Your stress-free cooking guide for the perfect holiday feast
Christmas dinner doesn’t have to be chaotic or overwhelming. Whether you’re hosting a full house or cooking for a small gathering, this Christmas prep timeline walks you through exactly what to make and when, so your holiday meal comes together smoothly and without stress.
From desserts and breakfast casseroles to prime rib, lamb chops, and make-ahead sides, this guide helps you stay ahead and actually enjoy Christmas Day.
Two Days Before Christmas
Bake Your Desserts
Get your holiday sweets out of the way first. Cakes, cookies, and other baked treats stay fresh for days and free up your oven for the big items later on.
Pro Tip: Bake two days before Christmas, cool completely, and store in airtight containers.

Detailed Reheating Guide for Christmas Day
Greens
Stovetop: Medium heat, about 10–15 minutes, until the center reaches 165°F
Add a splash of broth or pot likker if needed to keep them moist.
Mac and Cheese
Oven: 350°F for about 25–35 minutes, until the center reaches 165°F
Add a little milk around the edges and cover with foil. Remove foil for the last 5 minutes if you want a crisp top.
Candied Yams
Oven: 350°F for about 25–30 minutes, until the center reaches 165°F
Cover with foil until heated through.
Mashed Potatoes
Stovetop: Stir occasionally and heat until the center reaches 165°F
Add butter, cream, or milk to restore creaminess.
Gravy
Stovetop: Reheat to a rolling boil. Whisk frequently until smooth and boiling. Add a splash of broth if it needs thinning.
Prime Rib Cooking Time Guide (325°F)
| Prime Rib Weight | Approx. Cook Time |
|---|---|
| 4–5 lbs | 1.5–2 hours |
| 6–7 lbs | 2–2.5 hours |
| 8–9 lbs | 2.5–3 hours |
| 10–11 lbs | 3–3.5 hours |
Always confirm doneness with a thermometer. USDA recommends cooking beef and lamb steaks, chops, and roasts to at least 145°F before removing them from the heat, followed by at least a 3-minute rest. The lower doneness temperatures listed below are below that recommendation; keep the longer 20-minute rest specified here.
Target internal temp:
- Rare: 120–125°F
- Medium Rare: 130–135°F
- Medium: 140–145°F
Rest meat at least 20 minutes before slicing.
Make-Ahead Storage Tips
Desserts:
Wrap tightly or store in airtight containers. Refrigerate or leave at room temperature depending on the dessert.
Mac & Cheese / Candied Yams:
Assemble, cover tightly with foil, and refrigerate up to 24 hours.
Prime Rib & Lamb Chops:
Season, wrap tightly, and refrigerate overnight.
Mashed Potatoes:
Store in a sealed container. Add a thin layer of melted butter on top to lock in moisture.
Gravy: Divide into shallow containers and refrigerate promptly at 40°F or colder, within 2 hours of cooking (1 hour above 90°F). Do not wait for gravy to cool completely on the counter.
FAQ: Christmas Prep Questions
Can I make Christmas desserts ahead of time?
Yes. Most cakes, cookies, and baked desserts can be made 2–3 days in advance.
How do I keep prime rib juicy?
Season ahead of time and cook using a thermometer. Resting the meat is just as important as cooking it properly.
What should I do if guests arrive early?
Have appetizers ready: deviled eggs, cheese boards, charcuterie, or a simple dip. It buys time and keeps things stress-free.
