Harissa Roasted Veggie Tacos with Garlic Yogurt: Spicy, Roasted, and Creamy
Introduction
Harissa Roasted Veggie Tacos with Garlic Yogurt are a vibrant, flavorful vegetarian dish that combines the smoky, spicy kick of harissa with tender, caramelized roasted vegetables. The creamy garlic yogurt drizzle balances the heat, creating a perfectly harmonious taco that’s colorful, healthy, and satisfying.
Ideal for weeknight dinners, casual gatherings, or plant-based meal prep, these tacos are quick to assemble and packed with layers of flavor and texture. The combination of roasted vegetables, warm tortillas, and zesty yogurt makes every bite deliciously memorable.
Why This Recipe Is Special
Harissa, a North African chili paste, brings smoky, earthy heat that pairs beautifully with roasted vegetables. Topped with a cooling garlic yogurt sauce, these tacos are balanced in flavor and texture. Unlike typical vegetarian tacos, the harissa adds a gourmet, spicy punch without overwhelming the palate.
This recipe is versatile: you can mix and match vegetables based on seasonality, and swap yogurt for plant-based alternatives for a vegan version.

Step-by-Step Instructions
Step 1: Prepare the Vegetables
Preheat oven to 425°F (220°C). In a large mixing bowl, combine sliced bell peppers, zucchini, red onion, and cauliflower. Toss with olive oil, harissa paste, smoked paprika, salt, and pepper until evenly coated.
Step 2: Roast the Vegetables
Spread the vegetables evenly on a lined baking sheet. Roast in the preheated oven for 20–25 minutes, tossing halfway through, until tender and slightly caramelized.
Step 3: Prepare the Garlic Yogurt
In a small bowl, whisk together Greek yogurt, minced garlic, lemon juice, and salt until smooth. Adjust seasoning to taste.
Step 4: Warm the Tortillas
Warm tortillas in a dry skillet or wrap in foil and heat in the oven for 3–5 minutes until soft and pliable.
Step 5: Assemble the Tacos
Place a generous portion of roasted vegetables on each tortilla. Drizzle with garlic yogurt, sprinkle with fresh cilantro, and add optional toppings like avocado slices, pickled red onions, or crumbled feta. Serve with lime wedges on the side.
Serving Idea: Serve alongside a light salad or grain-based side for a complete meal.
Tips for Best Results
- Cut vegetables into uniform sizes to ensure even roasting.
- Roast at high heat for caramelized edges and deep flavor.
- Adjust harissa paste according to your preferred spice level.

Common Mistakes and How to Fix Them
- Vegetables undercooked: Roast at high heat and check doneness; toss halfway through for even cooking.
- Vegetables too spicy: Reduce harissa or drizzle extra yogurt to balance heat.
- Yogurt too thick: Thin with a small splash of water or milk if needed.
- Tortillas dry or cracked: Warm gently and wrap in foil to maintain pliability.
