Ingredients for Egg White Spinach Breakfast Bake (Low Carb)

Here’s everything you’ll need to make this simple yet flavorful breakfast bake. I’ve learned through trial and error that precise measurements matter here – especially with the egg whites!

• 6 large egg whites (about 3/4 cup liquid egg whites if you’re using carton)
• 1 cup fresh spinach, chopped (pack it lightly when measuring)
• 1/4 cup diced onions (I prefer sweet yellow onions for this)
• 1/4 cup diced bell peppers (any color works, but red adds nice sweetness)
• 1/4 cup shredded low-fat cheese (I use cheddar, but see substitutions below)
• 1/2 tsp salt (I use fine sea salt for even distribution)
• 1/4 tsp black pepper (freshly ground if you have it)
• 1/2 tsp garlic powder (not garlic salt – that would make it too salty)
• 1 tbsp olive oil (for sautéing the veggies)

Ingredient Notes & Substitutions

Don’t stress if you’re missing something – this recipe is super flexible! Here are my favorite swaps:

• Swap spinach for kale (just massage it first to soften) or Swiss chard
• Add turkey bacon or diced ham for extra protein (about 1/4 cup)
• Any shredded cheese works – try mozzarella for stretchiness or feta for tang
• Make it dairy-free by skipping cheese or using nutritional yeast
• For extra kick, add diced jalapeños or red pepper flakes

See? Plenty of ways to make this your own while keeping it low-carb and delicious!

How to Make Egg White Spinach Breakfast Bake (Low Carb)

This recipe couldn’t be simpler – I’ve perfected the method after making it practically every Sunday for the past year! The secret is in the order: sauté the veggies first to develop flavor, then gently fold them into the whipped egg whites. You’ll be amazed how something so easy turns out looking (and tasting) so fancy!

Step-by-Step Instructions

1. Preheat your oven to 350°F (175°C) – this gives it time to reach the perfect temperature while you prep.
2. Sauté the veggies: Heat olive oil in a skillet over medium. Cook onions and bell peppers for 2-3 minutes until they start to soften. Add spinach and cook just until wilted (about 1 minute – don’t overcook!).
3. Whisk the egg whites vigorously with salt, pepper, and garlic powder until slightly frothy – this helps them puff up beautifully in the oven.
4. Combine everything by folding the sautéed veggies into the egg whites – gentle folding keeps the mixture light.
5. Pour into a greased 8×8 baking dish (I use avocado oil spray for easy release) and sprinkle cheese evenly on top.
6. Bake 20-25 minutes until the center is set and the edges turn golden. Let it cool for 5 minutes before slicing – trust me, this prevents crumbling!

Tips for Perfect Egg White Spinach Breakfast Bake (Low Carb)

• Grease well: Egg whites stick like crazy – I rub butter in every crevice of my baking dish.
• Undercook veggies slightly: They’ll continue cooking in the oven, so stop when spinach is just wilted.
• Taste your mix: Before baking, dip a spoon in to check seasoning – egg whites need more salt than you’d think!
• Use room temp eggs: They whip up fluffier than cold ones straight from the fridge.

Serving & Storing Egg White Spinach Breakfast Bake (Low Carb)

Okay, here’s how I love to serve this beauty – fresh from the oven with avocado slices on the side for creamy richness, or a dollop of salsa if I’m craving something zesty. Sometimes I’ll pair it with whole-grain toast when I’m feeling fancy, but honestly, it’s perfect all on its own!

For storage (because let’s be real, I always make extra), pop leftovers in an airtight container in the fridge for up to 3 days. To reheat, I just microwave single portions for 45 seconds – or for that fresh-baked feel, warm slices in a 300°F oven for about 10 minutes. The cheese gets all melty again, and it’s like morning magic all over!

Nutritional Information for Egg White Spinach Breakfast Bake (Low Carb)

Now let’s talk numbers – because I know you’re curious about what’s fueling your morning! Based on my exact ingredients (using cheddar cheese and no extra add-ins), here’s the breakdown per serving:

• 150 calories – light but satisfying
• 15g protein – hello, muscle fuel!
• 5g carbs (4g net carbs)
• 7g fat (mostly from the olive oil and cheese)

Remember – these numbers will shift if you swap ingredients (like using full-fat cheese or adding turkey bacon). But no matter how you tweak it, this bake stays firmly in the low-carb, high-protein breakfast club!

FAQ About Egg White Spinach Breakfast Bake (Low Carb)

I get so many questions about this recipe – here are the ones that pop up most often:

Can I use whole eggs instead of just egg whites? Absolutely! Swap in 3 whole eggs for the 6 whites if you prefer. The texture will be slightly denser but just as delicious. You’ll get about 190 calories per serving this way.

Is this breakfast bake freezer-friendly? You bet! I freeze individual portions all the time. Just wrap slices tightly and freeze for up to 2 months. Thaw overnight in the fridge, then reheat in the oven at 300°F for best results.

How can I spice it up? My favorite ways are adding a pinch of cayenne to the egg mixture or topping with hot sauce after baking. Diced jalapeños work great too – toss them in with the bell peppers when sautéing.

Can I make it ahead? Oh honey, that’s half the beauty! Prep everything the night before – just combine the cooked veggies and egg whites in your baking dish, cover, and refrigerate. In the morning, sprinkle cheese and pop it straight into a preheated oven.
