Best Substitutes for Harissa
Harissa is a North African chili paste that brings three layers of complexity: heat from chilies (typically 2-8 Scoville heat units per teaspoon), smoky depth from roasted peppers, and aromatic warmth from spices like cumin, coriander, and caraway. Store-bought versions range from 15-30% chili content with olive oil, garlic, and salt making up the base. The paste consistency means it coats ingredients and distributes evenly, unlike dry spices that can clump. When substituting, you need to match the heat level, the moisture content, and those earthy background notes. A straight chili powder swap misses the complexity entirely.
Best Overall Substitute
Sriracha at a 3:4 ratio (3 teaspoons sriracha for every 4 teaspoons harissa). It matches the paste consistency and heat level closely, though it leans sweeter and more garlicky than traditional harissa. The vinegar tang approximates the fermented flavor some harissa varieties have.
All Substitutes
Sriracha
3:4 ratio (3 tsp sriracha per 4 tsp harissa)Sriracha delivers similar heat (1,000-2,500 Scoville units vs harissa's 1,000-5,000) and the same paste consistency that coats food evenly. The garlic and sugar content is higher, so it tastes sweeter and less earthy. The vinegar provides tang that mimics fermented harissa varieties. Works directly in marinades and sauces without texture adjustments.
Chipotle paste
1:1 substitutionChipotle paste matches harissa's smoky intensity and paste texture perfectly. Made from smoked jalapeños, it provides 2,500-8,000 Scoville units (slightly hotter than most harissa). The smokiness is more prominent than harissa's roasted pepper notes. Mix with 1/4 teaspoon cumin per tablespoon of paste to approximate harissa's spice blend.
Tomato paste + paprika + cayenne blend
2 tbsp harissa = 1 tbsp tomato paste + 1/2 tsp smoked paprika + 1/4 tsp cayenne + pinch cuminThis combination builds harissa's complexity from scratch. Tomato paste provides the thick, coating texture and slight sweetness. Smoked paprika adds the roasted pepper flavor without overwhelming heat. Cayenne brings the kick (30,000-50,000 Scoville units, so use sparingly). Cumin approximates the warm spice notes.
Sambal oelek
1:1 substitutionSambal oelek is pure ground chilies with salt and vinegar, delivering clean heat (1,000-2,500 Scoville units) without competing flavors. It lacks harissa's smokiness and warm spices but provides the same paste texture and straightforward chili heat. Add 1/4 teaspoon smoked paprika per tablespoon to approximate the roasted pepper notes.
Gochujang thinned with oil
1 tbsp gochujang + 1 tsp olive oil = 2 tbsp harissaGochujang provides fermented complexity and moderate heat (1,500-8,000 Scoville units depending on brand). The fermented soybean base adds umami depth that partially replaces harissa's warm spices. Thinning with olive oil creates the right consistency. The sweetness is more prominent than harissa, and the flavor profile shifts Korean rather than North African.
Aleppo pepper + tomato paste
1 tsp Aleppo pepper + 1 tbsp tomato paste = 2 tbsp harissaAleppo pepper brings moderate heat (10,000 Scoville units) with fruity, slightly smoky notes that closely match harissa's pepper profile. Tomato paste provides moisture and coating ability. This combination gets closer to authentic harissa flavor than most substitutes but requires sourcing specialty pepper. The heat level is milder than most harissa.
Cayenne + paprika + garlic powder blend
1/4 tsp cayenne + 1 tsp paprika + 1/2 tsp garlic powder + 1 tbsp olive oil = 2 tbsp harissaThis dry spice blend mixed with oil creates a harissa-like paste. Cayenne provides intense heat (30,000-50,000 Scoville units, so use less for milder results). Paprika adds pepper flavor and color. Garlic powder approximates harissa's aromatic base. The oil binds everything and creates coating consistency.
How to Adjust Your Recipe
Start with half the suggested substitute amount and taste before adding more. Heat levels vary dramatically between brands and types of chilies. In slow-cooked dishes, add harissa substitutes in the last 30 minutes to preserve flavor intensity. For marinades, let substitutes sit 15-20 minutes before using to allow flavors to meld. When using dry spice blends as substitutes, bloom them in oil for 30 seconds over medium heat to intensify flavors. Cold applications like dressings work better with paste-based substitutes than dry spice mixtures.
When Not to Substitute
Traditional North African dishes like shakshuka or tagines need authentic harissa for proper flavor balance. The fermented complexity and specific spice ratios can't be replicated. Restaurant-style harissa often contains preserved lemons, which no substitute can match. Dishes where harissa is the primary flavoring agent (like harissa chicken or harissa roasted vegetables) will taste noticeably different with substitutes. If the recipe calls for more than 3 tablespoons of harissa, consider buying the real thing.
Frequently Asked Questions
How spicy is harissa compared to other hot sauces?
Harissa ranges from 1,000-5,000 Scoville units, making it milder than jalapeños (2,500-8,000 units) but spicier than poblanos (1,000-2,000 units). It's roughly equivalent to sriracha in heat level but with deeper, earthier flavors. Store brands tend to be milder (1,000-2,500 units) while al versions can reach 8,000+ units.
Can I use hot paprika instead of harissa?
Hot paprika works as a base but needs help. Use 1 teaspoon hot paprika plus 1/4 teaspoon cayenne plus 1 tablespoon olive oil to replace 2 tablespoons harissa. The heat level matches (2,000-4,000 Scoville units) but you'll miss the garlic and complex spice notes. Add 1/4 teaspoon garlic powder and cumin to get closer.
How do I make harissa less spicy in a recipe?
Dilute with tomato paste at a 1:1 ratio to cut heat in half while maintaining texture. Adding 1-2 tablespoons of yogurt or sour cream per tablespoon of harissa neutralizes heat through dairy's casein proteins. Honey or sugar (1/2 teaspoon per tablespoon harissa) balances heat perception without removing capsaicin. Remove seeds from fresh chilies if making homemade versions.
What's the difference between rose harissa and regular harissa?
Rose harissa contains dried rose petals and rose water, adding floral sweetness to the standard chili-spice base. It's typically milder (1,000-3,000 Scoville units vs 2,000-5,000 for regular) and works better with lamb and chicken. Regular harissa substitutes work fine, but add 1/4 teaspoon honey per tablespoon to approximate the floral sweetness of rose varieties.
