Ingredients for chicken tetrazzini betty crocker
Creamy, comforting ingredients that transform simple pantry staples into a restaurant-worthy dish.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless, Skinless Chicken Breast 🍗 | 1 ½ lb | Cut into bite-sized pieces |
| Fettuccine Pasta 🍝 | 12 oz | Al dente preferred |
| White Mushrooms 🍄 | 8 oz | Sliced into thin pieces |
| Yellow Onion 🧅 | 1 whole | Diced small |
| Celery Stalks 🥬 | 2 whole | Cut into thin strips |
| Heavy Cream 🥛 | 1 cup | Full-fat for best texture |
| Chicken Broth 💧 | 1 cup | Low-sodium preferred |
| Grated Parmesan Cheese 🧀 | 1 cup | Freshly grated preferred |
| Butter 🧈 | 4 tbsp | Unsalted, melted |
| All-Purpose Flour 🌾 | 2 tbsp | For sauce thickening |
| Garlic Cloves 🧄 | 3 cloves | Minced finely |
| Dried Thyme 🌿 | 1 tsp | Or 1 tbsp fresh |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
The chicken is your foundation—boneless, skinless breasts cook evenly and stay tender. Costco or Walmart usually have pre-cut chicken at great prices, but grab whole breasts if you want to trim the fat yourself. For the mushrooms, cremini or baby bella add extra depth, but white mushrooms work perfectly fine. The celery? Look for crisp stalks—avoid the rubbery ones. I always buy extra celery for the crown topping, since it adds that satisfying crunch. Fresh thyme makes a difference here, but dried works in a pinch (just use half the amount).
No heavy cream? Half-and-half with a splash of milk gets you close. Short on Parmesan? Pecorino Romano works too, though it's stronger. The pasta needs to be al dente—undercook by 1 minute if you're nervous. For the celery crown, cut the stalks into 3-inch pieces and arrange them in a star pattern before baking. If you're making this ahead, assemble everything except the celery crown—add that last minute so it stays crisp.
This reheats beautifully—just add a splash of milk or broth to loosen the sauce. Keeps in the fridge for 4-5 days, freezes for 3 months. I always make extra because it tastes even better the next day. For the celery crown, bake it separately at 375°F for 8-10 minutes—don't skip this step, it's the showstopper. Store leftovers covered to keep the celery crisp.
Why You'll Love This Recipe
- One-Pot Magic: That golden-brown crust hiding a creamy, dreamy center? It all happens in one skillet—no extra pans, no frantic cleanup. I toss the chicken in, sear it golden, then build the sauce right over the mushrooms, onions, and celery. By the time I add the pasta and bake, the whole thing comes together like a pro move, not a chore.
- Creamy, Umami Bomb: The heavy cream and parmesan make this dish so rich, but here’s the secret: those mushrooms and celery, caramelized just right, add depth that makes it ridiculously good. That garlic and thyme? They’re the flavor glue—simple but impossible to resist.
- Leftover Legend: This isn’t just dinner—it’s a meal for days. I make it on Sunday, and by Wednesday, I’m still sneaking bites of the crispy edges. Freezes like a dream too, so if you double the recipe, you’ve got a weeknight lifesaver. My kids even ask for seconds (yes, even on a Tuesday night).
- Budget-Friendly Luxe: Full-fat cream and parmesan might sound fancy, but the chicken breasts and mushrooms stretch far for a crowd. I serve it with a side salad, and suddenly it feels like a restaurant-worthy meal without the price tag. The flour and broth keep the sauce luscious without waste.
Step-by-step instructions for creamy chicken tetrazzini
Here's how to build that iconic creamy mushroom-pilaf layer with tender chicken and celery crown—simple steps for maximum flavor.
🍳 Step 1: Cook the Pasta Al Dente and Reserve Water
Bring a large pot of salted water to a rolling boil. Add the 12 oz fettuccine pasta and cook for 1 minute less than the package directions—you want it al dente. Stir occasionally to prevent sticking. The pasta should have a slight bite when you taste-test.
Right before draining, scoop out 1 cup of the starchy pasta water. This golden liquid is your secret weapon for creating that signature creamy sauce. Don't rinse the pasta—those surface starches help the sauce cling beautifully. Drain and set aside on a plate.
👨🍳 Step 2: Sear Chicken and Sauté Mushroom-Celery Pilaf
In a large oven-safe skillet, melt 1 tbsp butter over medium-high heat. Add the 1.5 lb boneless, skinless chicken breast cut into bite-sized pieces and cook for 4-5 minutes until golden brown on all sides. Remove chicken and set aside.
In the same skillet, add the remaining 3 tbsp butter. Toss in the 8 oz sliced white mushrooms, 1 diced yellow onion, and 2 celery stalks cut into thin strips. Cook for 5-6 minutes until the mushrooms release their moisture and the vegetables soften slightly. Add the 3 minced garlic cloves and 1 tsp dried thyme, cooking for another 30 seconds until fragrant.
🥘 Step 3: Build the Creamy Mushroom Sauce
Sprinkle the 2 tbsp all-purpose flour over the sautéed vegetables and stir vigorously for 1 minute to remove any raw flour taste. Slowly pour in the 1 cup chicken broth while stirring constantly to prevent lumps. Bring to a gentle simmer and cook for 3-4 minutes until slightly thickened.
Reduce heat to low and stir in the 1 cup heavy cream and 1 cup grated parmesan cheese. Season with 1 tsp salt and 0.5 tsp black pepper. The sauce should coat the back of a spoon—if it's too thick, add 2-3 tablespoons of reserved pasta water to reach your desired consistency.
🍽️ Step 4: Assemble and Bake to Golden Perfection
Return the cooked chicken to the skillet and stir gently to combine. Add the cooked fettuccine pasta and toss everything together until fully coated in the creamy sauce. The mixture should look like a thick, luscious pilaf.
Transfer the skillet to a 375°F preheated oven and bake uncovered for 15-20 minutes until the top is golden brown and bubbly. For extra crispiness, broil for 1-2 minutes at the end—just watch it closely to prevent burning. The edges should be beautifully browned while the center remains creamy.
Pro Tips For Making Chicken Tetrazzini Betty Crocker
- Slice Chicken Thinly: That 1.5 lb chicken breast won’t cook evenly if it’s thick chunks—cut it against the grain into ½-inch slices before searing. I used to skip this, and half the pieces ended up dry while the rest stayed pale. A sharp knife and a little patience save you from rubbery bites later.
- Don’t Rush the Mushrooms: Let those 8 oz mushrooms sweat out their moisture for the full 5-6 minutes with the onion and celery. Skimping here means a watery sauce later. I learned this after making a batch where the mushrooms barely softened—turns out, patience here guarantees that rich, velvety texture in the finished dish.
- Whisk Like Your Life Depends on It: When you stir in the 1 cup heavy cream and 1 cup parmesan, get that whisk moving constantly for at least 30 seconds. Lumps in the sauce are the fastest way to ruin an otherwise perfect tetrazzini. I now keep a whisk handy just for this step—no more scraping globs off my teeth.
- Broil with a Watchful Eye: That final 1-2 minute broil is where the magic happens—golden crust, not burnt disaster. Start checking at 45 seconds, and if it’s not browning fast enough, give it a nudge with a spoon to concentrate the heat. Overlooking this step turns your masterpiece into a sad, pale casserole.
Common mistakes when making this recipe
Overcooking the Chicken
This is the #1 mistake I see—chicken that turns rubbery instead of tender. When you sear 1.5 lb boneless, skinless chicken breast for 4-5 minutes, it should be golden but still juicy. If you push it past 5 minutes, the outside crisps while the inside dries out.
I've learned to trust my timer and watch for white juices running clear—that's your cue to remove it. Overcooked chicken ruins the entire dish's texture. 🔥
Skipping the Pasta Water
The starchy pasta water isn't just for show—it's what makes your sauce velvety. When you reserve 1 cup of that golden liquid, you're ensuring your creamy mushroom sauce clings perfectly to the fettuccine.
I once made this dish without it, and the sauce separated like water and oil. Always save that water before draining! It's the secret to that restaurant-quality finish.
Underseasoning the Sauce
Salt and pepper are easy to overlook, but they're critical here. When you add 1 tsp salt and 0.5 tsp black pepper to the sauce, taste it before adding the pasta. If it needs more, add it now—you can't fix an underseasoned sauce later.
I've found that the cream and cheese can mask flavors if you're not careful. Trust your taste buds and adjust gradually. Your dish deserves to sing, not just exist.
Burning the Celery Crown
The celery crown is the showstopper topping, but it's also the most finicky part. If you bake it at 375°F for 8-10 minutes, it should stay crisp, not soggy. I once forgot to arrange it in a star pattern and ended up with a sad, limp pile.
Use 3-inch celery pieces and place them on top after baking the pilaf. This way, they crisp beautifully without absorbing the sauce. It's worth the extra minute of prep!
Not Letting Sauce Thicken Properly
The flour needs to cook for 1 minute before adding broth—this removes the raw taste and creates a smooth base. If you rush this step, your sauce will be thin and watery. I've seen people add the broth too quickly, creating lumps and an uneven texture.
Stir constantly and let it simmer gently for 3-4 minutes until it coats the back of a spoon. Patience here makes all the difference in your final dish.

Frequently asked questions
Can I make this recipe without heavy cream?
Replace the 1 cup heavy cream with ½ cup half-and-half plus ½ cup whole milk for a lighter texture. The sauce will still be creamy, though slightly less rich. For extra depth, stir in 1 tbsp butter at the end to compensate for the reduced fat.
How do I keep the celery crown crispy?
Arrange 3-inch celery strips in a star pattern on top of the baked pilaf, then broil for 1-2 minutes at the very end. For extra crispiness, bake the celery separately on a parchment-lined tray at 375°F for 8-10 minutes before placing it on the dish. This prevents sogginess from the sauce.
Can I use chicken thighs instead of breasts?
Yes, but adjust cooking time and method. Cut 1.5 lb boneless, skinless chicken thighs into pieces and cook for 5-6 minutes until golden and internal temp reaches 165°F. Thighs stay juicier but may require slightly longer baking time (20-25 minutes) since they're more forgiving than breasts.
Why did my sauce separate?
This usually happens when you don't cook the 2 tbsp flour for 1 minute before adding broth, or if you didn't reserve the starchy pasta water. For a quick fix, whisk in 1 tbsp cold butter or 1 tbsp flour mixed with 2 tbsp cold water while stirring constantly over low heat until smooth.
What's the best way to reheat leftovers?
Gently warm in a skillet over low heat with 2-3 tbsp milk or broth to loosen the sauce. For crispy celery crown, add it fresh after reheating. Microwaving works in a pinch, but expect the celery to soften. Leftovers keep their best texture for 2-3 days in the fridge.
