Shrimp Scampi Zucchini Boats

These zucchini boats are basically summer’s way of saying “Hey, you can have your pasta and eat healthy too!”

Picture this: tender zucchini shells cradling succulent shrimp in a garlicky, buttery sauce that’ll make your kitchen smell like an Italian coastal restaurant.

The best part is watching people’s faces when they realize something this delicious is actually packed with vegetables and weighs in at under 100 calories per serving.

You get all the rich, wine-kissed flavors of classic shrimp scampi without the carb crash that usually follows.

Plus, these boats are basically edible bowls, which means less dishes to wash and more time to enjoy that second helping.

This recipe is proof that you don’t need to sacrifice flavor to eat lighter – sometimes the healthier option is actually the more delicious one.

Ingredients
For the zucchini boats
- 3 large zucchini (look for straight, firm ones for the best boat shape)
- 1 tablespoon unsalted butter, melted
- Salt and pepper to taste
For the shrimp scampi filling
- ¼ onion, diced (about ⅓ cup)
- 4-5 cloves garlic, minced
- ¼ cup dry white wine (like Sauvignon Blanc)
- 6-8 oz raw shrimp, peeled, de-veined, tails removed, and quartered
- ⅔ cup grape or cherry tomatoes, quartered
- 2 tablespoons fresh parsley, minced
- Cooking oil for sautéing
- Fresh lemon juice for finishing
- Salt and pepper to taste
Instructions
Prepare the zucchini boats
- 1 Preheat your oven to 400°F (200°C) and position the rack in the center for even cooking.
- 2 Trim the ends of the zucchini and cut each one in half lengthwise using a sharp chef’s knife. With a small spoon or paring knife, carefully make an outline around each zucchini half, leaving a ¼-inch thick border all around. Use a spoon or melon baller to scoop out the flesh to create hollow boats – save this scooped flesh and chop it roughly for the filling.
- 3 Brush about half of the melted butter onto the cut surfaces of the zucchini boats using a silicone brush. Season generously with salt and pepper, then arrange them cut-side up in a large baking dish. The boats should fit snugly but not overlap.
- 4 Roast the zucchini boats in the preheated oven for 15 minutes until they’re just starting to soften but still hold their shape well.
Make the scampi filling
- 5 While the zucchini roasts, add the remaining melted butter with a splash of cooking oil to a large skillet over medium heat. When the mixture is hot and shimmering, add the diced onion and the chopped zucchini flesh. Sauté until softened and lightly golden, about 3 minutes, stirring frequently to prevent sticking.
- 6 Add the minced garlic to the skillet and cook for just 30 seconds until fragrant – don’t let it brown or it will become bitter. Season lightly with salt and pepper.
- 7 Pour in the white wine, if using, and immediately turn the heat to high. Let the wine reduce completely, about 3-5 minutes, stirring often. You’ll know it’s ready when the pan looks almost dry and the alcohol smell has dissipated. Drain any excess liquid and let the mixture cool slightly.
Assemble and finish
- 8 In a large mixing bowl, combine the shrimp, quartered tomatoes, minced parsley, and the cooled vegetable mixture. Season with ½ teaspoon salt and ¼ teaspoon pepper, then stir gently to combine all ingredients evenly.
- 9 Remove the partially cooked zucchini boats from the oven and carefully spoon the shrimp mixture on top of each boat, dividing it evenly. Don’t worry about mounding it high – the shrimp will cook down slightly.
- 10 Return the filled boats to the oven and roast for an additional 10-15 minutes, or until the shrimp are pink and cooked through (they should reach an internal temperature of 145°F/63°C) and the zucchini feels tender when pierced with a fork.
- 11 Remove from oven and immediately finish with a generous squeeze of fresh lemon juice over each boat before serving hot.

Perfect Pairing Suggestions
Beverage Pairings
A crisp Sauvignon Blanc or Pinot Grigio echoes the wine used in cooking while complementing the seafood beautifully. For non-alcoholic options, try sparkling water with lemon or unsweetened iced tea with fresh mint. The bright, garlicky flavors also pair wonderfully with kombucha or a cucumber-infused water for a refreshing contrast.
Side Dish Recommendations
Serve alongside a mixed greens salad with lemon vinaigrette to add fresh crunch and more vegetables. Roasted asparagus or grilled broccolini complement the Mediterranean flavors while keeping the meal light. For heartier appetites, add cauliflower rice seasoned with herbs, or serve with crusty whole grain bread for non-low-carb diners.
Complete Meal Ideas
Start with bruschetta or caprese skewers as appetizers that match the Italian-inspired theme. For dessert, keep it light with fresh berries and a small portion of dark chocolate, or serve lemon sorbet to cleanse the palate. This creates a cohesive Mediterranean-style menu that feels special enough for entertaining.
Occasion Suggestions
Perfect for summer dinner parties when zucchini is at its peak, date nights when you want something impressive but not heavy, or meal prep since the boats reheat beautifully. These also make excellent brunch fare for a lighter alternative to heavy egg dishes.
Pro Tips and Troubleshooting
Professional Techniques
Salt your zucchini boats and let them sit for 10 minutes before brushing with butter – this draws out excess moisture for better texture. When sautéing garlic, keep it moving in the pan constantly; burnt garlic will make the entire dish bitter. For perfectly cooked shrimp, they should just turn pink and curl slightly – overcooking makes them rubbery and tough.
Storage and Make-Ahead
These boats store beautifully in the refrigerator for up to 3 days and actually taste even better the next day as flavors meld. To reheat, cover with foil and warm in a 350°F (175°C) oven for 10-12 minutes. You can prep the zucchini boats and filling separately up to 24 hours ahead, then assemble and bake when ready to serve.
Troubleshooting Guide
If your boats are getting too soft, reduce the initial roasting time to 12 minutes. Watery filling usually means the zucchini wasn’t drained well enough – always pat the scooped flesh dry with paper towels. For boats that tip over, slice a tiny bit off the bottom to create a flat surface, but be careful not to create holes.
Recipe Scaling
This recipe doubles easily for entertaining – just use two baking dishes and rotate their positions halfway through cooking for even results. When halving the recipe, use the same cooking times but watch carefully as smaller batches can cook faster.
Who knew eating your vegetables could feel this indulgent? These shrimp scampi zucchini boats prove that healthy doesn’t have to mean boring, and sometimes the best comfort food comes disguised as a nutrient-packed meal that happens to taste absolutely incredible.
