This hearty keto garlic squid recipe has been my dinner lifesaver during busy weeknights when I want something nutritious yet quick to prepare. The tender squid combined with zesty garlic and tomato creates a Mediterranean-inspired dish that feels gourmet but comes together effortlessly.
I first made this dish when searching for new seafood options that would fit my low-carb lifestyle. What started as an experiment quickly became a weekly staple that even my seafood-hesitant family members request regularly.
Ingredients
- Squid 10oz/300g: select fresh squid with clear eyes and firm texture for best results
- Lemon juice from half a lemon: adds brightness and helps tenderize the squid
- Olive oil 2 Tbsp: use extra virgin for richer flavor
- Garlic cloves 2: fresh cloves provide the best aromatic quality
- Pitted olives 1/3 cup: adds briny depth and healthy fats
- Arugula 1/2 cup: provides peppery freshness and visual appeal
- Tomato paste 2 Tbsp: concentrates umami flavor and creates a quick sauce
- Dry basil 1 Tbsp: infuses the dish with Mediterranean character
- Crushed pepper: adjust according to your heat preference
- Parmesan cheese: opt for freshly grated for maximum flavor impact
Step-by-Step Instructions
- Gentle Poaching:
- Cook the squid in a pan with a small amount of water for 3-4 minutes with the lid on. The steam helps cook the squid gently while retaining its tenderness. Be careful not to overcook as squid can quickly become rubbery. You'll know it's done when it turns opaque and slightly firm to the touch.
- Creating The Base:
- Drain any excess water from the pan and add lemon juice and olive oil to the cooked squid. This creates a flavorful foundation for the dish while the acidity from the lemon brightens the seafood flavor and the olive oil adds richness.
- Building Flavors:
- Incorporate the tomato paste into the squid mixture adding a splash of water if needed for consistency. Press the garlic cloves directly into the pan to release their full aromatic potential. Sprinkle in the dry basil and crushed pepper allowing the heat to activate their essential oils. Stir everything thoroughly to create a cohesive sauce that coats each piece of squid.
- Final Touches:
- Turn off the heat and fold in the fresh arugula and olives. The residual warmth will gently wilt the greens without making them soggy. The peppery arugula and briny olives create a perfect contrast to the tender squid.
- Serving:
- Finish by generously topping with freshly grated Parmesan cheese which adds a savory umami element that ties all the flavors together beautifully.

The secret to this recipe's success is truly in the quick cooking method. I learned through much trial and error that squid requires either very brief or very long cooking times. This quick method preserves the tenderness while infusing maximum flavor in minimal time.
Storage Tips
This keto garlic squid can be stored in an airtight container in the refrigerator for up to 2 days. The flavors actually develop beautifully overnight making it an excellent make-ahead option. When reheating be sure to do so gently over low heat to prevent the squid from becoming tough. Add a splash of water or broth if needed to restore moisture. I often make a double batch specifically to have leftovers for lunch the next day.
Serving Suggestions
This versatile dish works wonderfully on its own as a complete meal but also pairs beautifully with additional keto-friendly sides. Try serving it over cauliflower rice to soak up the delicious sauce or alongside a simple green salad dressed with olive oil and lemon. For a more substantial meal consider adding avocado slices or a handful of toasted pine nuts for extra texture and healthy fats. When entertaining I often serve this in small ramekins as an impressive appetizer that always generates compliments.
Mediterranean Heritage
This recipe draws inspiration from classic Mediterranean coastal cuisine where seafood is celebrated for its freshness and simplicity. Traditionally in regions like southern Italy and Greece squid is often prepared with minimal ingredients to showcase its delicate flavor. The combination of garlic olive oil and lemon has been used for centuries in these areas to enhance seafood dishes. What makes this version special is its adaptation to modern keto requirements without sacrificing the authentic Mediterranean flavor profile that has stood the test of time.
