Tired of the same old breakfast routine? This egg white frittata is a simple yet flavorful way to change things up. Packed with fresh vegetables and savory cheese, it’s a light but satisfying dish that’s perfect for kicking off your day. Plus, it’s keto-friendly and low-carb, making it a guilt-free option if that’s your thing.

Why Egg Whites?
Egg whites are the unsung heroes of the breakfast table. They provide all the protein without the fat and cholesterol found in the yolks. This makes egg whites a great option if you’re looking for a leaner breakfast. Plus, they create a fluffy, tender texture that works beautifully in a frittata.
The Secret Ingredient: Ricotta Cheese
What sets this frittata apart is the addition of ricotta cheese. Unlike other cheeses that melt into the dish, ricotta stays creamy, creating little pockets of richness throughout the frittata. Combined with sharp cheddar, this duo gives a wonderful balance of creamy and tangy flavors in every bite.

Not Just for Breakfast
Who says frittatas are only for breakfast? This dish is so versatile, it can easily find its place at any meal of the day. For a light and refreshing lunch, serve it with a simple side salad of mixed greens, lightly dressed with lemon vinaigrette. If you’re craving something heartier for dinner, pair the frittata with roasted vegetables or a grain like quinoa for a balanced and satisfying meal.
The best part? It’s also a great option for entertaining. Slice the frittata into bite-sized portions, and you’ve got a healthy appetizer that’s sure to impress guests. Whether it’s served warm or at room temperature, this dish offers flexibility and flavor no matter the occasion.
Substitutions and Variations
Looking to switch things up or tailor this frittata to your preferences? Here are a few simple substitutions and variations:
- Different Cheeses: If ricotta and cheddar aren’t your favorites, you can swap them for feta, goat cheese, or mozzarella. Each one brings its own unique flavor.
- Vegetable Add-ins: Not a fan of spinach or cherry tomatoes? Try using bell peppers, mushrooms, or zucchini for a different texture and flavor profile.
- Whole Eggs Instead of Egg Whites: If you prefer whole eggs, you can replace the liquid egg whites with regular eggs. Keep in mind that it will increase the calorie count slightly but also add a richer flavor.
