Ingredients You’ll Need

• 4 lb. russet potatoes, peeled and quartered
• 1 cup cooked beef sausage or smoked turkey sausage, finely chopped
• ¾ cup sour cream
• ⅓ cup unsalted butter
• 2 tablespoons heavy cream
• 2 cloves garlic, minced
• Kosher salt and ground black pepper
• 1 ¾ cups shredded sharp cheddar cheese, divided
• Chopped fresh chives, for garnish

Ingredient Tips & Substitutions

Potatoes: Russets are best for a light, fluffy mash. Want it creamier? Try Yukon Golds instead.

Sausage Swaps: Instead of traditional bacon, use finely chopped cooked beef or turkey sausage. Choose one with a smoky flavor for that classic “loaded” taste.

Cheese Options: Sharp cheddar gives this dish a deep, rich flavor. You can mix in mozzarella for a stretchier texture or use pepper jack if you like a little heat.

Cream Alternatives: Greek yogurt can replace sour cream for a tangier, protein-packed twist.

Dairy-Free Adaptations: Use dairy-free butter, sour cream, and shredded cheese if needed—just keep it creamy!

Step-by-Step Instructions

1. Boil the potatoes:
   Add peeled, quartered potatoes to a large pot. Cover with cold water and a pinch of salt. Boil until fork-tender, about 15–20 minutes. Drain and return to the pot.
2. Cook the sausage:
   While the potatoes boil, pan-fry the sausage in a skillet over medium heat until browned and crisp around the edges. Set aside on a paper towel-lined plate.
3. Mash and mix:
   Mash the hot potatoes until smooth. Stir in 1 ¼ cups cheddar, most of the sausage (save a little for topping), sour cream, butter, cream, garlic, salt, and pepper. Mix until creamy.
4. Assemble:
   Transfer the mashed mixture to a baking dish or oven-safe skillet. Sprinkle the top with the remaining cheese and sausage.
5. Bake:
   Bake at 350°F for about 15 minutes, or until the top is melted and golden.
6. Garnish and serve:
   Finish with chopped chives for color and freshness. Serve warm and enjoy!

Recipe Tips for Thanksgiving Success

Warm Your Dairy: Slightly warm the butter and cream before adding—this keeps the potatoes hot and smooth.

Make Ahead: Prep the whole casserole up to 2 days before. Refrigerate, then bake just before your feast.

Don’t Overmix: Over-mashing can turn your potatoes gummy. Stop once they’re creamy and combined.

Extra Flavor Boost: Add a sprinkle of smoked paprika or a pinch of dried thyme to enhance the holiday flavors.
