Cook vegetables:
Peel and finely chop the shallots (or onion) and the garlic. Keep them separated. 3 shallots + 2 garlic cloves Prepare vegetables: Cut the peeled carrots, bell peppers, and zucchini into small cubes. Set them aside in a bowl. Divide the broccoli into small florets and chop the broccoli stem into small cubes. Add to the rest of the vegetables. 2 carrots + 2 bell peppers + 1 medium zucchini + ½ broccoli (or just the whole stem) Mushrooms: Wipe them clean with a paper towel and slice them thinly. Set aside in a different bowl. 7 oz/ 200 g mushrooms Defrost the peas. 7 oz/ 200 g frozen peas Preheat the oven to 375°F/ 180°C.
Cook mushrooms: Heat 2 tablespoon olive oil in a large pan and fry the mushrooms until golden and all the released juices are evaporated. Remove them from the pan.
Saute shallots and garlic: Heat the remaining oil in a pan and cook the shallots until translucent, about 2-3 minutes. Add the garlic and stir for 1 minute. Add the sugar and stir for another minute or until slightly caramelized. 2 tablespoon olive oil + ½ teaspoon sugar Add the chopped vegetables (except the mushrooms) and cook for about 8 minutes or until softer. Stir well a few times in between.
Simmer vegetable sauce: Add the chopped tomatoes, water, dried herbs, and lemon juice. Stir well, bring to a boil, and simmer the sauce for about 10 minutes until slightly thickened. 2 cans chopped tomatoes 14 oz/ 400 g each + ½ cup/ 125 ml water + ½ teaspoon oregano + ½ teaspoon rosemary + ½ teaspoon thyme + 1 tablespoon lemon juice Adjust the taste with salt, pepper, lemon juice, and a bit of extra sugar if necessary. 1 tablespoon lemon juice, salt, pepper and sugar to taste
Assemble the vegetable lasagna:
Butter the baking dish with about 1 teaspoon of butter.
Cheese: Chop the mozzarella into cubes and grate the Parmesan. Set them aside in different bowls. 2 mozzarella balls + 3.5 oz/ 100 g Parmesan You should have 3 layers of noodles and finish with a layer of Parmesan.
First layer: Cover the bottom of the buttered dish with a few tablespoons of white sauce. Add a layer of lasagna sheets (they should not overlap). Cover with ⅓ of the vegetable sauce. Add ½ of the mozzarella and ⅓ of the Parmesan. Cover with ⅓ of the white sauce.
Second layer: Lasagna sheets + ⅓ of the vegetable sauce + ½ of the mozzarella + ⅓ of the Parmesan + ⅓ of the white sauce.
Third layer: Lasagna sheets + remaining veggie sauce + remaining white sauce +remaining Parmesan.
Bake vegetable lasagna:
Bake for 30-40 minutes or until bubbling and golden. Check if the noodles are cooked through by inserting a fork into the lasagna.
Rest for 10-15 minutes, cut into 12 squares, and serve.
- Lasagna sheets: I needed 9 sheets of no-boil lasagna sheets. Use more or less according to the size of the lasagna sheets; you should have 3 layers of noodles. If using lasagna sheets that need to be cooked before baking, boil them according to the package instructions. However, I have never tested this recipe with this type of lasagna sheet; they don’t exist where I live.
- Vegetables: About 1.5 lb/ 750 g vegetables, not including canned tomatoes.
- You can vary the vegetables according to what you have or like. For instance: eggplants, cauliflower, green beans, small fennel, parsnips, pumpkin or butternut squash, some celeriac, etc.
- Or use only broccoli stems.
- Cremini or white mushrooms. You can replace them with more of the other vegetables if you wish.
- Parmesan is not vegetarian. To keep the dish vegetarian, please use vegetarian hard cheese.
