Ingredients
Complete List of Ingredients
– 2 cups cooked spaghetti
– 2 cups shredded rotisserie chicken
– 1 can (10.5 oz) cream of chicken soup
– 1 cup chicken broth

This dish starts with cooked spaghetti, which gives it a solid base. The rotisserie chicken makes it easy and adds great flavor. Cream of chicken soup brings creaminess, while chicken broth keeps it moist.
The diced tomatoes with green chilies add a nice kick. Onions and bell peppers provide sweetness and crunch. Garlic gives it a rich taste. I love using onion powder, garlic powder, and paprika to elevate the flavor.
A bit of olive oil helps to sauté the veggies. Finally, fresh parsley is a lovely touch for color and freshness. Each ingredient plays a vital role in making this casserole a warm and comforting dish.

Step-by-Step Instructions
Prepping the Oven and Ingredients
1. Start by preheating your oven to 350°F (175°C). This makes sure your casserole cooks evenly.
2. In a large skillet, heat 1 tablespoon of olive oil over medium heat.
3. Add 1 small finely chopped onion, 1 bell pepper (your choice of color), and 2 cloves of minced garlic.
4. Sauté the mixture for about 5 to 7 minutes. You want them to be soft and fragrant.
Mixing the Casserole
1. Grab a big mixing bowl. Combine 2 cups of cooked spaghetti and 2 cups of shredded rotisserie chicken.
2. Add 1 can of cream of chicken soup and 1 cup of low-sodium chicken broth.
3. Toss in 1 cup of canned diced tomatoes with green chilies and the sautéed veggies.
4. Sprinkle in 1 teaspoon each of onion powder, garlic powder, and smoked paprika. Season with salt and pepper to taste.
5. Mix all the ingredients thoroughly. Make sure everything is evenly coated with the sauce.
Baking the Casserole
1. Lightly grease a 9×13 inch casserole dish to prevent sticking.
2. Pour the mixture into the dish, spreading it out flat.
3. Sprinkle 1 cup of shredded sharp cheddar cheese over the top. Make sure it’s covered well.
4. Place the dish in the preheated oven and bake for 30 to 35 minutes. Check for bubbling and a golden cheese top.
5. When done, take it out and let it cool for about 5 minutes. Garnish with fresh parsley before serving.
Tips & Tricks
Recommended Cooking Techniques
How to cook spaghetti al dente
Cooking spaghetti al dente means it’s firm to the bite. Start with a large pot of boiling water. Add a pinch of salt to enhance the pasta’s flavor. Cook the spaghetti for about 8-10 minutes, checking it a minute or two before the package time. Taste a strand to see if it’s ready. It should not be mushy but have a slight bite. Drain it quickly and rinse it under cold water to stop the cooking process. This step is key to a perfect casserole.
Importance of sautéing vegetables properly
Sautéing vegetables unlocks their flavors. Heat a skillet over medium heat and add olive oil. Once hot, toss in onions, bell peppers, and garlic. Stir them for about 5-7 minutes until they look soft and smell great. This step adds depth to your casserole. If they brown a bit, that’s even better! It gives the dish a rich, savory taste.
Customizing Flavor
Suggestions for additional seasonings
You can adjust the flavor to your taste. Try adding a pinch of cayenne pepper for heat. A dash of Italian seasoning can also brighten the dish. If you love herbs, fresh thyme or oregano works well too. Seasoning is a personal touch, so feel free to experiment until you find your perfect blend.
Using different types of cheese
Cheese makes everything better! While sharp cheddar is classic, try gouda for a smokier taste or mozzarella for extra stretch. You can mix cheeses too for a unique flavor. Just remember, the more cheese, the creamier the casserole.
Serving Suggestions
Best sides to pair with the casserole
This casserole pairs wonderfully with sides. A crisp green salad adds freshness. Warm garlic bread is perfect for soaking up the sauce. You could also serve it with steamed vegetables for color and crunch. These sides balance the richness of the casserole.
How to present the dish beautifully
Presentation matters! Serve the casserole straight from the dish. Top it with freshly chopped parsley for a pop of green. You can also add a sprinkle of cheese on top for visual appeal. Use a colorful plate to make the dish stand out at your table. A beautiful presentation makes every meal feel special.
Pro Tips
- Use Quality Chicken: Opt for a high-quality rotisserie chicken for the best flavor and tenderness. It saves time and adds a rich taste to the casserole.
- Customize Your Veggies: Feel free to add or substitute other vegetables like zucchini or mushrooms to suit your taste or what’s in season.
- Make Ahead: This casserole can be prepared in advance. Assemble it, cover, and refrigerate for up to 24 hours before baking; just add a few extra minutes to the cooking time.
- Leftovers Storage: Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven for best results.
Variations
Healthier Alternatives
You can make this dish lighter by using whole wheat spaghetti. Whole wheat adds fiber and nutrients. It also keeps you feeling full longer.
For the cream of chicken soup, try low-fat alternatives. Look for brands with less fat and sodium. You can even make your own from scratch for better health.
Vegetarian Version
If you’d like a meat-free option, replace the chicken with plant-based proteins. Try using tofu or chickpeas for a great texture.
Make sure to use a vegetarian-friendly broth instead of chicken broth. This keeps the flavor rich while staying meat-free.
Spicy Twist
If you love heat, add jalapeños or a splash of hot sauce. This gives your casserole a fun kick.
You can also experiment with different types of peppers. Bell peppers add sweetness, while serrano or habanero bring more spice. Adjust the heat to suit your taste!
Storage Info
Refrigerating Leftovers
To store your casserole in the fridge, let it cool first. Cover it tightly with foil or plastic wrap. This keeps it fresh and saves moisture. You can also transfer it to an airtight container. The expected shelf life is about 3 to 5 days. After that, the flavors may fade and the texture may change.
Freezing for Future Meals
If you want to freeze your casserole, allow it to cool completely. Then, cut it into portions for easy serving. Wrap each portion in plastic wrap and then in foil. This double layer prevents freezer burn. It’s best to eat frozen casserole within 2 to 3 months for the best taste.
For reheating, move the casserole from the freezer to the fridge a day before. This helps it thaw slowly and keeps it tasty. You can also bake it straight from the freezer, but it will need more time in the oven.
Reheating Recommendations
When reheating, use the oven for the best results. Preheat your oven to 350°F (175°C). Place the casserole in an oven-safe dish and cover it with foil. Bake for about 20 to 30 minutes until it’s hot.
If you’re in a hurry, you can use the microwave. Place a portion in a microwave-safe dish and cover it. Heat in short bursts, stirring in between. This helps it heat evenly. To keep your casserole moist, add a splash of chicken broth before reheating. This will keep it from drying out.
FAQs
Can I use uncooked chicken in this recipe?
Yes, you can use uncooked chicken. Just ensure it cooks fully. To do this, cut the chicken into small pieces. Sauté them in the skillet before adding the other ingredients. This way, the chicken will be tender and flavorful. Cooking the chicken first helps blend its taste with the other ingredients. It also ensures food safety, as raw chicken needs to reach 165°F (75°C).
How do I make this casserole ahead of time?
To prepare this casserole ahead of time, follow these steps:
– Cook the spaghetti and sauté the veggies.
– Mix all ingredients, except for the cheese, in a bowl.
– Place the mixture in a greased casserole dish.
– Cover it tightly with plastic wrap or foil.
– Store it in the fridge for up to 24 hours.
When ready, preheat your oven to 350°F (175°C) and add the cheese on top. Bake for 30-35 minutes until bubbly and golden brown. This method saves time and makes for an easy dinner.
What can I substitute for cream of chicken soup?
You can substitute cream of chicken soup with several alternatives. Here are a few options:
– Cream of mushroom soup: This adds a nice earthy flavor.
– Homemade white sauce: Mix butter, flour, milk, and chicken broth for a creamy base.
– Greek yogurt: This gives a tangy taste and adds protein.
These options change the flavor slightly but still work well in the casserole. Choose what best suits your taste and pantry.
