Instructions

1. Preheat the oven to 180C/ 350 F
2. Line two baking sheet with parchment paper.
3. Slice the zucchini into 1/4 rounds. Lay on baking sheet in one layer (more or less)
4. Peel the onion, and cut in half. Slice into 1/4 inch slices and place on other baking sheet.
5. Drizzle olive oil over both onions and zucchini. Add salt, pepper and thyme to both, tossing so everything is evenly coated. Place in oven and bake until done, and beginning to brown, about 20 minutes. If your oven is uneven, you may want to switch the trays half way through. Take out and let cool to handle.
6. In the meantime make your besciamella:
7. To make the besciamella heat up the milk without letting it boil.
8. In a small pan melt the butter. Add the flour with a sifter, stirring so that no lumps form. Keep stirring for another five minutes to make sure the flour loses it’s raw taste. Start to add the hot milk mixture, stirring all the while, to avoid lumps. Once all the liquid is incorporated, keep cooking over low heat until it is thickened, about 10 minutes. You want this sauce to be rather loose, since you will be using dried lasagna noodles.
9. To assemble the lasagna:
10. Line up your ingredients.
11. Ladle enough besciamella into each dish to cover the bottom. You don’t need a lot, about 2 tablespoons each.
12. Lay a layer of noodles. These will be rectangle so you’ll have to break them in half, and then use smaller pieces to fill in gaps. Don’t worry about filling every gap or what it looks like. You’ll want ot use about one noodle per layer.
13. Arrange a quarter of the zucchini in each bowl, on top .
14. Spoon some more besciamella on top. Then sprinkle with some grated parmesan.
15. Repeat with noodle layer. Top each dish with a quarter of the onions, and divide a cup of the mozzarella between the dishes. Top with a bit more parmesan and some more besciamella.
16. Finally top with the last layer of lasagna noodles, the rest of the besciamella, the last half cup of mozzarella and a sprinkling of parmesan.
17. Place in preheated oven and bake for 30 minutes, or until the top is browned and bubbly;
