I originally started making them as a healthier alternative to pastry-based quiches, but they’ve become much more than that. They are ideal for packed lunches, picnics, meal prep and even quick breakfasts when I’m in a rush.
The combination of sweet caramelised red onion and fragrant rosemary makes them feel a little more special than a standard egg muffin, but they’re still incredibly easy to make.

Are Mini Quiches Good For Weight Loss?
Mini quiches can be a great option if you’re trying to lose weight because they are naturally high in protein and easy to portion.
Unlike traditional quiche, which often contains pastry and cream, these mini quiches focus on protein-rich ingredients such as eggs while still providing plenty of flavour.
I find they are particularly useful when I know I have a busy week ahead. Having a couple of mini quiches ready in the fridge means I’m less tempted to reach for convenience foods or skip meals altogether.
As with any recipe, the nutritional value depends on the ingredients used, but they can easily fit into a balanced healthy eating plan.
Snacking tips
There are so many tasty snacks you can make if you are trying to eat healthily. It means you don’t have to get bored with one thing and can vary your diet considerably. These mini crustless quiches are one of my favourites when I follow the Slimming World plan or am generally trying to eat more healthily. I am sure you will also want to eat more and more of them I am sure!
Do you enjoy snacks when really you are not hungry and instead are boredom or comfort eating? I do this a lot so this is why it is so important to find low-calorie snacks when you can.

High Protein Mini Quiches
One of the reasons these mini quiches are so satisfying is their protein content.
Protein helps keep you feeling fuller for longer, making these a great snack or light meal. If you want to increase the protein even further, you could add:
- Cottage cheese
- Reduced-fat cheddar
- Lean ham
- Chicken pieces
- Smoked salmon
They are a much more filling option than many packaged snacks and can help bridge the gap between meals without reaching for biscuits or crisps.
Can You Freeze Mini Quiches?
Yes, these mini quiches freeze really well.
Allow them to cool completely before placing them in an airtight container or freezer bag. They can usually be frozen for up to three months.
To reheat, simply defrost overnight in the fridge and warm through in the oven, air fryer or microwave.
This makes them perfect for batch cooking and meal preparation. I often make a double batch and freeze some for later because they are just as useful for quick lunches as they are for snacks.
What To Serve With Mini Quiches
These mini quiches are incredibly versatile and can be enjoyed in lots of different ways.
Some of my favourite serving ideas include:
- A mixed salad for lunch
- Homemade coleslaw
- Roasted vegetables
- A bowl of soup
- Potato wedges
- Fresh fruit for a picnic
- Couscous salad
They also work brilliantly as part of a buffet spread or picnic hamper.

Rosemary and Caramelised Onion Mini Crustless Quiches
Delicious mini quiches, perfect for a meal or snack for all the family.
- Total Time: 40 minutes
- Yield: 30 quiches 1x
Ingredients
12 large eggs
2 x 250g tubs of fat free cottage cheese with chives or onion and chives (I use the Aldi one as its cheap!)

Instructions
1. Fry the onions in the cooking spray with the sweetener until starting to soften, then add the rosemary and cook until onions are soft.
2. Mix in with the beaten eggs and cottage cheese and then spoon into silicone baking cases or similar. A ladle can make this easier or even pouring the mixture from a jug! I use silicone cases as they don’t stick and therefore makes it easy!

They are lovely hot or cold and can be kept in the fridge for a few days with no problems.
