How to Make Chicken Tetrazzini Casserole

Step 1: Prepare Ingredients

Start by cooking your spaghetti noodles according to package instructions until al dente. While the pasta cooks, chop the onions, mince garlic, slice mushrooms, and crisp up the smoked turkey bacon in a pan. Shred the cooked chicken breast into bite-sized pieces.

Step 2: Make the Creamy Sauce

In a large skillet, melt butter over medium heat. Whisk in flour to form a roux, cooking until lightly golden. Slowly add chicken broth while stirring, allowing the mixture to thicken. Stir in the vegetarian Worcestershire sauce (natural), apple cider vinegar, minced garlic, and a pinch of natural gelling agent to achieve the perfect creamy consistency.

Step 3: Combine and Bake

In a large mixing bowl, combine the cooked spaghetti, shredded chicken, sautéed mushrooms, fried turkey bacon, and the creamy sauce. Toss everything to coat evenly. Transfer the mixture to a greased baking dish and sprinkle the top generously with plant-based cheese. Bake at 350°F (175°C) for 25-30 minutes or until the cheese melts and the top turns golden brown.

Pro Tips for Making Chicken Tetrazzini Casserole

• Use day-old chicken: Leftover roasted chicken works perfectly and infuses more flavor.
• Don’t overcook pasta: Slightly undercook spaghetti for a better texture after baking.
• Enhance creaminess: Choose a high-quality plant-based cheese that melts well.
• Keep sauce loose enough: Ensure your sauce isn’t too thick before baking for moist casserole.
• Add fresh herbs: Sprinkle chopped parsley or thyme on top for freshness.
