Ingredients

For the Tuna Mornay Base

2 tbsp (30 g) butter – for that classic creamy base.
2 tbsp (15 g) all-purpose flour – thickens the sauce beautifully.
2 cups (500 ml) milk – full-fat or low-fat both work.
1/2 cup (120 ml) chicken or vegetable stock – adds depth of flavor.
1/2 cup (50 g) shredded cheddar cheese – or use a mix of cheddar and mozzarella for extra melt.
2 tbsp (30 ml) cream or evaporated milk – optional, for extra richness.
1 tsp Dijon mustard – adds a subtle tang that brightens the sauce.
1/4 tsp ground nutmeg – the secret ingredient for that nostalgic warmth.
Salt and pepper, to taste

Protein & Add-ins

2 cans (185 g each) tuna in spring water or brine, drained and flaked.
2 cups (250 g) cooked elbow macaroni or penne – any short pasta works well.
1/2 cup (60 g) frozen peas – classic touch of sweetness and color.
1/4 cup (40 g) corn kernels – optional, but adds a lovely bite.
1 small onion, finely chopped and sautéed – adds a mellow base flavor.

Topping

1/2 cup (30 g) panko breadcrumbs – for irresistible crunch.
1 tbsp melted butter – to help the topping brown.
1 tbsp grated parmesan – adds a savory finish.
Fresh parsley, chopped – for garnish.

Substitutions:

Tuna: Use canned salmon or shredded cooked chicken.
Cheese: Try Swiss, Colby, or Gruyère for a different flavor.
Gluten-free: Use GF pasta and cornstarch instead of flour.
Dairy-free: Use plant-based milk, vegan cheese, and olive oil instead of butter.

Step-by-Step Instructions

1. Prepare Your Pasta and Ingredients (5 min)

Cook the pasta in salted boiling water until just al dente. Drain, rinse briefly under cold water, and set aside.

Pro tip: Slightly undercooked pasta finishes cooking in the oven, keeping it perfectly tender not mushy.

2. Make the Creamy Mornay Sauce (10 min)

In a medium saucepan, melt butter over medium heat. Whisk in flour to form a smooth paste (a roux). Cook for 1–2 minutes to remove the raw flour taste.
Gradually whisk in milk and stock, stirring continuously until smooth and thickened.
Add cheese, mustard, nutmeg, salt, and pepper. Stir until the sauce is velvety and coats the back of a spoon.

Visual cue: The sauce should cling slightly to your whisk glossy and smooth, not grainy.

3. Combine Everything (5 min)

In a large mixing bowl, combine the cooked pasta, tuna, sautéed onion, peas, and corn. Pour over the Mornay sauce and gently fold until everything is coated.

4. Assemble & Top (2 min)

Transfer the mixture to a greased baking dish.
In a small bowl, mix panko, melted butter, and parmesan. Sprinkle evenly over the top.

5. Bake to Perfection (15 min)

Bake at 180°C / 350°F for about 15–20 minutes, or until the top is golden and bubbling.

Pro tip: Switch to broil/grill for the last 2 minutes for an ultra-crispy crust.

6. Garnish & Serve

Sprinkle fresh parsley over the top and serve warm straight from the dish for that cozy, family-style presentation.
