Protein-packed broccolini frittata with mushrooms and feta cheese in under 30 minutes! Enjoy it for breakfast, lunch, or dinner paired with a salad or your favorite bread!
8 large eggs (can substitute 2 egg whites for one egg)
1/3 cup of whole milk
1/2 cup shredded parmesan cheese
1 teaspoon garlic powder
1/4 teaspoon ground mustard
1/4 teaspoon salt
1 bunch broccolini, largely chopped
1 medium shallot, sliced
8 oz mushrooms, sliced (I used baby bella)
1/4 to 1/2 cup feta cheese crumbles
1/2 cup fresh basil leaves, chopped (or chiffonade)
Preheat your oven to 350 degrees Fahrenheit.
Combine the eggs, milk, parmesan cheese, garlic powder, and mustard in a medium mixing bowl, and whisk together until the egg is fully mixed. Set aside.
In a 10-inch cast iron skillet, heat olive oil on medium-high heat and saute the broccolini, shallot, and mushrooms until softened about 5 to 7 minutes. Turn off the heat and pour the egg mixture evenly over the vegetables in the skillet (see Notes 1 & 3). Top with feta cheese.
Bake in the oven for 20-25 minutes or until evenly cooked. To tell it is done insert a knife into the center until it comes out clean (see Notes 2).
Cut into squares or slices and serve with a salad, roasted potatoes, or a favorite toast!
2. The frittata should be firm and not be runny or able to jiggle in the middle.
3. If you prefer to cook the frittata in a baking dish (as I did above), transfer the sauteed vegetables to the baking dish and pour the egg mixture over it. Top with feta. For a larger baking dish, such as a 9 x 13, your cooking time will be closer to 25-30 minutes.
