What Makes This Keto Mediterranean Squid Tomato Soup with Oregano So Good

Before diving into the how-to, it's worth understanding why this soup works so beautifully — especially for anyone eating keto.

The Keto-Friendly Breakdown

Spoiler alert: the total net carbs per bowl lands around 8–10g, making this completely compatible with a ketogenic lifestyle.

Squid — also called calamari — is genuinely underrated in home kitchens. It's affordable, widely available (fresh or frozen), and absorbs surrounding flavors like a sponge. The key is not overcooking it. Squid follows the rule of either cook it fast (under 2 minutes) or low and slow (20+ minutes). This soup uses the slow method, letting the squid become melt-in-your-mouth tender in the tomato broth.

Oregano ties everything together. Mediterranean oregano specifically has a more robust, slightly peppery flavor compared to Italian varieties. Do yourself a favor and use dried oregano here — it blooms beautifully in the hot oil and builds incredible depth.

How to Make Keto Mediterranean Squid Tomato Soup with Oregano Step by Step

This is where the magic happens. No fancy equipment, no culinary degree required.

Ingredients (Serves 4)

• 500g (about 1 lb) squid — cleaned, cut into rings (fresh or thawed frozen)
• 1 can (400g) crushed San Marzano tomatoes
• 3 tablespoons extra virgin olive oil
• 4 garlic cloves, thinly sliced
• 1 small onion, finely diced
• 1 teaspoon dried oregano (plus extra to finish)
• ½ teaspoon red pepper flakes (optional but encouraged)
• 500ml (2 cups) low-sodium fish or vegetable broth
• Salt and black pepper to taste
• Fresh parsley or fresh oregano to garnish

Step-by-Step Instructions

Step 1: Bloom the aromatics.
Heat olive oil in a large pot or Dutch oven over medium heat. Add the onion and cook for 3–4 minutes until softened. Add the garlic and dried oregano, stirring for about 60 seconds until fragrant. This step is everything — don't rush it.

Step 2: Build the tomato base.
Pour in the crushed tomatoes and broth. Add red pepper flakes if using. Stir well, bring to a gentle simmer, and let it cook uncovered for 10 minutes. Season with salt and pepper.

Step 3: Add the squid.
Slide the squid rings into the simmering broth. Reduce heat to low, cover partially, and cook for 20–25 minutes. Trust me on this one — the longer simmer is what transforms squid from rubbery to silky.

Step 4: Taste and finish.
Check seasoning. Drizzle with a little extra olive oil, sprinkle fresh oregano or parsley over the top, and serve immediately.

Pro Tips for Perfect Results

“Low and slow is the secret to squid that melts in your mouth — resist the urge to rush this one.”

• 🧊 Frozen squid is totally fine. Thaw overnight in the fridge and pat dry before cooking.
• 🍋 Add a squeeze of lemon at the end for a brightness boost.
• 🫙 Meal prep magic: This soup stores beautifully in the fridge for up to 3 days and the flavor actually deepens overnight.
• 🌶️ Adjust the heat level — skip the red pepper flakes for a milder version, or double them if heat is your love language.
