Step-by-step overview
This is a straightforward bake: cook the spaghetti to just al dente, whisk together a creamy base of cream cheese, cream of chicken soup, sour cream and ranch seasoning, then fold in shredded chicken, Parmesan and most of the cheddar. Transfer to a 9×13 dish, top with the remaining cheddar and crumbled bacon, cover and bake until bubbly, then remove the foil to brown the top. Let it rest a few minutes so it sets and slices cleanly.
What you’ll need
- 12 oz spaghetti (use regular or whole-wheat; cook slightly under al dente)
- 2 cups cooked, shredded chicken (rotisserie chicken works well)
- 1 (8 oz) block cream cheese, softened
- 1 (10.5 oz) can cream of chicken soup
- 1 cup sour cream
- 1 (1 oz) packet ranch seasoning mix
- 1 teaspoon garlic powder
- 1/2 teaspoon black pepper
- 2 cups shredded cheddar cheese, divided
- 1/2 cup grated Parmesan cheese
- 6 slices bacon, cooked and crumbled
- 2 tablespoons chopped parsley (optional, for garnish)
Ingredient notes and swaps:
- Cream cheese: soften to room temperature or warm slightly (10–20 seconds in microwave) for easier mixing.
- Chicken: leftover roasted chicken, rotisserie, or poached breasts all work. For a shortcut, use pre-shredded rotisserie meat.
- Dairy-free: substitute dairy-free cream cheese and sour cream, and use a dairy-free cheddar alternative (texture will differ).
- Make it gluten-free with your favorite 12 oz gluten-free spaghetti.
Step-by-step instructions
- Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking dish.
- Cook the spaghetti in salted boiling water until just al dente (a minute or two shy of package directions). Drain and set aside.
- In a large mixing bowl, beat the softened cream cheese until smooth. Add the cream of chicken soup, sour cream, ranch seasoning, garlic powder, and black pepper. Stir until the mixture is uniform and creamy.
- Fold in the cooked shredded chicken, 1½ cups of the shredded cheddar, the Parmesan, and the drained spaghetti. Mix gently until every strand is coated.
- Transfer the mixture to the prepared baking dish and spread it into an even layer.
- Sprinkle the remaining ½ cup cheddar over the top, then scatter the crumbled bacon evenly.
- Cover the dish with foil and bake for 25 minutes. Remove the foil and bake 10–15 more minutes until the casserole is bubbling and the top is golden.
- Let the bake rest for 5–10 minutes before serving so it sets and slices hold together. Garnish with chopped parsley if you like.
Best ways to enjoy it
Serve this casserole warm and scoopable straight from the dish. It pairs nicely with a bright, acidic side to cut through the richness:
- A crisp green salad with vinaigrette
- Steamed green beans or roasted Brussels sprouts
- Quick pickled red onions or a tangy coleslaw
If you’re in the mood for other creamy pasta-style dishes on different nights, try a contrasting vegetarian comfort option like Creamy Gnocchi with Spinach and Feta for a lighter but still indulgent meal.
Storage and reheating tips
- Refrigerator: Store leftovers in an airtight container for 3–4 days. For best texture, reheat within that window.
- Freezer: Freeze in a tightly sealed, freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.
- Reheating: Reheat single portions in the microwave (covered) until hot throughout, or reheat a whole or half casserole in a 350°F oven, covered, until warmed to 165°F (about 20–30 minutes if chilled). Remove foil for the last 5–10 minutes to refresh the top. Always reheat to an internal temperature of 165°F for safety.
- Do not leave the casserole out at room temperature for more than 2 hours.
Pro chef tips
- Cook pasta a touch underdone: it will finish cooking in the oven and stay firmer after baking.
- Warm the cream cheese slightly for easier mixing and a smoother sauce.
- Use a rotisserie chicken to save time and add flavor; shredding warm chicken is easier.
- Spread the pasta evenly in the pan and press lightly to avoid large air pockets so it bakes uniformly.
- If you want a crispier top, broil for 1–2 minutes at the very end—watch it closely so it doesn’t burn.
- For less sodium, use reduced-sodium soup and omit or reduce added salt; ranch mixes can be high in salt.
Creative twists
- Veggie-forward: Omit chicken and bacon; add sautéed mushrooms, spinach, or roasted bell peppers. Fold in a can of drained chickpeas for protein.
- Spicy kick: Stir in 1/4–1/2 teaspoon cayenne or red pepper flakes to the sauce, or use pepper jack instead of cheddar.
- Tex-Mex: Replace ranch with taco seasoning, add corn and black beans, and top with sliced avocados and cilantro after baking.
- Lighter version: Swap half-and-half for sour cream and reduce cream cheese by half; use low-fat dairy options (texture will be slightly thinner).
- Gluten-free: Use your preferred GF spaghetti and ensure the cream-of-chicken soup is gluten-free.
Common questions
Q: Can I make this ahead for a party?
A: Yes. Assemble the casserole and refrigerate (covered) up to 24 hours before baking. Add 5–10 minutes to the covered bake time if reheating from chilled.
Q: Can this be frozen after baking?
A: Yes. Cool completely, then freeze in airtight containers for up to 3 months. Thaw overnight in the fridge and reheat in a 350°F oven until 165°F inside.
Q: What if I don’t have ranch seasoning?
A: Use 1 tablespoon dried parsley, 1 teaspoon onion powder, 1 teaspoon dried dill, and 1/2 teaspoon salt as a simple substitute. Adjust to taste.
Q: Is this safe for kids and elders?
A: Absolutely — but check bacon crispness and cut into smaller portions for toddlers. Reheat to 165°F to ensure safe temperatures for vulnerable eaters.
Q: How can I reduce calories without losing flavor?
A: Use rotisserie chicken for flavor, swap half the cream cheese for low-fat cream cheese, and choose reduced-fat sour cream. Add extra vegetables to stretch the dish with fewer calories per serving.
