Betty Crocker's Chicken Tetrazzini Recipe: Crispy Celery Crown Over Mushroom Cream Bliss

Betty Crocker’s chicken tetrazzini delivers that comforting, creamy, crispy-topped magic we all crave when weeknights call for something special. 🌟 Growing up in small-town Georgia, I learned how a simple casserole could transform a humble dinner into a family gathering centerpiece—this recipe does exactly that, with tender chicken, rich mushroom sauce, and that iconic celery crown that turns golden perfection.

The secret lies in balancing textures: crispy celery topping meets velvety mushroom cream sauce, all baked until bubbly and golden. I’ve refined Betty Crocker’s classic method to ensure the chicken stays juicy while the pasta absorbs the sauce perfectly—no soggy bottoms here.

This dish is restaurant-quality without the fuss, making it ideal for feeding a crowd or enjoying a homemade comfort meal.

By the time it emerges from the oven, you’ll have a dish that’s creamy yet crispy, savory yet satisfying—every bite delivers layers of flavor. The celery crown adds a satisfying crunch that contrasts beautifully with the tender chicken and creamy sauce underneath.

It’s the kind of meal that feels indulgent but still fits into a weeknight routine.

Serve with a simple green salad or crusty bread to soak up every last drop of that rich mushroom cream sauce. Here’s how to make it—step by step—for a dish that’s as impressive as it is delicious. Let’s get cooking!

Ingredients for chicken tetrazzini betty crocker

Pantry staples meet restaurant magic—creamy, crispy, and packed with comfort.

The celery crown is what makes this dish iconic. Use firm, crisp celery stalks—the darker green ones near the base work best. Trim off the stringy ends and slice them thin so they crisp up perfectly. For the mushrooms, cremini or baby bella add extra richness, but white mushrooms still work. I always grab mine at Whole Foods or the grocery store's produce section—just make sure they're fresh and not slimy. The chicken should be cut into even strips so it cooks through without drying out. If you're short on time, pre-cut chicken breast strips from the deli counter save a step.

No sherry? Dry white wine or extra chicken broth works perfectly—just add a splash of lemon juice to mimic the acidity. Running low on heavy cream? Half-and-half plus a splash of milk keeps it creamy without breaking the bank. For the pasta, fettuccine is traditional, but any medium-width pasta like pappardelle or tagliatelle works. The flour needs to be all-purpose—bread flour makes the sauce too thick. If you're making this ahead, cook the pasta al dente so it finishes perfectly in the oven. And trust me, freshly grated Parmesan makes all the difference—pre-grated gets clumpy and lacks flavor.

This dish tastes even better the next day once all the flavors meld. Store leftovers in an airtight container in the fridge for up to 4 days. For the celery crown, assemble it right before baking so it stays crispy. If you're making this for a crowd, double the celery topping—it disappears fast. The sauce reheats beautifully, so portion it out for easy lunches. Freezes well for up to 3 months, though the celery crown gets soggy if frozen—make that fresh each time.

Step-by-step instructions for chicken tetrazzini

Here's how to create that perfect balance of crispy celery crowns and creamy mushroom sauce.

Heat a large skillet over medium-high heat and add 2 tablespoons of the 0.5 cup unsalted butter (reserve the rest for later). Add the 2.5 lb boneless, skinless chicken breast cut into 1-inch strips and cook for 5-6 minutes until the chicken is golden brown on all sides and cooked through to 165°F internally.

Here's the thing—don't overcrowd the pan. Cook the chicken in batches if needed to maintain even browning. Season each batch with 0.5 tsp salt, 0.25 tsp ground black pepper, and 0.25 tsp dried thyme (half the total amounts). Once fully cooked, remove the chicken and set it aside on a plate.

In the same skillet, reduce heat to medium and add the remaining 0.33 cup unsalted butter (about ⅔ of what you started with). Add the 1 whole yellow onion (diced small) and cook for 3-4 minutes until softened. Add the 16 oz fresh white mushrooms (sliced into ¼-inch pieces) and cook for another 4-5 minutes until they release their moisture and begin to brown.

Add the 3 whole celery stalks (trimmed and cut into ¼-inch slices) and the 4 cloves garlic cloves (minced fine). Cook for 2-3 minutes until the celery is tender and the garlic is fragrant. You'll know it's ready when the mixture smells like a cozy autumn forest—this is where all the deep flavors develop.

Sprinkle the 0.25 cup all-purpose flour over the vegetable mixture and stir vigorously for 1-2 minutes until the flour is fully incorporated and the mixture turns into a thick paste. This step is crucial—it removes any raw flour taste and creates the velvety base for your sauce.

Gradually pour in the 1.5 cups chicken broth while stirring constantly to prevent lumps. Add the 0.5 cup dry sherry and bring the mixture to a gentle simmer. Let it cook for 5 minutes until slightly thickened. Then, stir in the 1 cup heavy cream and simmer for another 3-4 minutes until the sauce coats the back of a spoon.

While the sauce simmers, bring a large pot of salted water to a boil and cook the 12 oz uncooked fettuccine pasta according to package directions until al dente (about 1 minute less than recommended). Drain and set aside, reserving ½ cup of the pasta water.

In a separate skillet, melt 2 tablespoons of the remaining 0.5 cup unsalted butter over medium heat. Add the drained pasta and toss to coat evenly. Sprinkle with 0.5 tsp salt and 0.25 tsp dried thyme, then transfer to a serving dish. Here's the magic: arrange the pasta in a circular pattern, then place the cooked chicken strips on top in a circular pattern as well. This creates that beautiful "crown" effect that makes this dish so special.

Pour the creamy mushroom sauce over the chicken and pasta arrangement. The sauce should cover everything completely—if it looks too thick, add 1-2 tablespoons of the reserved pasta water to loosen it. Sprinkle the 0.5 cup parmesan cheese evenly over the top and the remaining 0.25 tsp ground black pepper.

Transfer the dish to a 375°F preheated oven and bake for 10-12 minutes until the top is golden brown and bubbly. The cheese will melt into a delicious blanket, and the celery crown will achieve that perfect crispy texture at the edges. Let it rest for 5 minutes before serving to allow the sauce to set slightly.

Storing and reheating this chicken tetrazzini betty crocker

Refrigerator Storage

Let your tetrazzini cool completely to room temperature before storing—this prevents condensation that makes the celery crown soggy. Transfer to an airtight glass container (I prefer Pyrex with a tight-sealing lid) and refrigerate for up to 4 days.

The flavors actually deepen overnight as the sauce melds with the pasta and chicken. Honestly, this is when it tastes best—the next-day version always gets rave reviews at my farm gatherings. ❄️

Freezer Prep Tips

For longer storage, freeze the assembled dish (before baking) in a freezer-safe plastic container with 1-inch headspace—this prevents ice crystals from breaking the celery crown. I wrap the container tightly in plastic wrap first, then place it in the freezer.

Thaw overnight in the fridge before baking—never microwave directly from frozen or the celery will turn mushy. The sauce reheats beautifully, though the celery crown loses its crispiness after freezing.

Stovetop Reheating

My preferred method for restaurant-quality results: Transfer portions to a heavy-bottomed skillet (I use my Lodge cast iron) and warm over medium-low heat with 2-3 tablespoons of water or chicken broth. Cover and heat for 8-10 minutes, stirring occasionally, until bubbly.

The key is gentle heat—this prevents the sauce from breaking or the celery from burning. Add a splash of heavy cream if it looks too thick after reheating. 🔥

Oven Finish Trick

For that crispy celery crown texture after reheating, transfer the dish to a 400°F oven for the final 3-5 minutes. This creates a golden, crispy top without drying out the sauce underneath. I often do this when serving to a crowd—it’s a game-changer for presentation.

If using leftovers, assemble fresh celery crowns on top before the oven finish for maximum crispiness. The contrast of warm creamy sauce and crispy celery is what makes this dish unforgettable.

Microwave Shortcut

For quick lunches, microwave individual portions on 50% power for 2-3 minutes, stirring halfway. Cover with a damp paper towel to prevent drying. If the sauce looks too thick, add 1 tablespoon of water or broth and microwave for another 30 seconds.

The celery crown won’t be crispy, but the flavors stay rich and comforting. This is my go-to for busy weeknights when I’m short on time. 💡

Make-Ahead Crown

Here’s my pro tip: Prepare the celery crown separately and assemble it fresh before baking or reheating. Store the main dish (without the crown) in the fridge or freezer, then add fresh celery slices and Parmesan just before serving or baking.

This keeps the texture perfect every time. I do this when feeding a crowd—it’s the secret to restaurant-quality results at home. The crown only needs 5-7 minutes in a 400°F oven to crisp up beautifully.
