Ingredient Overview:

As always, the full ingredient list & directions is in the recipe card at the end of this post.

• Puff Pastry – Find this in the freezer section at most grocery stores. Thaw according to package directions (or overnight in the fridge – my preference!).
• Spinach – Use fresh spinach. If using frozen, you’ll want to thaw it and squeeze the liquid out. See other veggie options in the variations section at the end of this post.
• Bacon – Ham or sausage work too! Be sure to cook your meat first – don’t add any raw meat into the filling.
• Milk – I used 2%. Whole or skim work fine too. Use what you have on hand!
• Heavy cream – Half and half works too, or all milk in a pinch.
• Eggs – I used large ones.

Ingredient Substitutions:

• Gluten-free – It’s likely going to be a bit easier to find gluten-free ready-made pie dough or a gluten-free pie dough mix. But, use gluten-free puff pastry if you can find it! You can also make these crustless mini quiches – be sure to grease your pan well.
• Dairy-free – Use your favorite dairy-free products to make this recipe dairy-free.
• Vegetarian – Omit the meat to make these vegetarian!
• More Variations – See notes on other add-ins in the variations area at the end of this post.

How to Make this Quiche Recipe Step-by-Step:

Step 1: Make the Quiche Filling. First, whisk up your eggs, milk, salt, pepper, garlic, and heavy cream, Then stir in your mix-ins! Pop the egg mixture into the refrigerator to chill while you roll out your puff pastry.

Step 2: Roll & Cut Puff Pastry. I like to roll it a bit just to stretch how much you can get out of each sheet. Cut each sheet into 12 squares, and place them into a muffin tin prepared with non-stick spray. 

Step 3: Fill and Bake. Add a few spoonfuls of the quiche filling to each cup, brush with a little egg wash (or just dip your pastry brush into the egg filling in the cup to save an egg, hah!). Bake as directed below, and enjoy immediately! 

I like to sprinkle these portable bites with a little extra pepper before serving. You can slice some green onions to garnish them, too, but don’t worry about running out to get green onions if you don’t already have some in your fridge or garden. 

Serving + Storing this Recipe:

Enjoy these little quiches hot from the oven! These are best on the first day, as the puff pastry will lose some of it’s crisp texture, but leftovers can be stored in an airtight container in the fridge for 2-4 more days. Reheat on a sheet pan in the oven to try and retain some of the crisp texture. Serve these up at baby showers, potlucks, for Easter brunch, or any time you want to serve a fun brunch at home!

Expert Success Tips:

• Bake Right Away – Don’t let the pan sit around once you’ve filled the puff pastry – bake it right away.
• Enjoy warm – Enjoy these warm from the oven! They’re best fresh.
• Oven Thermometer – An oven thermometer will tell you if your oven is actually running at the temperature you set it to. Your oven may not be accurate. Accurate oven temperature is crucial for most bakes, so I leave an oven thermometer in at all times to keep an eye on my oven’s calibration.

Recipe Variations:

• Customizable Mix-Ins – Customize these mini quiches with ingredients on hand! I love a mix of gruyere and cheddar cheese, but any type of cheese will work – swiss would be delicious with the cheddar! Don’t have any spinach? That’s fine, it can be omitted! You can leave out the meat entirely, or use ham or breakfast sausage instead. If you can’t find puff pastry, pie crust would work too. Mushrooms would be delicious in these – I would chop them and give them a sauté first, with a little salt and pepper!

Special Tools:

• Muffin Pan – You’ll need a standard size cupcake or muffin tin for this recipe.
