Equipment Needed
4–6 quart slow cooker
Cutting board and knife
Spoon or spatula

Step-by-Step Instructions
Step 1: Add the Ground Beef
Start by placing the raw ground beef directly into the bottom of your slow cooker. Break it up with your hands or a spoon so it’s in small, even pieces. This helps it cook evenly and blend better with the other ingredients.
There’s no need to brown the beef first unless you want to reduce fat. This recipe is designed to be as easy as possible.
Step 2: Add the Onion
Sprinkle the finely chopped onion evenly over the beef. As the chili cooks, the onion softens and releases its natural sweetness, adding depth to the overall flavor.
Step 3: Add Tomatoes and Beans
Pour in the diced tomatoes with their juices and the chili beans with their sauce. Don’t drain anything—the liquid is essential for building the chili base and keeping it from drying out.
Step 4: Season Everything
Sprinkle the chili seasoning packet evenly over the top. Using a spoon, gently stir everything together until the beef, beans, tomatoes, and onions are well mixed.
Try not to over-stir at this stage. Just make sure everything is combined.
Step 5: Slow Cook to Perfection
Cover the slow cooker and cook:
On LOW for 6–8 hours, or
On HIGH for 3–4 hours
If you’re home, give it a stir once or twice during cooking. Break up any larger pieces of beef and let the flavors continue to develop.
Step 6: Taste and Serve
Once the chili is done, taste it. Add a pinch of salt or a little extra chili seasoning if needed. Ladle into bowls and serve hot.
