What Is Pioneer Woman Chicken Spaghetti?
This is a baked pasta casserole inspired by comfort-food classics and popularized by home cooks for its simplicity and crowd-friendly flavor. Spaghetti is cooked al dente, tossed with shredded chicken and a creamy sauce made from chicken broth and cream of mushroom soup, then baked under a blanket of cheddar and mozzarella until bubbly and golden. It tastes savory and creamy with a mild, tangy note from the diced tomatoes with green chilies and a gentle aromatics base of onion and bell pepper. The cooking method is stovetop-to-oven: a quick sauté, a simple mix, then a short bake to marry flavors and melt the cheese. Serve it for weeknight family dinners, casual gatherings, or anytime you need a hearty, make-ahead main that feeds a crowd.
Ingredients for Pioneer Woman Chicken Spaghetti
For the Base
- 8 oz. spaghetti
- 2 cups cooked chicken, shredded
- 2 cups chicken broth
For the Sauce & Mix
- 1 can (10.5 oz.) cream of mushroom soup
- 1 cup diced tomatoes with green chilies
- 1/4 teaspoon garlic powder
- Salt and pepper, to taste
For the Vegetables
- 1/2 cup chopped onion
- 1/2 cup bell pepper, chopped
- 2 tablespoons olive oil
For the Topping
- 1/2 cup grated cheddar cheese
- 1/2 cup grated mozzarella cheese
Ingredient Notes (Substitutions, Healthy Swaps)
- Gluten-free: Swap the spaghetti for a gluten-free spaghetti (rice, corn, or lentil-based). Keep the rest of the recipe the same. Cook pasta according to package instructions.
- Lower sodium: Use low-sodium chicken broth and rinse the canned soup in a bowl before measuring (or choose a reduced-sodium cream soup) to reduce overall salt.
- Dairy alternatives (optional): If you need a dairy-free option, substitute dairy-free cheddar and mozzarella alternatives for the topping; note texture and melt may differ.
- Lighter swap (optional): Reduce the cheeses to 1/4 cup each for a lighter finish, or use part-skim mozzarella and a lower-fat cheddar substitute.
- Chicken options: Any cooked chicken works—rotisserie, leftover roasted chicken, or poached breasts shredded with a fork.
- Vegetable flexibility: The recipe calls for onion and bell pepper, but feel free to use red or green bell pepper based on what you have.
- For a more mushroom-forward flavor (optional), serve alongside a simple mushroom skillet like the 20-minute skillet mushroom chicken to play up the mushroom notes.
Step-by-Step Instructions
Step 1 – Preheat the Oven
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish so the casserole won’t stick.
Visual cue: The oven should be fully heated before the casserole goes in so the cheese melts evenly.
Step 2 – Cook the Spaghetti
Bring a large pot of salted water to a boil. Add the spaghetti and cook according to package instructions until al dente. Drain and set aside.
Visual cue: Pasta should be tender but still have a slight bite (al dente), not mushy.
Pro cue: Save a splash (about 1/4 cup) of the pasta cooking water if you prefer a looser mixture; add it when you combine ingredients.
Step 3 – Sauté the Vegetables
Heat 2 tablespoons of olive oil in a skillet over medium heat. Add the chopped onion and bell pepper and sauté until soft and translucent, about 5 minutes.
Visual cue: Onions will be limp and translucent; peppers will be tender with softened edges.
Pro cue: Don’t brown the vegetables—softening preserves their slightly sweet flavor and blends into the creamy sauce.
Step 4 – Mix the Casserole
In a large mixing bowl, combine the cooked spaghetti, shredded chicken, chicken broth, cream of mushroom soup, diced tomatoes with green chilies, sautéed onion and bell pepper, 1/4 teaspoon garlic powder, salt, and pepper. Mix well so everything is evenly distributed.
Visual cue: The sauce should coat the spaghetti and chicken; you’ll see flecks of tomatoes and green chilies spread through the noodles.
Pro cue: Taste and adjust salt and pepper before transferring to the baking dish—once baked, it’s harder to rebalance seasoning.
Step 5 – Assemble and Top
Transfer the spaghetti mixture into the greased 9×13-inch baking dish and spread evenly. Sprinkle the grated cheddar and mozzarella cheese on top in an even layer.
Visual cue: The top should be fully covered in cheese with no large bare spots.
Pro cue: For a prettier finish, grate your own cheese instead of using pre-shredded, which often contains anti-caking agents that can prevent fully smooth melting.
Step 6 – Bake and Rest
Bake for 25 minutes, or until the cheese is bubbly and golden brown. Remove from the oven and let cool for a few minutes before serving.
Visual cue: Cheese should be melted and slightly golden; edges may bubble up with sauce.
Pro cue: Letting it rest for 5–10 minutes helps the casserole set so portions hold together when served.
Pro Tips for Success
- Heat control: Keep skillet heat at medium when sautéing vegetables so they soften without charring.
- Texture control: Don’t overcook the spaghetti; al dente pasta prevents a mushy casserole after baking.
- Season gradually: Add salt and pepper in stages and taste the mix before baking to avoid over-salting.
- Cheese melting: Use a mix of cheddar and mozzarella for flavor and a stretchy, melty top—both are in the original recipe.
- Even topping: Spread the cheese evenly to ensure consistent browning.
- Timing: If your chicken is cold from the fridge, let it sit at room temperature briefly or warm it slightly; cold chicken can cool the mixture and lengthen baking time.
- Make it ahead: Assemble the casserole, cover tightly, and refrigerate up to 24 hours before baking; add a few extra minutes to the bake time if chilled.
Flavor Variations (OPTIONAL)
- Spicy kick (OPTIONAL): Increase the heat by stirring in a small pinch of cayenne or a few dashes of hot sauce into the mixture before baking.
- Extra cheesy (OPTIONAL): Stir 1/4 cup of shredded cheddar into the spaghetti mixture in addition to sprinkling on top for richer, cheesier bites.
- Veg-forward (OPTIONAL): Add 1/2 cup cooked mushrooms or chopped spinach to the sautéed vegetables—toss in during the last minute of sautéing so they wilt.
- Lighter version (OPTIONAL): Replace half the cheddar and mozzarella with a reduced-fat cheese and use low-sodium chicken broth.
- Crunchy topping (OPTIONAL): For texture, sprinkle 1/2 cup breadcrumbs mixed with a tablespoon of melted butter over the cheese before baking—this is optional and will change the original topping texture.
- Herb boost (OPTIONAL): Finish with a sprinkle of chopped fresh parsley or chives after baking for brightness.
Serving Suggestions
- Simple salad: A crisp green salad with a lemon vinaigrette cuts the richness of the casserole.
- Starchy side: Serve with buttery dinner rolls or warm garlic bread to mop up sauce.
- Veggie side: Steamed green beans or roasted broccoli add color and balance.
- Casual buffet: Present the casserole in the baking dish on a buffet alongside a bowl of pickled vegetables for contrast.
- Weeknight plating: Spoon into shallow bowls and top with a little extra grated cheese or herbs.
- Occasion ideas: Bring to potlucks or family gatherings—this dish feeds a crowd and travels well when kept warm.
Make-Ahead, Storage & Reheating
- Make-ahead: You can fully assemble the casserole, cover tightly with plastic wrap and foil, and refrigerate for up to 24 hours. Add 10–15 extra minutes to the bake time if baking straight from the fridge.
- Refrigerator storage: Store cooled leftovers in an airtight container for up to 3–4 days.
- Reheating (oven): Reheat individual portions in a 350°F oven for 10–15 minutes until warmed through; cover with foil if the top is browning too much.
- Reheating (microwave): Microwave single servings on medium power in 30–60 second intervals, stirring or rotating to promote even heating. The sauce may firm up—add a tablespoon of chicken broth or water if it seems dry.
Storage and Freezing Instructions
- Freezing: This casserole freezes reasonably well. To freeze, assemble the casserole in a freezer-safe dish but do not bake. Wrap the dish tightly with plastic wrap and foil and freeze for up to 2–3 months.
- To bake from frozen: Thaw overnight in the refrigerator, then bake as directed, adding 10–20 minutes if still cold in the center. If baking from frozen (not recommended), tent with foil and bake at 350°F until heated through, which can take significantly longer and may affect texture.
- If you prefer not to freeze the assembled casserole, freeze individual portions in airtight containers for quick lunches—thaw overnight before reheating.
- Note: The texture of the vegetables and cheese may change slightly after freezing; cream-based casseroles can separate a little, but stirring and reheating gently restores a cohesive texture.

FAQ About Pioneer Woman Chicken Spaghetti
Q: My casserole was watery after baking—what went wrong?
A: Likely the pasta was overcooked or too much liquid was used. Use al dente pasta and avoid adding extra broth beyond the 2 cups called for. Let it rest after baking so excess moisture is reabsorbed.
Q: Can I use raw chicken instead of cooked chicken?
A: The recipe calls for cooked chicken. If you use raw chicken, cook and shred it first—baking time in the casserole won’t be enough to safely cook raw poultry through.
Q: How can I prevent the top from getting too brown?
A: If the cheese is browning too quickly, tent the dish loosely with foil halfway through baking.
Q: Can I make this in a smaller dish?
A: Yes, a smaller dish will just be deeper; keep an eye on baking time—it may need a few extra minutes as the interior heats through.
Q: How do I reheat without drying out the casserole?
A: Reheat with a splash of chicken broth or cover with foil in the oven to preserve moisture. In the microwave, heat in short intervals and stir.
Q: Is there a way to make this lower in sodium?
A: Use low-sodium chicken broth and a reduced-sodium or no-salt-added cream of mushroom soup, and go light on added salt.
Notes
- Plating idea: Serve in warm bowls and top with a tiny sprinkle of fresh herbs for color and brightness.
- Small flavor upgrade: A squeeze of fresh lemon or a quick sprinkle of lemon zest right before serving can brighten the dish.
- Seasoning tip: Adjust garlic powder to taste—start with 1/4 teaspoon as written, and only add more after tasting the mixed casserole.
- Presentation tip: Let the casserole rest 5–10 minutes after baking so portions slice neatly for the table.
- Leftover idea: Reheat leftovers and serve over a bed of fresh greens for a quick weeknight salad-meets-pasta bowl.
