How to Thaw a Turkey Properly

If you’re starting with a frozen turkey, it’s important to plan ahead. The safest way to thaw it is in the refrigerator. Allow roughly 24 hours of thawing time for every 4–5 pounds of turkey. That means a 15–20 pound bird will take about 3–5 days to fully thaw.

Keep the turkey in its original packaging, placed on a tray to catch any juices, and let it thaw slowly in the fridge. Never thaw your turkey at room temperature, as this can cause uneven thawing and potential bacterial growth.

Once thawed, let the bird sit at room temperature for 30–45 minutes before cooking—this ensures even heat distribution and a more consistent cooking time.

How Much Turkey to Serve Per Person

When planning your thanksgiving turkey, aim for about 1 to 1½ pounds of turkey per person. This accounts for the bones and ensures everyone gets enough juicy meat—plus some leftovers for sandwiches or soup.

For example, a whole turkey weighing 15 pounds will comfortably feed 10–12 people. If you love leftovers (and who doesn’t?), go for a slightly larger bird so you’ll have plenty of that smoked turkey flavor to enjoy later.

Below is a guide on what size turkey you will need for your party. Consider cooking two smaller turkeys for larger gatherings, this will reduce overall cook time and likely result in a better outcome. 

4-8 people you need a 8-12 pounds of turkey.

8-11 people, you need 12-16 pounds of turkey. 

11-13 people, you need 20-24 pounds of turkey

16-19 people, you need 24-28 pounds of turkey. 

Note: the measurements above are total turkey weight, not pounds of carved meat needed.

Ingredients You’ll Need for Smoked Turkey with Cajun Butter

• 1 (15–20 pound) fresh turkey
• 3 tbsp SPG Blend Seasoning
• 1 tbsp cajun seasoning

Cajun Butter Injection:

• 16 tbsp unsalted butter
• 3 tbsp cajun seasoning
• 1 tbsp kosher salt
• 1 tbsp garlic powder
• ½ tbsp black pepper
• ¼ cup brown sugar
• Juice from 1 lemon
• ⅓ cup chicken stock

How to Make the Cajun Butter Injection

In a small saucepan, combine all the cajun butter injection ingredients and melt them together over medium heat. Stir well so the butter, seasonings, and chicken stock combine into a smooth mixture.

This cajun butter injection will add rich bold flavor and help keep the juicy turkey tender from the inside out.

The secret to this great turkey recipe is using a meat injector to layer flavor throughout the entire bird—ensuring every bite is packed with buttery spice and juicy meat.

Preparing the Turkey

Start by patting your fresh turkey dry with paper towels. Removing excess moisture helps achieve that crispy skin during smoking.

Next, spatchcock the turkey by cutting down the backbone with sharp kitchen shears.

Remove the spine, flip the bird, and press down firmly to flatten it. This ensures more even cooking and shorter cooking time.

Once prepped, use your meat injector to inject the cajun butter injection throughout the turkey. Be sure to inject into the thickest part of the breast, thighs, and drumsticks.

Rub a light layer of melted butter over the top of the turkey and season the outside with kosher salt, black pepper, garlic powder, and a light dusting of creole seasoning or cajun rub.

This step adds an extra punch of cajun flavor and helps create that irresistible golden crust once the turkey is smoked.

Smoking the Turkey

Place turkey on your smoker preheated to 350°F. Use a roasting pan or wire rack to elevate it slightly and allow airflow beneath the whole turkey.

Smoke the turkey for a couple of hours (about 2–2.5 hours total) until an instant read thermometer or meat thermometer inserted into the thickest part of the breast reads 165°F.

Once it hits temperature, tent the top of the turkey loosely with aluminum foil and let it rest for at least 20 minutes on a cutting board before carving with a sharp knife.

This resting time allows the juices to redistribute through the entire bird, ensuring perfectly juicy turkey in every slice.

Tips for the Best Cajun Butter Turkey

• Use room temperature butter: It mixes easier and distributes more evenly for a smooth cajun injection.
• Don’t skip the rest: Letting the turkey rest before slicing keeps the juices locked in.
• Layer flavor: Between the cajun butter injection, creole seasoning, and sweet smoke flavor. This method ensures your turkey has rich depth and complexity.
• Monitor temperature closely: Always rely on an instant read thermometer to prevent overcooking.
• A splash of hot sauce in the butter mixture gives it a nice kick without overwhelming the bold flavor.

Serving Your Smoked Cajun Butter Turkey

Once rested, carve your thanksgiving turkey by slicing through the thickest part of the breast and separating the thighs and drumsticks. Arrange the meat on a platter and drizzle any extra melted cajun butter over the top for added richness.

The best part of this recipe is how the smoky, buttery, and spicy flavors come together in harmony. Every bite of this smoked turkey delivers juicy meat, crispy skin, and that signature cajun flavor that keeps everyone coming back for seconds.

Whether it’s the holidays or a weekend cookout, this Smoked Turkey with Cajun Butter is a great way to turn a simple whole turkey into a show stopping main dish.
