Prep the bacon: Cook the bacon in a skillet over medium heat until crisp.
Transfer to a paper towel-lined plate and crumble. Reserve 1 tablespoon of bacon fat in the pan or use oil.
Roast the veggies: Heat the oven to 425°F (220°C). Toss broccoli with olive oil, salt, and pepper on a sheet pan.
Roast for 15–18 minutes until lightly charred and tender.
Season the chicken: Pat the chicken dry. Toss with half the ranch seasoning, a pinch of salt, and pepper.
Sear the chicken: Heat the skillet with bacon fat or oil over medium-high. Add chicken in a single layer.
Cook 6–8 minutes, stirring once or twice, until browned and cooked through. Transfer to a plate.
Build the sauce: Reduce heat to medium. Add garlic and sauté 30 seconds.
Whisk in chicken broth, scraping up any browned bits. Add cream cheese in chunks, stirring until smooth and creamy.
Add ranch and dairy: Stir in the remaining ranch seasoning and Greek yogurt or sour cream. Simmer on low for 1–2 minutes until slightly thickened.
Combine: Return chicken and any juices to the pan.
Stir to coat. If using cheese, add it now and let it melt. Fold in most of the crumbled bacon, saving some for topping.
Taste and adjust salt and pepper.
Finish and brighten: Off the heat, add chopped parsley or chives and a small squeeze of lemon if you like. This keeps the sauce from tasting flat.
Assemble meal prep: Divide rice or quinoa (if using) among 4 containers. Add chicken with sauce and roasted veggies.
Top with remaining bacon and extra herbs.
Cool and store: Let containers cool uncovered for 20–30 minutes, then seal and refrigerate.
