I love my tuna casserole because it is made from freshly poached tuna, sauteed mushrooms and shallots, along with a creamy homemade sauce created from heavy cream. You can use half-n-half but I don't use much to make the sauce. Just enough to pull all the ingredients together and serve. BTW, mine does not get baked in the oven.
Ingredients:
1/2 loaf day-old crusty bread or 2 crusty day-old rolls
1 1/4 pounds tuna steaks (2 big steaks 1 -inch thick each)
1 c. white wine
water
1 bay leaf
1 t. peppercorns
1 T. extra virgin olive oil
4 T butter, divided
2 large shallots, chopped
About 16 small button mushrooms, thinly sliced
Salt and freshly ground black pepper
1 1/2 t. ground thyme, or you can use poultry seasoning
2 T. all-purpose flour
1 1/2 c. chicken stock
1/2 c. heavy cream or half-n-half
1 c. baby frozen peas
1 pound extra-wide egg noodles, cooked to al dente or 12 ounces egg fettuccine (1 box)
Chopped fresh parsley leaves, to garnish
Directions:
Place bread in warm oven, 250 degrees F, to dry and toast, 20 minutes. Place tuna in a skillet and add wine, then water - just enough to cover fish. Add bay leaf and peppercorns. Bring liquids to a boil. Reduce heat to simmer and cover skillet. Poach fish for 12 minutes.

Heat a large skillet over medium heat. Add oil and 2 Tablespoons of butter - reserve remaining 2 Tablespoons butter. Add shallots and mushrooms and season with salt and freshly ground black pepper. Saute gently for 5 minutes. Sprinkle in ground thyme and flour and cook flour 1 minute, stirring with a whisk or wooden spoon. Whisk in stock, then cream. Adjust seasonings. Add peas.
Remove cooked, poached tuna to a bowl and flake fish with a fork.
Add cooked noodles and tuna to sauce. Remove sauce from heat and transfer mixture to a casserole or serving dish. Use the widest cutting edge on a box grater to grate the bread into large crumbs. Melt remaining 2 Tablespoons butter in a small cup in microwave and pour melted butter over bread. Scatter buttery bread crumbs and parsley over the top of the casserole. Serve immediately with a nice salad and glass of white wine.
