Make the chili crisp: In a small heatproof bowl, add the onion, garlic, red pepper flakes, paprika, and ½ teaspoon salt and stir to combine.
In a small saucepan, heat the oil over medium heat until it shimmers, about 2 minutes.
Pour the oil over the spice mixture, then let cool completely, about 30 minutes.
Transfer the mixture to a glass jar. It can be stored in the refrigerator for up to 3 months.
Make the chili-crisp chickpeas: In a large bowl, stir together the chickpeas, chili crisp, 1 tablespoon oil, 1 teaspoon lemon juice, sweet paprika, and ½ teaspoon salt until the chickpeas are evenly coated. Set aside or store in the refrigerator until ready to serve.
Make the hummus: In a food processor with the knife blade attached, add the chickpeas, garlic, tahini, lemon juice, 3 tablespoons oil, and 1 teaspoon salt. Process until smooth and creamy, about 2 minutes, scraping down the sides of the bowl as needed. With the food processor running and the cover of the feed tube removed, add 1 tablespoon of ice water at a time until a consistency you like.
Transfer the hummus to a serving bowl and top with chili-crisp chickpeas.
