Blackened Tuna Steaks with Asparagus on Vegetable Mashed Potatoes
This is my favorite way to cook tuna. The tuna stays tender and has a wonderful spicy herb-and-smoke flavor.
Ingredients:
- 1 lb potatoes
- milk
- 1 red bell pepper
- 10 medium size mushrooms (brown or white)
- 1 small onion
- 2 cloves of garlic
- 1/2 cup chicken (or vegetable) stock
- 1/2 cup dry white wine
- 1 lb sashimi-grade tuna
- 12 green asparagus
- 2 tbsp butter
- 1tsp olive oil
- salt, pepper to taste
- Blackening spice: 5 tsp mild paprika
- Blackening spice: 1 tsp dried thyme
- Blackening spice: 1 tsp dried oregano
- Blackening spice: 1 tsp cayenne pepper
- Blackening spice: 1 tsp black pepper
- Blackening spice: 1/2 tsp garlic powder

Method:
- Combine the ingredients for the blackening spice.
- peel onion, cut into half rings
- core bell pepper, cut into strips

- wash asparagus, remove lower third of stems
- cut tuna steaks if necessary, coat with blackening spice
- peel potatoes, boil in water until soft (ca 20min)
- heat butter in heavy pan, add onions, cook on medium heat until golden brown (ca. 5-10min, add sliced bell pepper, cook another 5min, add garlic, cook 2min, add chicken broth and white wine, set on low heat, continue to simmer
- heat olive oil and 4tbsp water in heavy saucepan. Add 1 tsp of salt. Add asparagus, cover, cook for ca. 5-8min (to taste)
- heat stainless pan to very high heat, sear tuna steaks, 2min on top and bottom, 15-30sec per small side
- Mash potatoes, add vegetables, stir in milk until consistency is right, add salt to taste
- Spread potatoes on plate, put tuna on top, garnish with asparagus.
Notes:
- Preparation time: ca. 1h.
- Yields 2 servings
- Blackening the fish produces a lot of smoke. I strongly recommend to not attempt this without an exhaust fan. If you don't have one, you can place the fish on a grate, go outside and blacken/cook it with a soldering torch (the little kitchen torches won't work for that). Just sweep the flame over all sides of the fish until nice and blackened.
- In my experience,there is just no way to reasonably prepare mashed potatoes from less than 1 lb of potatoes. You will likely have leftover vegetable mashed potatoes.
- I'm normally using a pressure cooker to cook the potatoes.
