Using the saute function, warm 2 tablespoons olive oil on high in an Instant Pot. When it’s hot, stir in onion, poblano chile, red bell pepper, garlic and jalapeno, and cook, stirring occasionally, until tender (5 to 7 minutes). Transfer cooked veggies to a bowl and return the pot to high heat.
Add remaining 1 tablespoon olive oil to the pot, then add the ground chicken. Cook the meat, stirring occasionally, until evenly browned (6 to 7 minutes). I like to let the chicken sit for a little bit to develop some deeper golden color, and then stir.
Stir in chile powder, cumin and coriander, and cook, stirring frequently, until aromatic (about 1 minute). Stir in tomato paste and cook, stirring occasionally, for 2 minutes. Deglaze the pan with the beer, scraping up any brown bits off the bottom of the pan.
Add diced tomatoes, beans, salt, oregano, pepper, 1 cup of water and cooked veggies to the Instant Pot, stirring to combine. Cover and cook on high pressure for 20 minutes. Allow the pressure to release naturally (up to 10 minutes). Season to taste with salt.
To serve, ladle chili into a bowl, then top with sour cream, cilantro, sliced scallions and grated cheddar cheese.
