Betty Crocker Chicken Tetrazzini Recipe: One-Pan Creamy Mushroom Magic

Betty Crocker’s chicken tetrazzini delivers that comforting, creamy magic in one pan—no fuss, just rich, cheesy layers of tender chicken and mushrooms baked to perfection.

Growing up in small-town Georgia, I learned how a simple casserole could transform a weeknight into a celebration, and this recipe does exactly that with restaurant-quality ease.

The secret lies in the velvety sauce that clings to every strand of pasta and bite of chicken, creating a dish that’s equal parts hearty and indulgent.

What makes this recipe stand out is its foolproof method—just layer cooked chicken, mushrooms, and pasta in a baking dish, then pour on the creamy sauce before baking. The mushrooms release their earthy flavors as they soften, while the cheese melts into a golden, bubbly crust.

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.

By the time it emerges from the oven, you’ll have a dish that’s creamy, cheesy, and impossible to resist—each forkful packed with tender chicken, mushrooms, and that signature creamy sauce.

The aroma alone will have everyone gathering around the table, and the first bite will remind them why comfort food is worth the effort. Ready in just 45 minutes, this recipe proves you don’t need a complicated process to create something extraordinary.

Pair it with a simple green salad or crusty bread to soak up every last drop of that rich sauce. Here’s how to make it—just follow the steps, and let the oven do the rest.

Ingredients for chicken tetrazzini betty crocker

Sixteen ingredients transform into Betty Crocker’s legendary creamy chicken tetrazzini masterpiece.

The chicken breasts are the foundation—look for plump, evenly sized pieces at the meat counter, and pound them to even thickness for consistent cooking. Costco or Whole Foods carry high-quality cuts, but any supermarket’s fresh chicken works fine. For the mushrooms, cremini or baby bella add deeper flavor than white mushrooms, but don’t stress if that’s what’s available. The onions should be crisp and white—yellow or sweet onions add unwanted sweetness to this dish. Pre-sliced mushrooms and onions save time, but fresh is always better for this creamy dish.

No sherry on hand? Dry white wine or extra chicken broth works perfectly—just add a splash of lemon juice to mimic the acidity. The cheese matters here: sharp cheddar melts best, while pre-shredded often contains anti-caking agents that prevent proper melting. Freshly grating the Parmesan makes all the difference. For the pasta, fettuccine or pappardelle work best—the wider noodles hold the creamy sauce beautifully. If you can’t find dry sherry, Trader Joe’s carries a decent substitute in their wine section, or use apple cider vinegar at half the amount for tang.

This casserole tastes even better the next day—reheats beautifully from the fridge or frozen. Store leftovers covered in the fridge for 4-5 days, or freeze portions for up to 3 months. For meal prep, assemble the dish ahead but bake it fresh—the sauce thickens better when baked. The cheese layer forms a perfect crust when baked straight from the fridge, so no need to thaw before serving. Double the recipe for a crowd—it’s always a hit at gatherings.

Step-by-step instructions for Betty Crocker chicken tetrazzini

This one-pan method delivers perfectly cooked chicken and al dente pasta in a velvety mushroom sauce.

Begin by pounding the 2.5 lb boneless, skinless chicken breast to an even ½-inch thickness between two sheets of plastic wrap. Season both sides generously with 1 tsp of the 1.5 tsp salt and ¼ tsp of the 0.5 tsp black pepper.

In a separate bowl, combine the 12 oz fettuccine pasta with 1 tbsp of the 2 tbsp all-purpose flour. Toss gently to coat the strands lightly—this prevents clumping when cooked. Set aside until ready to use.

Heat 2 tbsp of the 4 tbsp butter in a large oven-safe skillet over medium-high heat until foaming. Add the pounded chicken and cook for 4-5 minutes per side until golden brown and cooked through to an internal temperature of 165°F. Remove the chicken and set aside on a plate.

In the same skillet, melt the remaining 2 tbsp butter. Add the 1 whole yellow onion (thinly sliced) and cook for 3-4 minutes until softened. Stir in the 4 cloves garlic (minced) and cook for 30 seconds until fragrant. Add the 1.5 lb white mushrooms (sliced) and cook for 5-6 minutes until golden and tender.

Sprinkle the 2 tbsp all-purpose flour over the mushrooms and stir for 1-2 minutes to cook out the raw flour taste. Gradually whisk in the 0.5 cup dry sherry and the 1 cup chicken broth, stirring constantly to prevent lumps. Let the mixture simmer for 3-4 minutes until slightly thickened.

Reduce heat to medium-low and stir in the 1 cup heavy cream. Add the 2 cups shredded cheddar cheese and 0.5 cup parmesan cheese, stirring until fully melted and smooth. The sauce should coat the back of a spoon with a velvety consistency.

Return the cooked chicken to the skillet and spoon the creamy sauce over the top. Add the floured fettuccine pasta, tossing gently to coat each strand evenly. The pasta should be submerged in the sauce but not overly soggy.

Cover the skillet and transfer to a preheated 375°F oven. Bake for 20-25 minutes, stirring once halfway through, until the pasta is tender and the sauce has thickened to a creamy consistency. The top should be golden and bubbly.

Remove the skillet from the oven and let the tetrazzini rest for 5 minutes. This allows the sauce to set slightly and makes serving easier. Garnish with additional black pepper if desired.

Serve immediately in individual portions, ensuring each serving contains both chicken and pasta. The creamy mushroom sauce should cling beautifully to the al dente fettuccine and tender chicken, delivering that rich, comforting texture promised in the title.

Wine and beer pairings for this chicken tetrazzini betty crocker

Creamy White Wine Pairing

This dish practically begs for a Chardonnay—specifically a buttery, oak-aged one from California like Louis M. Martini’s Private Reserve. The wine’s vanilla and caramel notes mirror the richness of the creamy sauce, while its acidity cuts through the heaviness.

I’ve found that a 2018 Russian River Valley Chardonnay from Kendall-Jackson also works beautifully—it’s crisp enough to refresh your palate between bites of that velvety tetrazzini. 🍷

Crisp Sauvignon Blanc

For a lighter option, a Sauvignon Blanc from New Zealand like Oyster Bay brings bright citrus and herbal notes that complement the earthy mushrooms. The wine’s zesty acidity balances the dish’s creaminess without overwhelming it.

I often reach for a bottle of Cloudy Bay when I want to keep the meal feeling fresh and vibrant. This pairing is perfect for warmer evenings when you don’t want to feel too heavy after dinner.

Malbec for Bold Lovers

If you prefer red wine, a Malbec from Argentina such as Catena Zapata delivers rich dark fruit flavors that stand up to the dish’s cheesy sauce. The wine’s soft tannins won’t clash with the creamy texture, and its plum and chocolate notes add depth to the meal.

I’ve served this pairing at dinner parties, and it’s always a crowd-pleaser—especially when paired with a simple arugula salad on the side. 🍷

Beer Pairings: Lager or IPA?

A crisp German Pilsner like Warsteiner or Spaten cleanses the palate beautifully between bites of the rich casserole. The beer’s hoppy bitterness balances the dish’s creaminess, while its light body prevents it from feeling too heavy.

For a craft beer option, a Belgian Witbier like Allagash White adds a refreshing citrus note that pairs surprisingly well with the mushrooms and sherry in the sauce.

Non-Alcoholic Option

For those skipping alcohol, a sparkling apple cider like Martinelli’s or a ginger beer such as Thomas Henry’s adds a fizzy contrast to the creamy dish. The ginger’s spice complements the savory mushrooms, while the apple’s tartness brightens the meal.

I often serve this at family gatherings when kids are included—it’s refreshing and still feels special. 🍏
