Mix and match up to 1½ cups total:

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.
