👩‍🍳 Let’s Get Cooking!

Boil Those Beauties
Place cubed potatoes in a large stockpot or Dutch oven. Cover with cold salted water and bring to a boil. Reduce heat, cover, and simmer until tender—about 5 minutes. Drain and set aside.
Make the Creamy Dream Sauce
In a large saucepan, melt butter over medium heat. Add diced green onions and minced garlic; sauté until tender, about 3–4 minutes.
Thicken It Up
Whisk in the flour until lightly browned, about 1 minute. Gradually whisk in chicken stock and heavy cream. Let it simmer, stirring constantly, until thickened—around 5 minutes.
Cheese It, Please It
Remove from heat and stir in 3/4 cup cheddar cheese and the Dijon mustard. Fold in the potatoes. Season with salt and pepper to taste.
Bake & Broil
Preheat oven to 375°F. Spread the potato mixture into a greased 9×13 baking dish. Bake uncovered for 35–40 minutes until bubbly and tender.
Golden Glory Finish
Sprinkle the remaining cheese on top and broil for 2–3 minutes until golden and irresistible. Let rest for 5 minutes before serving.
Garnish for Glamour
Sprinkle with fresh chives for that pop of color and flavor
