Zucchini Potato Recipe

Zucchini Potato — known in Italian as Zucchine e Patate — is a simple, wholesome dish that can be made three ways: oven-roasted into a golden gratin, pan-fried as a quick stir-fry, or baked in layers with cheese. Tender potatoes and mild, sweet zucchini come together with olive oil, garlic, and herbs into something that is far more delicious than the short ingredient list suggests. It is naturally vegetarian, easy to prepare, and works equally well as a hearty side dish or a light vegetarian main.

Ingredients
  

Group 1 — Core vegetables
  • 3 medium zucchini (courgettes about 400g; green, yellow, or both; thinly sliced into ¼-inch rounds
  • 4 medium potatoes about 500g; peeled and thinly sliced into ¼-inch rounds; Yukon Gold or waxy variety preferred
  • 1 tsp salt divided; adjust to taste
  • ½ tsp black pepper freshly ground
Group 2 — For the baked / gratin version
  • ½ cup breadcrumbs plain or seasoned panko for extra crunch
  • ½ cup grated Parmesan or Pecorino or Gruyère for a richer finish
  • 1 tbsp olive oil to drizzle over breadcrumb topping
  • ½ tsp garlic powder mix into breadcrumbs
Group 3 — Seasoning & base
  • 4 tbsp extra virgin olive oil use good quality; divided
  • 3-4 garlic cloves thinly sliced or minced
  • 1 tsp dried oregano or Italian herb mix
  • ½ tsp red chili flakes optional; adjust to heat preference
  • 2 tbsp resh parsley chopped; for garnish
  • 1 tbsp fresh basil leaves torn; optional, for Italian version

Equipment

  • 1 Large baking dish (9×13 inch) For the oven-roasted version
  • 1 Large skillet or frying pan For the stir-fry version
  • 1 Sharp knife and cutting board For even, uniform slices
  • 1 Mixing bowl For seasoning the vegetables
  • 1 Mandoline slicer (optional) For paper-thin, even potato slices
  • 1 Aluminum foil Optional, for covering while baking

Method
 

Group 1 — Prepare the vegetables
  1. Step 1 — Slice everything evenly
    Peel the potatoes and slice them into thin rounds, about ¼ inch (5–6 mm) thick. Slice the zucchini to the same thickness. Keeping the slices uniform is important — it ensures both vegetables cook at the same rate and nothing ends up undercooked or mushy.
  2. Step 2 — Season the vegetables
    Place the potato slices and zucchini slices in a large mixing bowl. Add 3 tablespoons of olive oil, salt, black pepper, garlic, oregano, and red chili flakes if using. Toss well to coat every slice evenly. Let them sit for 5 minutes to absorb the seasoning.
Group 2 — Oven-roasted method (Italian style)
  1. Step 3 — Preheat the oven
    Preheat your oven to 200°C (400°F). Lightly grease a 9×13 inch baking dish with olive oil.
  2. Step 4 — Layer the vegetables
    Arrange the seasoned potato and zucchini slices in alternating overlapping layers in the baking dish — a potato slice, then a zucchini slice, slightly overlapping like roof tiles. Continue until all slices are used. Drizzle any remaining seasoning oil from the bowl over the top.
  3. Step 5 — Add the breadcrumb topping
    In a small bowl, mix the breadcrumbs, grated Parmesan, garlic powder, and 1 tablespoon of olive oil until the mixture resembles damp sand. Scatter this evenly over the layered vegetables.
  4. Step 6 — Bake until golden
    Place the dish in the preheated oven and bake uncovered for 38–42 minutes, until the potatoes are completely tender when pierced with a knife and the breadcrumb topping is deep golden brown and crisp. If the top browns too quickly, loosely cover with foil for the last 10 minutes. Rest for 5 minutes before serving.
Group 3 — Quick pan stir-fry method (everyday version)
  1. Step 7 — Cook the potatoes first
    Heat 2 tablespoons of oil in a large skillet or frying pan over medium heat. Add the potato cubes or slices and a pinch of salt. Cook, stirring occasionally, for 8–10 minutes until the potatoes are almost fully cooked through and lightly golden on the edges.
  2. Step 8 — Add the zucchini
    Add the sliced zucchini to the pan with the partially cooked potatoes. Stir to combine. Cook on medium heat for a further 6–7 minutes, stirring occasionally, until the zucchini is tender but still holds its shape and is lightly golden on the edges.
  3. Step 9 — Season and finish
    Add the garlic, red chili flakes, oregano, salt, and pepper. Stir and cook for 2 more minutes until the garlic is fragrant and everything is well coated. Taste and adjust seasoning. Remove from heat, garnish with fresh parsley or basil, and serve immediately.

Notes

  • Two recipes in one: This post covers both the oven-roasted Italian gratin version (zucchine e patate al forno) and the quick pan stir-fry version. Choose whichever suits your time and mood — both use the same base ingredients.
  • Best potatoes to use: Waxy varieties like Yukon Gold, red potatoes, or new potatoes hold their shape during baking. Starchy potatoes like Russet will turn softer and creamier — also delicious, but a different texture.
  • Slice thickness matters: Cut both the potato and zucchini to the same thickness so they cook evenly. A mandoline slicer makes this effortless, but a sharp knife works fine.
  • Don't skip the resting time: After baking, resting the dish for 5 minutes allows the layers to settle and makes serving much neater.
  • Add cheese inside the layers: For a richer gratin, scatter grated Parmesan or Gruyère between the layers as well as on top. Mozzarella also works beautifully for a stretchy, melted texture.
  • Make it vegan: Simply omit the cheese from the topping and use plain breadcrumbs with olive oil. The dish is still deeply flavorful and satisfying.
  • Summer vegetable additions: Thinly sliced tomatoes, bell peppers, or eggplant can be layered in alongside the zucchini and potato for a full summer vegetable gratin.
  • Leftovers: Store in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 180°C (350°F) for 10–12 minutes to restore the crisp topping. Avoid microwave reheating — it softens the breadcrumb crust.
  • Serving suggestions: Serve as a side dish alongside grilled chicken, fish, or a simple green salad. For a vegetarian main, pair with crusty bread and a bowl of soup.
