Rinse the salmon fillets and pat them dry. Then, cut into cubes. Season with salt and pepper. Drizzle lemon juice on top. Sear them briefly in a pan with a bit of neutral cooking oil.
Cook the pasta according to package directions until al dente.
Meanwhile, peel and finely chop the garlic. Rinse the dill and chop it into fine strips. Grease a baking dish with oil. Preheat the oven to 400°F.
In a bowl, combine the cream cheese, heavy cream, and vegetable broth. Season with salt, pepper, and nutmeg. Separate the eggs and add the yolks. Mix everything until a creamy sauce results. Both hand-mixing and using a hand mixer are fine options.
Drain the cooked pasta and place in the baking dish. Spread the frozen peas and garlic on top. Add the seared salmon and pour the cream over everything. Finally, sprinkle with grated cheese and bake for about 30 minutes at 400°F, or until golden.
