Introduction
Classic Creamy Chicken Tetrazzini is a comforting, versatile dish that many home cooks cherish. With its origins tracing back to the early 20th century, this indulgent casserole embodies a delightful balance of flavors and textures.
Whether you're using leftover roast chicken or starting from scratch, this dish combines tender chicken, hearty pasta, and a velvety sauce. It's an ideal way to bring the family together around the dinner table for a cozy evening.
Ingredients
- 2 cups cooked chicken, shredded
Shredded chicken serves as the star of the dish, offering protein and a comforting texture. Using leftover roasted chicken can also deepen the flavor, making this dish a great way to utilize kitchen scraps. - 8 ounces spaghetti or fettuccine
Pasta acts as the foundation of the tetrazzini, providing a hearty base that soaks up the creamy sauce. Spaghetti is classic, but feel free to substitute with other varieties like egg noodles. - 1 tablespoon olive oil
Olive oil adds richness and helps sauté the onions and garlic, ensuring they develop a nice flavor before being incorporated into the sauce. It's also a healthier fat option, contributing to the dish's overall taste. - 1 medium onion, diced
Onions serve as a flavor base that enhances the overall taste of the casserole. Sautéing them until golden brings out their natural sweetness, balancing the dish's richness. - 2 cloves garlic, minced
Garlic adds an aromatic depth that elevates the entire dish. It complements the chicken and cream without overpowering, making it a staple in many savory recipes. - 8 ounces mushrooms, sliced
Mushrooms provide an earthy flavor and chewy texture, complementing the chicken's tenderness. Their moisture also helps keep the tetrazzini from becoming too dry. - 1/4 cup all-purpose flour
Flour acts as a thickening agent for the creamy sauce. Mixing it with the sautéed vegetables forms a roux, which enhances consistency and prevents a runny final dish. - 2 cups chicken broth
Chicken broth adds a rich, savory liquid base that infuses the tetrazzini with flavor. It's essential for creating the creamy sauce and ties all the ingredients together. - 1 cup heavy cream
Heavy cream creates the signature richness of the sauce, contributing to its luxurious texture. This ingredient is crucial for achieving that creamy mouthfeel associated with classic tetrazzini. - 1 cup grated Parmesan cheese
Parmesan adds a salty, nutty depth that enhances the overall flavor. It's also helpful for creating a lovely golden crust when the dish is baked. - Salt and pepper to taste
Seasoning the dish with salt and pepper is vital for balancing and highlighting the flavors of the other ingredients. Taste as you go to ensure an inviting flavor profile. - 1/2 cup frozen peas
Frozen peas bring a pop of color and a sweet note to the dish. They're an easy addition that boosts the nutritional value without complicating the recipe. - 1/2 teaspoon dried thyme
Thyme introduces an aromatic earthiness that beautifully complements the chicken and cream. It’s subtle, yet its presence enriches the overall flavor of the casserole.
Directions & Preparation
Step 1: Preheat your oven to 350°F (175°C).
Preheating the oven before you start preparing your dish ensures that it reaches the ideal temperature for baking. This step is crucial for properly cooking and browning your tetrazzini, resulting in a delightful crust and thoroughly heated interior.
Step 2: Cook the pasta according to package instructions until al dente. Drain and set aside.
Cooking the pasta until it’s al dente means it will retain a slight bite and prevents it from becoming mushy during the baking process. It’s important to reserve the pasta for later, ensuring it’s ready to absorb the creamy sauce.
Step 3: In a large skillet, heat the olive oil over medium heat. Add the diced onion and sauté until translucent, about 5 minutes.
Sautéing the onions until they’re translucent enhances their natural sweetness and builds a flavorful base for the dish. This step also allows the onions to release their moisture, which is important for the overall texture of the casserole.
Step 4: Add the minced garlic and sliced mushrooms. Continue to sauté for an additional 5-7 minutes, until the mushrooms are softened.
Adding the garlic after the onions prevents it from burning, which would create a bitter flavor. Sautéing the mushrooms until they are softened allows them to release their moisture and integrate into the dish, providing essential flavor.
Step 5: Sprinkle the flour over the vegetable mixture and stir for 1-2 minutes to cook the flour lightly.
Cooking the flour in the skillet creates a roux that will thicken the sauce. This step is crucial to remove any raw flour taste, ensuring the final dish is rich and smooth.
Step 6: Gradually whisk in the chicken broth, ensuring there are no lumps. Allow the mixture to simmer for 5 minutes, stirring frequently until thickened.
Gradually whisking in the broth prevents lumps from forming, leading to a creamy consistency. Simmering thickens the sauce by allowing the flour to absorb moisture, creating a delightful base for the tetrazzini.
Step 7: Stir in the heavy cream, Parmesan cheese, cooked chicken, thawed peas, dried thyme, salt, and pepper.
Incorporating the cream and cheese adds that unmistakable richness associated with creamy sauces. This is the moment to taste and adjust seasoning, ensuring your dish has well-balanced flavors.
Step 8: Combine the cooked pasta with the sauce mixture, ensuring the noodles are well-coated.
Mixing the pasta with the sauce is essential to ensure every noodle is smothered in the creamy goodness. This guarantees consistent flavor and texture throughout the dish.
Step 9: Transfer the mixture into a greased baking dish, smoothing the top with a spatula.
Transferring to a greased baking dish prevents sticking and allows for easy servings later. Smoothing the top can also help create an even browning when baked.
Step 10: Sprinkle additional Parmesan cheese on top for a cheesy crust.
Adding more cheese on top before baking contributes to a crispy, golden crust that provides a delightful texture contrast with the creamy filling. This finishing touch enhances the overall presentation.
Step 11: Bake in the preheated oven for 25-30 minutes, until bubbly and golden brown on top.
Baking allows the flavors to meld and develop fully. Checking for a bubbly texture and golden color on top signals that your dish is ready to come out of the oven, ensuring a comforting and inviting appearance.
Step 12: Let the dish cool for a few minutes before serving. Garnish with fresh herbs if desired.
Letting the dish rest before serving helps the flavors settle and allows for easier portioning. Garnishing with fresh herbs enhances the presentation and adds a touch of brightness.
