Preheat your oven to 375°F (190°C) and grease a baking dish lightly

Heat a skillet over medium heat and cook bacon until crispy, then crumble and set aside

In the same skillet, add olive oil and lightly sear chicken pieces for 3–4 minutes (optional step for extra flavor)

In a large bowl, combine softened cream cheese, sour cream, and mayonnaise

Whisk until smooth and creamy with no lumps

Add garlic, garlic powder, onion powder, salt, and pepper to the mixture

Stir until seasoning is evenly distributed

Fold in half of the shredded cheddar and mozzarella cheese

Add diced jalapeños and half of the crumbled bacon to the mixture

Add chicken to the bowl and mix until fully coated in the creamy sauce

Transfer the mixture evenly into the prepared baking dish

Spread it out evenly using a spatula

Sprinkle remaining cheddar and mozzarella cheese over the top

Add remaining bacon and extra jalapeño slices for garnish

Bake for 25–30 minutes until bubbly and golden on top

Broil for 2–3 minutes for a crispy cheesy crust

Remove from oven and let rest for 5–10 minutes

Garnish with green onions if desired
