  • 1 small eggplant, thinly sliced
  • 1 zucchini, thinly sliced
  • 1 summer squash, thinly sliced
  • 2 small red skin potatoes, thinly sliced
  • 1 red bell pepper, thinly sliced
  • 1 1/2 cup marinara sauce
  • 3 cloves garlic, minced
  • 3 tsp fresh thyme, divided
  • 1-2 tbsp olive oil
  • pinch of red pepper flakes
  • salt and pepper
  1. Preheat the oven to 375 F. Lightly oil a 2-quart baking dish and set aside.

  2. Set your mandoline slicer to 1/4" thick and thinly slice all your vegetables. Set aside. 

  3. Evenly spread marinara sauce over the bottom of the baking dish. Top with minced garlic, red pepper flakes, 2 tsp of fresh thyme, salt and pepper. 

  4. Stack vegetables in a pattern and lay them in the baking dish. This can be done either in a spiral (as in the photos) or in rows if using a rectangular baking dish. 

  5. Drizzle with olive oil and sprinkle remaining thyme and pepper flakes over the top.

  6. Cover with tin foil and bake for 50-55 minutes until vegetables are tender and the marinara sauce is bubbling up from underneath. 

  7. Remove from oven and let cool 10 minutes before serving.
