Season the chicken: Pat the chicken dry. Sprinkle with salt, pepper, garlic powder, onion powder, and Italian seasoning on both sides.
Layer the slow cooker: Add chicken to the crockpot in a single layer if possible.
Scatter minced garlic and chopped artichokes over the top.
Add the creamy base: Dot the chicken with cream cheese cubes. Pour in the chicken broth. Sprinkle in the Parmesan.
If using red pepper flakes, add a pinch now.
Cook low and slow: Cover and cook on Low for 3.5–5 hours or High for 2–3 hours, until the chicken is tender and reaches 165°F.
Add the greens: In the last 20–30 minutes, stir in the spinach. If using frozen spinach, squeeze out excess moisture first. Cover and let it wilt.
Finish the sauce: Stir everything to combine, breaking up any remaining cream cheese.
Add half-and-half if you want a looser, silkier sauce. Stir in lemon juice to brighten.
Shred or slice: Shred the chicken directly in the crockpot with two forks for a dip-like texture, or slice and spoon the sauce over the top for a neater presentation.
Taste and adjust: Add more salt, pepper, or lemon to taste. Garnish with parsley if you like.
Serve: Spoon over pasta, rice, quinoa, mashed potatoes, or with crusty bread.
It’s also great in wraps.
