1/2cupdiced onions (about half small yellow or white onion)
2cupspacked arugula shredded kale would also work
1/4cupchopped herbs (mix of 2 tbsp chopped parsley, 2 tbsp chopped chives or dill)
1/3cupshredded parmesan cheese
microgreens for garnish
Instructions
Preheat the oven to 350F and place a 10 inch skillet on the stovetop.
Whisk eggs, milk, ricotta, salt and pepper and set aside.
Prep other ingredients: dice onions, measure out herbs and arugula.
Add 3 tbsp olive oil to pan and turn to medium heat. Once pan is hot add onions and cook for 5-7 minutes to soften.
Stir in the arugula & herbs to just wilt, stirring to just wilt the greens, about 1 minute.
Pour the eggs & milk mixture into the pan, stir to incorporate the onions and greens in the pan and then leave to cook until the edges of the frittata just start to pull away from the pan, about 5-7 minutes.
Top with parmesan cheese and then transfer to the oven and bake to set, about 15-18 minutes. (When it's done the middle of the frittata will spring back when presssed with a finger).
Set aside to cool for a few minutes.
Slice and top with microgreens and serve with a side of bread & butter if so desired.
Notes
Make sure to let the frittata fully cool before storing in the fridge in an airtight container for up to 4-5 days.
To freeze, let the frittata fully cool and then wrap each slice in one layer of plastic wrap or parchment paper and then a second layer of foil - two layers helps to prevent freezer burn. Store the wrapped frittata slices in a ziploc bag or airtight container in the freezer for up to three months. Let frozen frittata slices defrost in the fridge overnight.
You can reheat frittata in the oven at 350F for 5 minutes or until warmed through. Alternatively you can warm in the microwave in 30 seconds increments until warmed through.
