What Are Egg Muffins?
Egg muffins are essentially mini frittatas that are made by mixing together scrambled eggs with savoury fillings such as veggies, meats, and cheese. When baked, they produce a soft and fluffy texture that's bursting with delicious goodness. I especially love how easy they are to meal prep and just grab-and-go during those busy mornings - it makes my mornings so much easier knowing I've got a healthy and hearty breakfast waiting for me, without the hassle of whipping up a fresh omelette from scratch each morning.

Ingredients
Please see recipe card below for exact quantities.
- Egg base: eggs, egg whites, taco seasoning
- Fillings: ground pork sausage, red and green peppers, onions, corn, taco seasoning
- Toppings: shredded Tex Mex cheese, red chili flakes
Substitutions
There are so many ingredients you can use as substitutions.
- Eggs - instead of using whole eggs, you can substitute ¼ cup (60 ml) of liquid egg whites for every 1 large egg you want to replace.
- Meats - instead of ground pork sausage, you can use chorizo, ground beef, or ground turkey for a leaner option.
- Veggies - while red and green peppers, onions, and corn are typically common in Tex Mex taco dishes, you can also add black beans, chiles or jalapeños for a kick.
- Tex Mex cheese - instead of a Tex Mex blend, you can use cheddar or Monterey Jack.
- Taco seasoning - if you don't have taco seasoning at home, you can use a more simplified combination of chili powder, paprika, garlic powder, onion powder, and cumin.
Instructions

STEP 1: Prep ingredients by finely chopping vegetables and grating any cheeses if necessary. Make sure to cut everything into small pieces to ensure even distribution throughout the egg muffins.

STEP 2: In a skillet over medium-high heat, sauté the ground pork sausage for a few minutes until browned and in tiny pieces.

STEP 3: Add in chopped vegetables and sauté for a few minutes. Mix in taco seasoning until well combined, and then remove from heat to set aside.

STEP 4: In a large measuring cup or mixing bowl, mix the egg base ingredients with a whisk.

STEP 5: Grease a 6-cup muffin tin with cooking spray (or double the ingredients if using a 12-cup muffin tin). Then add in the sautéed ingredients, distributing them evenly in each cup.

STEP 6: Pour the egg mixture into each cup in equal portions. Sprinkle the cheese and chili flakes on top.

STEP 7: Bake it in the oven for 20 minutes at 350°F/177°C, or in the air fryer for 12-15 minutes at 300°F/149°C.

STEP 8: When done, take it out and let it cool down for a few minutes. The egg muffins should slide right out with a butter knife. Enjoy!
Equipment
When it comes to baking, I love using my compact mini oven from Breville. It not only spares me the hassle of firing up my main oven (and heating up the whole kitchen), but it also pre-heats much faster, while delivering perfectly cooked results every single time. As for air frying, my go-to is this dedicated air fryer from Cosori. It cooks very quickly with perfect results every time, and the basket is a breeze to clean.

Storage
These egg muffins are meal prep champions thanks to their excellent storage capabilities. Pop them in the fridge, and they'll stay fresh for up to 4 days. If you need them to last longer, just stick them in the freezer where they'll stay fresh for 2 to 3 months. Just remember to store them in an airtight container with a secure lid to keep them fresh and prevent freezer burn.
Toasty's Tips
- Whisk your egg mixture in a large measuring cup instead of a mixing bowl. It's much easier to pour when you're portioning out the mixture into the muffin tin cups.
- Feeling adventurous? Add some chopped chiles or jalapeños for an extra spicy kick!
- Got leftovers in the fridge? Perfect! Use up those veggies and meats by whipping up a batch of egg muffins whenever you have ingredients to spare.
- When chopping up ingredients, dice them into tiny pieces for even distribution throughout the batter, ensuring every bite is packed with flavor.

FAQ
Can I make this in the microwave?
While I suggest baking in an oven or air fryer for optimal results, you can also cook your egg mixture in the microwave. Just pour and mix the ingredients into a microwave-safe container, like a greased ramekin or coffee mug. Heat it on high for roughly 60 seconds (microwave cooking times vary). Check for doneness, and if necessary, continue reheating in short increments (about 10 seconds at a time) until fully cooked.
Can I use fewer eggs?
For sure! To reduce the number of eggs in your recipe, you can easily substitute 1 large egg with ¼ cup (60 ml) of liquid egg whites. For instance, if your recipe calls for 6 eggs, you could use 4 eggs plus ½ cup (125 ml) of egg whites, or 2 eggs plus 1 cup (250 ml) of egg whites. However, I suggest keeping at least some whole eggs in the mix to maintain that spongy and fluffy texture when baked.
Why are my egg muffins sticking to the muffin tin after baking?
Be sure to grease the insides of your muffin tray cups with cooking oil or spray before pouring in your egg batter. After pouring, refrain from stirring the egg mixture. If needed, gently run a butter knife along the edges of the egg muffin before baking. For easier removal, consider using silicone muffin cups that fit snugly into the tray and can be effortlessly popped out after baking.
