Betty Crocker Chicken Tetrazzini Recipe: One-Pan Creamy Pasta Bake Magic

Betty Crocker’s chicken tetrazzini recipe delivers that comforting, creamy pasta bake magic in one pan—just like my grandmother used to make. The secret lies in perfectly sautéed chicken, al dente pasta, and a rich mushroom sauce that ties everything together.

Growing up in small-town Georgia, I learned how layering ingredients and baking until golden transforms simple components into a showstopper dish. This recipe stays true to Betty Crocker’s classic technique while making it approachable for home cooks.

The beauty of this dish is its foolproof method—no fancy equipment needed, just a cast-iron skillet or baking dish. You’ll start by searing chicken thighs for flavor, then cook fettuccine until al dente before tossing it with a velvety mushroom cream sauce.

The layers of pasta, chicken, and sauce create texture and depth, while baking until bubbly and golden ensures that creamy, restaurant-quality finish. It’s the kind of dish that feeds a crowd but still feels special enough for a weeknight dinner.

What makes this recipe stand out is the balance of flavors—savory chicken, earthy mushrooms, and that rich, creamy sauce that clings to every strand of pasta.

The browning step at the end adds a satisfying crispness to the top layer, while fresh parsley or grated Parmesan adds a pop of color and freshness. This is comfort food at its finest, with just the right amount of effort to feel rewarding without being overwhelming.

Perfect for family dinners, potlucks, or when you want to impress guests without stressing over complicated techniques. The best part? Leftovers reheat beautifully, making it a meal that gives back. Let’s get started on this creamy, hearty classic that’s been a staple for generations.

Ingredients for chicken tetrazzini betty crocker

Sixteen ingredients transform into Betty Crocker’s legendary creamy chicken tetrazzini—comfort food at its finest.

The chicken thighs are non-negotiable here—they stay juicy while rendering fat for flavor. Look for bone-in, skin-on pieces at your local butcher or grocery store's meat counter, as they deliver the best texture and depth. If you can't find bone-in, skin-on thighs, bone-in skinless works, but expect slightly less crispiness. The mushrooms should be firm and white, not slimy or discolored—Trader Joe's or Whole Foods often carry high-quality white mushrooms in bulk. For the pasta, De Cecco or Barilla fettuccine are reliable choices that hold up well to the creamy sauce without turning mushy.

No sherry? Dry white wine or additional chicken broth works perfectly—just reduce the broth by half to maintain balance. For the roux, unsalted butter and all-purpose flour are essential—substituting margarine or gluten-free flour will alter the texture. If you're avoiding dairy, heavy cream can be replaced with coconut cream or cashew cream, though the sauce will have a slightly different mouthfeel. The garlic should be freshly minced for the best flavor, but if you're short on time, garlic powder at half the amount will suffice in a pinch. For the Parmesan, grate it yourself from a wedge—pre-grated cheese contains anti-caking agents that prevent proper melting.

This dish reheats beautifully—cover with foil and bake at 350°F for 15-20 minutes to restore creaminess. Store leftovers in an airtight container for up to 4 days in the fridge, or freeze for 3 months by portioning into individual servings. The sauce thickens as it cools, so add a splash of broth or cream when reheating if it seems too stiff. For meal prep, assemble the dish ahead of time and refrigerate unbaked—add 10-15 minutes to baking time when ready to serve.

Step-by-step instructions for creamy chicken tetrazzini

This one-pan method delivers rich, velvety sauce and perfectly cooked pasta every time.

Heat a large oven-safe skillet over medium-high heat. Add the 1.5 lb chicken thighs, skin-side down, and cook for 5-6 minutes until golden brown. Flip and cook another 4-5 minutes until internal temperature reaches 165°F. Remove chicken and set aside.

In the same skillet, add the 0.5 cup unsalted butter and let it melt completely. Add the diced 1 whole yellow onion and sliced 1 lb white mushrooms. Cook for 5-6 minutes until mushrooms release their moisture and onions soften. Stir in the 4 cloves minced garlic and cook for 30 seconds until fragrant. Sprinkle with 0.5 tsp garlic powder and season with 0.5 tsp salt and 0.5 tsp black pepper.

Reduce heat to medium and sprinkle the 0.25 cup all-purpose flour over the mushroom mixture, stirring constantly for 1-2 minutes to cook off the raw flour taste. Gradually whisk in the 1 cup heavy cream and 1 cup chicken broth, stirring until smooth. Add the 0.25 cup dry sherry and bring to a gentle simmer.

Let the sauce thicken for 3-4 minutes until it coats the back of a spoon. Return the cooked chicken to the skillet, spooning the sauce over it. Nestle the 12 oz fettuccine pasta around the chicken, ensuring each strand is well-coated with sauce. Cover and let sit off heat for 5 minutes to absorb initial flavors.

Preheat your oven to 375°F. Transfer the skillet to the oven and bake uncovered for 20-25 minutes. You'll know it's done when the pasta is tender and the top is bubbly with golden brown spots. If the sauce looks too thick, add 2-3 tablespoons of water or broth to loosen it.

Here's the thing—this is the moment that matters: the sauce should be creamy but not watery, clinging beautifully to the pasta and chicken. If you're worried about overcooking, check the pasta at the 20-minute mark. It should be al dente with just a slight bite remaining.

Remove from oven and let rest for 5 minutes. This resting period allows the juices to redistribute throughout the dish, ensuring each bite is rich and flavorful. Sprinkle the top evenly with the 0.5 cup freshly grated parmesan cheese and the 0.25 cup chopped fresh parsley.

For that final touch, I like to broil for 1-2 minutes until the cheese melts and turns golden brown. Watch it closely to prevent burning. The result should be a perfectly creamy, cheesy topping that ties everything together. Serve immediately with a side of garlic bread to soak up every last bit of that luxurious sauce.

Essential equipment for this recipe

Oven-Safe Skillet

An oven-safe skillet is your best friend for this recipe—I swear by my Lodge 12-inch cast iron for its even heat distribution and durability. If you don’t have cast iron, a stainless steel skillet like All-Clad works perfectly.

Just ensure it’s oven-safe up to 450°F. For larger gatherings, a 9x13-inch baking dish lets you double the recipe without sacrificing texture. 🔥

Wooden Spoon

A wooden spoon is essential for stirring the roux and sauce without scratching your skillet. I keep a Oxo Good Grips in my kitchen—it’s sturdy and won’t warp from heat.

Avoid metal spoons during the roux stage to prevent lumps. For scraping up those last bits of sauce, a flexible silicone spatula comes in handy.

Fine-Mesh Strainer

If your chicken broth has visible fat or impurities, a fine-mesh strainer ensures a smooth sauce. I use a stainless steel colander with tight weave for this purpose. For homemade broth, straining is non-negotiable—it keeps the sauce velvety. Skip this step only if using store-bought low-sodium broth that’s already filtered.

Kitchen Scale

While measuring by volume works, a digital kitchen scale guarantees precision, especially for the roux and sauce ratios. My OXO Good Grips scale measures in both grams and ounces—perfect for adjusting recipes.

For the flour, weighing ensures the sauce thickens properly without gluten clumping. If you’re measuring flour by cup, spoon it in gently and level off the top.

Mixing Bowls

Medium and large stainless steel mixing bowls help organize prep steps. I use a nesting set for layering ingredients—one for the sauce, another for chopped mushrooms, and a third for the pasta.

Glass bowls work too, but metal conducts heat better if you’re prepping ahead. Keep them nearby to avoid cross-contamination with raw chicken juices.

Cheese Grater

Freshly grated Parmesan cheese makes all the difference—pre-grated cheese contains anti-caking agents that prevent proper melting. My Microplane grater delivers fine, even shreds without clumping. For a coarser texture, a box grater works, but it’s messier. Grate the cheese right before serving to preserve its sharp flavor and aroma. 🧀
