Preheat oven to 375°F. Line a large baking pan with foil or parchment paper.
Slice zucchini in half lengthwise. Use a spoon to scoop the flesh out of the insides of the zucchini. Give the zucchini a rough chop and set aside.
In a large skillet over medium high heat, cook sausage for about 3-4 minutes until it's browned.
Add chopped onion, minced garlic, and chopped zucchini to the skillet and cook until sausage is cooked all the way through and veggies are softened, about another 3-4 minutes.
Stir in marinara sauce.
Arrange zucchini boats onto the prepared baking pan and sprinkle with salt and pepper. Spoon sausage mixture into each and top with mozzarella cheese.
Bake until cheese is melted and sausage is a little bit bubbly, about 15-20 minutes. Use a fork to test that the zucchini is also tender, if you used a larger zucchini or if your boats are a little thicker, you may need to increase cook time.
Serve and enjoy, storing leftovers in the fridge.
- This recipe calls for 3 medium zucchini (6-8 inches/6-10 oz), but you can also use 4 or 5 small zucchini (5-6 inches/4-6 oz) or 2 larger zucchini (8-10 inches/10-14 oz). Smaller the zucchini will be more difficult to scoop out the centers, and larger zucchini will have more flesh and require a longer bake time. I do not recommend using extra-large zucchini (12+ inches/20+ oz).
- Use your favorite jarred marinara sauce or make your own. I have an easy marinara recipe here.
