This dish likely evolved from rustic Italian North American home cooking, where ‘dump and bake’ meals became popular in the 1970s and 80s for their minimal cleanup. It combines affordable proteins (chicken) with pantry staples (potatoes, canned or frozen green beans) and a fat source (butter or olive oil) to create a savory, tender meal.
The ‘Italian’ moniker comes primarily from the Italian herb seasoning used to coat the ingredients, rather than from traditional Italian culinary techniques. Dry herb blends became widely available in the mid-20th century, allowing home cooks to easily create Italian flavors without needing an extensive spice rack.
Soldiers returning from WWII brought home a taste for Italian flavors—specifically oregano on pizza—which paved the way for a market for Italian flavored products.
You generally won’t find this pre-mixed blend in Italy; Italian cooks typically use fresh herbs (like basil, parsley, or rosemary) individually or in regional combinations rather than a single ‘all-purpose’ dried mix.
The classic blend typically includes dried oregano, basil, thyme, rosemary, sage, and marjoram.
The Italian chicken, potato and green bean casserole is enjoyed for its ability to transform simple, humble ingredients into a comforting, nutritious, and versatile dish.

Ingredients

- Preheat the oven to 400 F.
- In a large mixing bowl, add the chicken, potatoes & green beans. Drizzle the olive oil over the ingredients in the bowl. Add Italian seasoning, garlic powder, onion powder, rosemary, basil, salt & pepper. Toss everything together until the chicken, potatoes & green beans are evenly coated with oil & seasoning.
- Transfer the mixture into a 9 x 13-inch baking dish, placing the chicken breasts in the center. Arrange the potatoes around the chicken & place the green beans on top. Cover the dish with aluminum foil (optional for a softer finish) or leave uncovered for a bit more crispiness.
- Bake for 35-40 minutes or until the chicken is cooked through & the potatoes are tender. If desired, sprinkle grated Parmesan cheese over the chicken & vegetables during the last 5 minutes of baking for a cheesy finish.
