Serves: 8 Prep Time: Cooking Time: Nutrition facts: 200 calories 20 grams fat


  • 1 ½ cups (225 g) all-purpose flour
  • ¾ cup (75 g) grated Parmesan cheese
  • 3 Tbsp (24 g) cornstarch
  • 1 Tbsp (12 g) granulated sugar
  • 2 tsp dried oregano or Herbes de Provence
  • 1 ½ tsp baking powder
  • ½ tsp fine salt
  • 6 Tbsp (90 mL) sour cream
  • 6 Tbsp (90 mL) 2% milk
  • 2 large eggs
  • 6 Tbsp + 1 Tbsp (105 g) unsalted butter, melted
  • 3 to 4 medium cooking onions
  • 1 Tbsp (30 mL) olive oil


  1. Preheat the oven to 400°F (200°C). Have a 9-inch (23 cm) heavy-bottomed ovenproof skillet ready.
  2. Make the cake batter. Stir the flour, Parmesan, cornstarch, sugar, oregano or Herbes de Provence, baking powder, and salt. Whisk the sour cream, milk, and eggs in a bowl and add this all at once to the flour, stirring just until combined. Stir in the melted butter (the batter will be thick) and set aside.
  3. Peel and cut the onions into ½-inch (1.2 cm) thick slices and leave the rings intact (do not separate the rings of the onions).
  4. Cook the onions. Heat the skillet over medium-high heat. Add the remaining 1 Tbsp (15 mL) of butter and oil and swirl to coat the pan. Once the butter stops bubbling, arrange the onions to completely fill the bottom of the pan, placing them as close together as you can without them overlapping. Let the onions cook for about 4 minutes until you start seeing the edge of the rings starting to brown.
  5. Top the onions with the cake batter. Remove the pan from the heat and dollop the batter over the onions, using a spatula to gently spread the batter evenly over the onions to cover them. Put the pan in the oven and bake immediately reduce the oven temperature to 375°F (190°C).
  6. Bake the cake for about 25 minutes, until a tester inserted in the center of the cake comes out clean. Cool the cake in its pan for about 20 minutes before inverting the pan to tip the cake out onto a plate. Serve the cake warm or at room temperature
