Salt
Pepper
Nutmeg
Preparation
Filling: Sauté minced onion with the crushed garlic and some cooking oil in a pan on low-medium heat. Add frozen, minced Spinach to the pan and cover, stirring occassionally until heated through. Let it cook for a bit without the cover to evaporate excess water. (important, otherwise the lasagna will turn out watery) Add seasoning.
Béchamel sauce: Add all ingredients to a separate pan on medium heat, whisk the entire time until the sauce starts to cook and thicken. Add seasoning.
Layering the lasagna: 1) Spinach filling 2) Lasagna sheet(s) 3) Sauce 4) Shredded cheese (save enough for finishing off the lasagna) Repeat until you run out of filling/sauce. Finish off the lasagna with a final layer of pasta sheet(s), sauce and shredded cheese
Bake at 200°C (air convection oven 180°C) for about 45-50 minutes in the middle, move lasagna up the last 10 minutes until golden brown.
