How to Make Slow Cooker Herb-Crusted Chicken Fillets with Lemon Butter Sauce

1. Prepare the coating – in a shallow bowl, mix breadcrumbs, dried herbs, garlic powder, onion powder, salt, and pepper.
2. Coat the chicken – brush chicken fillets with olive oil, then press into breadcrumb mixture to coat.
3. Optional browning – for extra flavor and crunch, quickly sear the coated chicken in a skillet with 1 tablespoon butter until golden (about 2 minutes per side).
4. Slow cook – place chicken fillets in the slow cooker. In a small saucepan, melt 2 tablespoons butter with garlic, lemon juice, zest, and chicken broth. Pour sauce over chicken.
5. Cook on LOW for 3–4 hours, or HIGH for 1 ½–2 hours, until chicken is tender and cooked through.
6. Finish – just before serving, stir in the remaining 1 tablespoon butter into the sauce for extra richness. Garnish with fresh parsley.
