Sweet potato roulade with christmas stuffing (with photos)

[Lellyj]

I was very pleased with the vegetarian meal I made for my teenagers on Christmas day.  It has 3 elements, all easy to do in tmx.  I wanted something special for them while the rest of us were having a bit of a meat fest.  I got the recipe from taste.com:  http://www.taste.com.au/recipes/6033/sweet+potato+leek+roulade+with+xmas+stuffing

Sweet potato roulade with christmas stuffing
Number of People 6:
Ingredients:
  
 Roulade
    20ml (1 tbs) olive oil
    1 leek, cut into chunks
    60g butter
    1/3 cup plain flour
    300ml milk
    4 eggs, separated
    1/2 cup grated cheddar cheese
    1/4 cup grated parmesan
  
 Stuffing
    1 brown onion, peeled & quartered
    2 garlic cloves, crushed
    30g unsalted butter
    1 1/2 cups fresh white breadcrumbs (I used 2 slices of rye bread)
    1 tbs chopped fresh sage
    1 tbs chopped flat-leaf parsley
    
Filling
    500g sweet potato, peeled, chopped
    15g unsalted butter
    100ml thin cream
    1/2 tsp freshly grated nutmeg


Preparation:

For stuffing
Chop onion and garlic, 5 or 6 seconds, speed 6.
Add butter and cook at 4 minutes 100, speed 1
Add two slices of bread and herbs and chop speed 6 for 15 seconds, push down and chop again if required.
Cook another minute, speed 1, 100.
Taste and season, set aside


For roulade
Preheat oven to 180C.
Grease and line a swiss roll tin.
Chop leek in tmx bowl for a few seconds, speed six.  
Add olive oil and cook 5mins 100, speed  1
Remove from bowl and set aside (I didn't wash bowl)
Add butter, flour and milk to bowl.  Cook 7 minutes, speed 4, 90 degrees until sauce has thickened.
Remove  bowl from stand and allow to cool for a few minutes, then place jug back on stand and add egg yolks one at a time mixing briefly at speed 3 or 4 after each addition.  Taste and season with salt and pepper.
Whisk egg whites till stiff (Note:  I just whisked these by hand while the white sauce mix was cooking because I couldn't be bothered cleaning out the tmx.  If you wanted to, you could of course beat in tmx, especially if you have two bowls, or you could use another kitchen appliance)
Add butterfly to tmx bowl. Add 1/4 of egg whites to white sauce and mix in, speed 4 for a few seconds then add the remaining egg whites and mix in quickly.  
Add cooked leek and grated cheese until just combined.
Pour mixture into swiss roll tin and bake for 20-25 minutes until puffed and golden.

For filling
Meanwhile, add some boiling water (about 700g) to the bowl and cook sweet potato in steaming basked at varoma temp until tender (I think this took about 18 minutes, but didn't write it down.) Mash with cream and nutmeg and butter.

To assemble
When the roulade is cooked, place a clean tea towel on your workbench and sprinkle with the parmesan. Turn the roulade out onto the tea towel and peel off the baking paper. Allow to cool for 1-2 minutes, then spread the sweet potato over the roulade.

Sprinkle the stuffing over the sweet potato. Using the edge of the tea towel, carefully roll up the roulade from the longest side finishing with the seam-side down.

Note the parmesan cheese melted on the hot roulade which tasted nice, but I sprinkled with more before serving.

According to Taste, you can make the roulade the day before. Simply wrap in foil and warm gently in the oven before serving.

That looks very appetising, thanks for posting the recipe.

Thanks Lelly, I'm looking for a couple of vegetarian recipes for a get together on Monday.
Do you think it would be OK cold or is it best served warm?

I thought about making this for xmas but it looked too hard. I might give it a go now. Was it yummy?

[Lellyj]

Hi Mcmich, the leftovers were quite nice cold, but I prefered it warm, the sweet potato was a bit "solid" cold. It is apperently easy to heat.

Hazelnut, not hard with TMX but a bit time consuming. I thought it was very tasty and the vegetarians were very happy.

Hope you like it if you decide to try!

Thanks Lelly, will make ahead and warm in the oven before serving.

Made this last night. It was lovely. A lot of steps but well worth it.

It sounds nice. I should imagine that when you've made it once it will seem easier next time.

[Lellyj]

That's great Mcmich.  I thought the same thing, worth it especially for a special occasion.  I think you're probably right Cookie, probably easier the second time round.
