How to Make Homemade Flatbread Pizza 

Mushrooms are one of my favorite foods ever. If I could eat only five foods for the next month, mushrooms would be one of them. In fact, I love them so much that I once visited Italy during mushroom season so I could get my fill of fresh ones! 

So it felt pretty right to combine my loves of mushroom and pizza–all things Italian, right?!–to make the ultimate tasty wild mushroom pizza. This one is pretty easy to make, since you don’t even need pizza sauce or fresh basil.

I ended up creating a fairly low-calorie pizza loaded with veggies. For the crust of this flatbread pizza, I used a flatbread pizza crust that’s also fairly low in calories.

This Wild Mushroom Pizza is So Easy to Make

How to make this homemade pizza? The first step is prepping the sauteed mushrooms and onions. To do this, I started preparing the toppings by sautéing mushrooms in low-sodium vegetable broth in a large skillet over medium heat. You can also cook the mushrooms in a nonstick pan.

The key is to stir the mushrooms and cook until the liquid begins to thicken. Then you continue to cook, stirring, until it becomes pretty thick and that’s when you take the veggies off the burner. This adds additional flavor for very few calories.

Then I caramelized onions and garlic. Many people think you need lots of oil and sugar to accomplish this, but you actually don’t need either! It helps to slice the onions into thin slices. If you don’t have white or yellow onions, on hand, you can use red onions.

I next cooked up some kale for a touch of green, as well as extra nutrition and filling fiber. I love a cheesy pizza, so I topped the crusts with a part-skim mozzarella, goat cheese, and Parmesan. I added the cooked onions and mushrooms, plus a sprinkle of red pepper flakes for a hint of spice.

Then my pizzas were ready to pop into the oven on a baking sheet! As for nutritional information? You end up with pizzas that are high in protein, offering 11 grams–22%of the daily value–per serving to help keep you fuller for longer. Plus, who can say no to a golden brown crust?

This recipe makes four servings, so it’s great for family pizza night. Or if you’re like me, you can make it for lunch and store the leftovers in the fridge. I suggest serving a couple of slices with a side salad or some steamed or sautéed veggies to add even more greens to your meal.

If you’re wanting a side dish to go along with this homemade flatbread pizza, opt for a side salad portion of a chopped salad or a Mediterranean vegetable salad.
