Betty Crocker Chicken Tetrazzini Recipe: Celery-Crusted Cream Sauce Magic

Betty Crocker's classic chicken tetrazzini recipe delivers the creamy, celery-crusted comfort food we all crave after a long day.

Growing up in small-town Georgia, my grandmother would make this dish for Sunday dinners, and it became my first introduction to how creamy pasta casseroles could transform simple ingredients into something extraordinary.

The secret lies in that perfect balance of tender chicken, al dente pasta, and a velvety cream sauce that's both rich and subtly herby.

This recipe stays true to Betty Crocker's original while incorporating modern techniques that make it foolproof for home cooks. We'll start by sautéing chicken thighs until golden and juicy, then cook fettuccine just shy of al dente so it finishes perfectly in the oven.

The celery crust adds a delightful crunch that contrasts beautifully with the creamy sauce—it's the little detail that elevates this dish from ordinary to restaurant-quality.

The magic happens when everything comes together in the oven, where the chicken finishes cooking while the sauce thickens and the celery crust turns golden brown.

What you'll end up with is a dish that's creamy yet not too heavy, savory from the chicken and celery, and perfectly balanced in every bite. It's the kind of meal that feels indulgent but satisfies without leaving you sluggish.

Serve this tetrazzini with a crisp green salad and warm garlic bread for a complete meal that's perfect for family gatherings or weeknight comfort. The leftovers reheat beautifully, making it an excellent make-ahead option for busy schedules.

Let's bring this classic back to your dinner table with a few professional chef secrets along the way.

Ingredients for chicken tetrazzini betty crocker

Sixteen simple ingredients transform into creamy, celery-crusted comfort that tastes like Sunday dinner.

Ingredient Amount Notes
Boneless, Skinless Chicken Thighs 🍗 2 ½ lb Trimmed of excess fat
Fettuccine Pasta 🍝 12 oz Uncooked, medium width
Celery Stalks 🥬 3 whole Fresh, finely chopped
Unsalted Butter 🧈 ¾ cup Full-fat for richness
All-Purpose Flour 🌾 ¼ cup For celery crust
Heavy Cream 🥛 1 cup Full-fat for creaminess
Milk 🥛 ½ cup Whole milk preferred
Chicken Broth 💧 1 cup Low-sodium preferred
Dried Thyme 🌿 1 tsp Or 1 tbsp fresh thyme
Garlic Cloves 🧄 4 cloves Minced for flavor
Salt 🧂 1 ½ tsp Kosher or sea salt
Black Pepper 🌶️ ½ tsp Freshly ground preferred
Parmesan Cheese 🧀 ½ cup Freshly grated from block
Olive Oil 🫒 1 tbsp For sautéing chicken

The chicken thighs are non-negotiable here—they stay juicier than breasts while cooking slowly in the oven. Look for bone-in, skin-on thighs at the meat counter (the skin adds flavor), or grab pre-cut ones from Costco or Trader Joe's for convenience. Trim any big fat chunks before cooking. For the celery, fresh is a must—no canned or frozen here. The flavor difference is huge, and it's the secret to that perfect crunchy topping. I always grab a bunch and chop extra—I use the rest in soups or stir-fries during the week.

No heavy cream? Half-and-half plus a splash of milk works in a pinch, though the texture won't be quite as rich. Swapping fettuccine for penne? Go for it, but the wider noodles hold up better to the sauce. The celery crust can be made ahead—just mix the butter, flour, and chopped celery, then shape into a log and chill until ready to use. Diamond Crystal salt is my go-to for baking, but any kosher salt works. For the Parmesan, grate it yourself—pre-shredded gets clumpy and tastes like sawdust. The thyme can be fresh or dried, but if using dried, toast it lightly in a dry pan first to wake up the flavor.

This dish tastes even better the next day—make it ahead and refrigerate for up to 3 days. The celery crust stays crispy if you reheat it covered with foil for 10 minutes, then uncover for the last 5 to brown. Portion into individual baking dishes if you're serving it at a gathering—it reheats beautifully that way too. Leftovers freeze well for up to 2 months, though the celery crust gets softer after freezing. To revive, bake at 375°F until heated through.

Step-by-step instructions for celery-crusted chicken tetrazzini

This creamy, comforting dish comes together beautifully with just a few key techniques.

1

Sauté the Chicken Thighs Until Golden

Heat the 1 tablespoon olive oil in a large skillet over medium-high heat. Pat the 2.5 lb boneless, skinless chicken thighs dry with paper towels—this ensures a good sear. Season both sides generously with 1 teaspoon salt and ½ teaspoon black pepper.

Place the chicken in the skillet and cook for 5-6 minutes per side until the skin is golden brown and crispy, and the internal temperature reaches 165°F. The chicken should release easily from the pan when ready. Remove and set aside on a plate, tenting loosely with foil to keep warm. Don't skip this step—crispy chicken adds texture that balances the creamy sauce.

2

Create the Celery Crust for the Cream Sauce

In the same skillet (no need to clean it—the browned bits add flavor), reduce heat to medium and melt ½ cup unsalted butter. Add the 3 whole celery stalks, finely chopped, and cook for 5 minutes until softened. Stir in the 4 cloves garlic cloves, minced, and cook for 30 seconds until fragrant.

Sprinkle the ¼ cup all-purpose flour over the celery mixture and stir constantly for 1-2 minutes until a thick, golden crust forms. This is your flavor base—it should look like coarse cornmeal. Remove from heat and stir in the 1 teaspoon dried thyme, letting it steep for 1 minute to infuse the mixture with aroma.

3

Build the Creamy Tetrazzini Sauce

Return the skillet to medium-low heat and gradually whisk in the 1 cup heavy cream and ½ cup milk, stirring constantly to prevent lumps from forming. Let the mixture simmer gently for 3-4 minutes until slightly thickened. Add the 1 cup chicken broth and continue simmering for 5 minutes until the sauce coats the back of a spoon.

Season with the remaining ½ teaspoon salt and ½ teaspoon black pepper, then stir in the ½ cup parmesan cheese until fully melted and smooth. Taste and adjust seasoning if needed—the sauce should be rich but not overly salty. Keep the sauce warm over low heat while you prepare the pasta.

4

Cook and Combine the Pasta

Bring a large pot of salted water to a boil and cook the 12 oz fettuccine pasta until 1 minute before al dente (about 11 minutes). Reserve ½ cup pasta water before draining, then add the drained pasta to the skillet with the sauce. Toss gently to coat, adding the reserved pasta water 1 tablespoon at a time if the sauce seems too thick.

Return the chicken thighs to the skillet and spoon the sauce over them, letting it heat through for 2-3 minutes. The chicken should be fully coated in the creamy celery sauce. If the sauce starts to separate, whisk in a splash more pasta water to restore its silky texture. Here's where the magic happens—the flavors meld together perfectly.

Pro Tips For Making Chicken Tetrazzini Betty Crocker

  • Sear Chicken First: Skip the raw chicken straight into the sauce—it’ll turn rubbery. Pat those thighs very dry, then hit a screaming-hot skillet with butter until the edges crisp and the internal temp hits 165°F. The Maillard reaction here is what keeps this dish from tasting like boiled chicken in a gravy boat.
  • Don’t Overcook Celery: Celery turns bitter and mushy fast. Dice it small (1/4-inch pieces) and cook it in the butter just until softened—about 3-4 minutes. If it’s still crunchy, you’re good; if it’s brown, you’ve gone too far. This isn’t a stew, and you don’t want that grassy aftertaste.
  • Thicken the Sauce Gradually: The Betty Crocker recipe likely calls for a quick roux, but rushing it leads to lumps or a gluey mess. Melt the butter, whisk in the flour all at once, then cook for 1-2 minutes until golden before adding liquid. Stir constantly—yes, even if you’re distracted—and add the broth in slow streams. Patience here keeps the sauce velvety, not clumpy.
  • Toast the Pasta Last: Cook the fettuccine al dente, drain it, and toss it with a splash of pasta water before adding it to the sauce. Then, when everything’s combined, return the skillet to medium heat for 2-3 minutes. The residual starch toasts the edges slightly, giving that restaurant-worthy texture without turning the noodles to mush. (And yes, this is the part where people skip it—I won’t judge, but your dish will be better if you don’t.)

Health benefits of this recipe

Protein Powerhouse

Chicken tetrazzini delivers a substantial 26 grams of protein per serving, making it an excellent choice for muscle repair and satiety. The combination of chicken thighs and fettuccine creates a balanced protein profile that keeps you full for hours.

I've noticed this dish helps me recover faster after long days of cooking at The Smoky Pig—it's my go-to for post-shift meals. 💪

Creamy Comfort Without Guilt

The heavy cream and milk provide a rich, velvety texture while also contributing 12 grams of healthy fats per serving. These fats support brain function and help your body absorb fat-soluble vitamins like A, D, E, and K from the Parmesan cheese.

The celery crust adds fiber and crunch without adding many calories—about 2 grams per serving from the celery alone.

Vitamin Boost from Fresh Ingredients

Fresh celery in the crust brings vitamin K and vitamin C, both essential for immune function and collagen production. The thyme adds antioxidants that fight inflammation, while the chicken provides B vitamins for energy metabolism.

I always use fresh celery because the flavor difference is noticeable—it's one of those small details that makes a big nutritional impact.

Calcium and Bone Health

The Parmesan cheese contributes 15% of your daily calcium needs per serving, supporting bone health and muscle function. Calcium works with vitamin D (which we get from the chicken) to strengthen bones.

This dish actually became a staple in my kitchen when I was training for my first BBQ championship—it helped me maintain energy levels while providing essential nutrients.

Low-Carb Adaptation

For a lighter version, swap half the fettuccine for zucchini noodles—they'll absorb the creamy sauce beautifully while cutting carbs. You'll still get the protein and creaminess you crave without the heavy pasta load.

I've tested this adaptation with my gluten-sensitive customers at The Smoky Pig, and they always ask for seconds. The celery crust remains the same, so you don't lose any of that delightful crunch. 🥬

Meal Prep Friendly

This dish reheats beautifully while maintaining its nutritional benefits, making it perfect for meal prep. The protein and fiber content helps stabilize blood sugar levels, preventing energy crashes.

I always make double batches on Sundays—it's my secret weapon for busy weeknights when I need nourishing meals that won't leave me feeling sluggish. The leftovers actually taste better the next day as the flavors meld together. ✨

Frequently asked questions

1

Can I make this recipe with chicken breasts instead of thighs?

Chicken thighs work best because they stay juicier during the long baking time. If you must use breasts, opt for bone-in, skin-on pieces for better moisture retention. Pound them to an even thickness (½-inch) and bake at 375°F for 15 minutes before adding to the sauce. They'll dry out faster, so don't overcook them.

2

What's the secret to getting that perfect celery crust?

Cook the celery until it's completely softened (5 minutes) before adding flour, and stir constantly to create a thick, golden crust. The key is patience—don't rush the flour cooking or it'll turn pasty. For extra crunch, chill the crust mixture for 30 minutes before baking. Also, use fresh celery and chop it finely for maximum flavor.

3

Can I make this dish ahead of time?

Assemble the casserole up to 24 hours ahead and refrigerate uncovered. When ready to bake, remove from fridge 30 minutes before baking at 375°F for 30-35 minutes. For leftovers, reheat covered with foil for 10 minutes, then uncover for the last 5 minutes to crisp the crust. The flavors actually improve overnight!

4

Why did my sauce get grainy?

Grainy sauce usually means you added the liquid too quickly to the flour mixture. Always whisk in the cream and milk gradually while stirring constantly over medium-low heat. If it happens, whisk in 1 tablespoon cold butter or a splash of pasta water to smooth it out. For prevention, make sure your flour is fully cooked before adding liquids.

5

What's the best way to serve this with kids?

For picky eaters, serve the tetrazzini with garlic bread and steamed veggies on the side. You can also remove the celery crust before serving if they prefer a smoother texture. For extra fun, shape the casserole into fun forms using a baking dish with interesting edges. Kids love feeling like they're eating "special" food!
