Frittata Filling:
Remember, use what you have left over in the fridge, but here’s what I like to use to make a tasty frittata.

2-4 potatoes, medium dice
1 medium sized onion, diced
1 sm bunch Asparagus, cut into bite sized pieces
½ cup Mushrooms, slicedFrittata_ROTM
2 Sausages, cooked and cubed (optional)
½ cup shredded cheese (optional)
Red pepper flakes (optional)

Important Note about Food Safety:
You shouldn’t use veggies that have mold on them or smell foul or bitter. They’ve likely gone bad, and should be added to your compost! For your greens, they’ve gone bad if they’ve turned a yellowish color and/or appear slimy.

Egg mixture

8 eggs : 1/3 cup milk (12 eggs: ½ cup milk or 6 eggs: ¼ cup milk)
Finely chopped herbs (optional)
If you don’t want to use milk make sure to whisk your eggs and beat them up right before pouring in your pan and putting the pan in the oven!

Optional cheeses: manchego, goat cheese, cheddar, mozzarella, etc (leftover nibs and nubs)

How to bake:

Preheat oven 375F

Toss all chopped fillings together (except herbs, cheese) with oil S&P (red pep flakes optional) on a sheet tray and roast for 20-30 minutes tossing every 10 minutes for even cooking. The goal is to cook things until they are done but not over cooked.

  • Alternative ways of cooking filling ingredients:
    • Grill veggies and meats
    • Blanch/boil vegetables (pat/drain dry before adding to eggs)

Grease your pan with cooking spray, butter, oil

Fill pan ⅔ way with filling

Pour egg mixture

Top with cheese (optional, very highly recommended)

Place in a preheated oven at 350F degrees and check every 5-10 minutes. Rotate your pan so eggs cook evenly!

How to know when your frittata/ egg bites are done?

Check on your frittata by using a heat-safe oven mitt or a kitchen towel. If you are using a thermometer the internal temperature should be about 160F. Give the pan a soft shake. If the mixture is loose and jiggles then it needs more time (OR check your eggs by jiggling your pan slightly and if the center is wobbly then it’s not done yet!). You’re looking for the eggs to be just set with a slight wobble in the center.

Pro tip: right before you are finished cooking your eggs, place them under the broiler for 1-2 minutes. This will give the tops of your frittata a nice crust and light browning while making sure to not overcook the center.
