Description
A comforting and creamy chicken tetrazzini casserole that’s perfect for freezing and enjoying later. Tender chicken, mushrooms, and spaghetti are combined in a rich Parmesan sauce, then baked to golden perfection.
Ingredients
12 ounces spaghetti
3 tablespoons unsalted butter
8 ounces cremini mushrooms, sliced
1 medium onion, finely chopped
3 cloves garlic, minced
1/4 cup all-purpose flour
3 cups low-sodium chicken broth
1 cup whole milk
1 cup grated Parmesan cheese, divided
2 cups cooked chicken breast, shredded
1/2 teaspoon salt
1/4 teaspoon black pepper
1/4 teaspoon dried thyme
1/4 teaspoon dried parsley
1/2 cup plain Greek yogurt
1/2 cup shredded mozzarella cheese
Cooking spray
Instructions
Preheat the oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with cooking spray.
Cook the spaghetti according to package instructions until al dente. Drain and set aside.
In a large skillet, melt the butter over medium heat. Add the sliced mushrooms and cook until they release their moisture and begin to brown, about 5 minutes.
Add the chopped onion and cook until softened, about 3 minutes. Stir in the minced garlic and cook for 1 minute until fragrant.
Sprinkle the flour over the mushroom mixture and stir constantly for 2 minutes to form a roux.
Gradually whisk in the chicken broth and milk, stirring continuously to avoid lumps. Cook until the sauce thickens, about 5 minutes.
Remove the skillet from heat and stir in 3/4 cup of the Parmesan cheese until melted and smooth.
Add the shredded chicken, salt, black pepper, thyme, and parsley to the sauce. Stir in the Greek yogurt until combined.
In a large mixing bowl, combine the cooked spaghetti and the chicken sauce mixture. Mix well to coat the pasta evenly.
Transfer the mixture to the prepared baking dish. Sprinkle the remaining 1/4 cup Parmesan cheese and shredded mozzarella evenly over the top.
Cover the dish tightly with aluminum foil and bake for 25 minutes.
Remove the foil and bake for an additional 15 minutes, or until the top is golden and bubbly.
Allow the casserole to cool completely before freezing. To freeze, wrap the dish tightly with plastic wrap and then aluminum foil. Label and freeze for up to 3 months.
To reheat from frozen, thaw overnight in the refrigerator. Bake uncovered at 350°F (175°C) for 30-35 minutes until heated through.

Nailing Your Freezer Chicken Tetrazzini: Tips, Tricks, and Fixes
The Magic Behind the Mushrooms and Roux Combo
It’s not just about tossing ingredients together and calling it a day—this dish demands a little finesse. Mushrooms are the unsung heroes here. When you cook them low and slow in butter, they shed their water and caramelize, packing that umami punch. Skip this step, and you’re left with a soggy, bland mess. The roux? Don’t rush it. Sprinkling flour over the softened veggies and stirring for a couple of minutes is key to banishing that raw flour taste. Then, slowly whisking in broth and milk—no lumps allowed—creates a sauce that clings to every spaghetti strand like a dream. This thick, cheesy sauce is what turns this casserole from basic to boss-level comfort food.
Ingredient Swaps That Won’t Kill the Vibe
Out of creminis? No sweat—button mushrooms or even shiitakes work fine. Each brings its own character, so go wild. Whole milk can be swapped for a 2% version if you want to cut calories, but keep the fat somewhere because it keeps the sauce from turning rubbery. Greek yogurt here is the secret weapon instead of heavy cream—adds tang, creaminess, and a protein boost without the grease bomb. For the cheese fans, Parmesan is essential, but you can boost gooey factor by mixing in gouda or provolone if you’re feeling adventurous. Just don’t skip the mozzarella on top—that golden crust? Non-negotiable.
When It All Goes Sideways: Common Fixes
Ever pulled out a tetrazzini only to find the sauce split or the casserole a soggy swamp? Yup, been there. First—if your sauce is too thin, bust out the cornstarch slurry: a teaspoon of cornstarch mixed with cold water, whisked in and heated till it thickens. Too thick? Stir in a splash more broth or milk. Overcooked noodles are the devil—always undercook spaghetti by a minute or two since it’ll keep softening in the sauce and oven. And if you skipped cooling before freezing? That’s a rookie move. Hot casseroles tossed straight into the freezer lead to icy pockets and freezer burn heartache. Patience here is your best friend. Cool completely, then freeze for that fresh-out-of-the-oven feeling when reheated.
Freezer Chicken Tetrazzini FAQs
Absolutely! Linguine or fettuccine work just as well. Just keep an eye on cooking times since thicker pastas might need a tad longer to get al dente.
Yes, you can freeze it before baking, but I prefer baking it first. Baking locks in flavors and textures better, so the reheated dish isn’t soggy or sad.
Up to three months, sealed tight. Anything beyond that risks freezer burn and a less appetizing mouthfeel. Trust me, freshness matters—especially with creamy sauces.
Sure thing! Greek yogurt gives a nice tang without heaviness, but sour cream adds richness. Either way, keep it at about half a cup to keep the sauce smooth and not too runny.
Yes, thaw it overnight in the fridge. Jumping straight from freezer to oven can leave the center icy or unevenly hot, and nobody wants that cold bite in the middle.
