Nordic-style vegetarian lasagne layered with garlic-sautéed spinach, grated heritage carrots and zucchini, rich béchamel sauce, and aged Västerbottensost cheese.
Wilt spinach with butter, minced garlic, and nutmeg; squeeze out excess liquid. Sauté grated carrots and zucchini until tender.
Melt butter, whisk in flour for 1 minute, then gradually whisk in warm milk until smooth. Simmer 5 minutes and stir in half the cheese and seasonings.
In a baking dish, layer béchamel sauce, pasta sheets, spinach, and grated vegetables. Repeat for 3 layers, finishing with béchamel.
Scatter remaining Västerbottensost on top. Bake at 200°C for 35 minutes until bubbling and golden. Rest 10 minutes before slicing.
