Add brown rice, dried black beans, onion, corn kernels, and broth to the Instant Pot. Stir well to combine.
Next, add the salsa, cilantro, salt, and spices (ground cumin, garlic powder, chili powder, and smoked paprika). Do not stir at this stage.
Secure the Instant Pot lid and pressure cook on high pressure for 25 minutes. Do a natural pressure release for 10 minutes, then do a quick manual release of the remaining pressure.
Open the lid and mix gently. If there is excess liquid, set it back to saute for another 5 minutes. Serve warm.
Notes
Thoroughly rinse the brown rice and dried black beans before cooking to remove any debris and excess starch, ensuring a cleaner taste and better texture.
Do not stir the ingredients after adding the salsa. This technique helps prevent burn notices by keeping salsa from sticking to the bottom and allows for gradual flavor infusion.
Choose low-sodium vegetable broth to control the saltiness of the dish. Alternatively, water can be used, but vegetable broth enhances the flavor.
