These Spinach and Feta Muffin Pan Frittatas are one of my favorite ways to make eggs. When I worked at the bakery I made at least two whole frittatas a day and double that on weekends. I loved how I could change up the flavors with different vegetables, cheeses, herbs, and proteins.

Once you have a good base recipe for a frittata, you can add any mix-ins you have around the kitchen (hello leftovers) and always make something new and delicious! Pouring your frittata into a muffin pan takes it to the next level, allowing you to make a dozen individual frittatas that are perfect for breakfast, lunch, or a snack. Baked in a mini muffin pan, you have an irresistible hors d'oeuvre!

Substitutions

My goal is always to make it easy for you to make my recipes. Here are a few substitutions you can make if you need:

• Cheese -Change up the cheese with whatever you have on hand or prefer. I find 3 to 4 ounces of cheese is the perfect amount.
• Milk - You can easily replace the heavy cream with regular milk, half and half, or your favorite non-dairy milk.
• Spinach - If you don't have spinach you can replace it with an equal amount of chopped kale, chard, or other leafy green.
• Mini sweet peppers - If you don't have/can't find mini sweet peppers, feel free to use regular peppers. Because they are responsible for so much of the flavor, I would recommend only red or orange peppers as the green and yellow ones may be too bitter.

Variations

My favorite thing about these Mini Frittatas is that there are an infinite number of ways you can make them your own. Here are a few of my favorites that I used to make in the bakery back in the day:

• Bonjour - Add caramelized onion and Swiss cheese to give them a French Onion flavor.
• Fancy that - Add a pastry crust, bacon and cheese and make Mini Quiche Lorraine.
• Comfort - Bacon, potato, and cheddar will bring in a loaded potato vibe.
• Soup's on - Broccoli and cheddar are a forever classic combo.
• Mix & Match - You have a dozen ways to make these unique! Add the fillings everyone wants, fill up with eggs, and bake!

Equipment

I'm pretty sure everyone has a muffin pan at their disposal, but do you have the best one for these Muffin Pan Frittatas? Having owned quite a few crummy pans in my life, I have no problem paying a bit extra for a high quality nonstick muffin pan. Mine has more than paid itself in muffins that come right out of the pan without a paper liner.

If you don't have a nonstick muffin pan, I would not recommend using muffin liners as the eggs will definitely stick to the paper. Instead, spray each well generously with nonstick spray,or grease well with a neutral oil. Then run a paring knife around the mini frittatas when they first come out of the oven to encourage them to unstick.

Instructions

These Muffin Pan Frittatas are so easy to make, you'll be playing with the recipe in no time! Start by preheating your oven to 375°F and spraying all of the wells of your muffin pan with nonstick spray.

Step 1: Cut your onion and your sweet peppers in a small dice (no one wants a huge hunk of onion).

Step 2: Chop your spinach into bite sized pieces, but not too small, as it will wilt a lot.

Step 3: Sauté your onions and peppers until soft. Add the spinach.

Step 4: Continue to sauté everything until the spinach is wilted. Remove from the pan and place on a paper towel lined plate to absorb excess water (no soggy frittatas).

Step 5: While the vegetables cool, crack your eggs and add your heavy cream to a large bowl.

Step 6: Add salt and pepper and whisk until the whites and yolks are uniformly mixed.

Step 7: Divide the vegetables evenly among each of the wells.

Step 8: Crumble about a tablespoon of feta into each cup and then pour ¼ cup of egg mixture on top of each. Mix lightly to ensure the vegetables and cheese are dispersed in the egg.

Step 9: Crumble more feta on top.

Step 10: Sprinkle with chopped chives, if desired.

Step 11: Bake at 375°F for 20 to 25 minutes or until muffin pan frittatas are puffy and set. If you are unsure if your mini frittatas are done, insert a paring knife or skewer into the center of one. If it comes out clean, breakfast is ready!

Garnish with more chives and serve!

Hint: If you want puffier spinach and feta muffin pan frittatas, try mixing your eggs and cream with an immersion blender to introduce more air into them. Even without that step, some of the mini frittatas will puff up more than others, but they will all deflate as they cool. That is normal.
