Ingredients and Substitutions
Zucchini and peas - any combination of vegetables will work in this recipe. You will need a total of approximately 4 cups of chopped vegetables. Asparagus, green beans, mushrooms, bell peppers, cooked broccoli or cauliflower are just some examples of vegetables that can be used.
Spinach is my go-to for adding greens to a frittata but other greens that work equally well are arugula, kale, Swiss chard and collard greens. If using kale, chard or collards, add them to the pan with the zucchini so they have time to cook. You can also steam or sauté them ahead of time.
Leeks can be replaced with one large diced white, yellow or Spanish onion.
Feta cheese - I love feta for it's salty, briny punch it adds but a great substitution would be small pieces of goat's cheese.
Cheddar and smoked cheddar cheese are great for their creamy melting qualities and also flavour. Substitute any cheese for what you have on hand. Frittatas are a great way to use up small pieces of cheese leftover in the fridge.
Fresh dill can be substituted with any delicate fresh herbs you like such as parsley, cilantro, basil or a combination. Use up any extra fresh dill with this Chopped Dill Pickle Salad Recipe.
Plain Greek yogurt can be substituted 1:1 with sour cream, cottage cheese or cream.

Recipe FAQs
A quiche has a crust made of flaky pastry dough and a frittata is crustless. Quiche typically has a richer, creamier filling using heavy cream. Quiche is a French dish and frittata is from Italy.
If you don't have an oven-proof skillet you can prepare all the vegetables then transfer them to a greased 9 by 13-inch greased casserole dish. Distribute the vegetables evenly then pour in the egg mixture over top.
Adding dairy with fat is key to creating a light and fluffy frittata. Greek yogurt, sour cream, crème fraiche, cottage cheese, whole milk, or cream all work well to create a fluffy texture. Also be sure to whip the eggs and dairy well with a whisk to incorporate air to the mixture.
Cast iron skillets are perfect for making frittata. A well seasoned cast iron skillet is non-stick and with it's even distribution of heat and heat retention the frittata will bake evenly. However any non-stick and oven safe skillet will work.
Expert Tips
Non-stick pan: It's important to use a non-stick pan when making frittata. If transferring to a casserole dish grease with butter or spray with non-stick spray before adding the frittata mixture.
Let rest before slicing: Letting the frittata cool and set for a few minutes before slicing makes it easier to slice.
Don't overbake: Keep an eye on the frittata and remove from oven when it has just set. Oven temperatures vary so timing may need to be adjusted for your oven. Check after 20 minutes. Gently shake the pan and look for any liquid moving in the center. You can also press the center with your finger to see if it is firm.

So yummy! Will definitely be making this one again. Only had orange cheddar but worked out ok. I feel like it didn’t even need the cheddar with the feta in there. A winner!

Christine Peets says
This was definitely the BEST Frittata! As I can't digest cow's milk, I substituted goat milk cheddar and (sheep milk) peccorino cheese and then added goat milk feta. It was delicious. Surprisingly, there were leftovers, which made a wonderful savoury breakfast. I made half the recipe for the two of us. Next time, I will make the full recipe and either invite company or freeze the leftovers.
Thank you Andrea!
