Method

  1. 1

    Bring a large pot of salted water to the boil and cook the egg noodles until just al dente (slightly under the package instructions). Drain well and set aside.

    ~10 mins

    Tip: Do not overcook; the noodles will soften further in the slow cooker

  2. 2

    In a medium bowl, whisk together the condensed cream of mushroom soup and milk until smooth. Season with salt and black pepper.

    ~5 mins
  3. 3

    In your slow cooker, combine the cooked noodles, drained tuna, and soup mixture. Stir gently to combine, ensuring the noodles are evenly coated.

    ~3 mins

    Tip: Do not overmix; you want to keep some texture in the tuna

  4. 4

    Cover and cook on Low for 4 hours or High for 2.5 hours, until the mixture is hot and bubbling gently at the edges.

    ~4 hrs

    Tip: The exact time depends on your slow cooker; start checking at 2 hours on High

  5. 5

    In the final 30 minutes of cooking, stir in the grated cheddar cheese and panko breadcrumbs (if using). Stir well to combine.

    ~1 min

    Tip: Adding these at the end preserves the melting quality of the cheese and crunch of the breadcrumbs

  6. 6

    Once heated through and the cheese is melted, taste and adjust seasoning as needed. Serve hot, garnished with fresh parsley if desired.

    ~5 mins

    Tip: This dish is best served immediately whilst warm and creamy

Frequently Asked Questions

Yes, you can use 400g of flaked fresh cooked tuna. However, tinned tuna is traditional in this comfort food classic and offers excellent convenience and reliability. If using fresh, add it only in the final 30 minutes to prevent it becoming tough
