Why You’ll Love This Recipe
Sweet Potato Rosti Muffins are a great choice when you want a savory vegetable dish that looks special but uses familiar ingredients. Sweet potato and butternut bring sweetness, zucchini keeps the centers tender, and feta adds a creamy, salty contrast.
The grated vegetables crisp around the edges, the spinach filling stays soft, and pine nuts add crunch. Sage brown butter gives the finished muffins a warm, nutty flavor.
How to Make Sweet Potato Rosti Muffins
Step 1: Preheat the Oven
Preheat the oven to 400°F or 200°C.
Grease a 12-cup muffin tin generously with olive oil or cooking spray.
Step 2: Prepare the Butternut Squash
Cut the butternut squash into very small cubes.
Spread them on a baking tray, drizzle lightly with olive oil, and roast for 12 to 15 minutes until just tender.
The squash will continue cooking inside Sweet Potato Rosti Muffins.
Step 3: Grate the Vegetables
Coarsely grate the sweet potatoes and zucchini using a box grater or food processor.
Transfer them to a clean kitchen towel.
Step 4: Remove Excess Moisture
Gather the towel around the vegetables and squeeze firmly over the sink.
Remove as much liquid as possible, especially from the zucchini. Excess moisture can make Sweet Potato Rosti Muffins soft instead of crisp.
Step 5: Prepare the Spinach
Heat olive oil in a skillet over medium heat.
Add spinach and cook for 1 to 2 minutes until wilted. Stir in garlic and cook for 30 seconds.
Cool slightly, then chop.
Step 6: Make the Spinach-Feta Filling
Combine the spinach with feta, parsley, and black pepper.
Mix gently and set aside.
Step 7: Mix the Rosti Base
Place the squeezed sweet potato and zucchini in a large bowl.
Add roasted butternut squash, eggs, Parmesan, feta, breadcrumbs, garlic powder, smoked paprika, thyme, salt, and black pepper.
Mix until evenly combined and the mixture holds together when pressed.
Step 8: Fill the Muffin Cups
Add a spoonful of rosti mixture to each muffin cup and press it into the bottom.
Place a small spoonful of spinach-feta filling in the center, then cover with more vegetable mixture and press gently.
Keeping Sweet Potato Rosti Muffins compact helps them hold their shape after baking.
Step 9: Bake Until Golden
Bake for 30 to 35 minutes, or until the tops and edges are deeply golden.
Step 10: Make the Sage Brown Butter
While the muffins bake, melt the butter in a small saucepan over medium-low heat.
Add sage leaves and cook until the butter turns golden brown and smells nutty, about 3 to 4 minutes.
Remove from heat and stir in honey, lemon juice, and salt.
Step 11: Cool Briefly
Let Sweet Potato Rosti Muffins rest in the tin for 5 to 8 minutes.
Run a thin knife around the edges if needed, then gently lift each muffin onto a platter.
Step 12: Add the Toppings
Spoon a little sage brown butter over each muffin.
Scatter toasted pine nuts and dried cranberries over the top.
Serve warm.
Serving Suggestions

Recipe Tips
Squeeze the grated zucchini very thoroughly because it holds a lot of water.
Grate the sweet potato coarsely so the edges become crisp.
Cut the butternut squash into small pieces so it cooks evenly.
Do not overfill the muffin cups.
Use block feta and crumble it yourself for better texture.
Toast the pine nuts before serving with Sweet Potato Rosti Muffins.
Let Sweet Potato Rosti Muffins rest before removing them from the pan so they keep their shape.
Add the sage brown butter just before serving.
Easy Variations
Sweet Potato Rosti Muffins can be customized with different vegetables, cheeses, and toppings.
Swap pine nuts for walnuts, pecans, pistachios, or pumpkin seeds.
Use goat cheese instead of feta for a softer, tangier filling.
Rosemary or extra thyme works well with the sage.
You can replace dried cranberries with chopped dried cherries or golden raisins.
For extra heat, add chili flakes, cayenne pepper, or a drizzle of hot honey.

Make-Ahead Instructions
Sweet Potato Rosti Muffins are excellent for meal prep because they reheat well.
Prepare the vegetable mixture and spinach filling one day ahead and refrigerate separately.
You can also bake the muffins, cool them.
Prepare the sage brown butter separately and reheat gently before serving.
Add pine nuts and cranberries after reheating so they stay fresh and crisp.
Storage and Reheating
Store leftover Sweet Potato Rosti Muffins in an airtight container in the refrigerator for up to 4 days.
Reheat in a 375°F or 190°C oven for 8 to 10 minutes. An air fryer also works well.
Microwaving is faster, but the outside will be softer.
For longer storage, freeze cooled muffins for up to 2 months. Thaw overnight in the refrigerator and reheat before serving.
