Turkey Tetrazzini Ingredients
For the Pasta
• Spaghetti – This is the primary carbohydrate source, but feel free to use any pasta shape that your family enjoys.
For the Sauce
• Butter (unsalted) – Adds richness to the sauce; substitute with margarine or olive oil for a lighter option.
• Olive Oil – Enhances flavor and prevents butter from burning; vegetable oil can work well too.
• Onion (small, chopped) – Provides an aromatic base; you can omit this if you’re sensitive to onions.
• Garlic (cloves, minced) – Delivers intense flavor; garlic powder can be used as a substitute in a pinch.
• All-purpose Flour – Thickens the sauce; for a gluten-free option, use cornstarch instead.
• Cream Cheese (room temperature) – Adds creaminess to the sauce; sour cream makes a nice tangy alternative.
• Chicken Broth (low sodium) – Forms the flavor base for the sauce; vegetable broth can be used for a vegetarian twist.
• Milk – Balances the creaminess; you can also use dairy or plant-based milk depending on your preference.
• Italian Seasoning – Adds a delightful herbaceous flavor; a mix of dried oregano and basil can work as a substitute.
• Salt and Pepper – Essential seasonings to taste; adjust based on dietary needs.
For the Toppings
• Parmesan Cheese (grated) – Offers cheesy flavor and helps the top brown beautifully; mozzarella is a great substitute for a milder taste.
• Turkey (cooked and chopped) – This is the main protein; leftover turkey is ideal, but rotisserie chicken works just as well.
With these simple ingredients, you’ll be well on your way to whipping up a comforting Turkey Tetrazzini that’s sure to please!
