Slow-cooking chicken breasts is our favorite meal prep hack: You throw several in on a Sunday morning, let them go, and then shred up the chicken for meals throughout the week. We love keeping things simple with potatoes, rosemary, and lemon.
- In a slow-cooker, toss onion, potatoes, and lemon slices together with olive oil. Spread into an even layer.
- In a large bowl, stir together salt, pepper, and garlic powder. Add chicken breasts and toss to coat evenly.
- Place chicken in a single layer above the onion and top with rosemary sprigs.
- Cook on low for about 4 hours, until chicken is cooked through and potatoes are fork tender.
