Slow Cooker Chipotle Enchilada Sauce

16-oz chicken broth
32-oz fire roasted tomatoes
2 onions, diced
5 cloves garlic
4 chipotle peppers in adobo sauce (seeds removed)
2 tbsp adobo sauce (from the the can of peppers)
1 1/2 tbs cumin
1 tsp chilli powder
1 tsp salt
pinch of sugar

Slice open the chipotle peppers and remove the seeds. Place the tomatoes, onion, garlic, chipotle peppers, adobo sauce, cumin, chilli powder, salt, sugar and chicken broth in your slow cooker. Cook on low for 6-8 hours, or high for 3-4 hours. Remove the chipotle peppers, then  using an immersion blender, puree the sauce until smooth. You can also use your blender to puree the sauce.  Now get ready for the best enchiladas ever! Store the sauce in glass mason jars in the fridge. Can be kept in the fridge up to 2 weeks, or will keep in the freezer for up to 4 months.

Recipe Note: This sauce is a little spicy, so if you want to tame it down for little mouths, reduce the amount of chipotle peppers and adobo sauce you use. 

FREEZER DIRECTIONS: Cool the sauce completely. When it's completely cool, ladle into quart sized freezer bags which are placed standing up in a glass measuring cup. Gently squeeze the air out. Lay flat and freeze. Thaw for 24 hours and reheat on the stove top or by microwaving slowly. You can also reheat by placing the the frozen enchilada sauce in your slow cooker. Turn on low and cook until heated through.
