Ingredients

- Lean ground beef: Opt for 85-90% lean beef to keep the dish flavorful but not too greasy. Browning the beef properly ensures a rich, savory base for the filling.
- Yellow onion and garlic: The onions and garlic add mild sweetness and aromatic depth. Dice finely, so they cook evenly with the beef.
- Marinara sauce: A good-quality store-bought or homemade marinara adds tang and richness. Choose one with simple ingredients.
- Worcestershire sauce: Adds a subtle umami and depth, enhancing the savory flavor of the beef mixture.
- Cheese: A blend of freshly grated Parmesan and shredded mozzarella creates a rich, creamy topping that melts well and adds a savory finish.

Variations
- Make it vegetarian: Swap the ground beef for lentils, crumbled tofu, or a plant-based meat alternative. These options still deliver a hearty texture and soak up the flavors of the sauce and spices well.
- Spice it up: Add red pepper flakes, chopped jalapenos, or a splash of hot sauce to the zucchini with ground beef for a zesty kick that pairs well with the cheesy topping.
- Cheesy twist: Swap the mozzarella with shredded pepper jack or smoked provolone for a new layer of flavor, or add a dollop of ricotta to each boat before baking.
- Tex-Mex Twist: Use cumin, chili powder, and paprika instead of Italian seasoning. Stir in diced tomatoes with green chilies, top with cheddar, and serve with sour cream and cilantro for a zesty kick.
How to Make Stuffed Zucchini with Ground Beef
Making ground beef stuffed zucchini is easier than you might think! Start by greasing a 9x13 baking dish so it's ready to go.
- Step 1: Prep the zucchini. Trim the ends, slice each zucchini in half lengthwise, and scoop out the flesh with a spoon to create little boats. Set them in the baking dish.
- Step 2: Brown the beef. Cook the ground beef and diced onions in olive oil over medium-high heat until fully browned. Drain off any excess grease. Reduce the heat and stir in the marinara, garlic, seasonings, Worcestershire sauce, and let it all simmer together for about 10 minutes.
- Step 3: Assemble. Spoon the beef mixture into the zucchini boats.
- Step 4: Add cheese and bake. Top with the shredded cheese blend. Bake at 400°F for 25 minutes, until the zucchini is tender and the cheese is melted and bubbly.
Hint: Salt to reduce moisture.
Sprinkle the scooped zucchini with a bit of salt and let sit for 10 minutes, then blot dry to avoid watery boats.
Expert Tips
- Use medium-sized zucchini for even cooking: Smaller zucchini may not hold enough filling, while overly large ones can take longer to soften. Look for zucchini that's firm and about 6-8 inches long.
- Use the right tool for scooping: A small spoon or melon baller makes it easier to hollow out the zucchini without breaking the shells.
- Simmer the filling for flavor: Letting the beef mixture simmer gives the sauce time to thicken and develop a rich, balanced flavor that won't make the zucchini soggy.
- Broil for a crispier top: Broil for 2-3 minutes in the end for bubbly, golden cheese, just watch closely to avoid burning.
- Let them rest before serving: Allowing the baked zucchini boats to sit for 5 minutes before serving helps the filling set and makes them easier to plate.
Serving Suggestions
These ground beef and zucchini boats are versatile enough for a casual family dinner or a crowd-pleasing potluck; just pair them with your favorite sides to round out the meal.
- Make them for an easy weeknight dinner paired with sheet pan breadsticks and twice-baked potatoes for a satisfying meal.
- Serve at your next potluck with bruschetta pasta salad, creamy potato salad, and strawberry fluff salad.
Storing Leftovers
- Storing: Leftover squash boats with ground beef can be stored in an airtight container in the refrigerator for up to 3 days. Due to the high water content in zucchini, freezing is not recommended, as the zucchini can become mushy when reheated.
- Reheating: Warm leftovers in the microwave in 30-60 second intervals until heated through, or reheat in the oven at 350°F for about 10-15 minutes.
