What Are Nigella Seeds Anyway?

Nigella seeds—also called kalonji, black onion seeds, or black caraway—are tiny black seeds with a nutty, peppery flavor and a slight oregano-like aroma. They're commonly used in Middle Eastern, Indian, and Mediterranean cooking.

They often show up in breads like naan, pickles, stews, and spice blends such as panch phoron in Indian cuisine.

If you’re missing these little flavor bombs in your pantry, fear not! There are several substitutes you can reach for without sacrificing too much flavor—or sanity.

The Best Nigella Seeds Substitutes

Now let’s roll up our sleeves and explore the best alternatives. Each has its own character, so choose based on your recipe and flavor profile preferences.

1. Cumin Seeds

Cumin seeds are earthy, slightly bitter, and have a warm aroma. While not identical to nigella, they bring a similar weight and texture to dishes.

• Best for: Pickles, rice dishes, and roasted vegetables.
• Ratio: Use an equal amount of cumin seeds.
• Tip: Toast them lightly to boost flavor if the recipe involves dry roasting spices.

2. Caraway Seeds

Caraway has a more intense licorice-like flavor, but it’s quite close in texture and works well in baked goods.

• Best for: Breads, cakes, and some savory pies.
• Ratio: Match the quantity called for in the recipe.
• Caution: Their stronger taste means they won’t work in every recipe.

3. Sesame Seeds (Black Preferred)

Black sesame seeds aren’t just cute—they pack a punch. They lack the aromatic edge of nigella but match the visual appeal and crunchy texture.

• Best for: Decorative topping, breads, and snacks.
• Ratio: Equal parts replacement.
• Extra tip: Lightly toast for extra flavor pop.

4. Poppy Seeds

While mild and slightly sweet, poppy seeds offer a comparable crunch and appearance—especially in baked goods.

• Best for: Bread toppings, muffins, and pastries.
• Ratio: Use the same amount.
• Downside: Lack of heat and herbal notes compared to nigella seeds.

5. Mustard Seeds (Brown or Black)

This might come as a spicy shock, but mustard seeds actually work well in many recipes. They bring a pungent, almost fiery note that mimics the boldness of nigella seeds.

• Best for: Pickles, chutneys, and South Asian dishes where a sharp bite is welcome.
• Ratio: Equal measure substitution.
• Note: Mustard oil released when toasted gives a unique kick—use wisely!

6. Fennel Seeds

Fennel seeds are sweet, slightly licorice-like, and milder than most other options here. Great for subtle applications.

• Best for: Mild curries, vegetable dishes, and certain spice blends.
• Ratio: Same amount, but expect less complexity.
• Pro advice: Combine with coriander for a layered flavor effect.

7. Onion Seeds (Black Shallot Seeds)

Also known as “kala pyaz,” these are sometimes confused with nigella seeds. If available, they’re a near-perfect stand-in.

• Best for: Authentic Indian and Pakistani dishes.
• Ratio: Exactly 1:1.
• Availability: Check Indian or specialty grocery stores.

Pro Tips for Using Substitutes Like a Pro

Swapping spices isn’t rocket science—but a few tricks can take your dish from “just okay” to “oh wow.” Here are some golden rules:

• Toasting matters: Many of these substitutes benefit from a quick dry roast to unlock their full flavor potential.
• Adjust to taste: If using a stronger substitute like caraway or mustard seeds, start with half the amount and build from there.
• Blend it up: Mix two or three different seeds for a layered flavor experience—like fennel + cumin for a DIY spice blend.
• Don’t forget aesthetics: Black sesame or poppy seeds can mimic the visual appeal of nigella seeds in baked goods.
• Label substitutions: If sharing your dish or storing leftovers, keep track of what you used—it helps future you avoid confusion.
