Step-by-Step Instructions

Step 1: Preheat the oven to 210°C (410°F) until it’s warm, then cook the pasta as instructed on the package until it’s halfway done. After that drain the water and let it sit for a bit.

Step 2: While the pasta is boiling, grab a medium-sized pot and melt the butter over low heat, then add the onion and garlic — Cook them for about 5 minutes until they’re soft and fragrant.

Step 3: Pour the flour into the pot and mix it until it becomes dough, then pour about a third of the milk and stir it really quickly. Repeat this two more times until all the milk is blended in and the mixture is smooth.

Step 4: Turn the heat up to high, then pour in the broth, heavy cream, drained tuna, peas, corn, and lemon juice. Keep stirring until the sauce starts to boil — Tip: Don’t overdo the lemon juice, it keeps the dish from smelling too fishy!

Step 5: Turn off the stove and mix in half a cup of cheddar cheese until it melts. Give it a little taste and add salt and pepper if you think it needs it.

Step 6: Put the cooked pasta in a baking dish, then pour that whole big pot of creamy sauce over it and mix it well.

Step 7: Sprinkle the rest of the cheddar and Parmesan cheese on top. Bake it for 25 minutes until the cheese is golden and bubbly.

Notes

  • Grate your cheese from a whole block instead of using pre-shredded cheese to avoid anti-caking agents and get a smoother sauce.
  • Storage: Keep leftovers in an airtight container in the fridge for up to 3 days, or freeze them for up to 2 months.
