High-Protein Veggie Egg Muffins (The Best Diet Breakfast Food You'll Actually Eat)

Ingredients

• 8 large eggs
• 1/4 cup unsweetened almond milk (or regular milk)
• 1/2 cup baby spinach, roughly chopped
• 1/3 cup red bell pepper, finely diced
• 1/4 cup red onion, finely diced
• 1/3 cup cherry tomatoes, halved
• 1/3 cup crumbled feta cheese
• 1/4 tsp garlic powder
• 1/4 tsp black pepper
• 1/2 tsp sea salt
• 1 tsp olive oil (for greasing the tin)
• Optional: pinch of chili flakes if you like a little heat

Instructions

1. 1

   Heat your oven and prep the tin

   Preheat your oven to 375°F (190°C). Lightly grease a 12-cup muffin tin with olive oil or use silicone muffin cups—trust me, the silicone ones make cleanup so much easier. Set aside while you prep everything else.

2. 2

   Whisk the egg base

   Crack all 8 eggs into a large mixing bowl and add the almond milk, garlic powder, salt, and black pepper. Whisk until fully combined and slightly frothy. This is your base—it'll distribute evenly across all 12 cups, so don't skip the whisking.

3. 3

   Distribute your vegetables

   Divide the spinach, bell pepper, red onion, and cherry tomatoes evenly across all 12 muffin cups. Don't pack them too tight—you want about 2/3 of each cup filled with veggies so there's room for the egg mixture. Sprinkle the feta on top of the vegetables in each cup.

4. 4

   Pour in the egg mixture

   Carefully pour the egg mixture over the vegetables in each cup, filling them to about 3/4 full. They will puff up in the oven, so give them a little room. A small ladle or a measuring cup with a spout makes this way less messy.

   

5. 5

   Bake until just set

   Bake for 20-22 minutes, until the egg muffins are puffed up, set in the center, and lightly golden on top. A toothpick inserted in the center should come out clean. Let them cool in the tin for 5 minutes before removing—they'll deflate a little, which is totally normal.

6. 6

   Cool and store (or eat immediately)

   Eat 2-3 warm right now, or let them cool completely before transferring to an airtight container for the week ahead. These are genuinely one of those diet breakfast foods that taste just as good reheated—90 seconds in the microwave and you're good to go.

Storage Tips

Once fully cooled, store the egg muffins in an airtight container in the fridge for up to 4 days. For longer storage, freeze them individually on a baking sheet first (about 1 hour), then transfer to a zip-lock freezer bag—they'll keep for up to 2 months. Reheat from frozen in the microwave for about 90 seconds to 2 minutes, or pop them in a 350°F oven for 10 minutes if you want them less rubbery. Don't store them warm or stacked—they'll get soggy, and nobody wants that on a Tuesday morning.
