Watermelon Panzanella with Sourdough Croutons

This watermelon panzanella is a marriage between a poorly risen sourdough (a long story) turned into homemade sourdough croutons and a large watermelon that happened to be sitting on my countertop. And that happy union became a variation on a classic summer salad.

Traditional panzanella is an Italian bread salad made with tomatoes as the primary ingredient. In my version, sourdough croutons soak up summer flavors from the ripe and juicy watermelon.

Some notes and tips about this recipe

I find that it’s easiest to cut or pull off the crust with my hands and then slice the naked bread loaf into cubes.

It may take more or less time for your croutons to cook depending on the size of the cubes and how stale your bread is (i.e. stale bread = dry bread = less cook time).

The cucumber is seeded in order to reduce the liquid provided by the cucumber, since we want the bread to soak up as much watermelon as possible.

The easiest way to seed a cucumber is to slice it in half and then use a small spoon to scoop out the seeds.

We always save our jam jars to use for salad dressings, simple syrups, etc. The salad dressing recipe for this panzanella is my go-to dressing, sometimes adding a 1/2 tsp each of mustard and honey. Note that our family prefers a salad dressing that has a 2:1 ratio of olive oil:vinegar (or equivalent) rather than the classic 3:1 ratio, so feel free to add more olive oil to this recipe if vinegar-y is not to your taste.

FAQs about this watermelon panzanella with sourdough croutons

Could I use a different bread for the croutons?

Yes. Any rustic white bread would work well for this panzanella.

Can I substitute other herbs in this recipe?

Yes, you could sub the more classic chopped basil for the mint. Or use parsley if cilantro tastes like soap to you.

Is this vegan?

Yes, this recipe is for a vegan panzanella and vegan croutons.

What if I wanted to add cheese?

Go right ahead. I’d personally pick feta or a goat cheese.

What would you serve alongside this watermelon panzanella?

I served this with just a simple roasted sausage, and it would pair well with any simple roast or grill.

Can you freeze croutons?

Yes, croutons freeze well. I’d recommend tossing them back into the oven for a few minutes before starting to prepare this recipe.

What else can I do with homemade croutons?

You can, of course, use them on a salad. Or turn them into stuffing. Or a garnish for soup.

How long will the panzanella keep?

Bread salads are really best when served soon after tossing the croutons with the dressing and other vegetables. If they sit too long, the croutons will get soggy and sad. If you are bringing this panzanella to a BBQ or picnic, just keep the croutons separate until prior to serving.

Watermelon panzanella and assembly

  • While the croutons are in the oven, cut the watermelon, cucumber, red onion and tomatoes and add them to a serving bowl.
  • Combine all of the salad dressing ingredients (olive oil, vinegar, lemon juice, salt and pepper) in a small lidded jar.

  • Shake the salad dressing jar (make sure the lid is on well!) and pour it over the panzanella. Toss gently and let it sit at room temperature until ready to serve.


Our family likes a more vinegar-y salad dressing, so we use a 2:1 ratio rather than the classic 3:1 ratio. Please adjust the olive oil in the dressing to your tastes.
