Chicken Bacon Ranch Casserole is that crowd-pleasing weeknight wonder I lean on whenever I crave comfort with minimal effort but maximum flavor. It is creamy cheesy and loaded with savory goodness the whole family loves to dig into the bubbling golden pan right out of the oven.
It is the casserole that got my picky eaters genuinely excited for leftovers. The first time I baked this during a busy holiday week my kitchen was filled with irresistible aromas everyone was hovering with plates ready before it even hit the table.
Ingredients
- Penne pasta: cooked al dente so it holds its shape and texture
- Sour cream: for richness and tangy creaminess choose full fat for best results
- Ranch seasoning mix: adds bold herby flavor look for a classic packet with minimal fillers
- Cooked shredded chicken: use rotisserie for flavor depth and convenience or poach boneless breasts
- Homestyle Alfredo sauce: brings comforting creaminess jarred is fine but look for one with real cheese
- Cream of chicken soup: binds it all together and adds savory undertones opt for a low sodium version if you want more control
- Shredded mozzarella cheese: provides gooey melt plus an irresistible golden topping
- Bacon: cooked crisp and chopped for smoky bites real bacon is best but pre-cooked will work in a pinch
- Chopped green onions: for a fresh sharp lift look for vibrant green stems that are firm and unbruised
Instructions
- Prepare the Pasta:
- Cook the penne just to al dente according to package directions. Drain well. Cooking to al dente ensures the pasta keeps its shape in the bake and absorbs the creamy sauce perfectly.
- Mix the Filling:
- In a large mixing bowl blend the cooked pasta with the sour cream ranch mix shredded chicken Alfredo sauce cream of chicken soup and one cup mozzarella. Stir gently but thoroughly so every bite gets coated in creamy ranch goodness.
- Fill the Casserole Dish:
- Grease a nine by thirteen inch dish with butter or nonstick spray to prevent sticking. Spread the mixture evenly using a spatula to push it into corners for even baking.
- First Bake Covered:
- Cover the dish tightly with foil to trap steam and bake in a preheated three hundred fifty degree oven for twenty five minutes. This melds the flavors and starts the melting process.
- Add Toppings and Finish Baking:
- Take off the foil and scatter the rest of the mozzarella plus the cooked bacon and green onions over the top. Bake uncovered for another twenty minutes until the cheese is bubbling and turns a deep golden color.
- Rest Before Serving:
- Let the casserole stand for five to ten minutes out of the oven so it firms up and slices cleanly. This step makes serving much easier and keeps the cheese from sliding everywhere.

I love how the smoky bits of bacon cut through the creamy layers. The first time my dad tasted it he asked for seconds before I could even pour the drinks. The combination of crispy bacon with gooey cheese is the best part we always sneak a few extra crumbles on top.
Storage Tips
Let the casserole cool completely before covering and refrigerating. It keeps well for up to three days in the fridge and actually tastes even richer on day two. To reheat cover the dish loosely with foil and warm at three hundred twenty five degrees until hot and bubbly. If you have leftovers portion them into airtight containers for easy grab and go lunches.
Ingredient Substitutions
Most short pasta shapes work if you do not have penne. Try rotini or fusilli for the same sauce-catching effect. If you are out of ranch mix blend a mixture of garlic powder onion powder dried dill and a pinch of salt. For a lighter version use half the bacon or sub in turkey bacon.
Serving Suggestions
This casserole is a star on its own but I always pair it with a simple green salad or some roasted broccoli to balance the richness. Warm crusty bread is great for mopping up all that creamy sauce. Add a side of fresh chopped tomatoes for a juicy touch.
Cultural and Seasonal Adaptations
Chicken bacon ranch is a classic combo born from Midwest family kitchens. When the weather cools I add chopped steamed broccoli or blanched green beans for extra color and veg. In summer a spoonful of fresh diced tomatoes or thinly sliced zucchini layers in subtly.

The creamy bacon and ranch combination is a hit every time I serve it. Leftovers never last long in our house!
