Italian Green Beans and Potatoes is a comforting dish that even picky vegetable eaters tend to enjoy. Simple, hearty, and rooted in Italian-American tradition, this recipe’s secret is intentional overcooking—an old-school Italian approach that yields soft, flavorful vegetables.

This recipe brings back memories of summers in New Jersey where the family served these beans late in the season. Known to some as romano or pole beans, they’re larger, flatter, and meatier than typical green beans, making them ideal for longer cooking. My family simply called them Italian green beans, and we prepared them in a few classic ways: sautéed with lots of garlic and olive oil; sautéed with potatoes; or simmered with tomatoes, garlic and potatoes. Sometimes they were served at room temperature with a splash of vinegar.
What ties every version together is texture: these beans shine when allowed to become very tender. It’s not a modern “chef” approach, but for this dish, softer vegetables are part of the charm. Try the recipe and see for yourself.
String Beans vs. Green Beans vs. Italian Green Beans
Regular green beans can be hit-or-miss—often undercooked and under-seasoned. Italian green beans (romano or pole beans) differ in texture and shape: they’re thicker, wider, and heartier. Because of their size and structure, they tolerate longer cooking without falling apart, which is why we intentionally cook them until very soft. If you can’t find romano beans, regular green beans work well as a substitute.
Ingredients
For this Italian Green Beans and Potatoes recipe you’ll need:
- Romano (pole) beans or string/green beans: 1 1/4 pounds, ends trimmed and cut in half. Romano beans are larger and flatter; regular green beans are an acceptable substitute.
- All-purpose potatoes: 2 pounds, scrubbed and cut into 1″ chunks. Choose a low-starch, moist potato (red, white or Yukon Gold) so the pieces hold their shape when cooked.
- Olive oil: 4–6 tablespoons total. Use a basic olive oil for cooking and reserve a good extra-virgin olive oil for finishing the dish.
- Yellow onion: 1 medium, peeled and sliced.
- Garlic: 2 heaping tablespoons, chopped or thinly sliced.
- Crushed red pepper, salt and freshly ground black pepper to taste.

Step-By-Step, Pro-Tips included!
Overview of the method:
- Prep and measure ingredients. Rinse vegetables and scrub potatoes. Keep cut potatoes in cold water until ready to cook to prevent browning.
- Bring a large pot of water to a boil. Add salt once boiling, then add the beans. Boil until soft (about 5 minutes), then remove the beans and reserve the water for potatoes. Pro tip: add about 1 teaspoon salt per quart of water and add the salt after the water boils so it dissolves immediately.
- Return the pot to a boil and add the potatoes. Cook until tender (about 10 minutes). Reserve 1–2 cups of starchy potato water before discarding the rest.
- In a large sauté pan over medium-high heat, warm the olive oil. Add the sliced onion and cook until it begins to caramelize, about 10 minutes. Add the garlic and crushed red pepper and sauté another 1–2 minutes to release flavors.
- Add the cooked beans and potatoes to the pan with the onions and garlic. Mix and continue cooking until the vegetables reach your preferred tenderness. If needed, add some reserved starchy potato water to maintain moisture and cover the pan partially while cooking. Note: this recipe prefers overcooked, very soft vegetables.
- Season with salt and freshly ground black pepper. Finish with a drizzle of high-quality extra-virgin olive oil just before serving.
- Serve warm or at room temperature.








If you enjoy this dish, variations include adding tomatoes, mixing in cooked protein (chicken, sausage, meatballs), folding in fresh herbs like basil at the end, serving it chilled as a salad with a bit of white wine vinegar, or stirring in grated Pecorino Romano (reduce added salt if you do).
Frequently Asked Questions
Common questions:
Yes. Canned beans are already cooked, so skip the boiling step and proceed with the sauté. Frozen beans are blanched before freezing; defrost them and reduce or omit the initial boiling time—1–2 minutes may be enough.
Absolutely. Romano beans are seasonal and classic when available, but regular green beans work very well in this recipe.
Use a low-starch, high-moisture potato so the pieces hold together—red, white (thin-skinned), or Yukon Gold are ideal choices.
Recipe Variations for Green Beans and Potatoes
Popular ways to change the dish:
- Add tomatoes: After the garlic sautée, stir in 1–2 cups of chopped tomatoes and cook 5–10 minutes before folding in beans and potatoes.
- Boost protein: Fold in cooked chicken, sausage, or meatballs to make the dish a heartier main.
- Add fresh herbs: Finish with chopped basil and a drizzle of extra-virgin olive oil for brightness.
- Make it a salad: Mix in 2–3 teaspoons of white wine vinegar and serve at room temperature or chilled.
- Add cheese: Stir in about 1/3 cup grated Pecorino Romano before serving; reduce added salt accordingly.

Italian Green Beans and Potatoes
Ingredients
- 1 1/4 pounds string beans or romano beans, ends trimmed & beans cut in half
- 2 pounds all-purpose potatoes, rinsed, scrubbed and cut into 1″ chunks (store in cold water until cooking)
- 4–6 Tbsp olive oil (see note)
- 1 medium yellow onion, peeled and sliced
- 2 heaping Tbsp chopped or thinly sliced garlic
- Pinch crushed red pepper, salt and black pepper
Instructions
- Prep all vegetables as described above.
- Bring a large pot of water to a boil. Once boiling, add salt and the beans. Boil about 5 minutes or until soft. Remove the beans and set aside, keeping the water for the potatoes.
- Return the pot to a boil and add the potatoes. Cook about 10 minutes or until tender. Remove and set aside, reserving 1–2 cups of starchy potato water.
- While the vegetables boil, heat olive oil in a large sauté pan over medium-high heat. Add the onion and cook, stirring occasionally, until it begins to lightly caramelize (about 10 minutes). Add the garlic and crushed red pepper and cook 1–2 more minutes.
- Add the cooked beans and potatoes to the pan and mix well. Continue cooking until the vegetables are very soft, adding reserved potato water as needed and partially covering the pan for a brief time.
- Season with salt and black pepper. Finish with a drizzle of extra-virgin olive oil.
- Serve warm or at room temperature. Buon appetito!
Notes
- Keep cut potatoes submerged in cold water to prevent browning until ready to cook.
- Use about 1 teaspoon salt per quart of water and add it once the water boils so it dissolves immediately.
- Use a spider or large strainer to lift beans so the same water can be used for potatoes.
- Do not shock the green beans in ice water—this dish benefits from very soft, overcooked vegetables.
- Reserve 1–2 cups of starchy potato water to adjust moisture while finishing the dish.
- Add crushed red pepper with the garlic when sautéing to release its oils and flavor the dish more deeply.
- Finish with high-quality extra-virgin olive oil for added richness and flavor.
