Author Notes
My frittata game started several years ago with Cookie and Kate's first guide to making frittatas (she's since created an updated version). The first few times I made frittatas, I just threw together some veggies, milk, cheese and eggs. I really dug the easiness and healthiness of this "chuck it together and wack it the oven" approach, but I knew frittatas could be better.
Since then I've upped my cooking skillz a ton, so the traditional frittata method (starting on the stove and finishing in the oven) has become much less intimidating. I've found that this frittata method yields a more custardy, less spongey frittata.
My upgrade from spongey frittata could also be due to some other factors, like avoiding watery raw veggies, using whole milk and not overbaking. Take my mistakes and learn from them, friends: the best frittatas use cooked veggies and fatty milk, and are just barely set in the middle.
The flavor mélange in this frittata recipe is a real banger. Sweet caramelized onions, slightly spicy parsnips, salty parm and fresh thyme...the combo is really one for the record books. —Sustained Kitchen - Molly
Ingredients
-
2 tablespoons
olive oil
-
2 cups
onions, thinly sliced (about 2 medium onions)
-
2 cups
parsnips, thinly sliced (about 4 medium parsnips)
-
10
large eggs
-
1/3 cup
whole milk
-
1/2 cup
grated parmesan cheese
-
2 tablespoons
chopped thyme
-
salt and pepper to taste
Directions
- Preheat your oven to 350 F. Heat about a tablespoon of olive oil in a 12-inch cast iron skillet or oven-safe non-stick skillet over medium-high. Slice onions into thin strips and place them into the skillet, along with a sprinkle of salt. If your pan gets too crowded before you've added all the onions, let them cook down a bit before adding more. Once all your onions are in the pan, turn the heat down to medium low and let them cook, stirring occasionally until caramelized, about 15-20 minutes.
- Meanwhile, slice your parsnips into thin circle or semi-circles. Set these aside until your onions are a caramelized. Then, add your parsnips and bit more salt to the pan. Let the parsnips cook with the onions until tender, about 10 minutes. If your skillet gets a little too dry, add a little broth, water or white wine to deglaze. Once your parsnips are cooked through, turn off the heat, remove the vegetables from the pan and set aside.
- Whisk together your eggs, milk, cheese, thyme, about 1/2 teaspoon salt, and pepper to taste. Add your vegetables to the egg mixture and stir.
- Place your skillet back over medium heat with about a tablespoon of olive oil. Once the pan is hot, pour your egg mixture into the skillet, using a spatula to gently scrape the cooked egg off the bottom of the pan. Do this for about 2 minutes and then transfer your skillet to the oven. Bake for about 12-18 minutes, or until it jiggles just slightly in the middle when shaken. Serve immediately.
