Ingredients You’ll Need

The ingredients for this Creamy Turkey Tetrazzini Casserole Recipe come together in harmony. Each one plays its part in building a casserole that’s flavorful without being fussy. Plus, you probably have most of these pantry staples on hand already!

• Spaghetti: Cook it al dente to keep a nice bite after baking and avoid mushy noodles.
• Green Pepper: Adds a subtle crunch and a hint of freshness—feel free to sauté it first if you want it softer.
• Turkey: Leftover cooked turkey works beautifully here; shredded or chopped, either is great.
• Cream of Mushroom Soup: Provides earthiness and creaminess that forms the base of the sauce.
• Cream of Chicken Soup: Adds extra depth and richness to the creamy sauce.
• Sour Cream: Gives the sauce a slight tang that balances out the heaviness of the cheese and soups.
• Milk: Helps loosen the sauce to a perfect creamy consistency.

• Spicy Kick: Adding a pinch of red pepper flakes or some diced jalapeños gave it a nice warming heat that my family adored.

• Different Proteins: If you don’t have turkey, cooked chicken or even tuna can be swapped in to keep the creamy vibes going.

How to Make Creamy Turkey Tetrazzini Casserole Recipe

Step 1: Preheat and Prepare Your Ingredients

Start by heating your oven to 350°F (175°C). This gives your oven plenty of time to get evenly hot while you mix your ingredients. Cook the spaghetti according to package instructions—try to avoid overcooking since it will bake some more later. Drain and set aside.

Step 2: Build the Creamy Turkey Mixture

In a large mixing bowl, combine both cans of cream soups, sour cream, and milk. Mix until smooth, then stir in the chopped green pepper and cooked turkey. I found that folding gently keeps the turkey nice and chunky without breaking it down too much. This mix is where all the creamy magic happens, so make sure everything is well incorporated.

Step 3: Toss in the Spaghetti and Transfer to Casserole Dish

Add the cooked spaghetti to the bowl and stir it into the creamy turkey mixture until the noodles are evenly coated. This step ensures every bite is filled with flavor. Pour everything into a 13×9-inch baking dish and spread it out evenly. Then sprinkle the grated sharp cheddar cheese generously on top for a perfect golden crust.

Step 4: Bake and Enjoy!

Cover the casserole tightly with foil to keep all the moisture locked in. Bake in the preheated oven for about 30 minutes, or until the cheese is melted, bubbling, and lightly browned around the edges. When I first tried uncovering it too soon, the top dried out, so keeping that foil on until the end has been a game changer for a creamy finish.

How to Serve Creamy Turkey Tetrazzini Casserole Recipe

Garnishes

I like to sprinkle freshly chopped parsley or a pinch of grated Parmesan on top right before serving—it adds a fresh pop of color and a hint of brightness that cuts through all that rich creaminess.

Side Dishes

For sides, crisp green salads or steamed green beans work perfectly to balance the richness of the casserole. On occasion, I’ll whip up some garlic bread to scoop up every saucy bite—trust me, it’s the ultimate comfort combo.

Creative Ways to Present

For holiday gatherings, I’ve served this in individual ramekins topped with a sprinkle of toasted bread crumbs for added crunch and a little festive flair. It’s a great way to elevate it for guests without extra fuss.

Make Ahead and Storage

Storing Leftovers

After dinner, I like to let the casserole cool completely before covering it tightly with plastic wrap or transferring leftovers to airtight containers. Stored in the fridge, it keeps well for 3 to 4 days and reheats beautifully.

Freezing

I often freeze leftovers in portion-sized containers for easy future meals. Just make sure to thaw overnight in the fridge before reheating to keep the creamy texture intact and prevent separation.

Reheating

To reheat, I cover the casserole with foil and warm it in a 350°F oven until heated through, usually about 20 minutes. This method keeps the cheese melty and prevents drying out, unlike microwaving which can make it a bit rubbery.
