Tips for the Best Chicken Tetrazzini
Elevate your casserole with these simple tips and variations:
Make It Extra Cheesy
- Add Cream Cheese: Incorporate 8 ounces of full-fat cream cheese into the sauce for added richness and tang.
Enhance the Chicken Flavor
- Pan-Fry the Chicken: Before adding to the casserole, cook the shredded chicken in the skillet with a bit of butter and garlic. Deglaze with white wine to capture those flavorful brown bits.
Customize the Vegetables
- Vegetable Options: If you’re not a fan of mushrooms, substitute with broccoli florets, spinach, or green beans to add color and nutrients.
Swap the Protein
- Different Meats: Use leftover turkey or ham instead of chicken for a new twist on the classic dish.
Go Vegetarian
- Vegetarian Option: Omit the chicken and use vegetable broth. Add more vegetables like bell peppers, zucchini, or artichokes for a hearty vegetarian version.
Make Ahead and Storage
Plan ahead with these storage tips:
