Preheat and prep: Heat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with butter or avocado oil.
Soften the cream cheese: In a large bowl, add the softened cream cheese, heavy cream, and mayonnaise.
Beat or whisk until smooth and creamy.
Add the seasonings: Stir in ranch seasoning, garlic, onion powder, a pinch of salt, and black pepper. Taste and adjust seasoning if needed. The sauce should be flavorful at this stage.
Fold in the chicken: Add the shredded or diced chicken and toss to coat evenly in the ranch mixture.
Add veggies and bacon: If using broccoli, fold it in now along with half of the crumbled bacon and half of the green onions.
Cheese it up: Mix in half of the shredded cheese until it’s evenly distributed.
Assemble the bake: Transfer the mixture to the prepared baking dish.
Smooth it into an even layer. Top with the remaining shredded cheese.
Bake: Place in the oven and bake for 18–22 minutes, or until the cheese is melted, bubbly, and lightly golden at the edges.
Finish and garnish: Remove from the oven. Sprinkle the remaining bacon and green onions over the top.
Let it rest for 5 minutes before serving so it sets slightly.
Serve: Spoon into bowls or plates. Pair with a crisp side salad or roasted asparagus for a balanced, low-carb meal.
