PIZZA NIGHT!  Two words that always bring a smile to my face!

Not only do my hubby and girls look forward to this night, but making a weekly dinner plan around this theme is soooo easy. I always know what we’re having that night.

My challenge is to come up with new and healthy pizza options that are crave-worthy and keep this sacred night interesting.

We enjoy Zucchini Noodle Crusted Pizza in the summer, Cauliflower Pizza Bites and Pizza Stuffed Mushrooms to keep things low-carb, a favorite pizza combination to inspire Hawaiian Pizza-Dillas and even enjoy Pumpkin Pizza.

Almost every time we incorporate seasonal produce in our Friday night ritual, we are rewarded with something special. And, butternut squash pizza is no exception. It’s a simple combination of butternut squash, caramelized onion and spinach with a cheesy mozzarella topping that makes it pop!

Butternut Squash Pizza Tips

To make this pizza pre-cook the flat bread crust for a few minutes, layer the ingredients on top of the crust and bake the pizza for a few minutes more. Follow these tips to prepare key ingredients the day before and this recipe comes together in a snap:

  1. Peel and dice the butternut squash in advance. You’ll be ready for this recipe or so many other delectable uses, such as Butternut Squash and Spinach Quesadillas. Squash will keep in the refrigerator for up to 5 days.
  2. Cut the cubes in small 1/2 inch sized pieces, preferably. The smaller the size, the quicker they will cook on the stove top.
  3. Roasted butternut squash is also an option. Use this if you are already making a recipe that calls for butternut squash, like Creamy Butternut Squash Soup.
  4. Make a big batch of Slow Cooker Caramelized Onions and freeze the bounty in small portions.
  5. Use flat bread to make this recipe quickly and keep the carbs down. However, any type of crust will work. This Homemade Whole Wheat Pizza Crust sounds fantastic!
  6. Make this recipe vegan by using dairy-free cheese and butter.
  7. Use gluten-free pizza crust, if desired.
