Nuts About Walnuts: 7 Tasty Recipes to Try

Highly revered in ancient Persia, Greece, and Rome, walnuts weren’t just sustenance; they were symbols of wisdom, immortality, and divine power. While common men were eating acorns, the gods were allegedly eating walnuts. In fact, the Latin name for walnuts became Juglans regia meaning “Jupiter’s acorns,” referring to the Roman god Jupiter (who was the equivalent to the Greeks’ Zeus).

Millennia later, walnuts have seamlessly transitioned from “the food of gods” to modern superfoods, thanks to science-backed research proving their remarkable nutritional benefits. Beyond taste, walnuts boast an exceptional nutritional profile, containing one of the best vegan sources of omega-3 fatty acids. They’re also good sources of vitamin E, B vitamins, and minerals like magnesium, potassium, copper, and zinc.

A 2023 analysis of recent US dietary patterns found that many people are not consuming enough nutrients such as magnesium, fiber, and potassium. For kicks, the researchers asked their computer what would happen if those people added just ¼ cup or about 12–14 halves of walnuts a day to their usual diets, with no other changes. Even that tiny change improved their diet quality and brought their levels of under-consumed nutrients into the “adequate” range.

So what types of walnuts are out there? And if you want to add walnuts to your daily diet (and eat like a Roman god), what are some of the best ways to do so?

Types of Walnuts

There are two main types of walnuts you may encounter in stores and farm stands: English (aka Persian) walnuts and black walnuts. The walnuts you find in the grocery store are almost certainly the English kind. They’re also the ones most often used in cooking, especially in baked goods. They have a soft shell that’s pretty easy to crack with a regular nutcracker.

Black walnuts are the Fort Knox of nuts. They have an extremely hard shell and require industrial-strength tools to open. A friend with a black walnut tree harvests them by spreading them on his driveway and running his truck back and forth over them until the green hulls split open. (He says you can also use a grout mixing bit attached to a corded power drill, but the truck is more fun.)

While there are traditional walnut recipes that include black walnuts or their flour, such as the Pennsylvania Dutch Black John cake, black walnuts are now mainly used in complementary medicine. They’ve been shown to reduce inflammation, which is an underlying cause and contributor to many chronic diseases.

You can also buy or make black walnut oil for sauces and dressings. Handle with care, though; the oil can stain your skin, and the stains can last for weeks, regardless of how much you scrub.

You can easily find shelled English walnuts in most grocery stores. But the unshelled ones are a bit harder to find, especially black walnuts (unless you have your own tree). Look in the bulk bins of natural food stores or in specialty and farmers markets.

How to Store Walnuts

Because walnuts are high in oil, they can go rancid when exposed to warm temperatures for a long period of time. If you’re unsure if they’re still good, give that walnut a sniff. Fresh walnuts smell mildly nutty and have a slightly sweet taste. Rancid walnuts, on the other hand, smell like paint thinner (I’m happy to report that I don’t know what paint thinner tastes like); please don’t eat them.

To keep your walnuts from turning into turpentine, keep them cool, cold, or even frozen. After buying a bag of walnuts, store them unopened in their original packaging. Once you’ve opened the bag, or if you got scoops of them from a bulk bin, keep them in an airtight container. (Here’s a set that we recommend.)

Keep walnuts whole until you’re ready to use them. The happy life span of a chopped walnut is quite short as rancidity is caused by oxidation, and the more exposed surfaces, the quicker the oxygen in the air will turn the oil into something akin to an industrial solvent.

Frozen walnuts can last up to a year or even longer. When you’re ready to use them, transfer them to a refrigerator to thaw, where they’ll remain fresh for up to three months. (Unless, of course, that refrigerator is in a spaceship traveling at the speed of light, in which case something weird happens to time, according to this movie I watched in middle school.)

In the fridge, keep your walnuts separate from strong-smelling foods to prevent them from taking on unwanted flavors. (“Hey, who wants a Fudgy Chocolate Chip and Walnut and Garlic Pesto Brownie?”)

How to Toast Walnuts

Raw walnuts are awesome, and I would never argue with anyone who says that. At the same time, toasting your walnuts can enhance their natural flavor and impart them with a satisfying crunch that goes really well in many dishes.

There are a couple of techniques you can use to toast your walnuts. One is to place them in a single layer on a cookie sheet and bake in a 350° F (175° C) oven for 8–10 minutes until just starting to turn golden brown.

Here’s a short video demonstrating this process, courtesy of the folks at the California Walnut Board:

If you want a more intimate and hands-on experience of walnut toasting, you can toss them in a pan on your stovetop for 2–5 minutes. Since they burn easily, toss and stir often and use medium heat (or even a bit lower, depending on your stove). Do not get distracted, even if your child or significant other comes in, puts on oven mitts, and pretends to be a lobster. Also, make sure not to overcrowd the pan to ensure even roasting.
