Preparation Time: 20 minutes
Cooking Time: 35 minutes
Servings: 6
Ingredients:
- 1 lb. Fresh tuna steaks (1-inch thick)
- ½ loaf of day-old breadcrumbs
- 1 lb. Extra-wide egg noodles, cooked to al dente
- 4 tbsp. Grass-fed butter, divided
- 2 tbsp. All-purpose flour
- 1 cup White wine
- 1 cup Water
- 1 tsp. Peppercorns
- 1 Bay leaf
- 1 tbsp. Extra-virgin olive oil
- 16 Small button mushrooms, thinly sliced
- 2 Large shallots, chopped
- 1 ½ cups Chicken stock
- ½ cup Heavy cream
- 1 cup Frozen peas
- 1 ½ tsp. Ground thyme
- Crushed Himalayan pink salt and cracked black pepper to taste
- Chopped fresh parsley leaves for garnish
Instructions:
- Begin by preheating the oven to 250°F and toasting the bread until it achieves a golden, crispy texture. Set it aside.
- In a skillet over medium-high heat, combine white wine and water. Allow the mixture to simmer until it reduces by half. Add peppercorns and a bay leaf. Lower the heat and gently poach fresh tuna steaks in the liquid for about 12 minutes until they become tender. Once done, set the tuna aside.
- In another skillet over high heat, add extra-virgin olive oil and half of the butter. Toss in sliced mushrooms and chopped shallots, sautéing them for approximately 3 minutes until they become soft and fragrant. Season with a pinch of salt and pepper. Add all-purpose flour and ground thyme, then whisk in chicken stock and heavy cream. Stir continuously for about 1 minute and incorporate frozen peas.
- Transfer poached fresh tuna steaks to a plate and gently flake them apart using a fork. Add cooked extra-wide egg noodles to a large casserole dish. Combine the flaked tuna, sautéed mushroom mixture, and other ingredients in the dish. Crumble the toasted breadcrumbs over the top and season the casserole with salt and pepper to taste.
- Place the casserole dish in the oven and bake for a short while, just until everything is heated through. Serve your indulgent fresh tuna casserole garnished with chopped fresh parsley leaves.
