1. Crank your oven to 350°F (180°C) and generously grease a standard 12-cup muffin tin with non-stick cooking spray. Get the sides and bottom of each cup really well or you’ll regret it later.
2. Crack the eggs into a mixing bowl, add the milk, salt, and pepper, then whisk everything together until well combined and slightly frothy. Whisk longer than you think you need to—this adds air for fluffier muffins.
3. Stir in the diced bell peppers, diced zucchini, diced onions, chopped spinach, and shredded cheddar cheese. Make sure everything’s chopped small and uniform so it distributes evenly.
4. Pour the egg and vegetable mixture into your prepared muffin tin, filling each cup about 3/4 full. Use a 1/4 cup measuring cup to portion them out evenly—they’ll all cook at the same rate this way.
5. Bake for 20-25 minutes until the muffins are set and slightly golden on top. They should puff up beautifully and the centers should be firm when you gently press them.
6. Let them cool in the pan for about 5 minutes—this is crucial for easy removal. Run a butter knife around the edges to loosen them, then pop them out carefully.
7. Serve warm or let cool completely before storing in an airtight container in the fridge for up to 5 days. Reheat for 30 seconds in the microwave when you’re ready to eat.

Notes:

• Seriously, grease that pan generously or you’ll be scraping stuck egg for twenty minutes
• Whisk the eggs until frothy for maximum puff—streaky eggs make dense muffins
• Dice vegetables small and uniform so they distribute evenly
• Don’t overfill the cups or they’ll spill over and create a mess
• They continue cooking from residual heat, so don’t overbake
• Let them cool for 5 minutes before removing or they’ll fall apart

Storage Tips:

• Keep in an airtight container in the fridge for up to 5 days
• Freeze individually wrapped in plastic wrap for up to 3 months
• Reheat refrigerated muffins in the microwave for 30-45 seconds
• Reheat frozen muffins for 60-90 seconds, or thaw overnight first
• They’re actually pretty good cold straight from the fridge if you’re really rushed
• Don’t stack them while still warm or the condensation makes them soggy

• With toast: Serve alongside whole grain toast with avocado for a complete breakfast
• Breakfast sandwich: Split a muffin and stuff it in an English muffin for portable breakfast
