Instant Pot Chili Mac and Cheese
- 1 Tbsp. olive oil
- 1 lb. ground beef
- ½ onion chopped
- 1 Tbsp. minced garlic
- 2 Tbsp. chili seasoning mix
- 1 14 oz. can diced tomatoes
- 5 cups beef broth
- 1 cup milk
- 1 15.5 oz. can pinto beans drained
- 16 oz. boxed pasta
- 2 cups shredded cheddar cheese
- ½ 3.5 oz. can tomato sauce small can
- Salt and pepper to taste
- Set your Instant Pot to saute mode. Once hot, add 1 Tbsp. olive oil. Allow the oil to heat, then add in ½ a chopped onion and 1 Tbsp. minced garlic. Cook down for 2-3 minutes until soft.
- Add 1 lb. ground beef to the pot and cook until browned, breaking down as the beef cooks. Allow it to sear a little on one side before you start to break it up, for best results.
- Once beef browns, add 2 Tbsp. chili seasoning mix plus salt and pepper to taste, then pour in 1 can drained pinto beans and 5 cups beef broth. Finally, add ½ small can tomato sauce, diced tomatoes and 16 oz. uncooked pasta. Make sure the pasta is submerged!
- Lock the lid into place and cook on high pressure for 5 minutes. Quick release when the time is up. To finish the dish, mix in 1 cup milk and 2 cups shredded cheddar cheese. Stir well until fully mixed through.
