So, let’s dive into this timeless recipe and rediscover the magic of Tuna Mornay!
Ingredients:
- For the Tuna Mornay:
- 2 (5 ounce) cans tuna, drained
- 4 tablespoons butter
- 1/4 cup all-purpose flour
- 3 cups milk
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon nutmeg
- 1 cup shredded Gruyere cheese, divided
- 1/2 cup grated Parmesan cheese, divided
- 1 tablespoon Dijon mustard
- 1 tablespoon lemon juice
- 1/4 cup chopped fresh parsley
- For the Pasta:
- 1 pound elbow macaroni or other pasta shape
- Water for boiling
- 1 tablespoon salt for pasta water
- Optional Toppings:
- Breadcrumbs (panko or regular)
- Extra Parmesan cheese
- Paprika
Preparing the Pasta:
- Boil the water: Fill a large pot with water, about 6-8 quarts. Add 1 tablespoon of salt. Bring the water to a rolling boil over high heat. The salt seasons the pasta as it cooks.
- Cook the pasta: Once the water is boiling, add the elbow macaroni (or your preferred pasta shape). Stir the pasta to prevent it from sticking together.
- Cook to al dente: Cook the pasta according to the package directions, usually around 8-10 minutes, or until it is al dente. Al dente means “to the tooth” in Italian, and the pasta should be firm to the bite, not mushy. This is important because the pasta will continue to cook slightly in the sauce.
- Drain the pasta: Once the pasta is cooked, drain it immediately in a colander. Do not rinse the pasta unless you are not using it right away. Rinsing removes the starch, which helps the sauce adhere to the pasta. If you are not using the pasta immediately, rinse it with cold water to stop the cooking process and prevent it from sticking together.
- Set aside: Set the drained pasta aside while you prepare the Tuna Mornay sauce.
Making the Tuna Mornay Sauce:
- Melt the butter: In a large saucepan or Dutch oven, melt the butter over medium heat. Make sure the butter doesn’t burn.
- Make a roux: Once the butter is melted, add the flour. Whisk constantly for 1-2 minutes until the flour and butter form a smooth paste, called a roux. This is the base of the Mornay sauce and helps to thicken it. Cook the roux for a minute or two to cook out the raw flour taste.
- Gradually add the milk: Slowly pour in the milk, about 1/2 cup at a time, whisking constantly to prevent lumps from forming. Make sure each addition of milk is fully incorporated before adding more. This is crucial for a smooth sauce.
- Simmer and thicken: Continue whisking the sauce over medium heat until it begins to simmer and thicken. This should take about 5-7 minutes. The sauce should be thick enough to coat the back of a spoon.
- Season the sauce: Once the sauce has thickened, remove it from the heat. Stir in the salt, pepper, and nutmeg. The nutmeg adds a subtle warmth to the sauce.
- Add the cheese: Add 3/4 cup of the shredded Gruyere cheese and 1/4 cup of the grated Parmesan cheese to the sauce. Stir until the cheese is melted and the sauce is smooth and creamy. Reserve the remaining cheese for topping.
- Stir in Dijon and lemon juice: Stir in the Dijon mustard and lemon juice. The Dijon mustard adds a tangy flavor, and the lemon juice brightens the sauce.
- Add the tuna: Gently fold in the drained tuna. Be careful not to break the tuna into small pieces; you want to keep some texture.
- Add the parsley: Stir in the chopped fresh parsley. The parsley adds a fresh, herbaceous note to the sauce.
Combining and Baking (Optional):
- Preheat the oven (if baking): If you are baking the Tuna Mornay, preheat your oven to 375°F (190°C).
- Combine pasta and sauce: Add the drained pasta to the saucepan with the Tuna Mornay sauce. Gently toss to coat the pasta evenly with the sauce.
- Transfer to baking dish (if baking): If you are baking the Tuna Mornay, transfer the pasta and sauce mixture to a greased 9×13 inch baking dish.
- Top with cheese and breadcrumbs (optional): Sprinkle the remaining Gruyere and Parmesan cheese over the top of the pasta. If desired, sprinkle breadcrumbs over the cheese for a crispy topping. You can also add a dash of paprika for color.
- Bake (if baking): Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly and the topping is golden brown.
- Serve immediately (if not baking): If you are not baking the Tuna Mornay, you can serve it immediately after combining the pasta and sauce.
Serving Suggestions:
- Garnish: Garnish with extra chopped fresh parsley or a sprinkle of paprika.
- Side dishes: Serve with a side salad or steamed vegetables for a complete meal.
- Wine pairing: A crisp white wine, such as Sauvignon Blanc or Pinot Grigio, pairs well with Tuna Mornay.
- Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven.
Tips and Variations:
- Cheese variations: Feel free to experiment with different types of cheese. Cheddar, Monterey Jack, or Havarti would also be delicious in this recipe.
- Vegetable additions: Add cooked vegetables, such as peas, carrots, or broccoli, to the sauce for added nutrition and flavor.
- Spice it up: Add a pinch of red pepper flakes to the sauce for a little heat.
- Creamier sauce: For an even creamier sauce, add 1/4 cup of heavy cream or sour cream to the sauce at the end.
- Breadcrumb topping: For a crispier breadcrumb topping, toss the breadcrumbs with melted butter before sprinkling them over the pasta.
- Make it ahead: You can prepare the Tuna Mornay sauce ahead of time and store it in the refrigerator for up to 2 days. When ready to serve, cook the pasta and combine it with the sauce.
- Gluten-free option: Use gluten-free pasta and gluten-free flour to make this recipe gluten-free.
- Lower-fat option: Use skim milk and reduced-fat cheese to make this recipe lower in fat.
- Tuna substitution: Canned salmon or cooked chicken can be substituted for the tuna.
- Pasta shape: While elbow macaroni is traditional, other pasta shapes like penne, rotini, or shells work well too. Choose a shape that holds the sauce well.
Troubleshooting:
- Lumpy sauce: If your sauce becomes lumpy, try whisking it vigorously or using an immersion blender to smooth it out. You can also strain the sauce through a fine-mesh sieve.
- Thick sauce: If your sauce becomes too thick, add a little more milk to thin it out.
- Thin sauce: If your sauce is too thin, continue to simmer it over low heat until it thickens. You can also add a cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons cold water) to the sauce to thicken it.
- Burnt sauce: If your sauce burns, immediately transfer it to a clean saucepan. Be careful not to scrape the burnt bits from the bottom of the pan into the new saucepan.
