Preheat and prep: Heat your oven to 375°F (190°C). Lightly spray a 9x13-inch baking dish with olive oil.
Cook your bacon: Crisp the bacon in a skillet and set aside to cool.
Crumble into small pieces. If using turkey bacon, cook until nicely browned for best flavor.
Soften and mix the base: In a large bowl, whisk the softened cream cheese, Greek yogurt, chicken broth, and ranch seasoning until smooth. Stir in garlic powder, onion powder, and black pepper.
Add the protein and veg: Fold in the shredded chicken, half the green onions, and half the cheddar.
If using riced cauliflower or quinoa, mix it in now. Add optional veggies if you like.
Layer and top: Spread the mixture evenly in the baking dish. Sprinkle the remaining cheddar and most of the crumbled bacon over the top (save a little for garnish).
Bake: Place on the center rack and bake for 20–25 minutes, until the edges bubble and the cheese is melted and golden in spots.
Finish and rest: Remove from the oven.
Let it rest for 5–10 minutes to set. Garnish with the remaining bacon and green onions. Taste and adjust salt if needed.
Serve: Scoop generous portions.
It pairs well with a crisp salad, roasted green beans, or garlic asparagus.
