There's nothing quite as versatile as a good impossible quiche.  You can eat it at any time of the day, by itself or with some easy sides.

It stores well in the fridge for a few days and can be frozen for later if you can't eat it all that quickly.  I've purposely kept this crustless quiche bare bones - just ham and cheese.  You can, of course, add in some veggies or mix it up with some bacon.

Or just leave it as is because it tastes absolutely delicious.  This recipe is a great way to use up leftover ham after the holidays, or just when you need an easy dinner you can throw together quickly.

Why you'll love this recipe...

  • Very easy to prepare.
  • Versatile - you can add in veggies or use a different protein.  
  • Great way to use up leftover ham from the holidays.

WHAT IS IMPOSSIBLE QUICHE?

Impossible quiche, also known as a crustless quiche, is a quiche that requires no pastry base.  The reason it doesn't require a base is that a little flour is added to the mixture before baking that separates and sinks to the bottom to form a light crust like magic!

INGREDIENTS YOU'LL NEED

This is such a good dinner to make in a pinch as it's made from everyday ingredients most of us always have on hand!  Here's what you'll need to whip up this impossible quiche (full measurements listed below)...

  • Olive Oil 
  • Brown Onion 
  • Cheddar Cheese
  • Parmesan Cheese
  • Ham
  • Self-Raising Flour - If you don't have self-raising flour simply use a mixture of plain / all purpose flour and baking powder. The conversion is 1 cup of flour to 2 teaspoons of baking powder.
  • Milk
  • Eggs

STEP BY STEP INSTRUCTIONS

Preheat the oven to 200C / 390F and grease a pie tray (9" x 2" / 22.5cm x 3.1cm).

Heat oil in a small frying pan and cook the onion until translucent.

Combine 1 cup shredded cheddar cheese, parmesan cheese, ham, onion, flour, salt and pepper in a bowl, then pour into a pie dish.

Whisk eggs and milk together in a seperate bowl, then pour over the ingredients in the pie dish. Sprinkle the remaining shredded cheddar cheese on top.

Can you make crustless ham and cheese quiche ahead of time and reheat?

Definitely.  Quiche is one of those foods that tastes just as good reheated the next day.  I personally prefer to reheat it in the oven but you can also zap it in the microwave too.

Quiche can be stored in an airtight container in fridge for up to 3 days.

Can you freeze quiche?

Absolutely.  Quiche freezes really well.  Just place it in an airtight container and store in the freezer for up to two months.

What goes with quiche?

You can totally serve quiche on it's own for an easy breakfast or light dinner.  I like to pair it with a simple salad and even some potatoes, especially if I'm feeding a few people.  Here's a few recipes that go well with this quiche:

  • Cabbage and Crunchy Noodle Salad
  • Greek Lemon Potatoes
  • Middle Eastern Bean Salad
  • Crispy Baked Potato Wedges
  • Pumpkin, Spinach & Feta Salad

MORE EGG RECIPES TO TRY

  • Vegetarian Quiche
  • Mini Vegetarian Quiches
  • Bacon and Egg Pie
  • Zucchini and Bacon Slice

TOP TIPS FOR MAKING THIS RECIPE

  • You can simply add the onion into the mixture without frying it first but I always find frying onion brings out more flavour and it's worth the extra washing up!
  • Feel free to add in some veggies to the quiche - some finely diced capsicum / bell peppers or a grated zucchini would go great!
  • You can also try this quiche with bacon instead of ham.  Just fry the onion and bacon together first before adding to the rest of the ingredients.
  • Great served warm or cold.

Peanut Butter Eggs Recipe 🥜🥚🍫 : https://www.cookitrealgood.com/peanut-butter-eggs/

OR comment with "Peanut" and I'll DM you the link!

For me, this Peanut Butter Eggs recipe is a holiday staple—not just for Easter. It’s my ultimate comfort treat that shows up during every festive season, including the run-up to Christmas. I hope that’s not weird 😆😁.

They've got that nostalgic chocolate-peanut butter combo everyone loves, but with a homemade twist that makes them even better. Plus, you can dip and drizzle them in any chocolate you like—dark, white, milk—and decorate them to look just like colourful eggs.

Nutella Brownies

Honestly, I first tried making these on a whim. A friend and I were having a lazy weekend baking session, and we had a jar of chocolate hazelnut spread lying around. We decided to see what happened if we added it to our brownie batter.

Ingredients:

100g brown sugar
50g granulated sugar
2 eggs
2 teaspoons vanilla extract
200g Nutella
¼ teaspoon salt
150g all-purpose flour
2 tablespoons cocoa powder
100g dark chocolate chips

Still recovering from the nightmare of being force-fed stinky and bitter boiled brussels sprouts as a child?  Never fear - these Crispy Brussels Sprouts with Bacon will turn even the most adamant brussels sprouts hater around.

Brussels sprouts really shine when oven roasted - crisp and caramelised on the outside and tender on the inside.  Not to mention how simple it is - throw everything on a tray in the oven for 25 minutes and voila!

Chicken Florentine

If you're craving a comforting, creamy dish, Chicken Florentine is the answer. Imagine golden-fried chicken smothered in a rich, garlic spinach cream sauce. The sauce is silky smooth, with just the right amount of tang from the Parmesan cheese and a burst of flavor from the fresh baby spinach.

2 large boneless skinless chicken breasts
1 teaspoon garlic powder
1 teaspoon salt
1 teaspoon black pepper
1 teaspoon onion powder
3 tablespoons all-purpose flour
3 tablespoons olive oil

For the sauce:

3 tablespoons butter
1 large shallot, minced
2 cloves garlic, minced
1 cup low-sodium chicken broth

1 teaspoon dried basil
1 teaspoon dried oregano
1 teaspoon dried thyme

½ cup grated Parmesan cheese
2 cups fresh baby spinach

Maybe it’s because of the cute color—my kids really love carrots. Especially when they’re roasted with potatoes, the kids go wild for it… well, their dad too, haha. But I’m worried they’ll get bored, so I try to look for different recipe variations where carrots are the main ingredient.

Mexican Chicken Salad Full Recipe 🌯🥗: https://www.cookitrealgood.com/mexican-chicken-salad/

OR comment with "MEXICAN" and I'll DM you the link! 🖐

I love Mexican food, so it's no surprise that one of my favourite salads is Mexican inspired.  This Mexican Chicken Salad is full of good-for-you ingredients and is filling enough to be a complete meal on its own.  The chicken is juicy and bursting with flavour.

It's on the table in 15 minutes.  Yes, you heard right - 15 minutes!  This does require a little multi-tasking, like chopping salad ingredients while waiting for the chicken breast to cook.  But totally doable.

Gigi Hadid Pasta 🫕🍴

Maybe this is the closest I’ll ever get to Gigi Hadid, hahaha. This Gigi Hadid Pasta is actually just a version of the classic Italian-American dish, penne alla vodka. But back during the Covid era, Gigi Hadid shared the recipe on her social media, and ever since then, everyone’s been calling it Gigi Hadid Pasta.

Plus, it's super simple to make with minimum prep time, so even if you're not a pro in the kitchen, you've got this.

Here's what you'll need to make this recipe:

8 ounces or 225 grams of pasta (like penne)
2 tablespoons olive oil
2 cloves garlic, finely minced
1 small shallot, chopped (or red onion)
¼ cup tomato paste
2 tablespoons vodka (optional)
½ cup heavy cream
1 teaspoon chilli flakes (or add red pepper flakes)
½ teaspoon salt
½ teaspoon black pepper
¼ cup Parmesan cheese, freshly grated
1 tablespoon butter
A handful of fresh basil for garnish

Hey Mercy, you can absolutely make this with chicken instead. I'd recommend using shredded chicken but other than that all will be the same.
Hola Mercy, puedes hacer esto con pollo. Recomiendo usar pollo desmenuzado, pero aparte de eso, todo será igual.

Your recipe (with a slight name change) reminds me of the same recipe. I've made for my young family in the 1980's. it was all the rage and very popular with my friends. We called it an Impossible Pie. We loved it made with tuna as well. Was great in school lunches.

Me, too. Years ago, early 80's, had a few little cookbooks that had "Impossible" pies. Everything was delicious. Very few ingredients, mostly in everyone's kitchen. And eggs were very cheap.

I have a question,
I made this quiche a couple weeks ago and it was really good for my first time making quiche. My question is if I use a pie crust can I delete the flour out of the ingredients? Does anything else need to be changed for the quiche to turn out?

Cassie

Cassie

April 12, 2020

Hey Lyndon, just be sure to blind bake the pie crust before baking the quiche but yes, just omitting the flour should be fine 🙂

This recipe is so easy and DELICIOUS. Combine this dish with a salad and you have a complete meal. I didn’t have Parmesan Cheese on hand so I substituted Mozzarella Cheese. I also had some Baby Bella Mushrooms that I wanted to use before they spoiled. I chopped the mushrooms up and combined them with onions and sautéed them together. The leftovers heated nicely in the microwave. My husband asked if we could have this recipe again.

Cassie

Cassie

I am so happy to hear that Bev! Love your substitutions too. I made it up last week with some mushrooms and capsicum / bell pepper I needed to use up too and it was good. Might do that every time from now on - can never have too many veggies can we!

Could you cook this in the air fryer?

Cassie

Cassie

February 18, 2020

Hey Richenda, you absolutely could. The only problem you might have is fitting the tin in your air fryer depending how big your air fryer is. I have seen people turn these into mini quiches in muffin pans so that could work!

Yep - it might add a slightly nutty flavour but if you are a regular almond milk drinker it shouldn't be an issue 🙂
