Let me show you how you can make easy frittata vegetarian in a few simple steps.
To make a fluffy, custardy spinach and egg frittata, you first need to stir-fry the vegetables in olive oil. This not only adds flavor but also removes any vegetable juice from the spinach and mushrooms that could make your frittata runny.
First, set up all your ingredients on the kitchen countertop. You will need:
First prepare the egg mixture for your spinach and feta frittata.
In a large bowl, whisk all the egg batter ingredients until well combined. Don’t over whisk; just whisk as for an omelette batter. Set aside while you are preparing the vegetables for your spinach mushroom frittata keto recipe.

Next, heat olive oil over medium in a large non-stick saucepan or cast-iron skillet. I really mean large pan because fresh spinach needs a lot of room even if it shrinks down when cooked.
Start by sautéing onions and garlic, then stir fry the sliced button mushrooms and diced red bell pepper if used. If you don’t like red bell pepper, simply remove it from the recipe.
Stir fry the vegetables for 2 minutes until mushrooms release their juice and season with salt and pepper. Next, add the baby spinach and cook with a lid on the pan. This will help the spinach shrink down and cook fast. Remove lid every 30 seconds, give a good stir and keep cooking until the spinach is wilted and the roasted vegetables released their juices.
Transfer the cooked vegetables using a slotted spoon onto a 10-inch round baking dish or a 9-inch x 9-inch square baking dish. The slotted spoon drains the vegetables from their juice and prevents a runny frittata.
Next, pour the egg mixture on top of the vegetable. Finally, sprinkle the shredded cheddar evenly over the dish. To make a mushroom and spinach frittata with goat cheese, as seen in my picture, crumble goat cheese all over the pan.
Goat cheese is a keto-friendly cheese, and it adds the most delicious creamy texture and flavor to your spinach mushroom frittata recipe.
The best part about this keto spinach mushroom frittata recipe is:
Keep in mind that if you use a microwave, it makes the frittata texture very chewy and runny, especially if it had been frozen before.
So, I highly recommend you rewarm leftovers in the oven.
You can use frozen spinach to make this keto frittata spinach recipe. Obviously, they will release a lot of liquid in the pan, and you will have to cook the vegetable a little bit longer to evaporate the extra liquid.
Another option is to thaw the frozen spinach for a few hours before preparing this spinach feta frittata keto recipe.
Mushrooms are great keto low-carb vegetables packed with protein. However, if you don’t like mushrooms and don’t mind adding meat to this recipe, replace it with the same amount of bacon pieces. A spinach and bacon frittata taste amazing, too, with goat cheese on top.
This frittata is even better served with a dollop of sour cream on top. It adds a tangy, fresh, and creamy touch to the dish.
