1-Getting started with this Chicken Tetrazzini Bake Creamy: Begin by preheating your oven to 350°F to ensure even baking. This creamy chicken tetrazzini recipe keeps things straightforward, so let’s dive into the process that leads to a dish full of tender pasta and rich flavors.

2-First, cook the chicken by placing 2 large chicken breasts in a large stockpot filled about three-quarters with water and adding 2 tablespoons chicken bouillon. Boil until the chicken reaches 165°F, which takes about 15 to 20 minutes, then remove and shred or dice it. This step not only flavors the chicken but also creates broth for later use.

3-Next, use the same pot of broth to cook 16 ounces of spaghetti until al dente, breaking it in half before boiling. Be sure to drain and reserve at least 1 and 1/2 cups of the broth for the sauce. For more ideas on pasta, check out our easy chicken spaghetti recipe that pairs well with this one.

4-Now, make the sauce by melting 2 to 3 tablespoons of unsalted butter in a skillet or Dutch oven. Sauté 1 diced medium onion with 1 teaspoon seasoning blend until translucent, about 5 to 7 minutes, then add 1 tablespoon minced garlic and cook for another minute. Pour in 1 cup heavy cream, stir in the processed cheese, and mix until melted, adding about 3/4 cup reserved chicken broth for creaminess.

5-Stir in 8 ounces sour cream, 10 ounces thawed and squeezed dry frozen spinach, and half of the 8 ounces shredded cheese. Add more broth as needed to reach a pourable consistency, usually around 1 and 1/2 cups total. For a deeper dive into chicken benefits, visit health benefits of chicken.

7-Bake covered with foil at 350°F for 20 minutes, then uncover and bake for another 20 to 25 minutes until bubbly and golden. Let it sit for 10 minutes before serving to thicken. Prep time is 20 minutes, cook time 45 minutes, for a total of about 1 hour and 5 minutes, making it a quick tetrazzini bake option.
