¼ cup vegetable oil
1 large yellow onion, finely chopped
Kosher salt and black pepper
3 celery stalks, finely chopped
1 green bell pepper, finely chopped
10 garlic cloves, finely chopped
1heaping tablespoon white or yellow miso paste
2 teaspoons smoked paprika
1 teaspoon sweet paprika
1 teaspoon onion powder
1 teaspoon garlic powder
½ to 1teaspoon ground cayenne, plus more to taste
½ teaspoon ground sage (optional)
1pound dried red kidney beans (no need to soak)
3 dried bay leaves
3fresh thyme sprigs or 1 teaspoon dried thyme
1 teaspoon soy sauce
Cooked rice, for serving
Sliced scallions, for serving
Louisiana-style hot sauce, for serving
Turn on the sauté setting of a 6- to 8-quart electric pressure cooker and heat the oil. Add the onion, season with salt, and cook, stirring occasionally, until limp and translucent, 6 to 8 minutes. Add the celery and bell pepper, and cook, stirring occasionally, until softened, 5 to 8 minutes. Add the chopped garlic, miso paste, smoked paprika, sweet paprika, onion powder, garlic powder, cayenne and sage (if using). Grind in a generous amount of black pepper and add ¾ teaspoon salt. Stir well to combine all the ingredients, then turn off the sauté setting.
Add the beans, bay leaves, thyme and 5½ cups water. Scrape the bottom of the pot to loosen any browned bits. Cook on high pressure until the beans are creamy, 50 minutes to 1 hour.
Turn off the pressure cooker and allow the pressure to reduce naturally for 10 minutes, then release the remaining pressure manually and open the lid. Add the soy sauce, and season to taste with salt and cayenne. Using a fork, mash some of the beans against the side of the pressure cooker to make the mixture creamy. It will continue to thicken as it sits, or you can turn on the sauté setting and let the mixture bubble for a few minutes to thicken. Discard the bay leaves and thyme sprigs. Top the beans with hot cooked rice and scallions; serve with hot sauce.
