Ingredients for luby’s chicken tetrazzini

Sixteen ingredients transform into Luby’s legendary creamy, cheesy comfort—no shortcuts, just restaurant-quality flavor.

The chicken and mushrooms are the flavor anchors here. Chicken breast needs to be pounded to even thickness—about 1/4-inch—for consistent cooking. White button mushrooms work best (cremini adds depth but costs more), and you’ll want to slice them uniformly so they cook evenly. For the pasta, fettuccine is traditional, but pappardelle or tagliatelle will work too. The cheese matters—sharp cheddar from a block (like White Cheddar) melts better than pre-shredded. Costco or Whole Foods usually carry the best blocks, and if you’re feeling fancy, a mix of Gruyère and cheddar takes it to next level.

No white wine? Chicken broth plus a splash of lemon juice works perfectly—just add 1/2 tsp lemon juice per cup of broth. The flour should be all-purpose, not cake flour, for that proper roux texture. For the butter, European-style (like Plugrá) has higher fat content, which gives you a richer sauce. Short on thyme? Dried marjoram at half the amount is a decent swap, though it won’t be identical. The garlic can be roasted ahead of time for a sweeter flavor—just toss whole cloves with olive oil, roast at 400°F for 10 minutes, then peel and mince. Trader Joe’s sells pre-minced garlic in tubes that’s perfect for this.

This dish reheats beautifully—just cover with foil and warm in the oven at 350°F for 15 minutes. For leftovers, store in an airtight container with a layer of parchment paper between layers to prevent sogginess. Keeps for 4-5 days in the fridge or 3 months frozen. The sauce thickens as it cools, so you can always thin it with a splash of milk or broth when reheating. If you’re making this ahead for a party, assemble it in the pan, refrigerate overnight, then bake straight from the fridge—just add 5-10 minutes to the baking time.

Step-by-step instructions for Luby’s chicken tetrazzini

This one-pan masterpiece delivers rich, creamy perfection with tender chicken and mushrooms.

Bring a large pot of water to a rolling boil and add 12 oz fettuccine pasta. Stir immediately to prevent sticking, then add 1.5 tsp salt and 1 tsp black pepper. Cook the pasta for 1 minute less than the package instructions suggest for al dente texture—it’ll finish cooking in the oven. Reserve 1 cup pasta water before draining, as this starchy liquid is essential for creating a velvety sauce.

While the pasta cooks, prepare the chicken by pounding the 2.5 lb boneless, skinless chicken breast between two sheets of plastic wrap to an even ½-inch thickness. This ensures even cooking and prevents dryness. Season both sides generously with ½ tsp salt and ½ tsp black pepper. Set aside until ready to use.

In a large oven-safe skillet, melt ½ cup unsalted butter over medium heat. Add the 1 whole yellow onion, diced, and cook for 5 minutes until softened. Stir in the 6 cloves garlic cloves, minced, and cook for 1 minute until fragrant—don’t let it brown or it’ll turn bitter.

Add the 1.5 lb white button mushrooms, sliced, and cook for 8-10 minutes until they release their moisture and begin to brown. Sprinkle in the 0.25 cup all-purpose flour and stir vigorously for 1 minute to create a roux. Slowly pour in the 0.5 cup dry white wine and 1 cup chicken broth, stirring constantly to prevent lumps. Let the mixture simmer for 3 minutes until slightly thickened.

Add the 2.5 lb boneless, skinless chicken breast to the skillet, arranging the pieces in a single layer. Pour in the 1.5 cups heavy cream and 0.5 cup whole milk, then sprinkle the 2 cups shredded sharp cheddar cheese and 0.5 cup parmesan cheese evenly over the top. The cheese should melt into the sauce, creating a luscious, creamy coating.

Increase the heat to medium-high and bring the mixture to a gentle simmer. Cook for 5-7 minutes, stirring occasionally, until the chicken is cooked through and reaches an internal temperature of 165°F. The sauce should thicken slightly but remain silky smooth. If it becomes too thick, stir in 2-3 tablespoons of reserved pasta water to reach your desired consistency.

Gently fold in the cooked 12 oz fettuccine pasta and the 0.5 tsp dried thyme until everything is evenly coated in the creamy mushroom sauce. Transfer the skillet to a 375°F preheated oven and bake, uncovered, for 15-20 minutes. You’ll know it’s done when the top is golden brown and bubbly, and the cheese has melted into a glossy, creamy layer.

Let the tetrazzini rest for 5 minutes before serving to allow the sauce to set slightly. The result should be a rich, creamy dish with tender chicken, earthy mushrooms, and a perfectly balanced blend of cheeses. Serve immediately with a side of garlic bread to soak up every last bit of that luscious sauce.

Best sauces and condiments for this luby’s chicken tetrazzini

Creamy Cheese Sauce

The heart of this dish is the velvety cheese sauce made with sharp cheddar and parmesan. I recommend using freshly grated cheese from a block—it melts more smoothly than pre-shredded. For extra richness, I add ½ cup heavy cream and ½ cup whole milk to create a luxurious texture.

If you want to deepen the flavor, stir in 1 tbsp Dijon mustard at the end for a subtle tang that cuts through the richness. 🧀

Mushroom Depth

The earthy flavor of mushrooms is essential for balancing the creaminess. I use white button mushrooms because they’re mild and consistent, but cremini or shiitake add more complexity. Sauté them until they release their moisture and develop a golden-brown crust—this builds flavor.

For an extra boost, I toss in 1 tsp soy sauce during the sautéing to add umami depth. 🍄

Garlic-Infused Butter

Start the sauce with ½ cup unsalted butter infused with 6 minced garlic cloves. Cook the garlic just until fragrant—about 1 minute—to avoid bitterness. For a sweeter garlic flavor, I roast whole garlic cloves at 400°F for 10 minutes before mincing.

This technique adds a subtle sweetness that complements the creamy sauce beautifully. 🧄

Wine Reduction

Deglaze the pan with ½ cup dry white wine after cooking the mushrooms to create a flavorful reduction. If you don’t have wine, substitute with chicken broth plus ½ tsp lemon juice.

Simmer the liquid until it reduces by half to intensify the flavor. This step adds complexity that makes the sauce taste restaurant-quality. 🍷

Pasta Water Magic

Reserve 1 cup pasta water when draining the fettuccine—it’s a game-changer for the sauce. The starch in the water helps emulsify the cheese and creates a silky texture. If the sauce thickens too much during baking, stir in 2-3 tablespoons of reserved pasta water to restore creaminess.

This trick keeps the sauce luscious without diluting the flavor. 💧

Herb Finishing

Finish the dish with ½ tsp dried thyme or 1 tsp fresh chopped thyme for an aromatic touch. For extra brightness, I sprinkle 1 tbsp fresh parsley on top before serving.

A pinch of red pepper flakes adds subtle heat, while a drizzle of truffle oil elevates the dish to gourmet status. 🌿
