Ingredients You’ll Need

- 8 ounces sliced cremini mushrooms (or white mushrooms): Choose cremini for a deeper flavor; make sure to sauté them until browned.
- 1 cup diced yellow onion (1 medium onion): It provides a sweet, aromatic base to the sauce.
- ¾ teaspoon kosher salt: Enhances the flavors of all the ingredients.
- ¼ teaspoon coarse ground black pepper: Adds a little kick without overpowering.
- 3 cloves garlic, minced: Essential for its aromatic quality, infusing the dish with richness.
- 3 tablespoons all-purpose flour: Helps thicken the sauce for a creamy texture.
- 2 cups low-sodium chicken broth: Keeps the dish flavorful without adding too much salt.
- 1 ½ cups half and half: This creates the luscious, creamy sauce foundation.
- 8 ounces dry spaghetti, broken in half: The star of the dish—choose whole wheat or gluten-free versions for alternatives.
- 3 cups cooked diced chicken (about 2 large boneless skinless chicken breasts): Essential for protein; leftovers work perfectly here.
- 1 cup frozen peas (unthawed): Adds a pop of color and sweetness.
- 1 cup shredded mozzarella cheese: Melts beautifully for that cheesy topping.
- ½ cup grated parmesan cheese: Brings a salty depth to the dish.
- 2 tablespoons minced fresh parsley: Freshens the flavors and provides color.
- ½ cup panko breadcrumbs: Gives a delightful crunch on top.
- ¼ cup grated parmesan cheese: Another layer of flavor that crisps in the oven.
- 2 tablespoons minced fresh parsley: Enhances presentation and adds freshness.
- 1 tablespoon olive oil: Aids in achieving a golden crust on the topping.

How to Make Chicken Tetrazzini
- Prep the Ingredients: Measure 1 ½ cups half and half and let it warm slightly on the counter. Preheat your oven to 375°F and lightly grease a 9 × 13-inch baking dish to prevent sticking.
- Sauté the Vegetables: Melt 3 tablespoons of unsalted butter in a large skillet over medium to medium-high heat. Add 8 ounces of sliced mushrooms, 1 cup of diced yellow onion, ¾ teaspoon kosher salt, and ¼ teaspoon coarse ground black pepper. Sauté until the mushrooms release their moisture and start to brown, which should take around 6 minutes.
- Create the Sauce: Stir in 3 cloves of minced garlic, letting them cook for about 1 minute. Sprinkle in 3 tablespoons of all-purpose flour, stirring constantly to combine. Slowly stir in 2 cups of low-sodium chicken broth, scraping up any browned bits from the pan. Then gradually add your warmed half and half, stirring constantly to achieve a smooth texture.
- Cook the Pasta: Bring your sauce to a gentle boil and toss in 8 ounces of broken spaghetti by the handful, stirring gently to separate the strands. Reduce the heat to maintain a lively simmer, and cook for 10 to 12 minutes, stirring often until the pasta is just shy of al dente. This means it will finish cooking in the oven, absorbing more flavor.
- Prepare the Topping: While your pasta cooks, prepare the crunchy topping. In a small bowl, mix together ½ cup of panko breadcrumbs, ¼ cup of grated parmesan cheese, 2 tablespoons of minced parsley, and 1 tablespoon of olive oil. Set aside.
- Combine Ingredients: Once the pasta is sufficiently tender, fold in 3 cups of cooked diced chicken, 1 cup of frozen peas, 1 cup of shredded mozzarella cheese, ½ cup of grated parmesan cheese, and 2 tablespoons of minced parsley. Mix everything together until well combined.
- Transfer and Bake: Pour the mixture into your prepared baking dish, spreading it evenly. Sprinkle the breadcrumb mixture on top. Bake uncovered for approximately 25 minutes, or until bubbly and the topping is golden brown.
- Serve: Let your beautiful casserole cool for about 5 minutes before serving it hot. Enjoy the smiles around your table!

Storing & Reheating
To store Chicken Tetrazzini, let it cool completely and transfer it to an airtight container. It can be kept in the refrigerator for up to 3 days. If you want to keep it longer, freeze it for up to 3 months; just ensure it’s in a freezer-safe container. When it’s time to enjoy leftovers, simply reheat in the oven at 350°F for about 20 minutes or until heated through. Keep in mind that while the flavors remain rich, the texture may alter slightly, so a drizzle of extra half and half can rejuvenate the creaminess.
Chef’s Helpful Tips
- Watch your pasta closely while it’s simmering—overcooking can lead to mushy spaghetti.
- Make sure your chicken is cooked and cooled before dicing; warm or hot chicken can cause uneven cooking in the casserole.
- A splash of white wine added to the mushrooms creates an extra depth of flavor.
- If it feels too creamy for your taste, consider adding a bit of lemon juice or zest to brighten it up.
- For a crunchier topping, broil the dish for a minute or two at the end of baking—just watch it closely so it doesn’t burn!
- This casserole is perfect for meal prep; you can assemble it ahead of time and pop it in the oven when you’re ready to eat.
Chicken Tetrazzini is a delightful dish that brings warmth and comfort to the table. It checks all the boxes—easy to prepare, budget-friendly, and full of fantastic flavors.
