Cook onions over medium low heat until soft. Add garlic and cook about a minute. Add spices, stir to combine and cook for another 2 to 3 minutes.

Pour sauce over the meatballs and kidney beans. Genty stir to combine until all meatballs and beans are coated. Cover, and bake at 350 degrees for one hour. Remove cover and continue to bake for an additional 15 to 20 minutes, until meatballs are at least 165 degrees fahrenheit when tested with a meat thermometer.

Tips For The Best Results
- do not thaw frozen meatballs
- if using fresh homemade meatballs, reduce the cooking time accordingly, until internal temperature reaches 165 degrees fahrenheit
- let casserole rest for a few minutes before serving
Variations
- use red or white kidney beans, black beans or Romano beans
- make them vegan by using frozen vegan meatless meatballs – follow the same directions
- use fire roasted diced tomatoes for extra flavour
- add chopped coriander or parsley

Serving Ideas
This meatball chili is perfect just as it is, or jazz it up a bit by adding freshly shredded cheese. Top it with a dollop of sour cream, sliced green onions and fresh chopped tomatoes. Serve it with crispy tortilla chips on the side, a simple side salad, or cheddar cheese biscuits.
Storage and Reheating Suggestions
- store leftovers covered in the refrigerator for up to 2 days
- reheat single servings in the microwave
- freeze cooked casserole in an airtight container for up to 4 weeks for best flavour
- to reheat after frozen, thaw in the refrigerator and reheat in 350 degree oven for about 20 minutes or until heated through

Yes. If using fresh meatballs, reduce cooking time to approximately 40 minutes covered and then 10 minutes uncovered, or until internal temperature reaches 165 degrees fahrenheit.
Although I have not done this myself, I think you could cook these in the slow cooker. Prepare the sauce as directed, add frozen meatballs and beans to slow cooker and set on low for 6 to 8 hours or hight 3 to 4 hours, until meatballs reach internal temperature of at least 165 degrees fahrenheit.
Yes, you can easily double this recipe. I would suggest baking it in a roasting pan or extra large casserole dish to accommodate meatballs in a single layer.
I used a 9 by 13 ceramic casserole dish, but any casserole dish that allows the meatballs to be arranged in a single layer is fine.
