Ingredients
• 1 pound spaghetti
• 4 ounces fresh baby spinach, chopped
• 2 cups cooked and shredded chicken
• 1 egg, beaten
• 30 ounces Alfredo sauce
• 15 ounces ricotta cheese
• 1/2 cup sour cream
• 2 cups shredded mozzarella cheese, divided
• 3 cloves garlic, minced
• 1 teaspoon dried basil or oregano
• Salt and pepper, to taste
Instructions
Step 1: Preheat and Prepare the Pasta
1. Preheat your oven to 350°F (175°C) to ensure it reaches the proper temperature by the time you’re ready to bake.
2. Bring a large pot of salted water to a boil. Add the spaghetti and cook until al dente, following the package instructions. Once the pasta is perfectly tender yet firm to the bite, drain it well and set aside. This initial boiling step is crucial because the pasta will continue to cook slightly during baking, so undercooking it a little now helps maintain its ideal texture later.
Step 2: Combine Main Ingredients
1. In a large mixing bowl, combine the drained spaghetti, shredded chicken, chopped spinach, and Alfredo sauce. Stir gently until all ingredients are evenly coated. The Alfredo sauce will not only add a creamy texture but will also serve as the base flavor that ties the dish together.
2. Taste the mixture and season with a pinch of salt and pepper if needed, keeping in mind that the sauces and cheeses already carry some seasoning.
Step 3: Assemble the Layers
1. Lightly grease a 9×13-inch baking dish with cooking spray or a little butter to prevent sticking.
2. Spread half of the spaghetti mixture evenly into the bottom of the baking dish, creating the first flavorful layer. This foundation layer sets the stage for the creamy and cheesy components that follow.
3. In a separate bowl, combine the ricotta cheese, sour cream, half of the shredded mozzarella cheese, the beaten egg, minced garlic, dried basil (or oregano), and an additional pinch of salt and pepper. Mix the ingredients thoroughly until you achieve a smooth, cohesive spreadable mixture.
4. Carefully spread the ricotta mixture over the first layer of spaghetti, ensuring that it covers the entire surface evenly. This layer adds a luscious, creamy texture that balances the savory flavors of the chicken and spinach.
5. Gently layer the remaining spaghetti mixture over the ricotta layer, pressing lightly to ensure even coverage.
6. Finally, sprinkle the remaining shredded mozzarella cheese evenly on top. The mozzarella will melt and bubble beautifully during baking, forming a golden, cheesy crust.
Step 4: Bake and Set
1. Place the assembled dish in your preheated oven and bake for approximately 20 minutes. The baking time allows the cheeses to melt and the flavors to meld together, creating a harmonious blend in every bite.
2. Keep an eye on the dish towards the end of the baking period. The cheese should be bubbly and starting to turn golden brown. If you prefer a crispier top, you can bake for an additional 5 minutes, but be cautious not to overbake as it may dry out the pasta.
3. Once done, remove the dish from the oven and let it cool for a few minutes. This resting period is essential as it helps the layers set, making the dish easier to serve and enjoy without losing its structured layers.
Tips
• Pasta Texture: For the best texture, ensure your spaghetti is cooked just until al dente. This prevents the pasta from becoming mushy during the baking process.
• Chicken Options: Use pre-cooked, shredded chicken for convenience, or cook your chicken with your preferred seasonings beforehand for extra flavor. Rotisserie chicken is an excellent option for a quick meal.
• Spinach Variation: Fresh baby spinach works wonderfully, but if you’re short on time, you can substitute with thawed frozen spinach. Just be sure to squeeze out any excess water before adding it to the mix.
• Cheese Choices: While ricotta and mozzarella are the stars here, you can experiment with adding a sprinkle of Parmesan cheese for an extra layer of flavor.
• Herb Flexibility: The recipe calls for dried basil or oregano, but feel free to experiment with a combination of both or add a touch of Italian seasoning for a more complex flavor profile.
• Layering: When assembling the dish, be gentle with the layers. Overmixing or pressing too hard might cause the layers to blend together, which could affect the final presentation and texture.
• Extra Creaminess: If you desire an even creamier dish, consider adding a bit more sour cream or a splash of heavy cream into the ricotta mixture.
Storage Options
• Room Temperature: The baked spaghetti is best enjoyed fresh, but if you have leftovers, allow them to cool completely before covering. Store in an airtight container at room temperature for up to 2 hours if you plan to eat it within the same day.
• Refrigeration: For longer storage, cover the dish tightly with plastic wrap or transfer it to a container and refrigerate for up to 3-4 days. Reheat individual portions in the microwave or warm the entire dish in the oven at 350°F (175°C) until heated through.
• Freezing: You can freeze this dish for up to 2 months. To freeze, cover the cooled spaghetti tightly with foil or plastic wrap and place it in a freezer-safe container. When ready to serve, thaw overnight in the refrigerator and reheat in the oven. Note that freezing may slightly alter the texture, so the dish might be best enjoyed when freshly baked.
• Reheating Tip: When reheating, especially in the microwave, consider adding a splash of water or extra Alfredo sauce to help restore the moisture and creaminess of the pasta.
In conclusion, Baked Spinach Chicken Spaghetti is a delightful, comforting dish that marries the creamy indulgence of a baked pasta casserole with the wholesome goodness of chicken and spinach.
