Ingredients

  • 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 ½ cup marinara sauce
  • 3 cloves garlic, minced
  • 3 teaspoon fresh thyme, divided
  • 1-2 tablespoon olive oil
  • pinch of red pepper flakes
  • salt and pepper

Instructions

  • Preheat the oven to 375 F. Lightly oil a 2-quart baking dish and set aside.
  • Set your mandoline slicer to ¼" thick and thinly slice all your vegetables. Set aside. 
  • Evenly spread marinara sauce over the bottom of the baking dish. Top with minced garlic, red pepper flakes, 2 teaspoon of fresh thyme, salt, and pepper. 
  • 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. 
  • Drizzle with olive oil and sprinkle remaining thyme and pepper flakes over the top.
  • Cover with tin foil and bake for 50-55 minutes until vegetables are tender and the marinara sauce is bubbling up from underneath. 
  • Remove from the oven and let cool 10 minutes before serving. 

Notes

Serving and Storing - Serve with some crusty artisan bread, and a kale Caesar Salad. Store leftovers in an airtight container in the refrigerator for 2 days. Gently reheat in the oven or microwave.
Recipe Tips - When picking out your veggies, try and find vegetables that all have a similar width. That means look for skinny eggplants and fat zucchinis and summer squash. This both affect the appearance of the dish as well as baking quality.
