Ingredients to Make Green Bean Smashed Potatoes:
- russet potatoes. Russet potatoes work best for a fluffy, starchy texture, but you can also use Yukon Gold or red potatoes if that’s what you have on hand.
- green beans. Fresh green beans provide the best flavor and texture, but frozen green beans can work in a pinch. If using frozen, adjust the cooking time as needed.
- onion. Adds a slight sweetness and depth of flavor. You can use yellow, white, or even shallots for a more delicate taste.
- butter. Gives richness and a creamy texture. Olive oil can be used as a substitute if you prefer a dairy-free or lighter option.
- heavy cream. Enhances creaminess, but you can swap it with milk or a dairy-free alternative if needed.

How to Make Green Bean Smashed Potatoes:
- In a large pot, melt 2 tablespoons of butter over medium heat. Add the diced onion to the melted butter 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 black pepper to the pot.
- Mash everything together, leaving some texture if desired. Taste and adjust the seasoning as needed before serving.

Recipe Notes & Tips:
- Sauté the Onion First: Cooking the onions in butter (or olive oil) before adding the potatoes deepens the flavor and ensures they’re perfectly soft and fragrant.
- Don’t Overcook the Green Beans: Adding the green beans along with the potatoes ensures they cook through but still retain some texture. If you prefer crisper green beans, add them during the last few minutes of boiling.
- Mash to Your Desired Texture: Keep it chunky for a rustic feel, or mash until smooth for a more traditional mashed potato texture.
- Customize the Flavor: Feel free to mix in cheese, fresh herbs, or roasted garlic for extra depth. A sprinkle of Parmesan or cheddar would work beautifully.
- Make It Dairy-Free: Swap the butter for olive oil and use coconut milk, almond milk, or another dairy-free alternative in place of the heavy cream.

Serving Suggestions:
- Tuscan Chicken
- Ground Beef Stroganoff
- Maple Roasted Ham
- Dijon Chicken
- Healthy Meatloaf
- Honey Mustard Chicken
How to Store:
Refrigeration: Store leftovers in an airtight container in the refrigerator for up to 3 days.
Reheating: Warm on the stovetop over low heat, adding a splash of cream or broth to maintain moisture. You can also microwave in 30-second intervals, stirring in between.
Freezing: While mashed potatoes can be frozen, the texture may change slightly. If freezing, store in an airtight container for up to 2 months and reheat with added butter or cream to restore creaminess.
FAQs:
Try adding roasted garlic, fresh herbs (like parsley or rosemary), or grated Parmesan cheese for extra depth.
Yes! If using Yukon Gold or red potatoes, you can leave the skins on for added texture and nutrients. If using russet potatoes, peeling them is recommended for a smoother texture.
Add the green beans during the last 5 minutes of cooking if you prefer them to have more bite.

Hi Michelle, I have not cooked this recipe in a crockpot, so I can’t guarantee success, but I can’t see why it wouldn’t work! If you try it, let me know how it turns out 🙂
