I've perfected this technique over years of testing—what starts as a simple assembly ends up as a rich, velvety dish that's perfect for family dinners or potlucks.

The beauty of this recipe lies in its simplicity: just one-pot, minimal prep, and a 30-minute bake that delivers restaurant-quality results.

This isn't just a casserole; it's a foolproof method that works every time, even for beginners.

Serve with a simple side salad or crusty bread to soak up every last bit of that delicious sauce. The best part? Leftovers reheat beautifully, making this the ultimate meal-prep-friendly dish. Let's get started on creating this creamy, one-pot wonder that'll become a household favorite.

Ingredients for campbell soup tetrazzini

Six ingredients make this creamy, one-pot wonder that tastes like a restaurant classic.

The Campbell's mushroom soup is the heart of this dish—don't skimp on quality. Grab the condensed version since it's easier to work with. For the chicken, boneless, skinless breasts are key—they cook evenly and stay tender. I always buy mine from Costco when I'm doing a big batch, but the regular supermarket stuff works fine. Penne pasta is ideal here because it holds up well to the baking, but rigatoni or farfalle work too. The cheese? Sharp cheddar gives that perfect tangy bite, but Gruyère or Parmesan add a fancy touch if you're feeling fancy.

No Campbell's soup? Homemade mushroom soup works—just blend cooked mushrooms, chicken broth, and a splash of cream until smooth. Chicken thighs instead of breasts? They'll stay juicier but might need less baking time. For the pasta, cook it al dente—it'll finish cooking in the oven. The garlic powder is non-negotiable—it adds that extra depth. Fresh parsley is ideal, but dried works in a pinch. If you're short on time, pre-shredded cheese is fine, but freshly grated melts better. The olive oil matters here—use something with a good fruity flavor.

This casserole reheats beautifully—honestly tastes better the next day once everything melds. Keeps for 4-5 days in the fridge, freezes for 3 months. I always make extra because it's perfect for meal prep. For a crispier topping, broil for 2-3 minutes at the end. Serve with a simple side salad or crusty bread to soak up that creamy goodness. Leftovers? Just reheat with a splash of milk to restore creaminess.

Step-by-step instructions for creamy mushroom and chicken Tetrazzini

Here's how to make this rich, creamy one-pot wonder with perfect texture every time.

Heat the 1 tablespoon olive oil in a large, deep skillet or Dutch oven over medium-high heat. Add the 2 lb boneless skinless chicken breast cut into bite-sized pieces and cook for 5-6 minutes until the chicken is lightly browned on all sides. This ensures maximum flavor extraction before the creamy sauce envelops it.

Add the 1.5 cups uncooked penne pasta and stir to coat with the olive oil. Pour in 4 cups of water (or enough to completely cover the pasta) and bring to a boil. Reduce heat to medium and simmer for 12-14 minutes, stirring occasionally, until the pasta is al dente and the chicken is fully cooked through. The pasta should still have a slight bite—it'll finish cooking in the oven.

Once the pasta is cooked, remove the skillet from heat and stir in the 2 cans Campbell's Cream of Mushroom Soup, 0.5 cup milk, and 0.5 cup melted butter. The mixture will thicken slightly as it cools. Return the skillet to medium heat and stir in the 0.25 cup all-purpose flour and 3 cloves minced garlic cloves, cooking for 2-3 minutes until the sauce begins to thicken and the raw flour taste disappears.

Add the 2 cups shredded sharp cheddar cheese, 1 tablespoon dried parsley, 1 teaspoon salt, 0.5 teaspoon black pepper, and 0.5 teaspoon garlic powder. Stir constantly until the cheese is fully melted and the sauce is completely smooth and creamy. If the sauce is too thick, add 2-3 tablespoons of pasta water to reach your desired consistency—it should coat the back of a spoon but still be pourable.

Preheat your oven to 375°F. Transfer the entire mixture to a 9x13-inch baking dish (or similar size) and spread it evenly. The dish should be about ¾ full—this allows the top to brown beautifully while keeping the center creamy. Cover the dish tightly with aluminum foil and bake for 20 minutes. This steaming step ensures the pasta absorbs all the creamy goodness.

Remove the foil and bake for an additional 10-15 minutes until the top is golden brown and the edges are bubbling. The cheese should form a slightly crispy crust on top while maintaining a creamy texture underneath. If the top browns too quickly, tent it loosely with foil for the last few minutes to prevent over-browning.

Let the tetrazzini rest for 5-10 minutes before serving. This allows the flavors to meld together and the sauce to thicken slightly, creating that perfect creamy consistency. The dish should be hot and bubbly when you serve it—each bite should deliver tender chicken, al dente pasta, and a rich, velvety mushroom-cheese sauce.

Garnish with an extra sprinkle of dried parsley and serve immediately with crusty bread or a simple green salad. The one-pot magic means minimal cleanup and maximum flavor—this creamy masterpiece is perfect for feeding a crowd or meal prepping for the week ahead.

Health benefits of this dish

Protein-Packed Comfort

This creamy casserole delivers a solid 30-35 grams of protein per serving—thanks to the chicken and cheese—making it an excellent choice for muscle maintenance or post-workout recovery. The boneless chicken breast provides lean protein without the fat, while the sharp cheddar cheese adds all nine essential amino acids.

I always make extra portions because it's perfect for high-protein meal prep. 💪

Creamy Energy Boost

The combination of whole milk and butter in this recipe creates a rich source of healthy fats that provide sustained energy. These fats also help with nutrient absorption, ensuring your body gets the most from the vitamins in the Campbell's mushroom soup.

The cream of mushroom soup itself contains small amounts of B vitamins, which support metabolism and energy production.

Vitamin D & Calcium

Sharp cheddar cheese is a surprising source of vitamin D (about 10% of daily value per serving) and calcium (nearly 20% of daily value), both crucial for bone health.

The Campbell's mushroom soup also contributes calcium from its fortified ingredients. This makes Tetrazzini a great option for anyone looking to boost their dairy intake without drinking milk. 🧀

Fiber from Pasta

While this dish isn't typically fiber-rich, using whole wheat penne pasta instead of regular pasta adds about 5 grams of fiber per serving. Fiber supports digestion and helps keep you full longer.

For an even bigger boost, I sometimes stir in ½ cup frozen peas during the baking process—they blend right in and add color and nutrients without changing the texture. 🍝

Low-Carb Adaptation

For a lower-carb version, replace half the pasta with cauliflower rice (about 1 cup) mixed into the chicken before baking. This reduces carbs by roughly 30% per serving while keeping the creamy texture.

The cauliflower also adds a subtle sweetness that complements the mushrooms beautifully. This adaptation works surprisingly well for keto-friendly meals.

Meal-Prep Friendly

This dish reheats perfectly while maintaining its creamy texture, making it ideal for meal prep. The combination of protein, healthy fats, and complex carbs creates a balanced meal that keeps you satisfied for hours.

I always portion leftovers into airtight containers and store them in the fridge for up to 5 days—the flavors actually deepen overnight. 💡
