Ingredients You’ll Need

The ingredients in this Creamy Turkey Tetrazzini Casserole Recipe combine basics that deliver big flavor without fuss—think creamy soups meeting tender turkey and melty cheese all wrapped around spaghetti noodles. When shopping, look for good quality cream soups and sharp cheddar to keep things tasty and simple.

• Spaghetti: Cook just until al dente to avoid mushy noodles in your casserole.
• Green Pepper: Adds a nice crunch and fresh pop of color—you can substitute with bell pepper if you like it sweeter.
• Turkey: Leftover roasted or shredded turkey works perfectly for this recipe.
• Cream of Mushroom Soup: Gives that comforting, savory creaminess that’s essential for the sauce.
• Cream of Chicken Soup: Pairs super well with the mushroom soup adding richness and depth.
• Sour Cream: Brings tang and enhances creaminess without overpowering the flavors.
• Milk: Thins out the sauce to the perfect consistency—whole milk is best, but 2% works too.
• Sharp Cheddar Cheese: Use freshly grated for meltier, more flavorful topping.

Variations

I’ve played around a bit with this Creamy Turkey Tetrazzini Casserole Recipe over the years, and it’s fun to customize! Don’t hesitate to switch up veggies or add some herbs to suit your mood or what’s in your fridge.

• Vegetable Twist: I like adding mushrooms or frozen peas in addition to green peppers—they boost flavor and nutrition effortlessly.
• Dairy-Free: Swap cream soups and sour cream with dairy-free alternatives if you’re avoiding lactose, and choose your favorite dairy-free cheese.
• Spicy Kick: For a little heat, sprinkle in some crushed red pepper flakes or add diced jalapeño peppers when mixing.
• Herbs & Seasonings: Fresh parsley or thyme stirred in at the end brightens things up beautifully.

How to Make Creamy Turkey Tetrazzini Casserole Recipe

Step 1: Prep Your Ingredients and Cook Spaghetti

Start by cooking your spaghetti according to package instructions until it’s just al dente — I usually drain and rinse it briefly with cool water to stop the cooking and prevent sticking. While the pasta is doing its thing, chop your green pepper and shred or chop the turkey into bite-size pieces so everything mixes evenly in the casserole later on.

Step 2: Make the Creamy Turkey Mixture

In a large mixing bowl, combine the can of cream of mushroom soup, cream of chicken soup, sour cream, and milk. Stir until smooth and creamy—that’s your delicious sauce base. Then add the chopped green pepper and turkey, folding everything gently together so the turkey is nicely coated but still chunky and tender.

Step 3: Combine Spaghetti and Sauce

Once your creamy turkey mixture is ready, fold in the cooked spaghetti noodles until they’re fully coated with that luscious sauce. Make sure you don’t overmix or the noodles might break apart too much, but you want that creaminess to reach every bite.

Step 4: Bake and Top with Cheese

Transfer everything into a greased 13×9-inch baking dish, then sprinkle the grated sharp cheddar cheese evenly across the top. Cover tightly with foil to keep it moist as it bakes. Bake at 350°F for about 30 minutes or until the cheese is melted, bubbly, and starting to turn golden around the edges. If you want a more browned top, uncover in the last 5 minutes and watch carefully.

How to Serve Creamy Turkey Tetrazzini Casserole Recipe

Garnishes

I love topping this casserole with a sprinkle of fresh parsley or chives—it adds a fresh, vibrant pop that complements the creamy richness perfectly. A little cracked black pepper on top right before serving also helps brighten the flavors.

Side Dishes

To round out the meal, I usually serve this with a crisp green salad tossed in a tangy vinaigrette and some roasted or steamed veggies like broccoli or green beans. A light side balances the richness wonderfully.

Creative Ways to Present

For special occasions, I’ve baked this in individual ramekins to make personalized servings that feel a bit fancy. It’s also fun to sprinkle toasted breadcrumbs over the cheese for a crunchy topping twist that everyone enjoys.

Make Ahead and Storage

Storing Leftovers

I store leftovers tightly covered in the fridge and find the casserole stays creamy and moist for up to 3 days. It’s a lifesaver for quick lunches or dinner next day with zero extra effort.

Freezing

This casserole freezes really well—just cover tightly with foil then plastic wrap before freezing. To enjoy later, thaw overnight in the fridge and then reheat in the oven to retain that cozy texture.

Reheating

I prefer reheating in the oven at 350°F covered with foil to avoid drying out. Microwaving works for a quick fix but tends to make it a bit watery, so I recommend adding a few extra minutes if reheating from frozen to warm evenly.
