Pecan Crunch Sweet Potato Casserole (No Marshmallows!)

If you’ve ever thought sweet potato casserole was too sweet, you’re not alone — my husband said the same thing… until he tried this version. Now it’s the one dish everyone asks me to bring to Friendsgiving and Thanksgiving every year!

This sweet potato casserole with no marshmallows is the perfect balance of creamy, rich, and slightly sweet — topped with a buttery pecan crunch that makes every bite irresistible. It’s inspired by Trisha Yearwood’s famous sweet potato soufflé, but with my own twist: a make-ahead version that saves you time on the big day.

How to Make Sweet Potato Casserole Without Marshmallows

Step 1: Cook the Sweet Potatoes

Peel and quarter 5 sweet potatoes. Place them in your Instant Pot with just enough water to cover and add ½ teaspoon of salt. Pressure cook on high for 3 minutes, then quick release and drain.

Step 2: Mash and Mix

Add 1 stick of butter to the warm potatoes and mash until smooth. Mix in sugar, milk, vanilla extract, maple syrup, and flour until well combined. Let it cool slightly, then stir in 2 eggs.

Step 3: Add to Baking Dish

Pour the sweet potato mixture into a 9×13 casserole dish.

Step 4: Make the Pecan Crunch Topping

In a bowl, combine pecans, flour, brown sugar, and butter. Use a fork, your hands, or a pastry cutter until a crumble forms. Sprinkle evenly over the sweet potato mixture.

Step 5: Refrigerate Overnight

Cover the casserole and refrigerate overnight. This lets the flavors meld and makes your holiday morning so much easier.

Step 6: Bake and Serve

When ready to bake, remove the casserole from the fridge about 30 minutes before baking. Uncover and bake at 350°F for 40 minutes, or until bubbly and golden on top.

Serve warm — and get ready for the compliments to roll in!
