Crispy outside, soft inside, and a melty provola center—pure Italian comfort food.
These Spinach & Potato Cheese-Stuffed Balls are a classic “Nonna-style” appetizer made with mashed potatoes, sautéed spinach, eggs, and grated cheese, then stuffed with provola for that irresistible cheese pull.
Fry them for maximum crunch, or bake them for an easier, lighter option.

Cooking Times + Servings
Prep Time: 20 minutes
Cook Time: 15 minutes (fry) or 20–25 minutes (bake)
Total Time: 35–45 minutes
Servings: 6 (makes about 16–20 balls)
Ingredients
Boiled potatoes: 500 g (about 1.1 lb, ~3 medium potatoes), peeled
Spinach, sautéed and finely chopped: 350 g (about 12 oz)
Eggs: 2
Grated cheese (Parmigiano Reggiano or Pecorino): about 1/3 cup (a generous handful)
Breadcrumbs: 1/2 cup, plus more for coating
Olive oil: 1–2 tsp (to sauté spinach)
Salt & black pepper: to taste
Provola (or low-moisture mozzarella/fiordilatte): 6–8 oz, cut into small cubes
Optional (recommended):
Garlic: 1 clove (to sauté spinach)
Nutmeg: a pinch (great with spinach + cheese)
Instructions (Step-by-Step)
1) Cook and dry the spinach
Sauté spinach in a pan with a drizzle of olive oil (and garlic if using) until wilted and nice and dry.
Chop finely and let cool.
Tip: If there’s moisture, squeeze spinach in a clean towel—this prevents soggy balls.
2) Make the mixture
Mash boiled potatoes until smooth.
Add spinach, eggs, grated Parmigiano Reggiano, breadcrumbs, salt, pepper (and nutmeg if using).
Mix until you get a moldable dough.
Too soft? Add 1–2 tbsp breadcrumbs at a time.
Too dry? Add 1 tbsp beaten egg or a tiny splash of milk.
3) Stuff and shape
Scoop about 2 tbsp mixture and flatten slightly in your palm.
Place 1 cube of provola in the center.
Seal well and roll into a firm ball (no cracks!).
4) Coat with breadcrumbs
Roll each ball in breadcrumbs until fully coated.
Chill 10 minutes (optional but helps them stay perfect while cooking).
Cooking Methods
Option A: Fry (crispiest result)
Heat about 1 inch of oil in a skillet to 350°F.
Fry in batches, turning gently, 3–5 minutes until golden.
Drain on paper towels and season lightly with salt.
Option B: Bake (lighter + easy)
Preheat oven to 425°F.
Place balls on a parchment-lined baking sheet. Spray or drizzle lightly with oil.
Bake 20–25 minutes, turning once halfway, until golden and firm.
Option C: Air Fryer (super convenient)
Preheat to 390°F.
Lightly spray with oil.
Cook 10–12 minutes, turning once.
Tips & Tricks (Nonna-Style)
Squeeze spinach well—water is the enemy of crispy balls.
Seal tightly around the cheese, or it will leak during frying.
For extra crunch: do a double breadcrumb coat (dip in beaten egg, then breadcrumbs again).
FAQ
Why do my balls fall apart?
Too much moisture (spinach not squeezed) or not enough binder. Add breadcrumbs gradually and chill before cooking.
Can I prep them ahead?
Yes—shape and bread, then refrigerate up to 24 hours before cooking.
Can I freeze them?
Yes. Freeze uncooked, breaded balls on a tray, then transfer to a freezer bag. Cook from frozen:
Bake 25–30 minutes at 425°F, or air fry 12–15 minutes at 390°F.
What’s the best cheese for a stretchy center?
Provola is perfect. Low-moisture mozzarella works great too. Avoid watery fresh mozzarella unless well-drained.
Fry vs bake—what’s best?
Frying = crispiest and most traditional. Baking = easier and still delicious (use a little oil for browning).
