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, pretty, and nutritious. I make it often when we host for brunch, but I also like to make it for my family for dinner.
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. Butter works too.
Vegetables and herbs: Onion, fresh baby spinach leaves, minced garlic, dried thyme, and red pepper flakes.
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. 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.
5. Bake the frittata until golden brown and puffy, 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 great with a simple side of arugula salad or tomato salad.
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 these leftovers so much, that sometimes I intentionally double the recipe and bake two frittatas, to ensure I have yummy leftovers for my breakfast!
