Chef Walter’s Flavors + Knowledge: Concia of Vegetables

Wednesday, February 05, 2014


Concia means “blending”, therefore a combination of a variety of vegetables to choice and seasonally selected. Usually served as an accompaniment to roasts and seafood, Concia may also be served as a light, healthy lunch option. Serve in your favorite casserole or as in this version in individual servings. Every regions and cooks prepare their own Concia and the limit is your imagination. The dish has Jewish roots from the Roman Ghetto of Porta Ottaviana and historically the ingredients were limited to three.


Concia of Vegetables:

Prep Time: 1 hour, 30 minutes

Cook Time: 45 minutes

Total Time: 2 hours, 15 minutes


  • 1 -1/3 pounds (600 g) ripe plum tomatoes, blanched, peeled, seeded, chopped & drained (in winter canned tomatoes will do)
  • 1 pound (500 g) eggplant
  • 1 pound (500 g) zucchini cut in small dice
  • 1 pound (500 g) potatoes, peeled and sliced
  • 1 pound (500 g) white onion, thinly sliced
  • 2 ribs celery, finely minced
  • 2 tablespoons fresh oregano, finely minced
  • 2 cloves garlic, minced
  • 3 tablespoons Italian parsley, minced
  • Olive oil
  • Kosher salt & freshly ground pepper to taste


  • Trim the stems and bottoms of the eggplant, slice them finely, salt them, and put them in a colander for about an hour, during which time the salt will draw out the bitter juices. Then rinse them and pat them dry.
  • Preheat your oven to 360 F (180 C).
  • Oil a large oven-proof dish and put down the sliced vegetables in layers, seasoning each completed cycle with some of the minced herbs, salt and pepper, and a little olive oil. When you are done layering, sprinkle a little more olive oil over the top and bake until the vegetables are fairly dry.
  • Yield: 6 servings of Concia
