This Creamy Southern Spaghetti Bake is the kind of dish that shows up at family tables and potlucks and gets immediately claimed as someone’s new favorite. I found this combination years ago when I wanted to combine two of my comfort-food go-tos — baked pasta and a creamy ranch chicken filling — into one pan. The result is cozy, filling, and extraordinarily forgiving: tender shredded chicken, a lush cream cheese and sour cream base brightened with ranch seasoning, and plenty of cheddar melted into every forkful. It’s flavorful without being complicated, and the crispy bacon on top gives a textural pop that makes everyone smile.

I usually put this together on Sunday afternoons when I want an easy dinner that will deliver leftovers for the week. The scent of baking cheese and bacon often brings neighbors to the table; one time my older son arrived home from practice early just because he could smell it through the door. The texture is rich and creamy thanks to softened cream cheese and sour cream, while the spaghetti keeps things familiar for kids and adults alike. This is a dish that performs well at gatherings and is hearty enough for a family dinner—simple to prepare, but always impressive on the plate.

Ingredients

• Spaghetti (12 ounces): Use standard dry spaghetti; look for 100% durum semolina for the best texture when baked. Boil until just al dente so it holds up in the oven without becoming mushy.
• Cooked shredded chicken (2 cups): Rotisserie chicken is my shortcut of choice — juicy and flavorful — but leftover roasted chicken or poached breasts work equally well.
• Cream cheese (8 ounces): Bring to room temperature before mixing to avoid lumps. Full-fat yields the creamiest result; brands like Philadelphia provide consistent results.
• Cream of chicken soup (10.5 ounces): Adds savory body. If you prefer less sodium, use a low-sodium variety and adjust seasoning to taste.
• Sour cream (1 cup): Adds tang and silkiness. Light versions will work but expect slightly less richness.
• Ranch seasoning packet (1 ounce): The flavor backbone of the bake; you can use homemade ranch seasoning if you want to control salt.
• Garlic powder (1 teaspoon) & Black pepper (1/2 teaspoon): Simple aromatics that lift the creamy sauce without overpowering.
• Shredded cheddar cheese (2 cups, divided): Sharp or medium cheddar both work; reserve 1/2 cup for topping so it melts and browns beautifully.
• Grated Parmesan (1/2 cup): Adds salty, umami depth—freshly grated gives the best flavor.
• Bacon (6 slices, cooked and crumbled): Fry until crisp and crumble. The bacon adds texture and a smoky contrast to the creamy filling.
• Parsley (2 tablespoons, optional): Bright finish—flat-leaf parsley chopped fine to garnish and cut the richness.

Instructions

Preheat and prepare the dish: Preheat the oven to 350°F. Grease a 9×13-inch baking dish with butter or nonstick spray so the casserole releases cleanly after baking. A metal or ceramic pan both work; ceramic holds heat well for serving. Cook the pasta: Bring a large pot of salted water to a boil and cook the spaghetti until just al dente—usually 8 to 9 minutes for standard dry spaghetti. Drain well and toss with a splash of oil to prevent sticking while you prepare the sauce. Make the cream base: In a large mixing bowl, beat the softened cream cheese until smooth. Stir in the cream of chicken soup, sour cream, and the 1-ounce ranch packet until the mixture is uniform. Add the garlic powder and black pepper and taste for seasoning. Combine filling ingredients: Fold in the shredded chicken, 1½ cups of the shredded cheddar, the grated Parmesan, and the drained spaghetti. Mix gently until the pasta is evenly coated; avoid overmixing to keep the texture intact. Assemble the casserole: Transfer the mixture to the prepared 9×13 baking dish and spread evenly. Sprinkle the remaining 1/2 cup cheddar over the top, then scatter the crumbled bacon evenly for a crisp finish once baked. Bake covered and finish uncovered: Cover the dish with foil and bake at 350°F for 25 minutes to allow the center to heat through. Remove the foil and return to the oven for 10–15 minutes, or until the top is bubbly and golden. Let rest 5–10 minutes before serving so it sets.

Storage Tips

Store leftovers in an airtight container in the refrigerator for up to four days. If you plan to freeze, portion into meal-sized containers or cover the entire 9×13 pan tightly with plastic wrap followed by foil. To reheat refrigerated portions, warm in a 350°F oven for 15–20 minutes or microwave until heated through; add a splash of milk or a dollop of sour cream if the texture tightens. For previously frozen dishes, thaw overnight in the refrigerator and bake at 350°F for 25–30 minutes until hot in the center.

Ingredient Substitutions

If you want to lighten the bake, swap half-and-half for sour cream and use reduced-fat cream cheese, though the texture will be slightly less rich. For a gluten-free version, use a gluten-free spaghetti and substitute a condensed gluten-free cream soup or a homemade roux-based chicken sauce. To make it vegetarian, omit the chicken and bacon and add sautéed mushrooms, spinach, or roasted vegetables; use vegetable-based condensed soup. For lower sodium, choose low-sodium canned soup and rinse the chicken or use fresh-cooked chicken with no added salt.

Serving Suggestions

Serve this as the centerpiece with a simple green salad dressed in a bright vinaigrette to cut through the richness. A side of steamed green beans or roasted Brussels sprouts pairs well for a balanced plate. At potlucks, set out hot sauce, sliced green onions, and extra grated Parmesan so guests can customize their portions. For a cozy family dinner, serve with buttery garlic rolls to sop up the creamy sauce.

Cultural Background

While not a traditional Southern heirloom, this style of baked pasta borrows from Southern preferences—creamy, cheese-forward dishes and the use of convenience ingredients like canned cream soup and ranch seasoning. Dishes that combine canned soups with meats and starches became popular in mid-20th-century American home cooking for their convenience and satisfying flavors, evolving into the casserole traditions people still cook today.

Seasonal Adaptations

In cooler months, add roasted root vegetables like butternut squash or sweet potato for heartier comfort; in summer, swap the chicken for grilled rotisserie-style pieces and add fresh chopped tomatoes and basil just before serving. For holiday gatherings, fold in some cooked, diced ham and replace half the cheddar with smoked gouda for a festive smoky twist.

Meal Prep Tips

Assemble the casserole in advance and keep it refrigerated for up to 24 hours before baking to save time on busy evenings. If you’re meal-prepping for the week, portion into individual oven-safe containers for easy grab-and-bake dinners. Label containers with the bake date and reheating instructions to streamline your weekly routine. This casserole is forgiving—just be sure to keep the pasta slightly undercooked initially so it doesn’t over-soften during reheating.

Finish with a sprinkle of fresh parsley and a few extra crumbled bacon pieces for presentation. This Creamy Southern Spaghetti Bake is a warm, generous dish that invites sharing—make it once and you’ll likely find it on repeat in your dinner rotation.
