Chef’s Notes – Caramelized Onion and Swiss Chard Frittata

• Preparation Tip: Preheat the oven to the correct temperature before starting to ensure even cooking and to prevent the frittata from sticking to the pan.
• Egg Mixture: Whip the eggs and egg whites thoroughly for a fluffy texture. The addition of Swiss cheese not only adds flavor but also enhances the frittata’s creaminess.
• Ingredient Substitutions: For a dairy-free version, use dairy-free cheese. You can also substitute Swiss chard with spinach if you prefer a milder taste.
• Caramelizing Onions: Cook onions over low heat first to soften them and then increase the heat to caramelize. This two-step process enhances their sweetness and depth of flavor.
• Swiss Chard Preparation: Ensure Swiss chard is cleaned properly. Separate the stems from the leaves to allow even cooking since the stems take longer to soften.
• Skillet Cooking: Use a non-stick or well-seasoned cast-iron skillet to prevent sticking. Stir the egg mixture gently to combine with the vegetables without scrambling.
• Baking Tip: Keep an eye on the frittata in the oven. It should be just set and slightly puffed. Overcooking can make it dry.
• Resting Time: Let the frittata rest for a few minutes before cutting to allow it to set completely and make slicing easier.

Unveil the world of healthy, delightful breakfast options with this Caramelized Onion and Swiss Chard Frittata. Quick and nutritiously packed, this recipe makes mornings exciting!

Ingredients

• 4 large eggs

• 4 large egg whites

• 1/4 cup grated Swiss cheese

• 1/2 bunch Swiss chard about 6 1/2 cups, washed and prepared

• 1 large white onion thinly sliced

• 2 tsp whipped butter

• Kosher salt and fresh ground black pepper to taste

• Alternative Ingredients

• Dairy-free cheese instead of Swiss cheese

• Spinach in place of Swiss chard for a milder taste

Directions

• Oven Preparation – Preheat the oven to 400°F. It’s crucial to ensure the oven is at the right temperature before baking for even cooking.
• Egg Mixture Preparation – Whip the eggs, egg whites, Swiss cheese, and a dash of salt and pepper in a mixing bowl. This mixture will be the base of your frittata, providing structure and flavor. Allow the ingredients to fully integrate by whipping for about 2 minutes.
• Chard Preparation – Clean and separate the Swiss chard leaves from the stems. Chop the stems finely and cut the leaves into broad strips. This adds texture and ensures even cooking.
• Onion Cooking – Melt half the butter in a skillet over low heat. Add the sliced onions, sprinkle with salt and pepper. Let the onions cook slowly until they are soft and translucent, about 8-10 minutes, then turn up the heat to caramelize them, which takes about 5 more minutes.
• Chard Cooking – Add the remaining butter to the skillet, then put in the chard stems. After about 3 minutes, when the stems soften, add the chard leaves. Cook until the leaves are wilted but still vibrant, about 3 minutes. Season accordingly.
• Frittata Assembly – Reduce the heat to low, and pour the egg mixture over the cooked onions and chard in the skillet. Stir gently to combine. Let cook until the edges begin to set, about 7 minutes. Then, transfer the skillet to the oven to finish baking, around 5 minutes.
• Serve – Take the skillet out of the oven, let it rest for a few minutes. Cut the frittata into wedges and serve directly from the skillet or transfer to a serving plate.
