These Green Bean Smashed Potatoes combine tender potatoes, soft green beans, and sautéed onions mashed together with butter and cream for a simple, comforting side dish.
In a large pot, melt 2 tablespoons of butter over medium heat. Add the diced onion and sauté until softened and slightly caramelized.
Add the cubed potatoes and chopped green beans to the pot. Pour in enough water to cover the vegetables and add a pinch of salt.
Bring to a boil, then reduce to a simmer. Cook until the potatoes are fork-tender and the green beans are soft, about 15-20 minutes.
Carefully drain the water from the pot, leaving the potatoes, green beans, and onions. Add the remaining butter, heavy cream, garlic powder, salt, and pepper to the pot.
Mash everything together, leaving some texture if desired. Taste and adjust the seasoning as needed before serving.
