Instructions

1

Rinse the barley and cook it in plenty of lightly salted water for about 25–30 minutes until tender, then drain well.

2

Preheat the oven to 190°C (375°F).

3

Heat the olive oil in an oven-safe skillet over medium heat. Add the sliced mushrooms and cook for 5–6 minutes until golden and their moisture has evaporated.

Add the minced garlic and cook for 1 more minute, then stir in the cooked barley and season with half the salt and pepper.

5

In a bowl, whisk the eggs with the grated parmesan, chopped parsley, and the remaining salt and pepper.

6

Pour the egg mixture evenly over the barley and mushrooms in the skillet, shaking gently to distribute.

7

Cook on the stovetop over low heat for 3–4 minutes until the edges begin to set.

8

Transfer the skillet to the oven and bake for 12–15 minutes until the frittata is fully set and lightly golden on top.

9

Let the frittata rest for 5 minutes, slice, and serve warm.

FAQ

Can I use pre-cooked barley for this frittata?
Yes. Use about 2 cups of cooked barley and skip the boiling step. Pat it dry if it is very moist.
Is this frittata gluten-free?
No. Barley contains gluten. For a gluten-free version, use cooked quinoa or another certified gluten-free grain.
What type of skillet should I use?
Use a well-seasoned cast-iron or other oven-safe skillet. Make sure it can safely withstand 190°C (375°F).
How can I tell when the frittata is done?
The center should be set with no liquid egg visible, and the top should be lightly golden. Avoid overbaking so it stays tender.
Can I make this frittata without dairy?
Yes. Omit the Parmesan or replace it with a dairy-free alternative. You may want to adjust the salt to taste.
Can I prepare the barley or vegetables in advance?
Yes. Cook the barley and mushrooms up to one day ahead, refrigerate them promptly, and assemble the frittata when ready.
How should I store leftovers?
Cool leftovers promptly, cover them, and refrigerate for up to 2 days. Reheat thoroughly before serving.
Can I use different mushrooms or herbs?
Yes. Button, cremini, or mixed mushrooms work well. Chives or basil can replace the parsley.
How many servings does this recipe make?
It makes 2 servings. Serve it with a salad or other colorful vegetables for a more complete meal.
