FAQs & Tips

What is a frittata?

A frittata is an Italian egg dish that’s similar to a crustless quiche. It’s usually made by mixing eggs with cooked meat, vegetables,  and cheese. Everything is cooked over low heat until the eggs are set.

What vegetables should you use?

As with most fritattas, you can get creative with this recipe. Frittatas work best when you use your favorite vegetables. What you see in the pics is a combination of chopped spinach, cherry tomatoes, and red onion. Other suggestions include mushrooms, bell peppers, or even zucchini. 

What type of milk should you use?

Use the milk of your choice! Regular milk, oat milk, nut milk, etc. all work well in this recipe. 

What type of cheese should you use?

Use your favorite cheese! There is no right or wrong answer. The original cookbook recipe uses shredded cheddar cheese which is what you see here. Other suggestions include shredded mozzarella or even grated Parmesan. 

When do you serve this?

What I love most about a frittata is that It’s versatile, easy to make, and works well for breakfast, lunch, or even dinner. Plus, it’s a great way to use up leftover ingredients you already have on hand.

A modified version of this recipe appears in my cookbook, The Low Sodium Slow Cooker Cookbook.
