Make sure the liner is in your Instant Pot, then hit the saute button and add the oil. When the oil's hot add the beef, cooking and crumbling it for at least three minutes.
1 tbsp canola oil, 2 lbs ground beef
Add the onion and pepper, stirring to incorporate, and continue cooking until the beef is completely browned/crumbled and the veggies have softened.
half yellow onion, 1 poblano pepper
Add the garlic and both seasoning packets, stirring to evenly combine and continue cooking for another minute.
4-5 garlic cloves, 1 1 oz pkt dry ranch seasoning mix, 1 1 oz packet taco seasoning
Drain off any excess grease, then add the remaining ingredients to the pot, and stir together until everything's evenly incorporated.
1 15 oz can black beans, 1 15 oz can corn kernels, 2 15 oz cans dark red kidney beans, 1 28 oz can crushed tomatoes, 1 10 oz can diced tomatoes with green chiles, 1 8 oz can tomato sauce, 2 cups beef broth
Add the lid, turning to close, and make sure the vent valve is set to the 'sealed' position.
Cook the chili on HIGH pressure for 12 minutes.
Allow the pressure to naturally release for 5 minutes, then carefully and quickly open the vent valve to release the remaining trapped steam.
Season with salt and pepper, if desired. Be careful if doing as taste test- it will be HOT!
Serve warm with your favorite toppings, and enjoy!
