What you'll need:
Sweet potato mixture:
4 medium sized sweet potatoes
1/2 cup brown butter ( about 150 g)
3/4 cup dark brown sugar ( packed)
3 tbsp pure maple syrup
1/4 cup granulated sugar
1 egg ( lightly beaten)
1/3 cup whole milk ( add to 2-3 tbsp more if the mixture look to thick or dry)
1 1/2 tsp vanilla bean paste ( or vanilla extract)
1 tsp kosher salt
1/2 tsp cinnamon
1/4 tsp ground nutmeg ( or 1/8 tsp of freshly grated nutmeg)
Pecan topping
1 cup pecans ( chopped & roasted)
1 cup light brown sugar ( packed)
1/3 cup all-purpose flour
1/3 cup brown butter ( about 75 g)
Directions:
Roast the Sweet Potatoes
Preheat oven to 425.
Pierce potatoes with a fork a few times and place on a foil lined baking sheet and roast for 60-65 minutes, or until a knife slides in easily.
Let cool until you can handle them, then reduce oven to 350.
Roast your pecans:
Spread pecans on a sheet pan.
Roast 6-8 minutes, stirring halfway, until fragrant. Let them cool and then chop.
Make the Brown Butter
Add 1/2 cup butter + 1/3 cup butter ( this is all the butter for the recipe) to a saucepan over medium heat. Let it melt, stirring occasionally. The butter will foam, then subside and brown specks will appear at the bottom. Cook until it turns a deep golden color and smells nutty ( The whole process should take 5-8 minutes)
Divide it roughly into a 1/2 cup for the sweet potatoes and 1/3 cup for the topping ( make sure to get all the brown bits)
Prepare the sweet potato mixture
Peel the sweet potatoes and add to a bowl. Mash to your preferred texture ( you can also use a handheld mixer for a smoother consistency)
Add brown butter , dark brown sugar , granulated sugar, milk , maple syrup, vanilla bean paste, salt, cinnamon, and nutmeg. Mix well. (Taste and adjust if necessary)
Add the beaten egg and mix until combined.
Make the pecan topping:
In a seperate bowl combine light brown sugar, flour, roasted pecans 1/3 cup of brown butter.. Mix until evenly coated.
Assemble the casserole
Pour the sweet potato casserole into a casserole dish. Sprinkle the topping evenly over the sweet potatoes.
Bake at 350 uncovered for 35- 40 minutes, or until the topping is melted. Top with flaky sea salt & ENJOY!
Important notes
If your sweet potatoes were roasted ahead of time and are cold, cover the casserole with foil for the first 10-20 minutes of baking so the center can heat through. Then uncover and continue baking until the topping melts and caramelizes. Cold sweet potatoes may add an extra 10-20 minutes to the bake time.
You don't have to use all of the topping if you prefer a lighter layer. I personally love a generous crunchy topping, so use as much or as little as you like.
This serves about 6-7 ppl. Feel free to double the recipe if needed. ( highly recommend if you want leftovers or seconds)
