Recipe Ingredients
Stuffed Zucchini
Equipment
- 1 9×13 baking dish
- 1 large skillet
Ingredients
- 4 medium zucchini
- ½ teaspoon salt
- 1 pound ground beef
- 1 red bell pepper, seeds removed and chopped
- ½ cup chopped white onion
- 1 teaspoon minced garlic
- 2 cups marinara sauce
- ¼ cup chopped basil
- 2 teaspoons olive oil
- ½ cup grated Parmesan cheese
- ½ cup shredded mozzarella cheese
Instructions
- Preheat the oven to 400°F (200°C) and spray a 9×13 baking dish with cooking spray.
- Slice the zucchinis in half lengthwise. Scoop out the center seeds with a spoon to create a long well in each half. Arrange the hollowed zucchini halves in the greased pan.
- Sprinkle the zucchini with the salt and set them aside while you prepare the filling.
- In a large skillet over medium-high heat, add the ground beef and cook until no longer pink, about 8 minutes, breaking it into small crumbles as it cooks.
- Drain excess fat from the pan, then add the chopped bell pepper, chopped onion, and minced garlic. Cook about 4 minutes until the vegetables soften.
- Stir in the marinara sauce and chopped basil. Bring to a simmer and cook 2–3 minutes, stirring occasionally.
- Pat the zucchini boats dry with a paper towel to remove excess moisture, then brush them with olive oil.
- Spoon the beef and sauce mixture into each zucchini boat, packing them as full as possible.
- Bake the stuffed zucchini for 15 minutes. Remove from the oven, sprinkle each zucchini with Parmesan and mozzarella, and return to the oven for another 10 minutes, until the cheese is melted and lightly browned.
- Serve hot and enjoy as a complete meal.
Notes
- Store leftovers in an airtight container in the refrigerator for up to 3–4 days.
- Reheat in 30-second increments in the microwave or warm in the oven until heated through.
- Freezing is not recommended, as the texture of the zucchini and cheese changes after thawing.
Nutrition
Variations
- Use a meat-based pasta sauce to skip browning ground beef—just spoon the meat sauce into the zucchini boats.
- Swap ground beef for ground turkey, ground chicken, or Italian sausage for different flavor profiles.
- Try yellow summer squash instead of zucchini for a milder, sweeter result.
- For a vegetarian option, replace the beef with plant-based crumbles or seasoned black beans.
Tips + Tricks
- Use a pre-made meat sauce to save time—no need to cook ground beef separately.
- Swap proteins easily: turkey, chicken, or Italian sausage work well.
- Yellow summer squash is a tasty alternative to zucchini for a sweeter flavor.
- Plant-based crumbles or black beans make an easy vegetarian swap.
Quick Tip
Zucchini is abundant and easy to grow—if you haven’t tried growing it yet, consider adding a few plants to your garden for fresh summer produce.
Serving Suggestions
Serve the stuffed zucchini with a simple green salad or an Italian-style side like pasta salad or antipasto salad. Garlic bread is an excellent accompaniment if you want something to sop up extra sauce. Finish the meal with a light summer dessert, such as fresh berries or a fruit pie.
How to Store
- Store leftovers in an airtight container in the refrigerator for up to 3–4 days.
- Reheat in the microwave in 30-second increments or warm in the oven until heated through.
- Freezing is not recommended, as texture and cheese quality can suffer.
