How Long to Cook Bacon in the Oven?

The complete guide to oven bacon

Once you’ve cooked bacon in the oven, the stovetop method starts to feel a little silly. No splatter, no babysitting, no crowded pan, no flipping — just lay it flat on a sheet, set the timer, and walk away. Half the battle is knowing the right temperature; the other half is knowing what “done” looks like for the texture you actually want.

Why the oven beats the stovetop

A skillet cooks bacon from one side at a time, in a puddle of its own rendered fat that flexes the heat unevenly. You spend the whole time hovering, flipping, and dodging spatter. The oven cooks the entire surface at once with consistent radiant heat — every strip gets the same treatment, the fat renders into a flat sheet on the pan instead of steaming the meat, and the slices come out flat and uniform. Your stovetop stays clean, and you can cook a full pound at once instead of three slices at a time.

The right temperature

400 °F is the sweet spot. Hot enough to crisp the edges and fully render the fat, not so hot that the meat burns before the fat’s done. You’ll see recipes call for anything from 350 °F to 425 °F — at the lower end your bacon spends too long swimming in its own grease and goes greasy and floppy; at the higher end the edges burn before the middle’s done. Splitting the difference at 400 °F is the consensus pick across America’s Test Kitchen, The Kitchn, and most professional kitchens.

Time cheat sheet

From a fully-preheated oven at 400°F (204°C)204°C (400°F):

• Regular bacon: 13 min chewy · 16 min medium crispy · 19 min extra crispy.
• Thick-cut bacon: 18 min chewy · 22 min medium crispy · 26 min extra crispy.

These are the centers of the published ranges, and the timer above will fine-tune them for your oven over time — every kitchen has its quirks. After two or three runs you shouldn’t need to think about it.

Chewy vs. crispy: knowing what done looks like

Bacon is one of the few foods where there’s no single “correct” doneness — texture preference is personal. Here’s what each stage looks like:

• Chewy: Mahogany-red meat, pale-yellow fat that’s mostly opaque. A strip lifted with tongs bends easily without breaking. Best for BLTs, where the bacon needs to flex around the bread.
• Medium crispy: Deep mahogany brown across the meat, fat looks translucent and shimmering. The strip is firm but not brittle — it has a slight curl, doesn’t flop. The classic American breakfast bacon.
• Extra crispy: Almost-dark brown, fat fully rendered and glassy. A strip will snap when you press it. This is the bacon you crumble over salads, scatter on baked potatoes, or stack next to scrambled eggs for the contrast.

The cold-oven-start trick (your biggest lever)

If your bacon comes out curled and uneven no matter what you do, try this: put the bacon on the lined sheet, slide it into a cold oven, then turn the oven on to 400°F (204°C)204°C (400°F). As the oven heats up, the fat renders slowly and gradually instead of being shocked into shrinking. The result: flatter slices, more even cook, dramatically less splatter. The downside is it adds about 5 minutes to the listed time (the preheat counts as cook time), and it ties up your oven for longer. The default flow above uses a preheated oven because it’s faster and more predictable; if you’re chasing perfectly flat bacon, switch to cold-start.

Rack or no rack?

A wire rack set inside the rimmed baking sheet lifts the bacon out of the rendered fat and lets air circulate beneath it, which makes the bottom crisp slightly more. The tradeoffs: it’s another thing to wash, the rendered grease that drips through is harder to save (it gets stuck under the rack), and skinny slices can fall through some rack grids. For most home cooks, flat on parchment or foil is plenty crisp. Use a rack if you’re cooking for company and want bacon that snaps like a cracker.

Common mistakes

• Overlapping the slices. Touching is fine, overlapping isn’t. Where two slices touch, they steam instead of crisp, and you get wet, pale bacon stuck together.
• Skipping the rim. Bacon renders a startling amount of fat. A flat cookie sheet will spill grease into your oven within minutes. Always use a sheet with a 1-inch rim.
• Opening the door to peek. Every peek drops the temperature 25 °F or more, adding a minute to the cook each time. Watch through the window.
• Cooking on a cold sheet (when preheating). If you’ve preheated the oven, the sheet should be room-temperature, not pre-warmed — a hot sheet shocks the fat and curls the bacon. Conversely, if you’re using cold-start, the sheet AND the oven start cold together.
• Pulling at “looks done.” Bacon keeps cooking out of the oven for another 30–60 seconds. Pull when the color is one shade lighter than what you want on the plate.
• Letting it sit in its own grease. Even on the rest plate, bacon left in a puddle of fat re-absorbs and goes soggy. Move it to fresh paper towels if you’re holding it for more than a minute.

Storing leftovers

Cooked bacon keeps 4–5 days in the fridge at or below 40°F (4°C)4°C (40°F) in an airtight container. Cool the strips to room temperature first — a hot lid traps condensation and turns the bacon limp. To reheat, the oven is best (350 °F for about 10 minutes brings back most of the crisp); the microwave works in a pinch (10 seconds per strip) but the texture turns brittle rather than snappy. The air fryer is excellent for reheating: 350 °F for 3–4 minutes.

Saving the bacon grease

Don’t throw out the rendered fat — it’s one of the best cooking fats you can have on hand. While it’s still warm and pourable, strain it through a fine mesh sieve (or coffee filter) into a clean glass jar. Catching the burnt bits is what extends the shelf life from weeks to months — left in, those cracklings turn rancid fast. Sealed in the fridge, strained bacon fat lasts 3–6 months; in the freezer, 6–12 months. Use it for frying eggs, popping popcorn, sautéing greens, roasting potatoes, or anywhere you’d use butter or olive oil and want a smoky-savory note underneath.
