Easy Creamy Chicken Tetrazzini Casserole Recipe

How to Make Creamy Chicken Tetrazzini Casserole

Step 1: Cook the Pasta

Start by boiling your spaghetti or thin pasta in salted water until al dente. Drain and set aside, making sure not to overcook to keep the perfect bite in the casserole.

Step 2: Prepare the Sauce Base

In a large skillet, sauté finely chopped onion and garlic in a splash of olive oil until fragrant and translucent. Add sliced mushrooms and smoked turkey bacon, cooking until mushrooms soften and bacon crisps slightly.

Step 3: Build the Creamy Sauce

Sprinkle in flour or cornstarch while stirring continuously to form a roux. Gradually whisk in chicken broth and a splash of apple cider vinegar (natural) to create a smooth and bubbly sauce. Stir in plant-based cheese and the natural gelling agent until fully melted and blended.

Step 4: Combine Chicken and Pasta

Add shredded cooked chicken and the drained pasta into the skillet with the creamy sauce, ensuring everything is evenly coated and heated through.

Step 5: Bake the Casserole

Transfer the entire mixture into a greased baking dish. Sprinkle additional plant-based cheese on top for a golden crust. Bake in a preheated oven at 350°F (175°C) for 20-25 minutes until bubbly and lightly browned.

Pro Tips for Making Creamy Chicken Tetrazzini Casserole

Cook Pasta Perfectly: Always undercook by a minute, as it will continue to cook during baking to avoid mushiness.
Use Fresh Ingredients: Fresh mushrooms and quality smoked turkey bacon make a noticeable flavor difference.
Layer Flavors: Don’t rush the sautéing process; caramelizing onions and bacon enhances the depth of taste.
Check Consistency: Adjust the sauce thickness by slowly adding broth if it seems too thick before baking.
Rest Before Serving: Let the casserole stand for 5 minutes after baking to set the sauce and make serving easier.
