I have made a lovely chicken tagine and have one called Chicken Tangier that I am going to try soon.
Chicken tagine is basically:
Skinless chicken thighs (maybe 6 or so) or other chicken bits
2 chopped onions
A good few cloves of garlic, crushed
A good two handfuls of chopped dried apricots
Chicken stock -- about half a pint
Tin of chopped tomatoes
Spices 1 teasp each cinnamon, ginger (or fresh ginger finely chopped), cayenne or pepper flakes (maybe a bit less/to taste), cumin, coriander plus fresh coriander chopped, salt and pepper (less than 1 teasp pepper unless you love pepper)
Chickpeas
Honey
Olive oil
Optional: 2 chopped and diced carrots and 2 preserved lemons.
Brown chicken, onions and garlic in a pan and add to crockpot.
Add the rest of the ingredients except tin of chickpeas.
Stir, cover, cook on high 3-4 hours or low about 6 hours.
Add chickpeas for last hour.
If you want to thicken the sauce, add tomato paste, stir in and cook until sauce thickens. You could stir in some fresh coriander to serve too.
I also found it's possible to make cakes in the crockpot. Spent last night and a lot of today munching on a lovely lemon cake, slightly too browned on one part of the bottom but otherwise lovely and the DDs were all excited about baking it. During the week last week we made gingerbread.
There are a lot of recipes on the internet. Best method is to place a wide piece (4-5") of folded over tin foil into the crockpot and hanging out the sides to act as a handle and lifter, and bake the cake in a greased and wax paper lined deep ovenproof dish what fits into the crockpot, with the crockpot lid covering it all. My recipe calls for baking on high 1.5 to 1.75 hours but I found turning it down to low for the last 30 minutes prevented burning from getting out of hand.
