Step‑by‑Step Instructions for Baked Egg White Frittata
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This will ensure that your Baked Egg White Frittata bakes evenly and achieves a lovely golden top. While the oven warms up, you can prepare your sautéed vegetables, as everything will come together smoothly for a quick and delightful breakfast treat.
Step 2: Prepare the Pan
Heat 1 tablespoon of olive oil in an 8-inch nonstick frying pan over medium heat. Allow the oil to warm for about 1-2 minutes until it’s fragrant but not smoking. This will create a non-stick surface for the frittata and enhance the flavor as the vegetables cook.
Step 3: Sauté the Bell Peppers
Add your diced bell pepper to the pan, stirring frequently for 4-5 minutes until the peppers are tender and vibrant. This step adds a burst of color and sweetness to your frittata. Keep an eye on them to ensure they don’t burn; you want them soft and aromatic.
Step 4: Add the Spinach
Toss in the fresh spinach and allow it to wilt, which should take about 2 minutes. You’ll know it’s ready when the spinach is wilted and bright green, infusing your Baked Egg White Frittata with nutrients and a fresh, earthy flavor. Stir it in gently to combine with the bell peppers.
Step 5: Incorporate Tomatoes
Now, add the halved cherry or grape tomatoes to the pan and sauté for an additional 1-2 minutes. The tomatoes will soften and release their juices, creating moisture and sweetness that balance the flavors in your frittata. Stir occasionally, letting the mixture marry as it cooks.
Step 6: Whisk the Egg Whites
In a separate bowl, whisk your egg whites until they become frothy, which should take about 1-2 minutes. As you whisk, add black pepper and garlic powder for flavor. This step is crucial for achieving that light, airy texture in your Baked Egg White Frittata that everyone loves.
Step 7: Combine and Bake
Pour the frothy egg whites over the sautéed vegetables in the pan, ensuring they’re evenly distributed. Next, sprinkle shredded cheddar cheese on top for a creamy richness. Carefully transfer the pan to your preheated oven and bake for 16-20 minutes, or until the frittata is set and the cheese is bubbly and golden.
Step 8: Cool and Serve
Once baked, remove the frittata from the oven and let it cool for a few minutes. Slice into wedges, and serve warm. For an extra touch, top with sliced avocado and green onions to enhance the flavor and presentation of your delicious Baked Egg White Frittata.

Expert Tips for Baked Egg White Frittata
Use Fresh Ingredients: Always opt for fresh vegetables to ensure your Baked Egg White Frittata is bursting with flavor and nutrients.
Non-Stick Pan: Utilize a non-stick, oven-safe skillet for best results; this will prevent sticking and ensure easy serving. Avoid cast-iron skillets, as they may not yield the same texture.
Serve Immediately: For the fluffiest frittata, serve it straight from the oven. Egg whites tend to deflate over time, losing that light and airy quality you love.
Cooking Time Adjustments: If using a larger skillet, check for doneness sooner, as this can affect cooking time due to a thinner batter.
Store Leftovers Properly: Keep leftover slices in an airtight container in the refrigerator for up to 2 days. Reheat gently to maintain texture and flavor.

What should I do if my frittata doesn’t rise properly?
If your frittata doesn’t rise and appears dense, there could be a couple of reasons. Make sure to whisk the egg whites until they’re frothy, as this incorporates air, helping it puff.
