Notes
You can use meat or vegetarian/vegan sausages for this. Try spicy sausages for a bit of a kick of heat.
For some extra freshness, add cherry tomatoes halves on top with the cheese.
This dish is a great opportunity to use leftover cheese or any vegetables you have that need using. So feel free to swap ingredients around.
Leftovers will keep in the fridge for a couple of days or in the freezer for up to 3 months.
To make this gluten free, use gluten free pasta and sausages.
If you want the top of this pasta bake to go really crispy, then you can put it under the grill for a couple of minutes.
Reserve a little of the pasta water to add to the sauce to make it nice and silky.
Make sure you don't fully cook the pasta, as it will cook a bit more in the oven and you don't want it going mushy.
We have made our own pasta sauce for this recipe, as we think it is worth the effort. However, you could use your favourite jar of pasta sauce instead, and make this a super easy meal. You might need to adjust the garlic and herbs though, depending on what pasta sauce you are using.
Feel free to use different types of pasta if you already have some in your cupboard.
For a spicier version of this, you can add a pinch of red chilli flakes.
