What model slow cooker have you got?
Right now, this minute, in my kitchen I have 3 slow cookers on the go. 2 x Morphy Richards Sear and Stew and one Cooks Professional triple pot.
I am not a Professional, just a very enthusiastic slow cooker fan!
I don't use the Sear and Stew on the hob to brown anything. I could, they are metal inner pots and designed to do this.
Put non green veg and potatoes on the bottom, place raw chicken thighs on top. Pour over hot stock. On high while you are out at work, turn down to medium when you get in, and place the handle of a tea spoon under the lid, resting on the pot, to act as a vent and reduce to a thicker gravy. An hour or so.
A small whole chicken cooks meltingly well in a SC. Put in raw, breast down, drizzle olive oil over, a pinch of salt and squirt of lemon juice. Medium while at work, when you get back vent with tea spoon if not brown enough to your taste.
If you like green olives, drain a small jar of de-stoned variety, and tip over above chicken when you first put in pot. They cook in the olive oil and are super moreish
Meatballs, sausages, fish in paper bags etc cook in 1 1/2 - 2 hours in a pre-heated pot. Meatballs and sausage need turning to brown all over.
Dumplings are super fluffy. About 30-45 min into pot after you get home to your casserole. Just one bowl and a spoon to mix up. Add cheese or herbs, use mixing spoon to drop dumpling into casserole and quickly get the lid back on. On High.
Soup is wonderful. Add mini pasta shapes last 45 mins.
Ooh and curry. Meat or veg. Hot or mild. Tomato or creamy. Thousands of recipes online.
I use 5 times a week usually.
