The Ultimate Guide: How to Cook Authentic Chicken Schmaltz
Making your own schmaltz is a rite of passage in a Jewish kitchen. It's the ultimate way to ensure "zero waste" while filling your home with the most incredible, savory aroma. Plus, you get a bonus prize at the end: Gribenes (crispy chicken skin cracklings).
Here is a step-by-step guide to rendering your own liquid gold at home.
While you can always buy pre-rendered KJ Chicken Fat to save time, making it from scratch is a beautiful tradition. Here is how to do it right.

1. Gather Your Ingredients
You only need three things to make world-class schmaltz:
-
Chicken Fat and Skin: Save the "trimmings" from your chicken breasts and thighs, or ask your butcher for a bag of fat and skin.
-
Onion: One large yellow onion, roughly chopped. This adds the signature savory depth.
-
A Pinch of Salt: To help draw out the moisture.
2. Prep the Fat
Cut the chicken fat and skin into small, uniform pieces (about 1/2 inch). The smaller the pieces, the faster and more evenly the fat will render.
Pro Tip: Cold fat is much easier to cut. Put your chicken trimmings in the freezer for 15-20 minutes before you start chopping.
3. The Slow Melt
Place the fat and skin in a heavy-bottomed skillet or saucepan. Add a splash of water (about 1/4 cup)—this prevents the fat from scorching before it starts to melt.
Turn the heat to low or medium-low. You want to "render" the fat, not deep-fry it. Stir occasionally. As the water evaporates, the fat will begin to liquefy.
4. Add the Aromatics
Once the fat has mostly melted and the skin pieces are starting to look slightly opaque (usually after 20-30 minutes), add your chopped onions and a pinch of salt.
5. The Golden Stage
Continue cooking on low heat. The onions will soften, and the skin pieces will begin to turn golden brown and crispy.
-
Watch closely: You are looking for a clear, yellow liquid.
-
The Signal: When the onions are dark golden brown and the skin pieces (gribenes) are crunchy and browned, it's done. Be careful not to let the onions burn, or the schmaltz will taste bitter.

6. Strain and Store
Turn off the heat and let it cool for a few minutes.
-
Place a fine-mesh strainer over a clean glass jar.
-
Pour the mixture through.
-
The Prize: Don't throw away the bits in the strainer! Those are the gribenes. Salt them while they are hot and eat them on a piece of matzah or rye bread—they are the "Jewish popcorn."
7. Cooling
Let the jar reach room temperature before sealing. The schmaltz will be a clear amber liquid when warm and will turn into a creamy, opaque pale yellow when chilled in the fridge.

How to Use Your Homemade Schmaltz
-
Matzah Balls: Use a 1:1 swap for oil in your favorite recipe.
-
Sautéing: Use a tablespoon or more to sauté onions for your Roasts.
-
Roasted Potatoes: Toss halved baby potatoes in schmaltz and salt before roasting at 400°F.
How to Store Your Homemade Schmaltz
Proper storage keeps your schmaltz fresh and flavorful for months. Follow these guidelines:
| Storage Method | Duration | Tips |
|---|---|---|
| Refrigerator in a sealed glass jar | 3 to 6 months | Always use a dry, clean spoon |
| Freezer | Up to 1 year | Portion into ice cube tray first for easy use |
Key rule: Always use a completely dry, clean spoon when serving schmaltz from the jar. Even a drop of water introduced into the fat will significantly shorten its shelf life. Store in a glass jar rather than plastic — glass keeps the flavor pure and doesn't absorb odors.
More Ways to Use Your Schmaltz
Once you have a jar of schmaltz ready, the possibilities go well beyond the basics. Here are the best ways to put it to work:
-
Matzah Balls: Use a 1:1 swap for oil in your favorite recipe for lighter, more flavorful balls.
-
Sautéed Onions for Cholent or Soup: A tablespoon of schmaltz in the pan turns simple onions into deeply savory, golden-brown aromatics.
-
Roasted Potatoes: Toss halved baby potatoes in schmaltz, salt, and pepper before roasting at 400°F for 35–40 minutes. Crispier and more flavorful than oil.
-
Traditional Chopped Liver: Schmaltz is the binding fat that gives chopped liver its signature silky texture. Substitute nothing else for authenticity.
-
Potato Kugel: Replace vegetable oil with schmaltz in your potato kugel batter for a richer, more traditional result.
-
Fried Latkes: Use a small amount of schmaltz in your frying oil for latkes with an extra layer of poultry richness and crispness.
-
Chopped Egg Spread (Egg and Onion): Mix schmaltz with hard-boiled eggs and sautéed onions for an authentic kosher deli spread.
Troubleshooting: Common Mistakes When Rendering Schmaltz
Most failures happen for one of these reasons — here's how to avoid them:
-
Too hot, too fast: If you turn the heat up to speed things along, the skin will fry and burn before the fat fully renders. Keep it on low the entire time. If the skin browns in the first 10 minutes, the heat is too high.
-
Onions burning: Add onions only after the fat has mostly melted (20–30 minutes in). Adding them too early causes burning before the schmaltz is ready. If onions burn, the schmaltz will taste bitter — start over.
-
Cloudy or milky schmaltz: This usually means the fat wasn't rendered long enough, or water got into the jar during cooling. The schmaltz should be a clear golden amber when warm. If cloudy, it may go rancid faster — use within a few weeks.
-
Bitter taste: Caused by scorched gribenes or burned onions. Remove any darkened pieces before straining, and reduce heat for future batches.
-
Gribenes won't crisp: They need more time and slightly higher heat toward the end. After the schmaltz is fully liquid, raise heat to medium for the final 5 minutes to help them crisp.
Frequently Asked Questions
How much schmaltz does this recipe yield?
One pound of chicken fat and skin typically yields about 3/4 to 1 cup of rendered schmaltz. The amount varies depending on how fatty the trimmings are.
Can I make schmaltz without onion?
Yes. The onion adds depth and a mild sweetness but is not required. Plain schmaltz (no onion) has a cleaner, more neutral chicken fat flavor — preferred in some recipes where you don't want onion notes.
How long does homemade schmaltz keep?
Properly rendered schmaltz keeps in a sealed glass jar in the refrigerator for 3 to 6 months, or up to 1 year in the freezer. Always use a dry, clean spoon when serving to prevent moisture from shortening shelf life.
What can I do with the gribenes?
Gribenes (the crispy chicken skin bits left after straining) are a delicacy in their own right. Salt them while hot and serve on matzah, rye bread, or challah. They can also be crumbled over a salad or used as a topping for cholent.
Can I use schmaltz for Passover cooking?
Yes — schmaltz is one of the most traditional Passover fats. It is naturally chametz-free and pareve relative to meat dishes. For Passover use, make sure any onion or other additives are also Passover-certified.
Is it worth making schmaltz at home if I can buy it?
Home rendering gives you fresher schmaltz with full gribenes as a bonus, and it uses trimmings that would otherwise be discarded. But if you're short on time, our KJ Chicken Fat is rendered fresh and ready to use straight from the jar.
