Cheese & Onion Mini Croissant Quiche Recipe

Mini Quiche Header

One of my favourite morning breakfasts is this Cheese & Onion Mini Croissant Quiche recipe that I’m sharing with you today. No one wants to spend a lot of time in the kitchen, especially on the weekend, and this recipe will ensure you’re enjoying your meal more and prepping less!

This recipe will make 12 mini quiches. Any leftovers (if you’re lucky enough to have any left!) are great for warming up when you’re in a hurry during the week.

Another great thing about this recipe is that you’re not obligated to include the cheese and onion that I use here. Mix it up! I’ve made cheese and ham before (my son’s favourite combo) but you can really put anything to fill your cups…. broccoli, bacon, turkey, spinach, leeks, caramelized onions, sun-dried tomatoes. Use your taste buds to guide you and you’ll surely come up with something delicious. 😋

  • Beat together the eggs, milk, salt, pepper and onion powder. Divide equally between the muffin tins. This will not reach the top of the tins and that's okay, they will rise!
