Ingredients
- 2 medium, peeled and diced into 1/4-inch cubes sweet potatoes
- 1 tbsp avocado oil
- 6 large eggs
- 2 cups, roughly chopped fresh spinach
- 1 cup, thinly sliced cremini mushrooms
- 1 tbsp, finely chopped fresh thyme leaves
- 1/4 tsp sea salt
- 1/8 tsp black pepper
Instructions
- Step 1: Preheat oven to 400°F. Toss 2 medium peeled and diced sweet potatoes with 1 tbsp avocado oil, then spread in a single layer on a parchment-lined baking sheet. Roast for 20-22 minutes until golden and tender, flipping halfway through.

- Step 3: Sauté 1 cup thinly sliced cremini mushrooms in a 10-inch oven-safe skillet over medium heat for 4-5 minutes until golden brown, then stir in 2 cups chopped fresh spinach until wilted, about 1 minute.
- Step 4: Pour the egg mixture over the mushroom-spinach base, then top with the roasted sweet potatoes. Bake for 15-18 minutes until the edges are golden and the center is set.
