Why This Recipe Works
This recipe leans on familiar flavors that never go out of style. The ranch seasoning adds a bold punch that coats the chicken and veggies, while bacon ties it all together with a savory, smoky finish.
Cream cheese and heavy cream create a rich, velvety sauce that clings to everything without needing flour or starches. Finally, a layer of melted cheese turns the top golden and irresistible, keeping every bite indulgent but still low in carbs.
What You’ll Need
- Cooked chicken: 4 cups, shredded or cubed (rotisserie chicken works great).
- Bacon: 8 slices, cooked and crumbled.
- Broccoli florets: 3 cups, lightly steamed or blanched.
- Cauliflower rice or florets (optional): 2 cups, steamed (adds bulk without carbs).
- Cream cheese: 8 oz, softened.
- Heavy cream: 1/2 cup.
- Sour cream: 1/2 cup.
- Shredded cheese: 2 cups total (cheddar, mozzarella, or a blend).
- Ranch seasoning: 2–3 tablespoons (homemade or store-bought).
- Garlic powder: 1 teaspoon.
- Onion powder: 1/2 teaspoon.
- Black pepper: 1/2 teaspoon.
- Salt: To taste (go light if your ranch mix is salty).
- Green onions or chives: 2 tablespoons, sliced (for garnish).
- Butter or bacon fat: 1 tablespoon (for greasing the dish and extra flavor).
How to Make It
- Preheat the oven: Set to 375°F (190°C). Grease a 9×13-inch baking dish with butter or reserved bacon fat.
- Cook the bacon: Fry until crisp, then crumble.
Reserve 1 tablespoon of the fat if you can.
- Prep the veggies: Lightly steam the broccoli (and cauliflower, if using) until just tender-crisp. Drain well to avoid a watery casserole.
- Make the sauce: In a large bowl, whisk together softened cream cheese, heavy cream, sour cream, ranch seasoning, garlic powder, onion powder, black pepper, and a pinch of salt. Stir until smooth.
- Add the cheese: Fold in 1 cup of the shredded cheese to enrich the sauce.
- Combine the filling: Add the cooked chicken, broccoli (and cauliflower), and half the crumbled bacon to the bowl.
Toss to coat everything evenly in the sauce.
- Assemble: Spread the mixture in the prepared baking dish. Top with the remaining 1 cup of shredded cheese.
- Bake: Place in the oven for 18–22 minutes, until the cheese is melted and bubbling at the edges.
- Finish and garnish: Sprinkle the remaining bacon over the top. Let it sit for 5 minutes, then garnish with sliced green onions or chives.
- Serve: Spoon into bowls and enjoy hot.
Pair with a crisp side salad if you want extra greens.
Keeping It Fresh
Store leftovers in an airtight container in the fridge for up to 4 days. The flavors actually deepen by day two, making it a great meal-prep option. Reheat in the microwave in 60–90 second bursts or warm in a 300°F oven until heated through.
For freezing, portion into meal-size containers, wrap well, and freeze up to 2 months. Thaw overnight in the fridge, then reheat gently to keep the sauce smooth.
Benefits of This Recipe
- Low in carbs, high in satisfaction: You get the comfort of a cheesy casserole with none of the pasta or potatoes.
- Protein-packed: Chicken and bacon deliver staying power, helping you feel full longer.
- Great for meal prep: Makes a generous batch, reheats well, and travels easily for lunches.
- Customizable: Swap veggies, adjust heat, or change the cheeses to match your taste.
- Family-friendly: Ranch and bacon are familiar flavors that even picky eaters tend to love.
Pitfalls to Watch Out For
- Watery casserole: Over-steamed or wet veggies can release water during baking. Drain well and pat dry if needed.
- Too salty: Bacon and ranch seasoning can add a lot of salt.
Taste the sauce before adding extra.
- Grainy sauce: Cold cream cheese can clump. Soften it first and whisk thoroughly for a smooth texture.
- Overcooking: Too long in the oven can dry out the chicken. Bake just until bubbling and the cheese is melted.
- Hidden carbs: Some store-bought ranch mixes contain sugar or starch.
Check labels or use a homemade mix.
Variations You Can Try
- Jalapeño Popper Twist: Add sliced jalapeños and swap part of the cheddar for pepper jack. Finish with a sprinkle of smoked paprika.
- Buffalo Ranch: Stir 2–3 tablespoons of buffalo sauce into the cream mixture and top with blue cheese crumbles after baking.
- Spinach and Artichoke: Mix in 2 cups chopped spinach and 1 cup chopped artichoke hearts for a briny, creamy spin.
- Mushroom and Swiss: Sauté sliced mushrooms in butter and use Swiss or gruyère instead of cheddar.
- Turkey or Rotisserie Swap: Use leftover turkey or a rotisserie chicken to cut prep time.
- Dairy-Light Option: Replace half the cream with unsweetened almond milk and use a reduced-fat cream cheese. The sauce will be a bit looser but still tasty.
FAQ
Is this casserole truly keto-friendly?
Yes.
The recipe skips starchy fillers and focuses on low-carb ingredients like chicken, bacon, broccoli, cream cheese, and cheese. Check your ranch seasoning and bacon labels to avoid added sugars or starches.
Can I use raw chicken instead of cooked?
You can, but cook it first for best texture and food safety. Sauté bite-size pieces in a skillet with a little oil and salt until just done, then proceed with the recipe.
What can I use instead of heavy cream?
Use half heavy cream and half unsweetened almond milk for a lighter sauce.
Full substitutions with thin liquids may make the casserole watery, so consider adding a bit more cream cheese if you go lighter.
How do I make homemade ranch seasoning?
Mix dried dill, parsley, chives, garlic powder, onion powder, salt, black pepper, and a pinch of paprika. Start with 2 tablespoons in the sauce, then adjust to taste.
Can I make it vegetarian?
Yes, skip the chicken and bacon and use hearty low-carb veggies like mushrooms, broccoli, cauliflower, and zucchini. Add a little smoked paprika or liquid smoke for that savory depth.
What cheese works best?
Cheddar adds sharpness, mozzarella gives great melt, and Monterey Jack is a nice middle ground.
A blend of cheddar and mozzarella is dependable and melty without getting greasy.
How do I prevent the top from over-browning?
If the cheese is browning too fast, tent the dish loosely with foil during the last few minutes of baking. Remove the foil at the end if you want a little more color.
Can I assemble it ahead?
Yes. Assemble up to 24 hours ahead, cover, and refrigerate.
Add 5–10 extra minutes to the bake time if it goes into the oven cold.
