Stuffed Zucchini
If you have a ton of zucchini in your garden you will want to make these!! I plant zucchini every year, some years I get nothing while others I have so much zucchini, I look for new ways to use them. You can fill zucchini boats with just about anything but I can’t get enough of these sausage stuffed zucchini! Some of my other favorite zucchini recipes are these Taco Stuffed Zucchini Boats and these delicious Turkey Santa Fe Zucchini Boats.


Ingredients
Here’s everything you will need to make this. See exact measurements in the recipe card below:
- Zucchini – the base of the dish. Yellow squash would also work.
- Tomato Sauce – I use my homemade marinara sauce, or use jarred for convenience.
- Olive oil
- Vegetables and Aromatics – red bell pepper, onions and garlic.
- Protein – I use Italian chicken sausage, removed from casing. Turkey or pork sausage would also work.
- Cheese – This gets topped with melted shredded mozzarella cheese and Parmesan
How To Make Stuffed Zucchini
See the video for step-by-step directions:
Variations
- Spicy Sausage and Ricotta: Combine spicy Italian sausage with ricotta cheese in place of mozzarella, chopped spinach in place of bell pepper, and finish with a touch of grated Parmesan cheese. Top with a sprinkle of red pepper flakes for extra heat.
- Vegetarian: Swap the sausage for a vegan sausage alternative.
- Zucchini: Sub yellow squash.
- Stuffed Zucchini Boats with Ground Beef: Substitute 90% or 93% lean ground beef and season with extra salt and Italian seasoning.
- Cheese: Swap parmesan with Pecorino Romano.
- Can’t eat cheese? Skip it or use a dairy-free cheese.
- Herbs: Add fresh herbs, like basil.
Serving Suggestions:
These are pretty filling, so I would go with a crisp, light garden salad on the side and some crusty bread or pasta if you want carbs.
- This easy Arugula Salad
- Romaine with Caesar Salad Dressing
- Mixed Baby Greens with Blue Cheese Dressing
- For some grains, try with quinoa, farro or orzo.
Storage
Store the leftover zucchini in the refrigerator for 4 days or in the freezer for 3 months. To reheat, thaw them in the fridge and reheat in the oven or microwave.
