Keto Shrimp Spaghetti Squash Ingredients
For the Shrimp
• Raw Peeled Shrimp – Choose raw shrimp for the best flavor and quick cooking, or substitute with cooked shrimp for a faster option.
• Salt – Essential for enhancing the shrimp’s natural flavors; adjust to taste.
• Black Pepper – Freshly cracked pepper adds a necessary kick to your shrimp.
For the Sauce
• Olive Oil – Great for sautéing; impart a rich flavor while keeping the dish healthy. Use avocado oil if you’re looking for something with a higher smoke point.
• Garlic – Use fresh cloves for the best aromatic effect, though garlic powder works in a pinch!
• Butter – Adds a creamy richness; can be replaced with ghee or a dairy-free alternative for lactose-free diets.
• Fresh Basil – Provides a fragrant touch; dried basil is a fine substitute in smaller amounts.
For the “Pasta”

Step‑by‑Step Instructions for Keto Shrimp Spaghetti Squash & Basil
Step 1: Prepare the Spaghetti Squash
Begin by preheating your oven to 400°F (200°C). Carefully cut the spaghetti squash in half lengthwise and scoop out the seeds. Place the squash halves cut-side down on a baking sheet lined with parchment paper. Roast in the oven for about 40 minutes, or until the flesh is tender and easily shredded with a fork, creating those delicious spaghetti-like strands.
Step 2: Sauté Garlic in Olive Oil
While the spaghetti squash is roasting, heat 2 tablespoons of olive oil in a large sauté pan over medium heat. Add 3-4 crushed garlic cloves and sauté for about 1 minute, or until fragrant, stirring continuously to prevent burning. This aromatic base is essential for the rich flavor of your Keto Shrimp Spaghetti Squash & Basil, so let those garlicky notes shine!
Step 3: Cook the Shrimp
Once the garlic is aromatic, carefully add 1 pound of raw peeled shrimp to the pan. Sauté the shrimp for approximately 5 minutes, occasionally stirring, until they turn pink and opaque. This visual cue indicates that they are perfectly cooked. Remove them from the pan and set aside, keeping that lovely garlic oil to infuse the next layers of flavor.
Step 4: Incorporate Fresh Basil
Next, add ½ cup of freshly minced basil into the sauté pan, stirring it into the garlic oil. Cook for an additional minute to allow the basil to release its aromatic oils and flavors, creating a fragrant backdrop for your dish. Return the cooked shrimp to the pan to bask in the herbaceous goodness; this will elevate your Keto Shrimp Spaghetti Squash & Basil to a new level.
Step 5: Combine with Spaghetti Squash
Once the spaghetti squash is ready, remove it from the oven and let it cool slightly. Using a fork, scrape the flesh to create spaghetti-like strands. Add the shredded spaghetti squash directly to the sauté pan along with 2 tablespoons of butter. Mix carefully to combine, letting the butter melt into the dish, and season with salt and black pepper to taste.
Step 6: Final Heating
Cook the mixture together for an additional 1-2 minutes, stirring to ensure everything is heated through and well combined. As you cook, the butter enriches the flavors while the basil and garlic mingle with the shrimp and spaghetti squash. Taste and adjust seasoning as desired, ensuring your Keto Shrimp Spaghetti Squash & Basil dish is bursting with flavor.
Step 7: Serve and Enjoy
Once everything is well combined and heated, remove the pan from the heat. Serve your delicious Keto Shrimp Spaghetti Squash & Basil warm on plates, optionally garnishing with extra fresh basil or a sprinkle of Parmesan cheese for added flavor. Dive into this quick and delightful meal, savoring each bite of this healthy alternative to traditional pasta!

Keto Shrimp Spaghetti Squash with Basil Recipe FAQs
How do I choose the best spaghetti squash?
When selecting spaghetti squash, look for ones that are firm to the touch and have a uniform color without any dark spots or blemishes. A good spaghetti squash should feel heavy for its size, indicating it’s full of moisture. Opt for smaller to medium-sized squashes, as they tend to be sweeter!
What’s the best way to store leftovers of this dish?
Store any leftovers in an airtight container in the fridge where they will keep well for up to 3 days. Make sure the dish has cooled down before sealing it, as this helps prevent moisture buildup which can lead to sogginess.
Can I freeze Keto Shrimp Spaghetti Squash with Basil?
Absolutely! To freeze, allow the dish to cool completely. Transfer it into a freezer-safe container or bag, keeping the shrimp and squash separate if possible. It can be frozen for up to 1 month. When ready to enjoy, thaw overnight in the fridge and reheat gently in a skillet over low heat for optimal texture.
What common issues should I be aware of when cooking shrimp?
One of the most common challenges is overcooking shrimp, which can render them rubbery. To avoid this, always cook shrimp until they are just pink and opaque, typically about 5 minutes. Keeping shrimp thawed and patted dry can also ensure even cooking and enhance flavor.
Are there any dietary considerations I should keep in mind?
If you’re cooking for someone with shellfish allergies, it’s best to avoid shrimp entirely. For a vegetarian alternative, consider using sautéed mushrooms or firm tofu instead. This dish is naturally gluten-free and can also cater to those on a keto-friendly diet as it has low-carb components!
What if I don’t have fresh basil on hand?
No worries! If fresh basil isn’t available, you can substitute it with dried basil; just use about one-third of the amount. As an alternative, consider using fresh parsley or oregano for a different flavor profile, although it will slightly change the overall taste of the dish.
