Wonderfully flavorful spinach frittata is the ultimate brunch dish to make when you have company. It also makes a great meatless dinner.
I really like frittatas. I like egg dishes in general for breakfast – I find them very satiating – and frittatas are especially easy to make. Plus, leftovers keep well for several days.
This spinach frittata is delicious, substantial, and very pretty. I make it often when we host for brunch, but I also like to make it for my family for dinner. It’s definitely substantial enough to serve as a main course.
The ingredients you’ll need
You’ll only need a few simple ingredients to make this tasty frittata. The exact measurements are listed in the recipe card below. Here’s an overview of what you’ll need:
Eggs: I use large eggs in almost all of my recipes, this one included.
Kosher salt and black pepper: If using fine salt, you should reduce the amount you use, or the frittata could end up too salty.
Grated Parmesan: Make sure you use finely grated parmesan and not coarsely shredded.
Olive oil: I love cooking with this delicious oil. But if you’d rather use an oil with a higher smoke point, you can use avocado oil instead. Another tasty alternative is to use butter.
Vegetables and herbs: I use onion, fresh baby spinach leaves, minced garlic, dried thyme (double-check to make sure it’s fresh), and red pepper flakes. The red pepper flakes don’t make the frittata spicy – they merely add an interesting layer of flavor. However, you can omit them if you wish.
How to make a spinach frittata
It’s easy! Scroll down to the recipe card for the detailed instructions. Here are the basic steps:
1. Whisk together the eggs, salt, pepper, and Parmesan.
2. Cook the onion in olive oil or in butter. Add the spinach, a handful at a time, then add the garlic, thyme, and red pepper flakes.
3. Remove from heat and stir the onion/spinach mixture into the egg mixture.
4. Transfer the mixture to a greased preheated pie plate (I place it in the oven and allow it to preheat with the oven).
5. Bake the frittata until golden brown and puffy. This should take about 30 minutes in a 400°F oven.
How to serve spinach frittata
I love serving it for brunch. It’s tasty, filling, and it’s a great keto and low-carb option. So even if I serve high-carb items, I know that anyone of my guests who prefers to eat low carb will have something good to eat!
When you have people over, frittatas make your life as a hostess so much easier, because you can make them in advance and reheat. Or you can even serve them at room temperature.
Sometimes I make this tasty frittata for my family and serve it as a meatless dinner. It’s very filling, and it’s great with a simple side of arugula salad or tomato salad. So that’s a truly easy dinner that the entire family enjoys.
What about leftovers?
Leftovers keep well in the fridge, in an airtight container, for up to 4 days. Reheat them in the microwave on 50% power, or enjoy them cold.
In fact, I like the leftovers of this spinach frittata so much, that sometimes I intentionally double the recipe and bake two frittatas, to ensure I have yummy leftovers for my breakfast the entire week! I also like to grab a slice as a snack – I eat them cold, straight out of the fridge.
