How to Make High-Protein Egg Muffins
1. Prep the pan
Grease a 12-count muffin tin or silicone mold well.
Tip: Silicone molds take longer to bake — details below.
2. Whisk the eggs
In a medium bowl, whisk the eggs until smooth and combined.
3. Add veggies & mix-ins
Stir in your chopped veggies, cheese, and seasonings.
4. Fill the muffin cups
Pour the mixture evenly, filling each cup about ¾ full to avoid overflow.
5. Bake
Metal muffin tin: 350°F for 15–18 minutes
Silicone mold: 350°F for 18–22 minutes
The centers should be set, not jiggly.
6. Cool & serve
Let them rest for 3–5 minutes before removing — they firm up as they cool.
Expert Tips for Perfect Egg Muffins (No Wobbly Centers!)
1. Silicone molds bake slower
Silicone does not conduct heat like metal.
→ Increase bake time to 18–22 minutes.
2. Avoid watery veggies
Tomatoes, spinach, zucchini, and mushrooms release water.
→ Pat dry, sauté lightly, or use less of them.
3. Place silicone molds on a metal sheet
This helps the heat distribute evenly and prevents undercooked centers.
4. Don’t overfill
¾ full is ideal — too much liquid makes them collapse.
5. Let them cool before removing
This helps the structure set and prevents tearing.
Troubleshooting: Why Are My Egg Muffins Wobbly or Wet?
If the center is still jiggly, here’s why:
Underbaked — simply pop back in for 5–8 more minutes.
Silicone pan — needs a longer bake.
Too many watery veggies — adds moisture.
Cold eggs or ingredients — slows baking time.
To fix:
Bake an extra 5–10 minutes, checking with a toothpick. It should come out mostly dry.
How to Store & Meal Prep Egg Muffins
Refrigerate: Store in an airtight container up to 4 days.
Freeze: Let cool completely. Freeze in a freezer-safe bag or container for up to 2 months.
Reheat:
Microwave: 20–30 seconds
Air fryer: 2–3 minutes at 350°F
Oven: 5 minutes at 300°F

FAQ — High-Protein Egg Muffins
Can I add milk or cream?
Yes, but only 1–2 tablespoons. Too much liquid makes them soft and watery.
Can I use egg whites only?
Yes — use 1 cup egg whites. They’ll bake slightly faster.
How do I keep them fluffy?
Whisk well, don’t pack in too many mix-ins, and bake until just set.
Do they collapse after baking?
Only if they’re undercooked or overloaded with veggies. Let them cool to set.
