I’ve been growing Swiss chard in a container on my porch, and now that fall has arrived, it’s time for a big harvest! Chard is packed with vitamins and nutrients, and I love how productive it can be even in a small space. - This frittata is easy to make on a Saturday morning, packs nutrients - mainly protein and fat - and can be saved in the fridge or frozen in batches for the rest of the week.
A hearty, rustic frittata that makes the most of fresh garden chard, potatoes, savory sausage, and pockets of melty mozzarella. It has a little Hungarian-inspired character thanks to the sausage—chorizo works beautifully when Hungarian sausage isn't available—and it's one of those wonderfully forgiving meals that is just as good the next day.
It's also perfect for batch cooking: make one big pan, enjoy a slice while it's warm, and save the rest for easy breakfasts and lunches throughout the week.
Heat a little ghee in a large oven-safe skillet or Dutch oven over medium heat.
Add the chopped onions and sauté until softened and lightly golden.

Separate the chard stems from the leaves. Chop the stems and add them to the onions. Cook for a few minutes until they begin to soften.

Add the sausage. Chorizo is a great substitute when you can't find Hungarian sausage—look for a good-quality sausage with plenty of savory paprika and garlic flavor.
Break the sausage into generous pieces rather than crumbling it too finely. Cook until browned and fragrant.
Add the cubed potatoes and gently sauté everything together.
Cook until the potatoes begin to brown and are tender enough to bite through. You want a little golden color on the potatoes without making them too soft or breaking them apart.

Roughly chop the chard leaves and add them to the pan.
Stir gently and allow the leaves to wilt into the sausage and potatoes. They will look like a lot at first, but the greens will quickly collapse as they cook.
Once the chard has wilted, reduce the heat to low.

Cut the mozzarella into small cubes and scatter them throughout the mixture.
Don't let the mozzarella melt completely into the pan. The goal is to have little pockets of cheese throughout the finished frittata.
Whisk 10 eggs in a bowl, then pour them evenly over the vegetables, sausage, and cheese.
Gently stir just enough to distribute the eggs throughout the pan.
Cover and cook over low heat.
After several minutes, gently stir or lift the mixture in one or two places to allow the uncooked egg to move toward the bottom. Be careful not to overmix or break up the mozzarella—you want to preserve those delicious little chunks of cheese rather than turn them into long strings.
Cover again and continue cooking until the eggs are mostly set.
Check occasionally. The center should be firm and the top should no longer look wet or runny.
For a more evenly cooked frittata, you can finish the dish in the oven.
After adding the eggs and gently mixing everything together, transfer the oven-safe skillet or Dutch oven to a 350°F oven.
Bake uncovered for approximately 15–25 minutes, depending on the depth of the frittata and the size of your pan.
The frittata is ready when the center is set and the top is lightly golden. A slight softness in the very center is fine—it will continue cooking from the residual heat after you remove it from the oven.
If you're using a Dutch oven, avoid making the frittata too deep. A wider, shallower vessel will cook the eggs more evenly.

Let the frittata rest for 5–10 minutes before slicing. Cut it into wedges, just like a pie, and serve warm.
The combination of tender potatoes, savory sausage, garden-fresh chard, and little pockets of mozzarella makes this a wonderfully satisfying meal any time of day.
This is one of those recipes that gets even more useful after the first meal.
Slice the cooled frittata into individual portions and refrigerate them for easy breakfasts and lunches throughout the week. You can also freeze individual slices for longer storage.
Reheat gently in the microwave, oven, or skillet. It's just as welcome on a busy weekday morning as it is fresh from the pan on a lazy weekend.
Thank you so much for stopping by and spending a little time with me here. I hope you find a recipe that brings a taste of Hungary to your kitchen and a few happy memories to your table.
