Tips

Tip 1

Use a mix of bell pepper colors for visual appeal and subtle flavor variations. Red peppers add sweetness while yellow brings mild citrus notes.

Tip 2

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

Good to Know

Refrigerate in airtight container for up to 4 days. Freezes well for up to 3 months; thaw overnight before reheating.

Make Ahead

Common Mistakes

Watch

Add spinach off-heat to avoid overcooking and preserve bright color and texture.

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.
