Season the chicken. Pat the chicken dry and sprinkle with salt, pepper, garlic powder, onion powder, and smoked paprika.
Layer the crockpot. Place the chicken in the slow cooker. Pour in the chicken broth.
Scatter the cream cheese cubes on top.
Add heat and flavor. Sprinkle in the diced jalapeños. If you want a bolder kick, reserve some seeds and add them now or at the end.
Cook low and slow. Cover and cook on Low for 4–5 hours or High for 2.5–3 hours, until the chicken shreds easily with two forks.
Shred and enrich. Shred the chicken in the pot. Stir in the heavy cream, cheddar, and Monterey Jack.
Mix until the cheeses melt and the sauce is creamy.
Finish with bacon. Stir in most of the crumbled bacon, saving a little for topping. Taste and adjust salt and pepper.
Serve and garnish. Spoon into bowls or over cauliflower rice. Top with remaining bacon and green onions.
Add a squeeze of lime for brightness if you like.
