Ingredients Method

Ingredients

  

• 1 teaspoon olive oil or avocado oil
• 1/2 small yellow onion, finely diced (optional but adds flavor)
• 1 cup cremini or button mushrooms, sliced
• 2 cups fresh baby spinach, loosely packed
• 1 cup liquid egg whites (or 6 large egg whites)
• 1 small garlic clove, minced (or 1/4 teaspoon garlic powder)
• Salt and freshly ground black pepper, to taste
• Pinch of red pepper flakes (optional)
• Optional toppings: 1–2 tablespoons feta or goat cheese, chopped fresh parsley or chives, a squeeze of lemon

Method

 

1. Prep your ingredients: Slice the mushrooms, dice the onion, and mince the garlic. Rinse and pat the spinach dry.
2. Heat the pan: Set a nonstick skillet over medium heat. Add the oil and let it warm until it shimmers.
3. Sauté aromatics: Add the onion with a pinch of salt. Cook 2–3 minutes, stirring, until it softens. Stir in the garlic and cook 30 seconds, just until fragrant.
4. Cook the mushrooms: Add the sliced mushrooms. Spread them out so they make contact with the pan. Cook 3–4 minutes, stirring occasionally, until they release their moisture and turn golden around the edges. Season with a little salt and pepper.
5. Wilt the spinach: Add the spinach to the pan. Toss with the mushrooms until it wilts down, about 1 minute. If using red pepper flakes, sprinkle them in now.
6. Add the egg whites: Pour in the egg whites and reduce the heat to medium-low. Let them sit for 10–15 seconds, then gently push with a spatula from the edges toward the center, creating soft curds.
7. Scramble to your preferred texture: Continue gently folding and pushing the egg whites until just set and slightly glossy. This usually takes 2–3 minutes. Avoid overcooking.
8. Finish and season: Turn off the heat. Taste and adjust salt and pepper. If using cheese or herbs, fold them in now. A small squeeze of lemon brightens the flavors.
9. Serve: Plate immediately while warm. Add extra herbs or a grind of pepper on top if you like.

Storage Instructions

• Refrigerate: Store leftovers in an airtight container for up to 2 days.

  The eggs will firm up slightly but still taste great.

• Reheat gently: Warm in a nonstick skillet over low heat with a splash of water to loosen, or microwave in short 20–30 second bursts to avoid rubbery texture.
• Avoid freezing: Egg whites change texture when frozen and thawed, so freezing isn’t recommended.

Health Benefits

• Lean protein: Egg whites provide high-quality protein to support muscle repair and satiety without extra fat or cholesterol.
• Fiber and micronutrients: Spinach brings iron, folate, vitamin K, and vitamin C, while mushrooms add B vitamins, selenium, and antioxidants.
• Low-calorie, nutrient-dense: You get a lot of nutrition for relatively few calories, making it great for weight management and balanced eating.
• Supports energy: The combination of protein and micronutrients helps keep energy levels steady through the morning.

What Not to Do

• Don’t overcook the egg whites: They go from tender to rubbery quickly. Pull them off the heat while slightly glossy.
• Don’t crowd the mushrooms: If the pan is packed, they steam instead of brown. Cook in two batches if needed.
• Don’t skip seasoning: A pinch of salt at each step builds flavor.

  Add pepper and a fresh element (lemon or herbs) at the end.

• Don’t use high heat for the eggs: Medium-low is best for soft, fluffy curds.

Alternatives

• Add whole eggs: Swap half the egg whites for 1–2 whole eggs for a richer flavor and creamier texture.
• Dairy-free creaminess: Stir in a spoonful of unsweetened almond milk or cashew cream near the end.
• Cheese options: Try feta, goat cheese, shredded cheddar, or Parmesan. Add at the end so it melts gently.
• Veggie swaps: Replace spinach with kale, arugula, or Swiss chard. Use bell peppers, cherry tomatoes, or zucchini instead of mushrooms.
• Herb and spice twists: Add smoked paprika, Italian seasoning, or cumin.

  Fresh dill, basil, or chives brighten the dish.

• Protein boost: Toss in diced turkey, smoked salmon, or leftover roasted chicken for extra protein.
• Make it a wrap: Spoon the scramble into a whole-grain tortilla with avocado and salsa for a quick breakfast wrap.

FAQ

Can I use frozen spinach?

Yes. Thaw it first and squeeze out as much water as possible. Add it to the pan after the mushrooms are cooked, and warm it through before adding the egg whites.

How do I keep egg whites from sticking?

Use a good nonstick skillet, preheat the pan, and add a small amount of oil.

Keep heat at medium-low once the egg whites go in, and use a silicone or rubber spatula to gently move them around.

Are carton egg whites the same as fresh?

Carton egg whites are pasteurized and convenient. Freshly separated egg whites work just as well. The texture and taste are very similar; use whichever you prefer.

How can I make this more filling?

Serve the scramble with whole-grain toast, avocado slices, or roasted sweet potatoes.

You can also add a handful of black beans or quinoa for extra fiber and staying power.

What’s the best cheese for this scramble?

Feta and goat cheese add tang and creaminess without needing much. If you prefer something melty, try shredded cheddar or mozzarella, added right at the end.

Can I prep this ahead?

You can chop the vegetables the night before and store them in the fridge. Cook fresh in the morning for the best texture, which still only takes a few minutes.

Is it okay to add the garlic earlier?

Garlic burns easily, so it’s best added after the onion softens or just before the mushrooms finish cooking.

Burnt garlic tastes bitter.
