Crispy around the edges, tender in the center, and packed with zucchini, sweet potato, butternut squash, spinach, feta, and sun-dried tomatoes. Served with a fresh lemon-herb yogurt, these make a delicious breakfast, brunch, lunch, or light dinner.

Ingredients

For the Rosti Muffins

2 medium zucchini, grated
1 large sweet potato, peeled and grated
1 cup butternut squash, finely grated
2 cups fresh spinach, chopped
½ cup crumbled feta cheese
⅓ cup sun-dried tomatoes, finely chopped
2 large eggs
¼ cup grated Parmesan cheese
2 tablespoons finely chopped fresh parsley
1 teaspoon dried oregano
½ teaspoon garlic powder
½ teaspoon onion powder
½ teaspoon smoked paprika
½ teaspoon salt
¼ teaspoon black pepper
2 tablespoons olive oil
3 tablespoons all-purpose flour or oat flour, optional, if the mixture needs additional binding

For the Lemon Herb Yogurt

1 cup plain Greek yogurt
1 tablespoon fresh lemon juice
1 teaspoon lemon zest
1 tablespoon chopped fresh parsley
1 tablespoon chopped fresh dill
½ teaspoon garlic powder
¼ teaspoon salt
Black pepper, to taste

Optional Garnish

Extra crumbled feta
Chopped parsley or dill
Thinly sliced sun-dried tomatoes
Lemon wedges
A drizzle of olive oil

Instructions

1. Prepare the Vegetables

Preheat the oven to 400°F (200°C).

Grate the zucchini, sweet potato, and butternut squash.

Place the grated zucchini in a clean kitchen towel and squeeze firmly to remove as much liquid as possible. Repeat with the sweet potato and butternut squash if they appear particularly wet.

This step is important because excess moisture can make the muffins soft and difficult to hold together.

2. Wilt the Spinach

Heat a large skillet over medium heat.

Add the chopped spinach and cook for about 1–2 minutes, just until wilted. Remove from the heat and allow it to cool slightly.

Squeeze out any excess moisture from the spinach.

3. Make the Rosti Mixture

In a large bowl, combine:

Grated zucchini
Grated sweet potato
Grated butternut squash
Spinach
Feta
Sun-dried tomatoes
Eggs
Parmesan
Parsley
Oregano
Garlic powder
Onion powder
Smoked paprika
Salt
Black pepper

Mix thoroughly until everything is evenly distributed.

If the mixture feels very loose or watery, add 2–3 tablespoons of flour or oat flour and mix again.

4. Fill the Muffin Tin

Grease a 12-cup muffin tin generously with olive oil or nonstick spray.

Divide the mixture evenly between the muffin cups, pressing it down firmly with the back of a spoon.

Fill each cup fairly well because the vegetables will shrink slightly while cooking.

Brush or drizzle a little olive oil over the tops.

5. Bake

Bake for 30–35 minutes, or until the muffins are golden brown around the edges and firm in the center.

For extra browning, switch the oven to broil/grill for the final 1–2 minutes, watching carefully so they don’t burn.

Remove from the oven and allow the muffins to rest in the pan for 5–10 minutes before removing them.

6. Make the Lemon Herb Yogurt

While the muffins are baking, combine the Greek yogurt, lemon juice, lemon zest, parsley, dill, garlic powder, salt, and black pepper.

Mix until smooth.

Taste and adjust the lemon, salt, or herbs as desired.

7. Serve

Place the warm rosti muffins on a serving plate.

Top with a spoonful of lemon-herb yogurt and garnish with:

Crumbled feta
Fresh herbs
Sun-dried tomatoes
A squeeze of lemon

Serve warm.

Cooking Tips

Squeeze the zucchini well: This is the most important step for preventing soggy rosti muffins.

Don’t skip the resting time: Letting them cool for several minutes helps them firm up and release more easily from the muffin tin.

Use a well-greased pan: The crispy vegetable edges can stick if the pan isn’t properly greased.

For extra crispy tops: Place the baked muffins under the broiler for 1–2 minutes.

For meal prep: Allow them to cool completely before refrigerating.

Storage

Refrigerator

Store cooled muffins in an airtight container for up to 4 days.

Keep the lemon-herb yogurt refrigerated separately.

Freezer

Freeze the completely cooled muffins in a freezer-safe container for up to 2 months.

Place parchment paper between layers to prevent sticking.

Reheating

Oven: 350°F (175°C) for 10–15 minutes
Air fryer: 350°F (175°C) for 5–7 minutes
Microwave: 30–60 seconds, although the edges won’t stay as crispy

Frequently Asked Questions

Can I make these without flour?

Yes. If the vegetables are squeezed very well and the eggs provide enough binding, you can leave out the flour. If the mixture seems too wet, adding a small amount of oat flour or another suitable binder can help.

Can I use frozen spinach?

Yes. Thaw it completely and squeeze out as much water as possible before adding it.

Can I use another cheese instead of feta?

Yes. Goat cheese, ricotta, mozzarella, or additional Parmesan can work. Feta provides the strongest salty, tangy flavor.

Can I use butternut squash without grating it?

Yes, but finely grated squash works best because it cooks quickly and blends into the rosti mixture.

Can I make these in an air fryer?

Yes. Form the mixture into compact muffin-sized portions or use silicone muffin cups. Air-fry at approximately 375°F (190°C) until golden and cooked through, checking them after about 12–15 minutes.

Why are my rosti muffins falling apart?

Usually this happens because the vegetables contain too much moisture or the muffins were removed from the pan too quickly. Squeeze the vegetables thoroughly and allow the muffins to rest for 5–10 minutes after baking.

Can I make them ahead?

Yes. Bake them completely, cool them, and refrigerate. Reheat them in the oven or air fryer for the best texture.

Are these gluten-free?

They can be. Simply use certified gluten-free oat flour if a binder is needed, or omit the flour if the mixture holds together without it.

Can I make them dairy-free?

Yes. Replace the feta and Parmesan with dairy-free alternatives and use a dairy-free yogurt for the sauce.

What can I serve with them?

They pair well with:

Lemon-herb Greek yogurt
Poached or fried eggs
Avocado
A green salad
Roasted vegetables
Grilled chicken
Smoked salmon

Can I make smaller bite-sized versions?

Yes. Use a mini muffin tin and reduce the baking time. They’re excellent as a brunch appetizer or party snack.

Can I make them more protein-rich?

Yes. Serve them with Greek yogurt, cottage cheese, eggs, or another protein-rich side. You can also increase the amount of feta or Parmesan slightly.

Can I make them without sun-dried tomatoes?

Absolutely. They can be omitted or replaced with chopped roasted red peppers, olives, fresh herbs, or caramelized onion.

Best Serving Idea

Serve 2–3 golden rosti muffins with a generous spoonful of lemon-herb yogurt, extra feta, fresh dill, and a squeeze of lemon. The combination of crispy vegetables, salty feta, sweet potato, tangy yogurt, and bright lemon makes a satisfying savory meal.
