10 Crowd-Favorite Thanksgiving Desserts to Serve 20 Guests

Hey James, picture this: Thanksgiving dinner winds down, everyone’s stuffed from turkey and all the sides, but then that dessert table appears like a beacon of hope. Eyes light up, plates get grabbed, and suddenly the room fills with “just one more bite” energy. If you’re hosting (or bringing something) for 20 guests this year, you need desserts that feed a crowd without turning your kitchen into a war zone. These 10 crowd-favorite Thanksgiving desserts to serve 20 guests nail it—they’re classic with a twist, scalable, mostly make-ahead friendly, and guaranteed to spark seconds (and recipe requests).

I tested a bunch over the years, and trust me, nothing tanks faster than skimpy portions when Aunt Karen eyes the last slice. These bad boys use sheet pans, big bakes, or bars that slice into generous pieces. Grab your apron, pour some coffee (or that sneaky glass of wine 😉), and let’s talk sweets that actually make hosting feel doable.

1. Pumpkin Slab Pie (The Ultimate Crowd-Feeder)

This giant sheet-pan pie gives everyone pumpkin perfection without wrestling four separate crusts. Creamy filling, flaky crust, and it slices into 20+ easy pieces.

Ingredients

• 2 packages (14–16 oz each) refrigerated pie crusts (or homemade for 2 large sheets)
• 4 cans (15 oz each) pumpkin puree
• 2 cans (12 oz each) evaporated milk
• 8 large eggs
• 2 cups packed brown sugar
• 2 tbsp pumpkin pie spice
• 2 tsp ground cinnamon
• 1 tsp salt
• Whipped cream for serving

Step-by-Step Instructions

1. Preheat oven to 375°F. Grease a large 18×13-inch sheet pan (half-sheet size works great).
2. Unroll and press pie crusts into the pan, overlapping and crimping edges to fit. Poke holes with a fork.
3. Whisk together pumpkin, milk, eggs, sugar, spices, and salt until smooth.
4. Pour filling over crust. Bake 45–55 minutes until set (center barely jiggles).
5. Cool completely, then chill if making ahead. Slice into squares.

Why You’ll Love It: It’s pumpkin pie but easier and bigger—no blind-baking drama. The spices hit that cozy fall note perfectly. I once tried individual pies for a crowd… never again. This one disappears first every time.

2. Pecan Pie Bars

All the gooey, nutty glory of pecan pie, but in bar form. Way simpler to serve 20—no sticky slices sliding off plates.

Ingredients

• For crust: 3 cups flour, 1 cup cold butter (cubed), ½ cup sugar, ½ tsp salt
• For filling: 8 eggs, 3 cups corn syrup, 2 cups sugar, ½ cup melted butter, 2 tsp vanilla, 5 cups chopped pecans

Step-by-Step Instructions

1. Preheat oven to 350°F. Grease a 15×10-inch jelly roll pan.
2. Mix crust ingredients until crumbly; press into pan. Bake 18–20 minutes.
3. Whisk filling ingredients (except pecans), then stir in nuts.
4. Pour over hot crust. Bake 30–35 minutes until set.
5. Cool completely before cutting into bars.

Save

Why You’ll Love It: Crunchy top, caramel-y center—pure indulgence. These travel great for potlucks too. Pro tip: toast the pecans first for extra flavor.
