Boil 4 quarts of water. Salt water and cook egg noodles until slightly al dente (about 1 minute less than package instructions). Drain, coat with a little olive oil, and set aside.
In a large pot, melt butter. Add diced onion, garlic, and a pinch of salt. Cook until onion softens (3-4 minutes).
Add mushrooms with another pinch of salt. Sauté until mushrooms are softened and lightly browned, about 4 minutes.
Stir in flour and cook for 1 minute. Stir in chicken stock, then add bouillon, salt, Dijon, heavy cream, and cream cheese. Stir until smooth and velvety.
Add cooked noodles, tuna (crumbled), frozen peas, cheddar, parmesan, and black pepper. Fold together, adding 30-40g (2-3T) water if it looks too dry.
Transfer to a 9x13 casserole dish. Top with fried panko and additional grated parmesan.
Bake at 425°F/200C for 20-25 minutes until golden and bubbly.
For fried panko breadcrumbs: Heat sauté pan over medium high and add 50g or 4T olive oil. Once shimmering, add breadcrumbs. Toss to combine. Add pinch of salt. Continue stirring and tossing while cooking to a nice golden brown for about 60 seconds. Keep a close eye on these. They brown very quickly. Remove from pan and allow to dry and cool on a towel.
