This savory black bean garlic paste turns simple pantry ingredients into a bold, deeply flavored sauce for noodles and vegetable stir-fries. Slow-cooked garlic, soy sauce, palm sugar, and warm five-spice give it a rich, umami-packed finish that's great for meal prep.
Rinse the black turtle beans, then place them in a Dutch oven with 5 cups of water, the salt, and baking soda. Bring to a boil, cover, and simmer for 45 to 60 minutes, or until the beans are very tender. Reserve about 1 cup of the cooking liquid, then drain the beans.

Pour the neutral oil into a small saucepan and add the garlic cloves and dried Thai chilies. Cook over low heat for 12 to 15 minutes, stirring occasionally, until the garlic is soft and lightly golden. Remove the chilies if they darken too quickly.



Transfer the cooked beans to the garlic oil. Add the chopped onion, ginger, and Chinese five-spice, then cook for 2 to 3 minutes until fragrant.


Stir in the rice cooking wine, soy sauce, and palm sugar. Simmer for 10 minutes, stirring occasionally, until the mixture is glossy and the onion has softened.


Stir the cornstarch with a little cold water to make a slurry, then add it to the bean mixture. Cook for 2 to 3 minutes more, until slightly thickened. Let the mixture cool for a few minutes, then pulse in a food processor until mostly smooth but still a little chunky.



For a quick noodle bowl, cook the rice noodles in 2 cups of water until tender. Spoon in about 1 teaspoon of the black bean paste and a splash of the reserved bean cooking liquid, then stir well to coat the noodles and lightly season the broth.


For a heartier stir-fry, cook 1/4 cup of the black bean paste in a wok with the daikon, potato, zucchini, cucumber, and remaining onion for 2 to 3 minutes. Add some reserved bean cooking liquid, cover, and steam until the vegetables are tender. Thicken with a little extra cornstarch slurry if needed, then top with tofu seared in sesame oil and serve over noodles or rice.


Store the black bean paste in a sealed container in the refrigerator for up to 1 week; do not keep garlic-in-oil mixtures at room temperature. If you want a smoother sauce, blend the paste longer. Use store-bought Chinese five-spice for convenience, and adjust the chilies to control the heat.
