Set Instant Pot to saute. When it says HOT, add oil.
Add ground beef, onions and garlic to pot. Cook until meat is browned, stirring to break up meat. Season with salt, pepper, thyme and Worcestershire sauce as it is cooking.
Add tomato paste, water and beef base. Stir to scrape up any bits stuck to the bottom of the pot. Add elbows. Press cancel to stop Saute.
Lock lid in place and seal valve. Cook on high pressure for 4 minutes. (Cook time may vary with the kind of pasta you choose to use). Quick release the pressure. Stir in half of the cheese. Serve remaining cheese on the side.
This is our favorite recipe for chili. If I don’t have any chorizo, I just use 2 lb. of ground beef and increase the paprika and cumin to 2 T. each. Some of you might think it odd to add the cocoa powder or chocolate chips. However, this adds a richer taste and color to the finished product.
Rinse black beans. Put in pot and cover well with water. Bring to a boil. When the water boils, turn the pot off and let set for 1 hour. Drain beans, cover with fresh water and continue cooking until tender. Add to chili when the beans are tender.
While beans are soaking, brown beef and chorizo with onions, sweet pepper, garlic, and oil in a Dutch oven.
Add remaining ingredients (except black beans) and simmer for a couple of hours. Add water as needed for the consistency that you desire. Add black beans when they have finished cooking. This is even better if made the day before and reheated.
