Season the chicken. Pat chicken dry and season both sides with salt, pepper, and onion powder. This simple base seasoning helps build flavor.
Layer the crockpot. Add chicken broth to the crockpot.
Place the chicken on top. Scatter the cream cheese cubes around the chicken.
Add flavor boosters. Sprinkle in garlic, Italian seasoning, and red pepper flakes. Add chopped artichoke hearts.
Drizzle with olive oil or dot with butter.
Cook low and slow. Cover and cook on Low for 3.5–4.5 hours, or on High for 2–3 hours. You’re aiming for tender chicken that shreds easily and reaches 165°F internally.
Stir in dairy and greens. Shred or slice the chicken in the crockpot. Add heavy cream, Parmesan, and mozzarella.
Stir until the cheeses melt. Fold in spinach and let it wilt, 5–10 minutes. If using frozen spinach, squeeze out excess water first.
Adjust and finish. Add lemon juice if using, then taste and adjust salt and pepper.
If the sauce is too thick, splash in more broth or a little cream. If it’s thin, leave the lid off for 10–15 minutes to reduce.
Serve your way. Spoon over cauliflower rice, roasted broccoli, or sautéed zucchini. Garnish with parsley for a fresh finish.
