Preheat your oven to 375°F (190°C). Grease a baking dish with cooking spray or butter.
Season the chicken breasts with salt, pepper, and dried thyme. Set aside.
In a skillet over medium heat, cook the diced bacon until crispy. Remove from the skillet and set aside on a paper towel-lined plate to drain excess grease.
In the same skillet, add the cauliflower florets and cook for about 5-7 minutes, or until they start to soften. Remove from heat and set aside.
In a small bowl, mix together the sour cream, mayonnaise, minced garlic, half of the cooked bacon, and half of the shredded cheese.
Place the seasoned chicken breasts in the prepared baking dish. Arrange the cauliflower florets around the chicken.
Spread the sour cream mixture evenly over the chicken and cauliflower.
Sprinkle the remaining bacon and shredded cheese over the top.
Cover the baking dish with aluminum foil and bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through and the cauliflower is tender.
Remove the foil and switch the oven to broil. Broil for an additional 2-3 minutes, or until the cheese is bubbly and golden brown.
Garnish with chopped fresh parsley and a drizzle of hot sauce before serving. Enjoy your Chicken Bacon Cauliflower Bake!
