Betty Crocker's chicken tetrazzini recipe delivers that nostalgic, creamy comfort we all crave—especially when dinner needs to feel special without hours in the kitchen.
Growing up in Georgia, I remember my grandmother’s version, where crispy chicken and tender pasta disappeared into a rich mushroom sauce faster than we could plate it. This recipe captures that same magic, but with a modern twist that keeps it restaurant-worthy at home.
The secret lies in the celery-crust topping—crispy, herby, and golden—that contrasts perfectly with the velvety mushroom sauce. We’re talking creamy without being heavy, thanks to a blend of cream cheese and sour cream that thickens just right as it bakes.
The chicken stays juicy, the pasta holds its shape, and every bite feels like a warm hug on a chilly evening.
This dish is foolproof for weeknights but impressive enough for company—ready in about 45 minutes with just one skillet and a baking dish. The celery crust adds texture that keeps it interesting, while the mushroom sauce delivers that deep, umami richness that makes tetrazzini unforgettable.
Trust me, once you try this version, you’ll never go back to the boxed stuff.
Serve with a crisp green salad to balance the richness or a sprinkle of parsley for freshness. The leftovers reheat beautifully, making it perfect for meal prep or feeding a crowd. Let’s get cooking—your taste buds will thank you.
Ingredients for chicken tetrazzini betty crocker
Celery crust, creamy mushroom sauce, and tender chicken—just the ingredients you need for nostalgic comfort.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless, Skinless Chicken Breast 🍗 | 2 ½ lb | Cut into bite-sized pieces |
| Fettuccine Pasta 🍝 | 12 oz | Uncooked, medium width |
| Cream Cheese 🧈 | 8 oz | Full-fat, room temperature |
| Sour Cream 🥛 | 1 cup | Full-fat for creaminess |
| Heavy Cream 🥛 | ½ cup | Whole milk preferred |
| Mushrooms 🍄 | 1 ½ lb | Button or cremini, sliced |
| Celery Stalks 🧅 | 2 whole | Finely chopped, fresh |
| Yellow Onion 🧅 | 1 whole | Finely diced |
| Garlic Cloves 🧄 | 4 cloves | Minced, fresh |
| All-Purpose Flour 🌾 | ¼ cup | For celery crust |
| Parmesan Cheese 🧀 | ½ cup | Freshly grated |
| Chicken Broth 💧 | 1 cup | Low-sodium preferred |
| Dried Parsley 🌿 | 1 tbsp | Or 2 tbsp fresh chopped |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
The celery crust is where the magic happens. Fresh celery from the grocery store’s produce section (not the pre-chopped kind) gives the best flavor—just chop it fine. For the mushrooms, cremini or button work great, but avoid the pre-sliced ones—they brown too fast. I always grab Penzeys dried parsley if I’m making a big batch, but the regular grocery store stuff works fine. The chicken breast should be boneless, skinless, and cut into even pieces—that way, it cooks perfectly without drying out. Fettuccine is the classic choice, but pappardelle or tagliatelle would work too if that’s what you’ve got.
No cream cheese? Cottage cheese blended smooth gets you close, though it won’t be as rich. Short on sour cream? Greek yogurt at half the amount works in a pinch, but trust me on the full-fat version. The heavy cream can be swapped for half-and-half, but the sauce won’t be as velvety. For the celery crust, if you don’t have fresh parsley, dried works at one-third the amount. The mushrooms can be swapped for shitake or oyster mushrooms—they add a deeper umami flavor. And if you’re short on time, pre-minced garlic from the jar is fine (just drain it well).
This dish reheats beautifully—honestly tastes better the next day once everything melds together. Keeps in the fridge for 4-5 days covered tightly, and freezes for 3 months if you portion it into containers. I always make a double batch because it’s perfect for meal prep. The celery crust stays crispy if you reheat it covered with foil for 10 minutes, then uncover to crisp up. Serve it with a crisp green salad to balance the richness—arugula or mixed greens** work great.

- Creamy Crisp Contrast: Here’s what sold me—the way the chicken stays tender but gets a just-right golden crust from the oven, while the fettuccine swims in that thick, tangy cream sauce. It’s the kind of dish where every bite has that satisfying two-textures-at-once magic.
- Lunchbox Hero: Between us, this is my go-to for meal prep. The leftovers reheat like a dream (no soggy pasta here) and pack perfectly for work lunches—just add a side salad or some crusty bread. Honestly, my coworkers keep asking for seconds, and I’m not even trying that hard.

Step-by-step instructions for celery-crusted chicken tetrazzini
Here's how to build layers of rich, creamy goodness with that signature celery crust.
Cook the Chicken and Prepare the Celery Crust
In a large skillet, heat 1 tablespoon olive oil over medium-high heat. Add the 2.5 lb boneless, skinless chicken breast cut into bite-sized pieces and cook for 5-6 minutes until the chicken is lightly browned on all sides and reaches an internal temperature of 165°F. Remove the chicken and set aside.
In the same skillet, add the 1 whole yellow onion and 2 whole celery stalks, both finely chopped. Cook for 5 minutes until softened. Stir in the 4 cloves garlic cloves and cook for 30 seconds until fragrant. Remove from heat and transfer to a bowl. Add the 0.25 cup all-purpose flour and 1.5 tsp salt, mixing well to create the celery crust mixture. Set aside.
Sauté the Mushrooms and Cook the Pasta
In a separate large skillet, heat 1 tablespoon olive oil over medium heat. Add the 1.5 lb mushrooms sliced and cook for 8-10 minutes until they release their moisture and turn golden brown. Remove from heat and set aside.
While the mushrooms cook, bring a large pot of salted water to a boil. Add the 12 oz fettuccine pasta and cook for 1 minute less than the package instructions suggest for al dente pasta. Drain and set aside, reserving 1 cup pasta water.
Build the Creamy Sauce Base
In the same skillet used for the mushrooms, reduce heat to medium-low. Add the 8 oz cream cheese and stir until melted and smooth. Pour in the 1 cup sour cream and 0.5 cup heavy cream, stirring constantly until well combined. Add the 1 cup chicken broth and 1 tbsp dried parsley, stirring until the sauce begins to thicken slightly.
Here's the thing—if the sauce looks too thick, add 1-2 tablespoons of reserved pasta water to loosen it to a creamy consistency. Stir in the 0.5 cup freshly grated parmesan cheese and 0.5 tsp black pepper, mixing until fully incorporated. The sauce should be rich and velvety, ready to coat every strand of pasta.
Assemble and Bake the Tetrazzini
Preheat your oven to 375°F. In a large, greased baking dish, combine the cooked fettuccine pasta, sautéed mushrooms, and the celery crust mixture. Gently fold everything together, then spread evenly in the baking dish. Pour the creamy sauce over the top, making sure it's well distributed.
Sprinkle the cooked chicken evenly over the pasta mixture. The chicken should be partially submerged in the sauce to absorb all that rich flavor. Bake uncovered for 20-25 minutes until the top is golden brown and the edges are bubbling. The center should still be slightly jiggly—this ensures it stays creamy.
Broil for the Perfect Crust
Switch your oven to broil and broil the tetrazzini for 2-3 minutes until the top develops a beautiful golden-brown crust. Watch it closely—you want that celery crust to be crispy and inviting, not burnt. Remove from the oven and let it rest for 5-10 minutes before serving.
This resting time allows the layers to set slightly, making it easier to serve without losing all that creamy goodness. The result? A comforting, creamy dish with layers of flavor and that signature celery crust that makes this recipe truly special.
Pro Tips For Making Chicken Tetrazzini Betty Crocker
- Prep Celery Like a Pro: I used to chop celery in big chunks, but this recipe needs it finely diced—think rice-sized pieces. A sharp knife and a steady hand (or a food processor pulse) make all the difference for that signature celery crust texture, not a mouthful of celery sticks.
- Don’t Overcook the Pasta: The recipe says 1 minute less than package instructions for al dente pasta, and that’s non-negotiable. Overcooked fettuccine turns mushy under the sauce, and nobody wants a soggy tetrazzini—especially when you’ve gone this far.
- Melt Cream Cheese Slow: After burning three batches, I finally learned: medium-low heat only for the cream cheese. High heat curdles it faster than you can say “disaster,” and you’ll be scraping gunk off the skillet. Stir constantly—this isn’t the time to walk away.
- Broil with a Watchful Eye: That final 2-3 minutes under the broiler can turn golden perfection into charcoal in seconds. Keep the oven door cracked and peek every 30 seconds—you’re aiming for crispy, not burnt. A spatula under the dish helps too if it’s stubborn.
Make-ahead tips for this chicken tetrazzini betty crocker
Prep Ahead for Efficiency
I always chop all my vegetables the night before—yellow onion, celery, and mushrooms—and store them in airtight containers with a damp paper towel. This saves 20 minutes of prep time on the day you cook.
Just pull them out and let them sit at room temperature for 15 minutes before cooking to remove excess moisture. 🌟
Cook Chicken First
Cut the 2.5 lb chicken breast into even pieces and season with 1 tsp salt and ¼ tsp black pepper. Cook them first while you prep the rest of the ingredients.
This way, they’re ready to go when you’re assembling the dish. I like to keep them warm in a low oven (200°F) until ready to use.
Make the Sauce Base
Prepare the creamy sauce base in advance by melting the 8 oz cream cheese with ½ cup heavy cream and ½ cup sour cream. Store it in a sealed container in the fridge for up to 2 days.
When ready to assemble, just stir in the remaining ½ cup heavy cream, 1 cup chicken broth, and 1 tbsp dried parsley. This keeps the sauce from drying out while you focus on other steps.
Pre-Cook the Pasta
Cook the 12 oz fettuccine one minute less than package instructions and drain. Toss it with 1 tbsp olive oil to prevent sticking. Store it in a container with a lid until ready to assemble.
This way, you can focus on the sauce and chicken without worrying about the pasta getting cold.
Assemble the Night Before
Layer the pasta, mushrooms, and celery crust mixture in your baking dish, then pour the sauce over it. Cover tightly with foil and refrigerate for up to 24 hours.
When ready to bake, sprinkle the cooked chicken on top and follow the original baking instructions. The flavors meld beautifully overnight! 💛
Freezer-Friendly Portions
Divide the fully assembled (but unbaked) tetrazzini into quart-sized freezer bags and freeze for up to 3 months. When ready to eat, thaw in the fridge overnight, then bake as directed. The sauce will stay creamy, and the celery crust will crisp up beautifully in the oven.

Frequently asked questions
Why does the celery crust add so much flavor to chicken tetrazzini?
The celery crust isn’t just for texture—it’s packed with natural sweetness and a subtle earthiness that balances the rich creaminess of the dish. When sautéed with onion and garlic, the celery caramelizes slightly, adding depth that ties all the flavors together. This classic pairing transforms simple ingredients into something truly special.
Can I use a different type of pasta for this recipe?
While fettuccine is traditional, you can swap in pappardelle, tagliatelle, or even penne for a fun variation. Just adjust cooking times to match package instructions—al dente is key. The sauce will adapt beautifully to any pasta shape, though wider noodles will soak up more of that creamy goodness.
What’s the best way to reheat leftovers without drying out the sauce?
Cover tightly with foil and reheat in the oven at 350°F for 20 minutes, then uncover for the last 5 minutes to crisp the crust. Microwaving works too, but add 1-2 tablespoons of water to a plate and nestle the dish on top to prevent drying. The sauce will stay luscious either way!
Is it possible to make this dish dairy-free?
Yes! Replace the cream cheese with cashew cream or coconut cream (thinned with broth), and swap sour cream for coconut yogurt. The texture will be slightly lighter, but the umami from mushrooms and garlic will keep it satisfying. Just test a small batch first to adjust seasoning needs.
Why should I let the tetrazzini rest before serving?
Resting for 5-10 minutes lets the layers set just enough to hold together when you serve. This prevents the creamy sauce from spilling out when you cut into it, and gives the celery crust time to crisp up fully. Patience here makes all the difference for that perfect first bite!
