Servings: persons

2 whole Large Sweet Potatoes, Thinly Sliced
1 stick Butter
1 whole Vanilla Bean
2-1/2 cups Heavy Cream, Divided Use
1 pinch Nutmeg
1 pinch Salt
2 Tablespoons Granulated Sugar
2 Tablespoons Flour
2 whole Large Tart Green Apples, Cored And Thinly Sliced
1 cup Gruyere, Sliced Thin
1 cup Sharp White Cheddar, Shredded
1/2 cups Brown Sugar
1/2 cups Dried Cherries Or Cranberries

1
Preheat oven to 400 F. Grease a 2 1/2 quart casserole dish. Layer 1 sliced sweet potato into the dish with the edges overlapping and set aside.
2
Melt butter in a medium saucepan over medium heat. Slice the vanilla bean lengthwise, scrape seeds out with a knife and add seeds and the whole bean to the butter along with 2 cups of cream, grated nutmeg, salt and 2 tablespoons sugar. Let the mixture simmer very low for 10 minutes (turn down the heat if it starts to simmer too much). After 10 minutes remove the pan from the heat.
3
In a small container add flour to 1/2 cup cold cream and stir it to dissolve completely.
4
Slowly whisk cream and flour mixture into the vanilla mixture and then bring the temperature up to medium, stirring frequently. When bubbles form at the edges remove from heat. It should begin to thicken at this point.
5
Slice apples and layer 1 apple over sweet potatoes with the edges overlapping. Layer half the cheeses over the apples. Pour half the vanilla custard mixture over the top. Repeat the process with remaining ingredients.
6
Press down with your hands (they will get a little messy) making sure the custard like liquid gets in all the layers.
7
Bake for 40 minutes to 1 hour until the edges are good and bubbly.
8
Remove from oven and sprinkle top liberally with brown sugar and dried cherries. Then put it under your broiler for 3-4 minutes to get a crusty top and melt the brown sugar.

Tips for the best results

Read through all the steps once before you start and measure out your ingredients first — it makes everything go more smoothly.
Taste as you go and adjust the seasoning before serving.
Avoid overcrowding the pan — cook in batches if needed for the best texture.
Let the dish rest for a few minutes before serving so the flavors settle.
Store leftovers in an airtight container in the fridge and enjoy within a few days.

Variations & substitutions

Use a neutral oil or a plant-based spread in place of butter for a dairy-free version.
Brown sugar instead of white sugar adds a deeper, more caramel-like flavor.
A good 1:1 gluten-free flour blend works well if you need a gluten-free version.
Coconut cream is a reliable plant-based alternative to dairy cream.
