How to Make Ground Beef Zucchini Boats
Step 1: Prepare the Zucchini
Preheat the oven to 375°F (190°C).
Cut the zucchinis in half lengthwise and scoop out the center using a spoon to create boat-shaped shells.
Brush the zucchini halves lightly with olive oil and place them on a baking sheet.
Bake for 5–7 minutes to soften slightly.
Step 2: Cook the Beef Filling
Heat olive oil in a skillet over medium heat.
Add the diced onion and cook until soft and translucent. Stir in the garlic and cook for another 30 seconds.
Add the ground beef and cook until browned, breaking it apart with a spoon.
Drain any excess fat. Then stir in:
- Tomato sauce
- Italian seasoning
- Paprika
- Salt and pepper
Let the mixture simmer for about 5 minutes to develop flavor.
Step 3: Assemble the Zucchini Boats
Remove the zucchini from the oven and fill each one with the beef mixture.
Sprinkle shredded cheese evenly over the top.
Bake for 15 minutes, or until the cheese is melted and bubbly.
Step 4: Serve
Garnish with fresh herbs such as parsley or basil if desired.
Serve immediately and enjoy!
