Thanksgiving Timeline

There are steps you can take in the weeks leading up to Thanksgiving that will help you to stay organized. With a preparation timeline in place, serving 100 guests on the day of the holiday will be a smooth operation.

1 Month Before Thanksgiving

  • Guest count. Request a final guest count from your clients.
  • Finalize your menu. Choose your recipes and get your menu approved by your client. It is here where you can decide to branch out and propose unique ideas such as smoking turkey rather than roasting it. If you have more or fewer people attending than expected, you can use our recipe resizer to convert your favorite recipes to a larger or smaller yield.
  • Ensure that you have adequate kitchen space. Once you know how many guests to expect and how much food you need to prepare, make sure you have the kitchen space required. If your commercial kitchen isn't suitable for such a large event, consider renting a larger kitchen space or a mobile food trailer.
  • Order your turkeys. Save time and money by ordering turkeys in advance from a bulk supplier.

2 Weeks Before Thanksgiving

  • Acquire your serving dishes. Choose the correct size serving pans or chafing dishes for your dinner service. If you want to minimize cleanup time, try disposable aluminum food pans.
    • Plate of cooked turkey.
  • Gather your serving utensils. Designate serving utensils for each dish. A shortage of serving utensils could slow down your guest line if you're having a buffet-style Thanksgiving dinner.
  • Create a shopping list. Create a list of all your ingredients and make note of which items are non-perishable versus which items are fresh.
  • Make room for refrigerated foods. Inspect your refrigeration equipment and ensure adequate room for all of your ingredients and prepared dishes. You may need room for several large turkeys, so keep that in mind.

1 Week Before Thanksgiving

  • Start food shopping. Order all the non-perishable ingredients on your shopping list.
  • Stock up on take-out containers. Ensure you have enough take-out containers to allow guests to take leftovers home.
  • Create a plan for Thanksgiving Day. Make a timeline that includes specific start times for food prep, cooking, and serving. Share your plan with all staff members assisting with the event.
  • Start making side dishes. This is a great time to make pie crusts and dinner rolls. Put them in the freezer until later in the week.
  • Start defrosting turkeys. If you have purchased frozen turkeys, start defrosting them now. A turkey needs 24 hours for every 4 to 5 pounds to defrost. Always defrost frozen poultry inside your reach-in or walk-in cooler.
  • Pick up the turkeys you ordered. If you ordered fresh turkeys ahead of time, pick them up from your local farm or grocer.

Monday Before Thanksgiving

  • Shop for all fresh ingredients. Buy fresh ingredients and any other last-minute items you need.
  • Prepare stuffing ingredients. If you are making stuffing from scratch, cube day-old bread loaves and simmer a large pot of fresh stock.

Tuesday Before Thanksgiving

  • Prepare brining liquid. If you are brining your turkeys, gather the dry ingredients for your brine and combine them. You can brine a turkey for a few hours or up to 2 days, depending on the concentration of seasonings in your brine. Use a more diluted mixture to brine over a few days or a concentrated mixture for 8 to 12 hours.
  • Defrost any frozen dishes. Move dinner rolls, pie crusts, or any frozen dishes from the freezer to the refrigerator.
  • Make cranberry sauce. Because of its high acidity, cranberry sauce has a long fridge life. Put this dish together and store it in the refrigerator until Thursday.

Thanksgiving Eve

  • Make pies. Bake pies and put them aside in the fridge. By making pies on Wednesday, you'll free up oven space and preparation time on Thanksgiving Day.
  • Make green bean casserole. Prepare green beans and their sauce, but reserve the topping until Thanksgiving Day so it doesn't get soggy.
  • Make stuffing and mashed potatoes. If you have time, prepare your various potatoes and stuffing simultaneously so you can devote most of your cooking time to the turkeys the next day.
  • Label serving utensils and dishes. All staff members will know which utensils and dishes to use if they are labeled.
  • Set up buffet and tables. If you have access to your venue ahead of time, set up your space for dinner the next day.

Thanksgiving Day

  • Begin cooking turkeys. Remember that a minimum internal temperature of 165 degrees Fahrenheit is required for turkey to prevent foodborne illness. Take the temperature reading from the thigh meat to ensure the turkey is thoroughly cooked.
  • Bring dishes to room temperature. Remove your rolls, sides, and pies that do not require chilling from the fridge.
    • What temperature to cook turkey?
  • Let cooked turkeys rest. Once cooked, it's best to let your turkeys rest for 15-20 minutes before carving. Resting the meat will keep it from drying out.
  • Re-heat sides. While the turkeys are resting, put the side dishes in the oven to warm them before serving.
  • Make gravy. When the turkeys are cooked, start making gravy from their drippings.
  • Transfer everything to serving dishes. Move everything to the serving dishes you designated earlier.
  • Set out toppings and sauces. Place toppings and sauces like various butters, gravy, and cranberry sauce out, allowing guests to top their dishes how they see fit.
  • Uncork wine bottles. Open up and set out some bottles of wine or other alcohol to pair with your delicious Thanksgiving meal.
  • Set up supplies for coffee and tea. Putting these aside before dinner will help your beverage service go much faster once dinner is over.

How to Serve Thanksgiving Dinner

Now that you know how to make Thanksgiving dinner for a crowd, here are some tips for serving your holiday menu.

Buffet or Plated?

Dinner buffets are considered casual, while a plated dinner is more formal. Also, consider that plating every dish requires more work ahead of time, but it allows you to control portions. Buffets are less work in the kitchen and provide more freedom for each guest.

Buffet Lineup

The position of a dish at your buffet can impact the portion size that your guests choose. Placing the turkey at the beginning of your buffet line encourages guests to take larger portions. If you place the turkey at the end of the table, their plates will already be full and they'll take less. If you have any dishes that may run out, try placing them at the end of the buffet.

Keeping Dishes Warm

Keeping all of your dishes at food-safe temperatures is crucial for safety. Chafing dishes or steam tables can be used to keep hot foods hot. Monitor the temperatures of all displayed foods every 2 hours to ensure they meet the minimum temperature required for food safety.

When making Thanksgiving dinner for a crowd, the key to success is planning ahead. This month, refer to our table for serving suggestions and follow our Thanksgiving checklist and timeline to stay on track.

This sweet potato gratin recipe combines the Hasselback slicing method with a cheesy, garlicky topping to create a new twist on potatoes au gratin. It's a comforting dish that will look beautiful on your holiday table or any time of the year you crave sweet potatoes! Jump to Recipe What Are Hasselback Potatoes? Hasselback potatoes are prepared with a unique slicing method that creates a fan-like shape. It makes an attractive presentation, and it allows the thinly sliced potato to cook up evenly and absorb ingredients. To make Hasselback potatoes, start with a freshly washed potato and make deep slices about 1/8" to 1/4" wide. The key is to stop slicing before you cut all the way through and leave the bottom of the potato uncut. Once all the slices are made, the potato will fan out. Top the potato with seasonings, butter, or cheese and bake it in the oven just like a regular baked potato. Or try our Hasselback sweet potato gratin recipe below! Why Is it Called a Hasselback Potato? Hasselback potatoes get their name from a Swedish restaurant called Hasselbacken. The first Hasselback potatoes were introduced at Hasselbacken in the 1940s.

Manchego cheese is a Spanish cheese made from sheep's milk. If you can't locate Manchego, you can subsitute with gouda or mild cheddar cheese. Make it Vegan You can make this dish completely vegan with a few substitutions. Use a plant-based butter like Earth Balance instead of the butter. In place of the heavy cream, use unsweetened coconut milk from a can. Skip the cheese topping entirely, or use your favorite melting vegan cheese.

  • How to Deep Fry a Turkey

    Deep frying a turkey is a delicious and flavorful way to prepare this classic holiday centerpiece. The process involves immersing a whole turkey in hot oil, resulting in a crispy, golden-brown skin and tender, juicy meat. While deep frying may seem intimidating, with the right equipment and precautions, it can be a safe and rewarding way to prepare a turkey. We'll walk you through the process of frying a whole turkey so you can add a new cooking method to your arsenal. Shop Outdoor Fryers Deep Fried Turkey Ready to get started? Check out our video to learn how to deep fry a turkey with a turkey fryer kit: <iframe scrolling="no" src="/v/?num=3679&amp;width=600&amp;height=500&amp;embed=1" frameborder="0" height="500" width="600"></iframe> How Long Does it Take to Deep Fry a Turkey? Generally, it is recommended to deep fry a turkey for about 3 1/2 to 4 minutes per pound. So, for example, if you have a 15-pound turkey, it would take approximately 52 to 60 minutes to cook it through. However, it's important to note that this is just a rough estimate and you should always use a meat thermometer to ensure that the turkey is cooked to a safe internal temperature of 165°F. One of the main benefits of deep frying a turkey is the speed at which it cooks. Unlike traditional roasting methods that can take several hours, deep frying can produce a fully cooked turkey in just a fraction of the time. This is especially helpful when you have a large group of hungry guests eagerly awaiting their holiday feast. Check out these general cook times for deep frying a whole turkey: 10 pounds - 35 to 40 minutes 12 pounds - 42 to 48 minutes 14 pounds - 49 to 56 minutes 16 pounds - 56 to 64 minutes 18 pounds - 63 to 72 minutes 20 pounds - 70 to 80 minutes What Special Equipment Do I Need? Before you get started, you'll need to gather the following materials: Turkey, completely defrosted with giblets removed Frying oil Dry rub or marinade Turkey fryer, which should include a stock pot, rack, stand, propane tank, skewers, probe thermometer, and injector Paper towels Kitchen shears Oil thermometer Gloves, goggles, long-sleeved clothing Fire extinguisher Learn more about choosing the right oil in our turkey fryer oil resource. Deep Fried Turkey Recipe Follow our step-by-step instructions to deep fry a whole turkey. Make sure to read all safety recommendations included in your turkey fryer manual. Keep a fire extinguisher on hand in case of an emergency. 1.Set up the turkey fryer kit and turn on the burner, but keep the flame low. Fill the cooking pot with the correct amount of oil and place it on the burner. Now, turn up the flame to start heating the oil. 2.Attach an oil thermometer to the side of the pot and preheat the oil to 350 degrees Fahrenheit. Submerge the tip of the thermometer but don't let it touch the wall of the pot. 3.While the oil is preheating, start prepping the turkey. Pat down the fully defrosted bird with paper towels to remove any excess moisture. 4.Using kitchen shears, remove excess fat and cut slits in the front of each leg. 5.Using dry rub, marinade, or a combination of both, add seasonings to the turkey. You can also try injecting the turkey with marinade to lock in the flavor. 6.Place the turkey on the lifter and attach the hook. Remove the thermometer from the fryer before lowering the turkey into the pot. Re-attach the thermometer to the pot once the turkey is lowered in. 7.Put on safety gloves, apron, and goggles. Lower the turkey inch-by-inch into the pot, making sure to go very slowly. You should be going so slow that it will take about a minute to get the bird fully inserted into the oil. This will help to prevent boil-over or splashing. 8.Once the turkey is fully submerged, deep fry it for about 3 1/2 to 4 minutes per pound. 9.Slowly remove the turkey from the fryer, letting any extra oil drain from the cavity. 10.Check the temperature of the turkey using a probe thermometer. Its internal temperature should be at least 165 degrees Fahrenheit. When you’re finished, place the turkey in a pan or on paper towels. Just like you would rest a steak, rest the cooked turkey for 20-45 minutes to ensure it reabsorbs its juices. Check out our turkey carving tutorial to learn how to cut up your fried turkey the easiest way. Turkey Fryer Safety Tips Without the right preparation, deep frying a turkey does come with potential hazards. Follow our safety suggestions to help prevent fires, combustion, and oil spills. Completely Thaw the Turkey - If the turkey isn't completely thawed, the oil could boil over and start a fire. Always defrost the turkey using a food-safe method. Remove all giblets and drain the cavity before frying. If water or slush is left behind, the oil may bubble or splash when the turkey is placed in the pot. Don't Stuff the Turkey - Stuffing a turkey before cooking has the potential to cause cross-contamination. Set Up the Fryer in a Safe Place - Always make sure the fryer is on a flat surface that’s far from any flammable objects, such as wood decks, trees, and buildings. Check the Internal Temperature - The internal temperature of a fried turkey must be a minimum of 165 degrees Fahrenheit. Handle the Fryer Oil Safely - Adding too much oil to your fryer can lead to spillovers. Also, choose an oil with a high smoke point so that it doesn't overheat. Wear PPE - Wear protective clothing, including gloves, goggles, and long-sleeved shirts.
