The short version: cook bacon in the oven at 200°C (180°C fan, gas mark 6) for 15 to 20 minutes on a lined tray, flipping halfway if you want it even on both sides. Thin streaky bacon is done closer to 12 minutes, thick-cut back bacon can take 20 to 25. No flipping, no spitting fat on your hob, and you can do twelve rashers at once instead of standing over a frying pan doing four at a time.
Why the oven beats the frying pan for bacon
I used to do bacon in a pan because that's what everyone does. Then I worked out that cooking for a houseful of people on a Sunday meant twenty minutes of standing there flipping rashers, getting fat splattered up my arm, while everything else on the plate went cold. The oven solves that. One tray, one timer, done. You get crispy bacon with far less mess and you can get on with eggs or toast while it cooks itself.
It's also more even. A frying pan has hot spots. An oven tray doesn't, as long as you're not overcrowding it.
The exact temperatures and times
- 200°C (180°C fan, gas mark 6): the standard setting. 15 to 20 minutes for regular streaky bacon, check at 15.
- 220°C (200°C fan, gas mark 7): faster and crispier. 10 to 14 minutes. Good if you like your bacon crisp and you're watching it closely, because the gap between "crisp" and "burnt" is about 90 seconds at this heat.
- 180°C (160°C fan, gas mark 4): slower, gentler, more even colour throughout. 20 to 25 minutes. Better for thick-cut back bacon where you want the fat rendered without the edges going hard before the middle's cooked.
If you only remember one number, remember 200°C for 18 minutes. That's the setting that works for most bacon, most ovens, most of the time.
A worked example
Say you're cooking breakfast for six people and you've got a pack of twelve rashers of smoked streaky bacon, average thickness, straight from the fridge. Here's what that looks like in practice:
- Preheat the oven to 200°C (180°C fan) while you're getting everything else ready. This takes most ovens about 10 minutes.
- Line a large baking tray with foil or baking paper. Skip this step and you'll be scrubbing baked-on fat off the tray for twenty minutes later, which is worse than any washing up a frying pan ever gave you.
- Lay the rashers flat, not overlapping. Twelve rashers needs two trays or one large tray, not one squeezed-in tray.
- Put it in the middle of the oven. Set a timer for 12 minutes.
- At 12 minutes, check it. The fat should be starting to render and the edges should be going golden. If you want it crispier, flip the rashers now.
- Give it another 5 to 8 minutes depending on how crisp you like it, checking at the 5-minute mark because this is where it tips from done to burnt fast.
- Take it out, lift the bacon onto kitchen roll or a wire rack for a minute to drain, and that's your six portions sorted with zero standing-over-a-pan time.
Straight from the fridge adds a minute or two compared with bacon that's been sitting at room temperature for twenty minutes. If you're organised enough to take it out early, your timings shift down slightly. Most people aren't that organised, and that's fine, just build in the extra couple of minutes.
Streaky, back and thick-cut: they're not the same job
This is where most guides get lazy and give you one number for "bacon" as if all bacon is the same thickness, which it isn't.
- Streaky bacon (thin, fatty): cooks fast because there's more fat and less meat to heat through. 12 to 16 minutes at 200°C. It also crisps up more reliably because the fat renders out and the thin strip goes brittle.
- Back bacon (meatier, less fat): needs a bit longer, 16 to 20 minutes at 200°C, because there's more lean meat that needs to cook through, not just render fat.
- Thick-cut bacon (American style, or the chunky stuff from a butcher): 20 to 25 minutes, and it does better at 180°C for the first 15 minutes then a blast at 220°C for the last 5 to crisp the outside without drying the inside.
If you've ever followed a "bacon in the oven" recipe and ended up with limp back bacon or burnt streaky, this is almost certainly why: one timing was applied to a different cut than the one the recipe was tested on.
The bit most bacon articles skip
Here's something that doesn't get said often enough: the tray you use matters more than the temperature dial. A dark, heavy baking tray absorbs and holds heat, so bacon on it will cook faster and crisp harder than the same bacon on a thin, shiny tray at the exact same oven setting. I've seen identical timings on two different trays produce bacon that's a full two shades apart in colour. If your bacon never seems to crisp up the way recipes promise, it might not be your oven running cool, it might just be your tray. Swap it before you start blaming the temperature.
The other thing nobody wants to admit is that putting bacon on a wire rack set inside the tray, rather than directly on the tray, gives noticeably better results because the fat drips away instead of the bacon sitting and half-frying in its own grease. It's an extra thing to wash, which is why most people skip it and then wonder why their bacon isn't as crisp as the picture.

Do you need to flip it
No, not really, if your tray is in the middle of the oven and the heat is even from both top and bottom elements (fan ovens especially). Flipping gives slightly more even colour but it's not essential. If you're using a grill function or the top element is doing most of the work, flip halfway or one side will brown much faster than the other.
Checking it's done
Bacon is done when the fat has mostly rendered and gone translucent or golden, and the meat itself has firmed up and lost its pink, raw look. There's no internal temperature check most people bother with for bacon the way you would with chicken, but if you want to be precise, cooked bacon should reach at least 71°C internally. In practice, colour and texture tell you everything you need. If it still looks pale and floppy at the halfway point of your timer, give it longer rather than pulling it early because the recipe said so.
A quick note on safety
Cook bacon until it's no longer pink and the fat has rendered. If you're dealing with any food allergies, intolerances or specific dietary concerns in your household, that's a conversation for a GP or dietitian, not a cooking blog. This post is about timing and temperature, not nutrition or medical advice.
What to do with the leftover fat
Don't pour it down the sink, it'll set and block your pipes eventually. Let it cool in the tray, then either bin it once solid or pour it into a jar and keep it in the fridge for roasting potatoes in later. Bacon fat is one of the best things you can roast potatoes in, better than most oils, and it costs you nothing because you've already paid for the bacon.
Frequently asked questions
What temperature is best for crispy bacon in the oven?
220°C (200°C fan) gives the crispiest result fastest, around 10 to 14 minutes, but you need to watch it closely because it can go from crisp to burnt within about 90 seconds at that heat. 200°C for a slightly longer 15 to 20 minutes is more forgiving and still gives good crisp results.
Do you need to turn bacon over in the oven?
Not usually, as long as it's on a tray in the middle of the oven with even heat from top and bottom. If you're using a grill element or the heat is uneven, flip it halfway through for more even colour on both sides.
How long does thick-cut bacon take in the oven?
Thick-cut bacon needs 20 to 25 minutes, longer than standard streaky or back bacon. A good approach is 180°C for the first 15 minutes to cook it through gently, then raise to 220°C for the final 5 minutes to crisp the outside.
Can you cook bacon straight from the fridge?
Yes, and most people do. It just adds a minute or two to your cooking time compared with bacon that's sat at room temperature for twenty minutes beforehand, because it starts colder and takes longer to heat through.
