You know what happens when you go on vacation, even for a few days, and you have zucchini growing in your garden? Even when it’s only for four days and you’ve picked every visible zucchini you can right before you leave?

Bats, that’s what. Baseball bats.

Our Favorite Videos

Humongous baseball bat-sized zucchini that you can’t imagine could have grown in just four days. Let alone three of them.

What the heck? Where did these come from? Obviously you’re blind, you tell yourself, they must have been hiding under a leaf. Lots of leaves. Whatever.

Now you have them, so what to do? Zucchini bread and zucchini cake are obvious choices, and you can also scoop out some of the insides of these mongo zucchinis, stuff the zucchini shells, and bake them.

Which is exactly what we’ve done here.

Pesto Stuffed Zucchini

This stuffed zucchini recipe is somewhat of a gardener’s paradise. If you are growing zucchini, you are also likely growing tomatoes and basil.

We make pesto with our excess of basil, and we pick cherry tomatoes from our plants all summer long.

The stuffing for this recipe is just freshly made croutons and Mozzarella cheese, tossed with basil pesto, some grated Parmesan, a few chopped cherry tomatoes, and toasted pine nuts.

A perfect summer garden meal. Enjoy!

Pesto Stuffed Zucchini Recipe

  • Prep time: 10 minutes
  • Cook time: 1 hour
  • Yield: Serves 4


  • 2 cups of day old cubed bread*
  • 1 tablespoon butter
  • 2 tablespoons pine nuts
  • 1 very large zucchini (about 2 pounds), otherwise known as a baseball bat zucchini
  • 1/4 cup prepared basil pesto
  • 1/4 cup grated Parmesan cheese
  • 4 ounces fresh mozzarella, cut into cubes
  • A handful of cherry tomatoes, roughly chopped
  • Salt

*The bread should be a little dry, this way it will toast better. If you don't have day old or slightly dry bread, cut up fresh bread and lay out on a baking sheet. Heat in a 200°F oven for 10 minutes.


1 Toast croutons: In a medium skillet, melt butter on medium to medium high heat. Add the slightly dry cubed bread, toss to coat at least some of the sides in a little butter.

Lay out in a single layer cook, without moving the croutons, until one side is lightly browned, then toss and let cook a little more so a few more sides get a little brown. Remove from pan and let cool to touch.

2 Toast pine nuts: While the croutons are browning, heat a small skillet on high. Add the pine nuts and cook until they begin to brown (do not walk away, once they start browning they can easily go from brown to burnt!).

When they start to brown, remove them from the pan into a small bowl.

3 Combine croutons, Mozzarella, pesto, Parmesan, tomatoes, pine nuts: Place the croutons and Mozzarella in a medium bowl. Toss with the pesto. Add the grated Parmesan, chopped cherry tomatoes, toasted pine nuts, and toss some more.

4 Stuff the zucchini boats: Heat the oven to 375°F. Cut the zucchini in half lengthwise. Scoop out the inner flesh with a metal spoon, leaving 1/4 to a 1/2-inch thickness in the zucchini boats.**

5 Bake in oven: Place the zucchini boats in a roasting pan. Sprinkle the inside of the boats with salt. Fill the boats with the stuffing mixture.

Pour a cup or so of water into the bottom of the roasting pan (so that zucchini doesn't dry out on the outside), to about 1/4 inch depth.

Bake for 45 minutes at 375°F.

**In this recipe we are not using the zucchini flesh that we have scooped out. You can easily freeze it for later use with zucchini recipes such as zucchini bread, zucchini muffins, or zucchini cake. Or you can chop some of it up and mix it in with the stuffing mixture.

    I discovered a zucchini bat hiding in my garden. 4.5lbs! I doubled the recipe. On one half I also added ground hot Italian sausage crumbles to your recipe. The other half no sausage. I have to say that both sides were amazing!! This recipe is definitely a keeper. Thank you!

    Joining in from the countryside in France where I am awash in supersized courgettes. This is a lovely recipe, and it makes a fine lunch. I prettied it up with a grating of parmesan, and a few halved cherry tomatoes arranged insouciantly on top.

    Thanks to the person in the comments who pointed out zucchini relish. I have not only my own baseball bats, but my English neighbour’s cricket bats to deal with, as they asked me to cull their garden while they were elsewhere, and I turned my back on their zucchinis for a day too long!

    Can you believe it – I can’t find zucchini large enough for this recipe!!!! I just HAD to try it so I had to use slightly smaller zucchini but I was glad I decided to use about one cup of seasoned bread crumbs (homemade) instead of the croutons because I could really pack the filling in!

    We haven’t tired of zucchini yet this summer! This is a great use for overgrown ones, along with all the other vegetable in abundance this time of year. Our rule of thumb is to choose medium-sized zucchini and squash that feel heavy for their size. Their flavor is fully developed and their flesh is still tender.

    Just tried this tonight. Very easy and quick to prepare. I used smoked mozzerella and yellow cherry tomatoes (my 7yr old’s choice)and wheat bread. My husband loved it! I will definitely be making this again! Thanks for this recipe!
