Ingredients Method

Ingredients

  

• 1 medium spaghetti squash (about 2.5–3 pounds)
• 2 tablespoons olive oil, divided
• 1 pound large shrimp, peeled and deveined (tails on or off)
• 1 tablespoon unsalted butter (optional, for finishing)
• 2 cloves garlic, minced
• Juice of 1/2 lemon, plus wedges for serving
• 2 tablespoons chopped fresh parsley (or cilantro)
• Salt and black pepper, to taste
• 2 teaspoons smoked paprika (or sweet paprika)
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1/2 to 1 teaspoon cayenne pepper (adjust to heat preference)
• 1 teaspoon dried thyme
• 1 teaspoon dried oregano
• 1/2 teaspoon kosher salt
• 1/2 teaspoon black pepper
• Grated Parmesan or Pecorino
• Cherry tomatoes, halved
• Red pepper flakes
• Extra virgin olive oil for drizzling

Method

 

1. Prep the oven and squash: Preheat your oven to 400°F (205°C). Carefully slice the spaghetti squash in half lengthwise. Scoop out seeds and strings. Brush the cut sides with 1 tablespoon olive oil and season with salt and pepper.
2. Roast until tender: Place squash halves cut-side down on a parchment-lined baking sheet. Roast for 35–45 minutes, depending on size, until a fork slides in easily but the strands still have a slight bite.
3. Mix the spices: In a small bowl, combine smoked paprika, garlic powder, onion powder, cayenne, thyme, oregano, salt, and black pepper. Taste a pinch and adjust cayenne if needed.
4. Season the shrimp: Pat the shrimp dry with paper towels. Toss with the spice mix and 1 teaspoon olive oil until evenly coated. Dry shrimp sear better and form a better crust.
5. Shred the squash: When the squash is done, let it cool for 5 minutes. Use a fork to gently pull the flesh into long strands. Transfer to a large bowl and set aside.
6. Heat the skillet: Warm a large cast-iron or heavy skillet over medium-high heat. Add 2 teaspoons olive oil. When the oil shimmers, it’s ready.
7. Blacken the shrimp: Add shrimp in a single layer without crowding. Cook 1.5–2 minutes per side until opaque with a deep, slightly charred crust. Work in batches if needed to avoid steaming.
8. Garlic and finish: Reduce heat to medium-low. Add butter (if using) and minced garlic to the skillet for 30 seconds until fragrant. Return any cooked shrimp to the pan and toss. Squeeze in lemon juice.
9. Combine: Add the squash strands to the skillet or toss everything in the bowl. Season with a pinch of salt, more pepper, and a drizzle of olive oil if it looks dry. Fold in parsley.
10. Serve: Plate the squash and shrimp. Finish with extra lemon, optional Parmesan, cherry tomatoes, or a sprinkle of red pepper flakes for heat.

Why This Recipe Works

Save

• High heat, big payoff: Blackening the shrimp in a hot skillet creates a flavorful crust that pairs perfectly with the delicate squash strands.
• Smart seasoning mix: A balanced blend of paprika, garlic, onion, cayenne, and herbs brings heat and depth without overpowering the shrimp.
• Roasted squash, not soggy: Roasting the spaghetti squash cut-side down pulls out excess moisture, so the “noodles” stay firm and slightly sweet.
• Fast protein, slow veg: Shrimp cook in minutes while the squash roasts, so everything comes together with minimal effort.
• Light but satisfying: Healthy fats, lean protein, and fiber keep you full and energized.

Storage Instructions

• Refrigerate: Store leftovers in an airtight container for up to 3 days. Keep shrimp and squash together for convenience or separate if you want to reheat differently.
• Reheat: Warm gently on the stovetop over low heat with a splash of water or broth, or microwave in 30-second bursts. Avoid overcooking the shrimp.
• Freeze: Not ideal.

  Shrimp can turn rubbery, and squash can get watery after thawing.

Health Benefits

• Lower-carb swap: Spaghetti squash offers the comfort of noodles with far fewer carbs and calories.
• Lean protein: Shrimp provide high-quality protein and essential minerals like selenium and iodine.
• Anti-inflammatory spices: Paprika, garlic, and herbs bring antioxidants and flavor without extra sugar.
• Good-for-you fats: Olive oil adds heart-healthy monounsaturated fats that help with nutrient absorption.
• Fiber and hydration: Squash is rich in fiber and water, supporting digestion and fullness.

What Not to Do

• Don’t skip drying the shrimp: Excess moisture prevents browning and leads to a limp, steamed texture.
• Don’t overcrowd the pan: Cook in batches if needed. Crowding kills the sear and the blackened crust.
• Don’t under-season: The squash is mild. You need bold seasoning on the shrimp and a final salt-and-lemon check.
• Don’t over-roast the squash: Mushy strands won’t hold up.

  Pull it when tender but still slightly firm.

• Don’t burn the garlic: Add it at the end over lower heat to avoid bitterness.

Alternatives

• Protein swaps: Try blackened chicken strips, scallops, salmon bites, or tofu. Adjust cook times accordingly.
• Spice level: Reduce cayenne or use sweet paprika only for a mild version. Add red pepper flakes or hot sauce for extra heat.
• Dairy-free: Skip the butter and finish with a splash of olive oil.

  Use nutritional yeast instead of Parmesan.

• Veggie boost: Toss in sautéed spinach, blistered cherry tomatoes, or roasted bell peppers for color and nutrients.
• Creamy twist: Stir in a spoonful of Greek yogurt or a splash of coconut milk off the heat for a light, creamy sauce.
• Citrus swap: Lime works well if you prefer a brighter, slightly tangier finish.

FAQ

How do I know when the spaghetti squash is done?

The skin should give slightly when pressed, and a fork should pull the flesh into strands with minimal resistance. Aim for tender but not mushy. If the strands look watery, it’s overcooked.

Can I use frozen shrimp?

Yes, but thaw completely in the fridge and pat very dry.

Excess moisture will prevent blackening and cause steaming.

What skillet works best for blackening?

A cast-iron skillet holds high heat and gives the best crust. A heavy stainless-steel skillet also works. Nonstick is fine in a pinch but won’t char as deeply.

Is the dish very spicy?

It’s moderately spicy with the listed cayenne.

For less heat, cut the cayenne in half or omit it. You can always add heat at the end with red pepper flakes.

Can I roast the squash ahead of time?

Absolutely. Roast, shred, and refrigerate for up to 3 days.

Reheat gently in a skillet with a little oil before adding the shrimp.

What if my squash is watery?

After shredding, place the strands in a colander and let them drain for a few minutes. You can also toss the strands in a hot, dry skillet for 1–2 minutes to evaporate excess moisture.

How can I make it more filling?

Add more vegetables, bump up the shrimp to 1.5 pounds, or sprinkle with nuts like toasted pine nuts. A light side salad with avocado also helps.

Can I make this on the grill?

Yes.

Grill the squash halves cut-side down until tender. Skewer the seasoned shrimp and grill 1–2 minutes per side. Toss together with lemon and herbs.

What wine pairs well with this?

A crisp Sauvignon Blanc or a dry rosé complements the spice and lemon.

For beer, try a pilsner or a light wheat beer.

How do I prevent the blackening spices from burning?

Use medium-high heat, not maximum. Make sure the pan is hot, the shrimp are dry, and cook quickly. If the pan smokes excessively, lower the heat slightly.

Final Thoughts

Blackened Shrimp Spaghetti Squash gives you bold, Cajun-inspired flavor with a light, fresh base.
