Isn’t this GORGEOUS? Super healthy and low-carb (especially since I opted to make this a crustless quiche recipe) with so much color and flavor!

Spinach is a hot favorite with The Husband, in pretty much all forms: fresh, frozen, or canned. I’ve heard tales of him as a kid opening cans of spinach and devouring them after school, Popeye style. Lol.

Love low carb? You’ll enjoy this low carb chicken dinner – all made in one skillet, or this Sheet Pan Chicken Dinner – so good (and low on clean up too!)

In my house, spinach is pretty much always on the grocery list, and I include it in as many things as I can. (I’ve been known to cook and puree spinach, and add a cup to our spaghetti sauce and giggle as my children chow down on it happily – if you tell them, I will deny it, and never bake you cookies. Ever!)

Eating at home means lots of family time around the dinner table, and teaching the kids how to prepare meals. H can wash spinach, drain and rinse canned beans, crack eggs into bowls, mix ingredients, and… licking the beaters whenever I bake.

He’s not so excellent at dish-washing, or table clearing. But we’re working on it! I’ve found that the more involved I allow the kids to be, the more willing they are to try different things, and eat whatever we make because they’re so proud to have “made it”.

So. How about this spinach quiche then? It’s super easy and takes just 25 minutes in the oven til it’s ready to serve (about 45 minutes total).

Anywayyyyy… look at these simple and yummy ingredients. These are all you need to make my crustless quiche! (you’re so welcome)

Why this recipe works:

• Simple. Quality ingredients make amazing food.
• Make-Ahead. Make this on a weekend, and eat slices for lunch each day.
• Low Carb (if you’re into that)

Equipment needed

I use a metal tart tin with a removable base, to allow me to remove it from the pie pan more easily, but I have also had good luck with regular glass or ceramic pie pans. Just be sure to grease it well so you don’t get your quiche stuck!

You’ll need a good whisk, a skillet and mixing bowl. That’s it!

• ONION – a medium sized onion will get you about 1/2 cup
• SPINACH – baby spinach leaves. You can add spinach leaves whole, or chop them up a little.
• EGGS
• FLOUR
• BAKING POWDER
• MILK – you can switch this out for heavy cream, or half and half if you are keto!
• FETA – adds a delicious saltiness to the dish
• TOMATOES – grape or cherry tomatoes, or chopped roma tomates all work well
• BASIL – optional, but pairs very well with the tomatoes!

How to make this recipe:

• Preheat oven to 400F.
• Lightly grease a 10-inch quiche or tart pan (or a deep dish pie plate)
• Heat the olive oil in a skillet over medium heat, and saute the onion until softened.
• Add in the spinach and cook until just wilted (you may need to do this in batches if your skillet is too small). Season with salt and pepper to taste. Set aside to cool 5 minutes.
• In a large mixing bowl, whisk together eggs, flour, and baking powder. Whisk in milk, then stir in the spinach mixture. Add pepper, mix well.
• Pour egg mixture into quiche pan. Top with feta.
• Place the tomato halves on top, and press gently so only the surface is visible.
• Bake for 25-30 minutes, or until center is set and the edge is golden brown – and pulling away from the pan.
• Cool for 10 minutes.
• Garnish with extra feta, and some basil (optional).
• Slice, and serve.
