Baked Egg White & Spinach Muffins
Ingredients
- 2 cups liquid egg whites or 12 egg whites, separated
- 1 cup fresh spinach chopped (or use thawed frozen spinach, squeezed dry)
- ½ cup bell pepper diced (any color)
- ¼ cup red onion finely chopped
- ¼ cup low-fat shredded cheese optional, adds flavor & creaminess
- 2 tbsp milk dairy or non-dairy, helps with fluffiness
- ½ tsp garlic powder
- ½ tsp salt adjust to taste
- ¼ tsp black pepper
- Optional Add-Ins:
- Mushrooms zucchini, or broccoli (chopped small)
- Feta cheese mozzarella, or goat cheese
- Fresh herbs like parsley basil, or chives
- A pinch of red pepper flakes for heat
Instructions
- Preheat the Oven:
- Heat oven to 350°F (175°C). Lightly grease a 12-cup muffin tin with cooking spray or line with silicone baking cups.
- Prep the Vegetables:
- Chop spinach, peppers, and onions into small pieces. (Tip: squeeze out excess moisture from spinach to prevent soggy muffins.)
- Mix the Base:
- In a large bowl, whisk together egg whites, milk, garlic powder, salt, and black pepper until frothy. This adds air for fluffier muffins.
- Assemble the Muffins:
- Divide spinach, peppers, onions, and cheese (if using) evenly among the muffin cups. Pour the egg white mixture over the top, filling each cup about ¾ full.
- Bake Until Set:
- Place the muffin tin in the oven and bake for 20–25 minutes, or until the muffins are puffed, set in the center, and lightly golden around the edges.
- Cool & Release:
- Allow muffins to cool for 5 minutes before gently loosening with a knife or spatula. They will deflate slightly as they cool — this is normal.
- Serve & Enjoy:
- Enjoy warm, or let them cool completely before storing for meal prep.
Pro Tips & Variations
- Make Them Cheesy – Mix in shredded cheddar, feta, or mozzarella for added flavor and creaminess.
- Veggie-Packed – Add mushrooms, zucchini, or broccoli for extra nutrients. Just make sure to sauté or squeeze out moisture first to avoid sogginess.
- Spice It Up – Add jalapeños, red pepper flakes, or a splash of hot sauce to the egg mixture for a kick.
- Protein Boost – Stir in diced turkey bacon, chicken sausage, or smoked salmon if you’re not keeping them vegetarian.
- Dairy-Free Option – Skip the cheese and use non-dairy milk.
- Storage & Reheating –
- Store cooled muffins in an airtight container in the fridge for up to 4 days.
- Freeze individually on a baking sheet, then store in a freezer bag for up to 2 months.
- Reheat in the microwave (30–45 seconds) or in the oven at 325°F (160°C) until warmed through.
