As I’ve said before, probably more times than I should, I used to be vegetarian. And even though I’m no longer strictly vegetarian, I still make many dishes I used to eat way back then.

Both hubby and I adore this stuffed vegetable recipe. The taste of these zucchini boats is simply outstanding. The combination of onion, garlic, herbs, zucchini meat, and cheese makes for a flavorful dish that will impress your family or guests. Just wait and see.

Tips
  • You can easily convert this stuffed zucchini recipe from vegetarian to vegan, either by using vegan shredded cheddar or by omitting the cheese altogether. I have made this dish dairy-free and it’s just as tasty.
  • This recipe lends itself to tasty variations; for example, by substituting summer squash for the zucchini.
  • You can add or substitute a variety of vegetables, such as minced red bell pepper and/or corn kernels. But don’t add too many: simpler is better.
  • You can store these zucchini boats in an airtight container for up to a week in the refrigerator. I’ve never stored them in the freezer, but I expect they would freeze well.
  • I used dried herbs, but you can use chopped fresh herbs, if you have them.
  • You’ll need two knives: a chef’s knife or one that is big to cut the zucchini in half and then a smaller knife to cut into the flesh of the zucchini close to the edges of the vegetable.
  • Look at your zucchini and lay it on a table. Try to cut it in half so it lies flat and doesn’t rock like a seesaw.

How to make vegetarian stuffed zucchini

Pre-step

Get out a large skillet, a sharp knife, and a jelly roll pan or baking sheet.

Line the jelly roll pan with aluminum foil and set aside.

Step one

Gather the ingredients – olive oil, zucchini, onion, garlic, oregano, basil, smoked Gouda, parmesan cheese, salt, and pepper.

Step two

Take your large knife and cut the zucchini in half so the two halves lie flat.

Step three

Take a smaller knife, like a paring knife or something a little bit bigger, and cut at an angle down the side of the zucchini but leave around 1/8th inch between the zucchini flesh and the skin.

Step four

Take a kitchen teaspoon and scrape down the remaining flesh that remained in the zucchini. You want to leave a small layer of flesh in the zucchini shells, so don’t scrap too much out. (A)

Step five

Chop the zucchini flesh into smallish pieces. (B)

Step six

Peel and dice an onion. Heat the large skillet on medium heat and as it heats up, peel the garlic cloves and mince them.

Step seven

Once the pan heats up, add 1 – 2 tablespoons of olive oil, and once that comes to a shimmer, add the diced onion. Sauté for 7 minutes.

Step eight

Meanwhile, as the onion is cooking, cut the smoked Gouda into small cubes until it measures out to half a cup.

Step nine

Add the minced garlic and zucchini flesh and cook for 3 minutes. (C)

Step ten

Add the cubed Gouda cheese, parmesan cheese, herbs, salt, and ground pepper. (D)

Step eleven

Stand there and stir the cheese with the zucchini mixture until it melts. It takes about 3 minutes. (E)

Step twelve

Preheat the oven to 350 degrees Fahrenheit.

Step thirteen

Take a teaspoon, scoop the stuffing, and place it in the zucchini boats. Slice thin pieces of Gouda cheese and lay as many pieces as you like on top of the stuffing. (F)

Sprinkle a little dried basil and oregano on the cheese.

Bake for 30 – 35 minutes until the stuffing is bubbling and the cheese has melted to a nice golden brown.

Yum. Perfect. The zucchini has a slight crispiness to it and the stuffing is soft and delicious.

Time to serve it.

      1. Margie,

        Yay! I’m sure she’ll love it. It’s so good. I’ve tried it with a few different cheeses but I always go back to the gouda! Thanks for visiting my site 🙂 And commenting!

        xo,
        Elaine

        1. We Loved it! I used a packaged 4 cheese Italian mixture.I’m making it again for Thanksgiving if I don’t eat it all before. Have a happy Thanksgiving!♡♡

    3. The recipe is awesome. I can’t wait to try it, either. Happy to give this recipe a 5 star rating. BTWm enjoyed your hands. lol My grandma believed in looking at what she called the lifeline in hands. According to her interpretation, a hand like yours means you are going to live to be very old. She lived to be in her 90’s and died when she rolled off a new “feather tick” mattress by accident.

      1. Mary,

        Thanks so much! I hope you enjoy it when you make it!!

        That’s so interesting about your grandma and her looking at lifelines on hands. I admit that I look at peoples fingers when I meet them. I don’t find many hands that have my long pointer, but when I do, I feel like I’ve met a kindred spirit. 🙂

        Take care,
        And see you in twitterland!
        Elaine
