Low Sodium Egg White and Spinach Frittata
A gentle small-batch breakfast made in one ovenproof skillet with simple ingredients and mild seasonings for a soft, easy-to-chew texture.

Ingredients You’ll Need

- 4 large egg whites (about 4 eggs) or 3/4 cup liquid egg whites, plus 1 tablespoon plain low-fat yogurt
- 1 cup fresh spinach chopped, 1 small shallot or 2 green onion tops sliced, 1 small garlic clove minced optional
- 1 teaspoon olive oil, 1/8 teaspoon black pepper, 1/4 teaspoon dried oregano, optional 1 tablespoon shredded part-skim mozzarella
Serves 1 to 2. Serve with steamed soft vegetables, mashed potatoes, or a slice of soft bread for a gentle meal.
Step-by-Step Recipe

- Preheat the oven to 350 F and lightly oil a 6 to 8-inch ovenproof skillet. Heat skillet over medium-low and add oil, then cook the sliced shallot or green onion 2 minutes until softened; add garlic and chopped spinach and cook 1 to 2 minutes until wilted, then spread vegetables evenly in the pan.
- Whisk the egg whites with the yogurt, black pepper, and dried oregano until smooth. Pour the mixture over the vegetables, let sit 30 seconds to begin setting, then transfer the skillet to the oven.
- Bake 12 to 15 minutes until the center is set and the top is slightly puffed. For an extra-soft texture bake toward the shorter time and let rest covered 2 minutes. Top with optional low-sodium cheese or extra herbs, slice into two pieces and serve warm.
Tips and Easy Variations
Texture tips
- Bake slightly longer at lower heat and let rest covered to relax the texture for easier chewing
- Cut into small pieces and serve with a creamy side like mashed sweet potato or yogurt for softer bites
- Use yogurt in the eggs to keep the frittata tender and creamy
Gentle digestion choices
- Choose plain or lactose-free yogurt and avoid raw crunchy add-ins
- Use steamed spinach and cooked shallot rather than raw vegetables
- If needed pick a dairy-free yogurt for sensitivity to dairy
Flavor swaps
- Replace salt with lemon zest, fresh parsley, or a pinch of smoked paprika for brightness without sodium
- Swap spinach for finely chopped kale or Swiss chard that has been cooked first
- Add a tablespoon of ricotta or a small diced cooked sweet potato for extra creaminess and softness
Quick low-sodium ideas
- Use herbs and citrus zest instead of salt for bright flavor
- Top with no-salt seasoning or a small sprinkle of low-sodium cheese if desired
- Test texture by baking slightly less and letting it rest to finish setting

FAQ
Can I use frozen spinach?▶
Yes. Thaw frozen spinach and squeeze out excess water before adding to the pan so the frittata does not become watery.
Can I add a whole egg for richness?▶
You can add one whole egg if you prefer a richer texture. That will increase cholesterol slightly so follow any guidance your doctor gave you.
