Step 1

Preheat oven to 350F.

Step 2

Slice zucchini in half, and carve them out with a spoon. Chop the zucchini 'meat' and set it aside. Line zucchini boats on a baking sheet lined with parchment paper or arrange in a baking dish.

Step 3

Heat olive oil in a non-stick skillet. Cook garlic for about 1 minute, then add zucchini meat. Cook for 1 to 2 minutes, then add mushrooms and cook for an additional minute. Add ground beef and cook until no longer pink. Drain as much liquid as possible. Season with salt and pepper.

Step 4

In a small bowl, combine tomato sauce with 1/2 cup chopped basil. Spread about 1/2 tablespoon sauce per boat. Stuff with meat mixture and top with shredded cheese.

Step 5

Bake for about 15-20 minutes or until cheese is melted and starts to be crispy. Remove from the oven and top with remaining basil. Serve immediately.
