Ingredients

Serves 2–3

• 1 small to medium sized spaghetti squash, roasted
• 1/2 cup Marinara Sauce
• 1/2 teaspoon Italian seasoning
• 1/2 teaspoon garlic powder
• 1/2 cup Mozzarella cheese, shredded (you may use low-fat if preferred)
• 1/4 cup parmesan cheese
• 2 tablespoons whole wheat Italian breadcrumbs
• 1 tablespoon olive oil
• Salt and pepper, to taste
• 6 large shrimp
• 2 tablespoons fresh parsley or basil, for serving (optional)

Equipment

• Baking sheet
• Sharp knife and cutting board
• Large spoon or fork
• Small bowl
• Oven-safe baking dish or the same baking sheet if large enough

Before you start

Preheat your oven to 400°F (200°C). If your spaghetti squash is not already roasted, you’ll want to roast it whole or halved first (see the step-by-step directions). That step gives you the tender strands that mimic spaghetti. Gather the rest of your ingredients so everything is within reach—shrimp cook quickly, so you’ll be assembling fast.

Step-by-step directions

1. Roast the spaghetti squash: Preheat the oven to 400°F (200°C) if you haven’t already. Carefully cut the spaghetti squash in half lengthwise. Scoop out the seeds with a spoon. Place the squash halves cut-side down on a baking sheet lined with parchment or foil. Roast for 30–45 minutes, until the flesh is tender and easily shredded with a fork. Cooking time depends on the size of the squash; a small to medium squash usually finishes closer to 30–35 minutes.
2. Shred the squash into strands: Remove the roasted squash from the oven and let it cool slightly so it’s safe to handle. Use a fork or spoon to scrape the flesh into spaghetti-like strands and transfer them to an oven-safe baking dish or leave them in the squash skins if you prefer a rustic presentation. Season lightly with salt and pepper.
3. Prep the shrimp: Pat the 6 large shrimp dry with paper towels. Season both sides with a pinch of salt and pepper and the 1/2 teaspoon garlic powder. Set aside briefly while you assemble other components.
4. Combine squash with marinara: Spoon the 1/2 cup marinara sauce over the shredded squash and sprinkle the 1/2 teaspoon Italian seasoning evenly on top. Toss gently with a fork to distribute the sauce and seasoning through the strands so every bite will be saucy.
5. Sear or roast the shrimp briefly: Warm the 1 tablespoon olive oil in a skillet over medium-high heat. Add the seasoned shrimp and cook 1–2 minutes per side, until they are pink and opaque. Alternatively, you can arrange shrimp on the baking sheet and roast at 400°F for about 6–8 minutes if you prefer less stovetop time. Remove shrimp from heat and set aside.
6. Assemble the topping: In a small bowl, combine the 1/2 cup shredded mozzarella, 1/4 cup parmesan cheese, and 2 tablespoons whole wheat Italian breadcrumbs. Stir so the cheeses and crumbs are evenly mixed. This mixture will create a melty, slightly crunchy finish.
7. Top the squash and add shrimp: Arrange the cooked shrimp evenly over the marinara-coated squash. Sprinkle the mozzarella-Parmesan-breadcrumb mixture across the top in an even layer.
8. Bake to melt and brown: Place the baking dish under the broiler for 2–4 minutes, watching closely, until the cheese is bubbly and the breadcrumbs are golden. If you prefer a gentler finish, bake at 375°F (190°C) for 8–10 minutes instead of broiling until the cheese has melted and the topping is lightly golden.
9. Finish and serve: Remove from the oven and let rest 2 minutes. Taste and adjust salt and pepper as needed. Sprinkle 2 tablespoons fresh parsley or basil over the top for a bright, fresh finish. Serve immediately.

Troubleshooting and tips

• If your spaghetti squash is large and thick, extend roasting time by 10–15 minutes so the strands are tender and not chewy.
• Pat shrimp dry before cooking to promote a quick sear and better texture. Overcooking will make shrimp rubbery—aim for just opaque and pink.
• Use a simple store-bought marinara or your favorite homemade sauce. If your sauce is very watery, simmer it briefly to thicken before adding to the squash.
• Want more crunch? Toast the whole wheat Italian breadcrumbs in 1 teaspoon olive oil until golden before mixing with the cheeses.
• To make this recipe lower in fat, choose low-fat mozzarella and use a light hand with the olive oil; the shrimp and marinara provide plenty of flavor.

Make-ahead and storage

Roast the spaghetti squash and store the strands in an airtight container in the refrigerator for up to 3 days. Cooked shrimp and the assembled, baked dish will keep in the fridge for 2 days. Reheat gently in a 350°F (175°C) oven until warmed through to preserve texture rather than microwaving, which can overcook the shrimp.

Variations

• Extra veggies: Stir in sautéed mushrooms, spinach, or diced bell pepper with the marinara for added color and nutrition.
• More heat: Add a pinch of red pepper flakes to the marinara or sprinkle over the finished dish for a little kick.
• Herb swap: Use either fresh parsley or fresh basil for the garnish—both play beautifully with the tomato and cheese.
• Double the shrimp: For a higher-protein meal, increase to 10–12 large shrimp and adjust pan space or roast them separately.

Nutritional notes

This version of Skinny Shrimp Parmesan Spaghetti Squash keeps calories and carbs in check by substituting traditional pasta with spaghetti squash. Shrimp supplies lean protein, while the modest amounts of mozzarella and Parmesan deliver satisfying melty cheese flavor without excess fat. Using whole wheat Italian breadcrumbs adds a little fiber and nuttiness.

Serving suggestions

• Pair with a crisp green salad dressed in lemon vinaigrette for a bright contrast.
• Serve with crusty bread for dipping in any extra marinara.
• Top with a squeeze of fresh lemon just before serving for a citrusy lift that complements the shrimp.

Final thoughts

This Skinny Shrimp Parmesan Spaghetti Squash is one of those dishes that feels special while still being simple enough for a busy night. Roasting the squash ahead saves time, and the quick-cooking shrimp comes together in minutes. The result is a balanced plate—creamy cheese, tangy marinara, and satisfying seafood—hinged around the surprisingly noodle-like texture of spaghetti squash. Give it a try when you want a cozy Italian-inspired dinner that’s a little lighter but still totally comforting.
