A Few Days Before Christmas (Make-Ahead Magic!):
For the Mashed Potatoes:
1. Prep Your Potatoes: Start by peeling and cutting your potatoes into roughly golf-ball-sized chunks. Keeping them even helps them cook uniformly.
2. Boil Them Tender: Place the potato chunks in a large pot, cover them with cold, salted water, and bring it to a rolling boil. Cook for about 15 minutes, or until they're super soft and easily pierced with a fork.
3. Mash It Up: Drain the potatoes very well. Now, mash them using a potato masher, a stand mixer, or even a ricer for the fluffiest results. Skip the food processor – it can make potatoes gluey!
4. Add the Goodness: While the potatoes are still warm, mix in the softened cream cheese (or Neufchâtel), sour cream (or Greek yogurt), milk (or 2% milk/broth), salt, and pepper. Stir until everything is smooth, creamy, and wonderfully blended. Taste and adjust the seasoning to perfection!
5. Store for Later: Transfer the mashed potatoes into a buttered casserole dish (for oven reheating) or the removable insert of your slow cooker. Cover it tightly and pop it in the fridge for up to three days.
For the Rich Make-Ahead Gravy:
1. Create Your Roux: In a medium saucepan, melt the butter (or dairy-free butter/olive oil) over medium-high heat. Whisk in the flour until it's smooth and fully combined.
2. Toast for Flavor: Continue whisking frequently for about 10 minutes until your roux turns a beautiful golden-brown color and smells slightly nutty. This deepens the flavor!
3. Slowly Add Stock: Gradually pour in the chicken stock (or your chosen stock), whisking constantly to keep any lumps from forming. Bring the gravy to a gentle simmer.
4. Thicken It Up: Let it cook for another 10–15 minutes, whisking occasionally, until it thickens enough to lightly coat the back of a spoon.
5. Season to Taste: Stir in the Worcestershire sauce (if using), salt, and pepper. Taste and adjust until it's just right.
6. Cool & Chill: Allow the gravy to cool completely. Then, pour it into an airtight container and refrigerate for up to three days (or freeze for longer storage).
On Christmas Day (Easy Reheating!):
To Reheat Mashed Potatoes:
Oven Method (Classic!): Take the dish out of the fridge about 30 minutes before baking to let it warm up slightly. Preheat your oven to 325°F (165°C). Cover the dish and bake for 35–50 minutes, or until it's hot and steamy throughout. Just before serving, dot the top with a little butter and sprinkle with fresh chives or green onions for a festive touch!
Slow Cooker Method (Hands-Off!): About 4–6 hours before your meal, transfer the chilled potatoes to your slow cooker. Set it to LOW, cover, and stir gently every couple of hours. If they look a bit dry, add 1-2 tablespoons of heavy cream (or milk/broth). Once heated through, switch to WARM until it's time to serve. Garnish with fresh herbs just before dishing up.
Pro Tip: For that irresistible "just mashed" taste, stir in a tablespoon or two of melted butter right before serving.
To Reheat Gravy:
1. Gentle Warm-Up: Transfer your refrigerated gravy to a saucepan and warm it gently over low heat, stirring occasionally to keep it silky smooth.
2. Add the Drippings: Once your Christmas roast is ready, pour the flavorful drippings into a fat separator (or carefully spoon off the fat from a measuring cup). Stir these incredible drippings right into your reheated gravy – it'll taste amazing!
3. Finish & Serve: Heat until everything is piping hot and glossy. Pour into your favorite gravy boat and serve immediately. Enjoy your perfectly smooth and rich Christmas gravy!
