About the Ingredients

2 lbs (900g) Yukon Gold potatoes, peeled and quartered

Yukon Golds are naturally buttery. Russets work too, but they need more cream.

1/2 cup (120ml) whole milk, warm

Whole milk adds richness. Use oat milk for dairy-free.

1/4 cup (60g) unsalted butter, melted

Salted butter is fine; just reduce added salt.

1 tsp salt, plus more for water

Kosher salt is best; adjust to taste.

1 lb (450g) fresh green beans, trimmed

Fresh beans give crispness. Frozen (thawed) can be used in a pinch.

1 can (10.5 oz/298g) condensed cream of mushroom soup

Use low-sodium if preferred. For homemade, see note.

1/2 cup (120ml) milk

Any milk works. Almond milk is fine.

1 1/2 cups (180g) crispy fried onions, divided

French's are classic. Use gluten-free if needed.

1/2 cup (60g) unsalted butter, plus 2 tbsp for greasing

Use vegan butter for dairy-free.

1 medium onion, diced

Yellow onion is sweet. Shallots work too.

2 celery stalks, diced

Adds classic stuffing flavor.

6 cups (420g) dried bread cubes (unseasoned)

Stale bread is ideal. Use gluten-free bread cubes if needed.

2 cups (480ml) low-sodium chicken or vegetable broth

Low-sodium lets you control salt. Homemade is best.

1 tsp dried sage

Sage is essential. Use 1 tbsp fresh if you have it.

1 tsp dried thyme

Thyme pairs well with sage. Rosemary can substitute.

Tips & Tricks

• Don't overwork the potatoes or they'll become gluey. Mash gently.
• Blanch the green beans to keep them bright green and crisp.
• Toast the bread cubes before making stuffing to prevent sogginess.

Step-by-Step Instructions

1. Preheat Oven

Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter.

2. Boil Potatoes

Place potatoes in a large pot, cover with cold salted water. Bring to a boil, then reduce to simmer. Cook until fork-tender, about 15-20 minutes. Drain well.

3. Mash Potatoes

Return potatoes to pot. Add warm milk and melted butter. Mash until smooth. Season with salt. Cover and keep warm.

4. Blanch Green Beans

Bring a large pot of salted water to a boil. Add green beans and cook for 3-4 minutes until bright green and crisp-tender. Drain and immediately plunge into ice water. Drain again and set aside.

5. Mix Casserole

In a large bowl, combine blanched beans, mushroom soup, milk, and 1 cup of fried onions. Stir until well coated. Transfer to one side of the prepared baking dish.

6. Sauté Aromatics

In a skillet, melt 1/2 cup butter over medium heat. Add onion and celery. Cook until softened, about 5 minutes. Remove from heat.

7. Prepare Stuffing

In a large bowl, combine bread cubes, sautéed vegetables, sage, and thyme. Pour broth over and stir gently. Let sit for 5 minutes to absorb.

8. Assemble Dish

Spoon stuffing onto the other side of the baking dish. Bake uncovered for 25 minutes. Then top green beans with remaining 1/2 cup fried onions and bake for another 10-15 minutes until golden and bubbly.

9. Rest and Serve

Let casserole rest for 5 minutes. Serve warm, with mashed potatoes on the side.

Delicious Variations

• Add crispy bacon bits to the green bean casserole.
• Mix in shredded cheddar cheese to the mashed potatoes.
• Use Italian sausage in the stuffing for extra flavor.
