Heat the Olive Oil in a large skillet on medium heat. Add the onions, cook until they begin to soften, about 5 minutes.
Add the ground turkey to the skillet. Cook for 10 mintues, stirring occasionally, until the turkey meat begins to brown.
Add the garlic and cook for 30 seconds.
Slow Cooker
Transfer the meat, onions, and garlic to a slow cooker. Add the remaining ingredients to the slow cooker. Stir to combine the ingredients.
Cover the slow cooker, and cook on low for 8-10 hours or on high for 4-6 hours.
Stovetop
Add the Hatch Chiles and diced tomatoes with juices to the pot with the meat, onions, and garlic. Stir to combine and bring to a simmer.
Next, add the spices and tomato paste.
Simmer the chili, uncovered for 30 minutes, stirring occasionally. (Add an extra 10-15 minutes to really deepen the flavor!)
Serving
When cooking is complete, serve the chili in bowls topped with your favorite toppings!
Notes
The cooking time listed for this recipes is for the stove top version. Plan on 8 hours from start to finish if using the slow cooker.
Hatch chiles come in mild, medium or hot. I have made this chili with mild and medium; personally I prefer the medium version. If you have mild on hand but want the chili a bit hotter, you can increase the dried spices, especially chili powder.
