These delectably sweet and juicy pale yellow onions are available for a short time only—from May through June. When those months come along, that means it's the perfect time to make this delicious, savory onion tart. This recipe also features kalamata olives, fresh thyme, and shredded Swiss cheese. Keep in mind when you're buying your onions that you should store them in a cool, dark place or in the refrigerator, and be sure to allow for good air circulation to keep them as fresh as possible. And if you can’t find any vidalia onions, Texas Sweets and Walla Wallas are good alternatives.


Olive oil

½ tsp

Uncooked vidalia onion(s)

1 large, (about 3/4 pound), thinly sliced


¼ cup(s)

Table salt

¼ tsp


4 medium, kalamata, pitted and chopped

Fresh thyme

1 tsp, fresh, chopped

Black pepper

¼ tsp, freshly ground

Phyllo dough

2 sheet(s), (12 x 17-inch) sheets, at room temperature

Swiss cheese

2 Tbsp, shredded, Jarlsberg variety, shredded


  1. Heat the oil in a medium nonstick skillet over medium-high heat. Add the onion, water, and salt; bring to a boil. Reduce the heat and simmer, covered, stirring occasionally, until the onion is very soft, about 20 minutes. Remove from the heat and stir in the olives, thyme, and pepper; cool slightly.
  2. Preheat the oven to 400°F.
  3. Place 1 phyllo sheet on a dry work surface; lightly spray with nonstick spray. As you work, keep the sheets of phyllo covered to keep them from drying out. Top with a second phyllo sheet; lightly spray with nonstick spray. Cut into 4 rectangles. Place the rectangles on top of each other to form a stack. Roll the edges of the phyllo in to make a small rimmed edge; place on a baking sheet.
  4. Spread the onion mixture evenly over the phyllo. Bake the tart until the edges are golden brown, about 20 minutes. Sprinkle the tart with the cheese and bake until the cheese melts, about 5 minutes longer. Yields 1/2 tart per serving.
