Ingredients

½ Tablespoon olive or avocado oil
½ medium yellow onion thinly sliced
2 cloves garlic
1 red bell pepper cored, seeded, and chopped
2 cups fresh baby spinach roughly chopped
¾ teaspoon sea salt divided
Cracked pepper to taste
10 large eggs
½ cup unsweetened almond milk
2 ounces chèvre soft goat cheese or Boursin cheese
Fresh parsley for serving

Instructions

Preheat the oven to 400ºF.
Add oil to ovenproof skillet (I used a 10 inch cast iron) over medium heat. Add the onion, ¼ tsp salt and a crack of pepper. Sauté until tender and golden, 8-10 minutes. Add the bell pepper and garlic and sauté for another 5 minutes. Add the spinach and cook for another minute, until just wilted.
Crack the eggs into a large bowl, add milk, remaining salt and a crack of pepper and beat well with a whisk. Pour the beaten eggs into the skillet and use a spatula/spoon to press the vegetables down into the egg mixture so that the eggs cover the veggies completely.
Crumble the chèvre over the top, then place the pan in the oven and bake until the middle is set and top is lightly golden, about 10-12 minutes
Cut into 4 wedges and serve warm with fresh parsley.

Notes

Storing: Store leftover frittata slices in an airtight container in the fridge for up to 4 days. Let them cool before storing to prevent condensation.
Reheating: Warm up slices in the microwave for about 30 seconds or in a skillet over low heat for a few minutes until heated through. You can also pop them in the air fryer at 300ºF for a few minutes to get the edges crispy again!
Freezing: If you want to keep leftovers longer, freeze individual slices in an airtight container for up to 2 months. Let them thaw in the fridge overnight before reheating.
