Servings: 8
Ingredients
- 12 ounces thin spaghetti cooked al dente
- 6 tablespoons butter divided
- 16 ounces fresh mushrooms cleaned and sliced
- ½ medium sweet onion diced
- 4 tablespoons all purpose flour
- 2 cups milk
- 10-12 ounces solid white chunk tuna or albacore in water, drained
- 1 cup green peas frozen
- 1 cup Parmesan cheese shredded
- 1 cup bread crumbs
Instructions
- Preheat the oven to 350F.
- Spray a 9×13 pan with nonstick cooking spray.
- Cook the pasta al dente according to package directions, drain and set aside.
- In a large skillet, over medium heat, melt 4 tablespoons butter.
- Add mushrooms and cook until mushrooms are tender and lightly browned.
- Add the onion and cook for another 2-3 minutes or until it starts to soften.
- Sprinkle in the flour and stir to coat. Cook 1-2 minutes to remove raw flour taste.
- Whisk in milk, stirring constantly to make cream sauce.
- Stir in the tuna and peas. Season with salt and pepper to taste.
- Mix the tuna mixture with the cooked pasta.
- Spread into a prepared casserole dish.
- Sprinkle it with parmesan cheese.
- In a small bowl, melt the remaining 2 tablespoons butter.
- Stir in the bread crumbs and toss to coat.
- Spread over the top of the cheese.
- Bake for 25-30 minutes or until bubbly and the top is golden brown.
- Remove and let cool slightly.
Notes
- Cook the pasta 1 to 2 minutes short of the package directions so it stays al dente after baking.
- Add a splash of pasta water if the sauce seems too thick.
- Use crushed Ritz crackers for the topping if you want it extra buttery.
- Stir in cream of mushroom soup when reheating if the leftovers seem dry.
- Add extra Parmesan if you love it, because more cheese is rarely the wrong call.
