Creamy Rotel Chicken Spaghetti Casserole

Ingredients

• 1 pound spaghetti, broken into halves
• 3 cups cooked chicken, shredded or diced (rotisserie chicken works great!)
• 1 (10.5 ounce) can condensed cream of chicken soup
• 1 (10.5 ounce) can condensed cream of mushroom soup
• 1 (10 ounce) can Rotel diced tomatoes with green chilies, undrained
• 1 (8 ounce) package cream cheese, softened
• 1/2 cup milk (whole or 2%)
• 1/2 cup sour cream
• 1/2 teaspoon garlic powder
• 1/4 teaspoon onion powder
• 1/4 teaspoon black pepper
• 2 cups shredded cheddar cheese, divided
• 1 cup shredded Monterey Jack cheese, divided
• 2 tablespoons fresh parsley, chopped (for garnish, optional)
• Salt to taste

Instructions

1. Preheat Oven & Prepare Pasta: Preheat your oven to 375°F (190°C). Bring a large pot of salted water to a rolling boil. Add the broken spaghetti and cook according to package directions until al dente. Drain well and set aside. Do not overcook the pasta, as it will continue to cook in the oven.
2. Make the Creamy Sauce: In a large mixing bowl, combine the condensed cream of chicken soup, condensed cream of mushroom soup, undrained Rotel diced tomatoes, softened cream cheese, milk, sour cream, garlic powder, onion powder, and black pepper. Whisk until the mixture is smooth and well combined. If the cream cheese is too firm, you can gently warm the mixture in a saucepan over low heat to help it melt and combine easily.
3. Combine Ingredients: Add the cooked and drained spaghetti and the shredded or diced chicken to the large bowl with the creamy sauce. Stir gently to ensure everything is evenly coated.
4. Add Cheese: Fold in 1 cup of the shredded cheddar cheese and 1/2 cup of the shredded Monterey Jack cheese into the spaghetti mixture. Reserve the remaining cheese for the topping.
5. Assemble Casserole: Pour the entire mixture into a 9×13 inch baking dish, spreading it out evenly.
6. Top with Cheese: Sprinkle the remaining 1 cup of cheddar cheese and 1/2 cup of Monterey Jack cheese over the top of the casserole.
7. Bake: Bake for 30-35 minutes, or until the casserole is bubbling around the edges and the cheese on top is melted and lightly golden. If the top starts to brown too quickly, you can loosely cover it with aluminum foil.
8. Rest and Serve: Once baked, remove the casserole from the oven and let it rest for 5-10 minutes before serving. This allows the sauce to set and prevents it from being too runny. Garnish with fresh chopped parsley, if desired.

Cooking Tips and Variations

For the best creamy Rotel chicken spaghetti casserole, consider these tips and variations:

• Pasta Perfection: Cook your spaghetti slightly less than al dente, as it will absorb more liquid and continue to cook in the oven. This prevents mushy pasta.
• Chicken Shortcuts: To save time, use a pre-cooked rotisserie chicken, leftover roasted chicken, or even canned chicken (drained well). If cooking chicken from scratch, boil or bake chicken breasts until cooked through, then shred or dice.
• Spice Level Adjustment: If you prefer less heat, use a mild Rotel or drain some of the liquid from the can. For more heat, add a pinch of cayenne pepper or a dash of your favorite hot sauce to the sauce mixture.
• Cheese Choices: Feel free to experiment with different cheeses! Colby Jack, Pepper Jack (for an extra kick), or even a touch of smoked gouda can add wonderful depth. Freshly grated cheese melts smoother and tastes better than pre-shredded.
• Add Veggies: Boost the nutritional value and flavor by sautéing diced bell peppers, onions, or mushrooms and adding them to the sauce mixture. Frozen peas or corn can also be stirred in during the last few minutes of baking.
• Make it Gluten-Free: Simply swap out regular spaghetti for your favorite gluten-free pasta. Ensure all other ingredients are certified gluten-free.
• Creamier Sauce: For an even richer sauce, replace some of the milk with heavy cream or add an additional ounce or two of softened cream cheese.
• Breadcrumb Topping: For an added textural crunch, mix 1/2 cup of breadcrumbs with 2 tablespoons of melted butter and sprinkle over the cheese topping before baking.
• Prevent Sticking: Lightly grease your baking dish to ensure easy serving and cleanup.

Storage and Reheating

Proper storage and reheating will keep your Creamy Rotel Chicken Spaghetti Casserole delicious for days:

• Refrigeration: Once cooled completely, transfer any leftovers to an airtight container. It will keep well in the refrigerator for up to 3-4 days.
• Freezing: This casserole freezes beautifully! Allow it to cool completely, then wrap it tightly in plastic wrap and then aluminum foil, or place it in a freezer-safe airtight container. It can be frozen for up to 2-3 months. For best results, freeze individual portions for easy reheating.
• Reheating from Refrigerator: For individual servings, microwave on medium power until heated through, stirring halfway. For a larger portion, cover with foil and reheat in an oven preheated to 300°F (150°C) for 20-30 minutes, or until hot and bubbling. You might add a splash of milk or chicken broth if it seems dry.
• Reheating from Freezer: If reheating from frozen, it’s best to thaw the casserole in the refrigerator overnight first. Then, cover with foil and bake in an oven at 350°F (175°C) for 45-60 minutes, or until heated through. Alternatively, you can reheat from frozen, but it will take longer (around 1.5 hours), ensuring it’s covered for most of the baking time to prevent drying out.

Frequently Asked Questions

Can I make this casserole ahead of time?

Yes, absolutely! You can assemble the entire casserole (up to the point of baking) and cover it tightly with plastic wrap, then refrigerate it for up to 24 hours. When ready to bake, remove it from the fridge while the oven preheats, then bake as directed, adding an extra 10-15 minutes to the baking time since it’s starting cold.

What is Rotel?

Rotel is a brand of canned diced tomatoes that are combined with green chilies. It’s a popular ingredient that adds a mild to medium spicy kick and a tangy, savory flavor to many dishes. You can find it in most grocery stores in the canned tomato aisle.

Can I use a different type of pasta?

While spaghetti is traditional for this dish, you can certainly substitute it with other pasta shapes. Penne, rotini, elbow macaroni, or even egg noodles would work well. Just be sure to cook them al dente according to package directions before mixing into the casserole.

My casserole seems a bit dry after baking. What went wrong?

A dry casserole can happen if the pasta was overcooked initially, or if it baked for too long. If you find your casserole consistently dry, try reducing the baking time slightly, or adding an extra splash of milk or chicken broth to the sauce mixture before baking. Covering the casserole with foil for the first half of baking can also help retain moisture.
