Chop onions, garlic, spinach, and artichokes before assembling the stew. Cube cream cheese so it melts evenly later. Having ingredients ready makes the process smooth and quick.
Place chicken, broth, onion, garlic, artichokes, and seasonings into the cooker. Stir gently to distribute flavors. Place cream cheese cubes on top so they melt slowly while cooking.
Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours. Avoid opening the lid often since heat escapes and cooking slows down. The chicken becomes tender and flavorful.
Remove cooked chicken once tender and shred it using two forks. Return shredded chicken to the pot so it absorbs the creamy sauce. This step ensures balanced texture in every bite.
Stir in spinach and cornstarch slurry during the final 20 minutes. Spinach wilts quickly and blends smoothly. The slurry thickens the stew into a creamy consistency.
Stir in yogurt and shredded cheese before serving. Taste and adjust seasoning if necessary. Serve hot while the stew is creamy and comforting.
