Ingredients

• 12 oz spaghetti
• 4 tbsp unsalted butter
• 4 tbsp all-purpose flour
• 4 cups chicken broth
• 1 cup whole milk
• 1 cup heavy cream
• 1.5 cups shredded Parmesan cheese
• 4 cups shredded cooked chicken
• 2 cups sliced mushrooms
• 1 cup frozen peas
• 2 cups shredded mozzarella cheese
• 1.5 tsp salt
• 1 tsp black pepper
• 0.5 cup bread crumbs (optional, for topping)
• 1 tbsp olive oil
• 0 cooking spray

Directions

Step 1

Cook spaghetti according to package directions until al dente. Drain and set aside.

Step 2

Preheat a large sauté pan over medium heat and add olive oil. Sauté the sliced mushrooms until soft and lightly browned, about 5 minutes. Remove from heat and set aside.

Step 3

In a large saucepan, melt butter over medium heat. Whisk in the flour and cook for 1 minute to create a roux.

Step 4

Gradually pour in chicken broth while whisking to prevent lumps. Stir in the milk and heavy cream. Bring to a gentle simmer and cook for 3-4 minutes, allowing the sauce to thicken.

Step 5

Stir in shredded Parmesan cheese, salt, and black pepper until smooth. Remove from heat.

Step 6

In a large mixing bowl, combine cooked spaghetti, shredded chicken, sautéed mushrooms, frozen peas, and the creamy sauce. Mix well until everything is evenly coated.

Step 7

Spray a large freezer-safe baking dish (or two smaller dishes if portioning) with cooking spray. Pour the tetrazzini mixture into the dish and spread evenly.

Step 8

Top with shredded mozzarella cheese. If desired, sprinkle bread crumbs over the top for added texture.

Step 9

If freezing, cover the dish tightly with foil and label with the date and cooking instructions. Freeze for up to 3 months.

Step 10

To bake immediately, preheat oven to 375°F (190°C). Bake uncovered for 25-30 minutes, or until hot and bubbly, with the cheese melted and golden.

Step 11

If baking from frozen, preheat oven to 375°F (190°C). Remove foil and bake for 45-50 minutes, or until fully heated through.
