Tips for Making the BEST Keto Frittata

Although you do not need to follow this recipe to a tee, there are a couple of key factors to think about when trying to create the best keto frittata.

Add-ins - You will always want to keep your ratios pretty consistent to ensure the best keto frittata. Keep your mix-ins (veggies, meat, etc.) to around 2 cups, your eggs around 6-8, your milk at about ¼ cup to ⅓ cup and you will only want to add about ¾ cups of cheese to the mixture. Using salt, pepper and red pepper flakes are all you really need to do to season the frittata.

Pre-Cook Veggies - It’s vital to cook your vegetables and/or meat first, and make sure they aren’t soggy. For this recipe, you are going to sauté the mushrooms and shallot until soft and most of the water has been removed. If your veggies seem a bit wet after cooking, give them a pat down to ensure they’re dry before adding your egg mixture. Also, when you pour the eggs over your cooked veggies, make sure to give the whole thing a quick stir or shake to help distribute them all evenly.

Pick the right pan - Using a hot cast iron or any heavy, oven-proof skillet is really all you need to achieve it. Once you're done cooking the add-ins, pour your eggs into the still-hot skillet, transfer to the oven, and let it do its magic. Same goes if you're starting with leftovers—just get the pan nice and hot and add a little oil or butter to ensure nothing sticks

Keto Frittata Ingredients

• Eggs - You will need 6-8 eggs for this recipe. If you are using a 10-inch pan, use 6 large eggs and if you are using a 12-inch skillet, use 8 eggs.
• Cheese - I used mozzarella cheese in this recipe but feel free to use any cheese you want. I do HIGHLY suggest grating your own cheese since pre-shredded cheese does not melt as well and will not produce the same creamy texture.
• Sausage - I used Amylu Paleo sausage links but you can use any sausage links and slice them or use crumbled sausage instead. You can also omit this ingredient for a plant-based keto frittata.
• Milk - I used unsweetened almond milk but any milk, cream or milk-alternative will work.
• Oil - The oil is used to cook the vegetables. I love extra-virgin olive oil in this reicpe.
• Veggies - For this recipe, I decided to use baby bella mushrooms, spinach and onions that are cooked before hand to ensure that some of the moisture is removed from the veggies. Do not put raw vegetables into a frittatas as the frittata will not set properly.
• Seasoning - Salt, pepper, red pepper flakes and garlic come together for the perfect spice mix.
• Sour Cream - This ingredient is optional but adds an extra level of creaminess to this keto frittata
