- 1 (10 ounce) box frozen chopped spinach
- 1 lb shell pasta (medium or large, with ridges)
- 1 tablespoon extra virgin olive oil
- 2 tablespoons butter, cut into pieces
- 1 medium onion, finely chopped
- 5 garlic cloves, minced
- 3 tablespoons all-purpose flour
- 1⁄2 cup dry white wine
- 1 cup chicken broth
- 2 cups milk
- 1⁄4 teaspoon grated fresh nutmeg
- 1 teaspoon hot sauce
- 1 teaspoon Dijon mustard
- black pepper
- 2 (6 ounce) canswhite tuna in vegetable oil, drained
- 1 cup grated parmigiano-reggiano cheese
- 2 -3 tablespoons chopped fresh flat-leaf parsley
- Place spinach on a plate and microwave it for 6 minutes on HIGH to defrost it; place it in a clean kitchen towel and wring it dry; set aside.
- While the spinach is defrosting, get a big pot of water on the stove; bring to a boil; then salt the water liberally and cook the shells to al dente.
- While the pasta cooks, heat a deep large skillet over medium heat.
- Add in the olive oil, then melt the butter into the oil.
- When the butter melts, add in the onions and garlic; cook 4-5 minutes until tender.
- Sprinkle the flour around the pan and cook for a minute, then whisk in the wine—it will cook off and the mixture will thicken almost immediately.
- Whisk in the stock, then whisk in the milk and bring it to a bubble.
- Reduce heat slightly; season the sauce with nutmeg, hot sauce, and mustard; season with salt and pepper to taste.
- Simmer 2-3 minutes to thicken; then add in the spinach, separating it as you add it to the sauce.
- Preheat the broiler.
- Back to the sauce, add in the tuna, flaking it as you go; then stir to combine.
- Heat the spinach and tuna for a minute or so.
- Drain the pasta and toss with the sauce.
- Transfer mixture to a casserole dish; cover it with the cheese.
- Place the casserole under the broiler for 2 minutes to brown the edges and the cheese.
- Top with parsley and serve.
