Step 1: Roast the Red Peppers : Preheat oven to 450°F (230°C). Place whole red peppers on a baking sheet and roast for 20 minutes, turning occasionally, until the skin is charred and blistered. Transfer peppers to a bowl, cover with plastic wrap, and let steam for 10 minutes. Peel off skins, remove seeds, and roughly chop.
Step 2: Blend the Hummus : In a food processor, combine chickpeas, roasted red peppers, tahini, garlic, lemon juice, cumin, and salt. Blend until smooth, scraping sides as necessary. Gradually add olive oil and water until desired creamy consistency is reached.
Step 3: Serve and Garnish : Transfer hummus to a serving bowl. Drizzle with olive oil and sprinkle smoked paprika, parsley, or toasted pine nuts if desired. Serve with warm pita bread or vegetable sticks.
