Chicken (or Turkey after Thanksgiving) Tetrazzini is always a family favorite of ours. But since my daughter became vegetarian a few years ago, I had to learn ways to cook some of her favorite foods without the meat. Broccoli and Cauliflower Tetrazzini is every bit as comforting and delicious as Chicken Tetrazzini but can be enjoyed by vegetarians too.

There aren’t many people who can resist a creamy pasta dish with Parmesan cheese and a crunchy bread crumb topping. Even the meat lover in your family will be a fan of this meal.
Broccoli and cauliflower are two of my favorite vegetables.

Recipe Tips
I know there are many people who don’t like cauliflower and if that is the case, just use all broccoli. Or all cauliflower if you’re not a fan of broccoli. Carrots would also be really good in this dish.
Want to make it spicy? Add half a teaspoon of crushed red pepper flakes.

Type of Pasta To Use
I use fettuccine, but linguine or spaghetti work well too. You could even use farfalle, shells, or penne.
Storage
Leftovers will keep in an airtight container in the refrigerator for 4 days. Reheat in microwave.
