Instructions

1. Prepare the Oven

• Preheat the oven to 375°F (190°C).

2. Add the garlic powder, onion powder, smoked paprika, salt, and pepper.
3. Stir in the cheddar cheese, mozzarella, green onions, bell pepper, spinach, and mushrooms.

3. Fill the Muffin Cups

1. Divide the mixture evenly among the muffin cups, filling each about ¾ full.

4. Bake

• Bake for 18–22 minutes, or until the egg muffins are puffed, lightly golden, and set in the center.

Tips for the Best Egg Muffins

• Finely chop the vegetables so they cook evenly.
• Sauté mushrooms first to remove excess moisture.
• Avoid overfilling the muffin cups, as the eggs will puff during baking.
• Let the muffins cool slightly before removing them from the pan.
• Silicone muffin liners make removal especially easy.

Frequently Asked Questions

Can I make these ahead of time?

Yes! They’re ideal for meal prep and can be refrigerated or frozen for quick breakfasts.

Why did my egg muffins deflate?

Egg muffins naturally puff up in the oven and settle slightly as they cool. This is completely normal.

How do I keep them from sticking?

Grease the muffin tin well or use silicone muffin liners for easy removal.

Can I add different vegetables?

Absolutely. Broccoli, zucchini, asparagus, kale, tomatoes, and mushrooms all work well. Be sure to cook vegetables with high water content first.

Are these low-carb?

Yes. Each muffin contains approximately 1.5g net carbs, making them an excellent low-carb and keto-friendly breakfast.

What can I serve with egg muffins?

They pair well with avocado, fresh fruit, Greek yogurt, cottage cheese, turkey bacon, breakfast sausage, or a simple green salad.
