Pin It The year my grandmother decided to compete in the county fair sweet potato casserole contest, our tiny kitchen turned into a laboratory of bubbling pots and sugar dusted counters. She measured everything with her hands and taught me that the perfect mash should fold like clouds not whip like cream. That marshmallow topping caught fire under the broiler exactly once and we both stood there waving tea towels at the smoke detector laughing so hard our sides hurt.
I brought this to a Friendsgiving where nobody knew each other well and suddenly people were bonding over marshmallow preferences and childhood memories. The dish came home empty except for a single sticky spoon someone forgot to scrape clean. Now it is the first thing people ask about when the holiday potluck sign up sheet circulates around.

Ingredients
- 1.5 kg sweet potatoes peeled and cubed: Look for firm potatoes with smooth skin and no soft spots
- 60 g unsalted butter softened: Let it come to room temperature so it melts evenly into the hot potatoes
- 100 ml whole milk: Warm this slightly before adding so it incorporates beautifully
- 80 g light brown sugar: Pack it gently into the measuring cup for the right amount of molasses flavor
- 2 large eggs: Room temperature eggs blend better into the warm potato mixture
- 1 tsp vanilla extract: Pure vanilla makes all the difference here
- 1/2 tsp ground cinnamon: Freshly ground will give you the most vibrant aroma
- 1/4 tsp ground nutmeg: A little goes a long way so measure carefully
- 1/2 tsp salt: This wakes up all the sweet flavors
- 120 g mini marshmallows OR pecan streusel ingredients: Choose your adventure or use both for the ultimate topping

Pin It My cousin who swore she hated sweet potatoes tried this at Christmas and went back for thirds. The next day she texted me for the recipe saying she had been dreaming about that crunchy streusel layer. Sometimes the simplest dishes are the ones that convert people.

Make Ahead Magic
You can assemble everything except the topping up to two days before and keep it covered in the refrigerator. The flavors actually develop and deepen this way. Just bring it to room temperature for about 20 minutes before adding your topping and baking.
Topping Wisdom
The marshmallow version gives you that classic nostalgic campfire vibe while the pecan streusel offers buttery crunch and sophisticated sweetness. I have found that using both is the secret to the most talked about dish at the table. Layer pecans first then crown with marshmallows for the best of both worlds.
Serving Suggestions
This casserole holds its own next to roasted turkey glazed ham or even a simple weekday roast chicken. The sweetness balances perfectly with savory sides like green beans or Brussels sprouts.
- Serve it in the baking dish to keep that gorgeous topping intact
- Have extra marshmallows ready because someone always wants more
- Reheat leftovers in the oven not the microwave to preserve the texture

Recipe FAQs
- β Can I make sweet potato casserole ahead of time?
Yes, assemble the casserole without toppings and refrigerate for up to 24 hours. Add marshmallows or pecan streusel just before baking.
- β What's the difference between marshmallow and pecan topping?
Marshmallow topping creates a sweet, fluffy, golden-browned layer that kids love. Pecan streusel adds crunchy texture with buttery, nutty flavor. You can also use both together.
- β Can I use canned sweet potatoes?
Fresh sweet potatoes yield the best flavor and texture, but you can substitute canned (drained well). Reduce the baking time slightly since they're already cooked.
- β How do I prevent marshmallows from burning?
Watch closely during the last 5 minutes of baking. Marshmallows go from golden to burned quickly. If they brown too fast, tent with foil.
- β Can I make this vegetarian or vegan?
The base is naturally vegetarian. For vegan, use plant-based milk and butter, substitute eggs with flax eggs, and choose vegan marshmallows or stick with pecan topping.
