spinach mushroom and bacon frittata ingredients

In the past, frittatas always intimidated me. I do not know why but for the longest time I stuck with my classic soft scrambled eggs, omelettes and egg cups. Although, now that I think about it, the egg cups were essentially the same as the frittata… just as cups. But, I do have to say, there is something about cooking in a cast iron skillet that gives this spinach mushroom and bacon frittata that extra texture boost around the edges. The crispy edges give the frittata a nice base and wall of support for the fabulous mixture of eggs, vegetables, bacon and spices.

I use a Lodge Cast Iron Skillet and have a few different sizes in this brand as well. The quality of this brand itself is unparalleled and most definitely worth the money! Find it: here

What’s the difference between a quiche and a frittata?

This is such a common question! While they look extremely similar and have very similar ingredients, there is one distinct difference: the crust! A quiche has a crust, typically a pie crust of some sort but recently many cooks have begun to make the crusts out of sweet potatoes too. Frittatas on the other hand are crustless, allowing the egg mixture to get that crispy outside texture. This is why I believe that a cast iron skillet is an essential component to this recipe. While is it not necessary, the cast iron skillet gives that super delicious and crispy outside to the frittata. Additionally, quiches typically have a creamier consistency while frittatas have a more classic omelette consistency. This is due to the amount of milk/cream added to the egg mixture.

How to reheat the frittata:

Another great question here, as this is a perfect breakfast to prep for the week or take as leftovers! For the microwave option, simply reheat for 1 and a half minutes in three 30 second increments. Make sure you are using an oven safe dish such as these Glass Meal Prep Containers. This recipe keeps in the fridge for 4-5 days and in the freezer for up to 6 months in a well-sealed container.

Can I make any substitutions or add more ingredients?

Meat: you can leave out the bacon completely for a vegetarian or pescatarian version of this recipe. You can also substitute any meat of choice, as long as it is chopped up like the bacon would have been.
Vegetables: feel free to substitute with any vegetables that you may have on hand as long as you keep the amount of vegetables the same. This recipe calls for 1 1/4 cups of firm vegetables and 1 cup of leafy greens. So for example, you could substitute white or yellow onion for red onion. For the spinach, you can opt out completely or substitute kale or arugula. Another way to look at this is to make it more seasonally inspired, depending on when you are making this recipe. Currently spinach, mushrooms and bell peppers are the in season vegetables I chose, but shaved brussel sprouts, tomatoes, or broccoli would be fabulous as well.
Add cheese! A delicious salty component. I think that feta, cheddar or mozzarella would work great in this recipe. I would stick to 1/2-3/4 cup.
