I don’t know you, but I would eat veggie-loaded pizzas every single day: , , , , ,. I love any sort of vegetarian pizza topping!

But have you ever try onions? If not, you must.

The humble budget-friendly onions shine on pizza. Their essential sweetness, bright color and amazing flavor turn the most simple pizza crust into something special.

Also, it’s worth noting that these economical root vegetables are also packed with great health benefits. Just saying.

For this pizza recipe, you don’t have to cook them on the stove, don’t bother, because the recipe makes them deliciously soft and ready for the oven by using a simple trick: the MARINADE.

All you have to do if finely slice the onions and toss them with some extra virgin olive oil, salt, pepper and let them rest for 30 minutes. It’s really a super simple marinade, nothing fancy, but I guaranteed it will make the onions softer, flavorful and more delicious.

For the pizza crust, I use my favorite that requires zero effort. But you can use your fav pizza dough if you wish. Ready for the recipe?

    Recipe notes

    Onion pizza ingredients

    Homemade pizza dough: this is a game changer! It’s a great 1-bowl recipe that uses instant yeast and makes a delicious crispy crust. Have a look at the video tutorial, it’s super easy!

    Onions: I love red onions, they’re sweeter than regular onions and they’re packed with flavonoids and antioxidants. But you’re welcome to use the onions you have.

    Marinade: extra virgin olive oil adds flavor, while the salt draws out the excess moisture from the onions making them soft, sweeter and ready for the oven.

    Mozzarella cheese: I use whole milk mozzarella in water, and if you use it keep in mind it’s important to not overload the pizza because its water content can make the crust soggy. Alternatively, shredded firm mozzarella works just fine.

    Olives: they add their savory flavor to the sweet onions. But they’re not key ingredients in the recipe, so you can skip them if you wish.

    Herbs: oregano adds aromatic notes and make the pizza more hearty, but also fresh thyme, fresh basil and chives are great with the onions.

    Salt & pepper: sprinkle some salt on the top and plenty of freshly ground black pepper.

    Note: the salt brings out the excess moisture form the onions. Don’t rush this step otherwise the onions will release their moisture once they’re in the oven. And you don’t want that when you bake your pizza.

    How to bake a crispy delicious pizza?

    • Don’t use a rolling pin! It pushes out those gas bubbles that make your crust lighter. Use your fingers to stretch the pizza dough;)
    • Place the rack in the lowest position close to the heating element to make the bottom golden and crispy. However, each oven is different, feel free to use the position that works best for your oven.
    • Preheat the oven and make sure it’s hot!
    • Bake your pizza on a hot  or . Alternatively, you can use a  (see my tips in the recipe card!). This avoid soggy bottom and makes the crust crispier.
    • Use and a or the back of a baking sheet to transfer your pizza to the hot stone. This helps if you use a sticky high-hydration dough like my

    Pizza dough

    • 1 ball easy pizza dough (or your fav dough)

    Onion topping

    • 2-3 (approx 250 grams) red onions (or any other color), finely sliced
    • 1 Tbsp extra virgin olive oil
    • ½ tsp fine salt
    • ⅛ tsp black pepper, plus more before baking
    • 6oz (170 grams) fresh mozzarella ball (or firm shredded mozzarella)
    • ¼ cup
    • ½ Tbsp dried oregano

    Pizza dough

    • Follow the through step 5, including shaping the pizza and preheating the oven.

    Instructions

    Onion topping

    • Marinate the onions: While the pizza dough is resting, slice the onion finely and place the in a bowl along with the olive oil, the salt and the pepper. Toss well to combine and let the onion mixture rest for about 30 minutes, don't rush this step.
    • Shape the dough: when the dough is ready follow step 5, place the dough on a parchment paper sheet and starting from the center, gently press it out with your fingers until you get approx a 9×13 inch pizza. Then gently place the dough onto a pizza peel or onto the back of a rimmed baking sheet.
    • Add the topping: top the dough evenly with mozzarella cheese, olives, and onions. Finish with freshly ground black pepper (a few cracks of the grinder are fine), dried oregano and a pinch of fine salt evenly distributed.
    • Bake the pizza: use the pizza peel to carefully transfer the pizza onto the preheated pizza stone. Bake the pizza until the cheese and crust are nicely browned, about 15 minutes. But each oven is different, keep an eye on it (e.g. in a forced fan oven it will take about 8-10 minutes).
    • Serve: allow the pizza to cool for a minute or two before. Slice and serve immediately. Serve with more freshly ground black pepper if you wish.
