Ingredients
  

  • 2 tbsp olive oil
  • 1 small red onion diced
  • ½ red bell pepper diced
  • 3 cups butternut squash peeled and cubed
  • 3 cloves garlic minced
  • 2 cups chopped kale stems removed
  • ½ tsp sea salt plus more to taste
  • ½ tsp black pepper
  • ½ tsp paprika
  • ½ tsp ground cumin
  • ½ tsp dried thyme
  • 4 large eggs
  • ¾ cup heavy cream or coconut cream for dairy-free
  • ¾ cup crumbled feta cheese

Instructions
 

  • Preheat your oven to 375°F.
  • Heat olive oil in a large oven-safe skillet over medium heat. Add the red onion, red bell pepper, and butternut squash all at once. Season with salt, black pepper, paprika, cumin, and thyme. Cook for about 10–12 minutes, stirring occasionally, until the squash begins to soften and caramelize slightly.
  • Stir in the minced garlic and chopped kale. Cook for another 2–3 minutes, just until the kale wilts and the garlic becomes fragrant.
  • In a medium bowl, whisk together the eggs. Season with salt, black pepper, paprika, cumin, and thyme then whisk in the heavy cream and crumbled feta until smooth and well combined.
  • Pour the egg mixture evenly over the sautéed vegetables in the skillet. Give it a gentle stir to distribute everything.
  • Transfer the skillet to the oven and bake for 30 minutes, or until the eggs are just set and the top is slightly golden.
  • Remove from the oven and let rest for a few minutes before serving.
  • Serve warm — perfect for a cozy brunch or light dinner with a side salad.

Notes

  • Dice the squash evenly. Even-sized cubes ensure the squash cooks at the same rate, preventing some pieces from becoming mushy while others stay underdone.
  • Use an oven-safe skillet. A cast-iron or stainless steel skillet works best since it goes from stovetop to oven safely. If you don't have an oven-safe skillet, you'll have to transfer the mixture to a baking dish!
  • Season in layers. Adding spices to both the vegetables and the egg mixture makes the flavor deeper and more balanced.
  • Let it rest before cutting. Giving the quiche a few minutes to settle helps it firm up, making it easier to slice cleanly. It also allows the flavors to meld together!
