How to make vegetarian stuffed zucchini
Ready to see how your stuffed squash comes together in just eight steps? Let’s see how it’s done!
Step 1: Preheat the oven to 375°F.
Step 2: With a spoon, scoop out the flesh of each zucchini half. Dice the zucchini flesh and set aside.
Step 3: Place the zucchini shells in a casserole dish.
Step 4: In a medium sauté pan, heat the oil over medium heat. Once hot, add the onion and pepper, then cook, stirring frequently, until softened, about 3-4 minutes.
Step 5: Add the mushroom, diced zucchini flesh, and Italian seasoning. Cook until most of the moisture is gone and the vegetables are soft, about 5-6 minutes.
Step 6: Stir in the rice.
Step 7: Divide the filling between the zucchini shells.
Step 8: Top each stuffed zucchini with Parmesan cheese, then bake for 25 minutes or until the zucchini shells have softened.
Your stuffed squash is ready to enjoy! I recommend serving right away while it’s hot out of the oven.
Variations for this dish
This recipe is very simple, which means there are lots of ways that you can customize it to suit your tastes. You’ll love how versatile it is!
As I mentioned earlier, for a vegan version, you can either omit the Parmesan or substitute vegan cheese. You’ll also want to make sure the brown rice is made in a vegan-friendly way.
On the other hand, if you want to add some meat, anything from shredded chicken to chorizo would be a delicious addition! Just make sure the meat is pre-cooked, then mix it into the filling before stuffing the zucchini shells.
Want to play around with other vegetables? You could throw in spinach, diced celery, or even some hotter peppers.
Looking for a low-carb dish? Substitute the brown rice with cauliflower rice, or omit the rice entirely and add more vegetables.
This zucchini dish is going to be best when it’s hot and fresh out of the oven. However, if you do have leftovers, they can be stored in an airtight container in the refrigerator for up to three days.
You can reheat in the microwave or in the oven at 350°F. Make sure they’re heated all the way through, then enjoy.
