How to Make Chicken Tetrazzini Casserole

Step 1: Prepare the Ingredients

Start by cooking the pasta according to package instructions until al dente. While the pasta cooks, chop the onions, garlic, and mushrooms. Cook the smoked turkey bacon until crisp, then chop it into bite-sized pieces. Shred the cooked chicken breasts and set all ingredients aside.

Step 2: Sauté the Aromatics and Mushrooms

In a large pan, sauté onions and garlic until fragrant and translucent. Add mushrooms and continue cooking until they release their moisture and become tender. This step develops the savory base of your sauce.

Step 3: Make the Creamy Sauce

Stir in the chicken broth, plant-based milk, apple cider vinegar (natural), and vegetarian Worcestershire sauce (natural) into the mushroom mixture. Sprinkle in your natural gelling agent and whisk carefully to prevent lumps. Let the sauce thicken gently over medium heat while stirring occasionally.

Step 4: Combine Chicken and Pasta

Add shredded chicken and cooked spaghetti into the sauce mix. Toss in the chopped smoked turkey bacon and plant-based cheese. Stir until everything is well coated and the cheese starts melting into the lovely creamy sauce.

Step 5: Assemble and Bake

Transfer the mixture into a greased casserole dish. Sprinkle a little extra plant-based cheese on top if desired. Bake in a preheated oven at 350°F (175°C) for 25 to 30 minutes, until the top is bubbly and golden.

Step 6: Garnish and Serve

Let the Chicken Tetrazzini Casserole cool slightly, then sprinkle fresh chopped parsley over the top for a bright, fresh finish before serving.

Pro Tips for Making Chicken Tetrazzini Casserole

• Don’t overcook the pasta: Cooking pasta al dente ensures it won’t get mushy during baking.
• Use freshly cooked chicken: Shredding warm chicken helps it integrate better with the sauce.
• Even sauce thickness: Whisk your natural gelling agent thoroughly to avoid clumps and ensure smooth sauce texture.
• Let casserole rest: Cooling for a few minutes before serving helps flavors settle and makes cutting easier.
• Customize the cheese amount: Adjust plant-based cheese quantities based on your preferred creaminess and cheesiness.

How to Serve Chicken Tetrazzini Casserole

Garnishes

A sprinkle of fresh parsley adds a burst of color and freshness that complements the creamy, cheesy goodness perfectly. You can also add a pinch of crushed smoked paprika for a subtle smoky aroma.

Side Dishes

Serve with a crisp green salad dressed lightly with lemon and olive oil to balance the creamy richness. Roasted vegetables like asparagus or green beans pair beautifully too, adding texture and freshness to your meal.

Creative Ways to Present

For a fun twist, serve the Chicken Tetrazzini Casserole in individual ramekins for personalized portions. You could also top the baked casserole with toasted sliced almonds or seasoned breadcrumbs for an appealing crunch.

Make Ahead and Storage

Storing Leftovers

Leftover Chicken Tetrazzini Casserole keeps well in an airtight container in the refrigerator for up to 3 days. Be sure to cool it fully before refrigerating to maintain flavor and texture.

Freezing

This casserole freezes beautifully. Place it in a freezer-safe container or wrap tightly with foil and freeze for up to 2 months. Thaw overnight in the fridge for best results before reheating.

Reheating

Reheat portions in the oven at 350°F (175°C) until warmed through, about 15-20 minutes. Using the oven helps maintain that lovely baked texture and melty cheese feel compared to microwaving.
