In a small bowl, mix salt, paprika, pepper, and oil to form a paste; spread evenly over each piece of chicken.
In a 5- to 6-quart slow cooker, place onion slices. Arrange chicken over onion. Separate garlic into cloves; do not peel cloves. Place garlic cloves around chicken.
Cover; cook on Low setting 7 to 8 hours.
With a slotted spoon, remove chicken, onion and garlic from slow cooker; place on serving platter. Squeeze garlic cloves to use cooked garlic on mashed potatoes, vegetables or bread.
Notes
Slow-Cooker Twenty-Garlic Chicken Dinner
Spend 15 minutes in the morning, and this classic dish is ready at dinnertime.
This sounds like a lot of garlic, but the garlic flavor dissipates during the long cooking. Plan to serve the cooked garlic with another part of the meal. It is delicious on bread or mashed potatoes.
