If you’re a sushi aficionado looking to explore beyond the conventional, or perhaps you’re on a low-carb journey seeking to satisfy those sushi cravings, you’ve landed in the right place. Today, we’re transforming the beloved spicy tuna roll into an innovative, guilt-free delight: Spicy Tuna on Crispy Cauliflower Cakes. This recipe is not only a healthier take on a classic favorite but also a celebration of vibrant flavors and exciting textures.
Ingredients You’ll Need:
- Sashimi-grade tuna (finely chopped)
- Avocado
- Green onions
- Frozen riced cauliflower
- Rice vinegar
- Salt and pepper
- An egg
- Olive oil
- Spicy mayo
- Jalapeño
- Toasted sesame seeds
From Market Fresh to Kitchen Ready:
This culinary adventure begins with finely chopping sashimi-grade tuna. If you’re in for a flavorful shortcut, grab some pre-seasoned poke—like I did from my local Farmer’s Market—that already has a burst of seasonings and spring onions. Then, you’ll also want to finely chop some avocado and green onions for a creamy texture and a punch of sharpness, respectively.
Mastering the Cauliflower Cakes:
The foundation of this dish is the cauliflower cakes, an excellent stand-in for the rice typically found in sushi. If you’re using frozen riced cauliflower, as I did, you’ll want to toast it in a skillet first. This step is crucial for removing all the water, ensuring the cauliflower gets a bit golden brown, just the way we want it.
Season your cauliflower rice with some rice vinegar, salt, and pepper to taste before adding an egg and mixing it thoroughly. The egg acts as a binder, helping your cauliflower mixture achieve the perfect consistency for forming into cakes.
Here’s where it gets fun: I prefer cooking my cauliflower cakes in a waffle iron for perfect crispiness with minimal fuss. However, if you don’t have a waffle iron, there’s no need to worry. You can easily form little patties and fry them up in a pan with some olive oil. The goal is golden brown and crispy cakes that’ll hold up against the juicy, spicy tuna topping.
The Grand Assembly:
Once your cauliflower cakes are ready, cut them into quarters and start topping them with your avocado and spicy tuna mixture. The creamy avocado provides a rich contrast to the zing of the tuna, creating a symphony of flavors in your mouth.
But we’re not stopping there. Sprinkle some spring onions for an extra layer of flavor, a drizzle of spicy mayo for that creamy heat, and a few slices of jalapeño for an additional kick. And because we eat with our eyes first, finish off with a sprinkle of toasted sesame seeds for a touch of nuttiness and a restaurant-worthy presentation.
