Can You Eat a Black Walnut: Edible or Inedible?
The answer to whether black walnuts are edible or not is not straightforward. While they are safe to consume, not all parts of the black walnut tree are edible. The tree produces a fruit that looks similar to a green tennis ball, which contains the edible part of the nut. The nut itself is protected by a thick, hard shell that can be difficult to crack open.
The fruit of the black walnut tree is not edible and can actually be toxic to some animals, such as horses. The husk of the fruit contains a chemical called juglone, which can be harmful to plants and animals. It is important to wear gloves when handling the fruit, as the juice can stain your skin and clothes.
The nut inside the fruit, however, is safe to eat. It is important to note, however, that the nut has a very strong flavor and can be bitter if not prepared properly.
Preparation
If you’re interested in trying black walnuts, the first step is to crack open the shell. This can be done using a hammer or a nutcracker. Once the shell is cracked, you’ll need to remove the edible part of the nut, which is the kernel inside.
To remove the kernel, you can use a nut pick or a small knife. Be careful not to crush the kernel, as it can be difficult to remove if it is damaged. The kernel can be eaten raw, but it is often roasted or toasted to bring out its flavor and reduce bitterness.
Here are some ways to prepare and eat black walnuts:
- Roasting: Spread the kernels out on a baking sheet and roast in the oven at 350°F (175°C) for 10-15 minutes, or until they are lightly browned and fragrant.
- Toasting: Toast the kernels in a dry skillet over medium heat, stirring occasionally, until they are lightly browned and fragrant.
- Chopping: Chop the kernels and use them as a topping for oatmeal, yogurt, or salads.
- Baking: Add black walnuts to your favorite baking recipes, such as cookies, muffins, or breads.
Risks and Precautions
While black walnuts are generally safe to eat, there are some risks and precautions to be aware of.
- Allergic reactions: Like other nuts, black walnuts can cause allergic reactions in some people. If you have a nut allergy, it is important to avoid black walnuts and other tree nuts.
- Overconsumption: Black walnuts are high in fat and calories, so it is important to eat them in moderation. Consuming too many black walnuts can lead to weight gain and other health problems.
- Interference with medication: Black walnuts contain a compound called juglone, which can interfere with some medications, including blood thinners. If you are taking medication, it is important to talk to your doctor before adding black walnuts to your diet.
How To Store Black Walnuts?
Storing black walnuts properly is important to maintain their freshness and flavor. Here are some tips for storing black walnuts:
- Shell the nuts: Black walnuts should be shelled as soon as possible after harvesting or purchasing. The longer the nuts remain in their shells, the more difficult they are to remove. Use a nutcracker or a hammer to crack open the shells and remove the kernels.
- Dry the nuts: Once the nuts are shelled, spread them out in a single layer on a clean, dry surface. Allow them to air dry for several days until the moisture has evaporated. Stir the nuts occasionally to ensure that they dry evenly.
- Store in a cool, dry place: Once the nuts are dry, store them in an airtight container in a cool, dry place. A cool pantry or cupboard is ideal. Avoid storing black walnuts in the refrigerator, as the cold temperature can cause them to become rancid.
- Freeze for long-term storage: If you have a large quantity of black walnuts, you can freeze them for long-term storage. Place the dry nuts in an airtight container or freezer bag and store in the freezer for up to one year.
- Use within 6 months: While black walnuts can be stored for several months, they are best used within six months of harvesting or purchasing for optimal flavor and freshness.
By following these simple storage tips, you can enjoy the unique taste and nutritional benefits of black walnuts for months to come.
Conclusion
So, can you eat black walnuts? The answer is yes, but with some caveats. The kernels inside the nut are safe to eat and can be a healthy addition to your diet.

Black walnuts can also be bitter if not prepared properly, so it is important to roast or toast them before eating.
Overall, black walnuts are a nutritious and flavorful nut that can be enjoyed in a variety of ways. Just be sure to eat them in moderation and be aware of any potential risks or precautions.
