Slice them in half length-ways. Trim the ends if you like.
Spoon out the insides. Just take it out (leave about 1 centimeter in) until you end up with boat-like shells.
Now give the zucchini pulp a good chop, also chop a small onion and 1/2 a tomato while you’re at it. Use only half or things will become too fluid.
Sautee the onions in one tbsp oil or butter.
When the onions are almost done, add 1/4 tsp curry powder and cook everything for an additional 30 seconds. No longer or the curry powder will turn bitter. When they’re done, transfer them to a big bowl.
Cook a few slices of bacon, if you prefer, and let them drain on a paper towel.
Add 1 tsp dried thyme, 1/4 to 1/2 tsp salt, 1 heaping tbsp sour cream, a good pinch of pepper, the zucchini pulp, the tomato and crumble the bacon in as well.
Lightly butter a baking dish and put the zucchini boats in. Grab a spoon and fill the shells with the mix. Sprinkle some aged cheese on top.
Put them in a preheated oven; give them about 20 minutes and then turn on the grill until the top is golden brown. Sprinkle some coarsely chopped curly leaf parsley on top – and you’re done!
