Step-by-Step Instructions for Rainbow Frittata
Making a rainbow frittata is as simple as whisk, sauté, and bake. Let’s go through the easy steps to pull it all together:
- Preheat and Prep:
Preheat your oven to 375°F (190°C). Lightly grease a 10-inch oven-safe skillet or baking dish with olive oil or cooking spray.
- Sauté Veggies:
Heat a small splash of olive oil in a skillet over medium heat.. Toss in the red onion, bell peppers, and zucchini. Sauté for 4–5 minutes until softened. Add the spinach and sauté for about a minute, until it wilts. Remove from heat.
- Whisk Eggs:
In a bowl, mix the eggs with milk, a sprinkle of salt and pepper, and whichever herbs you like best. Fold in the shredded cheese.
- Combine and Bake:
Gently pour the egg mixture over the sautéed veggies, spreading it out in an even layer. Top with halved cherry tomatoes.
- Bake:
Transfer the skillet to the oven and bake for 18–22 minutes, or until the center is set and the edges are lightly golden. It’s ready once a knife or toothpick stuck into the middle pulls out clean.
- Cool and Serve:
Warm a splash of olive oil in a skillet over medium heat, then add the red onion, bell peppers, and zucchini. Serve warm or at room temperature.
Ready in under 30 minutes, this dish is ideal for busy mornings or a relaxed weekend brunch. Now, let’s take it to the next level with some clever tweaks and tips.
