Easy one-pot taco soup with ground beef, black and pinto beans, Rotel, corn and homemade taco seasoning. Ready in 40 minutes, with crockpot and Instant Pot options.
Heat the olive oil in a large pot over medium-high heat. Add the ground beef and onion and cook 7 to 8 minutes, breaking up the meat, until no pink remains (160°F / 71°C) and the onion is soft.
Spoon off most of the fat, leaving about 1 tablespoon in the pot.
Add the bell pepper and garlic and cook 2 minutes, until the pepper starts to soften.
Stir in the tomato paste, chili powder, cumin, smoked paprika, oregano, onion powder, salt and cayenne. Cook 60 seconds, stirring, until fragrant and the paste turns brick red.
Pour in the beef broth and both cans of Rotel with their juice. Scrape up any browned bits from the bottom of the pot.
Add the black beans, pinto beans and corn. Bring to a boil, then reduce the heat to a gentle simmer.
Simmer with the lid slightly open for 20 minutes, until the broth thickens a little.
Turn off the heat and stir in the lime juice. Taste, adjust the salt, and serve with your favorite toppings.
