How to Render Lard

Perfect for Baking, Cooking and Frying

I’m mystified by how rare lard has become. Once you’ve used it for any cooking, but especially in pastry or as frying oil, you’ll be mystified too. It has a mild, pleasant flavor, and unlike vegetable oils it doesn’t make foods greasy. Lard used to be widely available. Indeed, there were many lard-type pigs, bred to produce as much fat as possible, with the meat an afterthought.

But the ascendence of soy, the consolidation of the pork industry, and changing consumer behaviors have made lard incredibly hard to find, and incredibly expensive in the rare cases that it is available. This is a shame, but it’s also easily remedied.

The Ingredients

Rendered lard is simply pork fat that has been heated to a liquid state, which allows the removal of connective tissue and other impurities. The word ‘render’ means to do this One confusing aspect has to do with terminology. While most fat on a pig can simply be called pork fat, the fat around the kidneys is called leaf lard, even before it’s been rendered. It just so happens that leaf lard, as the purest fat on the pig, is the most prized. So the goal is to take leaf lard and make it into rendered lard.

Like most farmers who raise pigs I sell leaf lard, but you can also check with your local butcher if you’re lucky enough to have one. Other pig fat works fine, but trim it as carefully as you can. The purer the fat, the milder the flavor.

The Process

Making rendered lard is incredibly easy. While some people prefer to do it on the stovetop, I find this approach more prone to scorching. Better is to cube the fat, put it in an oven safe pot in a low oven, and simply wait. This will give you an excellent yield without any risk of burning the lard.

Something to keep in mind is that the purer the lard, the milder the flavor. So the first lard you remove from the pot, which will be the majority of the total, will be best for baking and frying. The lard from towards the bottom of the pot will have a slightly stronger flavor, which makes it better for cooking fried potatoes or other savory dishes.

Lard is great for everything, but it really does shine in baked and fried goods. Once rendered it keeps basically forever in the freezer and for months in the fridge.

How To Render Lard

Take lard from its raw state to a rendered fat perfect for cooking, baking and frying.
Course Ingredient
Cuisine American
Keyword lard, pastured pork
Prep Time 7 hours
Servings 4 lbs.


  • 5 lbs pork fat preferably leaf lard (see note)
  • ½ cup water


  • Heat oven to 225°
    Chop fat into approximately 1" pieces.
  • Put fat and water in a dutch oven or other oven-safe pot with a a lid. Cover, and put in the oven.
  • After six hours or so check the lard. A large amount of pure fat – it will look like pale yellow oil – should be in the pot. At this point you can ladle off as much as you can into clean jars.
  • Pour off the remainder through a sieve into a clean bowl, then transfer it to a jar.
  • Finally, if you wish to maximize your yield of rendered lard, place the pot on a low burner. With a wooden spoon press the bits of connective tissue remaining in the bottom of the pot, then pour off the last bit of lard.
  • Label the jars. The lard you ladled off first, which should be the vast majority, will have the mildest flavor, suitable for use in pie crusts, cookies, or for frying doughnuts. (Please make yourself some lard-fried doughnuts!)
  • The lard you poured through the sieve will have more impurities and thus a somewhat more pronounced flavor, which means it's ideal for stir fries or cooking crispy potatoes.
  • Store lard in the freezer for maximum freshness, or the fridge if you plan on using it within a couple weeks.


•Leaf lard is the fat from around the kidneys. It is generally considered the best choice, since it yields the purest, mildest-tasting rendered lard. But any pork fat is suitable so long as it is reasonably free from meat, skin, or anything else.


Thank you for this easy recipe. I am waiting my 6 hrs as we speak, I have never done the oven method only the stove top so I’m looking forward to this.

Thank you, I’m going to try this.

Joan Music,

Good question, Felisha. The water should evaporate in the cooking, and if any remains it will be in a layer on the bottom of the pot. If you pour the last bit of lard through a sieve into a bowl, then refrigerate it, you will be able to remove the solid lard from the water.

I’ve also updated teh instructions to advise storing in the freezer. While lard does keep in the fridge or even for a time at room temp, it lasts much better in the freezer.

Thanks for taking the time to write!

Garth Brown,

What about the water? Wouldn’t it turn to mold if left in the lard? I ruined tallow this way so I don’t want to make the same mistake.

Thank you.


Thanks so much for your instructions.
My family is purchasing our first farm raised pig, and I want to make the most of our purchase.
I purchase lard for making tamales, from the grocery store put wouldn’t have to this year 😝
I love that you were willing to share. God bless you!

Roberta Easter,
