Yield
12 mini quiche cups
Ingredients
For the Rosti Cups
2 medium sweet potatoes, about 1½ lb (680 g), peeled
1 medium zucchini
1 tablespoon olive oil
½ teaspoon salt
¼ teaspoon black pepper
½ teaspoon garlic powder
½ teaspoon dried thyme
For the Quiche Filling
5 large eggs
½ cup (120 ml) milk or half-and-half
½ cup crumbled feta cheese
¼ cup grated Parmesan cheese
2 tablespoons fresh thyme leaves
¼ teaspoon salt
¼ teaspoon black pepper
¼ teaspoon garlic powder
2 tablespoons finely chopped green onions
¼ cup finely chopped roasted red pepper — optional
For the Honey-Thyme Finish
1½ tablespoons honey
1 teaspoon fresh thyme leaves
1 teaspoon olive oil
Pinch of black pepper
Instructions
- Preheat the Oven
Preheat oven to 400°F (200°C).
Generously grease a 12-cup muffin pan with olive oil or nonstick cooking spray.
For especially easy removal, you can use silicone muffin cups.
- Prepare the Sweet Potato
Coarsely grate the peeled sweet potatoes.
Place them in a clean kitchen towel and squeeze firmly to remove as much moisture as possible.
This step is important because excess moisture can prevent the rosti cups from becoming crisp.
- Prepare the Zucchini
Grate the zucchini and place it in another clean towel.
Squeeze out as much liquid as possible.
Add the sweet potato and zucchini to a large bowl.
Add:
Olive oil
Salt
Black pepper
Garlic powder
Thyme
Mix thoroughly.
- Form the Rosti Cups
Divide the vegetable mixture evenly among the 12 muffin cups.
Press the mixture firmly into the bottom and up the sides of each cup, creating a small nest.
Make the sides slightly thicker than the bottom so the cups hold their shape.
- Pre-Bake the Rosti Shells
Bake for 15–18 minutes, until the edges begin turning golden and crisp.
Remove from the oven.
Reduce the oven temperature to 375°F (190°C).
- Prepare the Quiche Filling
In a bowl, whisk together:
Eggs
Milk or half-and-half
Feta
Parmesan
Fresh thyme
Salt
Black pepper
Garlic powder
Green onions
Roasted red pepper, if using
Whisk until well combined.
- Fill the Cups
Carefully pour the egg mixture into each partially baked rosti cup.
Fill each cup about ¾ full.
Don’t overfill because the eggs will puff slightly as they bake.
- Bake the Mini Quiches
Return the muffin pan to the oven.
Bake for 15–18 minutes, or until:
The eggs are set in the center
The tops are lightly golden
The rosti edges are crisp
Avoid overbaking, as the egg filling can become rubbery.
- Make the Honey-Thyme Drizzle
While the quiche cups are baking, combine:
Honey
Fresh thyme
Olive oil
Black pepper
Mix well.
For easier drizzling, warm the honey very slightly if it is thick.
- Rest and Remove
Allow the quiche cups to cool in the pan for 5–10 minutes.
Run a thin spatula or butter knife carefully around the edges and gently lift them out.
Drizzle lightly with the honey-thyme mixture.
Finish with a little extra feta and fresh thyme if desired.
Optional Toppings
Try finishing the mini quiches with:
Extra crumbled feta
Fresh thyme
Fresh parsley
Chili flakes
Balsamic glaze
Toasted pumpkin seeds
Avocado
Microgreens
A tiny drizzle of hot honey
ALL NUT INFO & ALLERGEN INFORMATION
Does this recipe contain nuts?

Possible allergens
Milk/Dairy: feta, Parmesan, milk or half-and-half
Eggs: eggs are a primary ingredient
Honey: used in the finishing drizzle
Nuts: not present in the basic recipe
Pumpkin seeds
If you use pumpkin seeds as a topping, they are seeds, not tree nuts, but people with seed allergies should avoid them.
How to make it nut-free
The recipe is naturally nut-free as written. Check packaged ingredients such as Parmesan, feta, cooking spray, and seasonings if preparing the recipe for someone with a serious allergy.
How to make it dairy-free

How to make it gluten-free
The recipe is naturally gluten-free when all packaged ingredients are verified gluten-free and there is no cross-contact during preparation.
Vegan option
This recipe is not easily vegan because eggs are central to the quiche filling. A plant-based egg substitute can be used, although the texture will be different.
Important Tips for Crispy Rosti Cups
- Squeeze the vegetables well
This is the most important step. Zucchini and sweet potato release moisture, and too much moisture can make the cups soft.
- Don’t skip the pre-bake
Pre-baking allows the potato-zucchini shells to firm up before the egg mixture is added.
- Grease the muffin pan well
The crispy edges can stick if the pan isn’t properly greased.
- Don’t overfill
Leave some room at the top for the egg mixture to expand.
- Let them rest
Allowing the cups to cool for several minutes makes them much easier to remove without breaking.
Storage
Store cooled quiche cups in an airtight container in the refrigerator for up to 3–4 days.
Place parchment paper between layers if stacking them.
Reheating
Reheat in:
Oven: 350°F (175°C) for about 8–10 minutes
Air fryer: 325°F (165°C) for about 4–6 minutes
Microwave: 30–60 seconds, although the rosti exterior will be softer.
For the crispiest texture, use the oven or air fryer.
Can You Freeze Them?
Yes.
Allow the quiche cups to cool completely, then place them in a freezer-safe container or bag with parchment between layers.
Freeze for up to 2 months for best quality.
Thaw overnight in the refrigerator and reheat in the oven or air fryer.

Q&A
Q: Can I make these ahead of time?
A: Yes. Bake them completely, refrigerate, and reheat before serving. They are excellent for meal prep.
Q: Why are my rosti cups soggy?
A: The most common reason is excess moisture. Squeeze the grated zucchini and sweet potato very well before forming the cups.
Q: Can I use regular potatoes instead of sweet potatoes?
A: Yes. Russet or Yukon Gold potatoes work well, although the flavor will be less sweet.
Q: Can I use frozen shredded sweet potato?
A: Yes, but thaw it completely and squeeze out as much moisture as possible before using.
Q: Can I use shredded mozzarella instead of feta?
A: Yes. Mozzarella will give you a milder, more melty filling. Feta provides a stronger salty contrast to the sweet potato and honey.
Q: Can I skip the honey?
A: Absolutely. The honey-thyme drizzle is optional. The quiche cups are delicious without it.
Q: Can I make these spicy?
A: Yes. Add red pepper flakes, diced jalapeño, or a little hot honey to the filling or topping.
Q: Can I add spinach?
A: Yes. Finely chop the spinach and squeeze out excess moisture before adding it to the egg mixture.
Q: Can I add bacon?
A: Yes. Cook the bacon first, drain well, crumble it, and add it to the egg filling.
Q: Can I make them without Parmesan?
A: Yes. Simply omit the Parmesan or replace it with additional feta.
Q: Can I use a mini muffin pan?
A: Yes, but you’ll need to reduce the baking time because the cups will be smaller. Watch them closely during both the rosti and egg-baking stages.
Q: How do I stop the cups from sticking?
A: Grease the muffin pan generously, especially around the sides. Let the cups rest for 5–10 minutes after baking before removing them.
Q: Are these good for meal prep?
A: Yes. They refrigerate well for 3–4 days and can be reheated in an oven or air fryer.
Q: Can I freeze them?
A: Yes. Cool completely, wrap well, and freeze for up to about 2 months for best quality.
Q: Can I make the rosti cups separately?
A: Yes. You can pre-bake the sweet potato-zucchini shells and refrigerate them for up to a day before adding the egg filling and finishing the recipe.
Q: What makes these “Caprese” or Mediterranean-style?
A: These particular cups are Mediterranean-inspired rather than a traditional classic dish. The combination of feta, olive oil, thyme, vegetables, and honey gives them a Mediterranean flavor profile.
