Ingredients You’ll Need

- 1 teaspoon olive oil
- 1 small shallot or 1/4 small yellow onion, finely chopped
- 3/4 cup sliced mushrooms, about 3 to 4 ounces
- 1 cup fresh spinach, packed
- 3 large eggs
- 2 tablespoons low-fat milk or plain yogurt
- 1/8 teaspoon black pepper, or to taste
- 1/4 teaspoon garlic powder
- 1 tablespoon chopped fresh parsley or 1 teaspoon dried
- Juice of 1/4 lemon or a few drops to brighten flavors
- Optional: 1 ounce low-sodium feta or a sprinkle of low-sodium cheese
You can serve this frittata with a slice of soft toast or a piece of soft low-sodium bread if you like.
Step-by-Step Recipe

- Preheat oven to 375 F (190 C). Have an ovenproof 8-inch skillet ready.
- In the skillet, warm the olive oil over medium heat. Add the chopped shallot and cook 1 to 2 minutes until fragrant and soft.
- Add the sliced mushrooms and cook, stirring occasionally, until they release their moisture and become very tender, about 4 to 6 minutes. Break them into small pieces for an easier chew.
- Add the spinach and cook just until wilted, about 30 to 60 seconds. Remove the pan from heat and let cool a moment.
- In a bowl, whisk the eggs with milk or yogurt, black pepper, garlic powder, parsley, and lemon juice. If reducing dairy for digestion, use water or extra milk instead of yogurt.
- Pour the egg mixture over the vegetables in the skillet and give the pan a gentle shake so eggs settle evenly. If using low-sodium cheese, sprinkle it on top now.
- Cook on the stovetop over low heat for 1 minute to set the edges, then transfer the skillet to the oven. Bake 10 to 12 minutes until the center is set but still slightly soft. Avoid overbaking to keep a tender texture.
- Let the frittata rest 3 to 5 minutes before slicing. Serve warm.
Tips and Easy Variations
Texture and digestion
- Add 1 tablespoon ricotta or plain yogurt to the egg mix for a creamier, gentler bite.
- Chop mushrooms very small and cook longer until they are very soft to make chewing easier.
- Use two egg whites plus one whole egg or substitute half the milk with water for a lighter dish.
Lower sodium and swaps
- Skip added salt and use lemon and herbs for bright flavor.
- Choose low-sodium feta or omit cheese entirely if advised to limit sodium.
- For dairy free, use unsweetened plant milk and skip the cheese or add mashed tofu for creaminess.
Vegetable variations
- Try mild greens such as baby kale or chard but cook them a bit longer so they soften.
- Soft-cooked bell peppers, zucchini, or thinly sliced leeks can be added if cooked until tender.
- Pulse cooked veggies briefly in a food chopper for a finer texture before adding eggs.
Quick gentle eating tips
- Chop vegetables small and cook until very soft for an easier bite.
