use butter or oil in the pan?
Butter spread on the bread gives the best flavour and colour. Oil in the pan works but soaks unevenly into the bread and can make it greasy. Mayonnaise on the outside is a good alternative with a higher smoke point than butter. More on this in butter or mayo for toasties.
Why is my pan toastie burnt outside but the cheese not melted?
The heat is too high. Turn it down to medium-low, grate the cheese rather than slicing it, and use a lid on the second side to trap heat.
Can I make a pan toastie without a lid?
Yes. Keep the weight on for both sides instead, and add about a minute to the second side. A heatproof plate upturned over the pan also works as a lid.
How do I make two at once?
A 28cm pan fits two square slices side by side. Use a second frying pan on top as the weight so both are pressed evenly.
