Tips

Tip 2

Don't skip the fresh basil finish; it brightens the soup and reinforces the pizza flavor profile without additional cooking.

FAQ

Can I make this vegan?

Yes. Omit the Parmesan topping or substitute nutritional yeast. All other ingredients are plant-based. Use vegetable broth and pizza sauce without anchovies.

What if I don't have pizza sauce on hand?

Mix 1 cup marinara sauce with 1 teaspoon Italian seasoning and a pinch of garlic powder to approximate pizza flavor. Or use tomato sauce plus extra oregano and basil.

How long can I keep leftovers?

Refrigerate for up to 4 days in a sealed container. Freeze for up to 3 months; reheat gently on stovetop, adding a splash of broth if soup thickens.
