About bacon fat

The fat rendered out of bacon during cooking and saved for later use. It is not the same as lard: it comes from cured, salted and usually smoked pork, so it carries salt, curing residues and smoke-derived compounds that plain rendered pork fat does not.

Also known as Bacon grease, Bacon drippings

The evidence in depth

Best supported: Insufficient

What each association actually rests on, and the papers behind it. A rating describes the state of the research, not how impressive the food is. How we rate evidence.

Cardiovascular risk markers

Heart Health
Insufficient evidence

Evidence is limited for bacon fat as such, but the components it carries are not neutral. Observational data links higher processed meat intake with higher cardiovascular and colorectal cancer risk, and the fat carries the saturated fatty acids and sodium of the product it came from. No study has isolated the rendered fat.

Insufficient evidence. Not enough human research to say anything useful yet.

Nutrient values are per 100 g of the USDA reference entry named on this page and vary with variety, growing conditions, storage and preparation.

Source record: Animal fat, bacon grease (USDA FoodData Central, FDC ID 172345).

% DV uses the FDA Daily Values for adults and children aged 4 and over. A dash means no Daily Value has been established for that nutrient.

How preparation changes things

Only effects with real support are listed. If a preparation method is missing, it is because nothing dependable is documented — not because it makes no difference.

Nothing dependable is recorded about how preparation changes this food’s nutritional properties. Rather than guess, this section stays empty.

Things to know

Allergies, interactions and intake concerns. Every food gets this section — a reference where everything is uniformly good is not a reference.

  • Too much

    Carries the salt of curing

    Bacon is cured with salt, and a measurable amount of it comes out with the fat. Cooking with bacon fat is adding sodium as well as fat, which is easy to overlook when seasoning the dish.

  • Worth knowing

    Processed meat residues and smoke compounds

    Nitrite curing produces nitrosamines under high-heat cooking, and smoking deposits polycyclic aromatic hydrocarbons in the fat. Processed meat intake is classified by IARC as carcinogenic to humans on the basis of colorectal cancer evidence, and reusing the rendered fat carries these components forward into other dishes.

  • Too much

    Saturated fat and energy density

    Compositionally it is close to lard: about 40 per cent saturated, pure fat, and as energy-dense as any oil.

  • Worth knowing

    Already cooked once

    Fat that has been rendered in a hot pan has already begun oxidising, and stored bacon fat continues to do so. Reheating it repeatedly compounds that.
