Print Recipe


  • Mandolin


  • 1 big onion, peeled and sliced
  • 2 tbsp cooking oil
  • 4 sliced tomatoes
  • 2 sliced zucchini
  • 4 medium peeled and sliced potatoes
  • 3 tbsp olive
  • 1 lb ground beef
  • salt, to taste
  • Black pepper, to taste
  • 2 tsp Garlic powder
  • 1 tbsp thyme (fresh or dried)
  • 1 cup grated cheese


The base

  • Preheat a skillet on medium heat, then add 2 tbsp cooking oil. Add the thinly-sliced onions. Allow them to sweat and caramelize. It will take about five to eight minutes.
  • Transfer the caramelized onion into a casserole dish.

Prepare the vegetables

  • It is better to use a mandolin to slice the veggies. Having the same thickness ensures even cooking.

Put it together

  • Preheat the oven at 375 F
  • Arrange the vegetables by lining them in a pattern: potato, tomato, and zucchini.
  • Once done, season with salt, pepper, a sprinkle of garlic powder and thyme. Then drizzle the olive oil all over the vegetables.
  • Cover with aluminum foil, and bake at 375 for 40 minutes.
  • Remove the foil and top it with the shredded cheese.
  • Put back in the oven for 15 minutes or until the cheese has melted.



  • Add meat patties between the veggies. 
  • Use pepper rings, eggplants, or winter squash.
  • Mushrooms are a good addition to the caramelized onions.
