Betty Crocker’s classic chicken tetrazzini delivers that comforting, creamy pasta magic in one pan—where tender chicken, celery-infused sauce, and al dente noodles come together for a dish that’s equal parts nostalgic and foolproof.
I first fell in love with this recipe during a particularly chilly Georgia winter, when it transformed a simple weeknight into a cozy family meal. The secret lies in balancing the rich creaminess with just enough celery for brightness, ensuring every bite is both indulgent and satisfying.
This recipe follows Betty Crocker’s signature approach: minimal prep, maximum flavor. You’ll start by sautéing chicken and celery until golden, then building a velvety sauce with cream, mushrooms, and a touch of mustard for depth.
The pasta cooks directly in the pan, absorbing all that rich, herby goodness while staying tender—not mushy. It’s the kind of dish that tastes even better the next day, making it perfect for meal prep or feeding a crowd without stress.
What you end up with is a creamy, comforting masterpiece—golden-brown on top, with layers of tender chicken and celery peeking through the luscious sauce.
The aroma alone will have everyone gathering at the table, and the first bite delivers that perfect harmony of textures: al dente pasta, juicy chicken, and a sauce so rich it feels like a hug in a bowl. This is comfort food at its finest, and it’s impossible to resist.
Serve it with a simple side salad or crusty bread to soak up every last drop of that creamy sauce. The leftovers reheat beautifully, making this the ultimate one-pan solution for busy nights. Let’s get cooking—this dish is worth every minute of prep.
Ingredients for chicken tetrazzini betty crocker
Betty Crocker’s nostalgic chicken tetrazzini brings together creamy pasta, tender chicken, and celery magic in one pan.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless Chicken Breast 🍗 | 1 ½ lb | Cut into bite-sized pieces |
| Celery Stalks 🥬 | 3 whole | Sliced thin for flavor |
| Medium Mushrooms 🍄 | 8 oz | Sliced for texture |
| Uncooked Fettuccine 🍝 | 8 oz | Break in half for quicker cooking |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Chicken Broth 💧 | 1 cup | Low-sodium preferred |
| Dijon Mustard 🍯 | 1 tbsp | For depth of flavor |
| Butter 🧈 | 3 tbsp | Unsalted, for sautéing |
| All-Purpose Flour 🌾 | 1 tbsp | For thickening sauce |
| Dried Thyme 🌿 | ½ tsp | Or 1 tsp fresh thyme |
| Garlic Cloves 🧄 | 2 cloves | Minced for aromatic base |
| Salt 🧂 | 1 tsp | Adjust to taste |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Parmesan Cheese 🧀 | ¼ cup | Freshly grated for garnish |
The chicken is the star—go for boneless, skinless breasts (they stay juicier than thighs). Cut them into even-sized pieces so they cook through together. Costco or Walmart usually have pre-sliced celery, but grab a fresh bunch if you can—it makes a huge difference in flavor. For mushrooms, cremini or baby bella work best, but white button mushrooms in a pinch. I always double-check the fettuccine package—some brands cook faster than others, so break them in half if the instructions say 'al dente' in 7-9 minutes. The celery should be crisp, not rubbery, and the mushrooms should be firm without any sliminess.
No heavy cream? Half-and-half with a splash of milk works, though the sauce won’t be quite as rich. Short on chicken broth? Substitute vegetable broth—just add a pinch of chicken bouillon powder to mimic the depth. Dijon mustard out of stock? Yellow mustard in a pinch, but reduce to 1 teaspoon since it’s milder. For the thyme, I grab the Trader Joe’s dried herb blend when I’m lazy, but fresh thyme is worth it if you’ve got it. The garlic? One clove too much can overpower, so start with two and adjust. And if you’re feeling fancy, add a splash of white wine to deglaze the pan after sautéing—the flavor is next-level.
This dish tastes even better the next day, so make extra if you can. Store leftovers in an airtight container for up to 4 days in the fridge, or freeze portions for 3 months. The sauce thickens as it cools, so add a splash of milk or broth when reheating. For serving, I always sprinkle that freshly grated Parmesan on top—it makes the whole dish look and taste gourmet. And save those celery leaves! Toss them into the sauce at the end for a pop of freshness that balances all the creaminess.

Step-by-step instructions for chicken tetrazzini
Here's how to create this rich, creamy celery pasta masterpiece in one pan.
Cook the Chicken and Sauté Vegetables
In a large oven-safe skillet, melt 3 tablespoons butter over medium-high heat. Add the 1.5 lb boneless chicken breast cut into bite-sized pieces and cook for 5-6 minutes until the chicken is lightly browned on all sides and cooked through to 165°F internally. Remove the chicken and set aside.
In the same skillet, add the 3 whole celery stalks sliced thin and the 8 oz medium mushrooms sliced. Cook for 4-5 minutes until the celery softens and the mushrooms release their moisture, then add the 2 cloves garlic cloves minced. Stir for 30 seconds until fragrant. Here's the thing—don't overcrowd the pan or the vegetables will steam instead of brown.
Cook the Pasta and Make the Sauce
Return the cooked chicken to the skillet and add the 8 oz uncooked fettuccine broken in half. Pour in the 1 cup chicken broth and bring to a gentle boil. Reduce heat to medium-low and let the pasta cook in the broth for 8-10 minutes, stirring occasionally, until al dente. You want the pasta to absorb the broth but still have a slight bite.
Meanwhile, in a small bowl, whisk together 1 tablespoon all-purpose flour and 1 tablespoon Dijon mustard. Slowly whisk in 1 cup heavy cream until smooth. Once the pasta is nearly cooked, pour this cream mixture over the pasta and chicken, stirring well to combine. Sprinkle with 0.5 teaspoon dried thyme, 1 teaspoon salt, and 0.5 teaspoon black pepper. The sauce should begin to thicken as it simmers.
Finish and Bake to Perfection
Let the mixture simmer uncovered for 3-4 minutes until the sauce thickens and coats the pasta and chicken. Taste and adjust seasoning if needed. Here's where it gets fun—sprinkle the 0.25 cup parmesan cheese evenly over the top. The cheese will melt into a golden, creamy blanket as it bakes.
Transfer the skillet to a 375°F preheated oven and bake uncovered for 10-12 minutes until the top is golden brown and bubbly. You'll know it's ready when the edges are crispy and the cheese has melted into a silky sauce. Let it rest for 2-3 minutes before serving—this ensures everything stays together when you plate it.
Pro Tips For Making Chicken Tetrazzini Betty Crocker
- POACH CHICKEN FIRST: Skip the pan-fry for the chicken—poach it in simmering broth (chicken or veggie) until it hits 165°F, then shred it. The meat stays juicy, and the sauce absorbs better without drying out. I used to sear it first, but the sauce turned watery every time.
- SALT THE PASTA WATER: Yes, even for tetrazzini. Salt the pasta water before boiling—this seasoning carries through the dish. I learned this the hard way when my first batch tasted bland despite all the cheese and cream.
- SAUTÉ MUSHROOMS UNTIL DRY: Cook the mushrooms until they release all their moisture and turn golden, then wipe the pan with a paper towel. This prevents a soggy sauce later. I skipped this once and ended up with a watery, mushy mess.
- STIR THE SAUCE OFTEN: The heavy cream can split if you ignore it. Stir the sauce every 2–3 minutes while simmering, especially after adding the cheese. It’s tedious, but it guarantees a smooth, creamy finish—not that weird curdled disaster.
Essential equipment for great chicken tetrazzini betty crocker
Oven-Safe Skillet
The foundation of this recipe is a large oven-safe skillet—I swear by my All-Clad Stainless Steel 12-inch skillet for its even heat distribution and durability. This pan handles both stovetop sautéing and oven baking without warping or cracking.
If you don’t have one, a Lodge cast iron skillet works beautifully (just preheat it properly to avoid temperature shocks). Avoid non-stick pans—they can’t handle the high heat needed for browning the chicken and mushrooms properly. 🔥
High-Quality Butter
Never skimp on butter for this dish—unsalted European-style butter like Plugrá or Land O’Lakes Cultured makes all the difference. The higher fat content (82-86%) creates a richer sauce and better browning on the chicken.
I keep a block of Plugrá in my fridge year-round because it’s my go-to for creamy sauces. If you’re watching calories, use half butter and half olive oil, but the texture won’t be quite as luxurious.
Precision Thermometer
A meat thermometer is non-negotiable for perfect chicken—ThermoWorks Thermapen One is my favorite because it’s fast and accurate. The chicken needs to reach 165°F internally before removing it from the pan.
Without one, you risk dry chicken or undercooked meat. Pro tip: I also use it to check the oven temperature—375°F is critical for that perfect golden-brown crust on top. 🌡️
Whisk for Smooth Sauce
For that velvety sauce, a balloon whisk is essential to properly emulsify the cream and flour mixture. I use my OXO Good Grips whisk—it’s sturdy and gets into every corner of my skillet.
If you don’t have one, a fork works in a pinch, but you’ll need to whisk more vigorously. The key is to whisk constantly while adding the cream to prevent lumps. A smooth sauce is what makes this dish feel restaurant-quality.
Cheese Grater
Freshly grated Parmesan transforms this dish—Microplane graters are my secret weapon. They create fine, even shreds that melt beautifully into the sauce. Avoid pre-shredded cheese (it contains anti-caking agents that make the sauce grainy).
For extra flavor, I sometimes add a pinch of Parmesan powder to the sauce before baking—it intensifies the umami notes. 🧀
Measuring Tools
Precision matters in this recipe, especially with the 1 tablespoon flour and 1 tablespoon Dijon mustard—they’re the secret to balancing richness and tang. Use a stainless steel measuring spoon (not plastic) for accuracy. For the thyme, a fine-mesh strainer helps sift out any stems if using fresh.
I keep my OXO stainless steel measuring cups on hand for liquids like the 1 cup heavy cream—they’re dishwasher-safe and never warp. ⚖️

Frequently asked questions
Can I make this chicken tetrazzini with chicken thighs instead of breasts?
Chicken thighs add incredible richness and stay juicier than breasts. Use 1.5 lbs bone-in, skin-on thighs and cook them skin-side down first until golden (8-10 minutes). Remove the skin before adding them back to the pan. The cooking time will be slightly longer, so check for 165°F internal temp. The skin adds extra flavor to the sauce, but it's optional.
Why did my pasta turn mushy when baking?
Overcooking is the most common culprit. Start with al dente pasta and bake for only 10-12 minutes at 375°F. The residual heat in the oven will finish cooking it slightly. If your pasta cooks faster, reduce the baking time by 2 minutes. Also, avoid covering the pan while baking—steam makes pasta soggy.
Can I prepare this dish ahead of time?
This is one of the best make-ahead meals! Assemble everything up to the baking step, cover tightly, and refrigerate for up to 24 hours. When ready to bake, add 5-7 minutes to the baking time (cover with foil first). For freezing, bake completely, cool, then store in an airtight container for 3 months. Reheat covered at 350°F for 20-25 minutes, adding a splash of milk or broth if the sauce seems too thick.
What can I do if my sauce is too thin?
Simmer uncovered for 2-3 extra minutes to let the liquid reduce naturally. If it's still too thin, mix 1 teaspoon cornstarch with 1 tablespoon cold water, stir into the sauce, and simmer for 1 minute until thickened. For a quick fix, sprinkle 1 tablespoon grated Parmesan over the top before baking—the cheese will melt and thicken the sauce as it bakes.
Is there a way to make this dish lower in calories?
Swap the heavy cream for light cream or half-and-half and reduce the butter to 2 tablespoons. Use whole wheat fettuccine (8 oz) and trim excess fat from the chicken. Add 1 cup steamed broccoli to the pan during the final 5 minutes of baking. This keeps the dish satisfying while cutting about 150-200 calories per serving. The flavor will still be rich but lighter.
