Preheat the oven to 375 F/ 190 C/ 180 fan/ gas mark 5. Cut each eggplant twice lengthwise to get 4 long strips (if using 2 eggplants you'll have 8 strips in total). Bake in the centre of the oven for 40 minutes.
Place each strip skin side down on top of a large sheet lined with parchment paper. Brush with a little oil (approx. 1 tbsp) or use cooking spray then season lightly and sprinkle with onion and garlic granules.
Remove from the oven and cut the eggplant into chunks (leave the oven on). Stir into the casserole along with the pasta (as in Step 4 below).
Make the pasta bake
Add the pasta to a pot of boiling water, stir, bring to the boil then cook for 4 minutes (the pasta should only be partly cooked). Remove from the heat, pour into a strainer and set aside while you prepare the rest of the ingredients.
In a large shallow pan heat up 1.5 tablespoons of oil, add the garlic, onion and bell pepper and fry gently for about 5 minutes stirring often.
Add the tomatoes, sun-dried tomatoes, balsamic vinegar, paprika, herbs and stock, stir, cover, bring to the boil then simmer for 5 minutes.
Remove from the heat, add the precooked pasta, eggplant, several grinds of pepper and stir thoroughly.
Scatter the parmesan over the top of your eggplant and pasta casserole and bake in the centre of the oven for 20 minutes.
Remove from the oven, garnish with fresh basil (optional) and serve.
Notes
Use firm eggplants with healthy, glossy skin.
You can either coat the eggplant with oil (1 tbsp) or use cooking spray before roasting.
There is no need to turn the eggplant over as it roasts. Don't worry if becomes a little dry around the edges - it will rehydrate once you combine it with the other ingredients.
To save time precook the pasta and prepare the sauce as you are waiting for the eggplant to roast.
If using canned tomatoes with added ingredients, such as herbs or garlic, lower the proportions of these ingredients in the recipe (if applicable).
Adjust the amount of cheese to your taste.
Bake this pasta with eggplant as soon as you’ve assembled it.
Best served immediately. Refrigerate the leftovers for up to 3 days.
Not suitable for freezing (the pasta would absorb too much moisture as it cools and may become soggy).
