Ingredients
  

SAUCE

  • 2 tbsp frying oil
  • 1 medium onion
  • 2 cloves garlic
  • 2 tbsp French seasoning Herbes de Provence (or mix of thyme and oregano)
  • 1 red bell pepper
  • 14 ounces crushed tomatoes
  • 1 tsp balsamic vinegar
  • salt and pepper to taste

VEGETABLES

  • 3 medium tomatoes
  • 1 medium zucchini
  • 1 medium yellow squash
  • 1 small eggplant
  • 3 medium potatoes
  • salt and pepper to taste
  • 1-1/2 cups shredded Gruyere or other melting cheese

Instructions
 

SAUCE

  • Chop the onion and bell paprika, cut the garlic very finely.
  • Heat the oil in a big frying pan over medium heat, add the onion and cook for about 5 minutes until soft and translucent.
  • Add the garlic and herbs, cook for 1 more minute.
  • Add the bell pepper, cook, stirring from time to time, for about 3 minutes, until softened.
  • Add the crushed tomatoes, stir and cook the sauce for about 10-15 minutes over low/medium heat (add some boiling water if the sauce is too dry). Add the balsamic vinegar and cook for 10 seconds.
  • Puree the sauce with a blender, season with salt and pepper to taste.

ASSEMBLE

  • While the sauce is cooking, prepare the vegetables: Peel the potatoes and tomatoes. Cut the zucchini, squash, tomatoes, and eggplant into thin, about 1/4 inch (5mm) slices, cut the potatoes a little thinner (you can use a sharp knife or a mandoline). Make sure you slice the potatoes more thinly than the rest of the vegetables.
  • Preheat the oven to 425°F / 220°C / Gas Mark 7, no fan.
  • Spoon the sauce into the baking dish, even out its surface. Note: if you're using a rectangular 9×13 inch (23cmx33cm) casserole dish use the whole amount of the sauce, if you're using an oval 9×13 inch (23cmx33cm) casserole dish, add a little less sauce – about 1/2-2/3 cup less sauce (you can use it for another recipe or bake it with the leftover vegetables that won't fit in your baking dish).
  • Arrange the vegetables in the baking dish in an alternating layered pattern from the outer edge to the inside until the entire baking dish is filled.
  • Sprinkle salt, pepper, and some more Herbes de Provence over the vegetables. Pour a small amount of olive oil over them.
  • Bake for 45 minutes (uncovered) until the sauce is bubbly and the vegetables are browned (if the vegetables are not browned you can turn on the fan or move the baking dish under the most upper rack / under the broiler and bake briefly until the edges of the vegetables are browned).
  • Sprinkle grated cheese over the vegetables and bake until the cheese is melted and slightly golden (on the top shelf for 5-10 minutes or under the broiler for about 1-2 minutes – be careful not to burn it).
  • Take the casserole out of the oven and leave to rest for about 15 minutes.

Notes

Gruyere is a Swiss semi-hard cheese that has a very pronounced flavor and melts well. It tastes amazing in this dish but if you can’t find it you can use other kinds of melting cheese, like gouda, Swiss cheese, or low-moisture mozzarella.
