Mastering Quinoa Chard Frittata with Balsamic Onions: How-To

Step 1: Cook the Quinoa
Start by rinsing the quinoa under cold water. In a medium saucepan, combine the quinoa, vegetable broth, and a pinch of salt. Bring it to a boil, then reduce the heat to low, cover, and let it simmer for about 15 minutes or until the quinoa is fluffy and the liquid is absorbed. Set it aside to cool slightly.
Step 2: Sauté the Onions
In a large frying pan or cast-iron skillet, heat the olive oil over medium heat. Slice the yellow onion thinly and add it to the pan. Sauté for about 5 minutes until the onions become translucent.
Step 3: Add Balsamic Vinegar
Pour in the balsamic vinegar and a pinch of sea salt. Continue to cook the onions for another 5-7 minutes, allowing them to caramelize and develop a deep, rich flavor. Stir occasionally to prevent sticking.
Step 4: Prepare the Chard
While the onions are cooking, wash and shred the chard leaves. Once the onions are caramelized, add the chard to the pan and cook for about 3-4 minutes until wilted.
Step 5: Whisk the Eggs
In a mixing bowl, whisk together the eggs, heavy cream, salt, and black pepper until well combined.
Step 6: Combine Ingredients
Add the cooked quinoa to the pan with the chard and onions. Pour the egg mixture over the top, ensuring everything is evenly distributed.
Step 7: Cook the Frittata
Reduce the heat to low and let the frittata cook for about 10-12 minutes, or until the edges are set but the center is still slightly jiggly. You can cover the pan with a lid to help it cook evenly.
Step 8: Broil for Perfection
Preheat your broiler. Once the frittata is almost set, place the skillet under the broiler for 2-3 minutes, just until the top is golden and puffed. Keep a close eye to avoid burning.
Step 9: Serve and Enjoy
Remove the skillet from the oven and let the frittata cool for a few minutes. Slice into wedges and serve warm or at room temperature.
Vegan & Vegetarian Swaps

If you’re looking to make this dish vegan or vegetarian, here are some easy substitutions:
- Replace the eggs with a mixture of 1/4 cup chickpea flour and 1/4 cup water for each egg.
- Use coconut cream instead of heavy cream for a dairy-free option.
- For a vegetarian twist, consider adding cheese such as feta or goat cheese for an extra layer of flavor.
These swaps maintain the integrity of the dish while catering to various dietary preferences.
Problems & Prevention
When preparing your Quinoa Chard Frittata with Balsamic Onions, consider these tips to ensure a successful outcome:
- Overcooking: Keep an eye on the frittata while broiling to prevent burning.
- Texture: If using too much cream, the frittata may become overly rich. Stick to the recommended amount.
- Ingredient Substitutions: Ensure that vegetables are well-cooked to avoid excess moisture, which could lead to a soggy frittata.
By being mindful of these factors, your frittata will turn out perfectly every time.
Keep-It-Fresh Plan
To keep your Quinoa Chard Frittata fresh and delicious:
- Store any leftovers in an airtight container in the refrigerator for up to 3 days.
- Reheat slices in the microwave or in a skillet over low heat, adding a splash of water to keep it moist.
- For longer storage, consider freezing individual slices wrapped in plastic wrap and then in foil for up to a month.
This ensures that you can enjoy this flavorful dish even on your busiest days.
Quick Questions
