“If you have fresh fish available, I would highly recommend whipping up a quick keto ceviche! I tried ceviche for the first time in Costa Rica and loved it so much. I ordered it every time we went out to eat just to compare which local restaurant made it the best. Well, they were all fabulous – and they all added their own little twists. We enjoyed this with my Keto Mixed Seed Crackers for a delicious, fresh summer lunch. I also stirred through diced Pickled Avocado (in place of regular avocado), and it adds a lovely flavour dimension. NOTE: If you prefer not to use limes, lemon juice will work equally well, but I love the classic combo of lime, coriander and chilli. Enjoy!” – Monya

More on Keto Ceviche…
Ceviche, a traditional Latin American dish, has gained popularity worldwide for its fresh flavours and vibrant ingredients. In recent years, the ketogenic diet has also become a prominent dietary choice for those seeking to improve their health and lose weight.

FOLLOW MONYA:
This ceviche retains all the essence of the classic recipe while adhering to the principles of the ketogenic diet. Instead of using starchy vegetables like corn or sweet potatoes, this version focuses on low-carb alternatives. Traditional ceviche typically includes diced raw fish or seafood, marinated in citrus juices and mixed with tomatoes, onions, and herbs. In my version, these ingredients are replaced with pickled avocado, which is low in carbs and high in great fats!
Not only is ceviche a delicious and nutritious dish, but it also showcases the versatility and adaptability of traditional recipes to cater to different dietary preferences. By embracing the principles of the ketogenic diet, making some innovative twists on can open up a world of culinary possibilities for those seeking to maintain a healthy lifestyle while enjoying the pleasures of flavourful cuisine.

It is important to note that to maintain ketosis, it’s essential to track carbohydrate intake and ensure it aligns with your daily macro goals. Consulting with a healthcare professional is advised before making significant dietary changes.

Ceviche
Per serving
Equipment
Ingredients
- 240 g (8.5 oz) fresh, skinless fish (I used cod)
- 2 limes, juice only
- 1/4 red onion, peeled and very finely chopped
- 1 small red chili, seeds removed and very finely chopped
- small handful coriander leaves, finely chopped
- 60 g (2.1 oz) Pickled Avocado, diced (Fats of Life recipe)
- sea salt flakes
- freshly ground black pepper
- 1 medium tomato, sliced
Instructions
- Remove the fish from it's packaging and pat dry with kitchen paper. Use a sharp knife to cut into small cubes. Place into a shallow bowl and squeeze over the fresh juice from 2 limes. Set aside for 20 minutes while you prep the remaining ingredients. Make sure that the fish is covered by the juice. A gentle stir every now and then helps.

- After 20 minutes, add the red onion and chilies. By this time you will notice that the fish is no longer translucent and raw-looking, but has turned white. This is due to the acidity in the lime juice that actually 'cooks' the fish. Leave for 10 minutes.

- To serve, stir through the chopped coriander and diced Pickled Avocado. Season with sea salt flakes and freshly ground black pepper. Drain excess juice (or use a slotted spoon to serve) and plate up with tomatoes (sliced or diced) to add a sweet element.
- Serve with Keto Mixed Seed crackers (not included in the macros). Enjoy!
