How to Make Fresh Chili Harissa: North Africa’s Legendary Hot Sauce
Turn peppers and spices into a flavor-packed paste that elevates any dish.

Harissa is a bold, flavor-packed chili paste from North Africa that has become indispensable in home kitchens worldwide. This renowned condiment combines fresh chili peppers with aromatic spices and olive oil, resulting in a paste that brings heat, smoke, and complexity to everything from tagines to grilled meats, dips, and roasted vegetables.
What Is Harissa?
Harissa is a North African chili paste traditionally made by pounding or blending hot red peppers with spices like caraway, coriander, cumin, garlic, and olive oil. While its roots are Tunisian, harissa is integral to Moroccan and Algerian cooking and has inspired countless regional and personal variations, from chunky pastes to smooth sauces. Harissa’s flavor is subtly smoky, deeply savory, and pleasantly pungent, with an underlying brightness from lemon or vinegar.
Fresh Peppers vs. Dried Peppers: Which Harissa?
The defining flavor and texture of harissa depend on the peppers you use. Many modern recipes embrace the boldness of fresh, hot red chilies. Traditional North African harissa typically relies on dried hot chilies, rehydrated and ground for a denser, more shelf-stable paste.
- Fresh pepper harissa: Offers vibrant color, juiciness, and bright, vegetal flavors. The result is less preserved, needs refrigeration, and is best within a week or so.
- Dried pepper harissa: Delivers a smokier, more intense flavor with a longer shelf life, but less of the lively green nuance of fresh chilies.
Both versions can be customized by choosing different chilies—from mild to fiery—and mixing in sweet peppers or even roasted bell peppers for added depth.
Key Ingredients in Fresh Chili Harissa
- Fresh red chilies: Choose vibrant, ripe chilies, mixing types for complexity.
- Mild harissa: Use fresno, red jalapeños, or sweet red bells.
- Hot harissa: Add serrano, cayenne, or even bird’s eye chilis.
- Garlic: Essential for background heat and pungency.
- Spices: Whole caraway seeds, coriander seeds, and cumin seeds are traditional. Toast and grind them just before blending for maximum aroma.
- Olive oil: Carries flavor and softens the paste, giving harissa its signature texture and sheen.
- Acid: Lemon juice or vinegar brightens the flavors and helps preserve the paste.
- Salt: Balances and preserves.
Optional Ingredient Variations
- Roasted red peppers: For body and sweetness, use roasted bell or sweet red peppers alongside the chilies.
- Tomato paste: Some recipes add a spoonful for umami and color.
- Dried mint or other herbs: Add just a pinch for an herbal note.
Step-by-Step: How to Make Fresh Chili Harissa
- Prepare the chilies:
- Stem the chilies. Seed them if you want a milder paste.
- Roast (optional): For deeper flavor, broil chilies and sweet peppers until blistered, then peel and chop.
- Toast and grind spices:
- Lightly toast whole caraway, coriander, and cumin seeds in a dry skillet over medium heat until fragrant (1–3 minutes).
- Grind to a fine powder with a spice grinder or mortar and pestle.
- Blend the paste:
- Add chilies, garlic, spices, lemon juice or vinegar, olive oil, and salt to a food processor.
- Blend to a textured paste. Add more oil for a looser, sauce-like consistency.
- Taste and adjust:
- Fine-tune heat, salt, acidity, and oil to your preference.
- Store:
- Transfer the paste to a sterilized jar. Press plastic wrap directly onto the surface or cover with a thin layer of oil.
- Refrigerate. Use within a week for peak freshness; always use a clean utensil to avoid contamination.

Customizing Your Harissa
Harissa is endlessly adaptable. Consider making it your own:
- If you prefer extra heat, substitute a portion of the fresh chilies for spicier varieties, or include seeds.
- To boost fruitiness, add a sweet red pepper or a teaspoon of tomato paste.
- Add a smoky dimension with smoked paprika or a dash of chipotle powder.
- Try herbs like mint or cilantro for a unique signature.
How to Use Fresh Chili Harissa
This fiery paste is a versatile flavor-booster. Here’s how you can use it:
- As a condiment for grilled or roasted meats—lamb, chicken, beef, or seafood.
- In stews and tagines for an aromatic, spicy backbone.

- Tossed with roasted vegetables or potatoes for an addictive side.

Tips and Troubleshooting
- Adjust the oil: More oil makes a smoother, Saucy harissa; less keeps it dense and intense.
- Watch the salt: The flavor intensifies as harissa sits, so season cautiously, especially if your intended use is as a finishing condiment.
- Safety note: Harissa made with fresh ingredients is perishable. Always refrigerate and use within a week, topping with extra oil to shield from air.
- Experiment: Try blending in charred tomatoes, shallots, or even nuts for a twist.
